A circuit breaker power distribution status monitoring device

Abstract

The invention discloses a breaker power distribution state monitoring device. The breaker power distribution state monitoring device comprises a posture sensor module, a central processor, a 485 communication circuit, a GSM communication circuit, a two-key switch circuit, a power-switching circuit, a signal acquisition and conditioning circuit, a corresponding interface, an open-close type current transformer and a voltage transformer. The device monitors a breaker incoming line terminal voltage through the voltage transformer, the current transformer monitors a breaker outgoing line terminal current, the posture sensor monitors a breaker manual switch space state, and a breaker power distribution state can be monitored really. Logic processing and a logic judgment are performed on read sensor data through the central processor, and, when a large change of the breaker power distribution state occurs, power distribution state change information can be sent to a user in a 485 or GSM short-message manner. The device can monitor the power distribution breaker current, the power distribution breaker voltage, power distribution breaker open and closed states and a power distribution breaker fault state in real time, and can perform local and remote communication with the user; and the device has the advantages of comprehensive monitoring, flexible installation and usage convenience.

Description

technical field [0001] The invention belongs to the field of electric power automation, in particular to a power distribution state monitoring device using a circuit breaker with a manual switch for power distribution. Background technique [0002] Electric energy has become an essential energy source in our life. Power distribution is an extremely important link in the generation, transmission and use of electricity. As an important device in the power distribution system, the circuit breaker plays the role of distributing electric energy (starting and stopping the motor infrequently) and protecting lines and equipment (automatically cut off the circuit in case of overload or short circuit). [0003] The equipment distribution voltage, current and circuit breaker opening are related to the safe operation and economic benefits of the equipment. If the power distribution status of equipment can be monitored in real time, it will facilitate troubleshooting and minimize losse...
