9. Time fully computer-controlled, stop conditions can be arbitrarily set, time range can be set from 1 second to 100 minutes.
10. Small size and light weight, dozens of times lighter than traditional equipment of the same capacity.
11. High-voltage winding is multi-layer pagoda trapezoidal structure, low-voltage winding is cylindrical structure, shielding and core are grounded together.
12. The bottom of the oil tank is equipped with movable casters (no casters below 5kVA), can be moved freely on the ground, convenient for laboratory and field operations.
13. The ultra-light test transformer is indoor equipment, the iron core uses high-quality cold-rolled grain-oriented silicon steel sheets, the structure is core type, horizontally placed, with low-voltage winding, measuring winding, shielding, and high-voltage winding concentrically mounted on the core column.
Test Transformer Parameters
1. Maximum relative humidity of air: when the air temperature is +25℃, the relative humidity does not exceed 90%.
2. When using the ultra-light test transformer, the input voltage should be gradually increased, and reliable protective measures should be taken.
3. Waveform of power supply voltage: the waveform of the power supply voltage is actually a sine wave, frequency is 50Hz, and the power supply side should not suffer from external atmospheric overvoltage.
4. Installation site: the installation site should have no gases, vapors, chemical dust deposits, dirt, or other explosive media that seriously affect transformer insulation, and no places with severe vibration.
5. Ambient temperature: maximum air temperature +40℃, maximum daily average temperature +30℃, maximum annual average temperature +20℃, minimum temperature -5℃ (indoor type), -25℃ (outdoor type).
6. Altitude: the altitude of the transformer installation site should not exceed 1000m. When the altitude exceeds 1000m, the external insulation classification of the transformer is divided into two levels: 2500m (greater than 1000m to 2500m) and 4000m (greater than 2500m to 4000m).
YDQ Series - 5KVA/50KV Ultra-light High Voltage Test Transformer Product Introduction
Ultra-light test transformer is also called test transformer. The ultra-light test transformer is a power testing instrument based on the "Test Transformer National Standard" and the industry standard "JB/T9641-1999", verified and approved by the national power department. As the main unit of high-voltage test equipment, the ultra-light test transformer, combined with control systems, voltage regulators, protective devices, etc., is mainly suitable for power systems, industrial and mining enterprises, scientific research departments, etc., to conduct power frequency or DC high-voltage insulation strength and leakage tests on various electrical equipment, electrical components, and insulating materials. It is used to assess the insulation level of the test object, and can early detect local defects of the test object and measure the ability of the test object to withstand internal and external overvoltages.
