Impamvu insinga za BV zifungishijwe na PVC ari inkingi ikomeye yo guhuza ibyuma mu buryo bwizewe

Igice cya 1: Insinga ya BV ni iki? Ibisobanuro bisanzwe

Imiterere isanzwe:

• Kondukteri: Umuringa ukomeye cyangwa upfundikiye (Icyiciro cya 1 cyangwa Icyiciro cya 2, nk'uko IEC 60228 ibivuga)

• Ubwikorezi: PVC yo mu bwoko bwa A, B, cyangwa C (biterwa n'ubushyuhe n'ikoreshwa)

Ibice bihuriweho:0.5 mm² kugeza kuri 10 mm² (bikenewe cyane kuri Ihuriro ry'aho batembera imiyoboro iri imbere mu matsinda yo kugenzura no mu dusanduku tw’aho gushyira ibintu (communications pan)

Igipimo cy'amashanyarazi:450/750 V (isanzwe cyane) cyangwa 300/500 V

Igipimo cy'ubushyuhe:Ubusanzwe -15°C kugeza +70°C kuri PVC isanzwe (ingero zihariye zirahari: -40°C kugeza +105°C)

Bitandukanye n'insinga zoroshye (RVV, RV), insinga za BV zifiteubushyuhe bwa PVC bukomeye kandi bukomeyen'icyuma gikonjesha. Ibi bituma kiba cyiza kuri:

• Insinga zihoraho zihamye imbere mu byuma by'amashanyarazi

• Insinga z'ibikoresho byo mu rugo, amasanduku yo gukwirakwizamo ibikoresho, n'ibikoresho byo mu rugo bidahinduka

• Guhuza na screw-type na spring-type terminal blocks aho ibyuma bikomeye cyangwa bifite stranded-clamped bikenewe

  Igice cya 2: Impamvu PVC - n'impamvu Ubwiza bwa PVC ari ingenzi

  Hafi 60% by'ihungabana ry'insinga riterwa n'ibibazo byo gukingira insinga mu by'ukuri biterwa n'ukoifumbire mbi ya PVC, ntabwo ari umuringa. Dore ibyo abaguzi b'inzobere bagomba kugenzura:

  2.1 Ibikubiye muri pulasitiki n'ibyimuka
  PVC yujuje ubuziranenge ikubiyemo pulasitiki nyinshi. Uko igihe kigenda gihita, pulasitiki yimukira mu mazu y’ibikoresho bya terminal block (cyane cyane PA66 cyangwa PC), bigatuma terminal block icika cyangwa igacika. Yueqing Gaopeng Electric yagerageje insinga za BV ziturutse ku batanga serivisi barenga 40 - turababwira:kwimuka ntibigaragara kugeza igihe byasenye agasanduku.

  2.2 Igipimo cya ogisijeni (ubushyuhe bw'umuriro)
  PVC isanzwe ifite igipimo cya ogisijeni kiri hagati ya 26–30%. Insinga ya BV nziza igomba gutsinda ikizamini cya IEC 60332-1 cy'umuriro uhagaze. Mu bizamini byacu bya laboratwari, PVC mbi ikomeza kwaka nyuma y'uko umuriro ukuweho - ibyago by'umuriro utaziguye.

  2.3 Ubudahangarwa ku busaza bw'ubushyuhe
  Dukurikije IEC 60227, PVC irinda ubushyuhe igomba kwihanganira ikizamini cy’iminsi 7 cyo gusaza kuri 80°C (ku nsinga ifite ubushyuhe bwa 70°C). PVC idakora neza irakomera kandi igacika mu minsi itarenze 3 iyo imeze kimwe, bigatuma habaho imiyoboro migufi.

  2.4 Ikizamini cyo kugonda mu gihe cy'ubukonje
  Kugira ngo yoherezwe mu Burayi cyangwa muri Amerika ya Ruguru, insinga za BV zigomba kunyura kuri -15°C ubukonje bugana (cyangwa -25°C ku bipimo byihariye). PVC ihendutse iracika intege nk'ikirahure kiri munsi ya 0°C - ntibishoboka kuyishyiraho neza mu gihe cy'itumba cyangwa mu bihe bikonje.

  Igice cya 3: Uburyo BV Wire ikorana na Terminal Blocks - Ishusho y'Ubwubatsi

  Ibi ni ingenzi ku muguzi wese uguze insinga n'imiyoboro (ndetse no ku batanga serivisi zitandukanye). Insinga za BV zitari zo zishobora gutuma terminal block field inanirwa:

  3.1 Guhuza icyiciro cy'umuyobozi

  • Ibikoresho byinshi byo mu bwoko bwa screw (urugero, Gaopeng T-Series) byakira ibyuma bikomeye (Class 1) n'ibidakora (Class 2).

  • Ibikoresho byo mu bwoko bwa Spring bikunda Class 5 yazimiye cyangwa yoroshye kuyikoresha - ariko insinga nyinshi za BV zirakomeye.

  • Urugero rwo kudahuza:Gukoresha BV 4mm² ikomeye mu gice cy’icyuma gifunga insinga cyagenewe insinga nziza bituma umuntu afunga neza kandi agakuramo.

  3.2 Uburebure n'ubuziranenge bwo gukata
  Ubunini bw'insinga za PVC buratandukanye. Insinga zisanzwe za BV nk'uko GB/T 5023.3 ibivuga, zifite ubunini bwa insinga zisanzwe (urugero: 0.8mm kuri 2.5mm²). Ariko, insinga nyinshi zihendutse zifite insinga zoroshye cyangwa zitangana. Ibisubizo: haba gukuraho cyane (gushyiramo umuringa mwinshi cyane, bigatera imiyoboro migufi) cyangwa gukuraho hasi (PVC yafashwe imbere mu gice cy'insinga, bigatera uburinzi bwinshi).

  3.3 Umuyoboro w'amashanyarazi umeze nk'uruziga ugereranije n'urwego rw'umuyoboro w'amashanyarazi
  Insinga ya BV nziza ifite umuyoboro w’uruziga koko. BV mbi ikoresha umuringa usubiwemo ufite umurambararo utaringaniye, udashobora kwinjira neza mu mwanya wo gufunga wa terminal block. Ibi bitumaaho umuntu ashobora kuvugana n'umuntuaho gukora ku murongo - kwiyongera kwa 300% mu kudakora ku murongo.
