Embodiment Construction

[0009] Now further describe the technical solution of the present invention in conjunction with the accompanying drawings and embodiments.

[0010] like figure 1 The remote control dropout fuse shown includes a mechanical part and an electrical control part. The mechanical part includes a high-voltage porcelain bottle 6, a fuse tube 7, a push-pull rod 9, and a swing arm 8. The fuse tube 7 is installed on the swing arm 8, and one end is connected to the high-voltage porcelain bottle 6 through a movable shackle of the fuse, and connected to the lower high-voltage terminal 10. Electrically connected, the other end is fixedly connected to the moving contact, and the moving contact is connected to the upper high-voltage terminal 4 through the static contact that cooperates with it. The push-pull rod 9 is made of insulating material, and is connected with the swing arm 8 through a transmission mechanism. An arc extinguishing cover 12 is arranged on the outer periphery of the stati...

Abstract

The related remote control drop-off fuse comprises a mechanical part with a high-pressure porcelain bottle, a fuse pipe with a photo-adaptor on side, a push-pull bar, and a swinging arm; and an electric control part comprised mainly the actuator and the control circuit with a remote signal receiving processor and a controller. Thereby, the operation staff can remote control the fuse and feedback the field image on local computer by the photo-adaptor to realize the intelligent control with high efficiency.

Description

technical field [0001] The invention relates to a high-voltage drop-out fuse on a power grid, in particular to an automatic control drop-out fuse. The invention is suitable for the protection switch on the high voltage side of the power transformer. Background technique [0002] A high-voltage drop-out fuse is installed between the high-voltage line of the power grid and the transformer, which is convenient for the maintenance and repair of transformer equipment and lines or the needs of power limitation. Ordinary high-voltage drop-out fuses are generally connected by high-voltage porcelain bottles, fuse tubes, and high-voltage switches. When using a special high-voltage insulating rod, it is necessary to manually push it up or down. The operator needs to wear insulating boots and gloves during work. security incident. For this reason, Chinese Patent Publication No. is CN2456308 wireless remote control and manual dual-use drop-out fuse, a drive mechanism is set on the mov...
