Embodiment Construction
[0046] The following is a detailed description in conjunction with the drawings and embodiments:
[0047] 1. Automatic arc suppression system for distribution network
[0048] 1. Overall
[0049] (1) System structure
[0050] Such as figure 1 , The working platform of the present invention is an automatic arc suppression system for distribution network, including a three-phase bus 000, provided with a grounding transformer 100, an arc suppression coil 200, a thyristor 300 and a controller 400;
[0051] The primary side of the three-phase bus 000, the grounding transformer 100, and the arc suppression coil 200 are connected to the ground in sequence; the controller 400, the thyristor 300 and the secondary side of the arc suppression coil 200 are connected in sequence.
[0052] (2) System working principle:
[0053] The function of the grounding transformer 100 is to generate a neutral point for the delta connection circuit; the arc suppression coil 200 has a secondary winding to c...
