Topic: Use and maintenance of the hinge of the cabinet door of the overcurrent-proof switchgear.
In the power system, high-voltage switchgear is an important part, which plays an extremely important role in the safe operation of the whole power grid. As one of the important components of switchgear, the quality of cupboard door hinge is directly related to the normal operation of equipment and the safety of staff. This paper will introduce the hinge of the cabinet door of the over-current prevention switch cabinet in detail.
I. Overview of hinge of cabinet door of overcurrent-proof switch cabinet
The so-called "over-current prevention" refers to a protective measure to automatically cut off the circuit when the electrical circuit is short-circuited or the current exceeds the specified value. Therefore, this factor should be fully considered when designing and selecting the hinge of the cabinet door of the over-current prevention switch cabinet.
First of all, from the material point of view: generally made of high-quality stainless steel material, with good corrosion resistance and mechanical strength; Secondly, we must ensure that it has high insulation performance to prevent electric shock accidents; In addition, it should have good bearing capacity and stability to meet the practical application requirements.
Second, the characteristics of the hinge of the anti-overcurrent switch cabinet door
1. Compact structure: this kind of products are usually made by integrated design, with beautiful and elegant appearance, small and light volume and easy installation, disassembly and replacement;
2. Easy to use: due to the special treatment process, the friction coefficient of this kind of products is small, so it is more labor-saving and convenient to operate;
3. Safe and reliable: In addition to the advantages mentioned above, this kind of products also specially strengthen the design of electrical isolation and protection part, thus ensuring that personnel and equipment are free from the risk of accidental injury.
III. Daily maintenance of the hinge of the cabinet door of the overcurrent-proof switch cabinet
Although these hinge products have been strictly tested and meet the requirements of relevant standards, we still need to pay attention to the following points:
(1) Regularly check whether the fasteners are loose, and timely adjust the tightening force to avoid potential failure;
(2) Clean up the surface stains and oil stains to keep clean and prolong the service life;
(3) Avoid deformation and damage caused by strong collision and vibration, which will affect the normal use effect.
In a word, we should pay enough attention to ensure the stable and efficient operation of the whole system, no matter from the production link or the later operation and maintenance management stage!
