Fire-proof transformer

Abstract

The invention discloses a fire-proof transformer, and relates to the technical field of electrical equipment. In use, a transformer body of the fire-proof transformer can reduce high-voltage electricity of a power grid into electricity with 6000 v or 380 v voltage which can be directly used, and power is supplied to electric equipment. When the transformer body is on fire and burns, the transformer body can generate high temperature, the temperature is transmitted to a fusing rod through a base and upright columns, and the fusing rod can be fused due to the low fusing point. At this moment, anextinguishment shield can fall down from the upright columns, the transformer body is covered with the extinguishment shield, an magnetic attraction ring can tightly attract the stainless steel base,the on-fire transformer body is isolated from the outside air through the extinguishment shield, the effect that the fire is quickly put out the first time is achieved, and the fire-proof performanceis good.

Description

Technical field [0001] The invention relates to the field of electrical equipment, in particular to a fire-proof transformer. Background technique [0002] Power transformers are the main equipment for power transmission and distribution in power systems. The main function of the power transformer is to reduce the high-voltage power of the grid to 6000v or 380v that can be used directly to supply power to the electrical equipment. If an overload or short circuit occurs inside the transformer, the insulating material or insulating oil will decompose due to high temperature or electric sparks, expand and even vaporize, causing the internal pressure of the transformer to increase sharply, which may cause the transformer shell to explode and a large amount of insulating oil will be sprayed and burned. Flow will further amplify the fire hazard. The existing transformer design is relatively traditional, and it is not enough to prevent fire and extinguishing. As a result, the transfor...

AI Technical Summary

Problems solved by technology

The existing transformer design is relatively traditional, and the prevention of fire prevention and fire extinguishing is not enough. As a result, the transformer can only use external force to extinguish the fire, but cannot effectively extinguish the fire itself when a fire occurs, and cannot effectively control the fire at the first time. The fire performance is not good.
