Our company's oil immersed on load and off load tap changer has the characteristics of simplicity and practicality, High quality materials ensure an ultra long service life, All product type tests exceed existing international standards, The product...
Tap Changer shall be used for tap changer and connection of coil equipment. It is divided into off circuit tap changer and on load tap changer.
The power transformer has ± 5% tap. The connection of the tap is changed through the tap changer to change the turns of the high-voltage coil, so as to adjust the output voltage of the transformer.
Off load 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 product categories are divided into: disc switch, strip switch and cage switchOn load tap changer refers to a voltage regulating device suitable for operation under excitation or load of transformer and used to change the tap connection position of transformer winding. Its basic principle is to realize the switching between taps in the transformer windings without interrupting the load current, so as to change the number of turns of the winding, that is, the voltage ratio of the transformer, and finally achieve the purpose of voltage regulation.
Note:
Please clearly describe the required voltage, current and voltage regulating gear to the staff when purchasing tap changer, otherwise we will not be able to provide you with a quotation
