Mhinduro dzezvivakwa.

Kuwedzera - njodzi isingafungidzirweKuvhiya injodzi inowanzotarisirwa pasi. Aya mavoltage pulses (transients) anongotora sekondi yakakamukana anokonzerwa nekurohwa kwakananga, pedyo uye kure kure nemheni kana kushandura mashandiro echinhu chemagetsi.Mheni yakananga nepedyo inorova Mheni yakananga kana iri pedyo inorova mheni muchivako, iri padyo kana mumitsetse inopinda muchivako (semuenzaniso low-voltage power supply system, telecommunication uye data lines). Iyo amplitude uye simba remukati mezvinokonzeresa mafambiro emhepo uye impulse voltages pamwe neinosanganisirwa magetsi emagetsi munda (LEMP) inotyisidzira zvakanyanya sisitimu kuti ichengetedzwe. Mheni yemheni inokonzerwa nekurova kwemheni yakananga muchivako inokonzeresa kukwira kwehuwandu hwe100,000 volts pamidziyo yese yevhu. Kuwedzera kunokonzerwa nekudonha kwevoltage pane yakajairwa earthing impedance uye zvinokonzeresa kusimuka kwechivako zvine chekuita nenharaunda. Uku ndiko kunetseka kwakanyanya pamagetsi emagetsi muzvivakwa. Pamusoro pekudonha kwevoltage payakajairwa earthing impedance, masurges anoitika mukuiswa kwemagetsi kwechivako uye mumasisitimu akabatana nemidziyo nekuda kweiyo induction mhedzisiro yemheni yemagetsi emagetsi. Simba remasurges aya anokonzeresa uye zvinokonzeresa mafambiro emhepo zvakaderera pane izvo zvemheni yakananga. Kure mheni inorova Kure mheni inorova are lightning strikes far away from the object to be protected, in the medium-voltage overhead line network or in its close proximity as well as cloud-to-cloud discharge. Kuchinja mashandiro Kuchinja mashandiro of power utilities cause surges (SEMP - Switching Electromagnetic Pulse) of some 1,000 volts in electrical systems. They occur, for example, when inductive loads (e.g. transformers, reactors, motors) are switched off, arcs are ignited or fuses trip. If power supply and data lines are installed in parallel, sensitive systems may be interfered with or destroyed. Kudzivirirwa kwesimba rekupa uye data system Kuparadza kunopfuura munzvimbo dzekugara, hofisi uye manejimendi zvivakwa uye maindasitiri maindasitiri anogona kuitika, semuenzaniso, magetsi emagetsi system, ruzivo tekinoroji system uye nharembozha, kudzora masisitimu ezvivakwa zvekugadzira kuburikidza nefieldbus uye ma controller eair-conditioning kana magetsi masisitimu. . Aya masisitimu anonzwira tsitsi anogona chete kuchengetedzwa neyakadzama yekudzivirira pfungwa. Muchirevo chechinyorwa chino, kushandiswa kwakarongeka kwemidziyo yekudzivirira yekuvhiya (mheni yazvino uye surge arresters) yakakosha. Basa rezvibatiso zvemheni nderekuburitsa masimba makuru pasina kuparadzwa. Ivo vakaiswa pedyo sezvinobvira kusvika panzvimbo iyo magetsi emagetsi anopinda muchivako. Masurge arresters, uyewo, anodzivirira materminal equipment. Ivo vakaiswa padyo sezvinobvira kumidziyo inochengetedzwa. Iine mhuri yayo yeRed/Line chigadzirwa chemagetsi emagetsi masisitimu uye yayo Yero / Mutsetse chigadzirwa mhuri yedata masisitimu, THOR inopa yakabatana ekuvhiya michina yekudzivirira. Iyo modular portfolio inobvumira mutengo-wakagadziridzwa kuitiswa kwemaitiro ekudzivirira kune ese marudzi ezvivakwa uye saizi yekuisa.
