On-load tap position indicators for power transformers ShchUP120

SHUP120 pointers are designed to convert the signal of sensors of switching devices of transformers under load into a digital signal; digital indication of tap changer control stage and arrow pointer replacement; transmission of information about the position of the drive via digital interfaces and analogue outputs to ACS; signalling for relay protection and automation. The pointers are used in various industries, at substations with voltage 35-750 kV with smoothly or sharply changing load, as well as at generating stations together with drives of Bulgarian, German and Russian production. They are suitable for installation on drives MZ-2, MZ-4, on drives of MR, EM and ED-S types, as well as on any other drives with resistive sensor or with a sensor having an output signal of "current loop" type 4...20 mA, 0...5 mA, 0...20 mA and the number of stages not more than 99. ShchUP120 work together with the selsin-sensor of the angle of rotation of the actuator type BD404, BD1404 and are suitable for installation on all actuators....
