AI Technical Summary

Technical Problem

The existing high-voltage test wiring clamps for substation equipment adopt a traditional clamp-shaped structure design, which requires operators to repeatedly open and close the wiring clamps multiple times, resulting in low wiring efficiency and a poor user experience.

Method used

A high-voltage test wiring clamp for power equipment was designed. It adopts a combination structure of main body, fixed clamp head, movable inner rod, moving clamp head, spring, clamp handle and transmission linkage. Through the cooperation of transmission linkage and spring, the cable end can be quickly connected and disconnected, and the lever arm is increased to reduce physical strength consumption.

Benefits of technology

It enables rapid wiring operations, improves wiring efficiency, reduces the physical exertion of workers, and is easy to carry and store.

Abstract

The utility model provides a high-voltage test wiring clamp for power transformation equipment, which relates to the technical field of electrical equipment and comprises a main body, a fixed clamp head, a movable inner rod, a movable clamp head, a spring, a clamp handle and a transmission connecting rod. A fixed tong head is welded to the end of the body, a movable inner rod is connected into the body, and a movable tong head is welded to the end of the movable inner rod. A spring is installed inside the main body, two forceps handles are connected outside the main body, transmission connecting rods are connected outside the forceps handles, and the transmission connecting rods are connected with the movable inner rod. When the metal wiring sleeve is located between the fixed clamp head and the movable clamp head, the ends of two cables needing to be connected are inserted into the two ends of the metal wiring sleeve, the two clamp handles are rotated inwards, the clamp handles drive the movable inner rod to move outwards through the transmission connecting rod, and the distance between the fixed clamp head and the movable clamp head is reduced. Pressure is applied to the metal wiring sleeve through the fixed clamp head and the movable clamp head, the metal wiring sleeve is pressed flat, the metal wiring sleeve makes close contact with the end of a cable, and rapid wiring operation is achieved.
