Description

Technical Field

[0001] The utility model relates to the technical field of power equipment safety, in particular to a sulfur hexafluoride gas leakage alarm device in power equipment. Background Art

[0002] At present, sulfur hexafluoride gas (SF6) is widely used in power equipment as an excellent insulating medium and arc extinguishing medium in high-voltage switchgear, transformers and other equipment. However, sulfur hexafluoride gas has a very strong greenhouse effect, and its global warming potential is about 23,900 times that of carbon dioxide. Once a leak occurs, it will not only cause serious pollution to the environment, but may also cause safety accidents such as fire and explosion. Therefore, it is particularly important to monitor sulfur hexafluoride gas in real time and issue a timely alarm.

[0003] At present, although there are some sulfur hexafluoride gas leakage detection products on the market, most of them have problems such as low detection accuracy, slow response time, and inconvenience in use, which are difficult to meet the needs of actual applications. Moreover, when it is necessary to repair and inspect power equipment, the device may be damaged during the removal and reinstallation of the alarm device. Once a fault occurs, there will be a detection vacuum period and the alarm cannot be issued in time, which brings great hidden dangers to the safe operation of power equipment. Utility Model Content

[0004] The utility model aims to provide a sulfur hexafluoride gas leakage alarm device in electric power equipment, which solves the problems raised in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a sulfur hexafluoride gas leakage alarm device in power equipment, comprising:

[0006] Install the base;

[0007] A power supply assembly, the power supply assembly comprising a power supply seat mounted on the mounting base, and two power supply heads symmetrically mounted on the upper end of the power supply seat;

[0008] A fixing assembly, the fixing assembly comprising two groups of clamping strips symmetrically arranged on the mounting base and hand-tightened bolts installed on the clamping strips;

[0009] The detection component is clamped on the clamping strip, and two groups of the detection components are provided. The bottom of the detection component is connected to the power supply head of the power supply component.

[0010] Furthermore, the mounting base is provided with mounting holes, and there are four mounting holes, which are arranged at four corners of the mounting base.

[0011] Furthermore, the power supply head includes a receiving frame arranged on the power supply seat, a spring installed in the receiving frame, and a contact electrode arranged at a free end of the spring.

[0012] Furthermore, the detection component includes a detector housing connected to the card strip, an audible and visual alarm arranged at the lower part of the detector housing, a display controller arranged at the upper part of the detector housing, a gas detection head arranged on the detection housing, and a wireless module arranged on the side wall of the detector housing, and the display controller is electrically connected to the audible and visual alarm, the display controller, the gas detection head, and the wireless module, respectively.

[0013] Furthermore, a card slot corresponding to the card strip is provided on the rear side of the detector housing, an inverted funnel-shaped auxiliary slot is provided at the lower end of the card slot, and a plug-in interface connected to the contact electrode is provided at the bottom of the detector housing.

[0014] Furthermore, four of the clamping strips are provided, and the clamping strips are symmetrically arranged in a group of two, and the cross-sections of the clamping strips and the clamping slots are both in a convex-shaped structure.

[0015] Compared with the prior art, the utility model has the following beneficial effects: First, the configuration of two sets of detection components constitutes a double insurance mechanism. When one set of detection components fails or needs maintenance, the other set can continue to work, ensuring the continuity and reliability of gas leakage monitoring. This design significantly improves the stability and safety of the device, providing a strong guarantee for the safe operation of power equipment.

[0016] Secondly, the arrangement of two sets of detection components expands the monitoring range. They can be distributed in different locations of the power equipment, thus achieving comprehensive monitoring of the equipment's interior and surrounding areas. This layout helps to find potential leaks in a timely manner and enables accurate leak detection even in complex equipment environments.

[0017] In addition, the configuration of two sets of detection components also enhances the flexibility and scalability of the device. According to the specific needs of the power equipment and site conditions, the number, type and layout of the two sets of detection components can be flexibly configured. This flexibility and scalability enables the device to adapt to power equipment of different sizes and types and meet personalized monitoring needs.

[0018] Data redundancy and verification is another significant advantage. The redundant data provided by the two sets of detection components can verify each other, thereby improving the accuracy and reliability of the detection results. This data redundancy mechanism helps to eliminate false positives and false negatives and ensure the accuracy of alarm information.

[0019] Finally, the device has strong fault tolerance. In extreme cases, if one set of detection components is strongly disturbed or damaged, the other set can still work normally, providing operators with timely leakage warnings. This fault tolerance makes the device more adaptable and reliable in complex and changing environments. BRIEF DESCRIPTION OF THE DRAWINGS
