Special circuit breaker handcart for removable alternating-current metal enclosed switch cabinet

Abstract

The invention relates to a special circuit breaker handcart for a removable alternating-current metal enclosed switch cabinet. The special circuit breaker handcart comprises a bracket, a top plate and a plurality of casters; wherein the top end of the bracket is fixedly connected with a square support plate, and four top corners of the square support plate are connected with the top plate respectively through a height regulating device; the side of the top plate, which is contacted with a circuit breaker cabinet, is fixedly connected with two contact handles through a positioning plate, and the distance between the two contact handles is arranged corresponding to the distance between two contact holes in the lower part of the circuit breaker cabinet; and the positioning plate is also provided with a clamping claw, and the clamping claw is connected with an operating handle opposite to the top plate and the circuit breaker cabinet through a connecting rod. The special circuit breaker handcart can be used conveniently, safely and reliably, and the connecting wire of the two contact handles of the circuit breaker handcart can be made parallel to the connecting wire of the two contact holes in the lower part of the circuit breaker cabinet through adjusting the regulating wheels according to the actual working environment so as to facilitate overhaul of a circuit breaker in the removable alternating-current metal enclosed switch cabinet.

Description

technical field [0001] The invention relates to a matching switch of a power system, in particular to a circuit breaker handcart for a removable AC metal-enclosed switchgear. Background technique [0002] The removable AC metal-enclosed switchgear is a switchgear used in the single-bus system segmental power system. It is used for receiving and distributing electric energy in power plants, substations, industrial and mining enterprises, and high-rise buildings. It is an indoor metal-enclosed switchgear for real-time control, protection and detection of circuits. The removable AC metal-enclosed switchgear is a compartmental structure equipment, including a cabinet body and a handcart. The cabinet body is assembled from a number of small cabinet rooms that are bent and welded by section steel and steel plates; each handcart is connected to a corresponding small cabinet. Corresponding to the cabinet room, the handcart is used to open and close the pick-and-place dial card in t...

Problems solved by technology

However, due to the existence of the cable trench, the ground is uneven, and it cannot be reliably ensured that the tentacles on the handcart correspond to the contact holes under the circuit breaker cabinet, so it is impossible to open the latch in the circuit breaker cabinet and drag the circuit breaker. cause great inconvenience

In addition, when the switch in the circuit breaker cabinet is turned on, when dragging the circuit breaker, usually by directly pulling the handle on the circuit breaker, the circuit breaker is directly dragged to the top plate of the handcart, which is time-consuming and laborious; There is a separate structure between the trolley and the circuit breaker cabinet, so if you are not careful in the process of dragging the circuit breaker, the circuit breaker handcart will be separated from the switch cabinet, causing the circuit breaker to fall, which poses a great safety hazard
