Matanho akajairwa ekuvandudza kugadzikana kwekupisa kweOPGW optical cables:
1. Shunt line nzira
Mutengo weOPGW optical cable wakakwira zvakanyanya, uye hazvisi zvehupfumi kungowedzera chikamu-chikamu kutakura pfupi-circuit ikozvino. Inowanzoshandiswa kumisa waya yekudzivirira mheni inofananidzwa neOPGW optical cable kuderedza ikozvino yeOPGW optical cable.
Kusarudzwa kweiyo shunt line kunofanirwa kusangana:
a. Iko kune yakaderera yakaderera impedance kuita iyo OPGW ikozvino inodonha pasi peinobvumirwa kukosha;
b. Inogona kupfuura yakakura zvakakwana ikozvino;
c. Paunenge uchisangana nezvinodiwa zvekudzivirira mheni, panofanira kunge paine yakakwana yekuchengetedza simba chinhu.
Inofanirawo kuonekwa kuti kunyange zvazvo kushorwa kwe shunt line kunogona kuderedzwa zvakanyanya, inductive reactance yayo inodonha zvishoma nezvishoma, saka basa re shunt line rinogumira; iyo shunt mutsara inogona kuve 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 kushandiswa kweOPGW tambo dzezvirevo zviviri
Kune mitsetse yakareba, nekuti iyo pfupi-yedunhu ikozvino pachikamu chekubuda cheiyo substation ndiyo yakakura, yakakura muchinjiko-chikamu OPGW optical cable inofanira kushandiswa; mutsara kubva kune substation inoshandisa diki chikamu OPGW optical cable. Mhando mbiri dzemitsara yeshunt dzinofanirwa kutariswa pakusarudza marudzi maviri eOPGW optical cables.
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 cheiyo pfupi-circuit ikozvino ipinde mu substation pasi pevhu, iyo inogona kuderedza zvakanyanya ikozvino yeOPGW optical. cable.
4. Parallel nzira yemitsara yekudzivirira mheni yakawanda
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 kwekushisa kwechipiri-giredhi OPGW tambo isingavimbike, chigadziro chepasi chechipiri base shongwe chinogona kubatanidzwa, zvichingodaro. Asi zvinofanirwa kucherechedzwa kuti relay zero sequence dziviriro inofanirwa kutariswa kana ichibatanidza shongwe dzakawanda.
