Description
Technical field
The utility model relates to vacuum circuit breaker technical field, is specially a kind of novel isolation and grounding type interlinked mechanism.
Background technology
Vacuum circuit breaker is control appliance important in power system, and its running status has great impact to the reliability of power system. Existing vacuum circuit breaker adopts the three-phase segmentation kind of drive, this kind of drive connects often, and deviation accumulation is large, causes the synchronism of three-phase contact in the time of folding electric current to can not get ensureing, do not reach expection and cut-off target, severe patient can affect the concussion of power system; In addition, also cause overall structure volume excessive.
Utility model content
The purpose of this utility model is to provide a kind of novel isolation and the integrated mechanism of earthing mechanism formula, 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 isolation and the integrated mechanism of earthing mechanism formula, comprise installing plate, lever, connecting rod two, isolating switch and earthed switch, one end of described installing plate is provided with lever, lever is connected with connecting rod one by rotating shaft one, the other end of described connecting rod one is connected with connecting rod two, the middle part of connecting rod two is connected with connecting rod three by rotating shaft two, the other end of connecting rod two is connected with connecting rod four, the other end of connecting rod three is connected with isolating switch, the other end of connecting rod four is connected with earthed switch.
Preferably, one end of described isolating switch is tong-like structure, matches with the insulating contact on breaker.
Preferably, described earthed switch is provided with pointer grounding contact.
Preferably, between described connecting rod three and connecting rod two and isolating switch for being fixedly connected with.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple and reasonable for structure, safe and reliable, the design of employing integrated modular, the three-phase synchronous problem that has not only solved three isolated-earthed switch, also makes to install this switch cabinet size and greatly dwindles, and is convenient to install, easy to operate, there is good economic benefit.
