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

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.
