YDQW Series Inflatable No Partial Discharge Test Transformer

Product Introduction:

Used for manufacturers of electrical appliances, cables, motors, transformers, mutual inductors, insulation materials, and related high-voltage components, as well as high-voltage testing laboratories in power, scientific research, and universities, to conduct partial discharge and power frequency withstand voltage tests on their products.

Technical parameters:

Özellik:

1. Filled with SF6 gas, which features high insulation strength, as the insulating medium.

2. Compact and lightweight design with high-quality craftsmanship, attractive appearance, and easy handling.

3. Benefiting from the arc-extinguishing properties and specialized structural design involving SF6 gas, the unit exhibits low partial discharge levels, measuring ≤5 PC at rated voltage.

4. The testing process is simple, intuitive, and user-friendly.

5. Effectively eliminates clutter interference from the power supply.

6. Integrates automatic control technology, offering a high degree of automation and strong anti-interference capability.

7. Equipped with a fast-acting electronic protection device, ensuring high reliability.

Working principle:

The control panel (box) with overcurrent automatic tripping and zero position interlocking device to prevent sudden pressurization of the power input is regulated by an autotransformer to input voltage into a non partial discharge filter isolation filter transformer, and then output from the non partial discharge filter isolation filter transformer

To test the primary winding of the transformer, according to the principle of electromagnetic induction, the secondary (high voltage) winding can obtain an equal multiple of voltage amplitude - power frequency high voltage - based on the ratio of its turns to the primary winding.
