Abstract
A terminal voltage compensation device is arranged between an output port of a low-voltage side and a terminal user and connected with a main control circuit in parallel and mainly comprises a transformer, an alternating-current chopping unit and an output filter. The output port of the low-voltage side is connected with the transformer in series, the transformer is connected with the alternating-current chopping unit and the output filter in series sequentially, and the output filter is connected with the terminal user. The terminal voltage compensation device is simple, small and portable in structure, easy to operate, convenient in installation and construction, easy in manufacturing process, low in production cost and high in stability. As the maximum boosting range of output voltage is 140%-150% of that of input voltage, the input voltage has wider applicable range, no-load and load loss is low, and extension of 10kV lines and adding of conventional transformers are omitted. Accordingly, the terminal voltage compensation device is suitable for some transformer districts with failure in normal power utilization for the terminal user and with lower voltage quality rate due to overlong lines.
