Earth leakage protective device connects, and another fixing end of rotating potentiometer is connected with earth terminal by ammeter, and rotating potentiometer leads to
Cross earth terminal connection the earth, the rotating shaft transmission connection of the motor output shaft and rotating potentiometer, the dc source power supply
To electric machine controller, the electric machine controller is connected with motor control, and electric machine controller possesses wireless communication function, the remote control
Device with motor controller controls by being wirelessly connected.
A kind of described portable secured earth leakage protective device on-line measuring device, it is characterised in that：The rotary current potential
Load resistance is also associated between device and power end.
A kind of described portable secured earth leakage protective device on-line measuring device, it is characterised in that：The remote control is more
Passage remote control, a remote control can control multiple electric machine controllers simultaneously.
A kind of described portable secured earth leakage protective device on-line measuring device, it is characterised in that：The motor is direct current
Motor, or stepper motor, when to be fuzzy control during direct current generator, when to be high-precision control during stepper motor.
After the utility model is connected with earth leakage protective device, the earth, the rotary current potential of operator's hand-held remote controller remote control
Device acts, so as to change resistance size, and by the change of ammeter kinetic current, without the hand-held inspection of operator after connecting the line
Survey, and connect that work is simple, can intuitively observe the change of electric current, there is the advantages of detection efficiency is high, security is good.
Brief description of the drawings
Fig. 1 is prior art detection principle diagram.
