Abstract

The invention discloses an arc extinguishing element used for a switch cabinet. The arc extinguishing element comprises a first cavity and a second cavity, an annular conductive body, a resistor and two switch contacts are arranged inside the first cavity, the annular conductive body is provided with an input end and an output end, the switch contacts are arranged at the inlet end of the first cavity and the inlet end of the second cavity respectively, the input end of the annular conductive body is connected with the switch contacts, the resistor is arranged at the output end of the annular conductive body, the first cavity is connected with the second cavity, and the interior of the second cavity is in a vacuum environment. The arc extinguishing element used for the switch cabinet is provided with the first cavity and the second cavity, arcs are consumed completely through the resistor in the first cavity, the vacuum arc-extinguishing environment is formed in the second cavity, underthe dual effects, it is ensured that the high-intensity arcs in the switch cabinet are completely extinguished without exploding or vibrating or other phenomena, and the using safety and stability ofthe switch cabinet are guaranteed.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an arc extinguishing element for a switch cabinet. Background technique [0002] In the switchgear, due to the high temperature and the interference of multiple circuit components, a large arc will be generated in the switchgear. Especially for high-voltage switchgear, in order to ensure the stable operation of the switchgear, arc extinguishing treatment is usually required. An arc extinguishing chamber is usually set in the switchgear, and the arc is quickly disappeared by using gas or oil or using a vacuum environment. This makes the arc extinguishing process more intense, and is prone to blasting, vibration, etc., and often has the problem of incomplete arc extinguishing. Contents of the invention [0003] The main technical problem to be solved by the invention is: the arc extinguishing treatment of the existing switchgear is incomplete or easy to generate blastin...
