Chimateteza mphasa: zosiyanasiyana, quality, cholinga

Chimateteza mphasa ntchito ngati muyeso zina chitetezo pamene ntchito ndi mkulu voteji makhazikitsidwe magetsi. chuma chimene mankhwala ayenera kukwaniritsa ziyeneretso. Malinga ndi zolinga osankhidwa kukula zinyalala, ndiponso amaganizira nthawi yosungirako mu kugula, ndilo kwenikweni ndi zaka zitatu.

zinthu kusankhidwa

Chimateteza mphasa ndi njira zina chitetezo. Mkulu angathe mukhoza nkhonya zida payekha: magolovesi, nsapato, ntchito ndi zizindikiro panopa kuyeza zida. Mu malo ungrounded zitsulo waima kapena chinyezi pansi miyeso n'zofunika kwambiri.

Malamulo a ntchito magetsi voltages wa ku ndi pamwamba 1000 V mankhwala kuvomerezedwa ntchito mphasa dielectric. Pamene akugwira voteji yapamwamba iliyonse pansi pa mapazi a ndodo saizi pakati padziko chuma chapadera. Ndi kugonjetsedwa osati angathe, komanso mafuta, makina avale.

Zimafunika mankhwala oteteza

Chimateteza mphasa akwaniritsa zofunikira za zikalata zolimbana: GOST 4997-75. Mankhwala zinthu kupirira lalikulu kupinda mkombero. Alumali moyo katundu ndi zaka 3, ndiye Mpofunika kusintha mankhwala. Ichi ndi chifukwa katundu wa mphira zikuchokera kusintha mchikakamizo cha mpweya: dubeet kumakhaladi Chimaona, wotaya mphamvu yake kupeza pamwamba.

Pamwamba pa mphasa ndi corrugated ndi kupulumuka, poyambira akuya ndi za 1-3 mm. zakuthupi amatha kupirira voltages 20 kV pa pafupipafupi 50 Hz. Anayeza kutayikira panopa zomwe si upambana 16 Ohm A / sq. m. Kapangidwe ka maonekedwe akhale kwenikweni izo chimakhala chogwidwa ndi kamvekedwe mdima.

Zosiyanasiyana njira zodzitetezera

Zamgululi anawagawa mitundu zotsatirazi:

• Ochiritsira dielectric mphasa, mtengo zolimbitsa thupi ndi otsika, ndi moyo utumiki yochepa.
• Maslobenzostojky ntchito mu mapangidwe zikuwononga. Nthawi zambiri anali kuika pa choyikapo.

Malinga ntchito amodzi kukula mphasa dielectric. Mtengo zimadalira kukula. Zamgululi zidzasankhidwa ndi makhalidwe muyezo:

• M'litali 500-1000 mm. Pangakhale zoposa 1000 mamilimita ndi ku 8 mamita Mtengo -. 100 mpaka 500 rubles.
• M'lifupi - 500-1200 mm.
• Makulidwe - 6 ± 1 mm.

Apadera chimateteza mphasa amagulitsidwa pa mtengo pamwamba rubles 500. Imani, malingana ndi Baibulo, kodi ndalama zikwi zingapo. Wapadera mankhwala pa pempho (malinga ndi zojambula makasitomala a) ndi contractual malipiro ndi mfundo za kupanga.

Mu mapangidwe chinyezi, izo tikulimbikitsidwa kugwiritsa ntchito zokutira zitsulo kumbali. Ndi dielectric pamwamba pa chinthu chimodzimodzi mkulu anakonza pa miyendo ya nkhani yofanana. Kutalika kwa nkhani imayamba ndi 70 mm. Yazokonza pansi kufala kwa midadada nkhuni ndi kusiyana oposa 30 mm. Pakuti miyendo ntchito insulators wapadera ndi CH-6. chitetezo zina atha kutumikira ngati mphasa labala, kumalumikiza padziko choona.

Chongani zodzitetezera

Mphira mphasa dielectric ndi chofukizira zokutira zitsulo imvera nthawi kusokonezeka matenda ndi kukhulupirika kwa zipangizo. Pamaso ntchito ndi mapadi anayendera, afufuze kwa ming'alu m'nkhaniyo ikuchitika pa unakhota dongosolo pulasitiki. Kulimba tikulimbikitsidwa kuyendera pamaso pa tchipisi pa miyendo ndi zinyalala.

Ngati zopindika makalipeti, floorings ndi zipangizo zina zodzitetezera ayenera m'malo. Ngati maimidwe sizimawasuntha, ndiye matenda ikuchitika kamodzi pa zaka 3. Ngati chilema akhoza kuchotsedwa, m'pofunika kuti achite mayeso dielectric pa chitsanzo malinga ndi malamulo a.

Osati kuti chimachititsa avale msanga wa ❖ kuyanika mphira, Ndi bwino kusunga malamulo otsatirawa ntchito mankhwala:

• mphasa yosungirako ikuchitika pa kutentha madigiri 20-25.
• Musanagwiritse ntchito zokutira amene anabweretsa ku ozizira, muyenera kuwapatsa otentha mu malo otentha kwa tsiku.
• Aliwonse padziko mwachindunji mwayeretsa popanda kugwiritsa ntchito njira mowa kwa matayala osati zadubela.
• Ndodo sayenera kugwiritsa ntchito chonyowa ❖ kuyanika ntchito.
• M'madera ozizira ntchito yapadera chimateteza mphasa, magolovesi, coasters. Pali mankhwala chingathe kupirira kutentha kwa madigiri -50 kuti +80.

njira zina chitetezo

Pamene ntchito mu makabati mkulu-voteji ndi winch magetsi chofunika kugwiritsa ntchito zipangizo lotsekedwa:

• Magolovesi ntchito osati kwa miyezo, owotcherera amavalira kupeza kuchokera pansi;
• nsapato, nsapato za jombo, galoshes;
• chimateteza ndodo kuona magawo magetsi;
• kuvala chigoba zoteteza chofunika kuteteza maso;
• chisoti pulasitiki chikukhudza dielectrics;
• akanema apadera ndi Arc magetsi;
• pa mbali azima conductive m'dera ntchito, ophimbidwa insulators mphira.

Ndodo kutumikira mkulu-voteji makhazikitsidwe, apereke apadera kutentha zosagwira masuti. Ntchito pa msinkhu ntchito makwerero ndi stepladders ndi oyika dielectric.
