PS/PSN 25-66KV 3-12.5KN Post type porcelain insulator yekunze high voltage Power line

Porcelain post insulators for high-voltage lines A line post insulator insulator yesimbi ine imwe kana akawanda insulators yakanamirwa zvachose panheyo yesimbi, dzimwe nguva ine chivharo, uye inogona kuiswa kaviri pachigadziko chesimbi.Iyo bhaudhi yemusoro kana imwe kana akati wandei mabhaudhi akasimirirwa zvine simba pane inotsigira chimiro.Inoshandiswa kuvhara uye kutsigira waya mumagetsi emagetsi eAC ane zita remagetsi akakwira kupfuura 1000V, frequency isina kukwira kupfuura 100Hz, uye urefu husina kukwira kupfuura 1000m.pakati pe40°C.Mutsetse (wakasimba) post insulators unogona kutsiva pini insulators.Pini insulators ndeye B-mhando insulators, iyo inowanzoitika kuparara uye kukuvara panguva yekushanda.Yakaomeswa girazi insulators ichazviparadza yega panguva ino, nepo porcelain insulators haizodaro.Naizvozvo, dhipatimendi reindasitiri yemagetsi richashandisa mari yakawanda yevashandi uye zviwanikwa kuita ongororo yemagetsi uye bvunzo dzekudzivirira pane porcelain insulators, iyo ine zvimwe zvinokanganisa maererano nehupfumi uye yakachengeteka magetsi.Naizvozvo, nekuvandudzwa kwehunyanzvi hwekugadzira, mutsara (wakasimba) post insulators wakaonekwa.Iyi insulator ine yakasimba insulator uye imhando yeA insulator, saka hapana chikonzero chekunetseka nezvekuputsika pamwe nemukati meiyo insulator panguva yekushanda, iyo inonyanya kukosha kwayo.
Line pillar porcelain insulators yakakamurwa kuita mamakisi masere e95, 105, 125, 150, 170, 200, 250 uye 325kV maererano neyakayerwa mheni impulse inomira kukosha kwevoltage;zvinoenderana neyakayerwa kukotama kutadza mutoro kukosha, ivo vakakamurwa kuita 3, 5, 8 uye 12.5kN mamakisi mana;maererano nekugadzirisa nzira, yakakamurwa kuva marudzi maviri: vertical installation uye kuenzanisa kuisa;maererano nenzira yekubatanidza ne-high-voltage waya, yakakamurwa kuva marudzi maviri: mhando yekusungirira yepamusoro uye yepamusoro yemhando ye clamp;maererano nzira yekubatanidza pakati pesimbi tsoka uye chigadziko, iyo yakakamurwa kuva detachable Type (threaded connection) uye isingaparadzanisiki mhando mbiri.
Tsanangudzo yemuenzaniso:
PS——mutsara positi mhando porcelain insulator;
J——<em>clamp type, rudzi rwekusunga harwuna kuratidzwa;
N-yakareba creepage kureba (yakajairika creepage kureba haina kuratidzwa);
nhamba inotevera "—" zvinoreva mheni yakazara wave Impulse inomira kukosha kwevoltage, kV;
Nhamba inotevera "/" ndiyo inokotama kutadza mutoro kukosha, kN;
Z-kuiswa kwakatwasuka, kuisirwa kwakatwasuka hakuna kuratidzwa;
S-shinda yekubatanidza.
GB/T 21206-2007 yakajairwa inotara:
R——line post insulator;
Nhamba iri shure kweR inoratidza kukotama kutadza mutoro kukosha, kN;
iyo inotevera tsamba E kana J inoratidza kunze kana mukati mepurasitiki kuiswa kwesimbi yesimbi;zvinotevera
mabhii T, C, uye H anoratidza mhando yekusungirira yepamusoro uye yakasimudzwa yakasimudzwa simbi yekumusoro zvichiteerana mhando kana mhando yesimbi yekumusoro yakaiswa yakachinjika;
iyo nhamba yekuwedzera inoratidza iyo yakatsanangurwa mheni yekumanikidza inomira voltage kukosha, peak kV.
