Intelligent high-pressure vacuum circuit breaker

Abstract

The invention discloses an intelligent high-pressure vacuum circuit breaker, which is provided with an intelligent observing and controlling device. The intelligent observing and controlling device is provided with an intelligent core device as a microprocessor; an operating mechanism and a vacuum circuit breaker body are of an integral structure; the operating mechanism and a vacuum arc extinguish chamber are arranged in front and back; and the vacuum arc extinguish chamber is longitudinally arranged in a tubular insulating cylinder. Through the technical scheme of the invention, dynamic monitoring on various parameters of current, voltage, operating positions, working environment, states and the like is realized, on-line state detection is carried out on a device, intelligent diagnosis, control and protection are carried out on the core control device, and analysis and process can be carried out on monitored data; maintenance is little or free; functions of automatic protection, automatic regulation, running state monitoring, intelligent operation, communication and the like are achieved; and a comprehensive solution is provided for the intelligentization of the high-pressure vacuum circuit breaker.

Description

technical field [0001] The invention belongs to the technical field of electric switchgear, and relates to the technology of high-voltage switchgear. More specifically, the invention relates to an intelligent high-voltage vacuum circuit breaker. Background technique [0002] In the field of 7.2kV ~ 40.5kV high-voltage switchgear, vacuum circuit breakers are widely used due to a series of advantages such as high reliability, small size, light weight, low noise, and the ability to achieve less maintenance and maintenance-free throughout the lifespan. In the power distribution system in various fields such as electric power industry, industrial and mining enterprises, railway transportation, etc., it is one of the main equipment that is indispensable for the production and operation of the electric power industry. Because the high-voltage field involves insulation, electric field and other issues, the vacuum circuit breaker is mainly used as the core actuator of the complete se...

Problems solved by technology

A single component is manufactured by different manufacturers, the matching of its system is often not optimal, and the coordination and reliability of the product is poor

Moreover, the volume of the equipment is large, the material consumption is large, the workload of manufacturing, commissioning and operation, and maintenance is large, and the technical requirements are high.

In addition, the internal parameters of the circuit breaker are difficult to obtain, and it is difficult to judge the remaining service life of the switchgear and calculate the maintenance period
