   The corporation havees the scientific research personnel staff of well-developed tabrication installation and classic ,Devote self to painstakingly the development together with development of twin power source ATSs 。Twin route power source autonomous switchover button and together with it necessary intelligent display of such dominant produce ,Chiefly be applicable to higher level's building 、Post and telecommunications news dispatch 、Coal mine 、Boats and ships 、Military facilities 、The industry pipleline awaits need not to be interrupted the power supply situation ,Be living below what in the way of the electricity sharply add the sure tendency of town ,Still more be able to meet the taller demand in the way of the electricity dependability 。 2004Year the particular Mo lux science and technology limited company of Beijing Lai shall the pool capital against the corporation open up giving birth to twin power source ATSs to reach to mold the casing circuit breaker together ,This has been two further cooperations and development since working together in 2000 of corporation 。

Twin power sourcies
Produce property:
Have the contact that old and young divides ,The intermediate OFF place may avert surely trading in the process instant The abnormal voltage comes into being 。Adopt the contact special ,Consist of main contact and the extinction of arc contact , Adopt the silver-colored wolfram compound metal 。


Instant stimulates magnetism the means ,Stimulate magnetism time :
A's side :The input time 55ms ,Call clear downtime 20ms
B's side :The input time 80ms ,Call clear downtime 20ms
The excellent branch snaps the capability ,That the contact finger stands the electric current act as 1.8 -fold of MCCB 。
Havees self flings since reaches again self flings not since replys the meritorous service capacity
Have locking OFF's position functions
 
Liquid crystal intelligence control utensil property :
The judgement power source normality is whether or not
Have five Duan Yanshi ,Yan Shi time shifts
Have tension 、Be behind with the tension protection meritorous service capacity
Lacking one another safeguards the meritorous service capacity
“Electrified wire netting —Generating set ”Signal contact
Xi'an Xi Pu electric power electron limited company
 The Xi Pu electric power electron limited company in Xi'an is specialized manufacture figure style soft start STR and the frequency converter tall science and technology business of modernize 。Such manufacture STRA 、STRB、STRC's set soft start not merely havees the well performance ,But also sufficiently consider use and the purchase situation in domestic marketplace ,Cause such produce have the exceedingly high capability adapting to 。
The particular Mo lux science and technology limited company of Beijing Lai is since 2000 since the STR's set soft start that the deputy Xi'an Xi Pu electric power electron limited company gived birth to ,Such produce is subjected to the wide-ranging high opinion of marketplace ,In the interest of two corporation long-term is cordially workd together and is settleed the well base 。


Main produce sort
  一.STRA's hanging style
 · Meritorous service rate limit :     7.5~75KW
 · Tension rank : 380V、660V
 · Shelter rank : IP20

  二.STRA's clothes closet style
 · Meritorous service rate limit :     90~800KW
 · Tension rank : 380V、660V
 · Shelter rank : IP20



  三.STRB's hanging style
 · Meritorous service rate limit :     90~800KW
 · Tension rank : 380V、660V
 · Shelter rank : IP00


Employ the conditional sum to come into being the criterion :
  Rule produce use term
  · Power supply power source :Local junction circuit 、Provide for self
    electrified wire netting 、Diesel oil dynamo ;The three-phase interchanges
    380V either 660V (–10%,+15%),50HZ。
 · Use electrical machinery :Asynchronous electric motor of ordinary
   squirrel-cage 。
 · Start frequency :May act as frequently either does not frequently start ;
   Propose per hour overtakeing 20 times 。
 · Cooling means :Natural wind is cooled either forced air cooling 。
 · Installation means :Two kinds of style in hanging style and the clothes closet 。
 · Shelter rank :IP20 either IP00 。
 · Ambient condition :
  The height above sea level overtakees 2000 meters ,Ought to employ by the relevant degradution capacity 。
The environment temperature is living –25~+40Between OC 。
Relative humidity :Not overtake 95% (20oC±5oC),Does not there is not the fruit or leaves cogulateing 。
Does not there is not Yi Ran 、Yi Bao 、Corrosiveness gas ,Does not there is not the dirt electrically conducting 。
Indoor location ,Ventilation is well 。
The vibration is smaller than 0.5G
Notes :The non- rule produce of term need to be specially employd ,Please being living proposes the concrete technique demand when placeing an order for goods 。

Accords with the criterion :

Intelligent electrical equipment limited company of Zunyi City long march :
  CB11(DW48)The intelligent circuit breaker is being living the tremendous expenses of in 1 9 9 4 long march electrical equipment National day mill input ,Depend the technical personnel of oneself researchs and develops domestic first intelligent circuit breaker that havees the current well-developed level ,The success is prepareed to full set through 630A up 3800A of 4 years up 6 years ,6 years by country economy trade commission specialist being examined and appraise firmly believes in the interest of the fresh produce of country grade ,Gao Xin that the country by country economical trade committee specialist is examined and appraise to firmly believe in the interest of 9 7 by the all-powerfull style circuit breaker of intelligent mould of CB11-3200 produce ,Simultaneous CB11-1600 、CB1103200 is by the Guizhou economy trade commission 、The Guizhou technical supervision bureau is confirmed in the interest of the Guizhou country famous brand produce ,2002Year on September 14 by means of ISO9001 、2000The quality setup is attested ,2003The year attests by means of CCC in April 。
  CB11-1600、3200The all-powerfull style circuit breaker of intelligent mould low pressure is applicable to exchange 50HZ ,Under the rated work tension 690V ,In rated work electric current 3200A and the below distribution electric network ,Used for distributing electric power and protection line and power source installation to dispense with to accept the load factor 、Be behind with tension 、Short circuit 、Grounding mishap danger ,Being living also may do worthwhile the protection electric motor to employ below the regular term 。Have the exact choice protection meritorous service capacity ,The power supply dependability may be liftd ,Averts unnecessarily power failure 。
