Design and Application of Side Hinge of Anti-overload Switchgear
As an important facility in power equipment, switchgear is widely used in various occasions to control, protect and distribute electric energy. In order to ensure its normal operation and improve its safety, the anti-overload design is particularly important.
1. Overview
With the continuous development of power system and technical progress, the reliability requirements of electrical equipment are getting higher and higher. Among them, switchgear, as an important part of the power grid system, plays an important role in ensuring the safety of power supply. Therefore, in order to ensure that the switchgear can work stably for a long time, it is necessary to carry out reasonable structural design to prevent overload, including the design of the side panel hinge of the switchgear.
2. Design concept
(1) Selection of suitable materials: In the design, priority should be given to the selection of materials with high strength and not easy to rust and corrode, and the required dimensions and specifications should be determined through scientific calculation;
(2) Use high-quality fasteners for connection and fixation, such as bolts and rivets, to ensure that the whole hinge mechanism has sufficient tensile capacity and rigidity;
(3) Enhance the pressure resistance: support ribs can be added on the original basis to enhance the stability of the overall structure, and at the same time, it can also play a role in distributing the load;
3. Application examples
A new type of anti-overload switch cabinet produced by a factory adopts the above design concept, and has been customized for different models of products. The details are as follows:
(1) Adjust the hinge length and quantity configuration scheme according to actual needs to realize flexible assembly;
(2) The spring buffer device is introduced to relieve the impact force and prolong the service life;
(3) Add auxiliary measures such as sealing ring or waterproof gasket to prevent short circuit failure caused by moisture intrusion.
4. Conclusion
To sum up, for the side hinge of overload-proof switchgear, its design idea mainly focuses on how to improve its mechanical performance index. Only in this way can we better meet the growing safety requirements and finally achieve more efficient and convenient production and operation goals.
