Test transformer control box
The test transformer control box has the characteristics of convenient use and maintenance, superior performance, safe and reliable use, beautiful appearance, sturdy and 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, with a full Chinese interface, simple and clear operation. After all test items are set, the test is automatically carried out 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 set the time relay action value at the same time.
(2) Turn on the power, the green light (-HL2) lights up, when the voltage regulator handwheel is at zero position, the yellow light (-HL1) lights up, and power can be supplied for operation.
(3) Press the power supply button (-1SB), the main contactor (-KM) engages, the voltage regulator (-TD) is energized, the green light (-HL1) goes out, the red light (-HL3) lights up, the speaker emits an alarm sound, and the alarm light (-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 the 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, during the voltage increase or withstand voltage test, if overvoltage occurs, the voltage relay (-KV) operates, sound and light alarm, at this time rotate the voltage regulator handwheel counterclockwise to reduce to the required test voltage.
(6) During the 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 tested 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 tested object is qualified. At the same time, rotate the voltage regulator handwheel back to zero, 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, sufficient discharge is also required).
