Description
Technical field
The utility model relates to killer switch equipment, particularly relates to a kind of breaker misoperation-preventing and closes interlock.
Background technology
High-tension switch cabinet is the electric equipment that mains supply field is commonly used, high-tension switch cabinet should possess and prevents by mistake point, closes circuit breaker, prevent on-load from dividing, close isolating switch (or stab contact), prevent disconnecting link with ground (or earth connection) power transmission, prevent " five prevent " functions such as charged co-grounding switch (or hanging earthing conductor).At present, the high voltage supply mating switch generally used is handcart type vacuum circuit breaker, and this Series Circuit Breakers is matching used with metal armored withdrawal-type switching device.
Mostly current interlock is to arrange two covers respectively and is connected mechanical driving with switch cabinet grounding switch and isolator operating mechanism, and wherein one group of realization is by breaker open operation interlock, other one group for stoping manual operation breaker closing.Because breaker mechanism enclosure interior is very crowded, the discrete setting of two cover interlockings need be taken more space, and part that is easy and mechanism self interferes, and causes misoperation.Can, because of both displacement action errors, circuit breaker be caused reliably not close a floodgate or sub-switching operation discrete for two cover interlockings setting.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, a kind of breaker misoperation-preventing is provided to close interlock, solve interlock in current technology easily to interfere, cause misoperation, the displacement action error of two interlocks can cause circuit breaker reliably not close a floodgate or the problem of separating brake.
For solving above technical problem, the technical solution of the utility model is:
A kind of breaker misoperation-preventing closes interlock, comprise bull stick, transmission mechanism, blocking lever, breaker open operation semiaxis buckle, mechanism's combined floodgate semiaxis, it is characterized in that, described rotarod apparatus is on circuit breaker cabinet, bull stick is connected with blocking lever by transmission mechanism, device separating brake pressing plate on blocking lever, blocking lever can be driven by transmission mechanism and move up and down, when blocking lever moves down, separating brake platen presses breaker open operation semiaxis buckle realizes the power-off of breaker open operation major loop, and mechanism's combined floodgate semiaxis that when blocking lever moves down, its bottom end blocks semicircle shape stops its rotation to guarantee that circuit breaker can not close a floodgate.Breaker misoperation-preventing described in the utility model closes interlock and drives blocking lever to move down by screwing bull stick drive transmission device, separating brake pressing plate on blocking lever was positioned at above breaker open operation semiaxis buckle originally, press breaker open operation semiaxis buckle when it moves down and realize the power-off of breaker open operation major loop, the bottom end of blocking lever is blocked combined floodgate semiaxis and is stoped its rotation to guarantee that circuit breaker can not close a floodgate simultaneously.Whole apparatus structure is simple, and the space taken is little, and breaker open operation can be realized effectively reliably to link, and stops manual operation breaker closing, avoids the appearance of accident.
Further, described transmission mechanism articulated mounting is on circuit breaker cabinet, and transmission mechanism is connected with bull stick by hinge, and the junction of transmission mechanism and blocking lever is provided with long chute, blocking lever is provided with connecting pin and is set in the long chute of transmission mechanism.The rotational movement transmission mechanism of bull stick rotates, and transmission mechanism makes blocking lever, along long chute, upper and lower moving occur, thus realizes separating brake and the anti-error closing operation of circuit breaker by turn bull stick.
Further, the top arrangement of described blocking lever has back-moving spring.Utilize the elastic force of back-moving spring that blocking lever can be made to pop up to reset and untie the lockup state of breaker open operation semiaxis buckle, mechanism's combined floodgate semiaxis, avoid occurring that blocking lever blocks due to its rotatory force and cannot carry out the phenomenon of closing operation by mechanism's combined floodgate semiaxis.
Further, described mechanism half next to axis that closes a floodgate also is provided with locating part, the advanced positions of blocking lever is between mechanism's combined floodgate semiaxis and locating part, and locating part continues after can avoiding mechanism's combined floodgate semiaxis that blocking lever is hit skew to rotate, thus increases the reliability of anti-misconnection operation.
Further, on described bull stick, device has knob, utilizes knob can reduce the rotation dynamics of applying, facilitates manual operation.
Compared with prior art, the utility model advantage is:
Circuit breaker divides by breaker misoperation-preventing conjunction interlock described in the utility model, one group of linkage unit merged into by combined floodgate interlocking, achieve breaker open operation, anti-misconnection interlock, take volume little, linkage reliability is high, stop manual operation breaker closing, prevent cutter power transmission with ground, the cabinet " five prevent " of joining realizing circuit breaker and fixed switching cabinet is interlocked; The utility model structure is simple, and reliability is strong, simple to operate, and high financial profit is practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of bull stick.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Disclosed in the utility model embodiment, a kind of breaker misoperation-preventing closes interlock, is divided by circuit breaker, closing a floodgate is set to one interlock, reduce interlock and take volume, improve linkage reliability.
As depicted in figs. 1 and 2, a kind of breaker misoperation-preventing closes interlock, comprise bull stick 1, transmission mechanism 2, blocking lever 3, breaker open operation semiaxis buckle 4, mechanism's combined floodgate semiaxis 5, bull stick 1 device is on circuit breaker cabinet, on bull stick 1, device has knob 9, bull stick 1 is connected with blocking lever 3 by transmission mechanism 2, transmission mechanism 2 articulated mounting is on circuit breaker cabinet, transmission mechanism 2 is connected with bull stick 1 by hinge, transmission mechanism 2 is provided with long chute with the junction of blocking lever 3, blocking lever 3 is provided with connecting pin and is set in the long chute of transmission mechanism 2.The rotational movement transmission mechanism 2 of bull stick 1 rotates, and transmission mechanism 2 makes blocking lever 3, along long chute, upper and lower moving occur.
