1、Brief Introduction
on Transformer Substation
Transformer substation is among the power
provide facilities, a location what's used for voltage alter. the voltage must
be risen in order to transmit the energy of electric power to a distant place,
and then decrease the voltage according to the need of customs when close to
the user , this function is completed by converting station , whose main
substation gear is switchgear and transformer. The ring primary unit switchgear
is equipped with a vacuum load switch, spring operating mechanisms that can
manual operation, but additionally electric operation.
Based on the various size, little
substation also referred to as for substation, energy distribution space and so
on. Substation voltages transforms and distribute electricity.
two. The fundamental Type 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 present (with a known frequency) have a
tendency to become one from the coils, and also the other coil will induce
exactly 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 power supply, double- power provide or terminal power
supply systems as HV power distribution measuring, compensation manage and
protection equipments, What's totally sealed and insulated. The HV load switch,
HV fuse may be placed in transformer oil. These components may be separated
from transformer physique or enclosed within one compartment with transformer
physique. The material of this really is qualified cold-rolled steel plates
that have high bending, compact resistance and ensile strength. The surface has
high anti-corrosion property with static powder coating processing.
four. Combined
SubstationCombined substation is really a type of equipment consists of
switch, transformers, low voltage apparatus with the features as followings:
1) Series, modular style.
2) Substation has the advantages of compact
structure, small volume, small occupying area, short building period, much less
investment.
3) Superb temperature, humidity manage and
atmosphere monitoring system, reliable equipment operation environment.
four) Convenient in and out cable way.
5) Transformer manufactures will provide
shell with environmentally friendly materials and top quality heat insulation
sandwich board for users to choose.
Digital substation is essential for the
technology of automatic substation, which has the milestone significance. and
can have a far-reaching influence on the numerous aspects from the substation
automatic method. Three primary feature of digital substation is "a
intelligent equipment, secondary equipment network, in line with the IEC61850
standard”, that is to say, all the info will probably be digital, varies of
devices could share a unified information platform. Substantial improvement
will be made in method reliability, economy and maintence.(Europe Type
Substation)
