Product Introduction

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil.

Characteristic structure

Temperature control system

The safe operation of dry-type transformers and its service life depend to a large extent on the safety and reliability of transformer winding insulation.

cooling method

Dry-type transformer cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, the transformer can run continuously for a long time under the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be kept in continuous overload operation for a long time.

Technical Parameters

2. No-load current: <4%;

3. Compressive strength: 20000V/min without breakdown; testing instrument: YZ1802 withstand voltage tester (20mA);

4. Insulation grade: F grade (special grade can be customized);

5. Insulation resistance: ≥2M ohm test instrument: ZC25B-4 type megohmmeter <1000 V);

6. Connection mode: Y/Y, △/Y0, Yo/△, auto-coupling (optional);

7. Allowable temperature rise of coil: I00K;

8. Heat dissipation method: natural air cooling or temperature control automatic heat dissipation;

9. Noise coefficient: ≤30dB.
