Problems solved by technology

Most of the domestic conventional high-altitude wiring pliers for transformers are wired in a push-pull manner. Due to the large number of parts, the push-pull locking device has a particularly complicated structure and small locking force, which is prone to loosening and jamming after locking the wiring.
At the same time, there are many parts in the return mechanism, and the structure is particularly complicated.
The contact force between the jaws is small, the current carrying capacity is small, and the contact resistance is large, which affects the test results of the test instrument

Abstract

The invention relates to a high-altitude wiring device for mutual inductor detection equipment, and belongs to the technical field of power equipment. The device comprises an operating connecting rod and a wiring clamp disposed at the top of the operating connecting rod. The wiring clamp comprises a movable jaw and a fixed jaw, which are vertically arranged in an opposite manner. A side surface of the movable jaw is provided with a threaded hole, and a screw rod passes through the threaded hole. One end of the screw rod is fixed on an insulating support through a bearing. The insulating support is fixedly connected with the operating connecting rod. The fixed jaw is connected to an installation seat which is located on the insulating support and extends outwards. One end of the screw rod is connected to a motor output shaft fixed on the insulating support. The movable jaw and the fixed jaw are provided with wiring ends. The device provided by the invention employs a stepping motor to drive the movable jaw to gradually clamp a high-altitude wire. The fixe jaw is installed through the spring, so as to protect the wire from being damaged. Afterwards, the movable and fixed jaws are used for taking and leading out electricity for testing.

Description

technical field [0001] The invention relates to a high-altitude wiring device for transformer detection equipment, which belongs to the technical field of electric power equipment. Background technique [0002] At present, in order not to disturb or interrupt the power supply, the principle of mutual inductance is mostly used for the test of the power line assumed to be at high altitude, which requires working at high altitude. Most of the domestic conventional high-altitude wiring pliers for transformers are wired in a push-pull manner. The push-pull locking device has many parts, a particularly complicated structure, and a small locking force, which is prone to loosening and jamming after locking the wiring. Simultaneously, there are many return mechanism components, and the structure is particularly complicated. The contact force between the jaws is small, the current carrying capacity is small, and the contact resistance is large, which affects the test results of the t...
