Abstract

The invention discloses a portable 35KV fuse core replacing device. A fuse porcelain bushing is fixed on a support insulator. Wiring end cover plates are arranged at the two ends of the fuse porcelain bushing to form a closed area in which a fuse tube is wrapped. The fuse tube and wiring terminals form circuit connection. The fuse porcelain bushing and the wiring end cover plates are connected by cover plate clamping devices. The left ends of the cover plate clamping devices are fixedly connected with the fuse porcelain bushing, and the right ends of the cover plate clamping devices are detachably connected with the wiring end cover plates through track clamping slots. The wiring end cover plates are provided with clamping parts corresponding to the track clamping slots. When the clamping parts are in the narrow areas of the track clamping slots, the wiring end cover plates are clamped; and when the clamping parts are in the wide areas of the track clamping slots, the wiring end cover plates are released. The corresponding core replacing method of the invention comprises the steps of unscrewing connectors, removing the wiring end cover plates, replacing the fuse tube, closing the wiring end cover plates, tightening the connectors, and the like. The device and the method of the invention have the characteristics of short core replacing time and simple operation.

Description

technical field [0001] The invention relates to the technical field of overload and short-circuit protection for electrical equipment such as high-voltage transmission lines, voltage transformers, and voltage transformers, and in particular to a portable 35KV fuse core replacement device. Background technique [0002] The 35kV high-voltage current-limiting fuse is suitable for AC 50HZ, rated voltage 35KV systems, mainly used in 35kV systems for rural and urban power grids, and can also be used in conjunction with other electrical appliances (such as switches, contactors, etc.) as motors, transformers, Overload or short circuit protection of electrical equipment such as capacitors; it can also be used in other similar places. [0003] At present, 35kV fuses are composed of melt tubes, porcelain sleeves, fastening flanges, rod-shaped post insulators and terminal caps. Fix the terminal caps and fuse tubes at both ends in the porcelain bushing by pressing, and then fix the porc...
