Description
Technical field
The utility model relates to the measurement mechanism technical field of electrical property, relates in particular to a kind of easy to use arrester test bed.
Background technology
Lightning arrester is can discharge thunder and lightning or hold concurrently to discharge power system operation superpotential energy, and protection electrical equipment is avoided instantaneous overvoltage harm, can block afterflow again, the unlikely electrical installation that causes system earth short circuit.Lightning arrester is connected between live wire and ground conventionally, in parallel with protected equipment.When overvoltage value reaches the operation voltage of regulation, lightning arrester moves immediately, flows through electric charge, and over-voltage amplitude is protected apparatus insulated; After magnitude of voltage is normal, lightning arrester restores to the original state rapidly again, to guarantee system normal power supply.Modern high-voltage arrester, the superpotential not only causing because of thunder and lightning for limiting electric system, also for limiting the superpotential producing because of system operation.Lightning arrester is that the protected equipment of transformer station exempts from the equipment that lightning surge attacks.When importing the lightning surge of transformer station over protection of arrester level into along circuit; first lightning arrester discharges; and by the introducing the earth of lightning current process conductor safety, utilize earthing device to make lightning voltage amplitude limitation below horizontal at protected equipment lightning impulse, electrical equipment is protected.
Along with the development of power industry, also there has been new requirement in country to electric power safety work.Zinc-Oxide Arrester is the visual plant that guarantees equipment safety operation, and Zinc-Oxide Arrester is tested, and is that can whether these Zinc-Oxide Arresters of check meet service condition, the Main Means that normally move.At present, in power industry Test Speciality, lack the effective utility appliance for lightning arrester verification, test is subject to environmental limit in work, the accuracy of impact test.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of arrester test bed, uses that described testing table is auxiliary carries out test of lightning arrester, has easy to usely, and test figure is more stable, feature more accurately.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of arrester test bed, it is characterized in that comprising half testing table of two same structures, described half testing table comprises base plate, the first back up pad and the second back up pad, what described the first back up pad was vertical with the second back up pad is fixed on described base plate, described the first back up pad is parallel with the second back up pad, the first back up pad and the second back up pad are provided with the groove of opening upwards, and described base plate, the first back up pad and the second back up pad are insulcrete.
Preferably, described half testing table also comprises the first side plate and the second side plate, described the first side plate with the second side plate with base plate, the first back up pad with the second back up pad is vertical is fixedly connected with, and described the first back up pad and the second back up pad are between described the first side plate and the second side plate, and described the first side plate and the second side plate are insulcrete.
Preferably, the distance between described the first back up pad and the second back up pad is less than the length of lightning arrester, and described groove is semi-circular recesses.
Preferably, described the first side plate and the second side plate are provided with handle.
The beneficial effect that adopts technique scheme to produce is: described testing table comprises two half testing tables that structure is identical, when doing test of lightning arrester, lightning arrester is placed in the back up pad of one and half testing tables, buckle another half testing table, lightning arrester terminal one end ground connection, one end joint test instrument.Described testing table all uses insulcrete material to make, and when lightning arrester is carried out to testing experiment, plays the effect of support, protection lightning arrester, the on-the-spot safety of using, and can prevent that testing crew from touching lightning arrester in process of the test, and make test figure more stable, improved the accuracy of test; Two back up pads of half testing table are provided with the groove suitable with lightning arrester, and lightning arrester can be stuck in groove, prevent that it from rocking in the process of test, and side plate is provided with handle, mobile easy to use.In addition, described testing table simple in structure, low cost of manufacture, has good popularization and prospect of the application.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of half testing table;
Wherein: 1, base plate 2, the first back up pad 3, the second back up pad 4, groove 5, the first side plate 6, the second side plate.
Embodiment
A kind of arrester test bed, comprise half testing table of two same structures, as shown in Figure 1.Described half testing table comprises base plate 1, the first back up pad 2 and the second back up pad 3, what described the first back up pad 2 was vertical with the second back up pad 3 is fixed on described base plate 1, described the first back up pad 2 is parallel with the second back up pad 3, the first back up pad 2 and the second back up pad 3 are provided with the groove 4 of opening upwards, and described base plate 1, the first back up pad 2 and the second back up pad 3 are insulcrete.
In order to strengthen the intensity of testing table, increase the service life, described half testing table also comprises the first side plate 5 and the second side plate 6.Described the first side plate 5 and the second side plate 6 and base plate 1, the first back up pad 2 are with second back up pad 3 is vertical is fixedly connected with, and described the first back up pad 2 and the second back up pad 3 are between described the first side plate 5 and the second side plate 6, and described the first side plate 5 and the second side plate 6 are insulcrete.In order effectively lightning arrester to be wrapped, the distance between described the first back up pad 2 and the second back up pad 3 is less than the length of lightning arrester, and described groove 4 is semi-circular recesses.Further, for mobile easy to use, on described the first side plate 5 and the second side plate 6, handle is set.
