定期检验方法

说明:

过流继电器正常运行时无需进行任何操作，但为了确保继电器的正确动作,请定期地使用功能检验按钮对其动作情况进行确认，以确保动作正确无误。每年的定期检验可按以下方法进行：

1、由试验电流源将接地试验电流引入ZCT的一次侧，对动作值进行测定。

2、在过流继电器的监控回路内，通过开关等人工设置接地回路，对过流继电器的动作情况进行测定。继电器动作值的允许误差：实测值在继电器设定值的51～100%范围内即为正常。(定期检验仅对当前使用中的设定值进行测定确认即可)

Important:

The current relay does not need any operation when it works normally, but to ensure its function correctly, please regularly inspect and confirm its function via the function test button. Annual regular inspection can be conducted as:

1、connect testing ground current from the testing power supply to the primary of the ZCT, measure the operating value;

2、through a switch, manually set up a grounded circuit in the current relay monitor circuit, measure the operation of the current relay. The permissible error of the relay: actual measurement is within 51～100% of the setting value. (regular inspection is only to check the present setting)

备注

该装置多用于系统保护，作漏电接地和分级保护使用，其中DJ-ZBT□3型具有两段报警功能。
订货时请注明剩余电流互感器和剩余电流继电器型号，注意相关参数动作功能是否满足要求。
根据系统保护要求，通过旋钮开关或拨动开关，现场设定剩余动作电流和动作时间。
剩余电流互感器和剩余电流继电器间的联线宜选用屏蔽导线，截面不小于1.5 mm 。
The device is used for multi-system protection, as current leakage and time lag action protection, additionally DJ-ZBT□3has two-stage alarm function.
When ordering, please mark the type of the residual current transformer and relay, also notice that if the related parameters, function are satisfied.
According to the system protection requirements, field set the residual operating current and time through the rotary switch or toggle switch.
The wiring harness for connecting residual current transformer and current relay should be shielded conductors with cross section 1.5 mm minimum.
