| Zusammenfassung: | The invention provides a remote signaling loop matching resistance screening and quality control method. The method comprises the steps that S1,components are selected,the matching resistance value iscalculated,and a remote signaling loop circuit board is manufactured; S2,the remote signaling circuit board is installed on a relay protection device,the relay protection device is connected with anupper computer through the Ethernet,communication between the relay protection device and the upper computer is achieved,and the voltage value of remote signaling deflection can be sent to the upper computer in real time; S3,a power supply of the relay protection device is switched on,the remote signaling circuit board is connected with a test power supply,the output voltage of the test power supply is adjusted,and a corresponding remote signaling deflection voltage value is obtained; S4,data is arranged and analyzed to obtain a reasonable matching resistance value,a high-low temperature testis carried out,and a neural |
