     High voltage inverter start-up current smalldust fan energy-saving speed good choice

     TH-HVF  high-voltage inverter speed control cabinet is an energy-saving speed control equipment produced by Xiangyang Tenghui Electric for many years. It has good application response in various fans of environmental protection industry, especially in dust removal fans. Xiangyang Tenghui Electric Manufacturing Co., Ltd. is committed to the development of high voltage frequency conversion technology. Aiming at the main domestic energy consumption industries and high voltage speed regulation fields, the high voltage frequency converters produced by the company use the current international leading technology. The types belong to the high-high principle. Advanced power electronic devices are adopted. Many scientific and technological achievements in the field of modern power electronics and automatic control are integrated. IGBT modules adopt plug-in structure, which is convenient for exchange and replacement of the same unit. The high reliability is good, the efficiency is high, and the power saving effect is obvious. It is a very good choice for energy-saving and speed regulation of dust removal fans in the environmental protection industry.
     Dust  removal fan with high voltage frequency converter speed regulation after energy saving does not need to be equipped with additional compensation cabinet, also do not need to be equipped with step-down soft start equipment, but soft start cabinet can be used as a backup plan for high voltage frequency conversion, in emergency conditions can ensure normal production.
     TH-HVF is a high-performance high-voltage motor drive control device with unit series multi-level voltage source type. It has the characteristics of good voltage waveform and high control accuracy. It has the characteristics of miniaturization and small occupation space. It is not only suitable for dust removal fans, but also for other types of fans, such as axial flow fans, induced draft fans, exhaust fans, circulating fans and other three-phase asynchronous and synchronous high-voltage motors. It is also widely used in the energy saving requirements of electric power, building materials, metallurgy, mining, petrochemical, municipal and other industries. It is an updated product of large-scale motor drive control.
     
     
     
     
     
    Why do fans need speed regulation to save energy?
     
    In industrial production, electricity is the main secondary energy in modern society, and occupies an important position in people's daily life and industrial production.
    First of all, the fan used in daily production needs to be adjusted according to the air volume. The traditional method is to control the fan through the damper. The actual electricity consumption of the motor has not been reduced. This is the waste of energy. Frequency conversion can solve this problem very well. In large steel mills, environmental protection and dust removal requirements and other application fields, this measure can save considerable electricity consumption for enterprises in one year.

    High voltage frequency conversion can solve the fan speed regulation and energy saving needs well, so high voltage frequency conversion is widely used in the market.
     
     
    TH-HVFhigh-voltage inverterrelative to other speedadvantagesare as follows:
     
    1, high-voltage inverter speed range of 0~100, if the motor and load mechanical strength allows, the motor also does not flow, the inverter can also make the mechanical overspeed operation; and the hydraulic coupler speed range is generally 40~95, that is, the high speed section causes about 5 speed loss, affecting the output of the unit; and the hydraulic coupler is generally only 40 to the rated speed, in some cases, can not meet the speed regulation needs, and sometimes affect the further development of energy-saving benefits.
     
    2, high-voltage inverter in the entire speed range have higher efficiency (greater than 96); and hydraulic coupler in the lower speed when the efficiency is lower, itself brings a lot of loss, speed saving effect greatly reduced.
     
    3, high voltage inverter motor and load machinery to achieve a real soft start, completely solve the problem of high current impact in the starting process, if the process needs, the motor can be repeatedly started in a short time; and hydraulic coupler can not solve the motor start problem, the motor is still a direct start, need to start the device, start the impact is also large, and can not be frequently started.
     
    4, with high-voltage inverter motor speed transformation, just disconnect the original switch and motor connection cable, join the inverter can, do not move the motor and mechanical connection relationship, do not change any foundation, there is no site limitation problem; and with hydraulic coupler speed transformation, hydraulic coupler must be strung into the motor and mechanical connection shaft, need to move and re-casting equipment foundation, some places space may not be allowed.
     
    5, with high-voltage inverter speed control transformation of the motor, once the inverter failure, the motor can also be directly switched to the power frequency grid operation, will not cause production losses; and hydraulic coupling for the motor and mechanical connection link, once the hydraulic coupling failure, load machinery will not be able to operate, only shutdown maintenance hydraulic coupling, resulting in production losses.
     
    6, high-voltage inverter is high-tech equipment, high reliability, basic maintenance-free; and hydraulic coupler is mechanical equipment, itself contains oil, water and other sets of systems, high failure rate, maintenance workload, resulting in effective production time shortened. The hydraulic coupler itself also requires special maintenance.
     
     
     
    The main components ofTH-HVFseries high-voltage variable frequency speed cabinetare:
        Switchover cabinet/wiring cabinet: select according to requirements. Switchover cabinetwillswitch the motor to power frequency grid in case of system failure, andperform bypass function. Wiring cabinet will be connected to input and output lines of frequency converter without power frequency switching function. The customer can decide whether to equip the bypass switching cabinet according to the site requirements.
        Transformer cabinet:equipped with phase-shiftingrectifiertransformertoprovide AC input voltage for each power unit.
     Powercabinet: equipped with modular design of a number of power units cascadedinverter main circuit, toprovide the motor with variable frequency speed after the output voltage.
     Control cabinet: equipped with main control components, control the operation of frequency conversion speed regulation system and process the data obtained through collection,with variousdatacommunicationandDCScontrol interfacefunctions.

    The figure below shows the plug-in type of high-voltage variable frequency power unit module, which is convenient for maintenance. Equivalent units can be exchanged.
