Embodiment Construction

[0020] The mechanical failure of the circuit breaker will lead to changes in the relevant characteristic parameters of the circuit breaker's operating mechanism, transmission mechanism and arc extinguishing chamber. Therefore, an in-depth understanding and research on the state changes of the circuit breaker mechanism is of great significance for the mechanical status monitoring of the circuit breaker and its accessories.

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] At present, the state detection research on the mechanical characteristics of high-voltage switches has been reported in relevant literature at home and abroad, but there is no effective means for processing the collected mechanical state parameters of high-voltage switches in the prior art, and some processing models in the prior art The establishment of the system is too simple, and only a part of the state parameters are considere...

Abstract

The invention relates to the field of high-voltage equipment monitoring, in particular to an inversion method and device for mechanical faults of high-voltage switches. The present invention establishes a mechanical failure simulation system of a high-voltage switch, inputs the initial oil pressure and initial air pressure, and obtains the transmission system dynamics model through the simulation calculation of the operating mechanism simulation model, the transmission system dynamics model and the arc extinguishing chamber airflow field simulation model Output the theoretical stroke curve of the displacement with time, and compare it with the actual stroke curve to adjust the correlation coefficient in the simulation system, and finally get an accurate simulation system. The present invention establishes an accurate mechanical fault simulation system for high-voltage switches, which can monitor the mechanical state parameters of high-voltage switches in real time, transmit them to the background simulation center through the remote network for mechanical fault inversion, predict the development trend of faults, and realize real-time early warning and fast and accurate faults Overhaul and improve the intelligent level of high-voltage switches.

Description

technical field [0001] The invention relates to the field of high-voltage equipment monitoring, in particular to an inversion method and device for mechanical faults of high-voltage switches. Background technique [0002] The field operation experience of high-voltage switches shows that mechanical failure is one of its common frequent failures. Taking circuit breakers as an example, circuit breakers, as important high-voltage and high-current switching electrical equipment in power systems, play an important role in the system, and because It plays an important role in the system, and the circuit breaker is the key maintenance object. Power technology workers have been working on the mechanical status monitoring of the circuit breaker, and even early warning, reducing or cutting off various power outages caused by the unplanned outage of the circuit breaker. Possibly exempt or lessen the scope of impact on the overall system. [0003] The external conditions of the mechani...
