Does anyone know how much an inverter generally costs?

The inverter is different according to the brand and model. Generally** is between 800-2000 yuan.

Variable-frequency drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The inverter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc. The inverter relies on the interruption of the internal IGBT to adjust the voltage and frequency of the output power supply, and provides 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.

With the continuous improvement of industrial automation, frequency converters have also been widely used.

300-600 yuan kilowatts, the greater the power, the cheaper, how much is the specific **, go to Aosheng inverter company to ask, many large domestic enterprises are purchased from them.

Frequency converters offer the following advantages:

High efficiency and energy saving: Tianke inverter adopts advanced PWM modulation technology and SVPWM control algorithm, so that the motor always runs in the high efficiency area, thereby greatly reducing the energy consumption of the motor and saving energy.

Flexible and diverse: Tianke inverter has a variety of control modes, which can meet the needs of different occasions, and supports a variety of communication protocols at the same time, which is convenient for integration with other equipment.

Easy maintenance: The maintenance and maintenance of Tianke inverter is very convenient, with good fault diagnosis and alarm function, which can find and eliminate faults in time.

As for the inverter, the inverter of different specifications and models is different, ranging from 300 yuan to 26,000 yuan. Of course, the actual ** may also be affected by some other factors, such as quantity, region, and so on.

The inverter is also different according to the different power**; There are also different brands, ** are also very different; According to the different power supply voltage, the ** of the inverter is also different; So you first have to determine what voltage, what power, and what brand of inverter you need to determine how much the price is. And there are many inverters of the same brand and model** that are different.

There are many types of inverters, such as large, small, simple, mini, and so on. Under normal circumstances, the inverter with small size and simple structure is more popular in the market, because it is small and convenient, fully functional and sells better, and the price is usually two or three hundred yuan. As for the smaller type, the process is more difficult than the simple type, and the price will be more expensive, usually selling for four or five hundred yuan.

If there are special working environment requirements, then you need a more complex product, and the price will increase accordingly.

Generally, it ranges from a few thousand yuan, but it still depends on the specific situation to judge how much it is.

2. How to choose inverter air conditioner.

1. When choosing an air conditioner, the number of horses is suitable for the area: suitable for 18-23, and there is a suitable P for P suitable for about 60, 10P suitable for about 100 For different brands on the market to claim to be "1 horse" air conditioner, we should look at its cooling capacity to make a measurement. The cooling capacity of 1 HP air conditioner is generally 2500W, and the cooling capacity of HP Air Conditioner should reach 3500W, and some such as 3000W should also be converted according to the proportion of its number of horses and applicable area.

2. When we are at home, how big is the inverter air conditioner to buyWhen we buy inverter air conditioners, we must be careful in many aspects, not only pay attention to how much of its large cooling capacity, but should choose the applicable area of the air conditioning products according to the actual use area of the room. The size of the air conditioner is determined by the number of horses, and different numbers of horses correspond to different applicable areas. The number of horses is bought small, and the number of horses is bought and the money is wasted.

After the implementation of the new energy consumption level policy, the energy efficiency limit value in the new energy efficiency standard has been increased by about 23%. Among them, the energy efficiency limit of split room air conditioners with rated cooling capacity less than or equal to 4500W is, the rated cooling capacity is greater than or equal to 4500W and less than or equal to 7100W, and the rated cooling capacity is less than or equal to 14000W.

3. The main slogan of inverter air conditioner is "power saving", "energy saving", "environmental protection" and "low carbon", which is directly related to the characteristics of the inverter air conditioner product itself. The so-called inverter air conditioner is based on the ordinary air conditioner, which selects a special compressor for inverter and adds a variable frequency control system. Its basic structure and refrigeration principle are exactly the same as those of ordinary air conditioners.

The main engine of the inverter air conditioner is automatically continuously changed, and it can automatically provide the required amount of cold (heat) according to the room situation; When the indoor temperature reaches the desired value, the air withering host can accurately maintain this, so as to ensure the stability of the ambient temperature.

How much is the inverter air conditioner and how to choose the inverter air conditioner, which is introduced to everyone, so as to ensure that our choice is more in line with our needs.

