High voltage switch cabinet Detailed description of KYN28A-12 central cabinet shell:
1、 Product introduction:
KYN28-12 (Z) (GZS1) armored removable AC metal enclosed switchgear is a complete indoor power distribution device with rated voltage of 3.6~12kV three-phase AC 50Hz. It is used for power transmission in power plants, power industry systems and power receiving and distribution in substations of industrial and mining enterprises, and can also be used to frequently start high voltage Motor Etc.
The switch cabinet can meet the requirements of GB3906, DL404, IEC-298 and other standards, and can prevent misoperation of the circuit breaker and load pushing handle "Five prevention" functions, such as preventing electrification from closing the grounding switch, preventing power transmission when the grounding switch is in the grounding position, and preventing entering the electrification interval by mistake.
