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:

一、馬達漏電。受地上平坦度的影響，電機或許在波動的振動下長期運轉(zhuǎn)，增加了損壞電機部件的風險。此外，繞組的絕緣電阻會因潮濕而下降，電機會長期過載，有害氣體會被腐蝕，金屬異物會侵入電阻，導體的絕緣會被損壞和燒毀，然后導致漏電。

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.

二、電纜泄漏。因為線纜需要隨著門伸縮支架前后伸展，所以它不能被剛性地維護，而且它常常移動，增加了磨損程度。機械支撐對電纜有必定的機械損傷風險。一旦切斷絕緣維護層，...會造成漏電。此外，電纜將長期放置在室外。高溫、雨和霧會加快電纜護套的老化。

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.

在裝置和施工過程中，電纜應選用軟殼維護，軟殼應具有必定的強度，以應對機械損傷。漏電維護器應定期裝置和測驗。設(shè)置合理的行人開口寬度。根據(jù)上述情況，電動門預留人行通道的寬度少為0.9-1.2米，為通用人行出口的寬度值。地上應該做好標記，以便給操作者一個準確的提示。

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.

電動卷簾門的操作地上應平坦，無異物，以削減物理沖擊。為了削減漏電事端的產(chǎn)生和防備，咱們應從產(chǎn)品施工和裝置的源頭入手。施工過程中，廠家應特別注意產(chǎn)品的裝置：接地體應設(shè)置好，接地引下線不應選用單芯鋁線，裝置應由有資質(zhì)的...電工進行。

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.
