◆工控產(chǎn)品芯片封裝的內(nèi)部連接
◆工控產(chǎn)品封裝引腳與PCB的連接。典型連接器IC插座。
◆印制電路與導(dǎo)線或印制板的連接。典型連接器為印制電路連接器。
◆底板與底板的連接。典型連接器為機(jī)柜式連接器。
◆設(shè)備與設(shè)備之間的連接。典型產(chǎn)品為圓形連接器。
◆接觸電阻高質(zhì)量的電連接器應(yīng)當(dāng)具有低而穩(wěn)定的接觸電阻。連接器的接觸電阻從幾毫歐到數(shù)十毫歐不等。
◆絕緣電阻衡量電連接器接觸件之間和接觸件與外殼之間絕緣性能的指標(biāo)，其數(shù)量級(jí)為數(shù)百兆歐至數(shù)千兆歐不等。
◆抗電強(qiáng)度或稱耐電壓、介質(zhì)耐壓，是表征連接器接觸件之間或接觸件與外殼之間耐受額定試驗(yàn)電壓的能力。

組合式電流電壓互感器。組合式互感器由電流互感器和電壓互感器組合而成，多安裝于高壓計(jì)量箱、柜，用作計(jì)量電能或用作用電設(shè)備繼電保護(hù)裝置的電源。組合式電流電壓互感器是將兩臺(tái)或三臺(tái)電流互感器的一次、二次繞組及鐵心和電壓互感器的一、二次繞組及鐵心，固定在鋼體構(gòu)架上，浸入裝有變壓器油的箱體內(nèi)，其一、二次繞組出線均引出，接在箱體外的高、低壓瓷瓶上，形成絕緣、封閉的整體。一次側(cè)與供電線路連接，二次側(cè)與計(jì)量裝置或繼電保護(hù)裝置連接。根據(jù)不同的需要，組合式電流電壓互感器分為V/V接線和Y/Y接線兩種，以計(jì)量三相負(fù)荷平衡或不平衡時(shí)的電能。
電力系統(tǒng)為了傳輸電能，往往采用交流電壓、大電流回路把電力送往用戶，無(wú)法用儀表進(jìn)行直接測(cè)量。互感器的作用，就是將交流電壓和大電流按比例降到可以用儀表直接測(cè)量的數(shù)值，便于儀表直接測(cè)量，同時(shí)為繼電保護(hù)和自動(dòng)裝置提供電源。電力系統(tǒng)用互感器是將電網(wǎng)高電壓、大電流的信息傳遞到低電壓、小電流二次側(cè)的計(jì)量、測(cè)量?jī)x表及繼電保護(hù)、自動(dòng)裝置的一種特殊變壓器，是一次系統(tǒng)和二次系統(tǒng)的聯(lián)絡(luò)元件，其一次繞組接入電網(wǎng)，二次繞組分別與測(cè)量?jī)x表、保護(hù)裝置等互相連接。互感器與測(cè)量?jī)x表和計(jì)量裝置配合，可以測(cè)量一次系統(tǒng)的電壓、電流和電能；與繼電保護(hù)和自動(dòng)裝置配合，可以構(gòu)成對(duì)電網(wǎng)各種故障的電氣保護(hù)和自動(dòng)控制。互感器性能的好壞，直接影響到電力系統(tǒng)測(cè)量、計(jì)量的準(zhǔn)確性和繼電器保護(hù)裝置動(dòng)作的可靠性。
