Description

本発明は漏電電流等により発生される安全事故を予防させる電源遮断機に関することで、特に、電源遮断機に装着されて電源を遮断する操作ノブのリターン過程が自動になるようにして効率性を増大させるようにした電源遮断機用操作ノブのリターン装置に関する。   The present invention relates to a power breaker that prevents a safety accident caused by a leakage current or the like, and in particular, efficiency is improved by automatically returning a control knob that is attached to the power breaker and shuts off the power. The present invention relates to a return device for an operation knob for a power breaker that is increased.

一般に、電源遮断機は分電盤内に設置されて漏電のような異常電流が発生すると自動に電源を遮断する安全装置であって、このような電源遮断機は人体に対する感電事故とか漏電による火災及び過電流と短絡などによる安全事故等を予防するための目的で用いられる電裝品の一種である。   Generally, a power breaker is a safety device that is installed in a distribution board and automatically shuts off the power supply when an abnormal current such as a leakage occurs. Such a power breaker can cause an electric shock accident or a fire due to leakage. It is a type of electrical appliance used for the purpose of preventing safety accidents due to overcurrent and short circuit.

最近には有・無線インターネット等を利用した遠隔制御によって作動する電源遮断機が多く研究されていて、特に、電源遮断機のオン・オフ動作による作動が容易でなければならず、システムの誤作動がなく、組立性が簡便な構造の製品に対する研究が要求される。   Recently, many researches have been conducted on power circuit breakers that operate by remote control using wired / wireless Internet, etc. Especially, it must be easy to operate by turning on / off the power circuit breaker, and the system malfunctions. There is no need for research on products with a structure that is easy to assemble.

例えば、本願出願人に譲渡された登録考案で、本発明の従来技術で引用される図１の“開閉装置”（韓国実用新案登録第２０−０３５３０５１号）によると、開閉器１００の内部にノブ１０３の開閉過程でヒンジ１４１を沿って回転し、ソレノイド１０７のプランジャー１１５がピボット結合されて連動するノブボディー１１３が設置され、前記開閉器１００の底面にヒンジ１３５を沿って回転し、その体にシャフト１３３を装着した支持台１１１が設置され、前記ノブボディー１１３のヒンジ１４１にノブ１０３の回転力を通じて回転しながらスプリング１２３によってリターンし、その先端部にシャフト１３３の外周面に触れ合う第１，２（２２１，２２３）を具備した弓部１０５が設置された構成が提案されたことがある。   For example, according to the “switching device” (Korean Utility Model Registration No. 20-0353051) of FIG. 1 which is a registration device assigned to the applicant of the present application and cited in the prior art of the present invention, a knob is provided inside the switch 100. 103 is rotated along the hinge 141 during the opening and closing process 103, the plunger body 115 of the solenoid 107 is pivotally coupled to the knob body 113, and the body is rotated along the hinge 135 on the bottom surface of the switch 100. A support base 111 having a shaft 133 attached thereto is installed, and is returned to the hinge 141 of the knob body 113 by the spring 123 while rotating through the rotational force of the knob 103. There has been proposed a configuration in which a bow 105 having 2 (221, 223) is installed.

ここで、ソレノイド１０７に電源が供給される場合、プランジャー１１５によってノブボディー１１３がヒンジ１４１を中心で図で時計の方向に回動し、このノブボディー１１３の裏面に装着された駆動ポール１１７が連動されて接触スイッチ１０９の接点を離れて開閉器１００が接触スイッチ１０９をトリップさせることである。   Here, when power is supplied to the solenoid 107, the knob body 113 is rotated clockwise around the hinge 141 by the plunger 115, and the drive pole 117 mounted on the back surface of the knob body 113 is moved. The switch 100 trips the contact switch 109 when the contact of the contact switch 109 is released.

同時に、ノブボディー１１３に装着された弓部１０５が連動して支持台１１１のシャフト１３３を下向に加圧するので、弓部１０５の先端部を構成する第２加圧部２２３がシャフト１３３の外周面に触れ合って支持台１１１が安定状態にセッティングされる。   At the same time, the bow 105 attached to the knob body 113 interlocks and pressurizes the shaft 133 of the support base 111 downward, so that the second pressurizing part 223 constituting the tip of the bow 105 becomes the outer periphery of the shaft 133. The support 111 is set in a stable state by touching the surface.

