Problems solved by technology

[0002] The protection function of the leakage protector is based on the premise that the power supply is normal, and the ground wire is abnormally charged or the load leaks to provide the protection function of cutting off the load power supply circuit. Because users generally use the socket switch to cut off the power supply of the leakage protector. The machine stops working to achieve the purpose of energy saving. Because of this, if the leakage protector loses its working power, if the ground wire is abnormally charged at this time, the leakage protector will not trip and cause an electric shock.
And so on, the poor contact of the socket is also equivalent to turning off the power supply of the leakage protector, which seriously affects the hidden danger of personal safety.

Embodiment 2

[0098] The implementation process and method of this embodiment and Embodiment 1 are basically the same, the difference is:

[0099] The regulator tubes D8 and D9 in the first embodiment are replaced by triodes D8 and D9; the silicon controlled rectifiers Q7 and Q8 can be replaced by field effect transistors Q8 and Q9, and their peripheral circuits are appropriately modified. Circuit schematic diagram see figure 2 .

Embodiment 3

[0101] The implementation process and method of this embodiment and Embodiment 1 are basically the same, the difference is:

[0102] The diode D16 is connected in series with the sustaining coil L1, and an energy storage capacitor C25 is connected in parallel with the sustaining coil L1 to provide stable energy for the sustaining coil L1 and prevent the sustaining coil L1 from generating noise. Refer to the specific circuit schematic diagram image 3 .

Abstract

The invention discloses an intelligent wireless network type leakage protector. The leakage protector comprises a live wire, a zero wire, a ground wire, a wall wire, a release, a rectification and voltage-stabilized circuit, an amplification circuit, and a zero sequence mutual inductor and a ground wire mutual inductor both connected to the amplification circuit. The leakage protector also comprises an optical coupler U1, an optical coupler U2, an optical coupler U3 and a single-chip microcomputer IC1. The intelligent wireless network type leakage protector overcomes shortcomings and avoids safety potential risks of all leakage protectors in the prior art, integrates all functions, plays a comprehensive protection role, and is intelligent, safe and reliable. The leakage protector achieves an isolation effect between water and electricity as the electricity is cut off when water flows out, so that the usage safety potential risks are prevented. By employing the leakage protector, abnormity caused by electrification or wiring errors of the ground wire is prevented. Operation states of the leakage protector can be remotely controlled through infrared rays.

Description

technical field [0001] The invention relates to the technical field of electricity safety protection, in particular to an intelligent wireless network leakage protector. Background technique [0002] The protection function of the leakage protector is based on the premise that the power supply is normal, and the ground wire is abnormally charged or the load is leaking to provide the protection function of cutting off the load power supply circuit. Because users generally use the socket switch to cut off the power supply of the leakage protector. The purpose of energy saving has been achieved by stopping the machine. Because of this, if the leakage protector loses its working power, if the ground wire is abnormally charged at this time, the leakage protector will not trip and cause an electric shock. And so on, poor contact with the socket is also equivalent to turning off the power supply of the leakage protector, which seriously affects personal safety hazards. Contents o...
