Gas relay

Gas relay (also known as gas relay) is a kind of protection device used in transformers. It is installed in the pipeline between the oil pillow and the fuel tank of the transformer. When the internal fault of the transformer is used to decompose the oil to generate gas or cause the oil flow to surge, The contact of the gas relay acts, turns on the specified control loop, and promptly issues a signal warning (light gas) or activates the protection component to automatically remove the transformer (heavy gas).
The gas relay is divided into a carrier gas relay (the fuel pipe radius is generally 50mm or 80mm) and the body gas relay (the fuel pipe radius is generally 80mm). Gas relays are available in different types such as float type, baffle type, and open cup type. For example, in the QJ-80 type relay, the signal circuit is connected to the open cup, and the trip circuit is connected to the lower baffle. The so-called gas protection signal action means that the signal circuit contacts of the upper open cup in the relay are closed due to various reasons, and the light plate light is on.

Cap Slip Ring

There are a few different types of slip rings, but the most common type is called a cap slip ring. Cap slip rings have a cylindrical housing with an internal flange that fits over the end of the shaft. They typically have 6 or 12 channels and are available in a wide range of sizes.


Cap slip rings are used to provide electrical power and signals to and from rotating equipment. The channels on the slip ring allow for the passage of current and/or data signals through the ring. This allows for the rotation of devices such as antennae, radar dishes, and wind turbines without having to interrupt or disconnect the power or signal lines.


Cap slip rings are very reliable and can handle high speeds and heavy loads. They are also easy to install and maintain.

In the modern world, companies are always looking for ways to improve the efficiency of their machines and operations.