一方、ソレノイド１０７の電源が遮断される場合、プランジャー１１５がリターンされてノブボディー１１３がリターンされるので、駆動ポール１１７と接触スイッチ１０９が接続して“オン”作動され、弓部１０５がスプリング１２５によりリターンされ、支持台１１１はスプリング１２３によりリターンされて開閉器１００が正常状態に復帰することである。   On the other hand, when the power source of the solenoid 107 is cut off, the plunger 115 is returned and the knob body 113 is returned, so that the drive pole 117 and the contact switch 109 are connected to operate “on”, and the bow 105 is moved to the spring. 125 is returned, and the support base 111 is returned by the spring 123 to return the switch 100 to a normal state.

ところで、開閉器１００はソレノイド１０７を用いて異常電流の遮断を可能であるようにするが、ノブボディー１１３にソレノイドのプランジャー１１５が直接的にヒンジ式で結合されて連動する状態であるので、ノブボディー１１３のリターンによる衝撃荷重で作動騒音が発生され、非接触式運動により不正確に作動されるので、信頼性が低下される問題点がある。   By the way, although the switch 100 is made to be able to interrupt | block abnormal current using the solenoid 107, since the plunger 115 of a solenoid is directly connected with the knob body 113 by a hinge type, it is in the state interlock | cooperated, The operation noise is generated by the impact load due to the return of the knob body 113, and the operation is inaccurate due to the non-contact type motion.

そして、開閉器１００でソレノイド１０７の作動安全性を増大させるための手段として弓部１０５と支持台１１１に第１，２加圧部１２１、１２３とシャフト１３３を各々形成しなければならなく、リターンの手段で多数のスプリング１２３，１２５を設置しなければならないので、各種の費用が増大される問題点がある。   As a means for increasing the operational safety of the solenoid 107 in the switch 100, the first and second pressurizing parts 121 and 123 and the shaft 133 must be respectively formed on the bow part 105 and the support base 111, and the return Since a large number of springs 123 and 125 must be installed by this means, there is a problem in that various costs are increased.

このため、本発明は前記のような問題点を解消するためのことであり、非接触式作動メカニズムを止揚し、トリップの以後に異常電流状態が解除されると、操作ノブのリターン過程が自動になるようにして使用上の効率性を増大させた電源遮断機に適合なノブリターン装置を提供ことがその目的である。   For this reason, the present invention is to solve the above-described problems. When the non-contact operation mechanism is stopped and the abnormal current state is released after the trip, the return process of the operation knob is automatically performed. It is an object of the present invention to provide a knob return device that is suitable for a power circuit breaker with increased use efficiency.

前記の目的を達成するための本発明は、固定軸を中心で回動し、上部にハウジングの上面部の上に突出された上段部と下部に左下段部と右下段部を各々具備した操作ノブと、前記操作ノブの左下段部にリンク連結されたラッチバーを利用して、前記ハウジングの底面に構成された一対の接触スイッチを開閉させるようにし、前記操作ノブの右側方に前記固定軸に平行な第１補助軸を中心で回動し、下部に支持顎を具備し、上部には接触部を具備したトリップバーと、前記操作ノブの左側方に前記固定軸に平行な第２補助軸を中心で回動する回動レバーと、電気的信号により駆動されるソレノイドの塊が装着され、前記回動レバーの一側部にソレノイドの塊のプランジャーとピボット結合される少なくとも一つ以上の駆動リンクが連結され、この回動レバーの他側部に操作ノブとラッチバーにピボット連結される少なくとも一つ以上の被駆動リンクがピボット連結されてなり、前記ラッチバーは弾性体に構成されヘッド部は被駆動リンクにピボット結合され、レッグ部は自由端に形成されながら前記トリップバーの支持顎に支持されるようにした操作ノブのリターン装置を提供する。   In order to achieve the above object, the present invention is an operation that rotates around a fixed shaft, and has an upper step protruding above the upper surface of the housing and a lower left step and a lower right step at the lower portion. Using a knob and a latch bar linked to the lower left step of the operation knob, a pair of contact switches configured on the bottom surface of the housing is opened and closed, and the fixed shaft is formed on the right side of the operation knob. A trip bar having a support jaw in the lower part and a contact part in the upper part, and a second auxiliary axis parallel to the fixed axis on the left side of the operation knob. At least one or more of a pivot lever and a solenoid lump that are driven by an electrical signal are pivotally connected to one side of the pivot lever and a plunger of the solenoid lump. The drive link is connected. At least one driven link pivotally connected to the operation knob and the latch bar is pivotally connected to the other side of the rotating lever. The latch bar is formed of an elastic body, and the head portion is pivotally connected to the driven link. The leg part is provided with a return device for the operation knob which is formed at the free end and is supported by the support jaw of the trip bar.

