新型继保校验仪
摘要：
本实用新型公开了一种新型继保校验仪，属于测试技术领域。该新型继保校验仪包括：外壳、安装在外壳上的电源开关、安装在外壳里面的保护装置、安装在外壳上面的电流输出端子、安装在外壳上面的电压输出端子，所述校验仪里面的电路包括：电流输出电路和电压输出电路，计量仪表设计在校验仪内部，减少测试外回路的接线，同时选取继电保护二次回路校验中最常用的两种电压档即50V接近相电压档和100V为线电压档，节约成本。本实用新型操作简便，重量轻，功能强且没有多余的功能，接线简单，价格便宜。
摘要（英）：

The utility model discloses a novel relaying check meter, which belongs to the technical field of test. The novel relaying check meter comprises a casing, a power switch installed on the casing, a protecting device installed in the casing, a current output terminal installed on the casing and a voltage output terminal installed on the casing, and the circuits in the check meter comprise a currentoutput circuit and a voltage output circuit. A metering device is designed in the check meter, the wiring of the external test loop is reduced, and simultaneously, the two voltage levels most commonlyused in relaying secondary loop test, namely, 50V which is close to the phase voltage level and 100 V as the line voltage level, so as to save the cost. The novel relaying check meter has the advantages of simple operation, light weight, strong but no redundant functions, simple wiring and low price.
