Product Description
Product Description
Product introduce
The test transformer, also known as the booster, is the equipment for the electrical strength test of power generation and supply equipment, various electrical products and insulating tool materials.
Usage method
1. Single use Before the test, the high-voltage tail end of the test transformer shall be reliably grounded, otherwise the safety of personnel and equipment will be endangered. Be familiar with the electrical principle and use method of the test transformer and power control box before operation. Wire according to the wiring diagram. Preparations and safety measures are ready, and the equipment is air tested once. Connect the tested object. Switch on the power supply, and the power indicator of the control box (console) lights up. Press the closing button, and the closing indicator lights up. Apply voltage evenly clockwise, and watch the voltage amplitude at the stage when the voltmeter reaches and the condition of the tested object until the rated test voltage is reached. Keep the specified withstand voltage time and watch the ammeter and the tested object. When the withstand voltage time is up, watch the kV meter and quickly return the voltage regulator to zero. Discharge through resistance with discharge rod, and then discharge directly to ground. The high-voltage part may be discharged one by one at the charging part, and the high-voltage line lead shall be changed or removed, so far as this (phase) test is terminated
2. Multiple series excitation Overview Our company designs and produces a series of test devices for series excitation combination of several dry-type test transformers. Because the scattered combination can be used conveniently, it can meet various needs on site. The single component is light in weight, easy to transport and move, and the department with higher voltage level can successfully obtain higher test power supply on site. Cascade combination mode A. When two test transformers are connected in series, the capacity ratio of the first and second test transformers is 2:1, and the total capacity is the capacity of the first, The total voltage is the sum of the highest output voltage of two single sets, and the current is the ratio of the capacity to the total voltage. Example: 5kVA/50kV and 3kVA/50kV. Two When the cascade is used, the total capacity is 5 kVA, the total output voltage is 100 kV, and the output current is 50 mA. B. When the three test transformers are connected in series, the capacity ratio of the three transformers is 3:2:1, the total capacity is also the capacity of the first transformer, and the total voltage is three The sum of the output voltages of each set. Note: The output current shall not exceed the rated current of the last level, regardless of the two level string or three level string.
