Rơ le hơi, Gas relay, QJ1-25TH, QJ1-50TH, QJ1-80TH, QJ1-25ATH, QJ1-50ATH, QJ1-80ATH

Flow rate range 1.0m/s  
factory setting 1.0m/s  
1. Relay pipe diameter: 
SXX6-QJ4-25 type is ф25, 
2. Relay working temperature: -30° 

C- +95°C 3. Signal contact action gas capacity: 250-300cm3 

4. Contact rated capacity: 220V 0.3A, 110V 0.6A (S 5X10 S) 

5. Insulation strength: 2000V/nim 

6. Sealing performance: relay It is filled with transformer oil and pressurized at 200Kpa/20min at normal temperature without leakage. 

7. Seismic resistance: When the vibration frequency (positive Hong wave) is 4-20 Hz and the acceleration is 4g, the relay does not malfunction. (g is gravitational acceleration) 

leads can lead the bleed valve with light gas to the main transformer (with a lead box)
