Product Description
iUniuswitch Air Insulation Ring Main Unit
iUniswitch, the light flexible switchgear developed as a modular, simple to apply design, with fewer components, providing a high reliable, quality and safe product for you, our Customer. By reducing the number of components, utilising modern materials correctly, we have developed an environmentally and user friendly product. The simple design and construction of iUniswitch will stand the test of time for generations to come.
iUniswitch is an air insulated (AIS), metal enclosed, switchgear cubicle design of the next generation developed through continuous innovation and vision to meet the changing market needs.
iUniswitch provides long-term technical solutions for various applications. Safety, user friendliness and environmental con- cerns have been the driving force in the development of the switchgear.
Feature
iUniswitch product provides our Medium Voltage Customer with the best solution for heavy duty switchgear in a size only a little than a single tank Ring Main Unit while including:the flexibility in meeting our Customers specification and accomodating on future change and upgradingthe options include complete control, measuring and protection systems
iUniswitch Air Insulation Ring Main Unit Construction
Metal enclosed switchgear
iUniswitch Air Insulation Ring Main Unit
Busbar compartment
The busbar compartment is located on the top of the cubicle. This compartment contains the main busbars that intreconnect between switchgear cubicles.
Switching compartment
A 3-position SF6 switch disconnector with epoxy cast resin housing is provided with inspection windows and available also with gas density indicator.
Cable compartment
75 % of the space in the switch disconnector cubicle is reserved for power cable connection making it possible to use both 1- and 3-phase cables with most simple unscreened terminations. Space is also adequate for cubicle accessories such as surge arresters, current transformers, second earthing switch etc. The door has an inspection window and safety interlocking as standard. For cable entry there are 3 individual cable gland plates in the bottom with support for a suitable dimensioned cable clamp. The bottom and the threshold of the cubicle can be removed for ease of cable installation.
Mechanism, interlocking and low voltage compartment
Behind a hinged door (which serves as control panel) are located the spring operating mechanism with position indicator and the mechanical interlocking unit. There are also facilities for cubicle accessories such as: auxiliary contacts, tripping coil, emergency tripping mechanism, capacitive voltage presence indicating system, key interlocks and motor operating device. Space is also provided for control circuits and measuring instruments as well as a protection relay. In the 750 wide cubicles there is also a second indentical compartment for further accessories.
The upper part of the cubicle, including the busbar compart- ment, the switch disconnector and the mechanism and low voltage compartment is separated from the lower part and the cable compartment. Because of this it is possible to carry out maintenance, repair and upgrading of the unit in the lower module while the switchgear is in service.
