33 KV Air Brake Switches
Air Brake Switch On load
Nikum make Center rotating type triple Pole outdoor on
load disconnecting switches for higher line current breaking capacity for
line Isolators. The isolators are having a fixed and moving contacts made
of HDHC. Copper and die forged fingers of phosphorus bronze having inherent
non deteriorating spring qualityat high temperature and corrosion proof.
The
assembly of fixed and moving contains is based on self compensating princile,
to withstand both thermal and dynamic stresses of short circuit current
and still carry the continuous rated current with plenty of margin under
the maximum specified temperature. All ferrous parts are hot dipped galvanized
and non ferrous parts are heavily tin platted to provide protection against
corrosion, contacts for higher current rating are silver platted.
Earth switch can be easily installed on each pole at either end and interlocked
mechanically with the main switch. the auxiliary switches can be provided
for man as well as for earth switch. Electrical interlock can be provided,
Electrical moter drive mechanism complete with reduction gear and torque
limiting safety features can also be provided. Isolators are manufacturers
in normal and solid core post insulators range covering from 6.6KV to 220KV.

Automatic HT Breaker
Nikum induction has emergad as a leading manufacturer of electrical breaker
in india , today nikum induction manufactures a multy operation h.t. breaker
for 11 kv. 33.kv. The product of nikum induction has been supply in india
and export to
This
h.t. capacitor breaker suitable for 11kv , 33 kv. Depending on load pattern
, will close or open automatically/ manually to connect and disconnect the
load /capacitor bank to the line, the breaker are specially design for h.t.
capacitor connect or disconnect automatically according to load/power factor,
to the line.
There are two option in the breaker to connect the capacitor bank to line
automatically or manual or control to a.p.f. c. Relay, according to load pattern,
the design of breaker is maintenance free, easy operation,
the automatic breaker are design for that industries they require multy operation
/switching for capacitors bank connect and disconnect to the h.t. line .the
h.t. breaker provides not only reactive power compensation at overload current,
but also prevents over-voltage problem at the receiving end during low load
condition by switching on and off the capacitor bank in the circuit respectively.
automatic switching on or off the capacitors bank whenever the load current
exceeds a re-set value, the setting of load current is adjustable up to 2oo
amp. continuously.
In the event of line current exceeding a certain specified limit, the c.t.
mounted on ryb phase operates through the control unit and closing command
is given to the closing solenoid which close the interrupter, thereby connecting
the capacitor bank in the circuit and thus improving the power factor. When
line current is reduced, to a specified value control, unit gives a tripping
command to the trip coil thereby disconnecting the capacitor bank. The power
to the closing solenoid and tripping coil is also taken d.c. voltage
