Description

Gas Relay (Double Float-ball Type) for Oil-immersed Transformer QJ9-25A,50A QJ10-80A

Product Overview

The gas relay is a protective device for oil-immersed transformers. It is mounted on the connecting pipe between the transformer tank cover and the oil conservator, and can be fitted with an air guide pipe to facilitate on-ground gas venting and oil sampling. When an internal transformer fault causes oil decomposition to generate gas or triggers surging oil flow, the relay contacts actuate to close the designated control circuit, promptly issuing an alarm signal or automatically cutting off the power supply to the transformer.

Operating Conditions

Permissible operating temperature: -40°C to +105°C

Installation method: The axial line of the relay pipeline shall be parallel to the transformer tank cover. The end leading to the oil conservator may be slightly elevated, with the inclination of the axial line relative to the horizontal plane not exceeding 4%.

Technical Parameters


Seismic resistance: The relay will not malfunction under sinusoidal vibration at a frequency of 4–20 Hz and an acceleration of 4g.
Ingress Protection (IP) Rating: IP55.
Note: The product is inherently rainproof. A rain shield for special applications is sold separately.
Sealing performance: No leakage shall occur when the relay is fully filled with transformer oil and pressurized to 200 kPa at ambient temperature for a continuous duration of 20 minutes.

Contact Capacity
AC 220 V 3 A
DC 220 V 1 A