本発明による電源遮断機用操作ノブのリターン装置によると電源遮断機に装着されて電源遮断機が“オン”の状態で異常電流が感知されないかぎり、ソレノイドの持続的な駆動電流がなくても“オン”の状態を維持するので、自動に操作ノブがリターンされる電源遮断機でメカニズムの具現による消費電力が最小かされるのみならず、ラッチバーの自体の弾性によって充分なスイッチの接触圧力の実現が可能であり、異常電流感知の結果によってオンーオフ状態の転換が容易し、操作ノブを強制に“オン”の位置に操作した状態でも異常電流の感知時に接点のスイッチが開けるようになっていて安全性が優れ、構造が簡単であって製作費用を減少させる効果がある。   According to the return device of the operation knob for the power circuit breaker according to the present invention, unless an abnormal current is sensed when the power circuit breaker is mounted and the power circuit breaker is “on”, even if there is no continuous drive current of the solenoid, Maintaining the “on” state, the power breaker that automatically returns the operation knob not only minimizes the power consumption due to the implementation of the mechanism, but also realizes sufficient switch contact pressure due to the elasticity of the latch bar itself It is possible to change the ON / OFF state easily according to the result of abnormal current detection, and it is safe because the contact switch can be opened when abnormal current is detected even when the operation knob is forced to the “ON” position. Excellent in structure and simple structure, reducing the manufacturing cost.

また、本発明による電源遮断機用操作ノブのリターン装置によると、電源遮断機が“オン”の状態でソレノイドの持続的な駆動電流のなしにも“オン”の状態が維持され、リターンの信号によって操作ノブのリターン動作の自動化が容易になり、電源遮断機の作動メカニズムの具現による消費電力が最小化されて故障の発生率が減少し、装備の寿命が増加されるのみならず、手動操作時まで放置される場合に現れる電源の持続的な遮断により発生する工場の原料損傷、操業中断または情報システムの動作中断による情報損失などの２次的な損失を最小化することにおいて、産業上の利用可能性が提供されることである。   Further, according to the return device of the operation knob for the power breaker according to the present invention, the “ON” state is maintained even when the power breaker is “ON” and there is no continuous drive current of the solenoid. This makes it easy to automate the return movement of the control knob, minimizes power consumption due to the implementation mechanism of the power breaker, reduces the rate of failure, increases the life of the equipment, and also allows manual operation In minimizing secondary losses such as information loss due to factory raw material damage, operation interruption or information system operation that occurs due to the continuous interruption of power supply that appears when left unattended, The availability is to be provided.

以下、添付された図面を参照して本発明による実施例を説明すると次のようである。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

本発明による電源遮断機１０はハウジング１１とフタ１８によって箱体になり、その内部空間に操作ノブ１４とラッチバー１５と接触スイッチ１６等が収容され、特に、ハウジング１１に内蔵された操作ノブ１４が固定軸１３を中心で回転し、操作ノブ１４の復帰手段でリターン装置２０が装着されたことを特徴とする。   The power breaker 10 according to the present invention is formed into a box by a housing 11 and a lid 18, and an operation knob 14, a latch bar 15, a contact switch 16, and the like are accommodated in the inner space. The return device 20 is mounted by the return means of the operation knob 14 by rotating around the fixed shaft 13.

