The invention provides an electric energy security intelligent detection and control device which solves the problems that an existing electric energy detection and control device is single in function and cannot achieve intelligent detection or control, and relates to the technical field of monitoring and control of an electric system. The device comprises a voltage detection circuit and a resonance elimination and arc extinction circuit. The voltage detection circuit is connected with the resonance elimination and arc extinction circuit in parallel and then is connected with a disconnecting switch in series; the voltage detection circuit comprises a breaker, a voltage transformer and a control device, and the breaker, the voltage transformer and the control device are sequentially connected in series; the resonance elimination and arc extinction circuit comprises a breaker, a touch switch and a state detection protector, and the breaker, the touch switch and the state detection protector are sequentially connected in series; the disconnecting switch, the breakers, the touch switch, the control device and the state detection protector are respectively connected with a microcomputer controller. The intelligent detection and control device is reasonable in design and complete in function; the intelligent detection and control device can be provided for the electric system, and management of an automatic system can be facilitated. Real-time detection and automatic control are achieved through the microcomputer controller, overvoltage, resonance vibration and arc light grounding phenomena in the system can be eliminated, and real-time monitoring and feedback regulation can be achieved.
Description
Technical field: [0001] The invention relates to the technical field of power system monitoring and regulation, in particular to an intelligent measurement and control device for electric energy security. Background technique: [0002] In view of the fact that there are some unstable factors in the power circuit, the circuit designed to prevent such unstable factors from affecting the circuit effect is called a protection circuit. For example, there are over-current protection, over-voltage protection, over-heat protection, no-load protection, short-circuit protection, etc. The electric energy measurement and control device in the prior art and the detection device in the electric power equipment have relatively single functions, cannot realize intelligent detection and control, and are not convenient for automatic system management. Invention content: [0003] The purpose of the present invention is to provide an electric energy security intelligent measurement and contr...
