(2) sense terminals is placed on successively needs near the detection line termination voltage probe to be received respectively on the A/B/C/N, current clamp is clamped the A/B/C threephase cable respectively;
Two, detect:
(1) opens the switch of main website and each terminal, set cable number (as No. 1), begin to detect.Through detection after a while, at the display screen of main website demonstration is connected on termination number on this circuit, this terminal display screen is numbered circuit, and this wireline inspection is finished;
(2) will detect main website and receive (as No. 2 circuits) on another circuit, repeating step 1), up to distinguishing whole circuits, this detects end.
(3) can write down testing result (the terminal number data of circuit number correspondence, circuit number need manual input) in the main website detector automatically;
Three, points for attention:
(1) careful record:
Installation and measuring equipment will write down main website institute's Line connecting number and each terminal position, reads main website checkout equipment video data and will in time write down and circuit be indicated;
(2) if having many wireline inspection to come to the same thing and can't confirm, please select multiparameter to detect, and proper extension detection time.
Claims (2)
