Technical Field
[0001] The utility model relates to the technical field of cable detection, in particular to a fire-resistant test box which is convenient for feeding. Background Art
[0002] Cable testing equipment refers to the general term for equipment that detects the characteristics of cables. During the cable production process, it is necessary to test the cable's toughness, conductivity, fire resistance and other characteristics. Among them, the fire resistance test is particularly important. When the transformer is overloaded, there may be a fire hazard. At this time, if the cable connected to the transformer has good fire resistance, it will not cause a large range of cables to be burned. Therefore, we need to use cable fire resistance testing equipment to test the fire resistance of cables during cable production.
[0003] The existing Chinese patent with announcement number CN219533049U discloses a bundled cable combustion test equipment, the key points of its technical solution are: including a combustion box for combustion testing of bundled cables, and also including a visual box cover, which is detachably installed at the top opening of the combustion box; a flamethrower for combustion testing of cables, multiple flamethrowers are installed on the visual box cover; and cables to be burned, and multiple cables are arranged in the combustion box; wherein the flamethrowers correspond to the cables. In the utility model, multiple flamethrowers are installed on the visual box cover, and the flamethrowers can correspond to the cables. When each flamethrower is burning, the temperature of its flame can be set to a different temperature value. For example, the starting temperature of the flame temperature value of the flamethrower can be set to the national standard of 750°C. From then on, the flame temperature value of each flamethrower gradually increases to test the fire resistance and the limit temperature of fire resistance of each cable.
[0004] The above-mentioned prior art solution has the following defects: although the above-mentioned technical solution can test the fire resistance and the fire resistance limit temperature of each cable, in the above-mentioned technical solution, the cables are only placed through the cable placement holes, and only cables of the same size can be tested, which makes it inconvenient to test cables of different sizes, reducing its scope of application.
