Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] 1. Integrated signal sensing method for mechanical condition monitoring of high-voltage circuit breakers

[0058] Accurate and effective signal sensing method is the basis of online monitoring and fault diagnosis technology. The operation process of the circuit breaker corresponds to a series of mechanism actions and collision processes, which can generate continuous vibration signals, which must contain rich information about the operation process; therefore, the mechanical performance and abnormality of the circuit breaker can be monitored by monitoring vibration events and their changes And get. In order to make the extraction of mechanical state features more diverse and more effective, multi-channel sensing signals that reflect the operating conditions of the equipment should be obtained at the same time - mechanical vibration signals, trav...

Abstract

The invention discloses an on-line monitoring and diagnosing system for the mechanical state of a high-voltage circuit breaker. The system comprises a multi-path sensor which is arranged on a high-voltage circuit breaker body and located in a switch operation mechanism box and can reflect the operation state of a device. The multi-path sensor is connected with a signal conditioning device through a circuit, and the signal conditioning device is connected with an on-line monitoring server through a circuit. The on-line monitoring server comprises a data acquisition module which is in communication with a network transmission module, a data storage module, a data analysis module and a report printing module. The data storage module is in communication with the report printing module, the data analysis module and a data retrieval module, and the data analysis module is connected with the data storage module and the report printing module. The invention further discloses a monitoring and analyzing method utilizing the system. Therefore, mechanical failures of the high-voltage circuit breaker can be effectively diagnosed and a superior failure classification function is achieved.

Description

technical field [0001] The invention relates to an on-line monitoring and diagnosis system and method for the mechanical state of a high-voltage circuit breaker. Background technique [0002] In recent years, with the prosperity and development of the economy, the demand for power system capacity and energy has increased, and higher and higher requirements have been put forward for the reliability and economy of the power system. As the link between power generation and power consumption, high-voltage circuit breaker's reliable operation is of great significance to ensure the safety of the power grid. The high-voltage circuit breaker plays two roles in the power system: one is the control function, that is, according to the operation requirements of the power grid, a part of the electrical equipment or line is put into or out of the running state, and turned into a standby or maintenance state; the other is the protection function, that is, When electrical equipment or line...
