れていた。2. Description of the Related Art A power surge arrester is a stack of surge arrester elements made of zinc oxide and housed in a porcelain tube or a tank. In the process of manufacturing this lightning arrester, there is not much problem if it is carried out in the same factory site from the production of the element to the storage and assembly of the insulator and the tank. However, when the contents such as elements are manufactured at another remote factory, only the contents have to be transported, and a dedicated transportation jig is required. FIG. 3 is a cross-sectional view showing the structure of a conventional transportation jig for a lightning arrester element. The content 30 of the lightning arrester is composed of a plurality of stacked elements 1, and the high-voltage electrode 3 and the low-voltage electrode 4 sandwiching the element 1 from above and below.
And a pedestal 14 for fixing the low voltage electrode 4. The high voltage electrode 3 is provided with a metal shield 5 for relaxing an electric field around the high voltage electrode 3, and the low voltage electrode 4 is provided with a low voltage terminal 6 for grounding. As a jig for transporting the contents 30, a cylindrical metal container 31 whose upper end and lower end are closed by the upper lid 19 and the pedestal 70, respectively, has been used. This metal container 3
Feet 18 that store contents 30 in 1 and are fixed to pedestal 70
And the pedestal 14 was fixed by the bolts 21. The cushion material 2 is provided between the high voltage electrode 3 and the upper lid 19.
0 was inserted, and the contents 30 were held down so as not to tilt.

A desiccant (not shown) is arranged in the metal container 31 so that the contents 30 do not absorb moisture. After transportation, the metal container 31 is removed and the leakage current of the element is measured to check the contents 30. After that, the contents 30 are stored in a porcelain insulator or tank for the product, and the lightning arrester is completed.

る。However, the conventional device as described above has a problem that the leakage current of the element cannot be measured in the state of being transported. That is, in the conventional apparatus shown in FIG. 3, the metal container 31 was once removed to measure the leakage current of the transported element 1, and the contents 30 were left bare. In the leakage current measurement, a current is passed from the high voltage electrode 3 to the low voltage terminal 6 via the element 1 and it is checked whether the current value is within the control value. After completing this check, the contents 30 are stored again in the metal container 31, and the next step, namely,
It was preserved up to the process of storing the contents 30 in a lightning arrester insulator tube or tank. If these steps are continuously carried out immediately, there is no problem. However, if it takes a long time to enter the step of storing in the porcelain tube or the tank, if the content 30 is left naked, the element may be soiled or may absorb moisture. For this reason, the work of re-storing the contents 30 in the metal container 31 for storage has been required. If it becomes possible to measure the leakage current while it is being transported,
Since the contents can be stored as they are after the measurement, it is possible to save unnecessary work such as re-storing work in a metal container.
