中文拼音 [bìkāichùtóu]
閉開觸頭
英文
make-and-break contact-
2 miniaturized vacuum arc quenching chamber which is with cucr25 contact material, cup shape and longitudinal magnetic field contact structure, intensive interrupting ability is used. vacuum arc quenching chamber is laid in a sealed insulating cylinder, which significantly improve the ability of enduring environment and phase - phase insulation character
2 、設計了採用cucr25觸頭材料、杯狀縱磁場觸頭結構、開斷能力很強的小型化真空滅弧室;真空滅弧室布置在封閉的絕緣筒內,提高了環境耐受能力,同時使相間絕緣性能顯著提高。The current transformer is fully enclosed structure. the terminal p1 of the primary winding is as the static contact of the switch cabinet and placed inside the epoxy - resin insulation cavity
本型電流互感器為全封閉結構,其一次繞組的p1端子,直接作為開關櫃中的靜觸頭被設置在環氧澆注的絕緣空腔內。When the contacts are connected into direct circuit, we can judge whether the contacts are open or not through analyzing the voltage instantaneous values across the two contacts
當有觸點電器的觸頭接入直流電路中時,可通過觸頭兩端電壓瞬時值來判斷它是打開還是閉合。Whereas if the contacts are in series with the alternating circuit, due to the passing zero property of voltage, we must evaluate the condition of contacts according to voltage value
但當觸頭接入交流電路中時,由於電壓有過零的特徵,所以要根據電壓有效值來判斷觸頭是打開還是閉合。分享友人
