Description

A lightning protection device for high voltage switch cabinet

Technical Field

The utility model relates to the technical field of high-voltage switch cabinets, in particular to a lightning protection device for high-voltage switch cabinets.

Background Art

The switch cabinet is an electrical equipment. 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-voltage load shedding for the maintenance of major 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 mainly include 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.

At present, the interior of the high-voltage switchgear is empty and has no structure. When workers need to install or repair the switchgear, the various electronic components inside are intricate. At the same time, when installing or repairing the electronic components at the bottom, workers need to squat and bend down to repair or replace the electronic components at the bottom. However, squatting and bending down for a long time can easily put a burden on the workers' spine, which not only reduces work efficiency but also affects the workers' physical and mental health.

When it rains, some clouds in the sky are positive and some are negative. When the two clouds meet, lightning will be emitted, and at the same time, a lot of heat will be released, causing the surrounding air to heat up and expand. The air that is instantly heated and expanded will push the surrounding air, causing strong explosive vibrations. When thunder strikes, it is possible to hit the high-voltage switchgear, causing irreversible damage to the switchgear.
