1.System Introduction
HZBZ-IV automatic comprehensive test system is technically used for routing testćtype test and special test of transformers, including automatic test capability for ratio-voltagećdirect?current?resistancećno-load?loss?measurementćinduced?over?voltage?withstand?testćtemperature?rise?test (11ļ½33kV class distribution transformer). All the test items can be operated by the relevant transformer automatic comprehensive test system.
The fully automatic model adopts PLC as the control core and industrial control computer as the man-machine interaction interface, which has the outstanding advantages of high reliability, intuitive interface, simple operation and perfect protective measures.
