继电器作为升降货梯http://www.sdsjpt.net/自动控制器件应用较广泛,尤其是在涉及低压电器控制网络中有较多升降货梯等环境中使用时电磁干扰问题更趋于严重。组成继电器的内部元器件的损坏这时已不是引起继电器故障(失效)的主要原因,而在于升降货梯应用场合中的各种干扰通过电磁耦合、电容耦合直接进入继电器,干扰其正常的延时控制。
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 .

继电器在此干扰环境下能否正常工作往往会影响到升降货梯http://www.sdsjpt.net/整个自动控制系统的正常逻辑功能,甚至还可能造成升降货梯大的质量事故和经济损失。所以继电器在各种恶劣环境都应有较高的可靠性和抗干扰能力,也就是说继电器必须有良好的电磁兼容性能,只有这样才能完善其产品质量,提高自身的市场竞争能力。
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.
