Problems solved by technology
[0003] In the actual operation of the distribution network, due to the damage of the main components of the high-voltage drop insurance, the phase loss or outage of the distribution transformer occurs from time to time, resulting in power outages for users. Usually, when the distribution network operation and maintenance personnel arrive at the scene, the process of installing a new high-voltage fuse is too much. The cumbersomeness leads to the failure to replace the high-voltage fuse in time, resulting in a delay in power transmission and causing great economic losses to users

Embodiment 1
[0027] refer to Figure 1~4 , which is the first embodiment of the present invention, this embodiment provides a kind of convenient installation type emergency repair high-voltage fuse and device, and the convenient installation type emergency repair high-voltage fuse includes a high-voltage fuse unit 100, including two non-overlapping operation Ring A101, the single-strand copper core wire A102 and the single-strand copper core wire B103 arranged on both sides of the operating ring A101 and connected thereto, and the fuse 104 connecting the two single-strand copper core wires B103, the operation Ring A101 is a copper ring. The operating ring A101 is a copper ring. The setting of the operating ring A101 is to facilitate fixing the fuse 104. When winding the single-strand copper core wire A102, it can ensure that the fuse 104 will not be broken due to force. The single-strand copper core wire B103 The setting is to reduce the usage of the fuse 104 and save cost.

The invention discloses a convenient installation type emergency repair high-voltage fuse, which comprises two non-overlapping operating rings A, a single-strand copper core wire A and a single-strand copper core arranged on both sides of the operating ring A and connected thereto wire B, and a fuse connecting the two single-strand copper core wires B. And a convenient installation type emergency repair high-voltage fuse device, which includes a support unit, a winding unit and a housing unit. The winding unit is arranged on the side of the support unit, and the housing unit is fixed on the support unit and fixes the winding unit. The two ends of the high-voltage fuse are provided with two operating rings A, which are connected to the operating ring A through a single-strand copper core wire A and a single-strand copper core wire B, and a high-voltage fuse is connected between the two single-strand copper core wires B; the new The installation of the high-voltage fuse is faster and more convenient.
Description
technical field [0001] The invention relates to the technical field of high-voltage fuse replacement, in particular to a conveniently installed emergency repair high-voltage fuse and a device. Background technique [0002] High-voltage drop-out fuse consists of three parts: insulating support, moving and static contacts, and fuse tube. The static contact is installed at both ends of the insulating support, and the fuse tube is composed of an inner arc suppression tube and an outer phenolic paper tube or epoxy glass fiber cloth tube. [0003] In the actual operation of the distribution network, due to the damage of the main components of the high-voltage drop insurance, the phase loss or outage of the distribution transformer occurs from time to time, resulting in power outages for users. Usually, when the distribution network operation and maintenance personnel arrive at the scene, the process of installing a new high-voltage fuse is too much. The cumbersomeness leads to th...
