The dry-type rectifier variable frequency transformer is designed to provide a multi-phase rectified power supply for medium and high-voltage frequency converters. This product is mainly used in power plant boiler fans, water supply systems, and automated control systems in the metallurgical and chemical industries and urban municipal engineering.

Our company applies mature technology, fully considers various types of medium and high voltage frequency converters, and carefully develops and develops ZPSG type NOMEX insulated thousand-type rectifier variable frequency transformers. Products include 9-phase, 12-phase, 18-phase, and 27-phase self-cooling and air-cooled rectifier variable frequency transformers.

This type of transformer has the remarkable characteristics of small size, strong overload capacity, small partial discharge, strong short-circuit resistance, natural resistance, low noise, and 40% power saving.

Product Features:

1. The iron core adopts a through-core positioning structure with multi-stage stepping technology. The iron core has no lateral or longitudinal displacement under various working conditions.

2. The winding adopts various structural types and has strong short-circuit resistance.

3. Adopting a special air-cooling diversion system, it has high heat dissipation efficiency, safety, and reliability.

4. The magnetic flux leakage is reasonably distributed and fully meets the working condition requirements of the inverter.

5. Use multiple technologies to effectively suppress harmonic content, achieve perfect harmonic-free performance, and extend the service life of the motor.

6. Various structural types can meet the requirements of various frequency conversion systems.

7. The maximum capacity of the product can reach 9000kVA and achieve 72-pulse rectification.
