The circuit breaker is one of the most important devices on which reliable operation of not only the switchgear on which they are installed, but often the entire power system, depends. The most important operation for circuit breakers can be considered the switching off of large short-circuit currents, reaching several tens of kA.
High-voltage circuit breakers of the traction substations of railways are prone to aging and wear during their service. Therefore, in order to balance this effect, different types of maintenance and repair are carried out during their service life. In addition, the life of the circuit breakers equipment is difficult to determine in advance as it depends on many factors, such as manufacturing technology, electrical voltage, environmental conditions and mechanical loads, temperature regimes, etc.
In order to increase the operational efficiency of SF6 circuit breakers, it is proposed to introduce one of the modern monitoring systems for SF6 circuit breakers "SMEV". Monitoring of circuit breakers is used to solve two main tasks. The first is control of the normal operation mode, it allows more efficient use of the circuit breakers resource and prevents its emergency conditions by timely withdrawal for repair. The second is the collection of information on the position of the switch for the control and automation systems of the electric power facility. The system for monitoring the parameters of the SF6 circuit breakers is designed to control the state of high-voltage equipment in order to determine the current parameters and predictive calculation of the main technological quantities. This system allows real-time scheduling of maintenance and repair of equipment in a more reliable and cost-effective way.
With the introduction of the system, the quality and efficiency of servicing the insulated electric circuit breakers of the railway supply system will increase, which will lead to more reliable electricity supply to consumers. Realization of the functions of forecasting will allow the timely warning of the failure of the circuit breaker. Detailed analysis of each switch-off of the short-circuit current circuit, obtaining reliable data on the switch-time and the value of the short-circuit current, will allow in automatic mode to calculate the switching resource of the circuit breaker. Comparison analysis with the previous disconnections will allow to follow the dynamics of the speed of switching the circuit breaker parameters during switching operations and determine the need for repair work to ensure full utilization of the circuit breakers resource.References
