Innovatively designed components in the newly released hybrid switchgear gives internal components complete immunity from all environmental conditions, ensuring lifelong reliability.
Sydney, Australia, 15 October, 2003 - ABB, the leading power and automation technology group has released its revolutionary PASS (plug and switch system) M00 72.5kV hybrid switchgear.
The PASS concept is a hybrid of ABB’s traditional air insulated (AIS) and SF6 metal-clad gas insulated (GIS) switchgear units designed as self-contained switching modules suitable for use in outdoor substations. It requires just one 700 x 700 millimeter foundation block for the bay.
Now available after completing rigorous type testing, the PASS M00 module retains all the characteristics of ABB’s M0 145kV module, and has been adapted for lower voltage substations. It is normally delivered completely assembled as a "72 kV bay in a box".
Each module is compact, energy-efficient, easy to install and virtually maintenance-free.
In an innovative design, the line and busbar disconnectors, as well as the earthing switches, are integrated in the breaking chamber. This gives these components complete immunity from all environmental conditions, thereby ensuring lifelong reliability, and eliminating routine maintenance of high voltage parts. This overcomes a major weakness of AIS substations.
Standard functions include current measurement, current interruption, disconnecting and earthing on both sides of the breaker, all of which can be customised.
Specifications are:
Rated voltage 72.5 kV
Rated frequency 50 / 60Hz
Rated current 2000 A
Rated L.I. withstand voltage 325 kV
Rated P.F. withstand voltage 140 kV
Rated short time withstand current (3s) 31,5 kA
Rated peak withstand current 80 kA
Temperature range -40° / +55° C
The PASS M00 will be featured on the ABB stand at the upcoming Distribution 2003 exhibition being held in Adelaide from 16-19 November.
