technical field

The invention belongs to the technical field of switchboards, and in particular relates to a multifunctional switchboard for power transmission and distribution lines and a method for using the same.

Background technique

The switchboard, also known as the power distribution cabinet, is a device for concentrating, switching, and distributing electric energy. The switchboard is generally composed of a cabinet, a switch (circuit breaker), a protection device, a monitoring device, an electric energy meter, and other secondary components. It is installed in a power station. ﹑For substations and power customers with large power consumption, the electric panel is usually composed of cabinets, switches, protection devices, electric energy meters, etc., and other secondary components.

Since the power distribution cabinet is generally installed outdoors, a large amount of heat is easily generated inside the power distribution cabinet during use. The power distribution cabinet is generally equipped with air inlets and air outlets, and natural wind is used to dissipate heat from the power distribution cabinet. When encountering rainy and snowy weather, rainwater is easy to enter the interior of the power distribution cabinet through the air inlet, which is likely to cause safety hazards to the electronic components inside the power distribution cabinet. When the winter is too cold, the temperature is too low to affect the work of the electronic components. As a result, the power equipment cannot be used normally, and the rainwater will cause the water level to be too high. A large amount of water entering the power distribution cabinet will cause leakage and affect life safety. Therefore, we propose a multifunctional switchboard for power transmission and distribution lines and its use method .
