Explosion-proof device for transformer bushing ascending flanged base

Abstract

The invention relates to an explosion-proof device for a transformer bushing ascending flanged base. The explosion-proof device for the transformer bushing ascending flanged base comprises a side facebushing ascending flanged base explosion-proof device and a top surface bushing ascending flanged base explosion-proof device, the side face bushing ascending flanged base explosion-proof device consists of explosion-proof stand columns, explosion-proof crossbeams which are fixed between the explosion-proof stand columns, an explosion-proof crossbeam prop which is arranged between the explosion-proof crossbeams, an ascending flanged base explosion-proof clamping connecting rod which is fixed on the explosion-proof prop, an ascending flanged base explosion-proof clamping transverse shoulder which is fixed on the ascending flanged base explosion-proof clamping connecting rod, an ascending flanged base explosion-proof clamping pressing arm which is fixed on the ascending flanged base explosion-proof clamping transverse shoulder and ascending flanged base explosion-proof ring arms which are fixed on the explosion-proof stand columns through ascending flanged base explosion-proof ring armconnecting rods; and the components and structures of the top surface bushing ascending flanged base explosion-proof device and the side face bushing ascending flanged base explosion-proof device arethe same. According to the explosion-proof device for the transformer bushing ascending flanged base, the problems of the damage and failure of a pipe network of a transformer fire extinguishing system, the damage of oil blocking facilities of a side face bushing transformer, the environmental pollution and operating personal injury caused by the explosion of the transformer bushing ascending flanged base can be prevented.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting facilities in substations, and in particular relates to an explosion-proof device for transformer bushing risers. Background technique [0002] For a long time, the fire protection design of the main transformer as the core equipment of the substation has mainly focused on the plane fire protection distance arrangement between the main transformers, as well as the arrangement of the transformer oil pool and emergency oil drainage system within the range of 1.0-1.5m in the shape of the transformer. Explosion-proof facilities for severe explosions of pipe risers. [0003] At 15:58 on October 4, 1995, a serious fire and explosion accident occurred in a 150,000 kVA transformer in a certain place in Jiangsu Province. 3 employees died, 12 were injured, and the direct property loss was 4.8 million yuan. On July 22, 2015, an explosion occurred in the high-voltage bushing and rising seat of the 1# m...

AI Technical Summary

Problems solved by technology

The transformer caught fire at 1:22 am on the 22nd. The fire brigade arrived at the substation fire scene at 2:25. At 5 o'clock in the morning, all the fires were extinguished. Afterwards, the transformer oil was basically burned out. After the fire brigade used fire truck water to extinguish the fire, a small amount of transformer oil was discharged outside the station through the road and site drainage system. pollute the surrounding environment

[0004] It can be seen from the above fire cases that when a serious explosion and fire occurs in a transformer, the most common thing is that the transformer bushing rises and explodes and breaks away from the transformer body, smashing the fire extinguishing system pipe network, causing the fire extinguishing system to fail, and even injuring the staff. Therefore, in order to ensure the transformer fire extinguishing system For normal use and to prevent personal injury, it is necessary to set up an explosion-proof device for transformer bushing risers
