It should be noted that, when element is considered to " setting " on another element, it can be set directly on another element or may there is centering elements simultaneously.Term used herein " top ", " bottom " and similar statement are just for illustrative purposes.
Unless otherwise defined, all technology used herein are identical with the implication that those skilled in the art of the present utility model understand usually with scientific terminology.The term used in instructions, just in order to describe concrete enforcement object, is not intended to be restriction the utility model.
Preferably, test of lightning arrester base is herein applicable to 10kV ~ 35kV zinc oxide arrester test base.
Referring to Fig. 1 ~ 2, is the test of lightning arrester base of an embodiment, comprises base body 10 and support 20.
Wherein, base body 10 is provided with mounting hole 12 along its longitudinal direction, and mounting hole 12 runs through base body 10.
Mounting hole 12 is for zinc oxide surge arresters.
In the present embodiment, the quantity of mounting hole 12 is one.Be appreciated that in other embodiments, the quantity of mounting hole 12 can also be multiple, installs multiple lightning arrester to facilitate according to testing requirements.
Base body 10 is provided with pilot hole 14 along its horizontal direction, and one end of pilot hole 14 is connected with mounting hole 12, and the other end runs through base body 10.
Fixture (not shown) is provided with, for fixing lightning arrester in pilot hole 14.
Preferably, fixture comprises the steel ball, elastic body and the screw that set gradually, and steel ball is arranged on the one end near mounting hole 12 in pilot hole 14.
Concrete, elastic body is spring or shell fragment.The diameter of steel ball is about 4mm.
Lightning arrester is appreciated that the quantity of pilot hole 14 can be more than one, as long as can be fixed by the fixture arranged in it.
It should be noted that, above-mentioned base body 10 is metal, can be placed on separately on arbitrary insulation bench or insulation structure body and use.
In addition, because base body 10 is metal, more durable.
