8.Installation & Debugging
8.1
．
Relay Installation
8.1.1. The relay core must be taken out and the bandage used to fix in transit be disassembled berore installation
of the relay leaving factory.Check all of the fastenings if they become flexible, if the snap ring(float) and guard
board move flexibly,and if the contacts open and close reliably.
8.1.2
．
The relay should be installed in the pipe connector between an oil-immersed transformer’s oil tank and a
conservator.Internal diameter of the pipe connector should be the same with the relay’s pipe diameter(caliber),and
the arrow on the relay must be directed to the conservator. It is allowed that the conservator end is higher however
the degree of inclination may not exceed 4% between the pipe connector’s axis and level surface or the method for
installation of inclined air fitting pipe may be used so that the gas inside the taansformer can smoothly enter into
the relay.
8.1.3
．
In order to be converient to overhaul the gas relay at site,its installation site needs to guarantee that the
relay’s core may be smoothly taken out of the case.The height for QJ4-25 type to be taken out is 130mm, and that
for QJ4-50 and 80 types 150mm.
8.1.4 .Open the valve in the connecting pipe, take down the gas lock dust cover, and unscrew gas lock nut 2 by
hand (not to take down the nut) after installation to exhaust air till the air nozzle’s oil spill, and then screw down
the nut.
8.1.5
．
Take down blocking screw 4 in the cover of the relay before open the oil valve if it is necessary to connect
with the air dust box, then srew on joint chair 3, and then connect conduct pipe 6 to joint chair 3 with nut 4 and
cushion 5 (please refer to
Fig.2
and
3)
. The gas block in the relay can be normally used after connected with the
air duct box.
