Direction of development of key of our country low-pressure electric equipment d

Industry of our country low-pressure electric equipment appears the main task of level, it is to quicken the development of product of the 3rd acting high-powered low-pressure electric equipment to be perfected as soon as possible above all, make its seriation, increase promotion strength to develop the 3rd acting product quickly at the same time. The specific target that develops the 3rd acting product is: Improve product of our country low-pressure electric equipment overall level, narrow with the country heterodyne is apart from; Raise market of product of high-grade and homebred low-pressure electric equipment to have rate; System of contented and low-pressure distribution, control and device and form a complete set of national major project need; Improve reliability of product of electric equipment of our country main low pressure and exterior quality apparently. From at present development state of affairs looks, should develop mainly the following product of 8 kinds of big electric equipment: Intelligence changes frame breaker; Intelligence changes model carapace breaker; Communicate contactor; Low-pressure vacuum breaker; Protector of electronic type electromotor, starter (include soft starter) ; New-style terminal electric equipment (the key develops) of low-pressure surge protector; Control and protective switch electric equipment. Dominant product should pull open class 　 to be demand of contented and different user, part of one's job of development of main series product is low-pressure electric equipment advanced model, taller model, economy is practical model 3 class. 3 class product should develop at the same time, need actually with convenient user basis reasonable choose. Advanced model: The 3rd acting product can serve as our country at present level (5~10 year) product of electric equipment of low pressure of high quality scales. Taller model: With our country product of the 2nd acting low-pressure electric equipment gives priority to body, at the same time product of this one class should need to undertake 2 times developing according to the market. Like science of Shanghai electric equipment the institute is opposite product of series of DW15 of all-purpose type breaker undertakes 2 times developing, model of the product after be being developed 2 times is DW15HH; CJ40 series communicates contactor to also can serve as CJ20 series 2 times to develop a product. The objective that has 2 times developing basically is to improve product performance, add our country the market competition ability of product of intermediate and low-pressure electric equipment, the home made product outside holding off to our country low pressure electric equipment is intermediate product market is permeated. Economy is practical model: Should perfect our country new generation economy is practical model the product tries hard to popularize, with quickening generation of our country backward product falls into disuse. The key has caught all-purpose style contactor of breaker, model carapace breaker, communication, hot relay 4 kinds of big products. The product that extends as industry stress is: All-purpose type breaker replaces breaker of carapace of DW10, model to replace contactor of DZ10, communication to replace CJ10, hot relay to replace JR16 with JR36 with CJT1 series with SC series with DW16. Economy of development new generation is practical model the product is to get used to different class the user asks above all, it is development strategy need, not be expedient, also not be to transfer product, its need is long-standing. Can quicken generation of our country next of backward product eliminate step, but it is not generation lags behind the reprint that washs out a product. Return additionally can fill part enterprise washs out the generation that still producing at present after backward product " vacant " . According to afore-mentioned purposes, new generation economy is practical model the product should follow principle of the following design: 1. Maintain the characteristic with generation product simple, low-cost structure of our country, economy of requirement new generation is practical model product production cost and generation product comparative, do not exceed 5%~10% commonly. 2. The product installs dimension and over all dimension to keep changeless as far as possible. 3. New generation economy is practical model product relatively generation product is due on function or function rise apparently. 4. Answer to overcome or be improved to the visible defect that exists on structure of generation product and function. 5. Perfect series norms, develop derive set, the accessory with necessary development or form a complete set. 6. Accord with standard of electric equipment of our country active low pressure and IEC standard. Notable is, in generation product of series of main product DW10, DZ10, CJ10, JR16 falls into disuse formally hind, afore-mentioned many companies are right washing out the product is changed through simple product appearance and model, the way that change the appearance puts the market on afresh cannot be taken. Explore 　 of the 4th acting product actively to trying hard to develop the 3rd acting product to be pushed stage by stage in our country to the market while, company of electric equipment of foreign main low pressure from 20 centuries 90 time later period begins to roll out updated new product ceaselessly again. New generation product is changed besides high-powered, miniaturization, electron, intelligence is changed, modular, combination is changed outside, its are main the feature is but communication, tall it is reliable, good to defend performance, accord with environmental protection to ask to wait. Especially new generation product can join with system of spot bus line, realize network. It will from go up at all the low-pressure distribution that changes a tradition and control system and its device, give infuse of product of traditional and low-pressure electric equipment new and high technology at the same time, make function of product of low-pressure electric equipment produces qualitative leap. As our country the development of product of the 3rd acting low-pressure electric equipment and application, difference of advanced level of product of our country low-pressure electric equipment and abroad already shortened to 10 years. If product of low-pressure electric equipment is in,can correspond technical respect does not catch up with, so afore-mentioned difference will be pulled afresh big. And, this one difference is the difference on product function discretion not just, the difference that pledges on product function however. It will make product of our country low-pressure electric equipment is in distribution of prospective low pressure and control system lose market competition ability completely. The foreground after our country intelligence changes low-pressure breaker to put in the market in domestic promotion is valued all the time, a lot of designing institutes still put forward low-pressure breaker to bring the demand of communication interface in succession. Look from market sale status, the scale growth that asks breaker takes communication interface is very rapid, the system that a lot of users use at present does not ask to correspond, but the development that considers a system, ask obligate communication interface. The supervisory system growth that at present low-pressure distribution introduces spot bus line is very rapid, these systems need to be able to correspond product of low-pressure electric equipment, develop those who have our country own intellectual property to be able to correspond product of low-pressure electric equipment already extremely urgent. Be necessary to begin our country for this the development of product of the 4th acting low-pressure electric equipment. Current, the 3rd acting product still is continueing to develop in, if develop the 4th acting product, how to hold the different feature of two acting products, if why had handled the relation between two acting products, should cause the attention of worker of electric equipment scientific research.
