Ongorora iyo nheyo yezvokurapa yakanangana neTester Tester fr

Zvivakwa zvepamusoro-zvemagetsi zvemagetsi zvinofanirwa kuchengetedza zvakanakisa insulation panguva yekushanda, saka nhevedzano yekuedzwa kwekunzwa inofanira kuitwa kubva pakutanga kwekugadzirwa kwemidziyo. Iyi miedzo inosanganisira: Raw zvinyorwa mukugadzira maitiro, muedzo wepakati mukugadzirwa, chigadzirwa uye chefekitori yekuisa-site yekuisa bvunzo dzekudzivirira nekuvhiya panguva yekushandisa. Chipupuriro chemidziyo yemagetsi uye kuedza kwekudzivirira ndiyo nzira mbiri dzakanyanya kukosha. People's Republic of China Electric Magetsi Coldry Code Code uye National Code: DL / T 596-19996 "GB 501

2. Insulation Kudzivirira Kuedza

Kudzivirira kwekunzwa bvunzo yemidziyo yemagetsi ndeyekukosha kwekuti kuve nechokwadi chekushanda kwakachengeteka kwemidziyo. Mushure mekuedzwa, iyo insolation mamiriro emidziyo inogona kubatwa, njodzi iri muInternation inogona kuwanikwa munguva, uye kuchengetedzwa kunogona kubviswa. Kana paine dambudziko rakakura, zvinodikanwa kutsiva michina kuti udzivise kurasikirwa kwakashata, sekubuda kwesimba kana kukuvara kwemidziyo kunokonzerwa nekutadza kwekushanda panguva yekushanda.

Kuedza kwekudzivirira kwekudzivirira kunogona kukamurwa kuita mapoka maviri: Imwe ndeyekuedzwa kwekuedza kana kusimbisa maitiro ekuverenga, kusanganisira nzira dzekupokana, kusanganisira kuyananisa kupesana, kudzima zvazvino, Difectric Kurasikirwa Tangent, Etc. Ipapo sarudza kana iyo insulation ine chero zvikanganiso. Miedzo yakaratidza kuti nzira iyi inobatsira, asi haigone kushandiswa kuvimbika kuti isarudze simba remagetsi rekusimbirira. Iyo imwe bvunzo inoparadza kana bvunzo yekumanikidza. Iyo voltage inoshandiswa muedzo yakakwira kupfuura iyo yekushandisa voltage yemidziyo, uye zvinodiwa nekuedzwa kwekusimbisa kwakasimba. Kunyanya, pane njodzi yakakura yekufumura uye kuunganidza zvikanganiso, uye kuve nechokwadi chekuti kusimbisa kwemagetsi, kusanganisa ngochani, etc. Kuzvidzivirira kwechiitiko chokunyepedzera ndechekuti zvichaita kuti vamwe Kukuvadza kune insolation.

3. Electrical Equipment Handover bvunzo

Kuti tisangane nezvinodiwa zveinjini yemagetsi uye magetsi ekuisa mayedzo ekuongorora, uye kusimudzira tekinoroji mitsva yeMagetsi ekuongorora, magetsi " Zvirevo zvekuedza kwakasiyana siyana. Pamusoro peimwe insulation yekudzivirira kwekuedza, zvigadzirwa zvemagetsi kutsiva zvinoedza zvakare zvinosanganisirawo humwe hunhu hwekuedza, senge transformer the dc kupesana uye kuongorora kweCourtiki

4. Iyo yekutanga nheyo yekusimbisa kwekudzivirira kwekuedza kwekuedza

4.1 Insulation Kupokana bvunzo dzinopesana nekupesana bvunzo ndiyo inonyanya kushandiswa uye yakanyanya nyore chinhu muyedzo wekusimbisa kwemidziyo yemagetsi. Kukosha kwekungoparadzira kunogona kuratidza zvinobudirira kuringana nekuvhenekera, kwakadai sekunyorova kwakazara, kusvibiswa, nekuchembera uye kukwegura nekukwegura. Chimbo chakanyanya kushandiswa kwekuyedza kupokana kupokana ndeyekupokana kwekupesana (insulation kupokana tester).