一方、電源遮断機１０に通常的に含めるサージ電流を感知するための回路基板（図示せず）や他の制御装置等に関する相互結合及び作動構造は公知技術としてこれに対する詳しい説明は省略する。   On the other hand, a mutual connection and operation structure relating to a circuit board (not shown) and other control devices for detecting a surge current normally included in the power breaker 10 are well known in the art, and detailed description thereof is omitted.

前記操作ノブ１４は、電源遮断機１０の収容空間に横に設置された固定軸１３を中心で正・逆回転できるように形成されたことで、その体の上端部がフタ１８の上面部の上に突出されて回動操作ができるようにし、下部は左下端部と右下端部を各々具備し、逆回転（図２及び図３で反時計の方向）を抵抗するようにするトルションスプリング等の弾性手段を具備する。   The operation knob 14 is formed so as to be able to rotate forward and backward around a fixed shaft 13 installed horizontally in the accommodation space of the power breaker 10, so that the upper end portion of the body is the upper surface portion of the lid 18. A torsion spring or the like that protrudes upward so that it can be rotated, and that the lower part has a left lower end and a right lower end, respectively, and resists reverse rotation (counterclockwise in FIGS. 2 and 3). The elastic means is provided.

The leg portion is a free end and a support jaw 17a below the trip bar 17 is provided. The material is formed so as to have a limited hinge motion and is made of an elastic material. On the other hand, a push bar (Crossbar, 15a) is attached to the body of the latch bar 15 in the horizontal direction so that both contacts of the contact switch 16 can be pressurized.

前記トリップバー１７は操作ノブの右側方に前記固定軸１３に平行な第１補助軸１７ｂを中心で回動し、下部に支持顎１７ａを具備し、上部には接触部を具備し、スプリングによって逆回転抵抗が掛かるようになっていて、トリップソレノイド１９のプランジャー動作（図示せず）やバイメタルの曲がりにより接触部がタッチされる場合、トリップバー１７が回動しながら、支持顎１７ａがラッチバーのレッグ部を解除できるように構成される。   The trip bar 17 rotates about the first auxiliary shaft 17b parallel to the fixed shaft 13 on the right side of the operation knob, has a support jaw 17a at the lower portion, has a contact portion at the upper portion, and is spring-loaded.

It is comprised so that the leg part of can be cancelled | released.

前記ソレノイドの塊２５は、軽筒の外周面にコイルが巻いた状態であり、軽筒の中空内にプランジャー２５ａが往復運動するように設置されて駆動コイルにサージ電流が印加される場合、瞬間的に電子力を発生させてプランジャーが軽筒内に吸引されるように形成されたことであり、ハウジング内に水平または垂直方向等適切な方向に設置される。   The solenoid lump 25 is in a state where a coil is wound around the outer peripheral surface of a light cylinder, and when the plunger 25a is reciprocated in the hollow of the light cylinder and a surge current is applied to the drive coil, The plunger is formed so that an electronic force is instantaneously generated to be sucked into the light cylinder, and the plunger is installed in an appropriate direction such as a horizontal or vertical direction in the housing.

前記回動レバー２２は、操作ノブ１４とソレノイドの塊２５との間の空間に設置されたことで、固定軸１３に平行な第２補助軸２１を中心で回動し、軸線と離隔された位置の左右に左右作用部を具備してその外観が概略三角形状に形成されて固定軸を中心で回転力を伝達するように構成される。   The rotation lever 22 is installed in the space between the operation knob 14 and the solenoid lump 25, so that it rotates about the second auxiliary shaft 21 parallel to the fixed shaft 13 and is separated from the axis. The left and right action portions are provided on the left and right sides of the position, and the outer appearance thereof is formed in a substantially triangular shape so that the rotational force is transmitted around the fixed axis.

前記駆動リンク２３は、回動レバー２２とソレノイドの塊２５の間に設置されて力を伝達する少なくとも一つ以上の板状の部材であって、その一端部が回動レバー２２の左端作用部にピボット結合され、その他端部がソレノイドの塊２５のプランジャー２５ａの上端にピボット結合されて運動する。   The drive link 23 is at least one plate-like member that is installed between the rotation lever 22 and the solenoid lump 25 and transmits a force, and one end portion of the drive link 23 is a left end action portion of the rotation lever 22. The other end is pivotally connected to the upper end of the plunger 25a of the solenoid lump 25 to move.

