Ang grounding switch nga 40.5kV ini gigidahan para sa high-voltage gas filling cabinets, nagamit og SF6 gas insulation aron mobangon ug mapabilin ang circuit grounding sa medium-to-high voltage systems. Ang iyang sealed structure naghatag og robust performance labi na kon may dust, moisture, ug extreme temperatures, sama usab naggaminas sa installation space.
Gigidahan usab kini og multi-level mechanical interlocks, nga mahimong maayo nga makapahibalo sa improper grounding (e.g., live grounding) aron moprotektahan ang maintenance personnel ug equipment. Ideal kini para sa substations, industrial power grids, ug renewable energy facilities, kompyable sa IEC 62271 ug GB standards. Ug may long mechanical lifespan ug low maintenance needs, naghatag kini og stable grounding protection alang sa high-voltage gas-insulated cabinet systems.
1, pag-split sa grounding switch: ang operator moadto sa grounding switch operation hole, reverse needle rotation makakapag-split sa gate. Sa panahon niini, ang center sa panel magbabahin sa closing ug closing signs, ug (ang lower door plate mag-lock).
2, ang load switch operating hole, clockwise rotation (electric operation press the closing button) makakapag-switch on. Sa panahon niini, ang dividing and matching indicator forms.
Duha, power failure
1, load switch split: ipress ang mechanical operation button sa ilalum sa panel (electric operation press down the gate button) aron maswitch-on ang load switch. Sa punto niini, ang closing and closing indicator & appears.
2, grounding switch closing: ang operator moadto sa grounding switch operating hole. clockwise rotation makakapag-switch on. Sa panahon niini, ang dividing and matching indicatorⓍforms.
Be careful:
1, kon ang power supply gikan sa upper end sa switch, ang live display switch closed and extinguished, shiny.
2, kon ang power gikan sa lower end sa switch, ang live display is always bright when the power supply, grounding switch and prohibition! It is suggested that three melting pipes should be replaced at the same time when the dissolving tube is replaced.
