Mheni uye Overvoltage Dziviriro yeMain Power
GPAS yeLV Ground Inogoneka Overvoltage Attack
GPAS chishandiso chinoshanda uye chinoshanda chekudzivirira mheni chinosanganisa pasi chinogona kudzvinyirira kudzvinyirira uye kukanganisa arc kudzivirira. Inogona kuderedza zvakanyanya kukuvadzwa uye kukanganisa kwepasi kunogona kupikisa uye kutadza kwearc pamidziyo kana yaiswa munjodzi yemheni.
Kana kurova kwemheni kwakananga kunoitika, tsvimbo yemheni kana network yekudzivirira mheni yakabatana, uye mheni yakasimba ikozvino inoyerera ichipinda mugidhi revhu. Kana mitsetse yakakwira-voltage ikasangana nemheni yakawandisa, mheni inoyerera ichipinda mugedhi revhu kuburikidza nemheni zvinosunga. Kana midziyo yakasimba yekupindira yakaita semichina yewelding inoshanda, iyo yakasimba yekupindira ikozvino inogadzirwa navo ichayerera ichipinda mugidhi revhu. Yakasimba yekugadzika ikozvino inogona kukonzera kurasikirwa kwedata, kukanganiswa kwemidziyo, kudonha kwemidziyo, kukuvara kwekudzivirira kana kupisa mune yakaderera-voltage magetsi emagetsi masisitimu.
GPAS ine kuvimbika kwepamusoro uye ipfupi nguva yekuita, iyo inogona kunyatsoparadzanisa yakakwirira-frequency mafungu emheni, kudzivirira mheni kubva kune inodzivirira ivhu network kubva kune mheni kudzivirira grounding network, uye zvinobudirira kudzivirira kuitika kwenjodzi dzekugadzira njodzi dzakadai semoto uye kuputika.
LOPS yeMV Bhazi Overvoltage Dziviriro
Iyo LOPS yakaderera-voltage bhazi overvoltage suppression mudziyo yakabatana zvakananga mukuenderana nebhazi, ichishandisa matekinoroji akadai seanokurumidza controller, high-energy nonlinear resistors, overvoltage peak interceptors, uye counterattack kudzvinyirira. Yakaverengerwa nesainzi uye yakagadzirwa zvakanaka. LOPS inoshandisa zvizere yakanakisa volt ampere hunhu, hombe yekupisa simba, uye nekukurumidza kupindura kumhanya kwe overvoltage interceptors, nonlinear resistors, uye counterattack kudzvinyirira michina. Kazhinji, kuseta kukosha kwekuita kweLOPS pa1.2 nguva iyo system phase voltage (customizable in special kesi) inogona kuwana mhedzisiro yakanaka panguva yekushanda.
LOPS yakabatana zvakananga mukuenderana nebhasibar, ichishandisa matekinoroji akadai seanokurumidza controllers, yakakwirira-simba nonlinear resistors, overvoltage peak interceptors, uye counterattack kudzvinyirira. Yakaverengerwa nesainzi uye yakagadzirwa zvakanaka. LOPS inotsiva kushomeka senge SPD, yakasanganiswa overvoltage kudzivirira, uye kuramba capacitance absorption, kugadzirisa zvachose dambudziko rekuwandisa pane yepakati voltage main busbar.
LOPT yeMV Overhead Lines Overvoltage Dziviriro
35kV ~ 6kV mitsetse yekumusoro inowanzoisa ZnO zvinosunga. Pane zvikanganiso zvinotungamira mukugumburwa, mutsara watyoka uye wakasviba-kunze.
Kudzivirirwa Kwemheni Kutsva kweMutsetse weKutakurisa Kwepamusoro (LOPT) Yakavakirwa padhuze necathode effect, yakawanda-level pfupi gap arc kuvhuvhuta nekudzima tekinoroji, ichipaza nepakati pemagetsi anonzwa hunhu hweZnO vanosunga, inoshandisa musimboti weakawanda chamber gap arc kuvhuvhuta nekudzima, yakakosha dhizaini yekurebesa nekurebesa chinangwa chearc. kudzima.
LOPT ine zvakanakira senge yakachengeteka, yakavimbika, yakarebesa hupenyu, uye diki kugadzirisa. Inogona kukurumidza kuburitsa simba remheni, kudzivirira kuputika kwemheni uye kugumburwa, uye ine kuchengetedza yemahara uye yekuzvichenesa mabasa.
