high voltage testing transformer
I. General
YDQC Serial light-duty AC/DC high voltage testing transformer is an improved new product based on similar YDJ (G) type high voltage testing transformer, according to the requirements in national standard ZBK41006-89 on testing transformers. This serial product is small, light, structure-compact, function-complete, convenient to operate, applicable to dielectric strength test at power frequency and DC leakage test for high voltage electric equipment, elements and insulation material in electric power departments, industrial and mining enterprises, scientific research departments and other departments. It is a necessary instrument in high voltage tests.
II. high voltage testing transformer Structure
YDQC Serial light-duty high voltage testing transformer is single frame type. Coils adopt concentric cylinder multilayer pagoda-type structure, primary low voltage winding is coiled on core, secondary high voltage winding is coiled outside low voltage winding. This concentric arrangement reduces coupling loss between windings. High voltage silicon stack is packed in sheath with special techniques. Housing is made as octagon structure well fitting internal elements, integral overall appearance is beautiful. The internal and external structure is shown in Fig.1.
1-pressure balance ball; 2-silicon stack short circuit rod; 3-high voltage sheath; 4-oil valve; 5-housing; 6, 7-voltage regulation input terminal a, x; 8, 9-instrument measuring terminal E, F; 10-high voltage tail X terminal; 11-ground terminal of transformer housing; 12-high voltage output A terminal; 13-high voltage rectification silicon stack; 14-internal pressure balance ring; 15-reansformer core; 16-primary low voltage winding; 17-measure instrument winding; 18-secondary high voltage winding; 19-transformer oil.
