Description

Technical Field

[0001] The invention relates to the technical field of instruments and meters, and in particular to a housing component for protecting a visual identification sulfur hexafluoride density meter. Background Art

[0002] Sulfur hexafluoride circuit breaker is a kind of circuit breaker that uses sulfur hexafluoride gas as arc extinguishing medium and insulating medium. The sulfur hexafluoride gas is sealed in a container with constant volume. At the rated pressure at 20°C, it has a certain density value. Within the various allowable conditions of circuit breaker operation, although the pressure of sulfur hexafluoride gas changes with the change of temperature, the density value of sulfur hexafluoride gas remains unchanged. Since the insulation and arc extinguishing performance of sulfur hexafluoride circuit breaker depends to a large extent on the purity and density of sulfur hexafluoride gas, it is particularly important to detect the purity and density of sulfur hexafluoride gas. If only an ordinary pressure gauge is used to monitor the leakage of sulfur hexafluoride, it will be impossible to distinguish whether there is a real leakage or the pressure change of sulfur hexafluoride gas is caused by the change of ambient temperature. Therefore, a special sulfur hexafluoride density meter needs to be installed for monitoring.

[0003] The sulfur hexafluoride density meter can display the sulfur hexafluoride density value in real time through the pointer and scale, but it is protruding from the surface of the equipment, which is prone to accidental contact. The sulfur hexafluoride density meter itself has high precision and high requirements for air tightness. Therefore, the above-mentioned accidental contact phenomenon can easily cause damage to the instrument. In addition, the current conventional sulfur hexafluoride density meter only feedbacks the density value through the indication of its needle. If you want to monitor the density value regularly, you need to check it frequently at the instrument. To address this problem, some researchers use a camera direct shooting mode to obtain the instrument panel image and remotely transmit it to the computer for remote viewing by managers. This type of structure is a visual identification sulfur hexafluoride density meter. However, adding a camera to the sulfur hexafluoride density meter that already protrudes from the equipment will make the protruding structure more complicated and scattered, which is not only more likely to cause accidental contact, but also lacks an effective protection structure for the instrument and camera. Summary of the invention

[0004] The present invention aims to address the technical defects of the prior art and provide a housing component for visually identifying the protection of a sulfur hexafluoride density meter, so as to solve the technical problem in the prior art that conventional sulfur hexafluoride density meters lack a protective structure.
