通过出线电压互感器实现扩大内桥电压并列

Expanding the inside bridge voltage paralleling by main lead voltage transformer

考虑到简化一次电气元件配置的目的。主接线采用了只配置两路出线三相电压互感器，不配置母线电压互感器的接线方式，二次上配置电压并列装置，母线电压由进线电压经过重动回路生成。对原电压并列回路进行改进。

Main wiring configured three - phase potential transformer instead busbar potential transformer for simplifying the primary system. Secondary system configured voltage paralleling device, and incoming voltage transited the reset circuit and formed busbar voltage. Voltage coordinate circuit was improved.
