Fakalahi e fehokotakiʻanga ki he meʻangaue fakaʻuhila

Ki he ngaahi founga fakaʻuhila ki he malú, ʻe lava ke fakafaʻahinga ʻa e ngaahi fehokotakiʻanga fakauaea ki he ngaahi fehokotakiʻanga fakaʻuhila mei tuʻa (ʻi he feituʻu ʻoku fakahu ai ʻe he ngaahi uaea ʻi tuʻa ʻa e ngaahi meʻa ʻoku malu) mo e ngaahi fehokotakiʻanga fakaʻuhila fakalotofonua (ʻi he vahaʻa ʻo e ngaahi konga ʻi loto). Ongo faʻahinga fehokotakiʻanga fakatouʻosi angamaheni ʻaki hono fakaʻaongaʻi e ngaahi uaea ʻo e kopa ki honau ivi fakamisini maʻolunga, fakafepaki maʻulalo, mo e conductivity maʻolunga ange.

Ngaahi fehokotakiʻanga fakaʻuhila ʻi tuʻa:

ʻI he taimi ʻoku fai ai ha ngaahi fehokotakiʻanga mei tuʻa, ʻOku totonu ke fakahu ʻe he ngaahi uaea ʻa e ngaahi meʻa ʻoku malu ʻi ha gland keipolo. Ko e fehokotaki ʻi he vahaʻa ʻo e keipolo mo e connectors ʻi loto (feituʻu) Kuo pau ke fakapapauʻi ʻoku malu ʻa e taʻau ʻo e ʻuhila, mo e ngaahi feituʻu ʻoku ʻi ai e sectional ʻi he founga totonu.

Ngaahi fehokotakiʻanga fakaʻuhila fakalotofonua:

ʻI loto, ʻOku totonu ke fokotuʻutuʻu mo fokotuʻutuʻu ʻa e fakauaea kotoa pe ki he fakaʻehiʻehi mei he mafana ʻo e ʻea mo e ngaahi konga ʻoku hiki. Kapau ʻoku loloa ʻa e uaea, kuo pau ke maluʻi kinautolu ʻi he ngaahi meʻa ʻoku feʻunga. ʻIkai ngata ai, ʻOku ʻikai totonu ke kau ʻi he ngaahi fehokotakiʻanga ʻi loto ʻa e ngaahi hokotanga hui.

Lolotonga ngāue ʻakí, ngaahi fehokotaki kotoa ʻi he uaea mo e feituʻu (hange ko conductive polota) kuo pau ke malu mo tauʻataina mei he looseness, fakaʻehiʻehi mei hono motuhi. ʻE lava ke fakaʻaongaʻi ha ngaahi founga kehekehe ke aʻusia ai ʻeni:

1. Fehokotakiʻanga ʻo e foʻi nati lahi:

Ki he foʻi nati lahi, ʻOku totonu ke maʻu maʻu pe ʻa e tefitoʻi uaea ʻe ha lug (ko ha “O” foʻi mama ʻoku ʻikai ke ʻi, ʻikai ko ha “0” foʻi mama) ʻi he malaʻe vakapuna, fakaʻaongaʻi ha foʻi nati. ʻOku fie maʻu ʻa e ngaahi fehokotakiʻanga momoko ki he uaea tefito mo e lug. Pe, ʻe lava ke nonoʻo ʻa e tefitoʻi uaea, tinned, pea kuo fakatokalelei ki ha ola tatau.
ʻI he foʻi nati lahi, ʻOku mahuʻinga ke conductive e polota (feituʻu) ʻOku ngaohi ʻaki e kopa, tautautefito ʻi he tuʻunga maʻolunga. Ko e meʻa tatau pe, ʻOku totonu ke fakaʻaongaʻi ʻa e kopa fufulu ha ngaahi, mo e ngaahi meʻafua ʻo e kau ʻAnitai-loosening hange ko e ukamea compressing ʻoku totonu ke fokotuʻu ʻa e kopa pe tatau. Kuo pau ke ʻoua naʻa vilo ʻa e conductive ʻi he lolotonga hono fakafehokotaki ʻo e uaea.

