Overhead line plug-pull connection device

Abstract

The invention discloses an overhead line plug-pull connection device, which comprises an insulation shell, a wire clamp, a connection wire plug-pull connector and a clamping assembly, wherein the insulation shell is internally provided with a cavity; the lower end surface of the insulation shell is provided with a plugging hole for enabling the connection wire plug-pull connector to extend to the cavity; the wire clamp is fixedly connected onto the outer side wall of the insulation shell; the wire clamp and a power line are connected and fixed; the contact part of the wire clamp extends to the cavity of the insulation shell; the clamping assembly is fixed in the cavity of the insulation shell; the clamping assembly comprises at least one clamping part matched with the connection wire plug-pull connector; and the clamping part is connected with the contact part of the wire clamp. The overhead line plug-pull connection device has the beneficial effects that the distribution network rush repair time is reduced, the nearby device arranged in the surrounding line can be selected, a plug-and-pull connection device (a wire plug-pull connector and a grounding plug-pull connector) can be exchanged, field safety measures can be quickly completed, and the device is safe and efficient.

Description

technical field [0001] The invention relates to a plug-in connection device for overhead lines. Background technique [0002] When new high-voltage electrical equipment is connected to the overhead lines of the distribution network, live workers need to perform lapping operations on the drain wires at close range, which poses a high safety risk and can easily cause injury to the operators. [0003] During the maintenance and repair of the overhead line of the distribution network, in order to prevent personal electric shock accidents caused by electrostatic induction near the charged body or sudden reverse power transmission, it is necessary to install and ground all high-voltage equipment that may reverse power transmission in the overhauled overhead line section. It is time-consuming and labor-intensive, and the traditional grounding operation should be carried out in the power-off line. If the live line is directly grounded by mistake, it will lead to single-phase groundi...

[0003] During the maintenance and repair of the overhead line of the distribution network, in order to prevent personal electric shock accidents caused by electrostatic induction near the charged body or sudden reverse power transmission, it is necessary to install and ground all high-voltage equipment that may reverse power transmission in the overhauled overhead line section. It is time-consuming and labor-intensive, and the traditional grounding operation should be carried out in the power-off line. If the live line is directly grounded by mistake, it will lead to single-phase grounding of the line in the slightest, and will cause casualties to the operator in the severe case.
