Product Introduction
KGQ1 series blasting cutting type fast isolator is the core component of DDXK1 series high-current current limiting circuit breaker/DGXK1 series large-capacity high-speed switch, which flows over the load current as the main electrical circuit during normal operation, and opens the multi-series break of its leading circuit at high speed when a short circuit fault occurs, forming an insulation break with high insulation strength. The seal is explosion-proof, and the user replaces it after the action, and the manufacturer provides users with spare parts for a long time at a favorable price.
Feature
Main parameters
Rated voltage: 7.2~40.5kV
Rated current: 630~6300A
Breaking time: 150~300μs
After the main circuit breaker cuts off the fault, KGQ1 can complete mechanical isolation within 1-3 milliseconds, form a high insulation strength fracture, prevent reverse power transmission, and ensure maintenance safety.
Yes, its compact design (width ≤ 800mm) can be directly integrated into standard high-voltage switchgear such as KYN28 and XGN, supporting independent or cabinet installation.
KGQ1 adopts a blasting cutting structure, and the body needs to be replaced after the action, but the manufacturer provides long-term discounted spare parts, and the maintenance cost is controllable.
