Wind turbines work by converting the kinetic energy of the wind into mechanical energy through the turbine rotor blades. When the wind flows through the turbine blades, it causes the blades to rotate. This rotational motion drives a generator to produce electricity. Wind speed is measured by an anemometer , and is usually strongest at higher elevations with less disturbing obstacles.

Inverter is a power electronic device that adjusts the motor speed by changing the power supply frequency. According to the relationship between the motor speed and the power supply frequency, the inverter controls the motor speed by adjusting the output voltage and frequency.

Inverter mainly consists of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit microprocessor unit, etc. Through the internal IGBT disconnection, the inverter can adjust the voltage and frequency of the output power supply, and provide the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation.

High-voltage inverters are widely used in industrial scenarios such as metallurgy, electricity, and chemical industry, and are mainly used for variable frequency speed regulation of high-voltage AC motors. As the main core product in the field of industrial transmission, it is particularly important for high-voltage inverters to maintain a stable and reliable operating state.

High-voltage inverters are electrical equipment used in high-voltage power systems, which have the function of regulating voltage, frequency and power. Its main application areas include but are not limited to the following eight aspects.

We all know that the three-phase stator winding of the motor flows through the current to generate a rotating magnetic field. According to the principle of magnetic induction, the motor shell will generate an induced electromotive force. The magnitude of this electromotive force depends on the switching frequency of the frequency converter IGBT. Since high-performance control requires a high switching frequency, its switching speed is very fast, then DV/DT is too large, and at the same time, this induced electromotive force is too large, and people feel electric shock when they touch it.

High-voltage inverters are usually used in the industrial field and are suitable for high-power, high-voltage (usually over 1kV) applications. They can provide higher output power and carrying capacity, and are suitable for driving large motors, generator sets and other high-power equipment. The circuit design and control system of high-voltage inverters are usually more complex to cope with the requirements of high voltage and high current.

High-frequency transformer, also known as high-frequency converter, is a key electromagnetic component in the field of power electronics technology, mainly used for high-voltage, high-power power conversion occasions, especially in the switching power supply, inverters, frequency converters and other modern power electronic equipment occupies a central position.

As inverters are used more and more frequently in daily life, we need to know more about inverters, and using a multimeter to detect the good and bad inverters is a common method.

For the sake of the planet’s survival, we are increasingly promoting the use of renewable energy, and any source that can be supplemented and converted to supply electricity is a renewable energy source. There are various types of renewable energy sources including solar energy from the sun, tidal energy from waves, hydroelectric power from rivers and wind power, where turbines are used to harness the wind and convert it into electricity.

Due to the advantages of high speed regulation accuracy, advanced technology, rich functions, high reliability, simple operation, and strong versatility, the frequency converter is superior to any previous speed regulation methods, such as pole-changing speed regulation, voltage regulation speed regulation, slip speed regulation, cascade speed regulation, commutator motor speed regulation, hydraulic coupling speed regulation, etc.

According to statistics, nearly 60% of the wind power equipment on the global market is produced in China, and by the end of 2022, the cumulative installed capacity of global offshore wind power reached 57.6 GW, and the cumulative installed capacity of China reached 30.51 GW.

As far as electricity is concerned, there are two types: high voltage and low voltage. High voltage usually refers to a voltage that is higher than the standard or common voltage level, while low voltage, on the contrary, refers to a voltage that is lower than the standard or common voltage level.

A wind power converter is a power conversion device specifically designed to convert the direct current generated by a wind turbine (usually a wind turbine) into alternating current.

A water pump inverter is an inverter specifically designed to control and drive a water pump system. Its main function is to convert the output of a DC power source (e.g., solar panel, DC generator, etc.) into AC power and control the operation of an electric water pump with appropriate control algorithms.

The customer has two sets of 900KW and one set of 1250KW high-voltage inverter, due to the equipment is old, the operation of the frequent failure. Inverter internal power unit failure caused by equipment downtime maintenance time increases year by year, maintenance costs remain high.

A motor is a device that converts mechanical energy into electrical energy and vice versa. An electric motor is a motor that converts electrical energy into mechanical energy. These motors can run using either AC electrical energy or DC electrical energy.

In order to prevent the failure of the frequency converter, ensure the normal operation of the equipment and extend the service life of the frequency converter. It is necessary to carry out routine maintenance of the frequency converter, and the contents of routine maintenance are indicated as follows:

The customer needed a cabinet product consisting of 3 inverters and to achieve its purpose of use. So we recommend the NZ200, and more detials please click here.

Customers need to configure a high-voltage frequency converter for air-cooled screw machines, and ZONCN recommends ZCH100 as the high-end frequency converter. ZCH100 series high-voltage frequency converter adopts the form of multi-level “high-high” voltage source of power units in series.

Industrial water pumps, refers to water pumps used in industrial production. According to the customer’s demand, we recommend a part of low voltage inverter series, Z5000 series inverter for water pump.

Punching machine or stamping machine, die forging press, is a machine that uses pressure to deform metal and make it stamped into various required structures. The functions of a punch press include punching and shearing, metal material forming, deep drawing, and forging metal, which is generally used in conjunction with molds and dies, and is an important piece of equipment for the production of metal mechanical parts.

The principle of two-stage compression screw air compressor, the compression process is natural air through the air filter into the first stage of compression, in the compression chamber with a small amount of lubricating oil mixing, at the same time compressed mixed gas to the interstage pressure.