ʻOku faʻa fakahaaʻi ʻe he ngaahi founga lalahi ʻa hono fakaʻaongaʻi ʻo e ukamea fufulu ha ngaahi mo e foʻu ʻi he ngaahi fehokotakiʻanga foʻi nati lahi, ʻa ia te ne lava ʻo fakatupulaki ʻa e fakafepaki ki he fetuʻ, tautautefito ki he ʻau maʻolunga, iku ki he fuʻu fakamafana mo e maumau ʻe ala hoko ki he ʻaofi maluʻi mei – ko ha fakatuʻutamaki mahuʻinga.

2. Clamp lahi fehokotakiʻanga:

Ki he ngaahi fehokotakiʻanga ʻo e Clamp lahi, ʻo hangē ko ʻene hā ʻi he Konga 1.19, ʻOku fakaʻaongaʻi ha faʻunga ʻoku feʻunga mo e ngaahi tukunga lolotonga. Kuo pau ke kau ʻi he sikalu pe polota ki he peleti lahi ʻa e faʻahitaʻu failau fufulu ha ngaahi ke taʻofi loosening – ko ha meʻafua mahuʻinga ʻo e malu.
ʻI he faʻahinga fehokotaki peheé, ʻa e feituʻu fetuʻutaki mo e uho keipolo, ʻi he taimi ʻoku fuopotopoto ai, totonu ke ʻi ai ha curvature feʻunga, fakapapauʻi ha feituʻu fetuʻutaki feʻunga ke fakasiʻisiʻi ai e fakafepaki mo e fakamafana.

3. Ngaahi founga fakafehokotaki kehe:

Makehe mei he ngaahi, ʻe lava ke fakaʻaongaʻi ʻa e ngaahi founga tatau hange ko e plug-in pe soldered ʻi he meʻangaue fakaʻuhila ʻoku malu.
Ki he plug-in ngaahi fehokotakiʻangá, fie maʻu ha faʻunga ʻoku lokaʻi, faʻa fakaʻaongaʻi ki he fakauaea ʻi loto. ʻOku fakapapauʻi ʻe heʻene founga lokaʻi ʻoku kei malu pe ʻa e palaki lolotonga e tafa.

ʻI he taimi ʻoku fakaʻaongaʻi ai ʻa e ngaahi konga ʻoku ʻikai ke ʻi ai ha ngaahi fehokotakiʻanga ʻi he plug, ʻOku fie maʻu ʻa e ngaahi founga ʻoku ne fakafepakiʻi lelei ʻa e loosening. Kuo pau ke taʻofi ʻe he konga ʻoku ʻikai ke ʻi ai ha uaea.

ʻI he ngaahi fehokotakiʻanga soldered, ʻOku angamaheni ʻaki hono fakaʻaongaʻi ʻa e ngeEesi soldering ki he fakauaea ʻi loto. ʻOku totonu ke maʻu ʻa e uaea ʻi he ngaahi poini solder ke fakaʻehiʻehi mei he faingataʻaʻia ʻoku ʻikai mahuʻinga.

Ko e tefitoʻi hohaʻa ʻi he ngaahi fehokotakiʻanga soldered ko e fakaʻehiʻehi mei “momoko solder” ngaahi hokotanga hui, ʻa ia te ne lava ʻo fakatupu ha ngaahi meʻa ke fakalele ʻaki mo katakiʻingataʻa fakamafana ʻi he fuoloa ʻo e fakaivia.

Makehe mei he ngaahi, ʻe lava ke fakaʻaongaʻi ha ngaahi founga fakafehokotaki tatau mo falalaʻanga. All these measures aim to ensure reliable electrical contact at the connection points. High contact resistance can lead to increased temperatures, potentially creating a “dangerous mafana ʻo e ʻea” maʻuʻanga ignition. Loose connections, leading to wire disengagement and potential electrical discharges, are absolutely unacceptable.
