Pfupiso Yakadzama yeZviratidzo zveMhosva dzeCable

Tsananguro yeChigadzirwa

Chiratidzo che "grounding short circuit two-in-one" chine matavi akawanda uye zvikanganiso zvinowanzoitika. Kuwana zvikanganiso zve "line faults" kunonetsa vashandi vanogadzirisa tambo dzemagetsi. Kuwana zvikanganiso zve "ground fault" dzimwe nguva zvinotora hafu yezuva, uye vamwe vanozviwana husiku mangwanani, uye vamwe muInner Mongolia. Kuti uwane mazuva mashoma. Saka, kuiswa kwechiratidzo che "fault indicator" kunogona kuvandudza kuvimbika kwesimba remagetsi, kuderedza simba revashandi, uye kupfupisa nguva yekudzima kwemagetsi.

Zvimiro:

1. Ipa rubatsiro uye nyore kugadzirisa matambudziko panguva yekukundikana kwetambo.
2. Zvichienderana nehukuru hwemutoro wemutsetse uye kupararira kwemafambiro emutsetse, nzvimbo yakakodzera yekuisa chiratidzo chekukanganisa inosarudzwa.
3. Kana mutsetse wacho uchishanda zvakanaka, chiratidzo chacho chinenge chiri mumamiriro ekugadzirisazve pasina chiratidzo.
4. Kana paine dambudzo pfupi kana kuti dambudzo repasi mumutsetse, chiratidzo chinotenderedza ndiro yechiratidzo masikati uye chinoita sechiratidzo chealamu chitsvuku; vashandi vanogadzirisa dambudzo vanogona kuwana nzvimbo yedambudzo zvichienderana nemamiriro echiratidzo.
5. Nguva yakatarwa yekugadziriswazve kwechigadzirwa mumafekitori i12h (nguva yekugadzirisazve inogona kugadziriswa zvichienderana nezvinodiwa nevatengi).
6. Chigadzirwa ichi chinopa rubatsiro rwakasimba pakugadzirisa matambudziko emutsetse uye zviri nyore kuziva nzvimbo yedambudziko.
7. Kupfupisa nguva yekudzima kwemagetsi uye kuwedzera simba remagetsi.
8. Hapana chikonzero chekudzima kuiswa kwechigadzirwa, maturusi ehunyanzvi ekuisa anopiwa mahara, uye kupatsanurwa kwacho kuri nyore.

Nheyo yeChigadzirwa

Kuona ma "short-circuit": Dunhu rekuona ma "short-circuit" rinochinja kamwe kamwe magetsi kana paine "short-circuit fault", uye kukosha kwe "short-circuit" kwakakura kupfuura kukosha kwakati (kunogona kuiswa zvichienderana ne "relay protection setting") mukati menguva yakati kuti magetsi adzime.
Kuona pasi kunoona shanduko dzemagetsi, ma capacitor currents uye mamiriro echikamu pakuisa pasi, kuona shanduko dzeharmonic, uye kuona zvakakwana kana pasi pacho pakaitika.

Iyo 15kV 200Achivharo chekudzivirira chakaputirwachikamu chekuwedzera chebhandi remvura. Rinopa chifukidziro chekudzivirira kupisa kwebhandi remvura uye chifukidziro chinodzivirira guruva uye chinodzivirira hunyoro kune majoini asina kuchajwa.

Iyo 200Achivharo chekudzivirira chakaputirwainogona kuiswa pamabushing e200A, mabhazi uye michina yekurembera pamadziro. Kana mabhazi nemajoini etambo zvakachengeterwa nzvimbo dzekurembera, zvinofanirwa kuvharwa nemavharo e200A ekudzivirira kupisa.

Chidziviriro chekudzivirira: Fomura yakasiyana uye tekinoroji yekusanganisa inoita kuti rabha yedu yekudzivirira yeEPDM yakagadzirwa ive yemhando yepamusoro.
Rutivi rwekunze rwe semi-conductive: rabha yeEPDM conductive yakagadzirwa yakagadzirwa inosangana nechiyero cheIEEE592.
Ziso rekugadzika: ziso rekugadzika rakabatana nechikamu chekunze chinofambisa mvura, chinoshandiswa kugadzika chigadzirwa.
Mhete yekushandisa: Mhete yekushandisa yesimbi isina ngura yakagadzirwa nechidimbu chimwe chete ine nzvimbo dzekugadzirisa masipiringi.

Zvinobatanidza zvemhando yeEuropean style 630A cross-shaped neT-shaped zvinonyanya kushandiswa pakubatanidza switch bus ye ring network cabinet, zvichienderana ne standard bushing ye switch cabinet, uye zvakakodzerawo kuma branch boxes ane switch. Switch cabinet yakadzivirirwa zvizere uye yakavharwa zvizere, ichidzivirira zvachose zvikanganiso zvinouraya zvinokonzerwa ne high-voltage exposure mumamiriro ekunze akaipa. Chigadzirwa chakagadzirwa ne busbars ne D uye cross joints chinonzi busbar system, inova ndiyo scheme inodiwa ye ring network cabinet. Zvakanakira zvikuru ndeizvi: mutengo wakaderera uye kushanda kwakavimbika. Kureba kwebus bar kunogona kugadziriswa zvichienderana nezvinodiwa nemutengi. D uye cross connections zvinogona kugadzirwa kuita zvigadzirwa zvakachengetedzwa kana zvisina kudzivirirwa zvichienderana nezvinodiwa nemutengi.
