T-connection power line clamp installed in high-altitude live-line mode

Abstract

The invention discloses a T-connection power line clamp installed in high-altitude live-line mode. The T-connection power line clamp comprises a T-wiring clamp body, a clamp, a first insulating rod and a second insulating rod, wherein the T-wiring clamp body comprises a chuck, a cable pressing plate and a positioning bolt, one end of the positioning bolt penetrates out of a screw hole in the bottom of the chuck in a threaded mode and is connected with the cable pressing plate, the top of the first insulating rod is embedded into the bolt head of the positioning bolt, the chuck is provided witha binding post, the clamp comprises an upper clamping plate, a lower clamping plate, a connecting plate and a screw rod, the upper clamping plate is hinged to the top of the connecting plate, the lower clamping plate is fixed to the bottom of the connecting plate, one end of the screw rod penetrates out of the screw hole of the lower clamping plate and provided with a ball abutting against the bottom of the tail end of the upper clamping plate, and the other end of the screw rod is provided with a connecting head in threaded connection with the second insulating rod. According to the T-wiringpower line clamp, branch connection can be conducted on a line, mechanical fastening force is provided, current is conducted, a cable can be pre-positioned, the electrical conductivity and the connection reliability are enhanced, installation can be conducted without power failure, and the power supply reliability is effectively improved.

Description

technical field [0001] The invention relates to the technical field of power distribution overhead line connection, in particular to a T-connection power line clamp for high-altitude live installation. Background technique [0002] In the daily 10kV insulated overhead line live fire connection operation method, the traditional method can only adopt the method of power failure or borrow a live work vehicle for assistance, and the operator climbs up to perform manual operation, because there is a certain safety in this live work method Hidden dangers, and power outage operation will also affect the normal operation of power, which is not only inefficient but also unable to meet the increasing demand for safe power consumption. For example, the patent with publication number CN210167729U provides a kind of pre-twisted wire T-connection clamp, which performs T-connection through twisted wire, enhances the firmness of the connection, and increases the contact area between the wir...

Problems solved by technology

[0002] In the daily 10kV insulated overhead line live fire connection operation, the traditional method can only be assisted by power failure or borrowing a live work vehicle, and manual operation is performed by the operator climbing up, because there is a certain safety in this live work method Hidden dangers, and power outage operation will also affect the normal operation of power, which is not only inefficient but also unable to meet the increasing demand for safe power consumption

For example, the patent with the publication number CN210167729U provides a kind of pre-twisted wire T-connection clamp, which performs T-connection through twisted wires, enhances the firmness of the connection, and increases the contact area between the wire clamp and the wire, but this method requires power-off operation. And there is an unstable screw connection, and the work efficiency is low
