Specification
22kV switchgear is a new generation medium-voltage switchgear develped by our company, is applicable to three-phase AC 50/60Hz
system with a rated voltage of 24kV. It functions as the indoor metal-enclosed switchgear mainly for the receiving and
distribution of electric energy.
Features:
1. Metal-clad and fully enclosed structure, can prevent dirt and small animals from entrance.
2. Each small compartment in the switchgear is separated and independent from each other.
3. Fast closing earthing switch is used for earthing and provides short-circuit current closing capacity.
4. All operations can be conducted when the door panel is closed, including breaker switching on and off, breaker trolley's
drawing in or out, as well as earthing switch's switching on and off.
5. Reliable latch device is used to effectively prevent misoperation.
6. VCB trolley is maintenance free and the equipped operating mechanism requires only a little maintenance. Good
interchangeability of trolleys, very easy to replace circuit breakers.
7. Through the front and rear observation windows in the door panel, breaker's switching status, trolley position, mechanism
energy stored status, earthing switch switching position and cable end connection status can be clearly viewed.
8. Secondary wire is laid in ample wire casing, neat and convenient for inspection.
9. Reliable FIVE-PREVENTION interlock can effectively prevent from mal-operation and entrance into energized compartments.
Structure:
1. KYN28A-20 switchgear is composed of cubicle and removable parts (so called trolley). The cubicle is separated into several functional compartments by metal sheet, including busbar compartment, circuit breaker compartment, cable compartment and low voltage compartment.
2. Switchgear removable parts can be equipped with VCB trolley, voltage transformer trolley, lightning arrester trolley and fuse trolley.
3. Pressure relief devices are installed above trolley compartment, busbar compartment and cable compartment. Special sealing ring on the door seals the panel door. In case of faults inside the compartments resulting in arc, the pressure is going up inside the switchgear and the pressure relief equipped on the top will open automatically, to release pressure and high temperature gas. In this way, it can ensure the safety of operating staff and the switchgear.
4. The secondary connection of the switchgear and trolleys are conducted via secondary plug coordination. The secondary plug is connected to trolleys through a nylon bellow. The plug is located on the upper right side of switchgear’s trolley compartment. Only when the trolley is on Test position, the secondary plug can be plug in or out. When the trolley is on Operating position, the plug is locked.
5. The switchgear is installed electrical indication device in primary circuit. The device includes high voltage sensors and an indicator, and can indicate high voltage circuit electrical status. It can also cooperate with electromagnetic lock to conduct compulsory latching on operating handle, cubicle door and adjacent cubicles. Thus, it can prevent from withdrawing isolation trolley with loads, prevent earthing switch from energized closing, and prevent from entrance of energized compartment. In this way, it can increase prevention performance of the equipped products.
6. In order to prevent condensation in high humidity or dramatically changed temperature environment, electrical heater is
installed separately in circuit breaker compartment and cable compartment, to avoid dielectric accidents in the above conditions.
7. Cable compartment installs additionally earthing copper busbar which goes through adjacent cubicles and with good connection to cubicles. The copper busbar is used for direct earthing components. Since the whole cubicle is joint by aluminum zinc coated steel plates, the cubicle is in good earthing status, thus ensuring safety of operating staff.
