IPC Plus | Energy Conservation Promotion Week 2019 National Public Institutions Energy Conservation Promotion Campaign

● Green development, energy saving first

 

 

 

Energy Conservation Publicity Week 2019 National Public Institutions' Energy Conservation Publicity Campaign

The National Agency Affairs Administration and the Sichuan Provincial People's Government jointly organized the "Green Development and Energy Conservation First"-the 2019 Energy Conservation Publicity Week National Public Institutions Energy Conservation Publicity Campaign in Sichuan. The time is from June 17th to 23rd, and the theme is "Green Development, Energy Conservation First"

 

Leaders of the National Agency Affairs Administration, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development and other ministries and commissions, relevant comrades of 31 provinces (autonomous regions, municipalities) public institutions energy conservation management departments, and relevant responsible comrades of member units of the Sichuan Provincial Public Institution Energy Conservation Work Coordination Group, As well as some government agencies, institutions, schools, hospitals and volunteer representatives, a total of more than 1,000 people participated in the event.

 

Exhibition site

 
 

Our company is fortunate to participate in publicity activities together with Sichuan Jiekang Technology Co., Ltd. This time our company mainly displayed the new elevator energy-saving equipment-the ninth-generation PFE elevator feedback energy-saving device. The new product greatly improves the performance and safety on the original basis. Sex and stability.

 

Features of PFE elevator feedback energy-saving device:

 

1. Adopt high-speed DSP central processing unit

Upgrade a new generation of feedback control software, accurate control accuracy, good stability, less harmonics, and strong anti-interference ability.

2. Adopt the latest SVPWM modulation technology in the industry

Upgrade the new generation of SVPWM vector control technology to meet all the requirements of the national standard for elevator energy feedback on current harmonics.

3. Meet the national standard of elevator energy feedback device

Upgrade a new generation of control software and hardware, and pass the tests of GB/T 32271-2015 "Elevator Energy Feedback Device" and TSG T7007-2016 "Elevator Type Test Rules", report number: WT NET 18-410.

4. Standard RS485 communication and feedback power display

The product is equipped with standard RS485 communication and keyboard communication display, and all software control parameters are open for display and debugging, which is convenient for product monitoring.

5. Prevent islanding effect

The software monitors the status of the power grid in real time, and the power outage of the power grid will immediately stop the power feedback to the grid to prevent the islanding effect.

6. Using LC filter technology

Optimize the LC filter, effectively suppress harmonics and electromagnetic interference, voltage and current THD<5%, to ensure clean energy feedback.

7. Using automatic phase sequence identification technology

The automatic phase sequence identification technology is upgraded, and the phase sequence of the three-phase power grid can be connected at will, without the need to distinguish the phase sequence artificially.

8. Upgrade the hardware design to exceed the requirements of the national pressure withstand standards

The newly upgraded hardware design meets the withstand voltage of 2500V AC for 1min, and the leakage current is less than 2mA, which is far lower than the national standard 30mA requirement.

9. Highly integrated hardware design to improve product reliability

Except for the reactor, the hardware design circuit all adopts PCB integrated circuit design to improve the consistency and reliability of the product.

10. Improve the feedback current level of the machine

The newly upgraded hardware and control software reduce the volume of the product machine by more than 31%, and at the same time, increase the feedback current by 34%.

11. Standard air switch and fuse

Standard configuration of DC and three-phase AC fuses, standard configuration of air circuit breaker, short circuit protection in place, to ensure the safe operation of the elevator.

12. It can automatically escape from the fault to ensure the normal operation of the elevator

It is mutually redundant with the original control system of the elevator, and does not change the original control method of the elevator.

13. Adopt a variety of original technologies, compatible with all brands of elevator inverters

14. The energy-saving effect is remarkable, the comprehensive energy-saving rate reaches 20%~50%

15. Regenerative power feedback efficiency is as high as 97.9%

16. Simple installation, debugging, operation and convenient maintenance

Application

Application of PSG energy feedback device in mine hoist

Most of the coal mine hoists use a resistor in the stator coil of the motor to achieve the effect of speed regulation. During operation, part of the energy is released to the resistor by releasing electrical energy, thereby reducing the speed of the motor, which is bound to cause some electrical energy. Loss and waste. In addition, the resistance heating increases the indoor temperature. As the motor runs for a long time, the motor shell becomes severely heated and needs to be shut down for cooling, which greatly reduces the life of the motor and also affects the production efficiency. The society is progressing and technology is developing. This confusion has aroused the attention of equipment users. The installation of energy feedback has been widely used. Of course, energy feedback should replace the backward control method of resistance heating.

Application of PSG feedback unit on dynamometer

The dynamometer is also called the motor type test system in the motor testing industry, which mainly tests the load characteristics of the motor. The dynamometer is a load machine that applies a variable torque load to the motor under test and absorbs its power. Equipped with a display control system, it can test various types of motors (such as: single three-phase asynchronous motors, synchronous motors, DC motors, series The input voltage, current, power and output torque, speed, power and characteristic curve of excitation motor, power tool, wheel hub motor, starter motor, automobile motor, etc.). According to the working principle, it is mainly divided into hysteresis dynamometer, magnetic particle dynamometer, electric turbine dynamometer, and electric dynamometer.
