Product Description
A Tap Changer is a device that adjusts the voltage of the coil of a power transformer. It is used to change the tap of the primary or secondary winding, change its effective number of turns, and perform graded voltage regulation. It is divided into no-load tap changer and on-load tap changer. The former is used for manual operation after a power outage, while the latter is used for electric operation under live conditions. The no-load tap changer generally has 3-5 taps. The contacts of the tap changer are made of nickel plated brass, which has the characteristics of wear resistance and good conductivity. The commonly used contact structures include circular contacts (cylindrical fixed contacts) and clip type contacts (knife shaped fixed contacts). On load tap changer generally has 7-15 taps. It consists of a switching switch (with a fast mechanism), a selection switch, a range switch, and an operating mechanism The role of the tap changer is to adjust the number of turns of the high-voltage winding of the transformer to change within the range of+5%~- 5% of the rated value in the case of power failure of the transformer, so as to change the voltage at the low-voltage side to fully meet the user's demand for voltage. Off circuit tap changer is applicable to three-phase Oil Immersed Transformer.
