Disconnectors and earthing switches – The Securing

even under adverse climatic conditions. Disconnectors
and earthing switches are often offered as a combination
of both.
R-HG11-227.tif
1
Disconnectors and earthing switches are used to protect
personnel while working on operational equipment and
must therefore be very reliable and operationally safe –
Disconnectors have to isolate downstream operational
equipment – i.e., de-energised equipment – from the
connected circuits. Thus they establish a visible isolating
distance in air towards downstream operational equipment.
6
Siemens HG 11.31 · 2008
The task of an earthing switch is to earth de-energised parts
of the switchgear and – in the case of multi-pole earthing
switches – to short-circuit them at the same time.
3D Disconnectors and Earthing Switches
Description
Construction and mode of operation
Application
Disconnectors and earthing switches are suitable for indoor
installations up to 36 kV. Due to their cast-resin ribbed insulators, the disconnectors and earthing switches can also
be used with high air humidity and occasional condensation,
e.g., in tropical areas.
1
The devices are protected against corrosion. Steel parts are
either galvanised and yellow-passivated, or electrostatically
coated with epoxy-resin powder over a phosphate layer.
The switching devices can be installed in any position with
horizontal shaft. Designs for installation with the shaft in
vertical position are also available.
Endurance
R-HG11-227.tif
Normally, disconnectors and earthing switches are operated
very rarely. Therefore they are not designed for a high number of operating cycles. The mechanical endurance and the
contact endurance are:
– 5,000 operating cycles for the disconnector
– 1,000 operating cycles for the earthing switch.
Functions of the switching devices
3DA/3DC disconnectors have the following functions:
– Opening or closing circuits when either negligibly small
currents have to be switched off/on or when there is no
significant voltage difference between the circuits to be
disconnected or connected.
– Establishing an isolating distance between the terminals of
each pole in the open position.
The task of 3DD/3DE earthing switches is to earth deenergised parts of the switchgear and – in the case of
multi-pole earthing switches – to short-circuit them at the
same time.
2
Short-circuit capability
Earthing switches built on disconnectors or used as independent devices have to be interlocked in presence of peak
withstand currents above 50 kA if the earthing switch is
installed with the peak withstand current flowing through
the earthing switch in direction 2 according to the drawing
shown on the right. In this direction, strong opening forces
are effective.
HG11-2657 eps
The short-circuit capability of closed disconnectors and
earthing switches is tested according to VDE. Due to the
loopless circuit, the disconnectors need not be interlocked
against being opened by short-circuit forces.
1
1 Energy direction produces no or small opening
forces; permissible without interlock up to the
rated peak withstand current
2 Energy direction produces strong opening forces;
permissible without interlock up to a peak value
of 50 kA
Sufficient interlocking is guaranteed for motor operating
mechanisms as well as for self-blocking manual operating
mechanisms (e.g., spherical joint mechanism).
For earthing switches built on a disconnector, the mechanical interlock between the disconnector and the earthing
switch is a simple means to exclude the disadvantages of the
energy direction with opening force effect.

3D Disconnectors and Earthing Switches
Description
Operating mechanisms
Motor operating mechanism
1
The motor operating mechanism – provided for disconnectors and earthing switches type 3D – mainly consists of a DC
compound-wound motor, degree of protection IP00, which
drives the eccentric shaft of a free-wheeling mechanism via
a single-step spur gearing. The free-wheeling mechanism
makes the crank (2) rotate counter-clockwise. The crank is
linked with the drive lever through a short drive rod, and the
drive lever is connected with the operating shaft (4).
1
A 180° turn of the crank produces a switching angle of 90°
at the operating shaft. In the end positions of the switching
device, the drive motor is de-energised via built-in position
switches. If an AC motor operating mechanism is required, a
rectifier is installed additionally.
2
4
The time from initiation of the command until reaching the
end position or arrival of the feedback (total operating time)
is 3 s as a maximum at the lowest value of the operating
voltage.

If the auxiliary voltage fails, the motor operating mechanism
can be emergency-operated. The auxiliary mechanisms

fixed-mounted in the switchgear panel and required for each
motor operating mechanism.

