Line principle explanation：
Press the power on switch S1 in main switch circuit 2, catalyst K1 closes, power supply indicator LAMP-1 is bright, treats
Survey product earth leakage protective device and obtain electric, press the reset switch on product to be measured, product to be measured obtain electric so that load display lamp
LAMP-2 is bright, represents that product to be measured is in closure state.
Press the test starting switch S3 in test power output circuit 4, catalyst K2 closes, transformator T1 former limit band
Electricity, secondary exports low-voltage, high-current, makes product to be measured produce remaining connection breaking current I Δ m by permutator S6, I Δ m's
Size depends on transformator T1 secondary output voltage U and loop resistance R, and I Δ m=U/R, by breaking capacity testing circuit 5
AmmeterThe remaining size connecting breaking current I Δ m of detection, and the oscillograph detection by being connected with outfan P1 and P2
The drop-away time of product to be measured.
Switch S2 is emergency stop push button, when finding any exception in test process, can press S2 at any time, make relay K1
Power-off, stops product to be measured and test circuit are powered, thus stopping testing.
Single-pole double-throw switch (SPDT) S5 is test/debugging function selecting switch, when S5 is transformed into test gear, time-delay relay
K3 plays defencive function, protects product to be measured and test circuit not because damaging by high current for a long time, time-delay relay K3
Delay time be set greater than the break of product to be measured, but no more than 1 second；On the other hand, when S5 is transformed into debugging shelves
During position, external adjustable resistance RX, by current transformer T2, galvanometerSample resistance R1 carrys out the output of test transformer T1
Whether capacity meets the specified remaining connection breaking current I Δ m that test request output current is not less than product to be measured.
When product to be measured can not be threaded off at the appointed time, whole test loop will pass through remaining connection for a long time and divide
Test/debugging function selecting switch S5, it is possible to damage equipment and product to be measured, need to be changed during proper testing by power-off stream I Δ m
To test gear, when pressing test starting switch S3, catalyst K2 closes, and test loop is started working, and time-delay relay K3 leaves
Beginning timing, when product to be measured can not be threaded off in maximum break, time-delay relay K3 can be dynamic after the setting time reaches
Make, make normally-closed contact K3-1 disjunction, catalyst K2 forces disjunction, stops powering to test loop.
Wherein, permutator S6 is the selecting switch that breaking capacity is connected in test L pole with N extremely residue respectively.
