Description

Anti-misoperation structure of switch cabinet

Technical Field

The utility model relates to a cubical switchboard technical field, in particular to cubical switchboard prevents mistake operation structure.

Background

The switch cabinet is an electrical device and mainly used for opening, closing, controlling and protecting the electrical device in the process of generating, transmitting, distributing and converting electric energy of an electric power system. The switch cabinet is simple in structure and comprises a cabinet body, and a vacuum circuit breaker, an isolating switch, a grounding switch, a cable and the like which are arranged inside the cabinet body. The isolating switch is used for completely isolating and cutting off the high-voltage end charge overhauling and maintaining end electricity, the grounding switch is used for reliably grounding the overhauling and maintaining end electricity, and the isolating switch and the grounding switch are both used for ensuring the safety of the overhauling and maintaining operation.

Wherein isolator, earthing switch, energy storage switch all insert through L shape or T shape handle and rotate and open and shut, and the cabinet door corresponds each switch department and all is provided with the operation hole that supplies the handle to pass. Before maintenance, power is cut off, after maintenance, power is transmitted, and power transmission and power cut-off operation need to be carried out according to a specified sequence. Wherein the power-off operation process is as follows: 1. firstly, anticlockwise rotating a vacuum opening knob to open the vacuum switch; 2. inserting the handle into the isolating switch operation hole, rotating anticlockwise, and separating the isolating switch; 3. and inserting the handle into the grounding switch operation hole, rotating clockwise and closing the grounding switch.

Chinese patent No. CN207743108U discloses a switch cabinet with an interlock structure between a lower door and an earthing switch and an isolating switch, which specifically comprises a switch cabinet body, wherein the switch cabinet body is also provided with an isolating switch and an earthing switch; an interlocking structure is further arranged in the switch cabinet body and comprises a switch baffle plate which can move up and down and is used for synchronously blocking the operation of the isolating switch and the grounding switch; the switch cabinet body still includes the lower door, is equipped with first lockhole on the lower door, interlocking structure still include with the first lockhole of linking to each other of switch baffle, first lockhole top just can be followed reciprocating of switch baffle and withdraw from or stretch into first lockhole.

The interlocking structure can simultaneously seal the isolating switch operation hole and the grounding switch operation hole by utilizing the vertically movable switch baffle plate, and is interlocked with the lower door through the first door lock rod. When the maintenance is powered off, the isolating switch and the grounding switch need to be operated, the first lower door lock rod is inserted into the first lock hole at the moment, the lower door is locked, and the switch baffle is staggered relative to the operation hole, so that the isolating switch and the grounding switch are in an operable state. After the disconnecting switch is opened and the grounding switch is closed, the switch baffle is moved upwards to enable the disconnecting switch and the grounding switch to be incapable of being operated, and at the moment, the lower door can be opened.

For preventing the switch baffle and the first locking lever of sliding down after the rebound from freely falling, first locking lever below is provided with locking lever baffle isotructure, and the locking lever baffle hinders its whereabouts after opening the sliding down, and then guarantees to overhaul unable isolator and earthing switch of operation in-process, and the security improves greatly. However, the following technical problems still exist: first door locking lever shifts up and needs up to pass through the staff, and the interval between two cabinet doors is little, and operating space is not enough, consequently blocks that isolator and earthing switch operate's process wastes time and energy, waits to improve.
