Problems solved by technology

A variety of switchgear needs to be equipped with a variety of valve handcarts for daily maintenance and repair work, which has caused a lot of inconvenience to the operation and maintenance personnel
When the handcart is insufficient or the handcart is not suitable for the overhauled switchgear, and it is necessary to overhaul the opening valve in the circuit breaker room of the switchgear, the maintenance personnel cannot carry out the maintenance work normally
[0006] It is very important to develop a valve opening device with strong versatility, strong operability and high reliability that can open various types of valves, which is very important for solving the problems of many switchgear manufacturers, different types of valve driving vehicles and insufficient versatility. practical application value

Abstract

The invention discloses a switch cabinet valve opening and locking device comprising wheels which are installed on a chassis. An installing tube is fixedly arranged at the rear end of the chassis. A rotating handle is installed at the tail end of the installing tube. The installing tube is provided with a positioning pin which is driven to be inserted into a switch cabinet positioning hole through a driving device by the rotating handle. A control tube is fixedly arranged at the middle part of the installing tube. The control tube is internally provided with a rotating device of which the magnetic block is controlled to rotate by the rotating handle. The switch cabinet valve opening and locking device is reasonable in structure, reliable and firm in locking, easy to unlock, suitable for switch cabinets of different specifications, high in applicability, high in universality and convenient to operate.

Description

technical field [0001] The invention relates to an opening and locking device for a switch cabinet valve. Background technique [0002] With the continuous development of power equipment technology, 10kV mid-mounted switchgear is widely used in new construction, expansion and reconstruction of substations due to its compact structure, small footprint and convenient operation. [0003] For the daily maintenance and repair work of switchgear, when it is necessary to enter the interior of the circuit breaker room of the switch cabinet for maintenance work (such as dust removal and replacement of static contact boxes on the bus side and line side), circuit breaker handcart operation, hot standby, cold standby, maintenance State switching operation, as well as bus phase verification, electrical inspection and grounding work, it is necessary to open the static contact isolation baffle in the switchgear circuit breaker room. [0004] The device commonly used to open the static con...
