36kV 40.5kV hangin-hanginan na metal-clad na ma-withdrawable nga MV Switchgear

Paglalarawan

Ang KYN61-40.5 (parehas sa unigear Z3.2) air-insulated metal-clad withdrawable switchgear (sa hulihan ay "switchgear") ay isang uri ng MV switchgear.

Ito ay disenyo bilang withdrawable module type panel, at ang withdrawable bahagi ay may VD4-36E, VD4-40.5 withdrawable vacuum circuit breaker na gawa ng Cooper Nature company. Maaari rin itong magkaroon ng isolation truck, PT truck, fuses truck, at iba pa. Ito ay applicable sa three phase AC 50/60 Hz power system,

at pangunahing ginagamit para sa transmission at distribution ng electrical power at control, protection, monitoring ng circuit.

Technical parameters:

Ano ang mga structural characteristics ng air-insulated metal armored withdrawable medium voltage switchgear?

Metal Clad:

• Ang cabinet ay gawa mula sa high-quality cold-rolled steel plates, na pinroseso at binendo gamit ang CNC equipment. Ito ay inasambleado sa isang robust metal-clad structure gamit ang bolts, nuts, at iba pang fasteners. Ang disenyo na ito ay nagbibigay ng mataas na mechanical strength at protective capabilities, na effectively preventing external objects mula sa collision at pagkasira ng internal electrical components.

Draw-Out Design:

• Ang major electrical components, tulad ng circuit breakers, contactors, at relays, ay nakalagay sa drawable trolleys. Ang trolleys at ang cabinet ay naka-align precisely gamit ang guide rails at positioning devices, na nagpapadali ng maintenance at repair. Ang trolleys ay maaaring i-withdraw nang hindi nag-i-interrupt ng power, na nagpapahintulot sa replacement o repair ng faulty components. Ito ay significantly enhances ang reliability at continuity ng power supply.

Air Insulation:

• Ang air ay ginagamit bilang insulating medium, na may appropriate air gaps maintained between phases at between the phases at ground upang matugunan ang insulation requirements. Ang disenyo na ito ay simple at cost-effective, at ito ay hindi nagdudulot ng issues tulad ng insulation aging o environmental pollution. Gayunpaman, ang insulating properties ng air ay mas susceptible sa environmental factors. Sa harsh environments, tulad ng high altitudes, humid conditions, o areas na may heavy pollution, ang insulation distance ay maaaring kailanganin ng pag-increase upang matiyak ang adequate performance.
