Metering-type intelligent circuit breaker based on internet of things

Abstract

The invention discloses a metering-type intelligent circuit breaker based on internet of things. The circuit breaker comprises a CPU (Central Processing Unit) module, a signal acquisition module, a metering module, a power module, a mechanical control module, a communication module and an input/output module, wherein the metering module comprises a metering chip; the power source module comprisesa self-generated power loop unit; the communication module comprises a wired 485 communication unit and a wireless internet of things communication module; the mechanical control module comprises a control signal output unit and an equipment signal feedback input unit; and the input/output module comprises a key unit and a display unit. The voltage signal in the circuit is converted by the power module into a signal that can be collected by the metering chip, and the signal is sent to the metering module; not only the requirements such as high precision metering, rapid protection action and reliable fault detection are implemented, but also the direct docking of data and the remote terminal is implemented, thereby greatly increasing the remote-controlled spatial distance, and improving thestatistical and deployment speed of the grid data.
