Nhasi, GL inotaura nezve akajairwa matanho ekugadzirisa kugadzikana kwekupisa kweOPGW tambo:
1: Shunt line nzira
Mutengo weOPGW tambo wakakwira zvakanyanya, uye hazvisi zvehupfumi kungo wedzera muchinjika-chikamu kuti utakure pfupi-yedunhu ikozvino.Inowanzo shandiswa kuseta waya yekudzivirira mheni inofananidzwa neOPGW tambo kuderedza ikozvino kweOPGW tambo.
Kusarudzwa kweiyo shunt line kunofanirwa kusangana:
a.Iko kune yakaderera yakaderera impedance kuita iyo OPGW ikozvino inodonha pasi peinobvumirwa kukosha;
b.Inogona kudarika yakakura zvakakwana ikozvino;
c.Paunenge uchisangana nezvinodiwa zvekudzivirira mheni, panofanirwa kuve neyakakwana simba rekuchengetedza chinhu.
Inofanirawo kuonekwa kuti kunyange zvazvo kushorwa kwe shunt line kunogona kuderedzwa zvakanyanya, inductive reactance yayo inodonha zvishoma nezvishoma, saka basa re shunt line rine imwe muganhu;iyo shunt mutsara inogona kunge yakavakirwa pane pfupi-yedunhu ikozvino mamiriro akatenderedza mutsara Sectional kusarudzwa, asi pakuchinja kweiyo shunt mutsara kushandura chikamu chemuenzaniso, kana zvikamu zviviri zvine musiyano mukuru, yakawanda ikozvino ichagoverwa kuOPGW. tambo, izvo zvichaita kuti ikozvino yeOPGW tambo iwedzere kamwe kamwe.Nokudaro, chikamu chemuchinjikwa che shunt line chinofanira kuongororwa kakawanda.
2: Kufanana kwekushandiswa kweOPGW tambo dzezvirevo zviviri
Kune mitsetse yakareba, nekuda kweiyo yakakura-pfupi-yedunhu ikozvino pane yekubuda chikamu chechiteshi, yakakura muchinjiko-chikamu OPGW tambo inofanira kushandiswa;mutsara uri kure nechiteshi unoshandisa tambo diki-chikamu OPGW tambo.Mhando mbiri dze shunt mitsara dzinofanirwa kutariswa pakusarudza maviri OPGW tambo.
3: Underground diversion nzira
Batanidza chigadziro chekugadzika cheiyo terminal tower uye gidhi rekugadzika reiyo substation ine akati wandei akatenderera simbi ane akakodzera machinjiro-zvikamu, kuitira kuti chikamu chenguva pfupi-yekutenderera ikozvino ipinde munzvimbo yepasi pevhu, iyo inogona kuderedza zvakanyanya ikozvino yeOPGW tambo. .
4: Parallel nzira yematanho ekudzivirira mheni akawanda edunhu
Batanidza zvigadziriso zvepasi zveakati wandei terminal shongwe kuti ipfupi-yedunhu ikozvino ipinde muchiteshi pamwe neakawanda-loop mheni yekudzivirira mutsara, kuitira kuti imwe-yedunhu ikozvino ideredze zvakanyanya.Kana kugadzikana kwekupisa kwechipiri-giredhi OPGW tambo isingavimbike, chigadziro chepasi chechipiri base tower chinogona kubatanidzwa, zvichingodaro.Asi zvinofanirwa kucherechedzwa kuti relay zero sequence dziviriro inofanirwa kutariswa kana ichibatanidza shongwe dzakawanda.
