Product Description:

KYN28 A-24 Air-Insulated Metal-Clad Withdrawable Switchgear (hereinafter referred to as KYN28A switchgear or switchgear) is a complete set of distribution equipment for 15~24kV three-phase AC single busbar and single busbar segmented system. It is mainly used in power plants, substations, industrial and mining enterprises, and high-rise buildings for power transformation and distribution, as well as for receiving and distributing electrical energy, controlling, protecting, and monitoring lines.

The KYN28A switchgear meets the requirements of IEC298, GB3906 and other standards, and has interlocking functions to prevent pushing-pulling circuit breaker handcart with load, prevent accidental opening and closing of the circuit breaker, prevent closing of the circuit breaker when the earthing switch is in the closed position, prevent accidental entry into the live compartment, and prevent accidental closing of the earthing switch when charged.

KYN28A switchgear is a mid mounted, miniaturized, metal-clad, and air insulated switchgear. According to the different purposes of the mid-mounted handcart, it can be divided into: circuit breaker handcart, contactor handcart, load switch handcart, isolation handcart, PT handcart, metering handcart, fuse handcart, lower PT handcart, lower lightning arrester handcart, etc. The main switch can be equipped with vacuum circuit breakers from domestic or foreign manufacturers such as VS1 (VTD6), VT19, VD4, etc., which is actually a high-performance distribution device.

The design and manufacturing of KYN28 switchgear comply with the following standards:

GB/T3906 3.6kV~40.5kV AC metal-clad switchgear and control equipment

GB/T11022 Common technical requirements for high-voltage switchgear and control equipment standards

GB/T1984 High voltage AC circuit breaker

DL/T404 3.6kV~40.5kV AC metal-clad switchgear and control equipment

IEC62271-200 AC metal-clad switchgear and control equipment with rated voltage of 1kV and above & 52kV and below

IEC62271-100 High voltage switchgear and control device - Part 100: AC current circuit breaker
