  • Page 3: Ⅰ、Product Introduction

    Ⅰ、Product Introduction ZXJB Single Phase Relay protection Tester the updated generation product developed by our company. It adopts latest power source technology, which make this instrument reach International standard and domestic advance level in circuit design, component selection, panel layout and internal structure. It is with powerful functions, excellent materials, clear testing project data, simple operation and ideal for Power Industry relay protection department.

    2) Time relay: Measure start value, return value and action time, error less than 0.2ms 3) Intermediate relay: Measure start value, return value, holding value and action time of coil 4) 4) Reclosing relay: Charge test of capacitance, charge time, reclosing time and middle components test.

    operating value and return value. I means normally open contact off delay is closed, II means normally open contact off delay is open. III means normally closed contact off-delay is open. IV: normally closed contact off-delay is closed. T4 is power supply output value regulation knob 5) Contact: the wiring terminal of the tested relay contact Remark: There should be no external power source for the relay contact when test replay operating time.

    terminal to output 0～5A（0～20A、0～100A）AC current, X1 indicates current voltage, output type ACV light will be on 3. DC voltage（0～220V）output Turn T1 to DC250V, close the synchronous switch, turn T4, J3 terminal to output 0～220V DC current, X1 indicates present voltage, output type ACV light will be 4.
  • Page 7 indicates relay with contact opening as operation value Relay operation value, return value and return factor measurement: Regulate output power according to point 4, select T3 to ,push synchronous switch, rotate slowly T4 Knob to relay operation, when indicator light is from off to on state, the current X1 is displayed as operation value. Continue to regulate T4 to relay rated value, then turn T4 to relay return, when the indicator light turns off, the X1 value is return value.

Reclosing（ DH—3 reclosing as example） ： DH—3type reclosing reply operation as below Connect wire by graph3, connect 3, 4 with J5 black column ( negative), connect 17 with J5 red column (positive) Note: when use ZJ3 contact to stop millisecond contact, remember to cut off the connection between ZJ3 to 1 to separate ZJ3 contact.
  • Page 9 See graph(a), the measurement of operation value, return value, operation time and return time is same as overrange, underrange relay Graph(b）to current hold relay. Firstly turn T2 to relay rated voltage value, switch on power, push set button, to make relay voltage coil joined into rated voltage value.
  • Page 10 Cut off the link between 10 and 11 terminal. Operate exactly like that for current relay to test operation current and return current, then step up AC current to the tested operation current value, record the present voltage, universal meter can be used to test the voltage between the two ends of J1 No brake Starting ampere-turns test...

  • Page 11: Ⅵ、Matters Need Attention

    Connect like above graph. Cut off the link between (4) and (6), the action loop take 39 turns, the brake circuit takes 14 turns, the regulator (minimum capacity 5KVA) and the instrument uses the same 220V power supply, adjust the brake Current to the required ampere turns, according to the AC relay to make the action current.

    seats, if damaged, replace the same type can get back to normal. Other non-fuse issues do not repair yourselves but contact with us 5. The output power cannot be short-circuited, the contact terminal cannot be short-circuited with the output power, so as not to damage the instrument. 6.
