Energy-saving elevator rating
The assessment of energy-saving elevator registration can be similar to that of household appliances using five-level system, or AAA, AA, A, B, C five-level system. If the AC two-speed elevator is C-class, then the worm VVVF elevator can be Class B, and the permanent-magnet synchronous host power is smaller than the worm-worm main engine, so the VVVF elevator with permanent magnet synchronous host can be listed in the A-class. To get an AA-rated elevator, you must be able to save more energy than an elevator with a permanent magnet synchronous motor. The AAA-class elevator is the world’s most advanced elevator technology with advanced energy-saving technologies. According to the above situation and the actual use of the elevator, we propose the following hard index reference for energy-saving elevator rating AAA: permanent magnet synchronous host, VVVF control technology, elevator power generation utilization reaches 30-35%, does not directly impact the power grid. This type of elevator has good energy-saving effect and no impact on the power grid. It is a truly mature third-generation energy-saving elevator. AA: Permanent magnet synchronous host, VVVF control, can use elevator power generation, such as energy feedback, but energy feedback must comply with the national grid access conditions, with the technology of rectifying elevator electric energy and sine wave stabilization of electric energy without harmful to the power grid. Shock. The energy feedback utilization rate reaches 20-25%. This type of elevator enters the third generation energy-saving elevator line, but belongs to the third type of energy-saving elevator that enters the threshold. A: Permanent magnet synchronous host, VVVF control, this type of elevator has been widely applied for nearly ten years, and the sales volume is increasing year by year. The market proportion is increasing every year, the power consumption is saved, and the protection of the environment is better than the worm gear. The elevator is good, it is the mainstream product now, and will continue to increase its market share. This type of elevator is the second generation of energy-saving elevators. B: worm and worm main engine, VVVF control, this kind of elevator motor has relatively large power, but it is energy saving than AC two-speed, and it is also the first generation of energy-saving elevator technology, but it is gradually reducing production. There are still sales in the market, which was previously the mainstream product of the elevator. B-C: AC two-speed control, worm and worm elevator mainframe, PLC or older control mode, this type of elevator is mainly old elevators and cargo elevators.
