Description
12kv Metal Enclosed High Voltage Switchgear
KYN28-12 armored installation metal-enclosed switchgear is suitable for 3.6-12kv three-phase AC grid, used for receiving and distributing electric energy and controlling, monitoring and protecting circuits. It can be used in the bus section system of single bus, single bus or double bus system. The switchgear complies with IEC62271 "AC Metal-enclosed Switchgear and Control Equipment with Rated Voltage Above 1KV and 52KV", IEC694 "General Provisions for High-Voltage Switches and Control Equipment", China GB3906 "3.6~40.5KV AC Metal-enclosed Switchgear and Control Equipment", DL/T404 "Order Conditions for Indoor AC High Voltage Switchgear". It also has perfect and reliable shell operation functions.
![]() | Feature: 1. Completely metal wrapped and completely enclosed to prevent dust and small animals from entering. 2. Each compartment in the switchgear is separate and independent of each other. 3. Quickly close the grounding switch for grounding and manual short-circuit. 4. All operations on the equipment can and should be performed with the door completely closed, including opening/closing of the circuit breaker, in/out of the circuit breaker trolley, and opening/closing of the grounding switch. 5. The trolley of the vacuum circuit breaker is maintenance-free, the matching operating mechanism requires the least maintenance, and has good interchangeability, and the circuit breaker can be easily replaced. 6. Easily check the location of the circuit breaker, its opening/closing and charging status through the front door observation window. 7. The reliable FIVE-PREVENTION interlock can effectively prevent misoperation and entry into the energized carriage. |
