A explosion -proof block for condenser

The utility model relates to an explosion -proof block for condenser belongs to capacitor bank spare field, including the block, the oval groove has been seted up on the block, the wiring hole of running through the block is seted up to the oval inslot, an oval groove place side surface is provided with a plurality of convex parts of evenly distributed on the block, the clearance has between the convex part. This technical scheme sets up the convex part at explosion -proof block's block with the surface that the condenser upper cover contacted, and the effect of this kind of protruding structure has two, and there is the clearance in the contact surface when firstly making explosion -proof block with the contact of condenser upper cover, can supply electrolyte to pass through, the homogeneity of electrolyte environment in the assurance condenser, secondly, in the current explosion -proof block production process, because production technological problem can produce the burr, during the in -service use, explosion -proof block is not good with condenser upper cover laminating effect, therefore this kind of protruding structure can improve the fastness of the contact between explosion -proof block and the condenser upper cover, and beneficial effect is showing.
