Abstract

The invention discloses a movable door isolation device used for a handcart-type switch cabinet and the handcart-type switch cabinet. The movable door isolation device comprises an insulating isolation plate provided with an upper connection window. The insulating isolation plate is provided with an insulating movable door capable of sliding along the vertical direction. The insulating movable door is provided with fixed supports. The fixed supports are provided with guiding grooves. The guiding grooves are internally provided with rolling wheels. Movable blocks are arranged between the fixed supports and the insulating isolation plate or the handcart-type switch cabinet. Guiding inclined surfaces used for pushing the insulating movable door to slide upwards are arranged on the lower sides of the movable blocks. One end of each movable wheel is connected with a wheel shaft of one rolling wheel, and the other end is hinged to the insulating isolation plate or the handcart-type switch cabinet. The movable door isolation device used for the handcart-type switch cabinet is arranged between a handcart chamber and a bus-bar room of the handcart-type switch cabinet. The movable door isolation device used for the handcart-type switch cabinet and the handcart-type switch cabinet have the advantages that the structure is simple, the machining is easy, the service lifetime is long, the operation is rapid and convenient, the labor is saved, the friction force is small, the needed force is smaller than that of a general hinge connection mode, and the application range is wide.

Description

technical field [0001] The invention relates to a DC power transmission and distribution switch cabinet, in particular to a valve isolation device for a handcart type switch cabinet and a handcart type switch cabinet. Background technique [0002] In the medium and low voltage electrical complete equipment system, the handcart type switchgear in the form of handcart type circuit breaker cabinet, handcart type DC switchgear or other handcart type medium and low voltage switchgear generally includes control room, handcart room, busbar room , and the handcart room is equipped with a trolley, which is convenient for pushing the DC fast circuit breaker into the working position and test position. However, since the circuit breaker has arc spray during the opening and closing process, how to solve the isolation between the handcart room and the main busbar room during the arc spraying process, especially the insulation between the main contact of the circuit breaker and the main b...
