Embodiment Construction
[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0019] The advantage of the oil-immersed transformer respirator with a cutoff plate of the present invention is: a flow cutoff plate is arranged on the pull rod, and a vent hole is arranged on the bottom plate, so that the distance of the air flowing through the respirator through the desiccant is relatively large, Not only can make full use of the desiccant in the respirator, but also can fully absorb the moisture in the air, and the filtering effect is better; by turning the pull rod, the desiccant close to the air outlet pipe can be pushed to the air intake pipe, further improving the desiccant utilization rate.

The invention discloses an oil immersed transformer breather with an isolation plate. The oil immersed transformer breather comprises a top cover, a transparent cover cylinder, a bottom plate and an oil groove from top to bottom and also comprises a pull rod, a drying agent is placed in a space encircled by the top cover, the transparent cover cylinder and the bottom plate, the isolation plate is arranged on a pull rod, and a ventilation hole is formed in the bottom plate. The oil immersed transformer breather with the isolation plate has the advantages that the isolation plate is arranged on the pull rod, the ventilation hole is formed in the bottom plate, so that the distance of air, which flows through the breaker, flowing through the drying agent is relatively large, the drying agent in the breather can be fully utilized, moreover, moisture in the air can be fully absorbed, and the filtering effect is better; and by rotating the pull rod, the drying agent near to the air outlet can also be pushed to the air inlet, and the utilization ratio of the drying agent is further improved.
Description
technical field [0001] The invention relates to an oil-immersed transformer respirator, more precisely an oil-immersed transformer respirator with a cutoff plate. Background technique [0002] In oil-immersed transformers, in order to prevent the impurities and moisture in the air from entering the transformer oil and affecting the insulation of the transformer oil, a respirator is required to filter the impurities in the air and absorb the moisture in the air. In order to facilitate installation, both the air inlet pipe and the air outlet pipe are usually arranged on the upper end of the respirator, but this structure cannot make full use of the desiccant in the respirator, usually the upper desiccant has expired and the lower desiccant has not been fully absorbed Moisture, and the desiccant must be replaced all at once, which is a serious waste; and it cannot completely absorb the moisture in the air flowing through the respirator.
