Description

Hanging type sealing stopper for drop-out fuse

Technical Field

The application relates to the field of drop-out fuses, in particular to a device which can effectively control the illegal private connection of a drop-out fuse by a power supply party.

Background

As shown in fig. 1, a conventional drop-out fuse generally includes an insulator 1 disposed vertically, an inlet terminal 2 and an outlet terminal 3 at upper and lower ends of the insulator 1, and a fuse tube 6 for connecting the inlet terminal 2 and the outlet terminal 3. Wherein, the wire inlet end 2 is provided with a clamping part 4 for clamping the upper end of the fuse tube 6; and the wire outlet 3 is provided with a trunnion box 5 which can carry the lower end of the fuse tube 6 and is provided for the fuse tube 6 to be opened laterally. When the power failure operation needs to be carried out on the power utilization party, the power supply party pulls the upper end of the fuse tube 6 by using the insulating rod, so that the fuse tube 6 is separated from the clamping part 4, the fuse tube 6 starts to rotate outwards and is opened sideways under the action of the trunnion box 5, and the fuse tube 6 can be taken down and removed by pulling the fuse tube 6 through the insulating rod at the moment, so that the power failure operation on the power utilization party is completed.

However, the fuse tube 6 is available everywhere in the prior art, and the power consumption can be recovered by only buying the fuse tube 6 with the corresponding model by the power consumption party and then resetting the fuse tube 6. This act of privately recovering electricity by the consumer can lead to the following adverse consequences:

1. the power utilization party cannot be effectively supervised, and the legal rights and interests of the power supply party cannot be effectively maintained, so that the capital loss of the power supply party is caused;

2. most of the power utilization parties are non-professional persons, and the drop-out fuse is always in a high-voltage environment, so that the personal safety of the power utilization parties is not guaranteed;

3. since the electricity consumer is a non-professional, the act of privately re-energizing can lead to the safety of the relevant line, further leading to unpredictable consequences.

At present, the present inventors provide a stopper for solving the technical problem that the behavior of a drop-out fuse for carrying out illegal private re-electricity on a power consumer does not generate an effective way.
