Mekanizmo wa Kusimamia CT40 Spring

Mechanizmo wa CT40 wa spring operated ni ni kifaa cha kuhamisha nguvu kilicho undwa kusoma tu kwa ajili ya switchgear za kiwango cha medium na high voltage (kama vile vacuum circuit breakers, SF6 load switches) za 10kV-40.5kV. Kwa nishati ya storage ya spring kama chanzo muhimu cha nguvu, imekuwa kifaa muhimu katika mifumo ya distribution ya medium voltage, industrial substations, na mitandao ya distribution ya nje kutokana na ufanisi wake wa mekaniakia, njia rahisi ya kufanya kazi, na uwezo mkubwa wa kuadabisha. Inatoa usaidizi wa nguvu usemi na imara kwa matumizi ya opening na closing ya switch, husikii hali nzuri na upatikanaji mzuri wa mifumo ya umeme.
1、 Sifa muhimu ya kazi: Logic inayofanyika kwa urahisi iliyodhibitiwa na nishati ya storage ya spring
Sifa muhimu ya mechanizmo wa CT40 spring operated ni mzunguko wa transmission ya mekaniakia wa "storage ya nishati release", ambayo hutumia nguvu ya potential ya elastic iliyostorekwa katika spring ili kudrive switching device kupata matumizi ya opening na closing. Mzunguko kamili unafanikiwa kama ifuatavyo:
1. Hatua ya storage ya nishati
Storage ya nishati ya umeme: Mara nyingi, aina ya umeme inapendeleka. Motori (AC220V/DC220V, nguvu ≤ 150W) hutumia seti ya reduction gear kufanya kazi na kukidhi energy storage shaft kurudi. Energy storage shaft hutumia mechanism ya cam ili kudhibiti closing spring. Wakati spring imebadilika hadi stroke yenye ukosefu (inayotumaini hatua ya completion ya storage ya nishati), energy storage pawl hutumia na kuhakikisha ratchet wheel. Pia, switch ya stroke huamsha motori kutoka power, na hatua ya storage ya nishati hukimaliza (muda ≤ 15s), na mechanism huenda katika hali ya waiting closing.
Storage ya nishati ya mkono: Kama njia ya backup ya dharura, wakati motori inakuwa na tatizo au hakuna power supply, energy storage shaft inaweza kurudi kwa kutumia manual rocker arm, manually kudhibiti closing spring mpaka pawl ikahakikishwa. Rocker arm inahitaji kurudi ≤ 40 turns (na mwendo wa 30r/min) kwa muda mzima ili kuhakikisha storage ya nishati ya normal katika hali za dharura.
2. Matumizi ya opening na closing actions
Closing operation: Baada ya kupokea ishara ya closing, closing electromagnetic iron hupewa nguvu ili kudrive release mechanism kurelease energy storage pawl. Closing spring mara moja hutumia nishati ya potential ya elastic, ambayo hutumia connecting rod transmission mechanism ili kudrive moving contact ya switchgear kupitia kwa haraka kufunga, kupimisha process ya closing; Pia, closing action hutumia kushuka opening spring, kutengeneza nishati mapema kwa matumizi ya baadaye ya opening operations.
Opening operation: Wakati unapokea ishara ya opening (au kwa mkono kuleta opening handle), opening electromagnet (au component ya mechanical release) hujihidi, opening lock huruhusiwa, opening spring hutumia nishati, na transmission mechanism huchukuliwa kudisconnect moving contact kwa haraka, kutembelea circuit (opening time ≤ 25ms, inaweza kudisconnect kwa haraka current ya fault, kupunguza athari ya majanga).

Mipangilio muhimu ya structure: sifa za kuaminika zinazokubalika kwenye scenarios za medium voltage
1. Architecture ya mekaniakia ya juu ya stability
Modular component design: Energy storage component (spring, gear set), transmission component (connecting rod, cam), na control component (electromagnet, travel switch) zimegawanyika kwa moduli madaraka, vilivyokidhiwa kwa precision shaft sleeves na matching accuracy ya 0.05mm, kupunguza loss ya friction ya mekaniakia na kuongeza life ya mekaniakia (≥ 10000 opening na closing operations).
Chaguo la materiali ya juu ya strength: Closing spring imeundwa kwa steel ya spring alloy 60Si2MnA, ambayo imefanya isothermal quenching na tempering heat treatment, na tensile strength ≥ 1800MPa na hakuna permanent deformation baada ya storage ya nishati kwa muda mrefu; Transmission connecting rod na energy storage shaft zimeundwa kwa Q235B cold-rolled steel plate, na surface galvanized (thickness ya zinc layer ≥ 8 μ m) na corrosion resistance ya salt spray ya 480 hours, inayofaa kwa mazingira ya distribution ya machafu na dust.
2. Usaidizi wa kufanya kazi na monitoring ya status
Visual status indication: Mechanism housing imeundwa na mechanical pointers kwa "energy storage status" (red - not stored/green - stored) na "opening/closing status" (blue - open/yellow - closed), yanayoweza kuhakikisha hali ya sasa ya equipment bila kugawa, kusaidia utafiti na troubleshooting ya on-site.
Compatible installation interface: Chini imeundwa na standardized installation holes (hole spacing suitable for universal installation dimensions of 10kV-35kV circuit breakers), ambazo hazitahitaji brackets customized na zinaweza kufixed kwa 4 M12 bolts, kupunguza muda wa installation hadi chini ya 30 minutes; Electrical wiring imeundwa na plug-in terminals, na connection ya opening na closing electromagnet na travel switch haipaswi kuwa na welding, inaongeza efficiency ya on-site debugging.
