一、Introduction

Escalators are generally used in supermarkets, subways, stations, etc., and their applications are quite special. Unlike the elevators, no one was in a state of suspension. The escalator was in working state whatever someone or not, so it causes a waste of electric energy and accelerates the wear of the machine, and seriously affects the life of the escalator and lower safety.

V&T Inverter adopts high-performance speed sensorless vector control technology. According to the characteristics of the escalator, it develops the special integrated inverter energy-saving control cabinet for the escalator, adopts advanced detection methods and control algorithm to optimize the operation and achieve huge energy savings.

三、The advantages of using V&T inverter for transformation:

1. V&T Inverter adopts high-performance vector control, which makes the start-up smooth and shock-free, greatly reduce the impact on the power grid, improves the power factor, and makes people standing more comfortable and safer;

2. V&T frequency drive was used to carry out the transformation of the escalator. Speed regulation range was wide and the power saving was quite obvious. Advanced algorithms and detection methods have been adopted to greatly improve the operation of the motor and have considerable energy saving space;

3. Adopting frequency inverter transformation can greatly reduce the wear of the machine, reduce the degree of maintenance, and extend the service life of the escalator;

Adopt frequency inverter transformation, the inverter starting is smooth. the starting current was small, the impact of the motor was greatly reduced, and the service life of the motor was greatly upgraded;

5, High reliability, the inverter has perfect protection functions, such as over-current, overload and over-voltage etc;

6. If the feedback unit was selected, when the escalator was in the down state, the motor was in the power generation state, and the electric power can feedback to the power grid;

7. The frequency inverter system can coexist with the original system. V&T integrated energy-saving control cabinet also has the switching function of the industrial frequency conversion, which was convenient for online switching with the original system;

8. The operation panel of the inverter has the function of parameter copying, which greatly reduces the workload of maintenance and Commissioning;

9.Compared with the saved energy and mechanical wear and maintenance costs, the equipment transformation cost can recover the investment of energy-saving transformation in a short period of time, with significant economic benefits and social benefits, greatly enhancing the brand and value of users.
