TCW Test Transformer Power Control Console

Test transformer control box



Test transformer control box has the characteristics of convenient use and maintenance, superior performance, safe and reliable use, beautiful appearance structure, durable, and easy to move. It is essential equipment for power supply enterprises, large factories, metallurgy, power plants, railways, and other departments requiring power maintenance. It adopts advanced microelectronic processing technology, all usage processes can be set in advance, full Chinese interface, simple and clear operation. After all test items are set, the test is automatically performed without manual intervention.



Operation box (console) usage method:　





(1) Check whether the main power supply matches the input power * (220V for below 10KVA, 380V for above 10KVA), adjust the current relay (-KA), current multiplier switch, voltage relay (-KV), and voltage multiplier switch action values and multipliers as needed, and also set the time relay action value.



(2) Apply power, green light (-HL2) lights up. When the voltage regulator handwheel is at zero position, yellow light (-HL1) lights up, and power can be applied for operation.



(3) Press the power-on button (-1SB), main contactor (-KM) engages, voltage regulator (-TD) is energized, green light (-HL1) goes off, red light (-HL3) lights up, speaker emits alarm sound, and (-HL5) flashes. After a delay of 10-15 seconds, the sound and light stop automatically, and the test can be carried out.



(4) Rotate the voltage regulator handwheel clockwise, watch the voltmeter (-PV) indication, increase voltage at a rate of less than 3KV per second. When the required value is reached, press the timing button (-1SB1) and closely monitor the test object.



(5) When using the operation console, if overvoltage occurs during voltage increase or withstand voltage test, the voltage relay (-KV) operates, sound and light alarm, then rotate the voltage regulator handwheel counterclockwise to reduce to the required test voltage.



(6) During voltage increase or withstand voltage test, if overcurrent occurs due to short circuit, flashover, breakdown, etc., the current relay (-KA) operates, the voltage regulator automatically cuts off power, indicating that the test object is unqualified.



(7) After reaching the set withstand voltage time, the time relay (-KT) engages, the speaker emits an alarm sound, indicating that the test object is qualified. At the same time, rotate the voltage regulator handwheel back to zero position, the sound and light alarm stops, press the power-off button (-2SB), disconnect the timing button (-1SB1), and only after cutting off the power can the equipment be disassembled or the test object replaced (for DC tests or large-capacity test objects, full discharge is also required).
