Nei Waya yeBV Yakaputirwa nePVC Iri Mutsigiro weKubatana Kwakachengeteka kweTerminal

Chikamu 1: Chii chinonzi BV Waya? Tsananguro Yakajairika

Kuvaka kwakajairika:

• Kondakita: Copper yakasimba kana kuti yakasungirirwa (Kirasi 1 kana Kirasi 2, zvichienderana neIEC 60228)

• Kudzivirira: PVC mhando A, B, kana C (zvichienderana nekupisa uye mashandisirwo)

Zvikamu zvakajairika:0.5 mm² kusvika 10 mm² (yakanyanya kukosha kune Chivharo cheChiteshi kubatana mukati memapaneru ekudzora uye mabhokisi ejunction)

Kuyera kwevoltage:450/750 V (yakajairika) kana 300/500 V

Kuyera tembiricha:Kazhinji -15°C kusvika +70°C yePVC yakajairwa (mhando dzakakosha dziripo: -40°C kusvika +105°C)

Kusiyana newaya dzinochinjika (RVV, RV), waya yeBV ine waya inochinjikaPVC insulation yakakora, yakaoma uye yakaomauye kondakita yakasimba. Izvi zvinoita kuti ive yakakodzera kune:

• Waya dzakagadzika dzisingaperi mukati memapaneru emagetsi

• Kubatanidza waya dzemabhokisi ekuparadzira, maswitchboard, nemidziyo yemumba

• Kubatanidzwa kune screw-type uye spring-type terminal blocks uko ma solid kana stranded-clamped conductors anodiwa

  Chikamu 2: Nei PVC - Uye Sei Hunhu hwePVC Huchikosha

  Inenge 60% yekukundikana kwetambo kunokonzerwa nematambudziko ekudzivirira kupisa kunokonzerwa nekushandisa michina.chimiro chisina kunaka chePVC, kwete mhangura. Hezvino izvo vatengi vane hunyanzvi vanofanira kutarisa:

  2.1 Zviri mupurasitiki uye kutama
  PVC yemhando yepamusoro ine mapurasitiki akawandisa. Nekufamba kwenguva, mapurasitiki anotamira munzvimbo dzema terminal block (kunyanya PA66 kana PC), zvichikonzera kutsemuka kana kupfava kwe terminal block. Yueqing Gaopeng Electric yakaedza waya dzeBV kubva kuvatengesi vanopfuura makumi mana - tinogona kukuudzai:kutama hakuonekwe kusvika kwaparadza panel.

  2.2 Okisijeni indekisi (kunonoka kwemurazvo)
  PVC yakajairika ine chiyero cheokisijeni che26–30%. Waya yeBV yemhando yepamusoro inofanira kupfuura bvunzo yemoto yakatwasuka yeIEC 60332-1. Muongororo dzedu dzemurabhoritari, PVC isina kunaka inoramba ichitsva mushure mekunge murazvo wabviswa - njodzi yemoto yakananga.

  2.3 Kudzivirira kukwegura kwekupisa
  Sekureva kweIEC 60227, PVC insulation inofanira kutsungirira bvunzo yekukwegura kwemazuva manomwe pa80°C (yewaya yakayerwa pa70°C). PVC isina kusimba inooma uye inotsemuka mumazuva asingasviki matatu kana yave mumamiriro akafanana, zvichikonzera mashort circuits.

  2.4 Kuedza kukotama kwechando
  Kuti itumirwe kuEurope kana kuNorth America, waya yeBV inofanira kupfuura ne -15°C cold bend (kana -25°C kune mamwe magiredhi akakosha). PVC yakachipa inova yakaoma segirazi riri pasi pe 0°C - hazvigoneke kuisa zvakachengeteka munguva yechando kana mamiriro ekunze anotonhora.

  Chikamu 3: Mashandiro anoita BV Wire neTerminal Blocks - Maonero eUinjiniya

  Izvi zvakakosha kune chero mutengi anotenga waya nematerminal (kunyangwe kubva kuvatengesi vakasiyana). Waya yeBV isiriyo inogona kukonzera kutadza kushanda zvakanaka kwenzvimbo yeterminal block:

  3.1 Kuenderana kwekirasi yemutyairi

  • Ma terminal akawanda emhando ye screw (semuenzaniso, Gaopeng T-Series yedu) anogamuchira ese ari maviri ma solid (Class 1) uye stranded (Class 2).

  • Ma terminal emhando yechirimo anofarira Class 5 yakavharirwa kana inochinjika - asi waya dzakawanda dzeBV dzakasimba.

  • Muenzaniso wekusawirirana:Kushandisa BV yakasimba 4mm² muchikamu chesimbi chakagadzirirwa waya ine tambo dzakapfava kunoita kuti pave nekusunga uye kudhonzwa kusina kuvimbika.

  3.2 Kureba uye kunyatsoita basa rekubvisa
  Ukobvu hwePVC hwekuputira husiyana. Waya yeBV yakajairika zvichienderana neGB/T 5023.3 ine ukobvu hwakatsanangurwa hwekuputira (semuenzaniso, 0.8mm ye2.5mm²). Zvisinei, waya dzakawanda dzisingadhuri dzine kuputira kwakatetepa kana kusina kufanana. Mugumisiro: kungava kubvisa zvakanyanya (kuburitsa mhangura yakawandisa, kukonzera mapfupi) kana kubvisa zvishoma (PVC yakabatwa mukati me terminal, zvichikonzera kuramba kwakanyanya).

  3.3 Kondakita yakaita sedenderedzwa kana sechikamu
  Waya yeBV yemhando yepamusoro ine dhayamita yakatenderera zvechokwadi. BV yemhando yepamusoro inoshandisa mhangura yakapetwazve ine dhayamita isina kuenzana, iyo isingakwanise kugara zvakanaka mukati mejoko rekusunga re terminal block. Izvi zvinogadzirakuonana nevanhupachinzvimbo chekubatana kwemutsara - kuwedzera kwe300% mukudzivirira kusangana.
