Switch cabinet circuit breaker transfer handcart and application

Abstract

The invention provides a switch cabinet circuit breaker transfer handcart which comprises a frame and a contact cover curtain door opening and closing device, the contact cover curtain door opening and closing device comprises a push rod and transmission mechanisms installed on the left side and the right side of the frame, and a sleeve for driving a contact cover curtain door through eccentric hinging of connecting rods of the transmission mechanisms. And meanwhile, the lifting plate, the lifting mechanism, the corresponding buffer device and the corresponding self-locking device are arranged on the frame, so that the stability of the circuit breaker placement platform on the lifting plate and the accurate adjustment and self-locking functions of the handcart are realized.

Description

Technical field [0001] The present application relates to the field of high-pressure switching equipment, and in particular, there is a transitor and application of a switch cabinet circuit breaker. Background technique [0002] Hidden high-pressure switchgear, all called metal armor, transferred switch equipment, belonging to high voltage distribution devices, mainly used in power plants, substations, industrial and mining enterprises, etc., distribution and high voltage equipment start-stop control . It mainly includes several parts of the busbar unit A, the circuit breaker handbox B, cable chamber C, relay instrument chamber D, which are independent of the metal structure. figure 1 . [0003] In order to ensure the safety of operation, the person accidentally touchs the compact tumulator of the road control cabin B, and the front and lower contact cover doors are equipped with the front and lower contact cover. Under normal circumstances, the curtain is closed, covering the st...

AI Technical Summary

Problems solved by technology

[0004] During daily maintenance, the curtain door opening and closing device is prone to rebound after opening and closing, resulting in improper opening and closing of the curtain door, and some are driven by one side, which has poor reliability. The lock requires a large distance between the upper and lower contacts, which affects the layout size of the cabinet and other defects

[0005] And because the size of the circuit breaker in the switch cabinet is different, it needs to be equipped with transfer handcarts of different specifications, but the space in the switch room is limited. Adjust height limit, inconvenient to adjust
