Abstract

The invention discloses a capacity test arrangement device for a jet fuse. The capacity test arrangement device comprises a base, stand columns, cross rods and electric arc injection prevention nets.The two stand columns are vertically arranged on the base. Each stand column is provided with a plurality of cross arms, and the three cross rods are transversely arranged on the cross arms corresponding to the stand columns. The upper cross rod and the lower cross rod are used for fixed wiring of a power supply loop in a capacity test. The middle cross rod is provided with a fixing device used for fixing a tested jet fuse. The relative positions of the three cross rods are adjustable. The electric arc injection prevention nets are fixed on the cross rods, and a tested jet fuse is arranged between the two electric arc injection prevention nets. The test arrangement device is adjusted through the three cross rods to adapt to tests of different products, and is simple in structure and low incost.

Description

technical field [0001] The invention belongs to the field of high-voltage electric appliance testing, and relates to an arrangement device for jet fuse capacity testing. Background technique [0002] According to the research on the national standard GB / T 15166.3 and IEC60282-2, the test layout requirements of jet fuses are understood, and the layout requirements for capacity tests are relatively simple. The regulations in GB / T 15166.3 and IEC60282-2 are as follows: [0003] (1) The test wiring for the test method should be as follows figure 1 As shown, it is firmly supported at a distance from the fuse base terminal (d) to prevent excessive mechanical stress on the fuse base due to the movement of the test conductor. [0004] (2) Fuses that emit ionized gas during operation should be installed so that any nearby metal devices that are at ground potential or line potential normally exist under actual operating conditions (such as the other two fuses of a three-phase fuse g...
