LV Kumuka Kusungwa Mukurwisa Mheni
Kuwedzera vanosunga vachipokana nemheni
Tsananguro yekumisikidza
Iyo saiti ine mahofisi (macomputer Hardware, magetsi, uye kudziyisa unit), yekuchengetedza post (moto alarm, burglar alarm, mukana wekuwana, vhidhiyo kuongorora) uye zvivakwa zvitatu zvegadziriro yekugadzira pa10 mahekita mu Avignon dunhu reFrance (mukana wemheni kuita 2 kurova pamakiromita2 pagore).
LV Kumuka Kusungwa Mukurwisa Mheni
Kune miti nemarata esimbi (pylons) padyo nenzvimbo iyi. Zvese zvivakwa zvakagadzirwa nemheni conductor. MV neLV magetsi emagetsi ari pasi pevhu.
Mufananidzo 1 - Dhizaini yekuisa kune vanoverengeka vanosungwa mukukasira
Matambudziko akasangana
Dutu rakarova saiti, ichiparadza iyo LV kuisirwa mune yekuchengetedza posvo uye ichikonzera 36.5 kE yekushandisa kurasikirwa. Kuvapo kwemakondakita emheni kwakadzivirira chimiro kubva pakubata moto, asi michina yemagetsi yakaparadzwa haina kudzivirirwa nevasungwa, zvichipesana nezvakakurudzirwa mumatanho UTE C-15443 uye IEC 62305.
Mushure mekuongorora equipotentiality uye earthing yemagetsi system, ichiteverwa nekusimbiswa kwekuisirwa kwemheni maconductor uye kuongorora kweanokoshesa epasi ma electrode, sarudzo yakatorwa yekumisikidza ma surge arresters.
Vakawedzera vakasungwa vakaisirwa kumusoro kwekuisirwa (main LV distribution board) uye mukukwiridzira mune yega yega chivakwa chekugadzira (ona mufananidzo 1 pamusoro). Sezvo kwazvakarerekera poindi yekubatanidza yaive TNC, dziviriro yaizongopihwa mune yakajairwa modhi (pakati pezvikamu nePEN).
Mufananidzo 2 - Yakadzika voltage kuwedzera vasungwa
Mufananidzo 2 - SPD Rudzi rwechipiri uye rwechitatu - Kuwedzera / kunonoka kwekudzivirira simba remagetsi kudzivirirwa
- In (8 / 20µs) kubva pa5 kA kusvika 60 kA
- IMax (8 / 20µs) kubva pa10 kA kusvika 100 kA
- Up kubva pa1 kV kusvika 2,5 kV
- Uc = 275V, 320V, 385V, 440V, 600V
- 1P kusvika 4P, 1 + 1 kusvika 3 + 1
- Monoblock uye pluggable
- TT, TNS, IT
- Inoyerera shanduko yekuonana
Mukuenderana negwara UTE C-15443 zvine chekuita nekushanda pamberi pemakondakita emheni, hunhu hweLSP (Arrester Electric) SPDs SLP40 uye FLP7 vanosunga vanosunga ndeanotevera:
- Pamusoro wegadziriro
In = 20 kA, iniMax = 50 kA, Up = 1,8 kV - Mukubvaruka (ingangoita 10 m kure)
In = 10 kA, iniMax = 20 kA, Up = 1,0 kV
Mune iyo Cascade, kudzivirirwa kwakanaka kunopihwa kune echipiri magodhi ekuparadzira (mahofisi uye yekuchengetedza posvo).
Sezvo iyo yekusarerekera poindi yekubatanidza yakashandurwa kuita TNS, dziviriro yaifanirwa kupihwa zvakajairika modhi (pakati pechikamu uye PE) uye musiyano maitiro (pakati pezvikamu uye kwazvakarerekera). Midziyo yekubvisa, mune ino kesi, ndiwo mabhureki emagetsi ane simba rekutyora kwe 22 kA.
Dzidziso // Kuisirwa kweSurge Mudziviriri
Iyo Vhidhiyo inoratidza kuisirwa kwakaringana kwekudzivirira kwekuwedzera, kusanganisa pamwe nechengetedzo yekuchengetedza (redunhu mudariki). Iyo "50 cm wiring mutemo "tsananguro ichakubatsira iwe kunzwisisa chaiyo wiring zvinoenderana neyakajairwa standard IEC 60364-5-534.
