Anti-explosion fire extinguishing device for transformer

Abstract

The invention relates to the technical field of fire extinguishing devices for transformers, in particular to an anti-explosion fire extinguishing device for a transformer. The anti-explosion fire extinguishing device for the transformer comprises a fire extinguishing cabinet, an oil discharging pipe, a nitrogen charging pipe, the transformer, an oil collection pond and a control cabinet. A nitrogen charging opening and a discharged oil inlet are formed in the top end of the fire extinguishing cabinet. An anti-explosion pipe is arranged on the oil discharging pipe, a pressure adjusting controller is arranged at the tail end of the anti-explosion pipe, and a pressure adjusting anti-explosion membrane is arranged at the end, close to the pressure adjusting controller, of the anti-explosion pipe. According to the anti-explosion fire extinguishing device for the transformer, the fire extinguishing device is connected with the transformer to discharge high-temperature oil in the transformer timely. Nitrogen charged into the transformer can reduce the temperature of the oil in the transformer on the one hand to prevent the spread of the fire, and on the other hand, when the nitrogen is charged into the transformer and rises to the oil level, the air and the combustion oil level are isolated, and fire is extinguished rapidly. Meanwhile, the pressure adjusting controller and the pressure adjusting anti-explosion membrane are arranged, so that the anti-explosion performance is good.

Description

technical field [0001] The invention relates to the technical field of transformer fire extinguishing devices, in particular to a transformer explosion-proof fire extinguishing device. Background technique [0002] Transformer fires are generally caused by the destruction of internal insulation. The reasons are overload, operating overvoltage or lightning overvoltage, gradual degradation of insulation, drop in oil level, acidolysis of wet base oil, and damage to insulating bushings, causing arc energy to cause A sudden increase in oil temperature and pressure forced the top bushing or transformer body to rupture. Large quantities of burning oil can be gushed out over large areas, setting the entire power station or substation ablaze. The traditional transformer fire extinguishing method is to use water or carbon dioxide and other media to extinguish the fire. In this way, the fire extinguishing method must first solve the water source problem and limit the scope of use. Sec...

Problems solved by technology

The traditional transformer fire extinguishing method is to use water or carbon dioxide and other media to extinguish the fire. In this way, the fire extinguishing method must first solve the water source problem and limit the scope of use. Secondly, this method is only for the transformer to protect other equipment, but it cannot The protection of the transformer body cannot minimize the loss, and the use of water as the fire extinguishing medium will also cause damage to other equipment
