Abstract

The invention provides an online monitoring device for a circuit breaker operating mechanism. The online monitoring device comprises a data acquisition module, a processing module and a communication module, wherein the output end of the data acquisition module is connected with the input end of the processing module; the communication module is connected with the processing module and comprises multiple uplink network interfaces; and the data acquisition module is used for acquiring a switching-closing signal of the circuit breaker and a contact travel signal of the circuit breaker. According to the online monitoring device for the circuit breaker operating mechanism, the cable number is greatly reduced, in addition to cables used by the power supply, the other control signals, status signals, monitoring information and the like can be transmitted to a switch cabinet or the background by virtue of digital signals (electric or optical communication signals), namely all the signals can be transmitted by virtue of a network cable. Meanwhile, the status signal contact number of auxiliary switches and the like and the aviation plug joint number are correspondingly reduced, secondary wiring is effectively simplified, and the switch cabinet production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of monitoring of circuit breaker operating mechanisms, in particular to an online monitoring device for circuit breaker operating mechanisms. Background technique [0002] With the development needs of smart grid construction, new requirements are put forward for substation equipment. The intelligent unit can be added to the original equipment to realize the intelligentization of the equipment; the integrated design of the intelligent unit and the switchgear can be achieved. To become an intelligent switchgear, the development trend of the current product is from the intelligent switchgear to the intelligent switchgear. [0003] The existing switchgear adopts comprehensive automatic protection, and its control signal is transmitted to the mechanism box through the cable and the aviation plug to realize the control of the circuit breaker mechanism, the opening and closing signal of the circuit breaker, the si...
