Abstract
The utility model discloses a zinc-oxide surge arrestor test rack. The rack comprises a bracket. A plurality of layers of surge arrestor fixing plates are mounted on the bracket. A plurality of fixing holes are arranged on the fixing plates. The rest rack is also provided with a grounding connection portion. Compared with test racks in the prior art, the zinc-oxide surge arrestor test rack disclosed by the utility model is capable of fixing and verifying multiple 10 kV zinc-oxide surge arrestors, solving the problem that the surge arrestors are not easy to fix, saving the working time of test personnel, and increasing the working efficiency.
Description
Technical field
The utility model relates to a kind of lightning arrester test stand.
Background technology
Zinc-Oxide Arrester is the lightning arrester with good protection performance.Utilize the good non-linear volt-ampere characteristic of zinc paste, make the electric current that when normal working voltage, flows through lightning arrester minimum, reach microampere or milliampere level; When the superpotential effect, resistance sharply descends, and the superpotential energy of releasing reaches the effect of protection.The difference of this lightning arrester and traditional lightning arrester is that it does not have discharging gap, the effect that utilizes the nonlinear characteristic of zinc paste to play earial drainage and cut-off.At present, testing crew can only carry out single built-in check when verification 10kV Zinc-Oxide Arrester, and lightning arrester is difficult fixing, and the workload of testing crew is big, badly influences job schedule, wastes time and energy.
Summary of the invention
Given this, the utility model purpose is to provide a kind of test stand that can fix many lightning arresters simultaneously.
For solving above technical matters, the technical scheme that the utility model provides is that a kind of Zinc-Oxide Arrester test stand is provided, comprise a support, at support multilayer lightning arrester fixed head is installed, described fixed head is provided with a plurality of fixed orifices, also is provided with the ground connection connecting portion on this test stand.
Preferably, described support is angle steel.
Preferably, described fixed head is band steel.
Preferably, described fixed head is ladder-like arranged.
Preferably, described ground connection connecting portion is earth stud, and this earth stud is arranged on the lower surface of lowermost layer fixed head.
Compared with prior art, the utility model can satisfy fixing and many 10kV Zinc-Oxide Arresters of verification, and has solved the difficult fixing problem of lightning arrester, the working time of having saved testing crew, has improved work efficiency.
Description of drawings
Fig. 1 is Zinc-Oxide Arrester test stand structural representation.
Embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1.The described Zinc-Oxide Arrester test stand of present embodiment comprises a support 1, and two right angle trigonometry frames about this support comprises, this triangle frame have three angle steel to be welded.At support 1 three layers of lightning arrester fixed head 2 are installed, these are flaggy ground connection shape layout fixedly.Fixed head 2 is made by band steel, and ground floor and the 3rd layer of fixed head directly are welded on the support 1, and second layer fixed head two ends are welded on the support 1 by angle steel.Arrange a plurality of for the fixing fixed orifice 3 of lightning arrester on every block of slab.The lower surface of one deck fixed head of the end 2 is provided with for the ground wire connecting portion 4 that connects earth lead, preferably uses earth stud.
Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
