目前 ,继电保护装置的原理、性能及二次回路在日趋完善、合理 ,而在实际工作中 ,还存在一些问题需要现场工作人员去探讨、解决 ,否则 ,同样会影响保护装置的可靠性 ,危及电网的安全运行。1 直流电源的可靠性直流电源对于保护装置来说是非常重要的 ,它的可靠如果不能得到保证 ,
At present, the principle, performance and secondary circuit of the relay protection device are becoming more and more perfect and reasonable. However, in practical work, there are some problems that need to be discussed and resolved by the field staff. Otherwise, the reliability of the protection device will also be affected, Endanger the safe operation of the power grid. 1 DC power supply reliability DC power supply for the protection device is very important, if its reliability can not be guaranteed,
