Structural features
KYN28A-24(Z) switch cabinet is composed of two parts: fixed cabinet body and extraction parts (hereinafter referred to as handcart). According to the function of the electrical equipment in the cabinet, the cabinet body is divided into four different functional units with metal partitions. (as shown in the figure) bus room a, cable room B, relay instrument room c, circuit breaker room d. The shell of the cabinet and the partition between each functional unit are all made of 2mm aluminum-zinc coated plate bent and bolted.
The switch cabinet is equipped with a charged display device for detecting the operation of the primary circuit. The device consists of a high-voltage sensor and a display. The protection grade of the switch cabinet enclosure is IP4X, and the protection grade when the circuit breaker chamber door is opened is IP2X.
The switch cabinet considers the influence of the internal fault arc of the switch cabinet from the structure, and has passed the internal fault arc effect test and condensation pollution test, which can effectively ensure the safety of operators and equipment.
