選擇正確的尺寸：當(dāng)然，選擇正確尺寸的防水盒首先是基于已有元器件的尺寸和設(shè)備要安放的位置來決定的。但是，我們也應(yīng)該考慮到是否在今后還會(huì)增加新的元器件，如果這樣，他的空間是否足夠。另外要注意的是，接線盒供應(yīng)商提供的參考尺寸是外形尺寸還是內(nèi)部尺寸?？砂惭b的空間通常比提供的內(nèi)部尺寸要小，這點(diǎn)也應(yīng)該留意到。南京防水接線箱定做pvc接線盒是電氣配管線路中管線長度。</p><div

開關(guān)盒.插座厎盒. 燈具盒都是這三種安裝時(shí)的終端厎盒，是安裝燈具. 開關(guān). 插座時(shí)安裝固定面板以及在盒內(nèi)接線用的。3. 接線盒和開關(guān)盒雖然屬于電氣安裝工程中的輔料，但在單獨(dú)的接線盒.開關(guān)盒安裝定額子目中，確是屬于未計(jì)價(jià)主材，需要輸入主材單價(jià)。4. pvc接線盒和開關(guān)盒無論是金屬盒還是PVC塑料盒，目前在安裝工程中普遍采用的為H86型盒，既盒面寬86mm，盒深有50mm. 70mm不等。5. 計(jì)算pvc接線盒時(shí)，燈頭盒. 插座盒. 開關(guān)盒是按照圖紙數(shù)量據(jù)實(shí)計(jì)算;分接線盒是按照管路分支或者返管時(shí)必須過渡，管路直線距離和彎頭數(shù)量超過規(guī)范規(guī)定的要求時(shí)必須增設(shè)接線盒，進(jìn)行據(jù)實(shí)計(jì)算的。這部分必須注意管路情況和管線及彎頭情況進(jìn)行分析計(jì)算，否則不是少算就會(huì)多算。防爆電機(jī)接線盒電纜密封結(jié)構(gòu)是保證接線盒防爆性能的重要組成部分。</p><div

style="text-indent:25px">接線盒各部分的功能：旁路二極管：主要作用防止組件的熱斑效應(yīng)。熱斑效應(yīng)：當(dāng)組件在使用時(shí)部分電池片被異物遮擋，將被當(dāng)作負(fù)載消耗其他有光照的太陽電池組件所產(chǎn)生的能量。被遮蔽的太陽電池片溫度會(huì)不斷升高此時(shí)會(huì)發(fā)熱，這就是熱斑效應(yīng)。如果有異物將電池片擋住造成了局部電池片不工作，局部電池片的溫度不斷上升、發(fā)熱較終會(huì)導(dǎo)致電池片燒壞。在太陽能電池板正常工作時(shí)旁路二極管不會(huì)起到作用，但當(dāng)遇到熱斑效應(yīng)時(shí)，旁路二極管會(huì)自動(dòng)越過該串電池串并與其它電池串相連繼續(xù)工作?，F(xiàn)在我們所使用的旁路二極管主要的作用也就是防止電池片燒掉。防反沖二極管：組件在沒有光照時(shí)防止蓄電池電流倒流。傳統(tǒng)型接線箱缺點(diǎn)：由于電器端子的存在，接線盒的體積較大、散熱性差。南京防水接線箱定做</p><p

style="text-indent:25px">接線盒的構(gòu)造：一般接線盒由盒蓋、盒體、接線端子、二極管、連接線、連接器幾大部分組成。接線盒各部分的功能：外殼要具有強(qiáng)烈的抗老化、耐紫外線能力;符合室外惡劣環(huán)境條件下的使用要求;自鎖功能使連接方式更加便捷、牢固;必須應(yīng)有防水密封設(shè)計(jì)、科學(xué)的防觸電絕緣保護(hù)，具有更好的安全性能;接線端子安裝要牢固，與匯流帶有良好的焊接性。二極管分為：旁路二極管和防反沖二極管。二極管的主要功能是單向?qū)üδ?。連接器、連接線：具有良好的絕緣性能，公母插頭帶有自鎖功能是太陽能電池板與電氣連接更便捷可靠。南京防水接線箱定做</p></p><br
