Description
Technical field
The utility model relates to vacuum circuit breaker technical field, is specially one novel five anti-chain.
Background technology
At present, for guaranteeing personal safety, should possess to high voltage electric equipment the mistake of preventing and divide, close breaker, prevent that on-load from dividing, closing isolating switch, prevent from being with cable address (closing) earth connection (earthed switch), prevent from being with ground wire power transmission, prevent five kinds of anti-error functions of mistakenly entering charged chamber, and this five anti-be most important part in electric power safety.
Most employing is now stretched out a block and is blocked by force breaker in the time that earthed switch closes a floodgate on switch cubicle, does not allow the mode of its introducing solve. This mode is very high to the requirement of block intensity, if the situation that breaker is introduced by force may appear in insufficient strength. In addition, normally introduce strength when larger when breaker, bad judgement breaker is in normal introducing state or has been blocked by force state, and operating personnel are judged to whether the strength size of introducing breaker requires very high normally.
Utility model content
The purpose of this utility model is to provide one novel five anti-chain, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of novel five is anti-chain, comprise lever, rotating shaft one, connecting axle and junction panel, described lever is connected with connecting rod one by rotating shaft one, connecting rod one is connected with gangbar, and the other end of connecting rod one is connected with rotating shaft two with Timing Belt by connecting axle, and rotating shaft two is provided with dop, junction panel is fixed on installing plate by alignment pin, and the top of junction panel is provided with connector.
Preferably, the surface of described Timing Belt is provided with rectangular teeth, and two ends are connected with rotating shaft two with connecting axle respectively.
Preferably, one end of described dop is fixedly connected with rotating shaft two, openend is established inverted " L " shape block tongue.
Preferably, described connector be provided with dop on the latch that matches of block tongue.
Preferably, described junction panel is provided with slideway.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple and reasonable for structure, safe and reliable, make breaker, isolating switch, earthed switch and front rear cabinet door reach the reliability of height, and greatly reduce the labour intensity of installing, and greatly improved the reliability of product.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
In figure: 1, lever; 2, rotating shaft one; 3, connecting rod one; 4, connecting axle; 5, Timing Belt; 6, dop; 7, rotating shaft two; 8, connector; 9, junction panel; 10, gangbar; 11, alignment pin; 12, slideway.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of novel five is anti-chain, comprise lever 1, rotating shaft 1, connecting axle 4 and junction panel 9, it is characterized in that: described lever 1 is connected with connecting rod 1 by rotating shaft 1, connecting rod 1 is connected with gangbar 10, the other end of connecting rod 1 is connected with rotating shaft 27 with Timing Belt 5 by connecting axle 4, rotating shaft 27 is provided with dop 6, junction panel 9 is fixed on installing plate by alignment pin 11, and the top of junction panel 9 is provided with connector 8; The surface of described Timing Belt 5 is provided with rectangular teeth, and two ends are connected with rotating shaft 27 with connecting axle 4 respectively; One end of described dop 6 is fixedly connected with rotating shaft 27, openend is established inverted " L " shape block tongue; Described connector 8 be provided with dop 6 on the latch that matches of block tongue; Described junction panel 9 is provided with slideway 12.
Operation principle: need in circuit to overhaul while disconnection, lever 1 is rotated counterclockwise, drivening rod 1 rotates counterclockwise, and by gangbar 10, isolating switch and earthed switch is moved, and drives rotating shaft 27 to rotate counterclockwise by Timing Belt 5 simultaneously, dop 6 is moved right, now, junction panel 6 is pulled upwardly, carries out interlock by connector 8 with the block tongue on dop 6 and fix, prevent thus the movement of gangbar 10, guarantee safety.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
