Embodiment 1
[0046] Such as image 3As shown, it is a three-unit combined explosion-proof arrester. This embodiment is suitable for each independent unit discharge voltage is 3.3KV, and its combined overall voltage is 10KV explosion-proof and lightning protection device. It is composed of three groups of units combined in series, gap pressure equalization and explosion-proof main part and fixed sealing shell part; the main part is composed of three units, and the structure of the upper, middle and lower units is roughly the same.
[0047] The main part of each unit is as image 3 As shown: the effective discharge large-plane porous ventilated discharge gap valve group (2) clamps the hollow insulating gasket (3) to form an effective discharge large-plane porous ventilated discharge gap valve group, which is inlaid and bonded in series with the surrounding waist. The center of the insulation arc-shielding positioning garden disc (5) has a vent hole and sticks a hollow ventilating metal zin...
