KYN28A-12 armored removable metal enclosed switchgear
KYN28 switchgear is composed of two parts: fixed cabinet body and outlet J (I .e. handcart). According to the function of electrical equipment in the cabinet, the cabinet body is divided into four different functional units with metal partitions: bus room 8. main switch room B, cable room C and instrument room D. In order to facilitate the construction of additional small busbar room E. The shell of the cabinet and the partitions of each functional unit are formed by bending and forming aluminum-zinc coated plates and then bolted.
The extractable part of the switchgear can be equipped with vacuum circuit breaker handcart, contactor handcart, metering handcart, PT handcart, isolation handcart, fuse handcart, grounding handcart, electric inspection handcart, lightning arrester handcart and other equipment, with complete specifications and varieties.
The switchgear adopts a unique and innovative design, the overhead incoming and outgoing cable does not need to be attached to the cabinet, and the 11 cabinet body shape remains unchanged, which is convenient for flexible combination of various primary system schemes and saves the space occupied by the distribution room.
Each chamber of the switchgear is provided with an independent pressure relief channel, which can effectively ensure the safety of the operator's body and equipment.
The installation and debugging of the switchgear can be carried out at the same time in front of the cabinet and behind the cabinet, so the switch cabinet can be installed away from the wall or against the wall.
KYN28 switchgear can be widely used in public utilities and power stations (such as power plants, substations, switching stations, etc.) industrial systems (such as steel, metallurgy, petroleum, chemical, petroleum, paper, cement, etc.) Transportation (such as airports, ports, subways, etc.), civil power distribution (such as hospitals, residences, infrastructure).

- KYN28 switchgear is 3 ~ 10kV three-phase AC 50HZ single bus armored metal enclosed switchgear, air insulated, suitable for indoor installation.
- The structure of the switchgear is a single-layer, each compartment is isolated from each other by a metal partition into separate small chambers, and each component of the same compartment uses air as an insulating medium.
- The switchgear is equipped with perfect five-prevention interlocking function, equipment maintenance and service can be carried out in front of the cabinet, and the main switch and grounding switch can be operated behind closed doors in front of the cabinet.
- The switchgear can be equipped with a variety of commonly used vacuum circuit breaker handcart, can also be equipped with vacuum contactor handcart, the same type of main switch can be interchanged. In addition, the switching equipment can also be installed with a fixed load switch, the main switch is flexible and has a wide range of applications.
