Abstract

The invention relates to a circuit breaker state monitoring device with multi-feature parameter fusion and a monitoring method thereof. The monitoring device includes a state information collecting module, a control system module, a state monitoring IO module, a state monitoring control module, a state monitoring human-computer interaction module, a GPRS processing unit, a WIFI module and a powermodule. The device is more reliable to judge the fault state of a circuit breaker compared with a single auxiliary contact, the timeliness of the transmission of a circuit breaker state and fault information is improved by using the GPRS processing unit, the information is transmitted by using wifi, and the simplicity of operation and maintenance is improved by a scheme of viewing the informationthrough a mobile phone browser.

Description

technical field [0001] The invention belongs to the technical field of power system distribution automation, and in particular relates to a circuit breaker state monitoring device and a monitoring method for multi-feature parameter fusion. Background technique [0002] The circuit breaker is an important device in the power system. It has the function of connecting and cutting off the normal load current and the short-circuit current in the event of an accident. If the circuit breaker fails, malfunctions or refuses to operate, it will affect the safe operation of the power grid and cause serious as a result of. In an unattended substation, it is necessary to monitor the opening and closing status of the circuit breaker in the substation. At present, the status monitoring of the circuit breaker is mainly fed back through the status auxiliary contact of the circuit breaker, because the status auxiliary contact is separated from the circuit breaker. It can be linked with the c...
