Design and Application of Door Hinge of Anti-condensation Electrical Switch Cabinet
In the industrial field, the normal operation of power equipment is very important for the whole production process. However, in humid environment, especially in places where the temperature difference changes greatly, condensation is easy to occur in electrical switchgear, which will not only affect the working state of electrical components, but also may lead to safety accidents. Therefore, it is particularly important to design and use an electrical switch cabinet door hinge that can effectively prevent condensation.
I. Background introduction
With the development and progress of science and technology, more and more enterprises begin to pay attention to the safety and stability of power system to ensure the continuity of production. As one of the important parts of power system, electrical switchgear plays an important role. However, in some special environments, such as coastal areas or underground spaces, due to high air humidity and frequent temperature fluctuations, it is easy to form water droplets or fog inside the electrical switchgear, which is called "condensation". These moisture will adhere to the circuit board and metal parts, leading to short circuit failure and even fire accidents.
Second, the design ideas
In order to solve the above problems, this paper will propose a new one specially designed for the demand of condensation prevention.Hinge scheme of cabinet door of electric switch cabinet.
1. Material selection: the product is made of materials with good corrosion resistance and waterproof and breathable functions;
2. Structural optimization: by upgrading the traditional hinge, increasing ventilation channels and combining with sealing strips to achieve good internal and external air pressure balance;
3. Intelligent control: microcomputer chip technology is introduced to monitor the change of environmental parameters in real time, and the ventilation volume is automatically adjusted according to the needs, so as to avoid the harm caused by excessive moisture entering the cabinet.
Third, the specific implementation plan:
1. Detachable mesh filters are installed on both sides of the hinge to prevent external dust particles from entering the cabinet, and at the same time ensure sufficient ventilation area for smooth air circulation;
2. According to the actual needs of different application scenarios, set appropriate opening and closing angle limiting mechanism to prevent excessive opening and heat loss;
3. Using the principle of magnetic induction to detect the closed state of the cupboard door, and when it is not completely closed, it sends a warning signal to remind the operator to adjust the position relationship in time to enhance the tightness of the whole structure; 4. cooperate with the built-in dehumidification device to reduce the relative humidity on the surface and inside of the cabinet, prolong the service life and improve the work efficiency.
IV. Conclusion
To sum up, the door hinge of this anti-condensation electrical switch cabinet has the following advantages:
(1) Minimize the probability of potential safety hazards caused by harsh external conditions by combining multiple protective measures;
(2) It has the ability of intelligent management and can make flexible response decisions according to the actual situation on site, which further improves the reliability of the whole system;
(3) The installation is simple and quick, and the assembly process can be completed without additional auxiliary tools, thus saving costs and shortening the construction period.
In the future development, we expect more similar innovations to come out, and push related industries towards a more efficient and environmentally friendly direction!
