保護(hù)作用 能根據(jù)設(shè)備的特點(diǎn),對設(shè)備、環(huán)境、以及人身實(shí)行自動(dòng)保護(hù),如電機(jī)的過熱保護(hù)、電網(wǎng)的短路保護(hù)、漏電保護(hù)等。
測量作用 利用儀表及與之相適應(yīng)的電器,對設(shè)備,電網(wǎng)或其它非電參數(shù)進(jìn)行測量,如電流、電壓、功率、轉(zhuǎn)速、溫度、濕度等。
調(diào)節(jié)作用 低壓電器可對一些電量和非電量進(jìn)行調(diào)整,以滿足用戶的要求,如柴油機(jī)油門的調(diào)整、房間溫濕度的調(diào)節(jié)、照度的自動(dòng)調(diào)節(jié)等。
指示作用 利用低壓電器的控制、保護(hù)等功能,檢測出設(shè)備運(yùn)行狀況與電氣電路工作情況,如絕緣監(jiān)測、保護(hù)掉牌指示等。
轉(zhuǎn)換作用 在用電設(shè)備之間轉(zhuǎn)換或?qū)Φ蛪弘娖鳌⒖刂齐娐贩謺r(shí)投入運(yùn)行,以實(shí)現(xiàn)功能切換,如勵(lì)磁裝置手動(dòng)與自動(dòng)的轉(zhuǎn)換,供電的市電與自備電的切換等
電磁式接觸器的工作原理如下:線圈通電后,在鐵芯中產(chǎn)生磁通及電磁吸力。此電磁吸力克服彈簧反力使得銜鐵吸合,帶動(dòng)觸點(diǎn)機(jī)構(gòu)動(dòng)作,常閉觸點(diǎn)打開,常開觸點(diǎn)閉合,互鎖或接通線路。線圈失電或線圈兩端電壓顯著降低時(shí),電磁吸力小于彈簧反力,使得銜鐵釋放,觸點(diǎn)機(jī)構(gòu)復(fù)位,斷開線路或解除互鎖。
