Topic: Talking about the Importance of Door Hinge of Anti-trip Switch Cabinet
In power system, switch cabinet is one of the key components to ensure the normal operation of power equipment, and the door hinge of anti-trip switch cabinet is an important accessory of switch cabinet, and its performance and quality are directly related to the safety and convenience of switch cabinet.
First, the role of the hinge of the anti-trip switch cabinet door
1. Provide stable support: The main function of the door hinge of anti-trip switch cabinet is to connect the cabinet body with the door and provide stable support for the door. In the process of daily maintenance and overhaul of switchgear, hinges can ensure the cabinet door to open and close smoothly, and effectively prevent safety accidents caused by accidental fall-off of the cabinet door.
2. Ensure convenient operation: reasonable hinge design can improve the opening angle of the cupboard door, which is convenient for staff to carry out internal inspection or adjustment; At the same time, it can also reduce the impact on the surrounding environment when the switch cabinet is opened.
3. Enhance the sealing effect: High-quality hinges not only help to maintain the close fit between the cabinet door and the cabinet body, but also help other sealing parts (such as rubber strip) to better function, thus enhancing the overall protection level of the whole anti-trip switchgear and preventing dust from entering the working state of electrical components.
Second, the material selection and installation requirements of the hinge of the anti-trip switch cabinet door
1. In terms of material, it is suggested to use stainless steel to meet the requirements of strong corrosion resistance and durability; In addition, factors such as high temperature resistance should be considered to adapt to the use scenarios under different working conditions.
2. The installation position should be accurate and reliable, and the structural strength should be ensured while giving consideration to aesthetics. For example, in the initial stage of design, it is necessary to reasonably plan the size ratio of each part and reserve enough space for later maintenance.
3. Bolting is recommended as the fixing method, and the number of fixing points is increased by embedding steel plates to further improve the stability. At the same time, pay attention to control the tightening torque range of bolts to prevent damage to the surface treatment layer of parts.
Three, anti-trip switch cabinet door hinge common fault analysis and solutions.
1. The problem of unsmooth switch is mostly caused by loose deformation of parts caused by long-term wear. At this time, you can try to readjust the size of the installation gap or replace it with a new product.
2. Bad sealing is usually manifested as air leakage and water leakage. It is necessary to find out whether the reason is the aging failure of sealant and then take remedial measures, such as cleaning dust and debris regularly and applying special waterproof agent.
3. In some special cases, the hinge may break due to external factors (such as external impact).
Malfunction. At this time, it is necessary to thoroughly investigate hidden dangers and repair replacement parts in time.
To sum up, although seemingly inconspicuous, it is actually quite important that the door hinge of anti-trip switchgear plays a vital role in ensuring the safe operation of electrical facilities! Only by fully recognizing this point can we really do a good job in related management, and then promote the healthy development of the whole power industry!
