Product Description

Characteristics of the product
Through the automatic capacity adjustment, the unreasonable state of the transformer trolley is avoided.
Through the adjustment of capacity, the transformer no-load loss can be reduced by 50%-70V, the reactive power loss of power supply network can be reduced by more than 20%, and the reactive power line loss can be reduced by more than 20%.
The switching process of the capacitor switch is completed within 20ms-40ms, maintaining the continuity of the power supply on the low voltage side.
Scope  of  application
1 Suitable for rural power grid with large seasonal load variation range.
2 Suitable for some urban business districts, development zones, industrial zones and other areas with significant diurnal load changes.

Note:1.The parameters in parentheses arefor small capacity.2.Other cornection groups and corresponding technical parameters are non-preferred parameters,which are negotiated by the user andthe manufadurer.3.Accordingtouser needs,a distnibution transformer with ahigh-voltage tapping range of±2×2.59%or other tapping ranges can be provided.
There is an impedance in the transformer, and in the power transmission, the voltage drop will be generated and will change with the change of the user side load. The fluctuation of the system voltage and the change of the user side load will cause a large voltage change. Under the premise of realizing the local balance of reactive power, when the voltage change exceeds a certain value, the on-load regulator will act after a certain delay to adjust the voltage and keep the voltage stable.
