Hybrid Switchgear PASS M0S - 420 kV
Compact switchgear assembled and high-voltage tested in factory, for rapid energizing in 24 hours
PASS M0S belongs to the innovative high-voltage hybrid switchgear family PASS (Plug and Switch System). PASS encloses all functions of a complete switchgear bay in a single module. The hybrid design makes use of traditional air-insulated busbars to connect with other equipment in the substation while enclosing the following bay functions in a single-phase gas-insulated housing:
- Circuit breaker
- Combined disconnector and earthing switches
- Voltage transformers and Voltage sensors
- Current Transformers
- Motor drive option
- Fast earthing switch option
- Plug in cables option
PASS modules are completely factory assembled and tested, ready for rapid installation and energization. This goal is reached by a simple, safe and effective tool to perform the rotation of bushings from service to transportable position, due to a robust sealing interface capable of ensuring tightness during and after rotations.
PASS M0S is available in numerous configurations including single busbar, double busbar, double-circuit breaker, and various other customized configurations are possible.
Applications
- Integration of renewables power to the grid
- Remote mining connections
