Currently, the leading low-voltage switch products in China have functions such as trip circuit breakage monitoring, time detection for measures, detection of combat components, and energy storage time detection for springs, which together constitute intelligent low-voltage switches. "Song Zhichen, a researcher in the power industry at China Investment Corporation, said that with the continuous expansion of the industry's market and property scope, the growth rate of the industry has shown a downward trend. China's low-voltage switch industry should take the comprehensive support of a strong smart grid as an opportunity to strengthen self-reliance and innovation capabilities, and vigorously promote the level of intelligent switch equipment.
Low voltage switches continue to shift towards intelligence
"In the good situation of the growth of the low-voltage switch industry, manufacturers have increased the research and development of new low-voltage switches, attached importance to the promotion of product function and quality, tried to stop the horizontal expansion and vertical extension of property, and actively grow high-end products. In this process, intelligence will be an important growth bias." Yang Zhihua, deputy general manager of Siyuan Electric Co., Ltd. (hereinafter referred to as "Siyuan Electric") and general manager of domestic marketing center, said. In fact, low-voltage switches will combine functions such as control, signal, cover, measurement, and supervision, enabling low-voltage switchgear to have continuous self-monitoring and indirect connection with the power station control system, thus completing the arbitrary combination of multiple functions. This technology will lead the trend of low-voltage switch skill growth in the future. At present, well-known domestic brands' low-voltage switch products have the following functions, such as time-based detection, energy storage time-based detection of springs, temperature/humidity detection, and cabinet door supervision.
In the opinion of some experts, large backbone enterprises in the low-voltage switchgear industry should further deepen their research on the key skills and key components of ultra-low voltage switchgear, in order to achieve the goal of accommodating ultra-low voltage equipment domestically, independently researching and developing, and comprehensively completing localization. With the support of smart grids, digital substations, and distribution automation, we will vigorously promote the intelligence of low-voltage switches.
According to the "2013-2017 Analysis Report on Production and Sales Needs and Investment Forecast of China's Low Voltage Switchgear Manufacturing Industry" released by Forward looking Property Research Institute, during the 12th Five Year Plan period, China's low-voltage switchgear industry will take the comprehensive support of smart grids as an opportunity, rely on ultra-low voltage AC and DC transmission projects, continue to strengthen independent and innovative capabilities, increase the promotion of the intelligence level of low-voltage switchgear equipment, and promote environmental protection, energy conservation, and emission reduction equipment; Further enhance the overall skill level and domestic competitiveness of the low-voltage switchgear industry, and strive to complete the transformation of the low-voltage switchgear industry from large to strong.
The low-voltage switch market is a subsidiary of China's booming electricity market, and whether the electricity market grows in value indirectly affects the livelihood of the low-voltage switch market. In recent years, the globalization and high demand of the power transmission and distribution equipment market have mobilized the rapid growth of China's low-voltage switchgear market to a great extent. Yang Zhihua stopped elaborating on the rapid growth of low-voltage switchgear property in recent years. In the next few decades, with the strategic goal of combining the continuous growth of China's social economy with further promotion of scientific technology, the market prospects of low-voltage switchgear projects are attractive.
Today, the intelligence trend of low-voltage switches has significantly strengthened. To meet the needs of supporting the smart grid, the intelligence of power equipment has also received great attention from manufacturers and users. The continuous progress of device intelligence has led to the widespread application of contemporary sensing techniques, micro handling techniques, and condition monitoring and fault diagnosis techniques. Nowadays, the upgrading of electrical products is extremely frequent, often resulting in the elimination of many new product series in a short period of time. Along with the intelligentization of electrical components, low-voltage switches are also continuously shifting towards intelligentization.

Skill bottleneck becomes the crux of switch intelligent transformation
The rapid growth of industrialization and urbanization is driving the continuous growth of electricity demand, and the electrical equipment industry such as low-voltage switches is facing superior growth opportunities. However, the intelligence of China's switch industry still faces many challenges, and the technical bottleneck has undoubtedly become the crux of the intelligent transformation. Song Zhichen is concerned about the challenges faced by the intelligence of low-voltage switches, especially with the support of large-scale ultra-low voltage and ultra-low voltage transmission lines, the growth of smart grids, and the rapid promotion of power industrialization and urbanization. The low-voltage switch industry is facing more opportunities and challenges.
Some experts believe that benefiting from power support projects such as Hainet low voltage and smart grid, China's low voltage switchgear needs to have an expansion trend. However, compared with the prosperous market, the industry is facing a series of achievements such as product homogenization and excess production capacity. In recent years, with the increasing competition caused by excess production capacity and the continuous recovery of raw materials and labor costs, China's low-voltage switchgear industry has been walking on thin ice. The resulting price reduction and profit decline have brought the entire industry to a crossroads.
In fact, with the increasing competition caused by overcapacity and the continuous recovery of raw materials and labor costs, China's low-voltage switchgear industry is facing pressure from price reduction and profit decline. Under the new situation, the support of smart grids and ultra-low voltage has put forward new requirements for the intelligence of low-voltage switchgear. But with the deepening of market competition, product prices and profits are getting lower and lower, which leads to insufficient research and innovation talents in the future, making it difficult to achieve better growth. Some experts argue that the integration and reshuffle of the low-voltage switch industry have been pushed to the forefront of transformation, and the industry widely uses the phrase "waves washing sand" to describe the difficult situation faced by low-voltage switches today.
As a crucial component of power transmission and transformation projects, the high-end technology of low-voltage switchgear is controlled by foreign companies. In recent years, large backbone enterprises in the domestic low-voltage switchgear industry have continued to conduct seminars on the key skills and key components of ultra-low voltage switchgear equipment, making many efforts to achieve the goal of accommodating ultra-low voltage equipment domestically, independent research and development, and comprehensive localization. "Zhang Songlan, a senior property researcher and analyst at Forward Network, proposed an initiative for low-voltage switchgear enterprises.
It's surprising that it's not enough. The concepts of Zhang Xuanlan and Yang Zhihua are coincidentally the same. In the future market environment, if low-voltage switchgear companies want to achieve sustainable growth, they only need to tap into their potential internally. For low-voltage switchgear companies with significant livelihood pressures, the primary task is to ensure product quality and innovation without being eliminated, "Yang Zhihua told reporters. For those low-voltage switchgear companies that still have spare capacity, the most important consideration should be the next step, product diversification, high-end, or a good choice.
