KYN28A-12 Indoor Metal Clad 6.6KV Switchgear LV MCC Panel
General
KYN28 indoor metal-clad switchgear is a complete power distribution
device for 3.6~24kV,3-phase AC50/60Hz,single-bus, and single-bus
sectionalized system. It is mainly used for power transmission of
middle/small generators in power plants; power
receiving, transmission for substations in power distribution and
power system of factories, mines and enterprises, and starting of
large high-voltage motor, etc., so as to control, protect and
monitor the system. The switchgear meets IEC, GB3906-91.In
addition, to be used with domestic VS1 vacuum circuit breaker, it
can also be used with VD4 from ABB, 3AH5 from Siemens domestic
ZN65A, and VB2 from GE, etc., it is truly a power distribution
device with good performance.
In order to meet the requirement for wall mounting and front-end
maintenance, the switchgear is equipped with a special current
transformer, so that the operator can maintain and inspect it in
front of the cubicle.
Working environment
1. Temperature: -25℃~+40℃
2. Humidity: Monthly 95%; Daily 90%.
3. Altitude: less than 2500m
4. Ambient air not apparently polluted by corrosive and flammable
gas, vapor, etc.
5. No frequent violent shake
Fully type-tested
The switchgear has undergone all the tests required by the
international (IEC) Standards. Each switchgear unit is subjected to
routine tests in the factory before delivery. These tests are
intended to provide a functional check of the switchgear based on
the specific characteristics of each installation.
Cabinet parameter editing
The cabinet structure is made of aluminum-zinc-coated sheets, which
are bolted and processed by CNC machine tools using multiple
bending processes;
All operations are carried out with the cabinet door closed;
The protection level is high, which can prevent the intrusion of
debris and insect pests;
Simple and effective "five prevention" lockout to prevent
misoperation;
Can be equipped with VS1 and VD4 vacuum circuit breakers;
It is easy to replace the circuit breaker, and the handcart
interchangeability is good;
Reliable wall installation and front maintenance of the cabinet
reduce the floor space;
The cable room has ample space and can connect multiple cables;
The circuit breaker room and the cable room can be equipped with
heaters respectively to prevent condensation and corrosion.
