Electronic inversion welding cutting power supply system apparatus

Abstract

The invention discloses an electronic inversion welding cutting power supply system apparatus. The electronic inversion welding cutting power supply system apparatus comprises a power supply box. Theinner wall of the power supply box is connected with a power supply body. Heat dissipation ports are formed in the two opposite side walls of the power supply box respectively, and the inner walls ofthe heat dissipation ports are rotatably connected with a plurality of rotating shafts which are arranged in parallel; and the rotating shafts are sleeved with grid plates and gears respectively. Theelectronic inversion welding cutting power supply system apparatus has a simple structure. When open flame occurs in the power supply box due to short circuit, the internal temperature of the power supply box rises; by virtue of a heat conducting effect of heat absorbing sheets, a heat absorbing plate and a heat absorbing box, an expansion airbag is thermally expanded, and two sliding rods are driven to move oppositely. A hook is separated from a bayonet in the lower end of each rack. Under the resilience action of a first spring, each rack moves upward, then the rack is meshed with the corresponding gear to drive the corresponding rotating shaft to rotate, and the rotating shaft drives the corresponding grid plate to a vertical position so as to seal the corresponding heat dissipation port, in order to prevent the open fire from appearing outside the power supply box and to avoid expansion of the fire range. At the same time, by virtue of the grid plates, the amount of air flowing into the power supply box can be reduced and fire behavior can be suppressed.

Description

technical field [0001] The invention relates to the field of power supply technology, in particular to an electronic inverter welding and cutting power supply system device. Background technique [0002] A power supply is a device that provides power to electronic equipment, also known as a power supply, which provides the electrical energy required by all components in the computer. The size of the power supply, whether the current and voltage are stable will directly affect the working performance and service life of the computer; the existing power supply generally lacks protection measures during use. Once a fire is caused by a short circuit, it is difficult for the power box to take active fire prevention measures. , to curb the occurrence of fire. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an electronic inverter welding and cutting power supply system device. [0004] In order t...
