Application
The XGN15-12 series AC metal ring main switchgear is applicable to the electric power system with the AC frequency of 50Hz and voltage of 12KV and it is widely applied to the industrial and civilian cable ring main unit as well as power supply terminal.
It is especially applied to the following places such as power distribution of the urban residential courtyard, small secondary substation, switch station, case type substation, factory, shopping mall, airport, subway, wind power generation, hospital, gym, railway and tunnel etc.
Structure of Ring Main Unit of XGN15-12 II and III Types
The AC metal main unit of XGN15-12 II and III types is composed of the following four parts:
The whole switch cabinet of XGN15-12 II and III types can be divided into the upper and lower units. Its upper unit includes the bus room, load switch, operating mechanism room and low pressure room, which composes of a whole unit with the cable room of the upper unit or separated. It can be safely and easily installed on the equipment in the upper unit for maintenance and transformation. The whole upper unit can be replaced when necessary.
Summary
The KYN28-12 steel-clad movable-type AC metal switchgear (hereinafter referred to as switch cabinet) is applicable to the complete power distribution device of the single bus section system with the three-phase AC frequency of 50Hz and voltage of 3.6~12kV to accept and distribute the network electric energy as well as control, protection and monitor the circuit. It is widely applied to the industries such as electric power, metallurgy, petrochemical industry and urban construction and so on.

Basic Structure
1.This switch cabinet is mainly composed of two parts, including the cabinet and movable part (handcart for short). The protection grade of the external hub is IP4X, while the protection grade of all isolation rooms is IP2X, having the plans such as overhead incoming and outgoing, cable incoming and outgoing and other functions. The installation, debugging and maintenance of the switch cabinet can be carried out in front, thus the installation can be carried out in front and rear of the cabinet.
2.For the boundary dimension and weight, please see the list and Figure 1.
This switch cabinet is made of the Al-Zin alloy plate and machined by the CNC tool. The multiple folding is used. It has good appearance, high precision, high intensity, corrosion resistance and oxidization resistance.
Handcart
1.According to different applications, the handcarts can be divided into the breaker handcart, voltage transformer handcart, metering handcart and isolating handcart. The handcarts with the same specification can be freely exchanged. The handcart has the test (isolation) position and operating position in the cabinet and each position has the positioning device to ensure reliable interlocking. When the handcart should be removed out from the cabinet, it can be easily removed out with a specific transfer cart for various inspections and maintenances.
2.After the breaker handcart is pushed into the cabinet with a specific transfer cart, it is first positioned at the test (isolation) position. After the handcart is locked in the cabinet, the mechanism can be swayed and pushed. The handcar is pushed to the operating position.
