Description
Technical Field

Background
According to the research on the national standard GB/T15166.3 and IEC60282-2, the test arrangement requirement of the expulsion fuse is known, and the arrangement requirement on the capacity test is relatively simple. Wherein GB/T15166.3 and IEC60282-2 stipulate the following:
(1) The test connections for the test mode are firmly supported at a distance (d) from the fuse base terminals as shown in fig. 1 below to prevent excessive mechanical stress on the fuse base due to movement of the test conductors.
(2) Fuses that inject ionized gases during operation should be installed such that any nearby metal devices (e.g., the other two fuses of a three-phase fuse bank) that are normally present at ground or line potential under actual operating conditions are simulated during short circuit testing.
The more detailed requirements for the expulsion fuse capacity test arrangement are made in IEC60282-2 STL guide:
(1) The arrangement of fuses for outdoor use is required to be insufficient to provide sufficient rigidity and representative conditions in different laboratories and should be based on the test arrangement of IEC 60282-2.
(2) As shown in fig. 1, the connection conductors should be folded at a suitable angle to the sample site at a distance of not more than 100mm beyond the support point, the distance being at least 500mm. Similar dimensions apply to the safety conditions of a canted fuse, the angle of inclination being specified by the manufacturer.
(3) The distance d should be equal to the open distance of the fuse. The power bus bars must be supported for a distance not exceeding d +100 mm. In addition, the bus bar extends at least 500mm from the test circuit as shown and then is folded toward the fuse.
(4) The distance d should be equal to the open distance of the fuse. The power bus bars must be supported for a distance not exceeding d +100 mm. In addition, the bus bar extends at least 500mm from the test circuit as shown and then is folded toward the fuse.
(5) The fuse base should be installed on a structure with enough rigidity, the support should be able to bear the thrust when the fuse is cut off without excessive deformation, when a test loop is connected, the maximum wire diameter should be determined according to the rated current of the fuse, and a semi-flexible coaxial cable (non-rigid bus) is used for connection, and the size of the cable is the same as the recommended value of the temperature rise test in the table 14.
(6) For fuses mounted to ground for fuse venting, manufacturers should provide installation distances and fuse venting restrictions, drainage areas, and bus bar connections related to insulation. The arrangement of the test pieces is determined by the laboratory in terms of the minimum insulation distance and the maximum venting restriction area. The layout size, installation distance, venting and limits of the test are reported.
With the development of fuse technology, the arrangement requirement of the fuse-jet capacity test is more strict, different test arrangement requirements are provided according to actual requirements, the existing arrangement device of each high-voltage electrical appliance detection room at present cannot completely meet the test requirements, and particularly, no test device can be suitable for different standards of the fuse-jet and products with different voltage grades in various countries.
