A mobile maintenance platform for high-voltage circuit breaker mechanism box

Abstract

The invention discloses a moving overhaul platform of a high-voltage breaker mechanism case, and relates to the field of transformer equipment. The moving overhaul platform comprises a moving device (1), an overhaul platform body (2) and a regulation and supporting device (3), wherein the overhaul platform body (2) is movably arranged on the moving device (1), and the regulation and supporting device (3) is detachably connected with the moving device (1) so that the moving device (1) can be regulated in the vertical height and fixedly supported. The moving overhaul platform can be flexibly moved into the breaker mechanism case, can be used for assembly detachment and installation, is suitable for being used for overhaul of assemblies large in mass and size, and is convenient to move due to the fact that the gravity center of the moving overhaul platform can be regulated at any time.

Description

technical field [0001] The invention relates to the field of substation equipment, in particular to a mobile maintenance platform for a mechanism box of a high-voltage circuit breaker. Background technique [0002] At present, in substations, the operating mechanisms of high-voltage circuit breakers generally adopt the form of spring mechanisms and hydraulic mechanisms. These mechanisms are now generally designed in a modular manner, consisting of various components, and compactly arranged in the circuit breaker mechanism box. When the circuit breaker mechanism breaks down, maintenance personnel are often required to replace the components in the mechanism box as a whole. Due to the high integration of components, complex functions, and tight connections between components, some components (such as disc spring modules) are large in mass and volume. And the bottom is hanging in the air. When replacing such components, maintenance personnel often need to fix and move the compo...

Problems solved by technology

When the circuit breaker mechanism breaks down, maintenance personnel are often required to replace the components in the mechanism box as a whole. Due to the high integration of components, complex functions, and tight connections between components, some components (such as disc spring modules) are large in mass and volume. And the bottom is suspended in the air. When replacing such components, maintenance personnel often need to fix and move the components by lifting them on their shoulders, and sometimes rely on tools such as forklifts.

When the above method is adopted, the disassembly and assembly of the components cannot be kept stable, and the disassembly and assembly work will become very inconvenient. At the same time, due to the high mass of the components, after disconnecting the components from other mechanisms, the components are very easy to fall and hurt people. When the forklift is on it, the center of gravity of the forklift will also be seriously shifted, which is prone to accidents such as overturning

Therefore, in the on-site maintenance work of the substation circuit breaker mechanism box, due to the lack of a suitable component disassembly platform, the maintenance work is time-consuming and laborious. At the same time, due to many unsafe factors, the personal safety of the maintenance personnel and the safety of the equipment cannot be effectively guaranteed.

[0003] For example, in the mechanism box of a 220kV high-voltage circuit breaker, the disc spring assembly is suspended inside. If the disc spring assembly needs to be removed, it needs to be removed from the connecting part of the crank arm of the switch transmission mechanism above. The maintenance personnel need to fix the disc spring first. , and then dismantle it, and then use a forklift to remove it. The whole operation is time-consuming and laborious, and there is a great potential safety hazard.
