550kV 740kV Gas Insulated Switchgear HV (GIS)

Nàànwàrì Product:
   ZF28-550 type GIS/ ZH28-550 type HGIS na-akpọrọ otu n'otu site n'ebe mmalite, enwere ike inye aka ntụkwasị obere n'ọnụọgụgụ maka ebe mmalite dịka anyị chọrọ. O mere ikpe ikpe nke obere ma bụrụkwa n'asụsụ teknụzụ.
    Nàànwàrì a na-achọrọ ka onye ji eme, onye na-enye elekiri, osisi okporo, petrochemical, metallurgy, mining, building materials na ndị ọzọ dị mkpa n'ime industry.

Nnyocha na ọtụtụ ihe dị mma nke nàànwàrì:

• Mechanism spring kacha, nke na-ekwesịrị.

• Nnyocha na-enye aka nke dị mma.

• Nnyocha na-enye aka CB na-egosi dual break structure, na capacitor shunt site n'ikpe ikpe mgbe ha na-akpọta, enweghị aka nnyocha na-enye aka nke pụtara short-line fault na nnyocha na-enye aka nke pụtara short circuit bụ 63kA.

• E2-M2-C2 circuit breaker; E2 electrical endurance; M2 mechanical endurance.

• Nnyocha na-enye aka nke dị mma.

• Insulation level dị mma, partial discharge dị elu.

• Nnyocha na-enye aka corrosion.

• Designing tool dị mma.

• Basin-type insulator site n'alu flange; double sealing structure.

• Assembly technology dị mma.

• Domestic first high power spring operation mechanism of circuit breaker na-egosipụta volume elu na-safe and stable, free of maintenance, nke na-ekwesịrị na nke na-enyere oil free and gas free requirements for operation mechanism.

•  Interrupter unit na-egosi capacitor shunt site n'ikpe ikpe mgbe ha na-akpọta. Enweghị aka nnyocha na-enye aka nke pụtara short line fault breaking capability.

• Insulation level dị mma na partial discharge dị elu. Nke a bụ company dị mfe na industry nke na-achọrọ: mgbe 80% power-frequency withstand voltage (80%×740kV = 592kV), partial discharge nke intervals bụ nke elu 5pC, partial discharge nke insulator bụ nke elu 3pC. Ọ dị mma nke IEC standard nke partial discharge bụ nke elu 5pC mgbe 1.2 times phase voltage (1.2×550/√3 = 381kV).

• Insulator quality dị mma na ekwesịrị. Basin-type insulator pouring process na-egosipụta international advanced level.

Technical Parameters:

Gịnị bụ ọtụtụ ihe dị mkpa maka operation nke GIS?

• Indoor SF6 equipment room nke operators na-eburu ochie: ventilate at least once per shift, ventilate for 15 minutes, air exchange volume should be greater than 3-5 times the air volume, and the air outlet should be installed in the lower part of the room; Equipment places that are not frequently visited by operators: ventilate for 15 minutes before entering.

• Mgbe ọ na-enwe ike, induced voltage nke shell and frame nke GIS enwere ike inye 36V site n'otu na-ewepụta operation and maintenance personnel.

• Temperature rise: enwere ike inye 30K site n'otu na-ewepụta operating personnel; Site n'otu na-ewepụta operator but not touched during operation enwere ike inye 40K; Individual parts nke enweghị ike ewepụta operator enwere ike inye 65K.

• SF6 switchgear inspection at least once a day, unattended substation inspection according to regulations. During the inspection, the visual inspection is mainly carried out, and the equipment is not abnormal, and a record is made.
