TPS Switchgear Air-Insulated.

TPS Switchgear

TPS Characteristics

(Single panel modular system)

Features


TPS is a complete MV switchgear range suitable for all the switching operations from 7.2kV to 24kV in the secondary distribution network.

Operating safely in a distribution network requires different switching points to obtain maximum service continuity in case of fault on the network. TPS can be used in various applications in the secondary distribution network.

Construction Characteristics


The switchboard is made of a metal structure composed of galvanized steel sheets that are assembled using rivets and bolts. This structure is built to withstand the electrodynamic stresses during the operation. A switch and earthing switch are fixed to this structure. A switch envelope made of epoxy resin makes the isolation possible between the structure and live parts. An operating mechanism, a mechanical position indicator and a voltage indicator are positioned in the front of the unit. The position of the switch is given by the mechanical indicator whereas the voltage signalling lamp indicates the presence of voltage. Visibility of main contacts can be checked through an inspection window positioned above the operating mechanism. In the front of the unit, there is a door giving access to different compartments, e.g. cables, fuses and measurement. When the unit is equipped with a low voltage auxiliary compartment it is situated in its upper part.

Flexibility:


  • A wide range of products covering your present and future requirements.
  • Modular cubicles adapted to future extensions.
  • Possibility to mount auxiliary components under voltage.
Options to anticipate the telecontrol.

Compact Dimensions


  • Small dimensions and reduced weights for easier handling and installation.
  • Reduced civil works costs.

Easy Installations


  • Small dimensions and reduced weights facilitate easy installation
  • Solutions adapted to cable connection.

Safety:


  • During the testing cable operation, it is not needed to break the earthing busbar system of the switchgear.
  • Interlock operated by earthing switch prevents unsafe operations
  • Additional interlocks to prevent incorrect operations.
  • All active parts of the TPS are contained in a sealed tank of stainless steel making it ideal for installation in difficult ambient conditions.

Visual Contact Visibility (Visible Isolation Gap)


To enhance the safety of the people the TPS switch is equipped with two positions indicators: 
  1. Mechanical position indication is fixed to the rotating contact shaft. 
  2. The position of main contacts is clearly visible from the inspection window. In this way the contact position can be checked easily by the operator.

TPR6 12-24kV Switchgear.

TPR6 Switchgear

Outdoor version up to IP54

No current derating
IP54

Features


  • Rated current of the RMU is guaranteed with no derating up to 55°C ambient temperature.
  • The protection against severe weather conditions, rain, humidity and dust is guaranteed by TPR6 robust design. The protection degree of the switchgear is IP54.
The enclosure is fitted with a front door and padlock. The gas piston facilitates the opening operation and maintains the door lifted in order to allow the normal operations or maintenance.

TPR6 Can be used in two types : 


  • Combination of functions in one SF6 tank (mono tank).
  • Single GIS SF6 filled unit combine to form an MV board.

TPR6 HP Plus

TPR6 Characteristics

(Gas Insulated Switchgear)

Features


TPR6 Plus is a maintenance-free, factory-assembled and type-tested medium-voltage switchgear. It is three-pole metal-enclosed and SF6-insulated. Vacuum circuit-breaker, switch-disconnector and disconnector modules are available. The core of the switchgear consists of hermetically welded containers made of corrosion-resistant stainless steel, accommodating the primary devices (circuit-breaker and three-position switch). The switchgear is sealed for life. The switchgear modules are interconnected by solid-insulated busbars outside the gas compartments.

Construction Characteristics


TPR6 is a completely “sealed for life” system with a stainless steel tank containing all live parts and switching devices. The structure can withstand the electrodynamics stresses during the operation. The operating mechanism, movable mimic and voltage signalling lamps are positioned in the front panel. Switches are operated by means of spring-operated mechanisms. Movable mimic gives the position of the switch whereas the voltage signalling lamp indicates the voltages. Fuses and cable compartment are easily accessible through the front door which is interlocked with the earth switch. If present, the low voltage auxiliary compartment is situated above the ring main unit.

PLS Pole Mounted SF6 Switch Disconnector

PLS Information

PLS Characteristics

(Pole Mounted SF6 Switch Disconnector)

Features


PLS is an SF6-insulated pole mounted switch disconnector designed for overhead line installations up to 40.5kV 630A/1250A. This outdoor switch disconnector is suitable for both remote control and manual operation with excellent load breaking and fault making capacity. The tank fulfils the requirement of “sealed pressure system” meaning that there is no need to add gas during its expected lifetime.

Construction Characteristics


The stainless steel tank is particularly suitable for providing protection against the extremes of heat, snow, corrosion, moisture and salt in the most demanding climatic conditions.PLS is easy to install due to its reduced dimensions and weight and it is almost maintenance-free.
