Fireproof explosion-proof high-low voltage switch cabinet

Abstract

The invention provides a fire-proof and explosion-proof high-low voltage switch cabinet which comprises an electric power chamber, a water cooling chamber is arranged on the front surface of the electric power chamber, the right side face of the electric power chamber is fixedly connected with the bottom end of a longitudinal connecting plate through a first series of bolt sets, and the top end ofthe longitudinal connecting plate is fixedly connected with the right side face of the fire-proof and explosion-proof chamber through a second series of bolt sets. A high-voltage power supply is fixed to the left side face in the power chamber, a positive plate and a negative plate are arranged on the right side face of the high-voltage power supply, and the right side face of the positive plateis electrically connected with the left side face of a switch through a wire; the bottom end of the positive electricity leading piece is electrically connected with the upper side face of a pointer piece through a wire, and the pointer piece is fixed to the right end of the displacement rod. According to the technical scheme, the technical problems that in the prior art, the flexible output voltage adjusting capacity is not achieved, and water cooling, fire prevention, explosion prevention and the like cannot be achieved are effectively solved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a fireproof and explosion-proof high and low voltage switchgear. Background technique [0002] As the name suggests, the high and low voltage switchgear is a device for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers to low-voltage cabinets, and then to various power distribution boxes. It is nothing more than an electrical device that assembles some protective devices such as switch circuit breakers into one. The high and low voltage switchgear is an indispensable and very important position in the power supply system. Reasonable selection can minimize the loss of the power grid and improve the quality of the power grid. On the contrary, if it is selected or used improperly, it may cause many problems such as the increase of harmonics in the power supply...
