KYN28A-12 (Z) indoor armored removable AC metal-enclosed switchgear is a medium-voltage power distribution switchgear initiated by Xi'an Senyuan. It is suitable for three-phase AC 50Hz, 7.2~12kV single bus and single bus segmented power system, used for receiving and distributing electric energy, and controlling, protecting and monitoring the circuit. The equipment fully meets the requirements of "Electrical Five Preventions", and has passed the internal fault arcing test and condensation pollution test.
It is widely used in power plants, small and medium-sized generators and transmissions, power distribution in industrial and mining enterprises, and secondary substations in power systems, as well as power transmission and large-scale high-voltage motor starting, etc., for control, protection, and monitoring.
The KYN28A-12 series switchgear mechanism as a whole is composed of a cabinet and a central withdrawable part. The cabinet partition is divided into five independent compartments. The enclosure protection level is IP4X, and the protection level of each compartment is IP2X. The equipment is equipped with a VS1 vacuum circuit breaker or fixed load switch in the handcart room, which can be installed, debugged and maintained from the front, so it can be back-to-back formed in a double arrangement and installed against the wall, which improves the safety and flexibility of the switchgear and reduces It covers an area.
