GGJ low-voltage reactive power compensation cabinet

Abstract

The invention belongs to the technical field of power equipment and discloses a GGJ low-voltage reactive power compensation cabinet. The GGJ low-voltage reactive power compensation cabinet comprises acabinet body, feedback sealed air bags, and a gas exchange fire extinguishing mechanism. The front side of the cabinet body is hinged with a cabinet door, the upper side of the right wall of the cabinet body is provided with five strip-shaped heat dissipation holes which are orderly arranged from the top to bottom, a right side face of the cabinet body is equipped with a radiating fan corresponding to the strip-shaped heat dissipation holes, the feedback sealed air bags are bonded to gaps at inner sides of top walls of the strip-shaped heat dissipation holes, and the gas exchange fire extinguishing mechanism is arranged outside the cabinet body. According to the GGJ low-voltage reactive power compensation cabinet, by setting a gas exchange mechanism, the quick reaction is performed by using the change of the temperature in the cabinet body, the cabinet body is filled with nitrogen gas, at the same time, fan blades are driven to rotate by using the linkage between a ring and a gas supply shell, a phenomenon that the density of the nitrogen gas is lower than that of air and the nitrogen gas floats on the upper layer of the cabinet body is used, the fan blades quickly extract the airfrom the cabinet body, the cabinet body is quickly filled with the nitrogen gas, and the convection is formed by the filling of the nitrogen gas and the discharge of the air.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a GGJ low-voltage reactive power compensation cabinet. Background technique [0002] GGJ low-voltage reactive power compensation cabinet is mainly used in substations, factories, industrial and mining enterprises, large power plants, petroleum, chemical enterprises, large steel mills, high-rise building power centers, reactive power compensation and other occasions. [0003] For the fire treatment of the GGJ low-voltage reactive power compensation cabinet, based on the technology of fire alarm and circuit power failure, it is commonly used to use sensor feedback to extinguish the fire, or use carbon dioxide to create an oxygen-free environment, but the problem is that carbon dioxide fire extinguishing needs to reach The fire extinguishing concentration, the carbon dioxide fire extinguishing process will be accompanied by the flow of air in the cabinet. The carbon dioxi...

Problems solved by technology

[0003] For the fire treatment of the GGJ low-voltage reactive power compensation cabinet, based on the technology of fire alarm and circuit power failure, it is commonly used to use sensor feedback to extinguish the fire, or use carbon dioxide to create an oxygen-free environment, but the problem is that carbon dioxide fire extinguishing needs to reach The fire extinguishing concentration, the carbon dioxide fire extinguishing process will be accompanied by the flow of air in the cabinet. The carbon dioxide and air will mix and flow through the fire place, and the fire cannot be extinguished in time. The spread of the fire will inevitably damage more electronic devices and cause greater losses. Forming an oxygen-free environment in the cabinet to prevent the spread of fire is a problem that continues to be solved
