一种电能表抗接地故障抑制试验与准确度联合检验装置
摘要：
本发明公开了一种电能表抗接地故障抑制试验与准确度联合检验装置，包括PC上层控制系统、底层控制模块、误差计算模块和现场校验仪；所述PC上层控制系统分别与底层控制模块、误差计算模块、现场校验仪连接，所述现场校验仪与待检验电能表连接，所述PC上层控制系统对所述底层控制模块发送控制指令，所述底层控制模块与待检验电能表连接，根据接收所述PC上层控制系统的控制指令控制所述待检验电能表的检定状态，所述误差计算模块与待检验电能表连接，计算所述待检验电能表抗接地故障抑制试验前后的误差数据，并传送至所述PC上层控制系统。所述PC上层控制系统通过判断故障前后电表的误差改变量是否在允许的范围之内检验电能表抗接地故障抑制能力。
摘要（英）：

The invention discloses an electric energy meter anti-earth fault inhibition test and accuracy combined verifying device comprising a PC upper layer control system, a bottom layer control module, an error computing module and a field check meter; the PC upper layer control system is respectively connected with the bottom layer control module, the error computing module and the field check meter; the field check meter is connected with a to-be-tested electric energy meter; the PC upper layer control system sends a control order to the bottom layer control module; the bottom layer control module is connected with the to-be-tested electric energy meter, and controls the detection state of the to-be-tested electric energy meter according to the control order of the PC upper layer control system; the error computing module is connected with the to-be-tested electric energy meter, computes the error data before and after the to-be-tested electric energy meter anti-earth fault inhibition test, and sends the data to the PC upper layer control system; the PC upper layer control system determines whether the error change amount of the electric energy meter before and after the earth fault is within the allowable scope or not, thus verifying the electric energy meter anti-earth fault inhibition capability.
