Product Information

 

1. VITZROTECH PGS & GLBS INTRODUCE (OUTDOOR TYPE)

    (Gas Insulated Load Break Switches For Underground & Pole Mounted)

 1-1 GLBS (Gas Insulated Load Break Switches For Underground)

 

  ● VITZRO TECH Gas Insulated Load Break Switch is a SF6 gas-insulated multi-circuit   

      switch that is installed on ground or underground at 22.9kV-Y or 22kVΔ underground  

      distribution line. It is an optimal product that uses SF6 gas as the insulating medium  

      superior for its arc extinguishing capability and the operating mechanism is a single- 

      operation method with 3-ground circuit for distinguishing the lines and branch lines. 

   

  ● Switch Body 

    - It is a 3-phase integrated operating, single-tank type that consists of switch, auxiliaries based on the  

       operation method, cabinet based on the installation type and so on. 

    - It is equipped with a ground switch for each circuit and it is designed so that the operating state of the  

       ground switch can be easily checked outside. 

    - The body cabinet is 3 mm or bigger and the front part where the bushing is mounted is 5 mm or bigger

      and both are manufactured using a stainless steel plate [STS304L] that can endure the inner gas  

      pressure. It is designed to have a stable structure with strong electrical and mechanical characteristics

      and durability.

    - Bolts are not used in order to prevent gas leak and it is completely enclosed by TIG welding. The  

      insulating material used in the inner part is the bisphenol, epoxy resin with excellent resistance to  

      electrical and mechanical characteristics and SF6 gas.  

 

  Operating Device 

    - The operating device of the switch is divided into a main circuit part and earth part. 

       It is designed to require no special skills and all 3-phase contacts are opened / closed imultaneously  

       and the switching speed is always consistent regardless of the operation method.

    - An automatic switch enables the mechanical closing/opening, electrical closing / opening and remote  

       operation (after installing a separate terminal and communication device) of the main circuit part.  

       However, the closing (earth)/opening of ground switch part can be manually operated on site. 

    - An interlock device is applied so that the closing (earth) operation of the ground switch is not done  

       unless the main circuit is opened and the closing operation of the main circuit is impossible at closing  

       (earth) state f the ground switch. 

   

  ● Cabinet 

    - The cabinet and the base are made up of stainless steel plate [STS304L] with size of 2.0 mm or bigger

       and 3.0 mm or bigger respectively. It is structured so that water does not form a pool in the cabinet.

    - The cabinet is designed and manufactured so that it is easy to connect and disconnect cables, detect  

       current, check earth and phase and so forth by opening the cabinet door easily. In addition, automatic

       voltage transformer (PT) for power control is installed in the lower part of the body and a door is 

        installed in the lower-side part of the cabinet for easy replacements.

    - The cabinet is coated in Munsell NO. 7.5GY 3.5/2 (green color) when installed in green belt and in  

       Munsell NO. 5Y 7/1 (gray color) when installed in sidewalk and other areas. 

    - Product Standards : IEC 60265-1, IEC 60694 

   

  ● Bushing Part 

    - It is structured to connect to the 600A deadbreak-type connector that is regulated in IEEE 386 and it is

      installed in the body part using bolts and it is in an O-ring enclosed structure for full enclosure.

    - A flange is made up of epoxy material and the flange surface that is connected to the body is

     connected based on IEEE 386.

 

 1-2 PGS (Gas Insulated Load Break Switches For Pole Mounted) 

 

  ● VITZRO TECH Gas Insulated Load Break Switch is a switch that is used at 22.9kV-Y /  

      10kV-Δ overhead distribution line applied with SF6 gas as the insulating medium which  

      is superior in terms of arc extinguishing. It is an optimal product to distinguish the  

      overhead distribution line and to be used as a branch switch with the operating  

      mechanism, a spring toggle method. 

   

  ● Switch Body 

    - It is a 3-phase integrated operating single-tank type that consists of a switch body, mounting tool and  

       control box. It easy to arm the concrete pole or power line and it can be installed stably. It is designed

       in a simple structure for an easy maintenance work.

    - A stainless steel plate ( STS304L) of 3 mm or bigger is used for the tank cabinet and it has a sufficient

       electrical and mechanical strength. Each part of the switch is simple and durable and the opening and

       closing are operated smoothly and accurately. There is no half-closing or half-opening during the  

       opening /closing operations, it is not opened / closed due to vibrations or other causes and it is  

       structured so that there is no water pool at any part of the switch. 

    - Bolts are not used in order to prevent gas leak and it is completely enclosed by TIG welding. The  

       insulating material used in the inner part is the bisphenol, epoxy resin with excellent resistance to  

       electrical and mechanical characteristics and SF6 gas. 

    - O-Ring that is used for the enclosure at the bonding part is made up of EPR and FPM that is heat-

       proof, weather-protected and gas-proof and the surface of the O-Ring is covered with grease that is  

       heat- proof, weather-protected and gas-proof.

 

  ● Operating Device 

    - The operating device of the switch is divided into a main circuit part and earth part. 

       It is designed to require no special skills and all 3-phase contacts are opened/closed simultaneously

       and the switching. speed is always consistent regardless of the operation method.

    - In case of an automatic switch, it can be operated by an electrical switching device of the control box  

       and by a manual operating device of the body. It can be operated based on the designated operation  

       method [Local/Remote]. 

 

  ● Bushing Part 

    - It exceeds the standard impulse insulation density of the switch and all bonding parts are treated so

      that gas does not leak and air does not get in. It is structured to maintain the mechanical sticking force.

    - It is made up of a qualitative magnetic material that has the freezing and thermal capability, it is firm  

      enough to endure the mechanical impulse and it is moist-proof. In addition, it used a polysil insulating  

      material that is molded by an advance insulating material, polymer concrete, which our company

      retains the patent, and it maintains the dielectric strength even at poor operational conditions since the

      electrical and mechanical strength and arc extinguishing are superior.

 

  ● Outside Connecting Terminal 

    - It maintains the sticking force by connecting the terminal or lead-out line to the bushing. 

    - An insulation wire for high-voltage which is flexible and weather-protected is used and the nominal  

       sectional area of the conductor and the wire composition are 125 sq (159/1.0) or bigger for 400A and  

       200 sq (19/14/1.0) or bigger for 630A and the required length is 2 m. 

    - The lead-out line is water-proof which prevents the water from entering and the connecting part within

       the mold cone is structured not to allow water from entering. 

    - The connecting part of mold cone and lead-out line is centralized with an electric field and it is glued  

       firmly so that the connecting part is not disconnected and its surface is smoothly treated. 

       Applied Standard IEC 60265-1
