Mwendo wa Msingi wa Mzunguko wa Majukumu ya Umeme kwa Usalama wa Kupunguza Ugawaji
Ⅰ. Mazingira ya Matatizo
Kama kifaa muhimu katika mitandao ya umeme wa miji, vituo vya ring main (RMUs) vinatumika sana katika maeneo ya makazi, viwanda, na majengo ya umma kutokana na ujumbe wao mdogo, gharama chache, na uhakika mkubwa. Hata hivyo, matatizo ya vifaa vya ndani au arc faults zinaweza kuboresha gasi ya joto kwa nguvu nyingi, kusababisha mvuto wa sanduku ambayo inaweza kuongeza hatari kwa watu na vifaa. Ingawa mifano ya kufunga yenyeleweka yanaweza kupata integriti ya insulation, hazitoshi kutekeleza mzunguko wa pressure wa haraka. Mechanism ya kurekebisha pressure ya kina ya kina ni lazima mara moja kuhakikisha usalama na ufunguzi.
Ⅱ. Mfano Wafanyaji wa Kurekebisha Pressure
Ufundi huu unatoa mifano ya kurekebisha pressure ya tatu stage, kujitumia mfululizo wa gas, cable chamber, na pressure relief chamber tofauti kwa ajili ya kukurusha pressure kwa uhakika wakati wa matatizo:
1. Ujenzi Mkuu
- Relief Chamber Layout: Inapatikana chini ya gas na cable chambers, kujitolea kwa kijani kwa kutumia perforated baffles.
- Wax-Sealed Vent Holes: Baffle kati ya gas chamber na relief chamber (first baffle) na baffle kati ya cable chamber na relief chamber (second baffle) ina 9–18 wax-sealed vent holes.
- Redundant Venting Channels: Relief chamber's upande wa kulia una 3–6 through-holes vilivyofungwa kwa muda kwa kutumia plugs, kama njia ya pili ya venting.
2. Smart Trigger Mechanism
- Normal Operation: Wax ya sealing ya melting point juu (imewezeshwa kudhibiti joto la vifaa vyenyeleweka) hutetea airtightness.
- Fault Conditions: Arc-induced high-temperature gas (> wax melting point) hunyoka wax, kunaruhusu gasi kuingia kwenye relief chamber kwa kurekebisha pressure ya first-stage.
- Pressure Persistence: Ikiwa pressure imebaki juu, gasi huondokanya plugs kutoka kwenye through-holes, kunapunguza kwenye nje kwa kuzuia mvuto wa cabinet.
3. Eco-Friendliness & Maintenance Optimization
- Recyclable Wax Film: Relief chamber walls ina film na pre-cut openings kwenye vent holes/plugs. Wax iliyonyoka hutambua film baada ya matatizo kwa easy cleanup and recycling.
- Green Insulation Medium: Gas chamber imefunika na air/nitrogen hutetea zero-pollution venting, kuwa na standards za mazingira.

Ⅳ. Thamani ya Kutumia
Mfano huu wa tatu stages—physical isolation, smart wax-triggered release, na redundant venting—unyatiliza vita kati ya RMU airtightness na usalama:
- Hupunguza Uharibifu wa Vifaa: Husababisha shock pressure kuhakikisha integrity ya cabinet.
- Hutetea Usalama wa Watu: Venting rahisi hutetea explosions na kudhibiti hazards.
- Hupunguza Gharama za Lifecycle: Wax recyclable na mifano yenyeleweka yahakikisha uzalishaji wa gharama chache.
Ideal for: Urban grid ring main units, compact substations, na industrial power distribution systems yenye ukosefu wa space/safety.
Ⅴ. Muhtasara
Na ujenzi wa kimekta na smart materials (high-MP wax), mfumo huu wa kurekebisha pressure unatoa jump katika performance ya usalama kwa RMUs. Kujitegemea, eco-friendliness, na cost-efficiency, unastand as solution ya usalama sahihi kwa next-generation smart power distribution equipment.
