style="text-indent:25px">太陽能電池組件接線盒：太陽能電池組件接線盒是介于太陽能電池組件構(gòu)成的太陽能電池方陣和太陽能充電控制裝置之間的連接器，是一門集電氣設(shè)計(jì)、機(jī)械設(shè)計(jì)與材料科學(xué)相結(jié)合的跨領(lǐng)域的綜合性設(shè)計(jì)。太陽能電池組件接線盒在太陽能組件的組成中非常重要，主要作用是將太陽能電池產(chǎn)生的電力與外部線路連接。接線盒通過硅膠與組件的背板粘在一起，組件內(nèi)的引出線通過接線盒內(nèi)的內(nèi)部線路連接在一起，內(nèi)部線路與外部線纜連接在一起，使組件與外部線纜導(dǎo)通。接線盒內(nèi)有二極管，保證組件在被擋光時(shí)能正常工作。太陽能電池組件接線盒的主要特性：1.外殼采用進(jìn)口高級(jí)原料生產(chǎn)，具有極高的抗老化，耐紫外線能力；2.適用于室外產(chǎn)時(shí)間惡劣環(huán)境條件下的使用，使用實(shí)效長達(dá)30年以上；3.根據(jù)需要可以任意內(nèi)置2～6個(gè)接線端子；4.所有的連接方式采用快接插入式方式連接。封膠密封小巧型接線箱優(yōu)點(diǎn)：由于灌膠密封，具有更好的防水、防塵性能。徐州防爆接線箱定做價(jià)格</p><p
