Kia Haumaru me ngā Taputapu VDE

Te Whakapōkai i ngā Taputapu VDE mō te Haumaru Hiko

Ko ngā taputapu VDE (Verband der Elektrotechnik) he kāri pakaru hei haumā. Hoahoa hei whakaukete i ngā hinganga hiko ina mahi ana i ngā wiri katoa e 1,000 volts neke atu rānei. Kua whakamātua tātari tōtika mō te tihomana IEC 60900 e whai ana i te whakamātau i te kaha o te whakakaha o ēnei taputapu kia rua te rahi ake i ā rātou hiko mahi, me te whakamātau i te kaha ki te karo i te wera. Ka taea e koutou te kite i te tohu VDE kikorangi ki te whakaaetanga ki ā katoa o tātou taputapu whakakaha, e whakaatu ana kei te rite ki ngā tihomana VDE me te 1000V rite | tihomana haumā, ka tūhono hoki ki te whakapūmau i te whakakaha mena ko te kawhe he whara, he wera rānei te āhua o te wā i te wā roa.

Ko ngā taputapu tohu VDE e wehe ai i ngā ara hiko ki ngā arai kore-metara me ngā tōwhe whakakaha. Ko te whakamātau tuatoru e whakamātua i te whakakaha e 100 MΩ neke ake—mea matua hei here i ngā hiko mate ki te uaua ki ngā wāhi kua whakauru hiko. Hei whakarārangi, ko OSHA 1910.137 e here ana i ngā taputapu whakakaha mō te katoa o ngā mahi e uru mai ana ki ngā kawhe e 50 volts ake rānei te hiko.

Ko te whakamahi i ngā taputapu VDE e iti iho te tūpono o ngā pakanga arca ki te 89% i ngā taiao taura itiwha ina whakaritea ki ngā taputapu kāore i te whakamataku. Ko ngā tākohanga i ngā tāone nui e whai mōhio ana ki ēnei taputapu kāore i te tautohetohe i runga i te NFPA 70E Tuhinga 130, engari ko te tuakiri tuatahi hei whakamaru i te utu $2.2 piriona i te tau mō ngā whara e puta ana i ngā mahi e pa ana ki te hiko.

Ngā Taputapu VDE me ngā Tikanga Whakamana Matua

He aha te whakamana a VDE

Ko te whakamana a VDE e whakapau ana i te tautohetohe kia ū ki te tihanga IEC 60900 e whakapono ana i te whakamaru tōtika mai i te patunga hiko ki runga ake i te 1,000 volts A.C me te 1,500 volts D.C. Ko tēnei whakamana e whakapono ana i te hiko, te hinonga me te patunga wera kia pūmau ai te whakapono o te taputapu i muri i te noho ki te 10kV te ōwe o te whakamataku me te 30N&midot;m te tōwai. Ko te tautohetohe e whakapono ana i te kaha o te wehe, ngā arai kāore he hihiani, me te kore e kitea ngā paraihe kauta ki ngā wāhi e mahi ana - katoa he mea nui hei whakatika i ngā pāpaku autō, pērā i te whakatika i ngā panu autō, pērā i te whakatika rānei i ngā ara hiko.

Ngā Tikanga Whakamātai Whakamau: Aha, Kaimoana me te Pakanga

Whakamātaiahia ngā whakamau VDE ngā whakapai kore e toru ngā tikanga matua:

1. AC Aha Whakapai : Ko ngā taputapu e 10kV AC mā te 3 meneti kia kaua e piki haere i te wāhi pāpaku.
2. Kaimoana Pakanga : Ko ngā taha e pakaru ana i te 70 ° C (158 ° F) mā te 168 haora kia whakamātau i te pūmahara o ngā taputapu.
3. Māmā Kāpua : Whakaurua ki ngā keke -25 ° C (-13 ° F) kia whakapono kia kaua e pakaru i te wa e whakakaha ana.
   I tētahi whakamātau ā-rohe i te tau 2023 i kitea ngā taputapu kāore i te whakamātai whakamau 47% te rahinga ake i ngā kape tāpiri e whai tikanga ana i muri i te 18 marama o te whakamahinga ia rā, e toa ana i te uara whakakaha ake o te kaupapa.

Te whakamana i ngā Tohu Haumaru VDE

Ko ngā taputapu VDE tūturu he whakaahua hōu huingaite me ngā kōtaha pūāhua panonihanga e āhua kitea ana ki te pātengia VDE. Ko ngā taputapu parurenga kaua ko te iti:

• Whakaahua hōu ā-hāngū e rereke ana te tae
• Kōtaha ID motuhake mō te taputapu e ōrite ana ki ngā tuhinga a te kaihanga
• Tuhinga whakamana mai i te wāhanga tātari tuatoru
  He pūrongo a te Tōpiko Ahumoni Haumaru Hiko 22% o ngā taputapu "VDE-whakamana" kua hokona ki te ipurangi i te tau 2024 kāore i ngā tohu whakamana e kitea ana - he rongoa whakatūpato mō ngā kaiwhakamahi pūkenga e rapu ana i ngā taputapu. Me āhua tautohu ngā whakaaetanga ki te rēkōtia VDE māmā i mua i te whakamahinga.
