Description

KYN28A 6.3KV waterproof sealed distribution box

KYN28A-12 series switchgear is suitable for the complete set of power distribution devices of voltage 3-12KV, three-phase AC 50Hz single bus and single bus section system. Mainly used in power plants, substations, industrial and mining enterprises and high-rise buildings, as receiving and distributing electric energy and controlling, protecting and monitoring circuits

1.Service environment

The ambient air temperature : -5°C ~ +40°C;

Daily average temperature(Within 24h): ≤+35℃
Altitude:≤1000m;
Relative humidity: within 24h, daily average value ≤ 95% , daily average vapor pressure≤ 2.2KPa;
monthly average value ≤ 90%, monthly average vapor pressure≤ 1.8KPa
Ambient air is not significantly polluted by dust, smoke, corrosive and / or flammable gas, vapor or salt contamination.

2. Structure

2.1 Enclosure
Switchgear enclosure adopts imported aluminum zinc steel sheet by CNC machine tool processing, and use multi-fold workmanship strong oxidation resistance and corrosion resistance, light weight, strong mechanism strength.
Enclosure with degree of protection IP4X is divided into four separated compartments, when the door opens the compartment and circuit breakers the degree of protection is IP2X

2.2 Trolley(VCB)
The trolley frame assembled with thin steer after CNC machine tool. The trolley co-ordinated with the switchgear as to make the mechanical interlock safe and reliable. Trolley with the same specification are interchangeable.
Circuit breaker trolley is equipped with vacuum circuit breaker and other auxiliary equipment, the VCB can be circuit VD4 of ABB or VT19 manufactured by ourselves. It can be reliably locked in disconnected position, test position to ensure reliable interlock.

2.3 Busbar component
The branch bus is connected to the static contact box and main busbar without other supports. Main busbar is separated and fixed by the bushing in case of arc failure.
This construction can effectively prevent the accident spreading to other cabinets.

2.4 Instrument cabinet
All kinds of switch, status-indicator and measuring instrument etc could be mounted on the door of the instrument. Protective relay, secondary wire, terminal and air switch, low-voltage fuses, etc, are equipped inside the instrument cabinet.

2.5 Fail- safe interlock
There is a "anti-5" mechanical latch between the disconnector, VCB and panel door, a reliable measurement to prevent from mis-operation, convenient and safe maintenance, flexible operation.

3.External Dimension And Weight

Height H(mm) 2300(2200)
Width w(mm)	Rated current of branch busbar is up to 1250A Short time withstand current is 40KA	800
	Rated current of branch busbar is up to 1600A and above	1000
Depth d(mm)	Cable incoming and outgoing	1500
	Overhead incoming and outgoing feeder	1660
Weight(kg) 700-1200
