充电指示：Charging indicator III Impulse test 1. Test principle Fig 1 Circuit diagram for JS-type operating cycles counter (a) JS-type (b) JS-8 type R1, R2-nonlinear resistance C-Energy-storage capacitor L-Counter coil A silicon diode Figure 1 is circuit diagram of JS-type operating cycles counter. Figure 1 (a) shows circuit diagram of JS-type operating cycles counter, also called dual-valve plate structure. - Page 8 Figure 1 (b) shows circuit diagram of JS-8 type operating cycles counter, it is rectifier type structure. When the arrester operating, voltage drop on the valve R1 charge capacitor C through full-wave rectifier, then C discharge to L of electromagnetic counter and let it count. For this counter, the resistance value of valve R1 is small (when at 10kA, the voltage drop is 1.1kV), current capacity is larger (1200A square wave), the minimum action current is 100A (8 / 20μs) impact current.

with damp and damaged. "Regulation" provides that continuously test for 3 to 5 times, each action should be normal, each time interval should be not less than 30s. After test logger should be set to zero. 3.Operation method 1. Let the output terminal of instrument connect to the two ends of arrester counter (the connecting lead should be as short as possible), red terminal connect to upper end, black terminal connect to earth terminal. -

Under the shutdown state of the instrument, the wiring mode is the same as the impact test to form a circuit, after the wire is connected, press the current and voltage switch, and then can start! At this time, the instrument is in the state of electrical flow output.When checking, adjust the current to adjust the potentiometer, compare the instrument dial indication and the sample dial display, in order to determine whether the sample... - Page 11 1.
