Industrial Microwave Transformers

Applications

A specialised electronic-transformer design for demanding microwave equipment. Used as a power transformer and an isolation/current-stabilising transformer in food processing, pharmaceuticals, chemicals, building materials and other microwave processes.

Operating principle

Also described as a high-voltage constant-current transformer. Magnetic shunts are placed between primary and secondary windings, increasing their insulation separation. The shunt thickness determines current-stabilising performance. The primary operates in the unsaturated magnetic region and the secondary in the saturated region; this is a purpose-designed leakage-flux/leakage-inductance transformer.

Construction and features

Developed for prolonged industrial duty where conventional microwave transformers may overheat or require frequent replacement. Uses quality copper wire, Chinese silicon-steel laminations, automated pressure-welding and CNC winding.

To reduce the temperature rise associated with the saturating magnetic design, the brochure specifies Class H silicon-powder varnish and vacuum impregnation. It describes lower heating, vibration and noise, and a service-life claim of 6–9 times that of an ordinary transformer; this is a brochure claim without comparative test data on this page. It describes compatibility with magnetrons from Panasonic, Samsung and other manufacturers.

Dimensions and customisation

Overall and mounting dimensions are supplied in the user manual. Special dimensions can be manufactured to order.
