Design and Application of Hinge of Strong Explosion-proof Switchgear

I. Introduction

In power system, switchgearAs one of the important electrical equipment, it bears the important responsibility of opening and closing the circuit in the daily operation process, and the hinge of explosion-proof switchgear plays a vital role. Strong hinge of explosion-proof switchgear is the key component to ensure the normal operation of explosion-proof switchgear, and its performance directly affects the safe and stable operation of the whole power system.

Second, the characteristics and structure of solid explosion-proof switchgear hinge

1. Material: The hinge of a sturdy explosion-proof switch cabinet is generally made of high-strength alloy material, which has good corrosion resistance and impact resistance.

2. Structural design: The hinge of the sturdy explosion-proof switch cabinet adopts a unique sealing design and a special cushioning device, which can effectively prevent explosive gas or dust from entering the switch cabinet and causing fire accidents, and at the same time avoid the impact of external harsh environment on the switch cabinet.

3. Installation method: The hinge of the sturdy explosion-proof switch cabinet is usually installed by bolt, which is convenient, fast, stable and reliable.

Third, the application field of solid explosion-proof switchgear hinge

Solid explosion-proof switchgear hinges are widely used in flammable and explosive environments such as underground coal mines and chemical plants, such as mine flameproof high-voltage vacuum power distribution devices and mine flameproof and intrinsically safe low-voltage feed switches, which provide security for these special occasions. In addition, it is also widely used in various explosion-proof electrical products in the petrochemical industry.

Four, maintenance matters needing attention

In order to ensure that the hinge of solid explosion-proof switchgear is in good working condition for a long time, it needs to be inspected and maintained regularly:

1. Clean the surface dust and dirt;

2. Check whether the fasteners are loose and tighten them in time;

3. Add proper amount of lubricating oil to the moving parts to keep the lubrication effect;

4. Regularly check whether the insulation resistance value meets the requirements.

V. Conclusion

To sum up, the hinge of solid explosion-proof switchgear, as a key safety protection facility, plays an irreplaceable role in ensuring the safety of people's lives and property. Therefore, relevant enterprises and individuals should fully realize its importance and strengthen the quality supervision of this product; At the same time, it is also necessary to improve users' cognitive level of correct operation methods and jointly promote the healthy development of China's power industry.
