Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further.
Refer to Fig. 1 to Fig. 5, this utility model provides a kind of technical scheme: a kind of drop type Zinc-Oxide Arrester with standby spark gap, fixing plate 11 and base plate 12 including insulation column 1 and point described insulation column 1 upper and lower end of row, described fixing plate 11 includes an insulation division 111 and cold two fixed parts 112, described fixed part 112 is fixed with downward opening fixing groove 4 and conductive plate 5, described conductive plate 5 is arranged on the lower section of fixing groove 4, is provided with stage clip 6 between fixing groove 4 and conductive plate 5；Described base plate 12 has two connecting portions 121, and described connecting portion 121 is provided with hook；Also including conventional spark gap 2 and standby spark gap 3, the lower end of described conventional spark gap 2 and standby spark gap 3 hangs on two described hooks respectively through a releasing mechanism, and upper end is connected with two described conductive plates 5 respectively through a metal contact；Also include across the switch boards 8 being arranged on above two fixing grooves 4 and the connecting plate 9 described switch boards 8 being fixed on the conductive plate 5 being connected with conventional spark gap 2；Being provided with high tension terminal 7 on the fixed part 112 electrically connected with conventional spark gap 2, when described conventional spark gap 2 departs from conductive plate 5, described switch boards 8 contacts with two fixing grooves 4 with the movement of conductive plate 5.Preferred described connecting plate 9 and conductive plate 5 integrated setting, and have two pieces, set up fixing groove 4 two ends separately, and coordinate with fixing groove 4 side slip, it is more firm so to arrange.When conventional spark gap 2 departs from conductive plate 5, stage clip 6 promotes conductive plate 5 to move down, thus driving switch boards 8 also to move down, and then by switch boards 8 by high tension terminal 7 and standby spark gap 3 electric connection.By above-mentioned setting so that the drop type Zinc-Oxide Arrester with standby spark gap of the present utility model can avoid the damage that circuit and equipment are caused by second time overvoltage.
