Inverter will become the battlefield of the future low-voltage electrical appliances

Recently, some experts pointed out that due to the current market application of high-end inverter is mainly occupied by the European, American, Japanese and Taiwanese brands, from the long-term development trend, so there are nearly 80% of the import substitution space, low-voltage electrical equipment will be the inverter The main battlefield for future sports.

Automation control is inseparable from the inverter. The medium- and low-voltage electrical appliances are the space for the development of the inverter. In the face of this feast of trillions of yuan, the inverter industry can deliver the geometry?

The starting current of the motor using the inverter starts from zero and gradually increases. The maximum value does not exceed the rated current, which reduces the impact on the power grid and the requirements on the power supply capacity, thereby achieving the effect of energy saving and extending the service life of the equipment. Equipment maintenance costs.

Especially in the field of fine processing, through the high-speed control of the motor speed by the inverter, the manufacturing process level can be greatly improved. It can be said that the inverter is currently the most ideal and most promising motor energy-saving equipment, and almost every industry in the national economy is inseparable from the inverter.

Although the frequency converter has many advantages, due to the price problem, its large-scale promotion and use is currently limited, and it is in a so-called embarrassing situation.

There are more than 300 frequency converter production plants in China, but their strength and scale are uneven. Individual companies still use workshop-style production models, and the main brands are maintained at 20-30.

The domestic inverter market is developed with the entry of foreign brands. The foreign brands are predominantly in the market, and currently occupy about 70% of the domestic inverter market.

The history of the establishment of most local companies is not long. Many products enter the market for a short period of time. It is still difficult to compete with internationally renowned brands in terms of product maturity and brand awareness. Local companies mainly produce V/F control products. For products with superior performance and high technological content, such as vector inverters, most companies in China have not yet developed mature products.

In addition, the personnel and funds of domestic-funded brands have been continuously separated and many companies have been established, mainly in coastal areas such as Guangdong, Zhejiang, Shandong, and Shanghai. With the intensification of market competition, many brands will be phased out. The future inverter market will be a market with higher brand concentration and more orderly competition.

For example, the operations of some inverter manufacturers are outsourced, such as outsourcing some inverter components. Due to improper management, there are potential quality risks.

With the rise of local brands, the market share of local inverter companies is gradually expanding, especially in recent years, the trend of accelerating the substitution of foreign brands.

At present, due to constraints in technology and capital strength, the development of local companies is still standing still. According to industry experts, the current growth rate of the installed capacity (power) of the upconverter in the Chinese market is actually around 20%. It is expected that the inverter market will be saturated and gradually mature after at least 10 years.

The market size of medium and low-voltage electrical equipment converters has increased at a level of 10% to 15%, but the growth rate in 2011 exceeded that of high-voltage converters for the first time, achieving an accelerated development of 30%. The market size is expected to be close to 20 billion yuan.

However, experts have warned that the low- and medium-voltage electrical equipment inverter industry is a strong cycle industry and is closely related to the national economic cycle. At the same time, although the driving factors of automation and upgrading of high-end equipment do not change, but under the strict national tightening policy last year, some SMEs due to raw material prices, labor costs and loan difficulties, the capital of new equipment procurement and technological transformation Sex investment is facing financial difficulties 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 channel developers for market development.
