Electric rolling shutter door is very common in life. Because the movement of the door body needs to be driven by electrical equipment, the failure of electrical equipment is inevitable, and leakage is one of them. Then, why does the electric telescopic door leak electricity? Let's follow the example of Fuqiang door industry:
1、 Motor leakage. Affected by the flatness of the ground, the motor may operate for a long time under fluctuating vibration, increasing the risk of damage to motor components. In addition, the insulation resistance of the winding will drop due to humidity, the motor will be overloaded for a long time, harmful gases will be corroded, metal foreign matters will invade the resistance, the insulation of the conductor will be damaged and burned, and then lead to leakage.
2、 Cable leakage. Because the cable needs to extend back and forth with the door telescopic support, it cannot be maintained rigidly, and it often moves, increasing the degree of wear. Mechanical support has a certain risk of mechanical damage to the cable. Once the insulation maintenance layer is cut off,... Will cause electric leakage. In addition, the cable will be placed outdoors for a long time. High temperature, rain and fog will accelerate the aging of cable sheath.
During the installation and construction, the cable shall be maintained with soft shell, which shall have certain strength to deal with mechanical damage. The leakage maintainer shall be installed and tested regularly. Set reasonable width of pedestrian opening. According to the above situation, the width of the pedestrian passage reserved for the electric door shall be at least 0.9-1.2m, which is the width value of the general pedestrian exit. The ground shall be marked to give the operator an accurate prompt.
The operation ground of electric rolling shutter door shall be flat and free of foreign matters to reduce physical impact. In order to reduce the generation and prevention of leakage accidents, we should start from the source of product construction and equipment. During construction, the manufacturer shall pay special attention to the device of the product: the grounding body shall be set well, the grounding down lead shall not use single core aluminum wire, and the device shall be carried out by a qualified electrician.
