过电流继电器是继电保护装置的一种，当负载电流超过整定值时，继电器动作。

An "Overcurrent relay" is a type of protective relay which operates when the load current exceeds a preset value.

应经常检查高压直流电源内电流继电器，时间继电器的整定值是否正确，控制是否灵敏。

We should always check the high voltage DC power supply within the current relay, time relay setting value is correct, control is sensitive.

此整定原则以正常偏大方式整定电流、电压定值，其目的是在保证保护可靠性的前提下，增大瞬时速断保护的保护范围。

The new principle calculates current and voltage setting values, which are greater than normal values, to increase protection scope under the condition of assured protection reliability.
