Problems solved by technology

[0003] At present, there are many deficiencies in the power isolating switch blades. The existing power isolating knife switch equipment is rarely connected with a horizontal transmission rod. When working, the transmission ratio is small, the workload is heavy, and it is difficult to use. Some isolation cards are closed a

Abstract

The invention discloses a high-voltage isolation switch, and the switch comprises a static contact; the static contact is arranged at one end of an upper conducting rod, and one end of the upper conducting rod is embedded into the static contact; the upper conducting rod is tightly connected with a corrugated pipe arranged at one end of the intermediate joint; a lower conducting rod is arranged atone end of the middle joint and is mounted in the wiring base; the rocker is embedded into the wiring base through a cylindrical pin; the bottom end of the wiring base is provided with a rubber pad,and one side of the rubber pad is provided with a first porcelain sleeve. A second porcelain bushing is arranged on one side of the first porcelain bushing, and one end of the second porcelain bushingis mounted in the rubber pad; one end of the first porcelain sleeve is provided with a grounding knife bar installed on the surface of the combined pedestal. The switch is connected through the horizontal transmission rod, wherein the transmission ratio is greater in the working process, and the working efficiency is high; each set of isolation switch is matched with one motor operating mechanism, so mutual influence is avoided; intelligent operation can be adopted in the overhauling, debugging and accident states, so the switch is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a high-voltage isolating switch. Background technique [0002] With the development of modern electric power industry, the protection of electric power safety is emphasized, especially for the cut-off of power switching power supply. Power switches have been operating in a large number of power grids since the early 1980s. Different in structure, its operation and maintenance have its own characteristics compared with other types of isolating switches. The poles are connected by horizontal transmission rods, and the electric motor is used for normal operation, and the operating handle can be used for manual operation during maintenance, debugging and accident status. The opening and closing of the grounding switch can only use the manual operation mechanism operate. The isolating switch is composed of static contact assembly, main switch blade assembly, rotating porc...
