What are the benefits of installing economizer in industrial enterprises?
Frequency converter is a device that regulates the speed of an electric motor by adjusting the output frequency:1. The frequency converter can only reduce the motor speed by reducing the power supply frequency. The application environment is limited and the automatic control function is not available. It can not be used in many load changing occasions;Have a lot of 2 odd harmonics, frequency converter operation, it will seriously affect other equipment life and efficiency, at the same time use but also affect other precision control of the equipment in the factory, such as computer, automatic control system, monitoring system and so on;3 、 frequency converter serial access to the customer's low-voltage power system, the power supply of the customer security risks.
According to the frequency above 3 disadvantages, we developed and produced for Saver series under different conditions, based on frequency conversion technology, according to the field of electricity, increase control cabinet, electric / power conversion system, load detection and control system, input and output filter, DC reactor device etc.. The economizer has 4 advantages over the inverter:
1, through the intelligent online detection control system, closed-loop control can be completed, to keep track of changes in the load, load, change the machine output parameters, meet the requirements of the production process for customers, when customers need full load motor, motor output is not enough.For example: a plant water pump, motor speed can be supplied to a 100 force, the force is now 80, with the inverter directly to the 20 removed, and if the production process of the customer needs to provide 100 force, there will be a lack of motivation, affect the customer's production process and product quality. Such as the installation of our power class Saver, will not be the case, it can change the parameters at any time according to the requirements of the load, to ensure the normal supply of power.
The input and output filter and the DC reactor in the economizer can prevent the harmonic produced by the converter and cause the pollution of the power grid and the surrounding electricity environment.3 、 no disturbance power supply / electricity saving conversion system is beneficial to ensure that the customer load can be put into use quickly when the machine fails, and the normal production of the customer will not be affected. At the same time, the protection function of the economizer is perfect, and it has the protection function of over voltage, under voltage, over current, over temperature and surge resistance.4, reactive power compensation, improve the power factor of the system, reduce reactive power loss.
