Abstract
The invention relates to a disconnecting switch, in particular to a moving and static contact terminal apparatus of a disconnecting switch. The invention provides a technical scheme as follows: the moving and static contact terminal apparatus of the disconnecting switch comprises a moving contact terminal and a static contact terminal, wherein the moving contact terminal and the static contact terminal are respectively provided with a moving contact terminal contact and a static contact terminal contact, and the moving and static contact terminal apparatus is characterized in that the static contact terminal comprises a transverse edge, one end of the transverse edge is connected with a power connection terminal, the other end is provided with a vertical edge, the vertical edge is provided with the static contact terminal contact, the moving contact terminal is arranged at one side of the vertical edge of the static contact terminal, the moving contact terminal contact and the static contact terminal contact are correspondingly arranged, and the moving contact terminal is disposed below the moving contact terminal contact and connected with a conducting wire. By virtue of the technical scheme, the weaknesses in the prior art can be overcome, the contacts of the moving contact terminal and the static contact terminal closely contact each other when in closing, and an electric arc can be well guided to the position below the vertical edge of the static contact terminal when in opening.
Description
Technical field
The present invention relates to a kind of disconnecting switch, particularly relate to the dynamic/static contact device in disconnecting switch.
Background technology
Existing disconnecting switch structure is multiple contact disconnecting switch, and multiple moving contacts are under the direct drive of handle and connecting rod
Move along a straight line up and down, realize the separation of sound and contact, thus realizing closure and the disconnection of disconnecting switch, this product has one
Not enough a bit: one, the usage amount of noble metal is big, production cost is high, and because contact is many, reliability also reduces；2nd, after closing a floodgate
Between moving contact and the contact of static contact not closely, so easily cause current between contacts excessive, burn contact, affect product
Service life.
Content of the invention
The present invention overcomes the shortcomings of that prior art exists, there is provided during a kind of combined floodgate, the contact of dynamic/static contact is tight,
Can be very good during separating brake electric arc to be guided the dynamic and static contact apparatus of the new disconnecting switch below static contact vertical edge.
For achieving the above object, the technical scheme is that a kind of dynamic and static contact apparatus of disconnecting switch,
Include moving contact and static contact, described moving contact and static contact be respectively arranged with moving contact contact and static contact contact,
It is characterized in that: described static contact includes a horizontal edge, and one end of horizontal edge is connected with electrical terminals, the other end is provided with perpendicular
Side, vertical edge arranges static contact contact, and described moving contact is arranged on the side of static contact vertical edge, and moving contact contact is touched with static contact
Point is correspondingly arranged, and the lower section that described moving contact is located at moving contact contact is connected with wire.
By adopting such scheme, we can make moving contact and static contact can be very good to be close to one when closing a floodgate
Rise, be in particular in that electric current electric current when the horizontal edge of static contact flows to vertical edge downwards, then flows to moving contact from static contact contact
Contact, finally driven contact contact be downwardly towards guiding, make the vertical edge of static contact consistent with the sense of current on moving contact, so
Can form, between moving contact and static contact vertical edge, the electric power being harmonious, so that moving contact and static contact can be fine when closing a floodgate
Be close together, both positive and negative polarity is counter to be filled or is also same principle when the sense of current is contrary.
The further setting of the present invention is: the top of described static contact vertical edge forms striking to the bending setting of moving contact direction
Plate；Described static contact contact is one, and described moving contact contact is one, and described static contact contact is located in static contact vertical edge
Portion, described moving contact is extended positioned at the lower section of moving contact contact prolongation side, and wire is connected on prolongation side.
By adopting such scheme, make said structure more reasonable, more preferably, in addition the effect of setting run-on tab is can to effect
So that the electric arc that moving contact and static contact produce when separate is from run-on tab draws, prevents from electric arc, walking to burn out parts or stopping
Stagnant sustained combustion between moving contact and static contact and scaling loss sound contact, reduce service life.
The invention will be further described below in conjunction with the accompanying drawings.
Brief description
Fig. 1 is the structure chart of the embodiment of the present invention；
Fig. 2 is the static contact structure schematic diagram of the embodiment of the present invention；
Fig. 3 is embodiment of the present invention electric current principle structure chart.
Specific embodiment
As shown in Fig. 1 Fig. 3, a kind of dynamic and static contact apparatus of disconnecting switch, include moving contact 1 and static contact 2, institute
Moving contact contact 11 and static contact contact 21 are respectively arranged with the moving contact 1 stated and static contact 2, in embodiments of the present invention,
Described static contact 2 includes a horizontal edge 22, and one end of horizontal edge 22 is connected with electrical terminals 23, and the other end is provided with vertical edge
24, vertical edge 24 arranges static contact contact 21, described moving contact 1 is arranged on the side of static contact vertical edge 24, moving contact contact 11
It is correspondingly arranged with static contact contact 21, the lower section that described moving contact 1 is located at moving contact contact 11 is connected with wire 12.By adopting
Such scheme, we can make moving contact 1 and static contact 2 can be very good to be close together when closing a floodgate, and is in particular in electricity
Stream electric current when the horizontal edge 22 of static contact 2 flows to vertical edge 24 downwards, then flows to moving contact contact 11 from static contact contact 21,
Driven contact contact 11 is downwardly towards guiding 12 afterwards, makes the vertical edge 24 of static contact 2 consistent with the sense of current on moving contact 1, this
Can form, between sample moving contact 1 and static contact 2 vertical edge 24, the power being harmonious, so that moving contact 1 and static contact 2 are permissible when closing a floodgate
It is close together well, both positive and negative polarity is counter to be filled or the sense of current is also reversely same principle.
In embodiments of the present invention, the top 241 of described static contact vertical edge 24 bends setting formation to moving contact 1 direction and draws
Arc plate 241, the effect of setting run-on tab 241 is can to make moving contact 1 and electric arc that static contact 2 produces when separate is from run-on tab
Under 241 draw, prevent from walking to burn out parts on electric arc；Described static contact contact 21 is one, and described moving contact contact 11 is one,
Described static contact contact 21 is located at the middle part of static contact vertical edge 24, and the lower section that described moving contact 1 is located at moving contact contact 11 extends
It is provided with prolongation side 13, wire 12 is connected on the end extending side 13.
