Kyn28 /61 12kv 40.5kv High Voltage Electric Equipment /Highvoltage Switchgear with Circuit Breaker Factory Price,electrical switch
KYN28-12 (GZS1) indoor metal-fitted mid-shift open type switchgear (hereinafter referred to as the switch cabinet) is a three-phase ac 50Hz indoor power distribution unit, which is used to receive and distribute 3-12kv network power and to control, protect and monitor the circuit.The product CAN be installed on the panel of the relay chamber of various types of microcomputer type integrated relay protection devices, and CAN achieve intelligent control of the system, with remote control, telemetry, remote communication and remote control functions, CAN bus with communication interface to control the field network.It also has the function of preventing the wrong operation of the circuit breaker, preventing the trolley from pushing and pulling with load, preventing the electrifying closing grounding switch, preventing the grounding switch from sending electricity at the grounding position and preventing the electrifying interval from entering by mistake, which is referred to as "five defense".
Switchgear Structure
Structural features:
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.