5b (motor operating mechanism for earthing switch top-right)

Siemens HG 11.31 · 2008
HG11-2658a eps
4a
The simplest design consists of a straight shaft running
horizontally from the eccentric shaft (pin for emergency
operation) of the motor operating mechanism to the front of
the switchgear panel. There it is guided in a bearing plate,
and ends with an operating pin. The switching operation is
performed by means of an auxiliary crank, which is only
required once for the switchgear assembly.
If the direct way to the panel front is not possible, the
straight shaft can be equipped with a spherical joint at the
motor operating mechanism. This built-on system enables
deflecting the shaft by max. 10° to all directions. Another
design is provided for motor operating mechanisms that are
hard to access. This operating mechanism is designed with a
flexible shaft, which is also operated with the auxiliary crank.
For disconnectors and earthing switches in open switchgear
panels, a complete auxiliary mechanism 3CX6 is
recommended as crank.

Switching rod levers made of insulating material are always
used where the necessary minimum distances are not
reached. For fixing in the end positions, an elastic latch is
always provided for switching rod actuation (see interlocks).

Operation by means of a switching rod depends on the
mounting position and the accessibility. Switching rods are
made of glass-fibre reinforced polyester tube and can be
used in switchgear with rated voltages above 1 kV. These
switching rods are used to actuate the switching rod lever
(available as an accessory) mounted on the operating shaft.

For disconnectors and earthing switches a latch can be supplied, which latches tight in the end positions in an elastic

Mechanical interlocking
If neither the disconnector nor the earthing switch are
power-operated, mechanical interlocking is possible in connection with an electromechanical lockout. The electromechanical lockout is then mounted on the disconnector.
Electromechanical lockout
Electromechanical lockout devices can be installed on all
disconnectors and earthing switches without power operating mechanism. The lockout devices block the switching devices in the end positions when the solenoid is not excited.
In the intermediate position (faulty position) the lockout is
not effective. The magnet coils are suitable for continuous
operation.

Interlocks for motor operating mechanisms
Via switchgear interlocking system
For operation in connection with a switchgear interlocking
device 8TJ2, a poled relay is required to prevent maloperation. Interlocks on the disconnector can be omitted.
1
For operation in connection with a switchgear interlocking
device 8TK, no other auxiliary contactors are required.
1
Via auxiliary contactor
With an auxiliary contactor (with or without command
execution) and pushbuttons, additional protective measures
must be taken against impermissible switching operations.
2
Via changeover switch
The simplest possibility of control is a changeover switch.
However, adequate protective measures against impermissible switching operations must be taken here as well.

R-HG11-048a eps
Disconnectors and earthing switches can be equipped with
auxiliary switches with 2 NO + 2 NC or 6 NO + 6 NC contacts.
If there is a motor operating mechanism available, the auxiliary switch is located on the side opposite of the motor. The
rated current is 10 A.

The dielectric strength of air insulation decreases with
increasing altitude due to low air density. According to
IEC 62271-1, the values of the rated lightning impulse withstand voltage and the rated short-duration power-frequency
withstand voltage specified in the chapter “Technical Data”
apply to a site altitude of 1000 m above sea level. For an
altitude above 1000 m, the insulation level must be corrected according to the opposite diagram.

Order number structure
Built-on components and special versions («)
The disconnectors and earthing switches are described by a
9-digit order number. The positions 10 to 16, which are
provided for the usual 16-digit order number, are not
required. These 9 characters describe the primary data of the
switching devices. Built-on components such as motors,
interlocks, auxiliary switches, etc. are ordered by means of
order codes.
For built-on components and special versions, “-Z” is added
to the order number and a descriptive order code follows. If
several built-on components and special versions are
required, the suffix “-Z” is listed only once. If a requested
special version is not in the catalog and can therefore not
be ordered via order code, it has to be identified with Y 9 9
after consultation. The agreement hereto is made directly
between your responsible sales partner and the order
processing department in the Switchgear Factory Berlin.
