Design and Application of Door Hinge for Surge-proof Metering Box
With the rapid development of modern power system, metering box, as one of the infrastructure of power grid, is gradually known and valued by people. Among many electrical equipments, the anti-surge metering box is welcomed by people because of its good protective performance, and the door hinge is an important part in its design.
1. What is an anti-surge metering box?
Anti-surge metering box is a device used to protect power system from overvoltage caused by lightning or operation, which is usually installed outside buildings or underground cable wells. It has waterproof and anti-corrosion functions, and can effectively avoid potential safety problems caused by external environmental factors.
2. The importance of door hinges
Door hinge is the key component connecting the door panel and the box body of surge-proof metering box, and it plays the role of opening and closing the door during use. A good door hinge should not only ensure the flexibility of the switch, but also have high bearing capacity and stability.
3. How to choose the right door hinge?
For surge-proof metering box, it is very important to choose which type of door hinge. Generally speaking, consider from the following aspects:
Material: due to the influence of various corrosive gases and moisture in the working environment, it is best to make it of stainless steel;
Structural form: choose single door or double door according to actual needs;
Size specification: after determining the required size, the required quantity and installation location can be accurately determined;
Safety performance: Considering the safety problem, we should also pay attention to whether there is a locking mechanism or not.
4, installation considerations
During the installation process, you should also pay attention to the following points:
Cleaning the surface: clean the place to be installed to prevent foreign objects from affecting normal use;
Accurate measurement: according to the requirements of design drawings, accurately measure the spacing and levelness deviation of each part;
Follow the steps: complete all the links and tasks one by one in the order provided in the manual.
5. Maintenance
In order to ensure the long-term and stable operation effect, it is necessary to check and maintain the door hinge regularly:
Routine inspection: the whole device should be thoroughly investigated every once in a while and abnormal conditions should be handled in time;
Replacement of parts: once the parts that are seriously damaged are found, they must be replaced immediately to avoid more serious consequences;
Oil lubrication: add proper amount of grease in time to reduce wear and prolong service life.
In a word, when choosing the anti-surge metering box, we should not only pay attention to the overall quality and cost performance, but also pay attention to all the details (such as the "door hinge" introduced in this paper), so as to ensure the best performance of the product in the ideal state!
