1、Brief Introduction
on Transformer Substation
Transformer substation is among the energy
supply facilities, a location what is used for voltage change. the voltage must
be risen to be able to transmit the energy of electric power to a distant
place, and then decrease the voltage based on the need of customs when close to
the user , this function is completed by converting station , whose primary
substation equipment is switchgear and transformer. The ring main unit
switchgear is equipped with a vacuum load switch, spring operating mechanisms
that can manual operation, but additionally electric operation.
According to the various size, small
substation also referred to as for substation, energy distribution room and so
on. Substation voltages transforms and distribute electrical energy.
two. The basic Kind of Transformer
The basic kind of transformer consists of
two groups of coils and be together with one another by inductance. When an
alternating present (having a recognized frequency) tend to become 1 of the
coils, and the other coil will induce the same frequency voltage, and induced
voltage depends on the two coil coupling and magnetic exchange chain level.
American kind substation enclosure series
is used in 10kv loop net energy provide, double- energy supply or terminal
power supply systems as HV energy distribution measuring, compensation manage
and protection equipments, What is totally sealed and insulated. The HV load
switch, HV fuse may be placed in transformer oil. These components can be
separated from transformer body or enclosed inside one compartment with
transformer body. The material of this really is certified cold-rolled steel
plates which have higher bending, compact resistance and ensile strength. The
surface has higher anti-corrosion property with static powder coating
processing.
4. Combined
SubstationCombined substation is a kind of equipment 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, short construction period,
less investment.
three) Excellent temperature, humidity
control and environment monitoring system, dependable equipment operation
atmosphere.
four) Handy in and out cable way.
5) Transformer manufactures will offer
shell with environmentally friendly supplies and high quality heat insulation
sandwich board for customers to select.
Digital substation is essential for the
technology of automatic substation, which has the milestone significance. and
can possess a far-reaching impact on the various aspects of the substation
automatic system. 3 primary function of digital substation is "a
intelligent equipment, secondary gear network, in line with the IEC61850
standard”, that is to say, all the information will be digital, varies of
devices could share a unified information platform. Substantial improvement
will probably be made in system reliability, economy and maintence.(Europe Type
