Description
Technical field
A kind of overhaul of line breaker safety device of the utility model, belongs to the technical field of overhaul of line breaker safety device.
Background technology
Isolating switch refers to the contact maker that can close, carry and cut-off under normal loop and abnormal loop condition; isolating switch 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 isolating switch, only need at isolating switch both sides installing ground wire, but be about 1.3 meters due to the horizontal range between 10KV isolating switch 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.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is: provide the overhaul of line breaker safety guard that a kind of maintainer of preventing touches charged bus by mistake.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of overhaul of line breaker safety device, comprise the isolation protective net in deployed condition, described isolating and protecting is provided with range sensor, central controller and warning device on the net, and described range sensor is connected with central controller respectively with warning device.
Described isolation protective net is square, the surrounding of isolation protective net is respectively equipped with upper frame, underframe, left frame and correct frame, the volume brake lining be rotatably connected is provided with in described upper frame, for rolling the spool of brake lining and the guide driver for controlling reel action, described guide driver is connected with central controller, the gathering sill suitable with rolling up brake lining is equipped with in described left frame and correct frame, described isolation protective net is made up of insulating cord, described warning device is loudspeaker, described range sensor is arranged in left frame, described central controller is arranged on upper frame, described warning device is arranged on correct frame.
The utility model compared with prior art has following beneficial effect:
1, a kind of overhaul of line breaker safety device in the utility model, comprise: the isolation protective net in deployed condition, described isolating and protecting is provided with range sensor, central controller and warning device on the net, and described range sensor is connected with central controller respectively with warning device; When maintainer needs to overhaul isolating switch, if maintainer is in safety zone, without the need to the bus at its place is had a power failure, on channel-section steel between only isolation protective net need being placed on by the bus bar side disconnector of maintenance interval, 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 isolation protective net, 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, the volume brake lining of isolation protective net is packed up automatically; Simultaneously, distance between the health of range sensor Real-Time Monitoring maintainer and isolation protective net, when the health of maintainer gets close to isolation protective net so that reaches alarming value, range sensor transmits a signal to central controller, and central controller controls warning device carries out reporting to the police to point out staff not continue near isolation protective net in case there is Danger Electric shock risk again.
2, in the utility model, isolation protective net is square, the surrounding of isolation protective net is respectively equipped with upper frame, underframe (), left frame and correct frame, be provided with in upper frame be rotatably connected volume brake lining, for rolling the spool of brake lining and the guide driver for controlling reel action, guide driver is connected with central controller; Also insist on continuing when isolation protective net is close if maintainer receives alerting signal, range sensor sends a danger signal to central controller, central controller controls guide driver carries out work, guide driver controls reel action, volume brake lining in isolation protective net is put down automatically, stops that maintainer continues close to isolation protective net, ensure that staff avoids Danger Electric shock risk, reduce power failure range, ensure that power supply reliability.
