Problems solved by technology

Theoretically speaking, the patent mentions a method of "maintaining the balance of the flowing current through reversely connected coils", but this method is only a way to maintain the balance of the current flowing on the parallel load. In other words, the theory has absolutely nothing to do with the prevention of electric shock accidents caused by the current flowing from the exposed contact part to the earth

Abstract

The invention relates to the technical field of electricity utilization safety, in particular to a balancing device for reducing electricity leakage, which comprises a power supply, a balancing coil module, a preset load circuit and a leakage load circuit, and is characterized in that a first coil N1 can circulate supply current flowing from the power supply to the preset load circuit to generate a forward magnetic field; the second coil N2 can circulate a return current flowing from the preset load circuit to the power supply to generate a reverse magnetic field, and the third coil N3 can be provided with a current to generate a compensation magnetic field capable of compensating the difference between the forward magnetic field and the reverse magnetic field. Therefore, the magnetic field and the current in the balancing coil module are kept in a balanced state, the effects of reducing leakage current and maintaining basic power supply are achieved, and when electrical equipment is drowned or a human body is in an electric shock, the leakage (contact) current can be effectively reduced, and power supply to the electrical equipment is maintained, so that personnel safety is ensured, and basic operation of the electrical equipment is maintained.

Description

technical field [0001] The invention relates to the technical field of electricity safety, in particular to a balance device for reducing electric leakage. Background technique [0002] With the gradual popularization of various electrical appliances and electronic devices, people's demand for various electricity consumption is also increasing. In most (family or industrial) electricity consumption environments, mains power is a stable and convenient source of electricity. , and the current city power supply is transmitted by the power plant through high-voltage wires, and then transformed to various fixed voltages for different end consumers to connect to electrical appliances and electronic devices through wires according to their needs; however, in In the general living environment and the process of using electricity, many natural disasters or human negligence will often be encountered, resulting in various leakage (shock) situations. [0003] As we all know, when elect...
