Power distribution network ground potential live line connection T wiring device

Abstract

The invention provides a power distribution network ground potential live line connection T wiring device, which comprises a wiring clamp body, a fixed clamping block, a movable clamping block, a fixed clamping plate, a movable clamping plate, a lifting assembly and an insulating worm and gear assembly. The fixed clamping block is arranged on the wiring clamp body and extends along the horizontaldirection together with the movable clamping block. The fixed clamping block and the movable clamping block are oppositely arranged and form a first wire clamping space. The fixed clamping plate is arranged on the wiring clamp body and extends along the vertical direction together with the movable clamping plate. The fixed clamping plate and the movable clamping plate are oppositely arranged and form a second wire clamping space. The first wire clamping space is located on one side of the wiring clamp body, and the second wire clamping space is located on the other side of the wiring clamp body. The lifting assembly is connected to the lower surface of the movable clamping block. The worm and gear assembly is used for driving the movable clamping block to ascend and descend. The T-shaped wiring clamp can realize live line connection in a live state, and can prevent power failure caused by live line connection from influencing normal power supply to users.

Description

technical field [0001] The invention relates to the technical field of electric power bonding, in particular to a T-connection device for ground potential live bonding of a power distribution network. Background technique [0002] In a high-voltage power system, when a new line or a new user transformer needs to be connected to the power network and put into operation, the live wire device generally used in the current power distribution line is a copper-aluminum parallel groove clamp, which is a kind of It is a device used in 35kV and 10kV distribution network line lapping and T-connection. At present, new 10kV new lines and new users need to be used for power outages and ditch line clips T-connection and fire-fighting, and power-off fire-bonding needs to be in accordance with the requirements of the power industry. Applying in advance, the application period is long, and power outages need to be planned as a whole, which greatly reduces the convenience for new users to use...

Applying in advance, the application period is long, and power outages need to be planned as a whole, which greatly reduces the convenience for new users to use electricity. At the same time, power outages will inevitably reduce the power supply reliability of the line, resulting in the loss of power supply and sales
