Many people are confused about the difference of
power transformer and distribution transformer. In fact, there are many difference
between them, and this article will help you fully understand their differences.
Rural power grid transformation and upgrading
refers to the new construction of rural power grid facilities such as substations
and lines, as well as the local or overall local or remote construction, capacity
increase and equipment replacement of existing rural power grid facilities.
Application Reason of Step Voltage Regulators:
The voltage on modern distribution circuits is becoming increasing difficult to
manage. New distributed energy resources, such as solar, combined with the growth of
sophisticated loads creates voltage challenges on distribution network systems.
Existing voltage control devices cannot maintain a consistent voltage profile.
The indoor SF6 load break switch is a kind of
switching device with a simple arc extinguishing device which is installed in ring
main unit and switchgear. It can be used for switching and breaking load current and
overload current.
RPS type SF6 load break switch (SF6 LBS) is a
pole-mounted load beaker switch independently developed by Wenzhou Rockwill Electric
Co., Ltd. It is suitable for load current, overload current breaking and closing in
a voltage range of 11~40.5kV distribution network ,also can automatically isolate
faulty distribution lines.
At present, most enterprises are connected to the
power grid by using 33kV box type prefabricated compact substation built by
themselves. Therefore, the quality control of box type substation is very important,
This not only affects the reliability of power supply, but also has a great impact
on the normal operation and economic benefits of the enterprise.
Ring Main Unit: indoor ac high voltage gas
insulated metal-enclosed switchgear (RMU) is a new generation of switchgear
equipment, the main switch can either use permanent magnetic vacuum circuit breaker
or spring mechanism vacuum circuit breaker.
Common faults and solutions of LV / MV
switchgear. Including reject closing and opening, abnormal sound, locking failure,
light out, remote control failure, indicator failure, etc.
Step Voltage Regulator - A device which will
provide a constant voltage output under varying input voltages and load currents.
Regulating +10% voltage and –10% voltage. Including auto transformer, load tap
changer, voltage regulator control.
three-phase current unbalance in transformer will
cause Influences on distribution transformers, high-voltage lines, distribution
panel, low-voltage lines and users.
