Transformer substation is power appliance
in electric energy method that switches voltage, accept and distribute electric
energy and manage electric flowing path also as adjusting voltage. It connects
power grid of voltage with various levels by transformer. Here, the equipment
with the function of switching energy is transformer. Except for this, additionally,
it includes switching device opening and closing circuit, generatrix assembling
currents, mutual inductor for measuring and controlling, meter, relay
protection device, lightning protection device and dispatching communicator.
Some, like Combined
Substation even contains reactive-load compensation equipment.
Transformer
Transformer is the main device in
transformer substation. Supplied by transformer producers, you will find two-circuit
transformer, three-winding transformer and auto-transformer, also transformer
specially developed by transformer manufacturer, whose higher and low stress
share a winding inside every phase by extracting 1 head from high pressure
winding to act because the outlet of low stress winding. The voltage strength
is direct proportion to winding quantity whereas the present is in inverse
proportion to it.
Switching device
Switching device includes breaker,
disconnector, Load
Breaker Switch and higher voltage fuse that are all devices for connecting
or breaking the circuit. Right here, breaker is used to connect and break
circuit in the condition of power system normal operation and in the situation
of breakdown automatically break the circuit from breakage device under the
protection of relay protection device. As well, it has the function of
automatically reclosing lock. For other switching devices, some like ring
primary unit switchgear are mostly applicable for 36kv switchgear for the
moderate voltage.
Much more intelligent
Intelligent transformer substation( Intelligent
Switchgear) has characteristics of informatization, automatization and
interaction. Intelligence mainly embodies in two elements, intelligent device
and intelligently sophisticated application. Intelligent device realizes
organic separation of one-time device and intelligent component. To be exact,
intelligent device assists one-time device to finish transmitting and
distributing electric energy at meanwhile of measuring, controlling, sustaining
and metering.
Much more secure and green
Transformer substation technical advance
ensures efficiency and precision in data transmitting which promotes power
supply stability and ensures energy grid much more steady operation. With
additional adaptation, modularization and standardization in intelligence
technologies, the information collecting, transmitting and processing become
much more regular, successfully supporting ??one-whole regulation and one-whole
operation?ˉ. Detection measures like Integration video linkage and state
analysis well make sure pr¨|cised sequential control and unattended operation.
Also, it achieves energy saving and emission reduction by advertising device
resource utility ratio and stable power supply(Power Distribution
Box Manufacturer).
