Isolating switch

Abstract

The invention relates to an isolating switch. The isolating switch comprises an electric conduction mechanism, an insulating mechanism, an operating mechanism, a transmission mechanism, a base and a grounding switch. The electric conduction mechanism is connected with the insulating mechanism and the transmission mechanism. The insulating mechanism and the transmission mechanism are fixedly connected to the base. One end of the operating mechanism is fixedly connected to the base, and the other end of the operating mechanism is connected with the transmission mechanism. The isolating switch further comprises a counter, wherein the counter is connected with the transmission mechanism and used for counting the number of motions of the transmission mechanism. The counter is arranged in the isolating switch and can correctly reflect the number and the condition of the motions of the isolating switch, and therefore the running state of the isolating switch can be dynamically monitored, overhaul strategies can be reasonably and effectively generated and suitable for actual circumstances, and the technical problem of ensuring safe and reliable running of the isolating switch is solved.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to an isolating switch with a counting function. Background technique [0002] In recent years, great progress has been made in material technology and process quality of isolating switches. Many manufacturers have proposed the maintenance-free maintenance concept of isolating switch mechanical parts and contacts. This has reduced the maintenance workload to a certain extent, so the isolating switch has been transformed from the previous regular maintenance to the current status maintenance, which has continuously extended the maintenance period of the isolating switch. However, in offshore areas with high salt density or around highly corrosive industrial exhaust gas environments, corrosion, aging and other problems of isolating switches still exist, which directly affect the reliability and safety of power supply of the system. [0003] In the normal operating state of...

However, in offshore areas with high salt density or around highly corrosive industrial exhaust gas environments, corrosion, aging and other problems of isolating switches still exist, directly affecting the reliability and safety of power supply of the system

[0003] In the normal operating state of the isolating switch, there are the following problems: 1. If it is not operated for a long time, the mechanism will be jammed, the bearing will be rusted, and the forced operation will often lead to damage and deformation of the parts; , resulting in contact burns, deterioration of contact spring elasticity, wear and tear of transmission mechanism and operating mechanism

Through analysis, it can be found that isolating switches are different from equipment such as transformers and circuit breakers. Isolating switches do not directly reflect the characteristic quantities of their health status. Routine tests and diagnostic test items are limited to infrared temperature measurement, appearance inspection and operation inspection. and risk assessment stage lack of sufficient information and data to support
