Electrical Instrument Market Analysis

At present, the domestic production capacity of electrical instrumentation products has reached more than 80 million units (sets). In middle and low-end products, such as traditional electric energy meters, installed electric meters, and portable electric meters, there is an excess production capacity, while in high-end products, such as high-accuracy digital meters, digital measuring instruments, automatic test systems, etc., and advanced countries. There is a gap in product technology, which cannot fully meet the needs of the domestic market and requires import.

Domestic market demand characteristics:

The market demand continues to increase, and the power sector is the market demand for the largest consumer electric instrumentation products. In recent years, the overall trend has continued to grow. Technological progress is the driving force for the development of electrical instrumentation. Over the past 20 years, especially during the 20 years of reform and opening up, electrical instrumentation products have made tremendous progress, and continuous progress has been made in product variety, quality and level. The electric power department is the largest user of electric instrumentation products. Its applied products cover all 13 categories of electrical instrumentation, and almost 100% of end users are electric energy meters, installed electric meters, and power transmitters. Power sector. The demand for electrical instrumentation products by the power sector accounts for about 90% of the market's demand for electrical instrumentation products, and it plays a decisive role in the demand for electrical instrumentation products. The remaining 10% of demand comes from other areas of national economic construction.

User's technical level requirements for major products:

The main features of the electrical instrumentation industry are the high density of technology, comprehensive development of various technologies, sensitivity to new technologies, and short product update cycles. As a result, the electrical instrumentation industry is faced with better opportunities and greater challenges. The new products of electrician instrument and meter emerge one after another, the user's requirement for the product level is higher and higher.

(1) Energy metering instrumentation and system: At present, the user demand is mainly based on the 86 series inductive energy meter, and the demand for the electronic energy meter (mainly single-phase) shows a rapid upward trend. During the 10th Five-Year Plan period, the inductive energy meter required by users will gradually transition to a 25- to 30-year-long life, with an overload capacity of 6 times or more; the demand for electronic energy meters will be further strengthened, and single-phase electronic energy meters and cards Pre-paid electronic energy meters, three-phase electronic multi-function meters and multi-rate electricity meters will be the main targets. High-precision watt-hour meter is mainly used at the gate or network port, but also has certain needs, but due to its high technical content, most of them are imported from abroad. Adopting a centralized automatic meter reading system to implement remote meter reading for all consumers is a development Trends, demand for automatic meter reading systems will also increase.

(2) Installed electric meters: Demands are mainly expressed in the structure and accuracy of products, and the standardization, serialization, and generalization of products are improved, and varieties and specifications are supplemented. This is an urgent task. The demand for converter-type instruments will gradually increase, and the demand for digitally-installed meters will also gradually increase.

(3) Laboratory and portable electricity meters: The demand for precision electricity meters will further shrink. Because digital meters are in absolute superiority in accuracy, cost performance, etc. compared to precision meters, the user's technical level of precision meter products is not Further increase the demand. The overall demand for portable electric meters will also be reduced. The requirements for this product are mainly concentrated on the appearance of the instrument, structural design, expanding the application field, and improving reliability.

(4) Digital instruments: The focus is on reliability. The high-precision meter (11/2 to 17/2 digits) must have an IEEE488 interface and be easily used in an automatic test system; a low-precision meter (7/2 to 9/2 digits) ) Key demand digital multimeters, digital clamp meters and digital panel meters, the technical level requirements are focused on reliability, improved appearance, and increased testing capabilities. If you can display the measured waveform of the multimeter, bar graph display digital panel table and so on.

(5) AC and DC electrical instruments: China's DC electrical instrument production level, quality, series, variety, specifications are relatively complete, the product has reached a certain level, and some are close to the world's advanced level to meet user needs. There is a certain gap between the exchange of electrical instruments and the advanced level of foreign countries, mainly because they are not uniform in variety, poor in complete sets, and the products do not form a series. In particular, there are few digitized instruments and they cannot fully meet the needs of users.

(6) Automatic test system: With the rapid development of science and technology, scientific experiments and production processes are all placing higher demands on the automatic measurement of electromagnetic measuring instruments. Some domestic units have been committed to the technical research and development of automated test systems, such as the development of computer-aided test systems CAT, standard interface bus systems IEEE488 and CAMAC, are currently developing and producing virtual instruments and VXI systems, but most of them stay in scientific research At the prototype level, industrial scale production has not been achieved. With the development of electronic technology, some large-scale scientific research projects, military and aerospace engineering tests also rely entirely on automated test systems to achieve, and therefore constantly put forward higher requirements for automatic test systems, from fully independent automatic test systems to more flexible Changing modular and modular automatic test systems are all objects of future demand.
