Abstract

The invention discloses a high-voltage switchgear of a single busbar system, which includes a base, a purification box and a controller. The top of the purification box is sequentially provided with an alarm, a temperature sensor, a first air quality sensor and a display. The air inlet end of the purification box is equipped with an air inlet protection net, and a wind collecting hood is installed inside the purification box inside the air inlet protection net, and a water tank is installed inside the purification box near the wind collecting hood, and one of the water tanks is An exhaust hood is installed in the side purification box, and a nano-plant fiber filter layer, a crystal activated carbon filter layer, a HEPA filter layer and a nano-photocatalyst decomposition filter layer are detachably installed in the side purification box at the opening of the exhaust hood. The present invention is provided with a series of structures so that the high-voltage switchgear can effectively prevent power failure and has extremely high safety.

Description

technical field [0001] The invention relates to the technical field of high-voltage switchgear, in particular to a high-voltage switchgear of a single busbar system. Background technique [0002] High-voltage switchgear refers to indoor and outdoor AC-DC switchgear operating in a power system with a voltage of 3kV and above and a frequency of 50Hz or below. It is mainly used in power systems (including power plants, substations, transmission and distribution lines, and industrial and mining enterprises, etc.) Users) control and protection, can not only put some power equipment or lines into or out of operation according to the operation needs of the power grid, but also quickly remove the faulty part from the power grid when the power equipment or lines fail, so as to ensure the safety of the fault-free part of the power grid Normal operation and the safety of equipment, operation and maintenance personnel. In the voltage distribution devices at all levels of power plants a...
