in modular extensible design up to 24 kV, 20 kA

7. Maintenance

7.1. General

Maintenance, repair work and subsequent

modifications must only be performed by skilled

personnel and in compliance with the operating

instructions, the accident prevention instructions and

the regulations of the liability associations.

Maintenance is used to ensure continuing trouble-free

operation and the longest possible service lifetime of the

switching device and the equipment integrated. It covers

the following, closely related areas in accordance with

DIN 31051 respectively:

•

Inspection:

Determination of the actual state

•

Maintenance:

Measures to preserve the nominal state (ensuring

trouble-free function)

•

Repair:

Measures to restore the nominal state.

The circuit-breaker panel is low- maintenance.

The gas tank is welded gas-tight and all components inside

are maintenance- free.

The SF

gas is resistant to ageing and is not consumed

during the switching operations.

Under normal conditions, the gas charge does not need to

be replaced during the operational life of the circuit-breaker

panel.

The vacuum circuit-breakers feature a simple and robust

design.

They have a long life expectancy. Their drives are low

maintenance and the vacuum contact chambers are

maintenance-free for their entire service lifetime.

Even frequent switching of operating and short-circuit

currents will not degrade the vacuum.

The maintenance intervals for the mechanical assembly

on the vacuum circuit-breaker are defined by the ambient

conditions, operating frequency and number of short

circuit breaks.
