Abstract
Description
Technical Field
[0001] The invention relates to the technical field of gas relays, and in particular to a signal remote transmission gas relay. 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] Light gas is mainly reflected in the fact that the gas decomposed by oil rises into the gas relay during operation or minor faults. The air pressure causes the oil level to drop, and the open cup of the relay falls with the oil level. The light gas reed contact is connected and sends a signal. When there is too much gas in the light gas, the gas nozzle of the gas relay can release the gas. When there is too much light gas, the liquid level will drop. When the liquid level drops to a certain level, it may cause danger if timely measures are not taken. In the prior art, conventional gas relays mainly rely on regular observation by personnel to judge the oil level. This mode not only requires frequent inspections, but also makes it difficult to ensure timely detection of problems. Summary of the invention

[0007] Preferably, a circular convex ring is provided on the outer periphery of the front port, the front cover is attached to the convex ring, and bolts penetrate the front cover and the convex ring to fix the front cover and the convex ring.
[0008] Preferably, there are several cameras, and the several cameras are located at different positions on the top surface of the shell.

[0010] Preferably, a strip-shaped notch is provided at the lower end of the middle partition, and the spaces on both sides of the middle partition are interconnected through the notch.
[0011] In the above technical scheme, the shell is the external structure of the gas relay; the inclined plate is used to make the bottom surface of the cavity (i.e., the space for containing oil) inclined to ensure its unidirectional flow; the connecting port is the output end of the oil; the plug can close the connecting port when the device is not in operation; the middle partition can separate the cavity to avoid large fluctuations in the oil, and a strip-shaped gap is provided at the lower end of the middle partition to ensure that the two sides of the middle partition can be connected; the top surface is the upper end surface of the shell; the vent valve is used to discharge excess gas; the cylinder extends into the shell, and a number of diamond-shaped holes are opened on it for exporting gas; the sleeve is used to accommodate the terminal, thereby structurally protecting the terminal; the connecting pipe is used to connect the terminal with the inside of the shell; the flange cover is used to close the top of the sleeve; the bypass pipe is used to supply the line in and out of the sleeve, thereby connecting with the terminal; the camera is used to collect the liquid level image, and then send it to the background through a conventional wireless transmission module for remote monitoring by the staff; the front port is used to open the shell; the front cover is used to close the front port.
