摘要

PPROBLEM TO BE SOLVED: To safely, rapidly, easily and reliably inspect whether wiring connection of an integrating wattmeter to a main circuit using a current transformer and a load is correct or wrong, as it is, without having to remove the wiring connection and without the need for large-scale power supplies and loading devices. PSOLUTION: While the power normally supplied to the main circuit is cut off, as it is, without removing the wiring connection of the integrating wattmeter to the main circuit, and the current transformer for meters and a load, a prescribed inspection reference voltage is applied, from the body of an inspection device to the metering object circuit, to allow an inspection reference current to flow, voltage waveforms and current waveforms detected by voltage and current terminals, respectively, in the integrating wattmeter to be connected are compared, in terms of reference waveforms created by the body of the inspection device and phase differences and sizes thereof, thus determining whether the wiring connection of the integrating wattmeter is correct or wrong by a control section of the body of the inspection device for display.

要解决的问题：为了安全，迅速，轻松且可靠地检查使用电流互感器和负载的积分功率计到主电路的接线连接是否正确，而不必拆除接线连接，无需大型电源和负载设备。

解决方案：在不断开积分瓦特表与主电路以及仪表和负载电流互感器的接线的情况下，正常情况下切断通常提供给主电路的电源，但要提供规定的检查参考从检查装置的主体向计量对象电路施加电压，以使检查基准电流流动，比较要连接的积分功率计中分别由电压端子和电流端子检测到的电压波形和电流波形，根据检查装置的主体所产生的参考波形及其相位差和大小，从而由检查装置的主体的控制部分确定积分电度表的接线是否正确。
