5: It has high mechanical strength and its neatness and beauty is ensured.

 

6: The switchboard door is sprayed with plastic, also has strong capacity of impact resistance and corrosion protection.

 

7: The primary switch may be provided with VD4 vacuum circuit breaker and C3 series of fixed type load switch from ABB, various domestic vacuum circuit breakers (such as VS1, VH1, VK, ZN28) may also be provided in lieu of the same foreign products.

 

8: Front door is installed with a observation window to check the operating state of the components inside the room

 

 

Five steps for power outage operation of KYN28 armored movable AC metal enclosed switchgear main power cabinet

 

1) Observe all cabinet related signals and confirm that all outgoing cabinet circuit breakers are in the open position.

2) The switching switch causes the circuit breaker to open and power off, while the red closing indicator light on the instrument door is off and the green opening indicator light is on. Upon checking other relevant signals, everything is normal and the power outage is successful. (When operating the on/off switch, rotate the operating handle counterclockwise to the indicated open position on the panel. After releasing the handle, the operating handle should automatically reset to the pre open position.)

3) Insert the circuit breaker handcart handle into the handle socket and press it down with force. Rotate the handle counterclockwise for about 20 turns, and remove the handle when it is clearly blocked and accompanied by a "click" sound. At this time, the handcart is in the test position, and the aviation plug is unlocked. Open the handcart compartment door and manually release the aviation plug. (Handheld vehicle circuit disconnected)

4) Observe the live display and confirm that it is not live before continuing operation. (The lower door of the incoming cabinet has a Electromagnetic lock for forced locking, which can only be unlocked when the incoming terminal is not electrified, but can also be unlocked with a key for emergency unlocking when the incoming terminal is electrified. Opening the incoming circuit breaker does not mean that the incoming cabinet is not electrified. If the external power supply is not stopped, the cable chamber is electrified at this time, and forced entry is life-threatening.)

5) Open the lower door, conduct electrical testing (necessary), discharge (necessary), and hang the grounding wire (necessary). Maintenance personnel can enter for maintenance and repair.

4、 The operation procedure of the backup power cabinet is the same as that of the main power cabinet.

As the relevant content has already been introduced earlier, which includes the seven steps of power transmission operation and the five steps of power outage operation, we will not elaborate further.

 

5、 Three steps for operating the measuring cabinet

1) The measuring handcart is directly connected to the moving and stationary contacts, and does not have the ability to break or extinguish arcs. It must not be shaken in or out with load.

2) The metering handcart and the circuit breaker of the incoming switchgear have electrical and mechanical interlocks. Only after the main power supply (backup power supply) circuit breaker is opened can the metering handcart be operated to swing in or out. Forced operation is not allowed to avoid damaging the interlocking device. When the measuring handcart is forcibly shaken out with load, the main power (backup power) circuit breaker will automatically open to avoid personal injury or death.

3) The method of shaking in and out the measuring handcart is the same as that of the circuit breaker handcart.
