KYN28柜是一种高压开关柜，具体信息如下：应用范围：KYN28柜适用于三相交流50Hz单母线和双母线分段系统的户内成套配电设备。适用于额定电压3-12kV电网的发电厂、变电站、工矿企业。它用于接收和分配电能，以及控制、保护和监控电路。结构特点：The KYN28 cabinet consists of a fixed cabinet body and a movable vacuum circuit breaker handcart. The cabinet body is divided into four small chambers: busbar chamber, circuit breaker chamber, cable chamber, and low-voltage chamber.
The cabinet structure is made of aluminum zinc coated plate processed by CNC machine using multiple bending processes and bolted together; All operations are carried out with the cabinet door closed; High protection level, which can prevent the invasion of debris and pests; Simple and effective "five prevention" locking to prevent misoperation.
Can be equipped with VS1 and VD4 vacuum circuit breakers; Replacing the circuit breaker is simple, and the handcart has good interchangeability performance; Reliable wall installation and front maintenance of cabinets to reduce floor space; The cable room has ample space and can connect multiple cables; Heaters can be installed separately in the circuit breaker room and cable room to prevent condensation and corrosion.技术参数：Rated voltage: 3.6kV~12kV.
