Cubicle (Fully Gas Insulated)

Project Details

Arlisco is now one of the biggest suppliers of MV gas-insulated switchgear (GIS) in Indonesia. Today over 3500 medium voltage functional units have been installed in the electrical networks of electrical utilities in all region of Indonesia. MV gas-insulated switchgear systems have been designed to withstand the testing according to IEC 62271-200.

Key Components :

Load Break Switch

High duty load break switch which is the multi blade arc divider type.

The three-position switch includes the functions of load break switch, disconnector and earthing switch  in a single unit.

Feature:

  • 3 position switch-disconnector (Open-Close-Earth)
  • Operator independent operation 
  • Mechanical Endurance for Switch (1000 times for manual and motor)
  • Mechanical Endurance for Earthing Switch (1000 times for manual)

Rotating Arc Circuit Breaker (CB)

A rotating arc circuit breaker (CB) can be described as a CB which generates  a magnetic field for driving the arc. During the breaking process, initially the arc introduces a current into the coil. Then the coil generates a magnetic field and the arc starts to rotate due to forces of the magnetic field. Finally the arc extinguishes by cooling down and totally dissipates when passing to the zero position of the sine function.

Vacuum circuit breaker (VCB)

All LSV type modular cubicles incorporate a compact three-pole circuit breaker with vacuum breaking technology thanks to the axial magnetic field type vacuum interrupter (VI). Two massive copper contacts, one fixed and the other moving, inside the VI’s ceramic body form the main connection parts of the VCB circuit. During the switching off, an arc occurs in the vacuum contact chamber from the moment the fixed and moving contacts are separated. Once the quenching distance is reached, the arc is quenched on the zero crossing to break the current.

Features:

  • Mechanical endurance : M2 (10.000 Operations)
  • Operating sequence with reclosing :
    • O-0.3 s-CO-15 s-CO
    • O-0.3 s-CO-3 min-CO

Main compartment :

  • Gas tank

This is a gas-tight welded tank made from stainless steel, which houses all the live parts including the busbars. Busbars are also located in the MV compartment. The busbars of the individual sections or blocks of panels are linked to one another via special bushings including controlled silicone insulation and coupling pieces.

  • Gas leakage indication

Each gas tank has a pressure display for verification of the gas overpressure within, allowing its functional safety  to be inspected. To control the functional safety, each gas tank is equipped with a pressure indicator.

  • Driving mechanism

The sturdy drives, operated by spring or stored energy mechanisms, of the load break and earthing switches, and rotating arc circuit breakers (CBs) are located above the HV compartment. The spring operated drives are low maintenance components and the tripping mechanism of the stored energy operated drives of transformer and CB panels should be operated at least once every 10 years.

Arlisco Group

Arlisco Elektrika Perkasa was established on September 17, 2015, by Tikno Sunjoto Handoko. Which producing more advanced and sophisticated Medium Voltage electrical materials such as SF6 and Air Insulated Switchgears, Pole Mounted Reclosers, Pole Mounted SF6 Load Break Switches, Pole Mounted Fault Interrupter and Cable Accessories. Arlisco Elektrika Perkasa, is a growing manufacturing company which now have their own R&D Team with intention to expand in manufacturing other electrical equipments, mostly on the medium voltage side.
