Description

There is the high-voltage central-positioned switch cubicle of pressure relief device
Technical field
This utility model is related to a kind of equipment for power transmission and distribution, particularly a kind of high-voltage central-positioned switch with pressure relief device Cabinet.
Background technology
In power system five prevent referring to:1. prevent from dividing by mistake, close chopper.2. prevent on-load point, close disconnecting switch. 3. band cable address is prevented(Close)Earth lead(Earthed switch).4. anti-leukorrhagia stopping ground wire power transmission, that is, prevent line with ground(Ground connection is opened Close)Close chopper(Disconnecting switch).5. mistakenly entering charged chamber is prevented.
One of important measures for being implemented as electric power safety production of electric "five-proof" function.With constantly sending out for electrical network Exhibition, the continuous renewal of technology, error-proof device are updated and perfect.The design principle of error-proof device is:All it is possible to draw The high voltage electric equipment of maloperation is played, error-proof device all should be installed and anti-error electric blocking loop accordingly.
The rear Xiamen of 10KV high-voltage intermediate switch cabinets currently on the market, has door lock to lock.Xiamen corresponds to switch cabinet afterwards Cable vault, Operation and maintenance personnel need often to open after lid door, the cable in cable room is overhauled or is reconnected. However, at present power circuit adopt " hand in hand " power supply mode substantially, and middle-placed switch cabinet inner breaker positioned at testing position when, outlet Side is it is possible to power from other transformer stations.Therefore, before the cable in cable room being overhauled or reconnected, need Outgoing line side is guaranteed without electricity, at present, check system of the outgoing line side without electricity mainly has the following two kinds.
1. electricity-testing handcart is adopted:Before cable in cable room is overhauled or reconnected, circuit breaker cart is drawn Offer for sale outer, then push electricity-testing handcart, checked whether voltage.
2. enabling electrical verification:When chopper is in testing position, and charged display device detects circuit no-voltage, opens cabinet Door identifies true no-voltage.
However, above two mode operational ton is very big, equivalent to the twice without electricity-testing handcart power failure operation, now only Bus electrical verification and ground connection operation, but also special electricity-testing handcart and earth handcart need to be adopted.Method two is by some electrical power department Using operation sequence is more complicated.
