Description

Technical Field

[0001] The utility model relates to the technical field of gas online monitoring, in particular to a gas online monitoring device. 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] Some gas online monitoring devices currently on the market: for example, the utility model patent with authorization announcement number CN214503824U discloses an online monitoring device for light gas, which is implemented by clamping a first clamp between two fixed plates, and then sleeved a second clamp on a screw rod, at which time the second clamp is also clamped between the two fixed plates, and the bracket is fixed to the fixed plate by rotating the nut. The camera on the bracket shoots the light gas liquid level in the observation window, which is then sent to the background server for processing and analysis by the controller through the wireless communication module. This setting can monitor the liquid level of the observation window in real time, but since the device lacks an observation window cleaning mechanism, the observation window cannot be cleaned. As an exposed component, the observation window is easily affected by impurities such as dust and dirt in the surrounding environment. Dust on the observation window will affect the observation of the camera.

[0004] Therefore, we propose a gas online monitoring device to solve the above problems. Utility Model Content
