High -voltage switching cabinet refers to the role of power, control or protection in power system power generation, transmission, power distribution, electrical conversion and consumption.With the ground switch, high -voltage load switch, high -voltage automatic overlapping and segmentation, high -voltage operating mechanism, high -voltage explosion -proof power distribution device, and high -voltage switch cabinet.
The role of high -voltage switch cabinet
The role of the switch cabinet is to break the high -voltage circuit, which is the main equipment of the high -voltage switch cabinet.The bus and cables are connected. Generally, the bus is connected to the system side, which is equivalent to the source of high voltage, and then connects to the cable through the switch.The load of the cable connecting the switch.It can be a transformer or a motor or other device.

2. The high -voltage switch cabinet meets the requirements of the national standard GB3906 "3 ～ 35KV AC metal closed switching equipment" and the international standard IEC298, and has the "five -defense" lock function.3. The main switch of this high-voltage switch cabinet adopts the ZN28A-10 series real vacuum circuit breaker with the CD10 series and the CD17 series electromagnetic and CT8 series and the CT17/CT19 series spring operation mechanism.The overall circuit breaker, the isolation switch is an GN30-10 rotary isolation switch, the GN22-10 large current isolation, and the GN30-10 rotating large current isolation isolated the product.
High -pressure switch cabinet standard
The KYN indoor communication metal armor-migration switch equipment (referred to as a hand car cabinet) is based on the "3-35kV AC metal closed switch equipment" according to the standard design and manufacturingMeeting the high -voltage switch cabinet proposed by the Ministry of Hydropower should have the requirements of the "five defense" function.Middle and high -end mainstream cabinet types are mainly commonly used.A, KYN-10 indoor AC metal armor-off switching equipment (referred to as hand cart) hand car cabinet is suitable for communication 50Hz rated voltage 3-10kV center points unmotned single-parent line and single parent line segment system householdThe inner set power distribution device is provided for various types of power plants, substations and industrial and mining enterprises as acceptance and distribution of network electrical energy to control and monitor the circuit.
High -pressure switch cabinet structure
The switching cabinet is divided into a handle room, a bus room, a cable room, and a relay instrument room, and each unit is well grounded.The bus room of the bus room is arranged on the upper part of the back of the switch cabinet for installation and arrangement of three-phase high-voltage AC bus and the use of the tentacles of static through the parent line of the branch.All the parent lines are placed with insulating sleeves.When the bus is crossing the switch cabinet, it is fixed with the bus holder.If an internal fault arc occurs, the accident can spread to the neighboring cabinet and ensure the mechanical strength of the bus.The B-Hand Car (circuit breaker) room is equipped with a specific guide rail in the circuit breaker room for the trolley of the handwritten hand car in inside.Hand cart can move between working and test positions.Static partitions (living doors) are installed on the back wall of the hand room.From the test location to the working location, the partition is automatically opened, and the movement of the hand car in the opposite direction is completely compounded, thereby ensuring that the operator does not touch the charger.
