Description

Low-voltage overhead bare wire quick power-taking device

technical field

The utility model relates to electric power equipment, in particular to a power-taking device for overhead cables.

Background technique

At present, most of the temporary low-voltage power-taking methods for agricultural production (such as farmland irrigation, etc.) are to peel the hooks from the heads of the wires to be connected, and hang them directly on the bare wires of the three-phase low-voltage overhead lines through long wooden/bamboo poles, commonly known as "hooks". Get power".

When taking electricity for farmland irrigation, farmers bend the external wires connected to the three-phase pumps into hooks one by one, use bamboo poles or wooden poles to pick up the wire hooks and hang them on the three phases of lines A, B, and C one by one. Because the operating rod is a bamboo/wooden rod that is old and new, of different colors, and of different lengths, its insulation performance cannot be fully guaranteed, and there is a certain potential safety hazard. In addition, the contact surface between the hook and the overhead bare wire is small, the gravity is light, and it is easy to dance on the wire due to external factors such as wind blowing. Poor contact can cause ignition or decoupling, resulting in lack of phase of the pump motor, overheating, burning, or accidental contact with other phase wires. Cause the protection power switch of this section of overhead branch line to trip. In addition, the decoupling and sliding wires are often hung on the surrounding trees and other foreign objects. Once people or animals touch the decoupling wires, serious electric shock accidents may occur. occurrence, there is an urgent need to develop a safe and efficient fast power-taking device.

detailed description

The low-voltage overhead bare wire quick power-taking device includes a power-taking unit and an operating unit. It realizes that people can safely and efficiently take and separate power temporarily from low-voltage overhead bare wires while standing on the ground. The reliable connection between the ground power line and the overhead bare wire is realized through the clip hook with fastening function, and the matching telescopic insulating rod 9 is used so that the operator can easily take power from the hook 8 and separate it on the ground without having to climb the rod.
