Embodiment Construction

[0017] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] The high-voltage insulated contact includes a working part, the working part includes an extension section and a working end connected to the extension section, and the extension section is composed of a plurality of telescopic tubes with decreasing diameters nested in each other, the telescopic tube and the working part Both ends are made of metal material. The extension section is composed of multiple telescopic tubes, which expands the working range of the working end in the lateral direction, increases the operating distance from the high-voltage electrified body, and reduces the possibility of electric shock.

[0019] The high-voltage insulated contact also includes an insulating part, and the insulating part may be composed of a working part connecting piece connected with the working part and a sleeve rotatably connect...

Abstract

A high-voltage insulation contact comprises a working portion which comprises an extending portion and a working end connected to the extending portion, the extending portion is composed of multiple telescopic barrels in a nested mode, the diameters of the telescopic barrels are gradually reduced, and the telescopic barrels and the working end are made of metal. According to the high-voltage insulation contact, the extending section of the working portion can stretch out and draw back freely, working length is increased, an operator can remotely operate the high-voltage insulation contact, and the possibility of electric shock is reduced. The working portion and an insulation portion can relatively rotate freely by certain angles, and the high-voltage insulation contact is convenient to use, simple in structure and especially suitable for hot-line work at natural hazard places or accident sites.

Description

technical field [0001] The invention belongs to the field of electric power and relates to a high-voltage insulating contact. Background technique [0002] In the early stage of power grid construction, various tests are required to verify the safety of equipment and systems for new equipment and systems. High-voltage insulation rods are a common test tool for power equipment, mainly for operators to test live high-voltage wires and cables. Long-distance operation without direct contact, such as pulling or dragging high-voltage wires, turning on or off the drop safety switch, and knife switch. Insulating rods are mainly used for installation and removal of temporary grounding wires and live measurement and testing. [0003] High-voltage insulating rods or insulating rods are generally composed of a working part, an insulating part and a handshake part. The working part is generally made of metal or insulating material with high mechanical strength. The insulating part and ...
