Embodiment 1

[0038] This embodiment provides an automatic locking device for a transformer breather, which is a connecting part between an oil conservator and a moisture absorber, such as figure 1 as shown, figure 1 It is a schematic diagram of the mechanism and principle of the automatic locking device for the transformer respirator of the present invention.

[0039] Among them: the outer wall 1 of the respirator locking device is connected with the lower flange 7 of the breathing pipeline of the oil conservator, specifically, the bolt passes through the upper screw hole 101 on the outer wall 1 of the respirator locking device and the lower flange 7 of the breathing pipeline of the oil conservator Tighten the connection.

[0040] The upper and lower sides of the outer wall 1 of the respirator locking device are provided with a plurality of screw holes, the upper part is an upper screw hole, and the lower part is a lower screw hole.

[0041] The outer wall 1 of the locking device of the ...

Abstract

The invention belongs to the technical field of electric power emergency protection devices, particularly relates to an automatic locking device of a transformer respirator, and particularly relates to a transformer fire protection device. The device comprises an oil conservator and a moisture absorber, the upper portion of the outer wall of a respirator locking device is connected with a lower flange of a breathing pipeline of the oil conservator, and the lower portion of the outer wall of the respirator locking device is connected with an upper flange of the moisture absorber; an inner blocking wall is arranged in the oil conservator breathing pipeline and connected with an action baffle, and the action baffle is connected with a limiting pull rod on the outer wall of the respirator locking device. The transformer oil conservator can inhibit the overflow degree of insulating oil in the oil conservator when a fire occurs in the transformer body. The device has the advantages of beingeasy to recover after action, reliable in sealing after action and the like, is wide in application range, low in transformation cost and easy to replace, can ensure the reliability and the sealing performance before action, the instantaneity of action when a signal is received and the easy recovery after action, and is more reliable and stable in operation.

Description

technical field [0001] The invention belongs to the technical field of electric power emergency protection devices, in particular to an automatic locking device for a transformer respirator, in particular to a transformer fire protection device. Background technique [0002] During the operation of oil-immersed power transformers, due to adverse environmental influences, excessive equipment loads, aging equipment, internal insulation damage, insufficient insulating oil, or poor fittings and overheating, the internal temperature of the transformer is too high and explosions and fires occur. Therefore, limiting the fire situation within the controllable range can reduce the impact on other live equipment around the sudden fault transformer, and reduce the losses caused by fire accidents. [0003] When an oil-immersed transformer explodes due to an accident, the location of the rupture is usually the explosion-proof valve of the transformer or the root of the bushing, and the c...
