摘要
电梯的控制系统大量使用的场所容易受到外部和内部的电磁干扰。控制系统性能不稳定将会造成电梯的故障频发,大大降低电梯的舒适性和安全可靠性。电磁环境恶化给电梯运行环境带来的影响已不容忽视。对于已经选用或投入使用的电梯,其设计或选用的控制电路、控制方式、系统组成均已成型并进入使用过程。随着电磁环境进一步恶化、设备老化等因素,必须保证或改善电梯的电磁兼容性。
The place where the elevator control system is widely used is vulnerable to external and internal electromagnetic interference.The unstable performance of the control system will cause frequent failures of the elevator,which will greatly reduce the comfort and safety reliability of the elevator.The influence of electromagnetic environment deterioration on elevator operation environment can not be ignored.For the elevator that has been selected or put into use,the control circuit,control mode and system composition designed or selected have been formed and entered into the use process.With the further deterioration of the electromagnetic environment,equipment aging and other factors,the electromagnetic compatibility of the elevator must be guaranteed or improved.
