Residential power distribution project: to provide stable power supply for residential communities.Industrial and commercial power distribution projects: to ensure the power needs of commercial facilities such as shopping malls and office buildings.Distributed photovoltaic projects in urban or residential areas: provide power access and conversion for photovoltaic power generation systems.Municipal engineering design: such as road lighting, traffic lights and other facilities of power supply.Other public facilities: such as schools, hospitals, airports, stations, tourist attractions, etc., to provide reliable power protection.

Power cabinets are widely used in various industrial and commercial environments, such as production lines, motors, transformers and other industrial fields, as well as shopping malls, office buildings, hotels and other commercial buildings. It is one of the basic equipment to ensure the normal operation of all kinds of electrical equipment.

The internal structure of the power cabinet usually includes a power compartment, a function compartment and a bus compartment. The power compartment is used to connect the main power supply, and the function compartment is equipped with various control components and protection devices, such as circuit breakers, contactors, thermal relays, etc. The busbar room is used to connect each branch power supply to realize the distribution of electric energy.

The maintenance of high voltage switchgear mainly includes regular inspection, cleaning, fastening and lubrication. In addition, it is necessary to test and verify the electrical performance of the equipment to ensure that it is in good working condition. During maintenance, strictly follow the operation rules to ensure the safety of operators.

The working principle of high voltage switchgear is to connect and disconnect the circuit by controlling the opening and closing of the switch. When the circuit needs to be broken, the electric mechanism controls the opening and closing of the switch through the gear reducer, the transmission mechanism, etc., so that the circuit is disconnected; When the circuit needs to be connected, the electric mechanism makes the circuit connected by controlling the closure of the switch.
