Product Description
Henan New Electric Power Co., Ltd. is mainly engaged in the R&D, manufacturing and sales of various medium, high and Low Voltage Transformers and Transformer Accessories. The transformer accessories mainly include Buchholz Relay, Tap Changer , oil level gauge, butterfly valve, Moisture Absorber, pressure reducing valve, Cross Flow Cooling Fan, Bimetal Thermometer, Epoxy Resin Insulator, etc. Welcome new and old customers to purchase and customize. The role of the tap changer is to adjust the number of turns of the transformer's high-voltage winding when the transformer is powered off, so that it changes within the range of+5%~- 5% of the rated value, thus changing the voltage at the low-voltage side to fully meet the user's voltage demand. Off circuit tap changer is applicable to three-phase Oil Immersed Transformer.
Off circuit tap changer is a kind of switch, which is applicable to three-phase oil immersed transformer with rated voltage of 10KV and rated current of 63A or below 125A. Under no excitation conditions, the secondary voltage can be adjusted by changing the turns of the transformer's primary coil. The minimum temperature of tap changer in oil medium is - 25 ℃, and the maximum temperature is 100 ℃.
The structure of off circuit tap changer is composed of drum, cage, bar, disc and wedge. The fixed contact of the strip switch is installed on the long insulating column or insulating plate, and the moving contact moves in a straight line along the direction of the insulating column to change the tapping position.