駆動リンク２３は、図４のようにプランジャー２５ａに直接ヒンジ式で連結することもできるし、図５のように媒介部材２３ａを通じてプランジャー２５ａに連結することもできるが、図６のように駆動リンク２３を排除して回動レバー２２の左端作用部に長凹溝を形成されてプランジャー２５ａに結合することもできる。本発明ではこれらの全ては引張力リンク手段で規定される。   The drive link 23 can be directly hingedly connected to the plunger 25a as shown in FIG. 4, or can be connected to the plunger 25a through the intermediate member 23a as shown in FIG. 5, but as shown in FIG. It is also possible to eliminate the drive link 23 and form a long concave groove in the left end action portion of the rotation lever 22 so as to be coupled to the plunger 25a. In the present invention, all of these are defined by the tensile force link means.

前記被駆動リンク２４は、回動レバー２２と操作ノブ１４の間の空間に設置されて回動する板状の部材であって、三つの作用部を具備し、その第１作用部が回動レバー２２にリンク結合され、第２及び第３作用部が操作ノブ１４とラッチバー１５に各々ピボット結合されて運動する。被駆動リンク２４の第１作用部は補助リンク２６を利用して回動レバー２２にリンク結合することが望ましい。   The driven link 24 is a plate-like member that is installed in a space between the rotation lever 22 and the operation knob 14 and rotates, and includes three action portions, and the first action portion is turned. The lever 22 is linked and the second and third action portions are pivotally connected to the operation knob 14 and the latch bar 15 to move. The first working portion of the driven link 24 is preferably link-coupled to the rotating lever 22 using the auxiliary link 26.

また、回動レバー２２の右端作用部に図６のような長凹溝を形成されて駆動リンク２３及び被駆動リンク２４の回動過程で発生する衝撃力を吸収するように構成することができる。前記被駆動リンク２４に連結される長凹溝の形状を適切に形成して補助リンク２６を省略し、被駆動リンク２４を直接に回動レバーに連結することもできるが、ここで、これは全て引張力リンク手段に規定される。   Further, a long concave groove as shown in FIG. 6 is formed in the right end action portion of the rotation lever 22 so that the impact force generated during the rotation process of the drive link 23 and the driven link 24 can be absorbed. . The shape of the long groove connected to the driven link 24 may be appropriately formed, the auxiliary link 26 may be omitted, and the driven link 24 may be directly connected to the rotating lever. All are defined in the tensile force link means.

以下、本発明による作用を説明すると次のようである。
まず、図２は、電源遮断機の“オフ”の状態で、接触スイッチ１６が開けていて、ラッチバーのレッグ部はトリップバーの支持顎１７ａから解除されていて、操作ノブは“オフ”の位置に置いていて、プランジャー２５ａはソレノイド軽筒から離脱されている状態である。 Hereinafter, the operation of the present invention will be described as follows.
First, FIG. 2 shows that the power switch-off device is in the “off” state, the contact switch 16 is open, the leg portion of the latch bar is released from the support jaw 17a of the trip bar, and the operation knob is in the “off” position. The plunger 25a is detached from the solenoid light cylinder.

操作ノブのリターン信号により電源遮断機１０のソレノイド２５にサージ電流が印加されて電子力を発生する場合、図３のようにプランジャー２５ａが吸引されるので、プランジャー２５ａに駆動リンク２３を通じて連結された回動レバー２２が反時計方向に回転する。   When an electronic force is generated by applying a surge current to the solenoid 25 of the power breaker 10 by the return signal of the operation knob, the plunger 25a is attracted as shown in FIG. The rotated lever 22 thus rotated rotates counterclockwise.

このため、回動レバー２２に被駆動リンク２４を通じて連結された操作ノブ１４の左下端部が押されて操作ノブ１４が反時計方向に逆回転して“オン”の位置に復帰する。   Therefore, the lower left end portion of the operation knob 14 connected to the rotation lever 22 through the driven link 24 is pushed, and the operation knob 14 rotates counterclockwise and returns to the “on” position.

