Oil-immersed three-phase transformer

Abstract

The invention discloses an oil-immersed three-phase transformer which comprises a transformer body, two extending pieces, two blocking assemblies and two fire extinguishing assemblies. The two extending pieces are correspondingly installed on the two sides of the lower surface of the transformer body. The two fire extinguishing assemblies are installed on the two sides of the upper surface of the transformer body in parallel, and the output ends of the two fire extinguishing assemblies face the transformer body. The two blocking assemblies are correspondingly installed on one sides of the fire extinguishing assemblies, and the blocking assemblies can cover the two side walls of the transformer body. The fire extinguishing assemblies are installed on the two sides of the upper surface of the transformer body, the wiring position of the transformer body is fully covered, and the problem that fire is transmitted along wires is avoided. The two side walls of the transformer body are covered with fireproof cloth for fire prevention under the assistance of the blocking assemblies, rapid spreading of fire on the transformer body is avoided, meanwhile, the transformer body can be blocked, gas flowing is reduced, and the fire extinguishing period is shortened.

Description

technical field [0001] The invention relates to the technical field related to transformers, in particular to an oil-immersed three-phase transformer. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The most basic form of a transformer includes two sets of coils wound with wires, and they are combined together in an inductive manner. With the rapid development of electric power in our country, A large number of transformers are required for power transmission, but when the existing transformers are in use, it is very easy to catch fire at the wiring of the transformers. At the same time, the traditional transformers do not have the effect of automatic fire extinguishing, and cannot extinguish and alleviate the fire. Increased the damage rate of the transformer. [0003] The existing technology has the following disadvantages: when the existing transformer is in use, it is very easy to cat...
