An easy-to-test insulator and a high-voltage switch using the insulator

Abstract

The invention relates to the field of high-voltage electrical equipment, in particular to an easy-to-test insulator and a high-voltage switch using the insulator. The insulator includes a middle insert, a casting and an outer flange. There are sealing ring grooves on the upper and lower sides of the casting, and the upper and lower sides of the outer flange are respectively provided with the corresponding high-voltage switch cylinder. The sealing part of the sealing fit, the detection channel has a communication port located on the upper and lower sides of the outer flange and a detection port connected to the communication port, the communication port is located between the sealing part and the sealing ring groove, and the detection port is used for Cooperate with the corresponding leak detection equipment and be sealed; the damage of the sealing ring at any position can be detected from the detection port. Since the leak detection equipment performs one-to-one detection on the detection ports, the reliability of the test results is also guaranteed. The easy-to-test insulator of the invention solves the problems of time-consuming and labor-intensive leak detection and unguaranteed sealing performance of the current insulators during use.

Description

technical field [0001] The invention relates to the field of high-voltage electrical equipment, in particular to an easy-to-test insulator and a high-voltage switch using the insulator. Background technique [0002] Insulators (divided into pot type, disc type, etc.) are one of the most common parts in high-voltage equipment. They are often assembled between two high-voltage switch cylinders when in use, and they need to be strictly guaranteed to be in contact with the high-voltage switch cylinder. The sealing performance of the fit. At present, the seal fit between the insulator and the high-voltage switch cylinder is realized by the seal ring. The specific realization method should be explained in conjunction with the structure of the insulator. The outer flange of the ring and the trumpet-shaped casting connected between the intermediate insert and the outer flange. The outer edge of the casting has an outward edge, and the outer flange surrounds and is fixed on the outer...
