Product Introduction
General
The so-called "ring network cabinet" means that each distribution branch is equipped with a switch cabinet (outgoing switch cabinet), and the busbar of this switch cabinet is also a part of the ring trunk. In other words, the ring trunk line is composed of the bus bars of each outlet cabinet. Each outlet cabinet is called a "ring network cabinet". In fact, if you take out a ring network cabinet alone, you can't see the meaning of "ring network".
Protection device
On the basis of many years of application experience of domestic
and foreign counterparts in the microcomputer protection device of
the ring network cabinet, combined with the actual characteristics
of the domestic integrated automation system, the development of a
high-tech power automation product integrating protection,
monitoring, control, communication and other functions is a
composition Ideal electrical unit for intelligent switchgear. The
product has a built-in protection library composed of more than 20
standard protection programs, which has a complete and powerful
collection function of the voltage, current analog quantity and
switch quantity of the primary equipment (current measurement is
realized through the protection CT).
Microcomputer protection
Since the ring main unit is subjected to high voltage, a protection
device is required to protect the ring main unit. The use of
microcomputer protection devices in the ring main unit is becoming
more and more popular. Due to the small size and low cost of the
ring main unit, it is necessary to have a cost-effective and
practical microcomputer protection device.
