Description
Technical Field
The invention relates to the technical field of power distribution cabinets, in particular to a high-voltage middle-mounted switch cabinet with a pressure relief device.
Background
The five-prevention in the power system means that firstly, the circuit breaker is prevented from being opened and closed by mistake. And secondly, the isolating switch is prevented from being switched on or off under the load. And preventing the charged ground wire (grounding switch). Prevent the power transmission with the ground wire, namely prevent the circuit breaker (isolating switch) with the ground wire (grounding switch) from being closed. Prevent the false entering of the electrified interval.
The realization of the electric five-prevention function is one of the important measures for the safe production of electric power. With the continuous development of power grids and the continuous updating of the technology, the anti-misoperation device is continuously improved and perfected. The design principle of the anti-misoperation device is as follows: the high-voltage electrical equipment which may cause misoperation is provided with an anti-misoperation device and a corresponding anti-misoperation electrical locking loop.
The rear lower door of a 10KV high-voltage middle-placed switch cabinet on the market at present is locked by a door lock. The back lower door corresponds the cable chamber of the switch cabinet body, and operation and maintenance personnel need often open back lid door, overhauls or reconnects the cable in the cable chamber. However, at present, the power line basically adopts a "hand-in-hand" power supply mode, and when the circuit breaker in the centrally installed switchgear is located at a test position, the outgoing line side may still be supplied with power from other substations. Therefore, before the cables in the cable chamber are overhauled or reconnected, the outgoing line side needs to be ensured to be free of electricity.
1. Adopting an electricity testing handcart: before the cable in the cable chamber is overhauled or reconnected, the circuit breaker handcart is pulled out of the cabinet, and then the electricity testing handcart is pushed in to test whether voltage exists.
2. And (3) opening the door to test electricity: when the circuit breaker is in the test position, and electrified display device detects that the circuit is voltage-free, opens the cabinet door and verifies that there is no voltage.
However, the operation amount of the two modes is large, which is equivalent to twice of the power failure operation of a handcart without electricity testing, only the electricity testing and grounding operation of a bus is needed at present, and a special electricity testing handcart and a grounding handcart are needed. The second method is adopted by part of power departments, and the operation procedure is complex.
Therefore, a switch cabinet with a side shell convenient to disassemble and assemble is needed, and timely maintenance is facilitated when problems exist.
