Description

Technical Field

[0001] The present application specifically relates to the technical field of circuit breaker monitoring, and in particular to a circuit breaker monitoring, analysis and alarm system. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect the current under normal circuit conditions and close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of fuse switches and over-underheating relays. Moreover, it is generally not necessary to change parts after breaking the fault current. The number of circuit breaker actions and the number of motor operations are important technical parameters for judging the operating status of circuit breakers. However, at present, mechanical digital display data is required. Affected by mechanical performance and environment, the data display is often inaccurate, with low accuracy and reliability. In addition, during comprehensive inspections, it is necessary to manually open the mechanism box to copy the data, fill in the table for calculation, and judge the operating conditions of the equipment.

[0003] The Chinese patent with announcement number CN104090230A discloses a real-time analysis and early warning system for safe operation of circuit breakers, including a circuit breaker monitoring device, an on-site monitoring device, a communication network and a remote monitoring terminal, wherein the on-site monitoring device includes a processor, a memory, a touch screen, a communication module, a signal processing unit, a fault diagnosis module and an alarm module, and the signal processing unit includes an amplification circuit, a filtering circuit and an AD conversion circuit; the circuit breaker monitoring device includes a current acquisition terminal for measuring the primary current signal of the circuit breaker, a circuit breaker detection terminal for collecting the mechanical state of the circuit breaker, and a circuit breaker environment detection terminal for measuring the environmental state of the circuit breaker. However, the system in this application integrates an intelligent fault diagnosis expert system for high-voltage circuit breakers, and in some cases, manual intervention may be required for further fault analysis and judgment.

[0004] A Chinese patent with announcement number CN103744018A discloses an online monitoring system for high-voltage circuit breakers, including an online monitoring device composed of an online monitoring module group, a power module and a host computer interface module, and a host computer device connected to the online monitoring device. The online monitoring module group includes a circuit breaker opening circuit disconnection monitoring module, a circuit breaker arc extinguishing chamber vacuum monitoring module, a circuit breaker contact temperature rise monitoring module, a circuit breaker overtravel monitoring module and a circuit breaker opening / closing speed monitoring module. The above five sub-monitoring modules realize data interaction with the host computer device by connecting to the host computer interface module. The host computer device collects monitoring data and configures parameters for the above five sub-monitoring modules through the host computer interface module. However, as the data that needs to be processed continues to increase, the difficulty of system processing may increase, resulting in false alarms or system paralysis.

[0005] In summary, with the continuous development of power systems and the improvement of their intelligence level, the demand for automation and intelligence in substation operation and maintenance is growing.
