EC300四象限电梯智能整体机的应用

EC300 four quadrant elevator intelligent applications of whole machine

本文以某电梯厂家试验塔内测试电梯为背景,描述了一款专为高速电梯应用市场而设计的高性能电梯智能整体机。普通的电梯智能整体机/变频器通常都是以能耗制动,通过制动电阻来释放电梯运行中产生的回馈能量,以热能的形式散发出去,如果温度过高还有可能烧毁制动电阻,威胁电梯的运行安全。在高速运行当中同时也会消耗大量的电能,并会出现电梯平层精度不高,舒适感差等问题,而使用EC300电梯智能整体机控制系统,不仅可以将电梯运行中产生的能量反馈给电网,提高能源的利用率,节约运营成本,同时也能提高客户的舒适感,保障电梯的运行安全。

Based on a certain elevator manufacturers test elevator test tower as the background, describes a specially designed for high speed elevator application market of high performance elevator intelligent machine as a whole. Ordinary elevator intelligent integral machine/frequency converter are usually based on energy consumption braking, through the braking resistor to release the feedback energy produced in the operation of the elevator, distributed in the form of heat, if the temperature is too high and may be burned braking resistance, threatening the elevator safety operation. In high speed running at the same time also will consume large amounts of electric energy, and there will be a flat floor elevator accuracy is not high, the issue such as difference of comfort, elevators EC300 and intelligent integral machine control system, not only can be produced in the operation of the elevator energy feedback to power grid, improve the utilization rate of energy and save operating costs, but also can improve the comfort of the customer, ensure the safe operation of the elevator.