Insulation Resterance Testers (inoparadzira testers) kazhinji ine marudzi akadai se100 volts, 250 volts, 500 volts, 2500 volts, uye zviuru zvina makumi mashanu, uye 5000 volts. Iyo insulation kupokana tester inofanirwa kushandiswa zvinoenderana neDL / T596 "Dziviriro Maitiro Ekuedza Kwemidziyo Simba".

4.2 LEAKAGE Yazvino bvunzo

Iyo voltage yeiyo general dc insulation kupokana tester yakadzika kupfuura 2.5kv, iyo yakaderera pane iyo yekushanda yekubatira yemidziyo yemagetsi. Kana iwe uchifunga kuti voltage yekuyera kwekuparadzira kweTester yakaderera, unogona kuyera kubhururuka kwazvino kwemidziyo yemagetsi nekuwedzera dc high voltage. Zvinowanzoitika zvishandiso zvekuyera kubhururuka zvazvino zvinosanganisira yakakwira-voltage transimental vatashi uye DC makiromita akanyanya-vhesi. Kana zvishandiso zvacho zvichizokundikana, kubhururuka kwazvino pasi pevhesi rakakura kupfuura iro riri pasi pepfungwa dzakaderera, ndiko kudzikisira kwepamusoro vhiza zvakanyanya pane izvo pasi pevhesi rakaderera.

Iko hakuna mutsauko mukuru pakati pekuparadza zvazvino uye kusimbisa kwekuramba kweiyo chirwere chokurapa tese tester kuyera michina, asi iyo yekudzima zvazvino kuyerwa kune hunhu hunotevera:

. Kupfupikiswa kwesimbe pachayo kunofumurwa nyore nyore, uye kumwe kukonzeresa zvikanganiso zvisina kupinzwa kunogona kuwanikwa.

4.3 DC Trated Voltage bvunzo

CC neSrated Veltage bvunzo ine kumusoro

Kukurukurirana kwakatiririsa kuedza kwemagetsi dzimwe nguva kunoita kuti zvimwe kushaya simba mukusimbisa kwakanyanya. Naizvozvo, zvakafanira kuitisa kuyedza pakusimbisa kwekusimbisa, kuwanda kwemari, kudzima zvazvino uye dielectric kurasikirwa pamberi pekuedza. Kana muedzo wekuyedzwa uchigutsa, kutaurirana kunotsungirira bvunzo yekuverenga voltage kunogona kuitwa. Zvikasadaro, zvinofanirwa kuitwa nenguva, uye kutaurirana kunotsungirira bvunzo yeVoltage kunofanirwa kuitwa mushure mekunge chinangwa chimwe nechimwe chinokwanisa kudzivirira kukuvara zvisina basa.

4.5 Muedzo weDilelectric Kurasikirwa Factor Tgδ

Iyo Difelectr Kurasikirwa Factor Consor Tgδ ndiyo imwe yezvinangwa zvakakosha kuratidza maitiro ekusimbisa. Iyo dielectric inoridza factor tgδ inoratidza hunhu hweparamende yekunzwa kurasikirwa. Zvinogona kushingairira kuisirwa zviyero zvakazara zvemidziyo yemagetsi zvakakanganiswa nekunyorova, nekuora, uye kushatisa, pamwe nehurongwa hwemunharaunda madiki-akakosha.

Kufananidza iyo yekurapa yechipesa tester kune insulation kupokana uye kudzinga bvunzo dzazvino, iyo Dilelectric Kurasikirwa Factor Tgδ ine zvakakosha zvakanakira. Izvo hazvina chekuita neyekuedza voltage, tidzai saizi saizi uye zvimwe zvinhu, uye zviri nyore kusiyanisa shanduko yekuchinja kwemidziyo yemagetsi. Naizvozvo, iyo Dilelectric Kurasikirwa Factor Tgδ ndeimwe yemiedzo yakakosha yeiyo insulation bvunzo yemidziyo yemagetsi yakakwirira.

Iyo Dilelectric Kurasikirwa Factor Tgδ inogona kubatsira kuwana iyo inotevera insation triptcompers:

(1) kunyorova; (2) pinda iyo nzira yekufambisa; . .
