Fuse, tseem hu ua fuse, yog ib qho khoom siv tiv thaiv overcurrent dav siv hauv cov tshuab hluav taws xob faib hluav taws xob thiab tswj cov tshuab. Nws txoj haujlwm ua haujlwm yog siv cov thermal melting zog ntawm cov hlau; Lub sij hawm melting ntawm lub fuse muaj feem xyuam rau lub overcurrent muaj qhov sib txawv ntawm lub sij hawm txwv kev sib raug zoo, uas yog, qhov loj dua tam sim no, lub sij hawm luv luv, thiab qhov me me tam sim no, lub sij hawm fuses ntev dua.
Nyob rau hauv lub photovoltaic system, yog hais tias ib tug luv luv-circuit txhaum tshwm sim nyob rau hauv ib tug tej yam txoj hlua, xws li misconnection thaum lub sij hawm lub installation theem los yog lub zos txawv txawv thaiv los ntawm lwm yam yog vim li cas, overcurrent yuav tshwm sim. Tam sim no ntawm tag nrho cov hlua yuav ntws rov qab, ua rau cov hlua faulty muab lub zog rau qhov luv-circuit point. Qhov luv luv-circuit tam sim no, tsis muaj kev tiv thaiv kev tiv thaiv, yuav ua rau cov khoom siv thiab cov cables lossis cov khoom siv txuas nrog lawv raug hlawv, thiab tej zaum yuav ua rau hluav taws kub.
Nyob rau lub sijhawm no, yog tias muaj qhov tsim nyog DC fuse los tiv thaiv kab, piv txwv li, nyob rau hauv ib lub tswv yim uas ntau tshaj ob txoj hlua ntawm cov modules txuas nrog rau tib lub sijhawm, fuses raug ntsia ntawm ob qho kawg ntawm txhua txoj hlua photovoltaic. Txij li qhov luv luv tam sim no ntawm photovoltaic array ntau dua li tam sim no ntawm ib txoj hlua photovoltaic, lub photovoltaic system yuav puas. Cov fuses txuas nrog hauv series yog tshuab los cais cov faulty photovoltaic hlua, kom lub backlash tam sim no generated los ntawm qhov txhaum yuav nyob rau hauv lub rated tawg peev xwm ntawm lub photovoltaic fuse. Qhov no muab kev tiv thaiv kab thiab zam kev puas tsuaj rau lub photovoltaic system.
