1. For transformers of various voltage levels, the no-load current is 4-9% and the impedance voltage is 4-10%.
2. Control the existing specifications and operating time of the control part.
Note: Can be matched according to user requirements
Feature:
1. The design concept, material selection, and process flow are all brand new, so not only is it small in size, light in weight, and beautiful in appearance, but all technical indicators have met the requirements of JB3570-98 standard.
2. Made using a completely new process, the dielectric insulation material used is completely different from other products, resulting in a product with no partial discharge effect.
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.
