Abstract

The invention relates to a mutual inductor and an adsorber cover plate thereof. An explosion-proof channel is arranged on the adsorber cover plate; an explosion-proof cover is fixed on the cover plate, and accordingly, the explosion-proof structure of the mutual inductor is moved upwards to the side wall of the shell of the mutual inductor, so that the explosion-proof cover can be mounted when the mutual inductor is upright, and the mounting difficulty of the explosion-proof cover is reduced; furthermore, the explosion-proof channel does not need to be arranged on the base plate of the mutual inductor and the explosion-proof cover does not need to be fixed and packaged, so that the structure of the base plate of the mutual inductor is simplified; and the explosion-proof channel is less difficult to process and is lower in cost when arranged on the adsorber cover plate.

Description

technical field [0001] The invention relates to the technical field of power transformation equipment, in particular to a transformer, and also to an adsorbent frame used in the transformer. Background technique [0002] The function of the adsorber of the voltage transformer used for 220kV GIS (totally enclosed combined electrical appliances) is to absorb the moisture in the inner cavity of the transformer through its internal fixed packaging adsorbent, and the function of the explosion-proof cover on the voltage transformer is to prevent voltage When the transformer is abnormal, the internal pressure of the cavity increases, that is, when the pressure reaches a certain value, the explosion-proof cover cracks to release the pressure and protect the transformer. Currently, transformers (such as figure 1 As shown), the absorber cover plate 3 is fixed and packaged on the opening opened on the side wall of the housing 1, and the explosion-proof cover 5 is fixed and packaged on...
