Application Range |
GT7-12 Series Indoor HV AC Disconnector is suitable for indoor devices with rated frequency of 50 Hz and rated voltage of 12 kV. It can be used with all kinds of high voltage switchgear, especially for box type metal enclosed switchgear, which can make the structure of switchgear simple, compact, reasonable, safe and reliable. After opening, a safe and reliable insulation gap (obvious fracture) shall be established, and the lines and electrical equipment to be repaired shall be safely isolated from the power supply by the base frame of disconnector, so as to ensure the safety of maintenance personnel and equipment. This product is used in fixed switchgear. On the one hand, it can conduct or isolate the main circuit. When the disconnector is operated to the opening position, it can separate the repaired components (such as circuit breaker, etc.) from the live circuit (such as main bus, etc.). On the other hand, it can also be isolated and grounded at the same time. At this time, the circuit can only discharge to the ground, and will not affect the repaired components, so as to ensure the safety of maintenance personnel. |
