本装置主要由功率测量回路、电压测量回路、失压报警指示回路组成。功率测量回路采用FS—15三相有功功率变送器,把强信号变成模拟量输出,进行远距离输送至“电调”,在“电调”由FS—16功率总加器,实现分散和集中叠加数字显示;电压测量回路,主要采用FS—14交流电压变送器,把强信号变成模拟量,进行远距离输送,在“电调”各路电压分别数字显示;失压报警指示回路、主要靠自制“失压晶体管继电器”和“晶体管冲击继电器”实现失压报警指示。这套装置除FS—14、FS—15装在各总降压变电所,其余装在“电调”,电调值班人员可以通过这套装置很方便的监视全厂和各条线路负荷变功情况和电压波功程度。为合理用电、节约电能提供科学依据。
The device mainly by the power measurement circuit, voltage measurement circuit, pressure loss alarm circuit instructions. Power measurement circuit using FS-15 three-phase active power transducer, the strong signal into an analog output for long-distance transmission to the “ESC” in the “ESC” by the FS-16 power totalizer, to achieve decentralized And focus on the superimposed digital display; voltage measurement circuit, the main use of FS-14 AC voltage transmitter, the strong signal into an analog, long-distance transmission, the “ESC” the voltage of the digital display, respectively; Circuit, mainly by self-made “loss of pressure transistor relays” and “transistor impact relay” to achieve pressure loss alarm instructions. This set of devices in addition to FS-14, FS-15 installed in the total step-down transformer substation, the rest installed in the “ESC”, ESC staff can easily monitor the entire plant through the device and the various lines load change Work conditions and voltage wave power level. To provide a scientific basis for rational use of electricity, saving electricity.
