Structural features:

Kyn28-12 metal-armored high voltage switchgear adopts intermediate structure, which saves about 50% of the circuit breaker room and facilitates cable installation.The primary circuit switch is installed on the kola car, which is easy to be interchanged with the size trolley.Due to the armored construction, the components are installed in an earthing compartment separated by a metal partition.The protection grade of switch cabinet is IP4X.Vacuum circuit breaker with permanent magnet mechanism can be equipped with vacuum circuit breaker VS1, VD4, ZN63, etc.The switch cabinet can be connected with the protection system, with the function of "four remote control", realizing the automation of the distribution station.

1. The cabinet shell and baffle board of switch cabinet are made of aluminum-zinc steel sheet after CNC machining and bending, so the assembled switch cabinet can maintain the unity in size.Aluminum-zinc coated steel plate has strong anti-corrosion and anti-oxidation effect, and has higher mechanical strength than the same steel plate.The switch is divided into handcart room, bus room, cable room and relay meter room by partition board.The door of switch cabinet USES electrostatic spray to make its surface has the advantages of anti-collision, anti-corrosion, beautiful appearance (color can be determined by the user).

2. Handcart frame is made of aluminum-zinc coated steel plate after being riveted and welded by CNC machine tools: according to the purpose, handcart can be divided into circuit breaker handcart, voltage transformer handcart, isolation handcart, metering handcart, etc. Handcart of the same specification can be easily exchanged.Handcart in the cabinet from the limited position, test position and working position, each position is equipped with positioning device, in order to ensure that the handcart in the above position can not be moved arbitrarily, and the handcart must be moved to remove the interlock

3. The bus bar leads from one switch cabinet to another switch cabinet and is fixed by the branch bus bar and the static contact box.The flat branch busbar is connected to the static contact box and the master busbar by screw check without any other wire clip or insulator connection.The connection bolts on the busbar row can be insulated and sealed with end caps when required by the user and the project.When the bus goes through the switch cabinet partition, use the bus bushing to fix it.If the internal fault arc, can limit the accident to the adjacent cabinet, and can guarantee the mechanical strength of the bus.

4. The current transformer, ground switch, lightning arrester and cable can be installed in the cable room, and the seamed detachable aluminum plate can be prepared at the bottom of the cable to ensure the convenience of on-site construction.

5. The relay instrument room is used to install various components such as relays, meters, signal instructions, operation switches, etc. In addition, a small bus room can be added at the top of the instrument room according to the user's requirements, and 16 small bus bars can be laid.

6. In the handcart rooms, bus room, above the cable chamber is equipped with pressure relief device, when a circuit breaker or mistress line, cable, indoor internal arc fault occurs, along with the emergence of the arc, switch cabinet internal pressure rise, after reaching certain pressure, pressure release of metal plate at the top of the device will be automatically open, release pressure and discharge gas, to ensure the safety of operators and switchgear.
