XC Test Transformer Control Console
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 that require power maintenance. It adopts advanced microelectronics 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.
Operating Box (Console) Usage Method:
(1) Check whether the main power supply is consistent with the input power supply (below 10KVA is 220V, above 10KVA is 380V), adjust the action value and multiplier of the current relay (-KA), current multiplier switch, voltage relay (-KV), and voltage multiplier switch as needed, and set the action value of the time relay at the same time.
(2) Send power, the green light (-HL2) is on, when the voltage regulator handwheel is placed at zero position, the yellow light (-HL1) is on, and power transmission operation can be performed at this time.
(3) Press the power transmission button (-1SB), the main contactor (-KM) is engaged, the voltage regulator (-TD) is energized, the green light (-HL1) goes off, the red light (-HL3) is on, 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 indication of the voltmeter (-PV), increase the voltage at a speed of less than 3KV per second. When it rises to the required value, press the timing button (-1SB1) and closely observe the condition of the test object.
(5) When using the operating console, during the voltage increase or withstand voltage process, if overvoltage occurs, the voltage relay (-KV) acts, and 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) acts, and 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) is engaged, and 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 be replaced (for DC tests or large-capacity test objects, full discharge is also required).
