产品描述
NKB-33X Gear transmitter can be used to monitor the load-regulating state of substation transformer, according to the shift position of the splitter switch into a step ratio of the analog DC voltage, by the conventional RTU or other acquisition device received, become the automatic telemetry system of the front non-power conversion equipment. The transmitter uses a variable potentiometer synchronized with the tap-changer and a three-wire bridge to transmit the voltage regulating signal to the transmitter, after the special circuit conversion, the output and the gear corresponding to the step analog current/voltage signal, each gear transmitter can measure a point contact switch, input, output completely isolated.
Characteristics
●Measuring gear position
