0.0 0.0
Product description

QYDQ (J/Z) series gas-filled test transformers use sulfur hexafluoride (SF6) gas as the insulating medium. It is a replacement product of oil-immersed light test transformers and dry test transformers. It can be widely used for AC and DC withstand voltage test of various high voltage power equipment of power system users. Especially suitable for use in the wild and plateau mountainous areas.

Product Features

1. It has small size and light weight (it is 20%-60% lighter than oil-immersed light test transformer)

2. No oil pollution, not affected by climate change

3. The corona level is small, the rated voltage partial discharge is ≤3PC, and the 80% voltage partial discharge is ≤2PC

4. On-site transportation does not need to be static and can be tested, has a long service life, and does not require maintenance.

5. The highest voltage level of a single device can reach 300KV

6. Continuous operation is allowed for 0.5 hours at rated voltage and rated power, and continuous operation is allowed at 2/3 of rated current

7. Over-voltage protection: the complete set of equipment should have reliable over-voltage protection function to prevent the occurrence of over-voltage

Product parameter

1. Voltage level: 10kV~600kV

2. Capacity range: 1~500KVA

3. No-load current: <7%

4. Impedance voltage: <8%

5. Product type: AC, AC and DC, AC cascade, AC and DC cascade
