Importance and Application Analysis of Hinge in Anti-sandstorm Power Equipment Box

I. Introduction

With the rapid development of economy and the acceleration of urbanization, all kinds of infrastructure construction are in full swing. Among these infrastructures, power facilities are one of the important links to ensure people's lives and promote social and economic development. As an important part of power facilities, power equipment box is the key to ensure the normal operation of power system. However, in some areas with serious desertification, power equipment boxes are often affected by sandstorms, which leads to the failure of normal use of power equipment. Therefore, it is particularly important to develop the hinge of anti-sandstorm power equipment box suitable for harsh environment.

Second, the design principle of the hinge of the sandstorm-proof power equipment box

The design of hinge for anti-sandstorm power equipment box mainly considers the following points: first, it is necessary to ensure the stability of hinge structure and keep it open or closed even in strong wind environment; Second, hinge materials are required to have good corrosion resistance and can adapt to the special climatic conditions in desert areas; Third, it is necessary to adopt special sealing technology to prevent sand from entering the hinge and affecting its work.Performance. In addition, the hinge surface needs special treatment to enhance the wear resistance, and reduce the weight by optimizing the design, so as to facilitate installation and maintenance.

Third, the application status of hinge for wind-blown sand-proof power equipment box

At present, there are two types of hinges commonly used in the market to prevent sandstorms: one is made of high-quality stainless steel; The other is a product made of aluminum alloy and processed by special technology. These two types of hinges have high strength and rigidity and excellent corrosion resistance, which can effectively resist sand erosion.

Fourth, case sharing

A power supply company installed a number of new hinges for preventing sandstorm in a substation on the edge of Taklimakan desert in Xinjiang. It was found that these hinges not only greatly improved the safety and stability of the equipment box door when it was opened and closed, but also effectively avoided the occurrence of short circuit caused by dust intrusion. According to statistics, before using this product, the number of failures caused by dust every year was as many as dozens of times; However, after the new hinge is adopted, the probability of such accidents is obviously reduced, which greatly reduces the maintenance cost.

V. Summary and prospect

To sum up, it is of great significance for improving the reliability of China's power grid system to develop the hinge of anti-sandstorm power equipment box for the demand of harsh natural environment. In the future, we can further explore more new materials and technical means to improve the performance of existing products, and extend them to a wider range of fields to make contributions to building a safer and more reliable modern energy system.