If a machine is working, the voltage provided by its motor to the machine is too large or too small, which will cause the machine to work abnormally, then it is necessary to change the voltage output of the motor through the inverter, which is adjusted according to the actual voltage required for the machine to work.

The continuous development of scientific research and technology has solved many problems that have been bothering us. For example, the problem of high voltage frequency, excessive power consumption of laundry, etc. Today I bring you a brief introduction to the high-voltage inverter and its introduction. Let's wait and see!

For those who are not familiar with the high-voltage inverter, it should be the first time to hear it. In fact, high-voltage inverters are used in a wide range of industries, such as large-scale petrochemical and municipal water supply.

The working principle of the high-voltage inverter is actually the process of converting the frequency by the on-off effect of the power semiconductor. There are 9 basic classifications of high-voltage inverters, namely current type and high-voltage type.

After we briefly understand the relevant introduction of high-voltage inverter, let's take a look at the high-voltage inverter.

The 5 most expensive models:

1. INVT high-voltage inverter GD5000 series, the current market price is 1000044 (999999) yuan;

2, Delixi high-voltage inverter CDL9200-P710T6, the current market price of 135505 (134759) yuan;

The above is the introduction of high-voltage inverters and 8 high-voltage inverters brought to you today. Because of its application in large-scale projects, the production requirements are very high, so it is also very expensive. Foreign countries generally buy their own domestic products, and China will also choose foreign products in important projects.

There is no leading brand in China, so we should take into account our own actual situation when purchasing, and consider it more comprehensively, after all, the high voltage inverter is still relatively high.

1.General-purpose inverters are actually not very expensive, the technical threshold is low, and the hardware configuration is not so high. As far as I know, the DSP of low-end inverters generally does not use TI, and Renesas or something.

2.High-end inverter, engineering inverter ** is still quite high, mainly reflected in the strong control performance, in the hardware configuration is higher than the general-purpose inverter.

3.Another reason is that the development of high-power power electronic equipment, the development of labor costs, equipment costs are not cheap, usually the development of high-end inverters, the company has to lose at least two or three years of money. In order to recover the cost, it is also necessary to sell it in terms of efficiency.

First, the gradual reduction method.

The so-called gradual reduction method is to reduce the scope of the fault step by step by analyzing the fault phenomenon and judging the measurement parameters, and finally implement it to the specific circuit or component generated by the fault. It is essentially a judgment process of affirmation, negation, reaffirmation, re-negation, and finally affirmation (judgment).

For example, after an inverter is powered on, it is found that there is no display on the operation panel. First of all, it is judged that there must be no DC power supply (the DC power supply voltage can be measured with a multimeter), and further inspection finds that the high-voltage indicator is on (the measured PN voltage is further confirmed), which denies the fault of the high-voltage circuit of the main circuit, and affirms that there is a problem with the power supply that supplies power to the operation panel in the switching power supply. If the AC voltage of the power supply is normal, there is no DC output, and there is no short circuit, it can be concluded that the rectifier tube of the power supply circuit is damaged.

This example uses a typical step-by-step scaling approach. The whole process is to judge, affirm, and deny several rounds through analysis and parameter measurement, and finally determine that the rectifier tube is damaged.

Second, the method of touching melons along the vine.

According to the working principle of the inverter, the so-called Shun Teng method is a method to follow the fault site, along the signal path, and gradually go deeper, directly to the fault point, and finally find the fault site.

For example, the output voltage of a frequency converter is unbalanced in three phases. This failure is apparently caused by 2 possibilities. One possibility is that at least 1 of the 6 units in the inverter bridge is damaged (open circuit), and the other possibility is that at least 1 of the 6 groups of drive signals is damaged.

Assuming that one inverter unit has no driving signal, the fault in the driving circuit can be further determined, and the method can be used to find it. In this example, you can look from the top down, that is, from the source of the drive signal, that is, the output of the CPU.

When there is a signal at the CPU output, check whether there is a signal at the input of the optocoupler, if there is no signal, the CPU will be disconnected from the input of the optocoupler. If there is a signal, check the optocoupler output to see if there is a signal at the optocoupler output. If there is no signal, the optocoupler is damaged.

If there is a signal at the input end and no signal at the output end, it indicates that the fault occurs in the amplifier circuit, or the amplifier tube or related components are damaged. Then it's easy to implement it further.
