<p>A high-voltage switchgear having a fixed and a moving contact member includes a hydraulic drive for operation of the moving contact member having a piston and cylinder configuration with a piston coupled to the moving contact member. A fluid reservoir configuration supplies fluid under pressure to the piston for driving the piston. A compressor unit at ground potential charges the fluid reservoir configuration. Electrically-insulating, pressure-resistant lines respectively connect the compressor unit with the piston and cylinder configuration and with the fluid reservoir configuration. The piston and cylinder configuration and the fluid reservoir configuration are disposed spatially close to and at the same electrical potential as the moving contact member.</p> |
