Complete set of power switch equipment

Abstract

The invention discloses a complete set of power switch equipment, which comprises a cavity with a forward opening in a shell, the left wall of the cavity is communicated with the left surface of the shell through a channel with a fan, the opening of the cavity is rotatably connected with a sealing door, the sealing door is provided with a handle groove, the top wall of the cavity is fixedly provided with a heat collection bin, a heat collection cavity with a downward opening is formed in the heat collection bin, and an early warning device capable of preventing the switch from being overheated is arranged in the heat collection cavity. Bidirectional arc extinguishing equipment is arranged at the on-off position of the switch equipment, the arc extinguishing efficiency of the arc is improved through cutting and cooling spraying of the arc, arc extinguishing can be carried out on the switch equipment at the moment of switching on and switching off a circuit, a fire disaster is prevented, and a better fire disaster prevention effect is achieved through arrangement of thermal deformation metal. When the temperature of the switch equipment reaches an early warning temperature, all channels are closed to isolate air, so that the box has insufficient oxygen to burn, and the purpose of completely eradicating fire disasters is achieved.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a complete set of power switching equipment. Background technique [0002] Switchgear (power distribution equipment) is a general term for high-voltage power distribution cabinets, generators, transformers, power lines, circuit breakers, low-voltage switchgear, switchboards, switch boxes, control boxes and other power distribution equipment in the power system. [0003] The traditional switchgear will generate a large amount of arc when it is switched on and off, and it may cause fire or explosion if it is not handled properly. arc, causing sudden accidents on the other side, there are unnecessary hidden dangers, and it has an impact on the efficiency of arc extinguishing. [0004] Traditional switchgear fires in the event of overheating, which has a huge impact on the equipment, and fire prevention devices in traditional switchgear often have delays and are not very sen...
