General Description:

KYN28A-12/15/24kV

Air-insulated Metal-clad Withdrable Switchgear

Fitted with VD4/VS1 (ZN63A) Withdrawable Vacuum Circuit Breaker

Provided Customized manufacture

High reliable, compact, environmental protection...

KYN28A-12/15/24 air-insulated metal-clad withdrawable switchgear (hereinafter as "switchgear") is a necessary indoor power distribution equipment 3-phase AC 50/60Hz. It is mainly used to receive and distribute 3-24kV network electrical and control protection and monitoring to line circuit. Relay chamber panel can install in various types of microprocessor based relay protection device , and can realize the intelligent control system, with remote control, telemetry, remote communication and remote transfer function, through the CAN communication interface with fieldbus control network to prevent the mal-operation of circuit breaker, to prevent pushing and pulling handcart with load, to prevent grounding switch closed with charged, to prevent the grounding switch in the grounding position transmission and to prevent into live space, which is referred to as the "five-anti" function. The cabinet is equipped with VS1 , Vacuum circuit breaker, also can be equipped with imported VD4 vacuum circuit breaker and VC series vacuum contactor.

3. Circuit breaker chamber

4. Bus chamber

5. Cable chamber

6. Relay instruments chamber

7. Bus bar

8. Fix contact box

9. Circuit breaker

10. Earth switch

11. Current transformer

12. Capacitive voltage divider

13. Lightning arrester

The switchgear is composed of a fixed body and a with drawable part (the handcart) , switchgear enclosure and function modules are using aluminum-clad galvanizedsteel sheet to bolt together , The protection level of the switchgear enclosure is IP3X, while the protection level is IP2X between the partition boards and circuit breaker door .

KYN28A-12/15/24 type switchgear could match VS1 type vacuum circuit breaker handcart and VD4 vacuum circuit breaker handcart and ABB manufactured VC series vacuum contactor, switchgear can be installed to back-to-back arrangement. The switchgear installation and commissioning can be operated in the front, so the switchgear can be mounted against the wall, the biggest advantage of againsting the wall can save area, and can also oft' wall installation, namely double maintenance type, the two of internal structure layout is not uniform, it has the advantages of convenient maintenance

Enclosure and partition

The enclosure and partition of the switchgear is made of top quality imported aluminum-clad galvanized steel sheet through multiple edge-folding processing with CNC machine tool. The assembled switchgear could keep uniform in dimension, and it has high corrosion resistance and oxidation resistance and higher mechanical strength than equal steel sheet. The switchgear is divided to handcart chamber ( circuit breaker chamber ), bus chamber , cable chamber and relay instrument chamber ( LV chamber) each unit enclosure are independently earthing.

Cabinet overview

The enclosure and partition of the switchgear is made of top quality imported aluminum-clad galvanized steel sheet or steel sheet through multiple edge-folding processing with CNC machine tool. The assembled switchgear could keep uniform in dimension. Aluminum-clad galvanized steel sheet has a strong corrosion resistance and oxidation resistance, and higher mechanical strength than qual steel sheet. The switchgear is divided to handcart chamber ( circuit breaker chamber ), bus chamber , cable chamber and relay instrument chamber ( LV chamber ) each unit enclosure are independently earthing .The door of switchgear are using electrostatic spraying to make the surface with the advantage of anti impact, corrosion resistance, beautiful appearance (color can be set by the user) etc...
