Abstract

The invention provides a signal remote transmission gas relay. According to the technical scheme, the external structure of the gas relay is improved, and meanwhile, the image acquisition module is introduced. Specifically, the bottom face of the containing cavity is designed to be the inclined face so that one-way movement of oil can be guaranteed, and meanwhile the middle partition plate is additionally arranged so that large fluctuation can be avoided in the oil flowing process. On the basis, the camera is additionally arranged at the top of the device, a liquid level image can be transmitted to a background in real time and remotely monitored by a worker, and frequent on-site checking actions are omitted. In addition, the sleeve is used for protecting the binding post, and a circuit can enter and exit from the side end; and during maintenance, the flange cover at the upper end can be opened, so that the installation and maintenance of the equipment are not influenced. According tothe invention, the oil level monitoring efficiency of the gas relay is improved, and a more perfect protection structure is provided.

Description

Technical field[0001]The invention relates to the technical field of Buchholz relays, in particular to a signal remote transmission Buchholz relay.Background technique[0002]Buchholz relay, also known as gas relay, is a protection device used in transformers. It is installed in the pipeline between the oil conservator and the oil tank of the transformer. The internal fault of the transformer causes the oil to decompose and generate gas or cause the oil flow to surge. The contact action of the gas relay connects to the designated control circuit, and promptly sends out a signal alarm (light gas) or activates the protective element to automatically cut off the transformer (heavy gas).[0003]The light gas mainly reflects that the gas decomposed by the oil rises into the gas relay during operation or minor faults. The air pressure causes the oil level to drop. The open cup of the relay drops with the oil surface, and the light gas reed contact is connected to send a signal. When there is ...
