摘要
详细地阐述了应用固态继电器实现有载自动调压的原理,具有调节速度快,改变分接头时不需过渡电阻,冲击电流小,可频繁操作;无电弧产生,可以直接放在变压器油箱中;结构简单,造价低,便于在配电变压器中推广使用。
The principle of transformer with automated regulation by using solid state relay is expounded in detail in the paper. It has high regulation speed, and need not transition resistor, and has low rush current, and is operated frequently; there is no electric arc to be produced and can be put in the fuel tank of the voltage transformer directly; at the same time the structure is simple and the cost is low. It can be used widely among the voltages transformer of distribution.
