1、Brief Introduction
on Transformer Substation
Transformer substation is among the energy
supply facilities, a location what's used for voltage change. the voltage must
be risen in order to transmit the energy of electric power to a distant
location, and then reduce the voltage according to the need of customs when
near the user , this function is completed by converting station , whose
primary substation gear is switchgear and transformer. The ring main unit
switchgear is equipped having a vacuum load switch, spring operating mechanisms
that can manual operation, but also electric operation.
Based on the different size, little
substation also known as for substation, power distribution space and so on.
Substation voltages transforms and distribute electricity.
two. The basic Kind of Transformer
The fundamental type of transformer consists
of two groups of coils and be with each other with one another by inductance.
When an alternating current (with a recognized frequency) tend to be one of the
coils, and also the other coil will induce the same frequency voltage, and
induced voltage depends on the two coil coupling and magnetic exchange chain
level.
three. America
Type Substation
American kind substation enclosure series
is utilized in 10kv loop net power provide, double- energy supply or terminal
energy supply systems as HV power distribution measuring, compensation control
and protection equipments, What is totally sealed and insulated. The HV load
switch, HV fuse can be placed in transformer oil. These elements can be
separated from transformer body or enclosed inside 1 compartment with
transformer physique. The material of this is certified cold-rolled steel
plates which have high bending, compact resistance and ensile strength. The
surface has higher anti-corrosion home with static powder coating processing.
4. Combined
SubstationCombined substation is really a type of gear consists of switch,
transformers, low voltage apparatus with the attributes as followings:
1) Series, modular style.
2) Substation has the benefits of compact
structure, small volume, small occupying region, brief building period, less
investment.
three) Excellent temperature, humidity
control and atmosphere monitoring system, reliable gear operation environment.
four) Convenient in and out cable way.
5) Transformer manufactures will offer
shell with environmentally friendly supplies and high quality heat insulation
sandwich board for users to select.
Digital substation is important for the
technologies of automatic substation, which has the milestone significance. and
can possess a far-reaching impact around the various aspects from the
substation automatic system. 3 main feature of digital substation is "a
intelligent equipment, secondary equipment network, in line using the IEC61850
standard”, that is to say, all of the info will be digital, varies of devices
could share a unified info platform. Substantial improvement will be produced
in method reliability, economy and maintence.(Europe Type
