Invitro Drive supplier believes that variable frequency energy saving will become the future trend

Invitrogen inverter manufacturers believe that inverter energy saving will become the future trend

       Automatic control is inseparable from the inverter, medium and low-voltage electrical appliances are the space for the expansion of the inverter; in the face of this feast of trillions of yuan, the inverter professional can be divided into several?

The starting current of the motor using the inverter starts from zero and gradually increases. The large value of zui does not exceed the rated current, which reduces the impact on the power grid and the requirements on the power supply capacity, thus achieving the effect of energy saving. It extends the service life of the equipment and saves the maintenance cost of the equipment.

Especially in the field of precision machining, the high-speed control of the motor speed by the inverter can greatly improve the manufacturing process. It can be said that the inverter is now the motor energy-saving equipment of Zui ambition and Zui, and the various industries of the national economy are inseparable from the inverter.

Although the frequency converter has many advantages, due to the price problem, its large-scale promotion and use is now constrained, and it is in the embarrassing situation of so-called screaming.

There are more than 300 inverter manufacturers in China, but the strength and scale are mixed. Individual enterprises are still selected to be used as a form of production. The number of primary brands is maintained at 20 to 30.

Domestic inverter shopping malls are carried out with the entry of foreign brands. Foreign brands are pre-emptive, and now they have a market share of about 70% in domestic inverter stores.

Most of the hometown companies have a long history of establishment. Many products have entered the mall for a short period of time. It is difficult to compete with internationally renowned brands in terms of product maturity and brand awareness. The local enterprises mainly produce V/F control products. For products with superior performance and high technical content, most domestic enterprises have not developed mature products.

In addition, the personnel and funds of domestic brands continue to separate, and many enterprises have been set up, mainly in coastal areas such as Guangdong, Zhejiang, Shandong and Shanghai. With the intensification of competition in the shopping malls, many brands will be gradually screened out, and the future inverter shopping mall will be a shopping mall with higher brand collection and more orderly competition.

For example, the operation of some inverter manufacturers is outsourced, such as outsourcing some inverter components. Due to improper management, there is a potential quality hazard.

With the enthusiasm of the hometown brand, the share of local inverter companies is gradually expanding, especially in recent years, the trend of accelerating the replacement of foreign brands.

Now, due to limitations in technology and capital strength, the development of the local enterprises has been in place. At present, the growth rate of installed capacity (power) of inverters in China's shopping malls is around 20%. It is expected that at least 10 years later, inverter stores will be saturated and mature.

The scale of shopping malls for medium and low voltage electrical equipment inverters has increased by 10% to 15%, but the growth rate in 2011 surpassed the high-voltage inverters, reaching 30% of the accelerated development. Nearly 20 billion yuan.

However, experts suggest that the medium and low voltage electrical equipment inverter occupation is a strong cycle occupation, closely related to China's economic cycle. At the same time, although the driving factors of automation and equipment promotion have not changed, but under the strict austerity policy of China last year, some SMEs have capital on new equipment procurement and technological transformation due to raw material price increase, labor cost addition and financial difficulties. The investment is facing a dilemma of funds, and the demand for frequency converters has slowed down. The use of acceptance bills by small and medium-sized users has also reduced the enthusiasm of the channel operators.
