Application
The products that coupled with electrical alarm signal realize remote control.
The products are apt for electrical equipments such as gas or liquid insulate transformer, instrument transformers, on-load-tap channel switch, high voltage switch etc.
Once there's something wrong in such electrical equipments, valve open and relieve the pressure to avoid oil basin from metamorphose and blowout.
With the pressure reduced the valve automatically closed to prevent water and impurity got in from outside.
Working conditions and install mode:
Environment temperature - 30º C~40º C
Installation site
A) Install in the oil basin to cover
B) Install in the oil basin to sidepiece upside
C) Install in lift pedestal Alarm and Enviroment
Install, Using, Debugging Install: Pressure releasing valve and tank connect with the stud bolt
Attention: 1) The bottom of pressure releasing valve assemble to seal well;
2) When connect the pressure releasing valve and tank, tighten the bolts equality, avoid that valve pedestal rupture.
L Using: With latching that must be removed before equipment circulate;
Insure the normal work of the pressure releases valve.
L Debugging: Electric alarm switch, should manual debug deferent signal of switch whether exactitude, sensitive, before the equipments circulate.
L Method: 1)Measure export signal of switch when pressure releasing valve action less by multimeter to see whether in accordance with the signal mark of the switch.
Viz.: (a) "Common" towards "Normal open" normal open
(b) "Common" towards "Normal closed" normal closed.
2)Experiment of simulate releasing valve's action, checkout whether inching switch accurate export behavioral signal. Method: Raise the small red hat of the pressure releasing valve, then releasing valve turn on, check whether the switch measure of the electric signal change.
Viz.: (a)"Common" of switch towards "Normal open": "Normal open" should turn to "Normal closed" (b)"Common" of switch towards "Normal closed": "Normal closed" should turn to "Normal open"; (c)Examine the signal switch and control circuit connect whether right and good. L Attention: The small red hat must be replacement after test over, insure that the pressure releasing valve normal working and warning.
