Chinese type box change is also known as preassembled
substation (China change), usually referred to as the box change,
"China change", generally refers to the Chinese type box change,
it is a special type of preassembled substation, with its unique
characteristics and advantages. Chinese-type box change
compact structure, miniaturization, Chinese-type box change to
cancel the transformer room, making the overall floor area is
smaller than the European box change, the same capacity of the
product floor area is only about 58% of the European box change.
The transformer body is mostly oil-immersed transformer, and is
directly hung outside the box transformer shell, which further
saves space.
Chinese type transformer is safe and reliable:
Busbar connection is selected to connect the high-voltage switch
to the transformer, which solves the operation safety problem
caused by cable connection.
A grounding switch, lightning arrester and other safety devices
are provided, and a mechanical interlock is set between the
grounding switch and the main switch to ensure personal safety
during maintenance.The characteristics of the Chinese box change:
The isolation knife of the high voltage switch and the arc
extinguishing chamber and the fuse are designed to be placed in
separate chambers, which realizes the performance of single
maintenance without stopping other equipment.
The heat sink on the transformer is installed in open mode to
realize natural ventilation and reduce the problem of unreliable
fan performance caused by forced ventilation.
The Chinese box becomes environmental protection and
energy saving:
The transformer has good heat dissipation effect and reduces the
loss of electric energy caused by overheating.
The overall design of the transformer takes into account dust, rain
and snow, sand and dust and other environmental factors,
suitable for long-term outdoor use.
The intelligent design of the Chinese box:
The whole station adopts intelligent design, and the protection
system adopts the substation microcomputer integrated automation device, which can realize the "four remote" function
(telemetry, remote communication, remote control, remote
adjustment).
The use of Chinese box change
It is especially suitable for power distribution projects away from
residential areas, wind power generation projects, wind power
and photovoltaic projects with large installed capacity of single
box transformer. In these application scenarios, Huashi
Transformer can give full play to its advantages of compact
structure, safety and reliability, convenient maintenance, and
provide a strong guarantee for the stable operation of the power
system.
China type box variable price
The variable price of Chinese box depends on its different
configuration and capacity size, the capacity is basically above
2000kva, and the maximum capacity of a single unit is about
10000kva.
SummaryAs a special type of preassembled substation, Chinese type
transformer has been widely used in power system because of its
compact structure, safety and reliability, convenient maintenance,
environmental protection and energy saving and intelligent
design. Especially in the field of new energy such as wind power
and photovoltaic, the change of Chinese-type box has shown its
unique advantages and value.
