Our company can produce this product with a voltage class range of 1-40.5kV and below.The KYN series switchgear is an armored withdrawable AC metal-enclosed switchgear. It is suitable for a three-phase AC 50Hz power system, used for receiving and distributing electrical energy, and implementing control, protection, and monitoring of the circuit.
The main models are KYN28A-12, KYN28A-24, and KYN61-40.5. It can be equipped with various indoor vacuum circuit breakers and can be installed with microcomputer protection as a combined electrical appliance to achieve remote measurement,remote control, remote signaling, and unattended operation. It is mainly used for power transmission of small and medium-sized generators in power plants, power distribution in industrial and mining enterprises, station service transformers in the power system,power distribution in high-rise commercial centers and residential areas, for implementing control, protection, and monitoring.
For the KYN28A-12 and KYN28A-24 series switchgear, the switchgear as a whole is composed of two major parts: the cabinet body and the center-mounted withdrawable components (i.e., the circuit breaker carriages). The cabinet body is divided into four separate compartments. The protection level of the outer shell is IP4X, and the protection level when the doors ofeach compartment and the circuit breaker compartment are open is IP2X.
It has overhead incoming and outgoing line, cable incoming and outgoing line,and other functional schemes. After being arranged and combined, it forms a complete set of power distribution system equipment. This switchgear can be installed,debugged, and maintained from the front. Therefore, it can be installed back-to-back, in double rows, and against the wall, which improves the safety and flexibility of the switchgear and reduces the occupied area.
