Product Description

Product Description
Advanced Multifunctional Gas Relay with Oil Pressure Monitoring
Annotated examples: QJM-40/30-20-35 represents a fully sealed gas relay with a heavy gas (pressure) relay alarm value of 30kPa, a light gas gas alarm oil level of 20 mm under the tank cap, a pressure release valve opening pressure value of 35kPa, and a pipeline diameter of 40mm (low oil level alarm contact can be added if required by the customer).

Scope of use: (a). Installation position: installed on the top of the lid, or parallel to the lid;

(b). Environmental requirements: -45ºC ~ +70ºC;

Working environment requirements: -45ºC ~ +105ºC;

(c). Relative humidity: +20ºC, not more than 95%;

(d). Contact capacity: AC 250V/3A,

DC 250V/1A;

(e). Insulation voltage: 2000V, 1min.

Gas relay (also known as gas relay) is a protective device used by the transformer, installed in the pipeline between the oil pillow and the fuel tank of the transformer, the use of the transformer internal failure to decompose the oil to produce gas or cause oil surge, so that the gas relay contact action, connected to the control circuit, And timely signal alarm (light gas) or start the protection element automatically cut the transformer (heavy gas). Light gas is mainly reflected in the operation or slight failure of the gas decomposed by oil rising into the gas relay pressure to reduce the oil level, the open cup of the relay falls with the oil level, the light gas dry contact is connected to send a signal, when there is too much gas in the light gas, the gas can be released by the gas relay nozzle. Heavy gas is mainly reflected in the serious internal fault of the transformer (especially the fault that other transformer protection cannot operate such as inter-turn short circuit), the strong gas drives the oil flow to impact the baffle plate, and the magnet on the baffle plate attracts the heavy gas reed contact, making the contact connected and tripping. The gas relay is divided into on-load gas relay (tubing radius is generally 50mm or 80mm) and body gas relay (tubing radius is generally 80mm).
