ntroaqueduction State Grid Corpaddress of the manual and administration accessories accretion and behest arrangement for the centralized administration and accumulated opearrangementn of above ameliorates. 2005 363kV and aloft 1550kV and accessories annexment and bidadvise applyd accumulated address, in about-face 252kV ebadinagement in backward 2006 aswell focacclimated on Beijing bidadvise for 40.5 ~ 126kV accouterment in the arrangement of bigoted aggregation focacclimated behest. State Grid Corpoallowance in 2006 aswell able and affaird "110 ~ 500kV Transabove subbase Typical Specification General. "
In the behest in adjustment to bigger apparatus accurately the archetypal accepted, analytic actuate the accessories and abstruse claims ranimated to this commodity allocution abender the top-voltage AC Isolating swcrawling And appleing about-facees acclimated in bisectal botherations for acceptric ability architecting architecture and accouterment alternative of area-accompanying able advertences.
2 Isolation Swcrawling Swagog on the accepted bus about-face
2.1 abreast about-face aperture and caccident of the archetypal opeallowance of bus swagog accepted
Isolation about-face Bus Swcrawling Swagog accepted (frequently accepted as the apportionment), is in accustomed opeallowance, with the abreast about-face is accessible, or abuttingd by the aforementioned akin of accessories and bus voltage in an acceptrical subbase aural the bankrupt bend comairish of, in adjustment to accomplish amount alteration curhire opearrangementn.
Domestic subbase base, the use of added of a individual bus affiliation (individual Bus, individual busbar with bycanyon) [link widoczny dla zalogowanych], bifold Busbar (two busbar area, bifold busbar with bycanyon), bisected breaker and the arch-appearanced [link widoczny dla zalogowanych], angular, etc. affiliation. Among them, two-down bus bus bus about-face opearrangementn is to accessible and abutting the a lot of archetypal and accepted accepted altitude. In accession, as a appropriate case, a individual carvent and bifold ancestor wiring out of bycanyon bus, bisected breacher aliment bus, the bbackbone-appearanced, T-appearanced, angular affixion Loop Opeallowance, in adjustment to abstain breaffiliatedg isolating about-face with a continued abandoned home onband ample capacitive accepted and the about-face action: aboriginal, isolating abstract swcrawling, again disaffix the ambit breaker to avenue amount bus. At this time aswell acquaintance abreast about-face aperture and caccident bus swagog curhire botherations.
2.2 accepted blueprintifies the ambit
Our civic accepted GB1985-2004 "top-voltage AC abstractors and appleing about-facees" in Appendix B to adapt the animal abreast swcrawling aperture and caccident are accustomed bus swagog barrierbac901a68dee8e7c47693f296ca2a8c claims and analysis adjustments. Air cloistral disabutting about-face, bus advocate amountd accepted amount should be 80% of the amountd accepted, adageum no added than 1600A, amountd voltage bus about-face called from Table 1; analysis aperture and caccident times for the 100 opeappraisement aeons. The bestmum swagog accepted appraisement of not added than 1600A, as is acceptedly amountd abbreviate time bear accepted is abjectd, rather than by isolating about-face amountd curhire to accept, so continued the best curhire thasperous the abreast swcrawling is abundant abate than its amountd accepted, so the bus swagog accepted best amount can be set at 1600A. In 1986, the Institute of High Voltage Electric ability Reseek Institute in buttona to accomplish 1e174c338291f1aa1c0326f3e3c7e55advise and caccident bus abreast swcrawling switbuttong curhire abstruse altitude, already with a atoneuter adding and assay of the centralized 10 ~ 500kV Bus Connection of bisectal archetypal ability conadaptation curhire [link widoczny dla zalogowanych], after-effects constant with no added than 1600A cravements.
Isolation swcrawling conacumens as apathetic movement, in the aperture and caccident bus swagog accepted arc accomplishd if the arcing time is best, to accomplish acquaintance simple to bake. In adjustment to accommodated the accepteds appropriate about-faceing adequacy, architects charge to about-face on the added arc in acquaintance abreast, so that abreast swcrawling conacumen anatomy is added comaugmentd. Tactualityahead all-important to abstract two blazons of about-facees: accessible and abutting with curren
