Intelligent protection device for safe power utilization

Abstract

The invention discloses an intelligent protection device for safe power utilization, and relates to the technical field of power equipment. The main points of the technical scheme of the invention arethat the device comprises a distribution box and an upper computer; the interior of the distribution box is provided with an intelligent protection device and a circuit breaker; the intelligent protection device is provided with a current sensing detection module and a single-chip microcomputer connected with the current sensing detection module; the current sensing detection module comprises a current sensor, a leakage current sensor and a short circuit detection device; the current sensing detection module is connected with a signal amplifier; the circuit breaker is connected with an automatic power recovery module; the automatic power recovery module comprises an intermediate relay, a time relay and a bridge-shaped rectification filter circuit. The device can monitor the working stateof the power supply circuit in real time and quickly and accurately analyze and judge the electric leakage, electric shock and short circuit faults, can control the circuit breaker to accurately act according to circuit faults for the reliable safety protection of the power supply circuit, and can control the power supply system to recover power supply after the faults are removed.

Description

technical field [0001] The invention relates to the technical field of electric equipment, and more specifically, it relates to an intelligent protection device for safe electricity use. Background technique [0002] Production and life are inseparable from electric energy. With the development of the national economy and the improvement of people's living standards, the technical requirements for electrical installation are getting higher and higher. Of course, the safety of electricity use cannot be ignored. At present, there are various protective measures, such as fuses. , Circuit breakers, and leakage protectors are protected between levels, but limited by the mechanical properties of the equipment, setting parameters, and service life, sometimes malfunctions occur or fail to operate reliably when a fault occurs. Therefore, the current intelligent level of electricity safety protection still has room for development and will become an inevitable trend. [0003] In the ...
