资料介绍

针对照明控制电路中存在负载供电不连续和调压变压器大体积高成本的问题,本文设计了一种用于道路照明的有载调压控制电路。该电路所接负载供电电压主要来自于电网电压,变压器只提供调压电压,可通过控制电路开关改变所连接变压器的初级线圈串并联结构及数量,从而调节电压的大小及精度。实际运行结果表明,该基于道路照明的有载调压控制电路不仅确保负载供电的连续性,同时大大减小变压器体积,降低使用成本,较好地实现预期节电目标。

Aimed at the problems of uncontinuous power supply to the loads and large volume, high cost of transformer in the lighting control circuit, this paper designs an OLTC control circuit used in road lighting specially. In this OLTC control circuit, the power supply to the loads is not from transformer but grid directly, while the transformer in the circuit only provides adjusted voltage. By changing the circuit's series or parallel structure and the transformer's primary coils quantity through the switches in the circuit, the value and precision of voltage can be adjusted. The actual running results show that the OLTC control circuit can not only ensure continuous power supply to the load but also decrease the transformer's volume and cost....
