Product Description

Product Description
KYN28A-24 (z) series armored removable AC metal switchgear is a power distribution equipment for 20kV three-phase AC 50 (60) Hz single bus and single bus sectional system.
It is mainly used in power plants, small and medium-sized generator power transmission, industrial and mining enterprises power distribution and secondary substation of power systems for power receiving, power transmission and large high-voltage motor starting, etc., for control protection and monitoring. It can be equipped with 6-point or 9-point on-line temperature measurement technology, which can realize remote control of the electric operation of grounding switch, electric swing in and out of circuit breaker handcart and internal fault arc protection of switch cabinet, and realize intelligent control of switch cabinet.
The switch equipment has the "five prevention" interlocking function of preventing pushing and pulling the circuit breaker handcart with load, closing the circuit breaker by mistake, closing the circuit breaker when the grounding switch is in the closed position, entering the live compartment by mistake, and closing the grounding switch by mistake when the grounding switch is live. It can be used with VS1-24 vacuum circuit breaker developed by our company, which is a kind of superior power distribution device.
This product conforms to GB3906 "3-35kv AC metal enclosed switchgear" and IEC62271-200 "rated voltage above 1kV and below 52kv AC metal enclosed switchgear and control equipment"

Product technical parameters and structure




Product features 
1:It has perfect mechanical and electrical double locking and anti error operation function.
2:The cabinet can be flexibly equipped with VS1, VYG, VD4, VN2 and other vacuum circuit breakers.
3:The roof part adopts ventilation design, that is, it can meet the need of dust prevention and no need to consider the problem of pressure relief.
4:Cabinet use: single axis, double shaft and so on, to meet different requirements.
5:Using Aluminum-zinc composite flanging process, application of flat screw installation, flexible use, convenient, simple and practical, good performance.
6:KYN28-24 in the high voltage electrical equipment quality supervision and inspection center through the full tank type experiment, its design and manufacture fully meet the requirements of GB, DC, IEC standards.



Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
