KYT8 ( KYN28A ) - 24 Safety Electrical Metal Clad Switchgear Metering Cabinet

KYT8 ( KYN28A ) - 24 Safety Electrical Metal Clad Switchgear Metering Cabinet​

Overview

KYN28-24 type armored remove AC metal- switch cabinet is three -phase AC50Hz,rated voltage 24KV indoor power distribution equipment .As power plants ,substations ,industrial &mining enterprises to accept amd distribute of electric energy to control ,protect and monitor, circuit , ect. Can also be used to control the place of frequent operation .

1. Service condition

1. Altitude:<=1000m
2. Ambient air temperature:-15℃~ +40℃(-25℃ is allowed to transport and storage )；
3. Relavent humidity:daily average humidity≤95%
4. Monthly average humidity<=90%
5. Suitable for condensation and Class II polluted environments
6. Without corrosive, flammable gas and steam and no regular severe shock
7. For special service condition, need to negotiable with manufacture
8. The seismic intensity shall not exceed Grade 8

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 comp artments, 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
