Product Description

High voltage  electrical panel for substation model KYN28-12


                                KYN28 12kV Medium Voltage draw out Switchgear With Circuit Breaker 0





This equipment is indoor metal armoring with drawable switchgear (hereafter refer to as switchgear). With 3.6~12kv three phase AC 50Hz single bus bar and the single bus bar subsection system's complete electricity distribution equipment is used in the power plant, small and medium-sized generator power transmission, industry and mining business power distribution as well as electrical industry system's second transformer substation's electric take-over, power transmission and large-scale high pressure motor starting and so on. The purpose is to control, protect and monitor. This switch equipment is up to the standard of IEC298, GB3906 and can prevent the charge from pushing and pulling the breaker, from opening and closing the breaker, from insulation withelectricity by mistaken, from earthed switch closing the breaker, from opening the switch's interlock when it with electricity mistakenly. It can not only use with VS1 vacuum circuit breaker, but with ABB Corporation's VD4 vacuum circuit breaker. It is indeed a kind of power distribution equipment with superior performance


Service conditions
a. Ambient temperature: Maximum temperature:+40℃ Minimum temperature: -15℃
b. Ambient humidity: Daily average RH no more than 95%;Monthly average RH no more than 90%
c. Altitude no higher than 2500m;
d. The air around without any pollution of duty,smoke,ercode or flammable air,steam or salty fog;



The switch cabinet is metal-clad. Its structure design accords with the standards GB3906-91, IEC298, DL404 and DL402. The crust structure is made of steel plates by means of bending and welding, which are joined by bolts. The hand buggy panel is the door of cabinet. The bosom of switch cabinet is divided into a breaker chamber, a main bus bar chamber, a cable chamber and a relay chamber by metal partitions. The degree of protection of the entire crust and compartments is IP2X equally. All the metal structures are connected to ground reliably. All the compartments of main circuit system have pressure release channels for independent exhaust.
