Abstract
The utility model discloses a special tool for zinc oxide lightning arrester tests, and solves the problems that the existing test device requires overlong time and the working efficiency is low. The special tool is characterized by comprising an upper disc, a lower disc and a tray, wherein connecting pieces and runners are arranged between the upper disc and the lower disc, and the bottom surfaces of the runners are positioned on the tray; a rotating component connecting the upper disc and the lower disc is arranged at the central position of the tray; and a plurality of clamp springs which can be inserted by lightning arresters are arranged on the lower disc, and the upper disc is provided with holes at positions corresponding to the clamp springs. The special tool provided by the utility model shortens the testing time, improves the grounding safety factor, and reduces the number of testing personnel.
Description
Technical field
The utility model relates to a kind of test instrument, relates to or rather a kind of test instrument for lightning arrester.
Background technology
In annual spring, along with carrying out of Thunder Protection, a large amount of lightning arresters need to be done preventive trial.In the past test of lightning arrester test method falls behind, and random strong, the time spent is long, and work efficiency is lower, and safety coefficient is little, and is few personnel, be pressed for time, make easily the tired operation of testing crew in task is heavy, workload the is large situation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art a kind of Zinc-Oxide Arrester test specific purpose tool is provided, improve the test efficiency of Zinc-Oxide Arrester, can be fit to the test of the Zinc-Oxide Arrester of various shapes, shorten test period, reduce labor intensity and the safety coefficient of warranty test.
Of the present utility model being characterised in that comprises and disk, lower disc, pallet web member and runner is set between upper disk, the lower disc that described runner bottom surface is on pallet; The rotary part of disk in the connection, lower disc is set in the pallet centre position; At lower disc some jump rings that can insert lightning arrester are set, on upper disk, leave the hole with the corresponding position of jump ring.
Described runner is universal wheel.
Described rotary part is bearing.
Described jump ring quantity is 15-30, and described runner is 2-8.
As shown from the above technical solution, when the utility model uses, only need a plurality of respectively lightning arresters are placed on the jump ring of upper disk, do not need lightning arrester is intertwined and connected with wire singly, just can make a service test to each lightning arrester that is placed on the lower disc by rotating simply upper disk.The test method standard of lightning arrester is 1 milliampere of magnitude of voltage under the electric current, then is that the current value under 0.75 residual voltage reaches the setting that producer dispatches from the factory.With this instrument Zinc-Oxide Arrester is tested, its ground connection is very firm, and thread-changing is simple and convenient, has reduced the test figure that causes because ground connection is insecure in the past and has exceeded standard and carry out the time of repetition test.
Therefore, the utility model has shortened test period, can be reduced to 2.10 minutes by in the past each 3.50 minutes; Improved the grounding safety coefficient, by in the past 98% bring up to 100%; Reduce testing crew, reduced to 2 people by in the past 4 people; By the thread-changing operation, complicated operating process is oversimplified, reach the labour intensity and the security that reduce testing crew in the time that shortens test of lightning arrester and obtained obvious effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vertical view of the present utility model.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, 2, the utility model comprises disk 1, lower disc 6, pallet 7 etc.
Web member 3 and runner 4 are set between upper disk 1, the lower disc 6.Described web member 3 is bolt, nut structure, in order to be connected and fixed upper disk 1, lower disc 6 is in aggregates.Described runner 4 is universal wheel, can assist disk 1, lower disc 6 to rotate at pallet 7; The upper end of runner 4 is fixed on the upper disk 1 with nut, and the bottom surface of wheel is fluffy on pallet 7; Lower disc 6 has larger hole, is convenient to runner 4 and rotates.
The rotary part of disk 1 in the connection, lower disc 6 is set in the centre position of pallet 7, disk 1, lower disc 6 are rotated at pallet 7.Described rotary part 5 is bearing.
At lower disc 6 some jump rings 2 that can insert lightning arrester are set, about described jump ring 2 aperture 10mm, similar setscrew.On upper disk 1, leave the hole with jump ring 2 corresponding positions.
As shown in Figure 2, described jump ring quantity is 20, and described runner is 4.
