Description
Technical field
The present invention's outdoor 10KV overhaul of line breaker safety device, belongs to the technical field of overhaul of line breaker safety device.
Background technology
Circuit breaker refers to the contact maker that can close, carry and cut-off under normal loop and abnormal loop condition; circuit breaker not only can be used to distribute electric energy, infrequently start asynchronous motor; protection can also be carried out to power circuit and motor etc.; can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.
The 10KV interval great majority of the 35KV transformer station of electric company are all positioned at outdoor, according to the regulation of electric power safety working regulation, staff is when overhauling circuit breaker, only need at circuit breaker both sides installing earth connection, but be about 1.3 meters due to the horizontal range between 10KV circuit breaker and 10KV bus leading roll off the production line, make the maintainer be on framework stretch out one's hand at work tool for transmitting or material time, encounter charged bus leading to roll off the production line very easily by mistake, therefore, when overhauling 10KV wire-outgoing breaker, the 10KV bus at its place all must be had a power failure and can ensure safe distance, like this, virtually expand power failure range, reduce the reliability of power supply, add the complaint probability of user, reduce the service quality of power supply enterprise.
Summary of the invention
The present invention overcome prior art exist deficiency, technical problem to be solved is: provide a kind of can prevent maintainer touch by mistake charged bus, use time without the need to by bus have a power failure and the overhaul of line breaker safety guard be convenient for carrying.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: outdoor 10KV overhaul of line breaker safety device, comprise the first protector, described first protector comprises two cross one another built-in beams, two built-in beams at its infall by the first hinge together, described first protector also comprises square filter, four angles of square filter are flexibly connected with the two ends of two built-in beams by four jockeys, two built-in beams can be rotated around the first bearing pin and coincide together.
Described safety device also comprises the second protector, the structure of described second protector is identical with the structure of the first protector, in first protector, the two ends of two built-in beams are carried out hinged with the two ends of two built-in beams in the second protector each via second bearing pin accordingly, and two square filters form Double-protection net jointly; The slide block that described jockey comprises groove and can be free to slide in groove, described groove is arranged on built-in beam, and described slide block is fixedly connected with one of them angle of square filter, described slide block is also provided with the hook portion for hooking the second bearing pin; Described square filter is made up of fluorescent material; Described built-in beam is covered with the insulating barrier that one deck is made up of fluorescent material; Described built-in beam is made up of insulating material; Described square filter is made up of insulating cord.
The present invention compared with prior art has following beneficial effect:
1, the outdoor 10KV overhaul of line breaker safety device in the present invention, comprise: the first protector, first protector comprises two cross one another built-in beams, two built-in beams at its infall by the first hinge together, first protector also comprises square filter, four angles of square filter are flexibly connected with the two ends of two built-in beams by four jockeys, two built-in beams can be rotated around the first bearing pin and coincide together; When maintainer needs to overhaul circuit breaker, without the need to the bus at its place is had a power failure, only the safety device with square filter need be placed on by the channel-section steel between the bus bar side isolating switch at outdoor 10KV interval that overhauls, the maintainer be on framework stretch out one's hand at work tool for transmitting or material time, owing to being subject to the obstruction of square filter, charged bus leading can not be touched roll off the production line, avoid Danger Electric shock risk, reduce power failure range, ensure that power supply reliability, improve the good service image of power supply enterprise; In addition, coincide together owing to can rotate around the first bearing pin for two built-in beams of fixing square filter, after making service work, two built-in beams can coincide together by staff, whole safety device " receipts " is got up, carries very convenient.
2, the safety device in the present invention also comprises the second protector, the structure of the second protector is identical with the structure of the first protector, in first protector, the two ends of two built-in beams are carried out hinged with the two ends of two built-in beams in the second protector each via second bearing pin accordingly, two square filters form Double-protection net jointly, not only increase the framework of whole protector, and avoid maintainer better and touch charged bus.
3, the built-in beam in the present invention and square filter all can be made up of insulating material, ensure that the personal safety of staff, in addition, square filter is made up of fluorescent material, make whole safety device can be very clear when night uses, enhance efficiency of working at night, improve fail safe of working at night.
