Abstract
The utility model relates to a novel interlock comprising a breaker closing button (1), a breaker opening button (2), a breaker operating panel guide rail (3), a breaker operating panel (4), a linkage rod (5), and an isolating switch operating shaft (6). When an isolating switch performs rotational motion in a brake opening and closing process, the novel interlock drives the linkage rod (5) and the breaker operating panel (4) to perform rail sliding motion by using a guide rail sliding principle so as to achieve an anti-maloperation interlocking function between the breaker and the isolating switch.
Description
Technical field
The utility model relates to a kind of novel interlocking, is applicable to the design of the interlocking between the circuit breaker and isolating switch in the high voltage switchgear.
Background technology
Interlocking between circuit breaker and isolating switch in the present existing high voltage switchgear is by independently operating mechanism operation, and the interlocking between them is complicated, and it is bigger to take up room.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of novel interlocking is provided, the design principle novelty, simple in structure, volume is little.To achieve the above object of the invention, the utility model is by the following technical solutions:
A kind of novel interlocking comprises: breaker closing button (1), breaker open operation button (2), breaker operator panel guide (3), breaker operator plate (4), gangbar (5), isolator operation axle (6); When the isolating switch conducting rod is in half point and narrows state, gangbar (5) drives breaker operator plate (4) motion to the left or to the right on breaker operator panel guide (3), movement position is in the middle of slotted hole, cause breaker closing button (1) or breaker open operation button (2) to press, prevent that circuit breaker from carrying out the misoperation of separating brake or combined floodgate.A kind of novel interlocking when the isolating switch on/off switch rotates, utilizes the guide rail principle of confounding, realizes anti-misoperation interlock between circuit breaker and the isolating switch.
Compared with prior art, the beneficial effects of the utility model are: the design principle novelty, simple in structure, volume is little.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is front view of the present utility model.
Embodiment
Below, describe preferred embodiment of the present utility model in detail with reference to accompanying drawing.Need to prove before this, employed term or word can not limited interpretation be the implication in common implication or the dictionary in this specification and claims book, and should be based in order to illustrate that in the best way principle that its practical novel inventor can suitably define the concept of term is interpreted as meeting implication and the concept of the utility model technological thought.Thereupon, the structure of representing in the embodiment that this specification is put down in writing and the accompanying drawing is one of the utility model most preferred embodiment, can not represent technological thought of the present utility model fully, therefore should be understood that for the utility model, to have various equivalents and the variation that to replace.
As shown in the figure, a kind of mechanical interlocks of the present utility model comprises: breaker closing button (1), breaker open operation button (2), breaker operator panel guide (3), breaker operator plate (4), gangbar (5), isolator operation axle (6).
Described breaker closing button (1) or breaker open operation button (2), when the isolating switch conducting rod is in half point and narrows state, isolator operation axle (6) does not have the success of operation on/off switch, gangbar (5) drives breaker operator plate (4) motion to the left or to the right on breaker operator panel guide (3), movement position is in the middle of slotted hole, cause breaker closing button (1) or breaker open operation button (2) to press, prevent that circuit breaker from carrying out the misoperation of separating brake or combined floodgate.
It should be noted that, although the present invention is described and illustrates with reference to embodiment, but and do not mean that the present invention is limited to the execution mode of these descriptions, those skilled in the art can therefrom derive many different variants, and they all will be covered in the true spirit and scope of claim of the present invention.
Claims (1)
1. a novel interlocking is characterized in that, comprising: breaker closing button (1), breaker open operation button (2), breaker operator panel guide (3), breaker operator plate (4), gangbar (5), isolator operation axle (6); When the isolating switch conducting rod is in half point and narrows state, gangbar (5) drives breaker operator plate (4) motion to the left or to the right on breaker operator panel guide (3), movement position is in the middle of slotted hole, cause breaker closing button (1) or breaker open operation button (2) to press, prevent that circuit breaker from carrying out the misoperation of separating brake or combined floodgate.
