KYN28A (P/V-1 2) Series

AC metal-enclosed switchgear
KYN28A (P/V-12) AC metal-enclosed switchgear, also known as mid-set switchgear (full name: armored removable AC metal-enclosed switchgear), is a three-phase AC 50Hz indoor assembled power distribution equipment, which is used to receive and distribute 3.6-12 kV network electrical energy and implement control protection and monitoring of the circuit. It is widely used to implement control, protection and detection in the power generation of power plants, small and medium-sized generators, distribution of industrial and mining enterprises and institutions, power distribution and generation of secondary substation of power system, start-up of large high-voltage motors, etc., which can be equipped with ABB's VD4 vacuum circuit breaker, can also be equipped with VS1 vacuum circuit breaker, meeting the relevant standards of GB 3906, DL403, DL404, IEC-298, etc.

Product Features

Five Interlocks, Safe and Reliable


● It has "five functions" to prevent misoperation of circuit breaker, to prevent pushing and pulling trolley with load, to prevent closing grounding switch with electricity, to prevent grounding switch from powering-on in grounding position and to prevent false entry into live interval.


Reasonable Structure, and High-end Materials


● The switchgear is divided into three independent compartments, and the top of each compartment is equipped with a pressure relief device; when an internal fault occurs, the air pressure inside the high-pressure chamber rises, and the high-pressure gas will be released through the pressure relief device.
● The shell and partition of the switchgear are made of high-quality zinc-plated steel plates which are bent and bolted by CNC machining center, with strong anti-oxidation and corrosion resistance, high steel and mechanical strength.
● Adjacent switchgear is separated by their respective side plates and partitions, and there is still an air buffer layer after splicing the cabinet, which can prevent the switchgear from being melted by the fault arc


Brand Unification for Maintenance


● P/V-12 adopts the technical design of Shanghai General Electric Company, and the cabinet is equipped with VB2-12 solid-sealed trolley vacuum circuit breaker, the cabinet and the circuit breaker are of the same brand.
