4.1.3.2 Operation of the three position 

disconnector (motor operated 
mechanism)

The motor-operated three position disconnector 
operating mechanism is in principle identical to 
the manual mechanism, but additionally has a 
drive motor. The three position disconnector can 
thus be operated by the motor, or also manually 
as an alternative.

The three position disconnector is mechanically 
blocked when the circuit breaker is closed. Operation 
of the earthing switch is only possible when the 
disconnector is open, and vice versa.

Motor operation

Motor operation of the three position disconnector 
is possible when electrical controls (e.g. the operator 
controls of a control unit) are fitted on the panel. 
Operate the corresponding controls to switch the 
three position disconnector on and off. The switch 
position is indicated on the display of the control 
unit and mechanically on the operating mechanisms.

Manual operation
Operation of the disconnector

Turn the selector lever (4 in Fig. 4.1.3.1.3) 

counterclockwise and hold it fast.

Insert the operating lever through the released 

opening (5) onto the splined shaft.

Disconnector OFF 

 ON

Turn the operating lever clockwise until the stop 

is reached. (< 70°).

Withdraw the operating lever.

Turn the selector lever into the vertical position 

without using force.

Disconnector ON 

 OFF

Turn the operating lever counterclockwise until 

the stop is reached (< 70°).

Withdraw the operating lever.

Turn the selector lever into the vertical position 

without using force.

Operation of the earthing switch

Turn the selector lever (4 in Fig. 4.1.2.1.3) 

clockwise and hold it fast.

Insert the operating lever through the released 

opening (7) onto the hexagon.

Earthing switch OFF 

 ON

Turn the operating lever clockwise until the stop 

is reached (< 70°).

Withdraw the operating lever.

Turn the selector lever into the vertical position 

without using force.

Earthing switch ON 

 OFF

Turn the operating lever counterclockwise until 

the stop is reached (< 70°).

Withdraw the operating lever.

Turn the selector lever into the vertical position 

without using force.

4.1.3.3 Emergency operation of the three position 

disconnector (motor operated mechanism)

If the mechanism motor becomes defective or the 
auxiliary power fails when the three position 
disconnector is in an intermediate position, manual 
operation is only possible by performing work on 
the operating mechanism. This work may only be 
performed by qualified personnel. In such a case, 
please inform ABB Service Department.

If the three position disconnector is not in an 
intermediate position on failure of the auxiliary 
voltage, the operating mechanism can still be 
operated as described in 4.1.3.1 even without the 
auxiliary power. When blocking magnets are used 
for the selector lever, the mechanism can only be 
deblocked by qualified personnel. In such a case, 
please contact the ABB Service Department.

4.3 Gas monitoring with gas density manometer

The high-voltage compartments must have 
sufficient gas pressure during operation. (Please 
consult the table entitled “Technical data” in section 
10 for the pressure levels.) The insulating gas 
pressure is monitored during operation by gas 
density manometer (temperature- compensated).

If the gas pressure falls below the alarm level, a 
signal to top up the insulating gas is issued. The 
signal appears at a warning lamp (Fig.4.3.1) in the 
operator control area, or on a panel control unit.

When systems are isolated for a relatively long 
period the auxiliary power supply should be 
maintained to monitor the insulating gas density.

4.4 Operation of the isolating device for voltage 

transformers and voltage sensors

Isolate the relevant switchgear section 
before connecting or disconnecting 
voltage transformers or voltage sensors.

Comply with the safety regulations to EN 50110.

Check the switchgear section for the off-circuit 

condition as described in section 5.1.

Earth the switchgear section and secure the 

working area in accordance with section 4 and 
EN 50110 standard.

Switch the mcbs 

1)

 of the relevant operating 

mechanisms off in order to prevent the 
switchgear section being energized by remote 
control.

The operating mechanism for the voltage 

transformer isolating device is located in the cable 
termination compartment on the righthand side 
wall (Fig.4.4.1).

Dismantle the cover on the cable termination 
compartment. This is done by removing the two 
screws above the cover and pulling the cover 
upwards.

The controls and indicators for the voltage 
transformer isolating device are shown in Fig.4.4.2. 
Check the switch position indicator (5 and 6). The 
isolating device can be secured with a padlock (3). 
Remove the padlock before operating the device.
