On-line monitoring system aiming at high-voltage circuit breaker

Abstract

The invention discloses an intelligent on-line monitoring system aiming at a high-voltage circuit breaker. The intelligent on-line monitoring system comprises an on-line monitoring device consisting of an on-line monitoring module group, a power module and an upper computer interface module, and an upper computer device connected with the on-line monitoring device, wherein the on-line monitoring module group comprises a circuit breaker separating brake loop disconnection monitoring module, a circuit breaker arc extinguish chamber vacuum degree monitoring module, a circuit breaker contact temperature rise monitoring module, a circuit breaker over travel monitoring module and a circuit breaker separating/connecting brake speed monitoring module. The five sub monitoring modules are connected with the upper computer interface module to realize data interaction between the five sub monitoring modules and the upper computer device, and the upper computer device performs monitoring data search and parameter configuration on the five sub monitoring modules by the upper computer interface module. According to the system, the measurement of each piece of state information is mutually separated from a power source power supply module, the internal mechanism of the circuit breaker is analyzed again, and the current running state parameter and state of the high-voltage circuit breaker are obtained accurately and efficiently.

Description

Technical field: [0001] The invention relates to online real-time overhaul and maintenance of power equipment, in particular to an intelligent online monitoring system for high-voltage circuit breakers. Background technique: [0002] As we all know, the maintenance method of power equipment is to carry out corrective maintenance after the occurrence of a fault, which is called accident maintenance, and then develops into a preventive regular maintenance at a fixed time interval. With the advancement of my country's power system reform, the development of the power market requires a more scientific maintenance mode—conditional maintenance, which evaluates and diagnoses the equipment in operation through various means, and gives targeted maintenance suggestions. The advantage of the condition-based maintenance mechanism is that it can prevent the occurrence of malignant accidents, avoid unnecessary damage to the organization caused by over-maintenance, or omissions caused by insuff...

AI Technical Summary

Problems solved by technology

[0005] However, for the equipment for online monitoring of high-voltage circuit breakers in power systems, there is currently no standard product for online monitoring in China, and most of the high-voltage circuit breakers with online monitoring functions can support relatively low functions. Single, cannot fully reflect the complete working status of the high-voltage circuit breaker
