Description

Technical Field

[0001] The invention relates to the technical field of high-voltage switch cabinet maintenance, and in particular to a high-voltage switch cabinet trolley maintenance auxiliary device and a use method thereof. Background Art

[0002] A switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage room switch cabinets, with high-voltage busbars, such as power plants, etc. Some also have low-frequency load shedding to protect the main equipment. The main function of the switch cabinet is to open, control and protect electrical equipment during the power generation, transmission, distribution and energy conversion of the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors and various protective devices. There are many ways to classify switch cabinets. For example, according to the installation method of the circuit breaker, it can be divided into removable switch cabinets and fixed switch cabinets; or according to the different cabinet structures, it can be divided into open switch cabinets, metal-enclosed switch cabinets, and metal-enclosed armored switch cabinets; according to different voltage levels, it can be divided into high-voltage switch cabinets, medium-voltage switch cabinets and low-voltage switch cabinets. It is mainly suitable for various occasions such as power plants, substations, petrochemical industry, metallurgy and steel rolling, light industry and textile, factories and mines, residential areas, high-rise buildings, etc.

[0003] The trolley is the main component of the withdrawable switch cabinet. Generally, there are two types: PT trolley and switch (circuit breaker) trolley. The trolley is also called a small cart. Take the switch trolley as an example. When the switch is disconnected, it can be pulled out of the switch cabinet by hand after laying the guide rail for maintenance or replacement. It may be called a trolley because it can be pulled out by hand and its shape is similar to a trolley. The main components on the trolley are primary electrical equipment such as circuit breakers and mutual inductors. It has three positions in the switch cabinet: work / test / disconnect. The trolleys include circuit breaker trolleys, PT trolleys, isolation trolleys, fuse trolleys, metering trolleys, etc.

[0004] The trolley of the high-voltage switch cabinet needs to be regularly inspected and maintained to keep the trolley in a stable state. Since the trolley is heavy as a whole, a special body is needed to assist in moving the trolley so that the trolley can be moved to the maintenance platform. In the prior art, the auxiliary body of the trolley is very likely to tip over when the center of gravity is unstable, causing damage to the trolley and resulting in property loss. Summary of the invention

[0030] (III) Beneficial effects

[0031] Compared with the prior art, the present invention provides a high-voltage switch cabinet trolley maintenance auxiliary device and a method for using the same, which has the following beneficial effects:
