Tap terminal protection seat convenient to disassemble and assemble

Abstract

A tapping terminal protection seat convenient to disassemble and assemble comprises a ceramic seat body, and the ceramic seat body is provided with a through hole. A flange is formed at the lower end of the ceramic seat body, at least two sealing rings are fixed at the bottom of the flange, and the sealing rings surround the through hole; guide rails are pre-arranged on the left side and the right side of the through hole; a first clamping block, a second clamping block and a screw rod are further included, and the two ends of the second clamping block are fixed to the left side and the right side of the through hole respectively; the two ends of the first clamping block are in sliding fit with the two guide rails correspondingly. One end of the screw rod is rotationally connected to the second clamping block, and the screw rod is in threaded fit with the first clamping block; the tapping terminal is clamped and fixed through the first clamping block and the second clamping block, so that the protection seat is easy to mount and dismount; by adopting the ceramic seat body and fixing the two sealing rings at the bottom of the flange, the creepage distance between the tapping terminal and other terminals is increased, and the insulation protection of the tapping terminal by the protection seat is realized.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a tap terminal protection seat that is easy to assemble and disassemble. Background technique [0002] Generally, commonly used transformers include dry-type transformers and oil-immersed transformers. Compared with oil-immersed transformers, dry-type transformers have the advantages of better fire resistance, no pollution, low loss, low noise and obvious energy-saving effects. However, Dry-type transformers have higher requirements on the operating environment, for example, the environment should not be too humid or have too much dust and so on. At present, the tap terminal and the outlet terminal of the dry-type transformer are respectively placed on both sides of the transformer coil, and both the tap terminal and the outlet terminal are exposed, so that in a humid environment, the surface of the epoxy resin shell of the transformer is easy to A slight discharge...