さらに、操作ノブ１４の左下端部に被駆動リンク２４を通じてピボット結合されたラッチバー１５のヘッド部が下向運動されると共にラッチバーのレッグ部がトリップバー１７の支持顎１７ａにかみ合うように操作ノブの右下端部がラッチバーの体を押すので、ラッチバーがレッグ部が支持されて回転しながらラッチバー１５に横に装着された押し棒１５ａが接点スイッチ１６を押して電源遮断機を“オン”の状態にする。   Further, the head portion of the latch bar 15 pivotally connected to the lower left end portion of the operation knob 14 through the driven link 24 is moved downward, and the leg portion of the latch bar is engaged with the support jaw 17a of the trip bar 17 so as to be engaged. Since the lower right end pushes the body of the latch bar, the push bar 15a mounted on the side of the latch bar 15 pushes the contact switch 16 while the latch bar is supported by the leg portion and rotates to turn the power breaker on. .

この状態ではラッチ部材１５の弾性によって操作ノブの左下端部に加える逆回転力が操作ノブ１４のトルションスプリングによる正回転より大きい状態であるので、ソレノイドに印加されたサージ電流が除去されてプランジャーの吸引力がなくなっても“オン”の状態がそのまま維持される。   In this state, the reverse rotational force applied to the lower left end of the operation knob due to the elasticity of the latch member 15 is larger than the normal rotation by the torsion spring of the operation knob 14, so that the surge current applied to the solenoid is removed and the plunger Even if the suction force is lost, the “on” state is maintained as it is.

一方、ソレノイド２５に印加されたサージ電流が一定の時間が過ぎてなくなった状態で異常電流信号によって駆動されるトリップソレノイド１９のプランジャーがトリップバーの接触部をタッチすると、トリップバーの下部が回動しながら、支持顎１７ａにかけていたラッチバーのレッグ部を解除することになって“オン”の状態で維持されたラッチバー１５の弾性力が消滅されながら操作ノブ１４はトルションスプリングの復元力により時計方向に回動して図２のように“オフ”の位置に動き、駆動リンク２３を通じて連結されたプランジャー２５ａが突出される。   On the other hand, when the plunger of the trip solenoid 19 driven by the abnormal current signal touches the contact portion of the trip bar while the surge current applied to the solenoid 25 has passed for a certain time, the lower portion of the trip bar rotates. The operating knob 14 is rotated clockwise by the restoring force of the torsion spring while the elastic force of the latch bar 15 maintained in the “on” state disappears while the leg portion of the latch bar applied to the support jaw 17a is released while moving. 2 and moves to the “off” position as shown in FIG. 2, and the plunger 25a connected through the drive link 23 is projected.

さらに、操作ノブ１４、の左下端に被駆動リンク２４を媒介で連結されたラッチバー１５のヘッド部が持ち上げられ、レッグ部は支持顎１７ａから解除されるので、接触スイッチ１６を押している押し棒１５ａの加圧力が失われ、接触スイッチ１６に具備されたスプリングによって接点が開けて電源遮断機が“オフ”の状態で維持される。   Further, the head portion of the latch bar 15 connected to the lower left end of the operation knob 14 via the driven link 24 is lifted, and the leg portion is released from the support jaw 17a. Therefore, the push rod 15a pushing the contact switch 16 is used. The contact pressure is lost, and the contact is opened by the spring provided in the contact switch 16 so that the power breaker is maintained in the “off” state.

一方、過電流や短絡の原因が除去されていない状態で操作者が操作ノブ１４を“オフ”の位置から“オン”の位置に強制に操作する場合でもトリップソレノイドやバイメタルによってトリップバー接触部がタッチされてラッチバーのレッグ部を支持顎１７ａから解除させることによって接触スイッチ１６の接点が開けることになって操作上の事故を防止することができる。   On the other hand, even when the operator forcibly operates the operation knob 14 from the “off” position to the “on” position without removing the cause of the overcurrent or the short circuit, the trip bar contact portion is tripped by the trip solenoid or the bimetal. By touching and releasing the leg portion of the latch bar from the support jaw 17a, the contact of the contact switch 16 is opened, and an operational accident can be prevented.
