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.
