高压双电源互投控制应注意开关“防跳”

Precautions Against“Surtch-Jumping”in the High-Tension Double-Power Supply Change-over Control

在实际工程中发现高压双电源互投回路主开关的“防跳”控制设置不完善，文中阐述了其前因后果，并对典型控制回路提出了改进建议．

In the real engeering projects,it is impeofect to control the “main suitch-jumping”in the return-circuit of high-tension double-power supply change-over control.This arbicle elaborates its cause and etfeet,puts forward suggestions on typical return-cicuit device to improve the power supply.
