injury.

CAUTION: Indicates a potentially hazardous situation that, if not avoided, could result in personal injury

or equipment damage.

Safety Instructions

General hazard statements applying to this equipment are described in this section. Statements relating to specic tasks or

procedures are located throughout this manual.

DANGER: Contact with hazardous voltage will cause death or severe personal injury. Contact with Recloser

or Control Cubicle terminals should only be undertaken when equipment is isolated from

applicable sources of voltage.

WARNING: This equipment is not intended to protect human life. Follow all locally approved safety

procedures when installing or operating this equipment. Failure to comply may result in death

or severe personaly injury.

WARNING: Before working with equipment descriped in this manual carefully read and understand the

contents of this manual. Improper handling, installation, operation or maintenance can result

in death, severe personal injury or demage to equipment.

WARNING: Power distribution equipment must be properly selected for the intended operation. It must be

installed, used and understand all relevant safety procedures. Failure to comply can result in

death, personal injury or equipment damage.

Denitions

The following abbreviations are used in this operating manual:

AR Automatic reclosing

CM Control module

CO Close open cycle

ISM Indoor switching module

LED Light emitting diode

MCB Miniature circuit breaker

Make time

The make time is the time period from the energising of the closing circuit to the time when the current begins to

ow in the rst pole.

Closing time

The closing time is the time period from the energising of the closing circuit to the time when all three poles make

contact.

Pre-arcing time

Interval of time between the initiation of current ow in the rst pole during a closing operation and the instant

when the contacts touch in all poles for three-phase conditions or the instant when the contacts touch in the

arcing pole for single-phase conditions.

Opening time

The opening time is the time period from energising of the closing circuit up to the time when all the switching

poles are separated.

Break time

The break time is the time period from the energising of the closing circuit up to the time when the arcs of all the

poles are extinguished.

Open-close time (during AR)

Interval of time between the instant when the arcing contacts have separated in all poles and the instant when the

contacts touch in the rst pole during a reclosing cycle.

Dead time (during AR)

Interval of time between nal arc extinction in all poles in the opening operation and the rst reestablishment of

current in any pole in the subsequent closing operation.

NC Normally closed contact

NO Normally open contact

PCD Pole center distance

SCADA Supervisory control and data aquisition

VCB Vacuum circuit breaker

VI Vacuum interrupter

General

In comparison to conventional circuit breakers, the Tavrida Electric vacuum circuit

breakers comprise of two components:

· The ISM (Figure 1)

· The CM for controlling the ISM and monitoring both modules (Figure 2)

Both modules must only be operated together and are meant for indoor

installations only. The possibility to choose ISM and CM separately allows any type

of switchgear to be easily equipped with regard to its primary and auxiliary circuits.

Figure 2

Compact design

Tavrida Electric develops and produces all vital parts of the circuit breakers themselves. The result of intensive

inhouse fundamental and material research are extremely compact vacuum interrupter and magnetic actuators.

Optimal selection of all components makes these the most compact and light weight vacuum circuit breaker in

the world.

Long life

Contact erosion is minimised by use of axial magnetic eld. All the switching elements are assembled axially and

symmetrically in one straight line. This means that all the mechanical movements are exclusively direct and linear.

30 000 operating cycles can be achieved with rated current without replacing or adjusting any components.

Maintenance free

The ISM is maintenance-free over the expected life of at least 25 years.

Highest availability

In addition to minimising the number of failure-critical components, the Tavrida Electric circuit breaker monitors

its status continuously. In the unlikely event that a fault occurs it is indicated and can be rectied before an unsuc-

cessful switching attempt is made. This leads to higher availability of the electric power supply system.

Design and Method of Operation: ISM and CM

The ISM vacuum circuit breaker uses three single-coil magnetic actuators, one per pole. The three actuators are

mounted in a steel frame and mechanically linked by a synchronizing shaft (Figure 3).
