The invention relates to a leakage protection device, in particular to an intelligent leakage protection device. The intelligent leakage protection device comprises an intelligent module unit, a relay, a mutual inductor, an operating mechanism and the like. The intelligent module unit is connected with the secondary parts of elements such as the relay and the mutual inductor, faults are judged by collecting voltage and current signals, and the operating mechanism serves as the switch breaking part. The intelligent leakage protection device has the phase splitting detection function and the intelligent breaker function, and the rated current and the short circuit breaking time can be adjusted in a multi-gear mode. The intelligent leakage protection device has the automatic reclosing function and the locking function. A protector is automatically switched on in terms of protector actions caused by impermanent faults, and the protector is switched off in terms of protector actions caused by repeated faults or permanent faults. In addition, the intelligent leakage protection device is attractive and compact in structure and convenient to install and use.
Description
technical field [0001] The invention relates to a leakage protection device, in particular to an intelligent leakage protection device. Background technique [0002] Leakage protection device is a grounding protection device used to prevent personal electric shock and accidents caused by electric leakage. When the leakage current of the circuit or electrical equipment is greater than the setting value of the device, or when people or animals are in danger of electric shock, it can act quickly to cut off the accident. The power supply avoids the expansion of accidents and ensures the safety of people and equipment. Therefore, the correct selection and maintenance management of leakage protection switches are the main technical and management measures for safe use of electricity. [0003] The current leakage protectors on the market are simple leakage circuit breakers or molded case switches, which cannot be called intelligent leakage protection. They have single functions, n...
