AI Technical Summary

Technical Problem

The existing voltage measurement device for high-voltage direct current transmission valve components lacks a protective structure, which makes it impossible to isolate the voltage measurement failure in time, easily causing damage to the device and resulting in poor safety.

Method used

A device was designed that includes components such as a base, voltage measuring device, protective box, lifting rod, fire extinguisher, and magnetic sheet. The device achieves rapid isolation and fire extinguishing protection in case of failure by using a motor to drive the measuring platform to flip, extinguish fire, attract magnetic sheet, and connect telescopic column.

Benefits of technology

The safety of the measuring device has been improved. Through rapid isolation and fire extinguishing measures, the measuring device has been protected, ensuring the stability and safety of the measurement.

Abstract

The invention discloses a high-voltage direct-current power transmission valve assembly voltage measuring device, which comprises a base and a voltage measurer, the two sides of the base are fixedly connected with mounting racks, the mounting racks are fixedly connected with the voltage measurer, the top of each mounting rack is provided with a connecting assembly capable of moving up and down, the top of the base is provided with a plurality of lifting rods, and the lifting rods are fixedly connected with the mounting racks. The tops of the multiple lifting rods are fixedly connected with the same protection box. By starting a motor, a second gear rotates to drive a first gear to rotate, so that a connecting shaft rotates, a measuring table is driven to turn over, an air cylinder and a clamping plate are loosened, a high-voltage direct-current power transmission valve assembly with a fault can be put into a protection box, and when the protection box moves downwards, an injection opening of a fire extinguishing tank punctures a film piece, so that the fire extinguishing effect is improved. And a fire extinguishing medium in the fire extinguishing tank can be sprayed into the protection box, so that fire extinguishing is carried out on the high-voltage direct-current power transmission valve assembly which breaks down, and the safety of the device during measurement is improved.
