Abstract
The utility model provides a vacuum circuit breaker's blend switch, includes support body, motion arm, and the afterbody of motion arm articulates on the support body, and still including locating the switch piece that switch on the circuit, AND operation arm are connected, the switch piece can touch the switch after the motion arm direction removes and make the switch closure to keeping away from, and the switch piece removes back switch disconnection to the motion arm direction, be equipped with the slide rail on the support body, on the slide rail is located to switch piece cunning, be connected through the extension spring between the head of motion arm and the switch piece, still include the fixed carbon piece of locating on the circuit, the place ahead of carbon piece has a carbon -point, and the carbon -point is connected with the switch piece, and the carbon -point touches with the carbon piece mutually when the switch closure, and the carbon -point breaks away from with the carbon piece when the switch breaks off. The utility model relates to a blend switch, the break -make of circuit is controlled by switch and carbon -point, carbon piece jointly, has improved the security.
Description
Technical field
The utility model relates to a kind of switch of vacuum circuit-breaker.
Background technology
The general structure of the switch of vacuum circuit-breaker is: comprise support body, motion arm, the afterbody of motion arm is hinged on support body, the switch block also comprise the switch be located on circuit, being connected with motion arm, switch block is to can touching switch after moving away from motion arm direction and making switch close, and switch block moves rear switch and disconnects to motion arm direction.Its shortcoming also existed is: only have an ON-OFF control circuit break-make, and fail safe waits to improve.
Summary of the invention
In order to overcome the above-mentioned deficiency of the switch of existing vacuum circuit-breaker, the combination switch of the vacuum circuit-breaker that the utility model provides a kind of fail safe higher.
The technical scheme in the invention for solving the technical problem is: a kind of combination switch of vacuum circuit-breaker, comprise support body, motion arm, the afterbody of described motion arm is hinged on described support body, the switch block also comprise the switch be located on circuit, being connected with described motion arm, described switch block is to can touching switch after moving away from described motion arm direction and making switch close, and described switch block moves rear switch and disconnects to described motion arm direction;
Described support body is provided with slide rail, and described switch block is slidedly arranged on described slide rail, is connected between the head of described motion arm and described switch block by extension spring;
Also comprise the fixing carbon block be located on circuit, the front of described carbon block has a carbon-point, described carbon-point is connected with described switch block, and the carbon-point described in when described switch closes and described carbon block touch, and the carbon-point described in when described switch disconnects and described carbon block depart from.
Further, described support body is provided with guide cylinder, and described carbon-point is located in described guide cylinder.
Further, also comprise a connecting rod, one end of described connecting rod is hinged on described motion arm, and the other end of described connecting rod is hinged on described switch block.
In use, like the prior art, switch block is to can touching switch after moving away from motion arm direction and making switch close, and switch block moves rear switch and disconnects to motion arm direction for the utility model; The connecting and disconnecting of circuit simultaneously also need carbon-point to realize with coordinating of carbon block: carbon-point and carbon block touch thus the connection of realizing circuit when the switch is closed, and when described switch disconnects, carbon-point and carbon block depart from, and the dual disconnection of realizing circuit, guarantees safety.
The beneficial effects of the utility model are: the utility model is a kind of combination switch, and the break-make of circuit, by switch and carbon-point, carbon block co-controlling, improves fail safe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, a kind of combination switch of vacuum circuit-breaker, comprise support body 1, motion arm 2, the afterbody of described motion arm 2 is hinged on described support body 1, the switch block 3 also comprise the switch be located on circuit, being connected with described motion arm 2, described switch block 3 is to can touching switch after moving away from described motion arm 2 direction and making switch close, and described switch block 3 moves rear switch and disconnects to described motion arm 2 direction.
Described support body 1 is provided with slide rail 4, and described switch block 3 is slidedly arranged on described slide rail 4, is connected between the head of described motion arm 2 and described switch block 3 by extension spring 5.
Also comprise the fixing carbon block be located on circuit, the front of described carbon block has a carbon-point 6, described carbon-point 6 is connected with described switch block 3, and the carbon-point 6 described in when described switch closes touches with described carbon block, and the carbon-point 6 described in when described switch disconnects departs from described carbon block.
In use, like the prior art, switch block 3 is to can touching switch after moving away from motion arm 2 direction and making switch close, and switch block 3 moves rear switch and disconnects to motion arm 2 direction; The connecting and disconnecting of circuit simultaneously also need carbon-point 6 to realize with coordinating of carbon block: carbon-point 6 and carbon block touch thus the connection of realizing circuit when the switch is closed, and when described switch disconnects, carbon-point 6 and carbon block depart from, and the dual disconnection of realizing circuit, guarantees safety.Again closed after switch disconnects is realized by the pulling force of extension spring 5, switch block 3 under the effect of extension spring to can touching switch after moving away from motion arm 2 direction and making switch close.
In the present embodiment, described support body 1 is provided with guide cylinder 7, and described carbon-point 6 is located in described guide cylinder 7.Also comprise a connecting rod 8, one end of described connecting rod 8 is hinged on described motion arm 2, and the other end of described connecting rod 8 is hinged on described switch block 3, and connecting rod 8 can help switch block to reset.
