General Circuit Breaker
Analysis Of The Gap Between Domestic And International Air Circuit Breaker
Over the past decade, China's air circuit breaker has been great development in the manufacturing sector, the product quantity, grade, quality, basically to meet the domestic demand for low-voltage power grid, its main products are universal type and Molded Case two broad categories. At present, China's production of universal-type air circuit breaker has DW15, DWX15, DW16, DW17, DW45, DW47, DW48 and other products, molded case air circuit breaker has DE20, CW1, S and other products.
China's accession to WTO, foreign products enter the domestic market, more representative of France, the United States, Germany, Switzerland, Japan and other countries, products, products in these countries represents a major technical performance of contemporary products, the highest level of air circuit breakers.
A new generation of products, short-circuit breaking capacity indicators have been very difficult, it can be said is much higher than the actual needs. 100 ~ 150kA short-circuit current can not be applied in practice, has become a competitive business indicators. From the forms of protection of view, most of the products has been achieved intelligence, protection is sound and can meet a variety of application requirements. The advanced circuit breaker with a communication interface products provide access, support a variety of fieldbus. The past two years, Hanover Industrial Fair in Germany, reflected on the situation is generally the case, the more unique products are Schneider NT16N1 products, their rated current 1600A, Dimension is now published on an international level the same current circuit breaker frame size of the smallest in the shell, but only a short-circuit breaking capacity 42KA (400V).
Siemens SentronWL circuit breaker is characterized by the whole family, with three shell frame level, each is integrated and independent structure (without the use of a very similar assembly-type), thus narrowing the large current (6300A) in the form of class size, and improve the the product reliability.
Circuit breaker from abroad, the development of perspective, drawing on aspects of domestic enterprises should have the following points:
An increase circuit breaker Ics, sought to Icu = Ics. Users generally recognized Ics, do not accept Icu in the selection of circuit breakers. From the manufacturing perspective, Icu and Ics both are equal, to simplify testing, reduce the number of guinea pigs. This circuit breaker manufacturers in China a large number of the actual situation is more economic sense. For Icu = Ics, should increase the value of Ics. This requires from two aspects: First, improve the interrupter systems to reduce the contact burns. Second, is to develop pit wear contact materials, contact materials required to withstand three major short-circuit breaking capacity tests, contact resistance stability.
2, reduced form factor. Dimension reduction is to increase the product's economic indicators, whether it is universal-type or MCCB should be the case. Now narrow the large capacity (6300A) circuit breaker width of great significance, using the shell frame level independent structure (without the use of phase pole assembly) is to narrow the width of the effective measures.
3, MCCB 1600A should develop the following products. From the national development situation, the focus should be the development of the following MCCB 800A to create a good bi-metal thermal magnetic MCCB is essential that this product structure is simple, cheap and very welcomed by the users .
4, circuit breaker and large-capacity (400A and above) MCCB should be the development of intelligent products, with communication interface supports a variety of field bus, in order to meet the requirements of a modern distribution automation.
