Product Description

Product Description

KYN28-12 metal armored central switchgear is a complete set of power distribution device for 3.6~12KV three-phase AC 50Hz single bus sectional system. It is mainly used for power transmission of power plants, small and medium-sized generators, power distribution of industrial and mining enterprises and institutions, as well as power reception and power transmission of secondary substations of power systems, and starting of large high-voltage motors, etc., for control, protection and monitoring purposes. The switchgear meets IEC298, GB39 06 and other standards, it has the interlock function to prevent the push-pull circuit breaker handcart under load, prevent entering the compartment with point by mistake, and prevent the grounding switch from being mistakenly closed when electrified. It is a power distribution device with superior performance. The shell is completely metal armored, the assembled structure, the combination scheme is wide, the protection level of the shell can reach IP4X, and the compartment and circuit breaker room door can reach IP2X after opening. The cabinet is made of imported aluminum-zinc-coated thin steel plates, processed by CNC machine tools, and adopts multiple hemming processes. It is connected with rivet nuts and high-strength bolts. High precision, corrosion resistance, light weight, high strength, strong general performance of parts and other outstanding advantages. According to the characteristics of various protection objects, in addition to the traditional relay protection device, it can also be equipped with a special microcomputer protection device. The device integrates various protection functions and has the characteristics of small size, strong function and wide setting range. It can be equipped with VS1 vacuum circuit breaker, original VD4 series vacuum circuit breaker from ABB, 3AH series vacuum circuit breaker from Siemens, and YV series vacuum circuit breaker from Hitachi.
