Emergency treatment device with dry-type transformer internal fire

Abstract

The invention relates to the technical field of transformers, and discloses an emergency treatment device with dry-type transformer internal fire. The device comprises a transformer body and fixing boxes arranged on the left side and the right side of the transformer body, an air cavity is formed in each fixing box, a weak acid storage box and a sodium bicarbonate storage box are arranged at the inner bottom of each air cavity, and guide rails are arranged on the outer walls of inner cavities of the two fixing boxes. According to the invention, the organizational structure of a traction rope and an iron sheet is arranged at the upper part in the device; after a fire occurs in the device, storage boxes at the bottoms of two sides of the device can be broke so as to mix to generate acid-baseneutralization reaction to release a large amount of carbon dioxide; and through the arrangement of the variable cross-section of an air outlet spray head, a large amount of carbon dioxide gas is instantaneously injected into the inner cavity of the device in a high-pressure and high-flow-speed state, so that air around the ignition point is thinned, the effect of cooling the periphery of the ignition point is achieved, and the fire extinguishing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an emergency treatment device for fire inside a dry-type transformer. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. [0003] When dry-type transformers are in use, due to the insulating rubber sleeves on the outside of the inner coils, the surface may age after long-term use, which may cause fires, and when the equipment is overloaded due to improper use, it may cause The temperature of the winding coil rises, and for a long time, it may cause the insulating rubber sleeve on the outer wall to catch fire, causing damage to other parts inside the transformer. In severe cases, it may cause the explosion of the transformer and cause a major safety accid...
