Introduction of the working principle of elevator appliance

Today, the elevator has been a necessary tool in our daily life, but it still consumes a certain amount of energy. In order to reduce the energy consumed by the elevator work, the elevator electric appliances appeared. So how does it work to save electricity? This paper introduces the working principle and characteristics of one of the elevator appliances.

The elevator electric power feedback device mainly adopts DSP processor technology, PWM pulse modulation and bi-directional voltage tracking technology, will be produced in the elevator braking energy back to the grid and used again in order to achieve the goal of energy saving. The energy saving effect of the energy saver is high, the electricity saving rate can reach thirty percent to fifty point five six percent, and the energy conversion rate can reach over ninety-seven percent.
.
This kind of energy saving device with DSP CPU, so has the characteristics of high speed, high precision, good stability and low harmonic strong anti-interference capability, convenient installation and convenient, the whole system is only six lines, will not change the original elevator control, the use of the original elevator and parallel resistance, this structure is more reliable. At the same time, the energy saving device adopts self diagnosis technology and two-way automatic voltage tracking mode to ensure the accuracy of output voltage and prevent the current return in the elevator, so that the elevator's work is not affected by any negative effects.
