Abstract
The invention provides a quick arc-extinguishing device for extinguishing an arc of a high-voltage switch cabinet. The quick arc-extinguishing device structurally comprises a fixed contact 2, an arc-extinguishing chamber ceramic shell 3, a moving contact 4, a grounding contact 5, a watchband contact finger 6 and a miniature gas generator 7, wherein the fixed contact 2 is located at the upper part of the arc-extinguishing chamber ceramic shell 3; the grounding contact 5 is located at the lower part of the arc-extinguishing chamber ceramic shell 3 and is grounded; the watchband contact finger 6 is arranged in a groove of the moving contact 4; the moving contact 4 is arranged in a hole in the grounding contact 5; and the miniature gas generator 7 is arranged at the bottom part of the grounding touch 5. The quick arc-extinguishing device has the advantage that a main loop of the switch cabinet is grounded; and a switch cabinet protecting device sends out a circuit breaker breaking command of the cabinet, so that the switch cabinet is powered off. The time from the moment when an arc probe sends out a signal to the moment when an electronic detection device receives the signal is about 2ms; the time from the moment when the electronic detection device sends out the signal to the moment when the quick arc-extinguishing device extinguishes an arc light is about 2ms; and the condition that the arc duration is about 4ms is ensured, so that the arc energy is reduced and the safety of switch cabinet equipment is ensured.
