1 Summary
1.1 General
(Figures 2/1 to 2/8)
The vacuum circuit-breakers of type VD4 are
intended for indoor installation in air-insulated
switchgear systems. They have a switching
capacity capable of handling the loads occuring
at start-up and shutdown of equipment and plant
units both in normal and in fault state.
Vacuum circuit-breakers have particular advan-
tages for use in networks where there is a high
switching frequency in the working current range
and/or where a certain number of short-circuit
breaking operations are expected. Type VD4
vacuum circuit-breakers are suitable for autore-
closing, and have exceptionally high operating
reliability and long life.
The vacuum circuit-breakers of type VD4,
designed in column form, can be supplied both
as individual units for fixed installation and
mounted on chassis. Their basic structure is
shown in figures 2/1 to 2/8.
1.2 Standards and specifications
1.2.1 Switchgear manufacture
The switchgear complies with the following
specifications in accordance with DIN VDE and
the relevant IEC publications:
• VDE 0670, part 1000 and IEC 60694
• VDE 0671, part 100, and IEC 62271-100.
1.2.2 Installation and operation
The relevant specifications are to be taken into
account during installation and operation,
particularly:
• DIN VDE 0101, Power installations exceeding
AC 1 kV
• VDE 0105, Operation of electrial installations
• DIN VDE 0141, Earthing systems for special power
installations with rated voltages above 1 kV
• Accident prevention regulations issued by the
appropriate professional bodies or comparable
organisations.
In Germany, these comprise the following safety
regulations:
– Health and Safety at Work Standards BGV A1
and BGV A3
• Safety guidelines for auxiliary and operating
materials
• Order-related details provided by ABB.
1.3 Operating conditions
1.3.1 Normal operating conditions
Design to VDE 0670, part 1000, “Common
specifications for high-voltage switchgear and
controlgear standards“ and IEC publication
60694, with the following limit values:
• Ambient temperature:
– Maximum +40 °C
– Maximum 24 hour average +35 °C
– Minimum (according to
“minus 5 indoor class”) –5 °C
• Humidity:
– the average value of the
relative humidity, measured over
a period of 24 h, does not exceed 95%
– the average value of the water
vapour pressure, over a period
of 24 h, does not exceed 2,2 kPa
– the average value of the
relative humidity, over a period
of one month, does not exceed 90%
– the average value of the water
vapour pressure, over a period
of one month, does not exceed 1,8 kPa
• Maximum site altitude:
≤ 1000 m above sea level.
1.3.2 Special operating conditions
Special operating conditions are to be agreed on
by the manufacturer and user. The manufacturer
must be consulted in advance about each special
operating condition:
• Site altitude over 1000 m:
– Allow for the reduction in the dielectric
strength of the air.
• Increased ambient temperature:
– Current carrying capacity is reduced.
– Provide additional ventilation for heat
dissipation.
• Climate:
– Avoid the risk of corrosion or other damage in
areas:
• with high humidity and/or
• with major rapid temperature fluctuations.
– Implement preventive measures (e.g. electric
heaters) to preclude condensation pheno-
mena.

Shown with the spring energy storage mechanism in the
discharged state. The wiring diagram comprises the
basic components and all further equipment options for
the various VD4 types. The scope of equipment possible
within an individual type series is listed in the relevant
switchgear list, and the equipment fitted in each indivi-
dual case can be found in the order documentation.
Note:
Shunt releases and blocking magnets are fundamentally
wired with rectifiers (e.g. magnet holder 40 with integrated
rectifiers -V1, -V2, -V3 and -V9).
Rectifiers function as free-wheeling diodes if d.c.-supply.
– V3 Series rectifier for – Y3 and – K0
– V4 Series rectifier for – Y4
– V9 Series rectifier for – Y9
– M0 Charging motor for spring

– K0 Anti-pumping relay
– R0 Series resistor
