Abstract

The invention belongs to the technical field of circuit protection and discloses a protection device and a method of a self-powered circuit. The protection device of the self-powered circuit is provided with a measuring circuit system. The measuring circuit system adopts a special line section. The current acquisition and analysis system uses intelligent digital ammeter to measure the current of the measurement circuit. The electric energy consumption acquisition and analysis system uses an electric energy meter to measure the electric energy consumed by the measurement circuit, and the temperature detection system uses a temperature sensor and a single chip microcomputer to measure the real-time temperature of the circuit, intelligently processes the collected data through an intelligentprocessing system and transmits the collected data to an alarm system, and displays the terminal. The invention measures each index of the measuring circuit and intelligently monitors and processes, and indirectly protects the self-powered circuit.

Description

technical field [0001] The invention belongs to the technical field of circuit protection, and in particular relates to a protection device and method for a self-powered circuit. Background technique [0002] Self-powered technology is a new type of power supply technology. It converts various energies in the surrounding environment into electrical energy to drive low-power electronic devices to operate. Using self-powered technology can effectively achieve zero power consumption. Traditional The self-powered circuit protection method adopts direct protection methods such as thermistors. When the circuit is operating normally, the protection resistor is still consuming part of the electric energy, resulting in a decrease in the utilization rate of the electric energy generated by the self-powered circuit. [0003] In summary, the problems in the prior art are: [0004] The traditional self-powered circuit protection method leads to a decrease in the utilization rate of elec...
