繼電器作為升降貨梯http://www.inductor-china.com/自動控制器件應用較廣泛，尤其是在涉及低壓電器控制網絡中有較多升降貨梯等環境中使用時電磁干擾問題更趨于嚴重。組成繼電器的內部元器件的損壞這時已不是引起繼電器故障（失效）的主要原因，而在于升降貨梯應用場合中的各種干擾通過電磁耦合、電容耦合直接進入繼電器，干擾其正常的延時控制。
Relay as cargo lifter wider application of automatic control devices, especially those with large cargo lifter electromagnetic interference and other issues involving the environment using low-voltage electrical control network tends to be more severe. Damage to the internal components of the composition of the relay time relay has not caused failure (fail) the main reason, but rather a variety of applications where interference cargo lift directly into the relay through electromagnetic coupling, capacitive coupling, interfere with the normal delay control .

繼電器在此干擾環境下能否正常工作往往會影響到升降貨梯http://www.inductor-china.com/整個自動控制系統的正常邏輯功能，甚至還可能造成升降貨梯大的質量事故和經濟損失。所以繼電器在各種惡劣環境都應有較高的可靠性和抗干擾能力，也就是說繼電器必須有良好的電磁兼容性能，只有這樣才能完善其產品質量，提高自身的市場競爭能力。
Relays can work properly in this interference environment tends to affect the entire cargo lifter normal automatic control system logic functions, and may even cause Huoti large mass accidents and economic loss. So relay in a variety of harsh environments should have high reliability and performance, which means that the relay must have good electromagnetic compatibility, the only way to improve the quality of their products and improve their competitiveness in the market.
