Description

Technical Field

[0001] The invention relates to the technical field of gas relays, and in particular to a signal remote transmission gas relay based on heavy gas action recognition. Background Art

[0002] A gas relay, also known as a gas relay, is a protective device used in transformers. It is installed in the pipe between the oil storage cabinet and the oil tank of the transformer. When an internal fault of the transformer causes the oil to decompose and produce gas or causes oil flow surge, the contacts of the gas relay will be activated, the designated control circuit will be connected, and a signal alarm will be issued in time (light gas) or the protection element will be activated to automatically cut off the transformer (heavy gas).

[0003] Heavy gas is mainly reflected in the strong gas generated by serious internal faults of the transformer (especially inter-turn short circuit and other faults that cannot quickly act on other transformer protections). The strong gas pushes the oil flow to impact the baffle, and the magnet on the baffle attracts the heavy gas reed contacts, causing the contacts to connect and trip. Heavy gas is a liquid. When the amount of heavy gas is too much, the valve plate of the bottom valve is pressurized to a threshold value and then opens, allowing the liquid to flow out of the pipeline. The discharge of heavy gas is currently mainly observed by the naked eye of the staff, which not only takes up a lot of manual energy, but also makes it difficult to ensure that problems are discovered in the first place. Summary of the invention
