变频回馈节能技术在电梯中的应用

Application of Variable Frequency Feedback Energy Saving Technology in the Elevator

高层建筑正在增多,电梯也耗费了更多的总能耗。在减速运行中,电动机再生发电,很难快速起动或者调速。电网若未能接受反馈回来的再生电能,功率将被耗费,浪费较多的电梯能源。在这种状态下,电梯节能应受到注重。相比于常规技术,变频回馈新式技术可节省更多能耗,拓展了节能空间。借助变频回馈,机械能变为电能后送入电网。这有利于节省运转中的电梯能耗,改善环境且节省电阻。

High-rise buildings are increased, the elevator also took more total energy consumption. In the slow running,motor renewable power generation, it is difficult to rapid start or speed. Grid if fail to accept feedback renewable electricity, power will be cost, waste more energy lift In this state, the elevator energy conservation should be able to pay more attention. Compared with the conventional technology, variable frequency feedback new technology can save more energy consumption and expand the energy saving space. With the aid of frequency conversion, the mechanical energy can be changed into electrical energy and then sent to the power grid. This is conducive to saving energy consumption in the operation of the elevator, improving the environment and saving resistance.
