The normally opened contact of relay K4 is closed, and the instruction that controller 72 then sends out disconnection by-pass switch 3 keeps the main contacts of by-pass switch 3 disconnected
It opens, the normal step 1.1 that executes arrives step 1.5 if not detecting that the normally opened contact of electric leakage signal relay K4 is closed.
It is manual detection creepage protection function above, needs detect every month one time due to earth leakage protective device 12, for
Busy maintenance personnel is a kind of work load, therefore the function of detecting automatically of the utility model exploitation.Below to automatic week
Phase property detection control method is described.
It is internally provided with time timer unit in controller 72, is started automatically after the time cycle for detecting one month
Earth leakage detection functions, automatic earth leakage detection functions include the following steps：
Step 2.1, by-pass switch 3 is connected, specifically, the coil windings band of the control bypass closing relay of controller 72 K1
The normally opened contact of electricity, bypass closing relay K1 is closed, and the main contacts of by-pass switch 3 is connected.
Step 2.2, whether the main contacts of the detection of controller 72 by-pass switch 3 is connected, and 2.3 are thened follow the steps if connected,
Malfunction indicator lamp is lighted if being not switched on.The method whether detection by-pass switch 3 is connected is the detection bypass electricity of controller 72
Whether current transformer L2 has electric current, if there is electric current then illustrates to have turned on, illustrates to be not switched on if no electric current.
Step 2.3, creepage protection function is tested, specifically, controller 72 connects the electromagnetic coil of test Electromagnetic push-button 51
63, adsorpting iron plate 62 is driven button axle 61 to move downward by the effect of electromagnetic attraction, button axle 61 and then triggering electric leakage guarantor
Protect the testing button of device 12.
Step 2.4, whether detection test Electromagnetic push-button 51 executes the instruction that controller 72 is sent out, specifically, controller 72
