Problems solved by technology
[0003] Existing fuse tests are carried out manually. For example, when testing the durability of a fuse, the operator needs to wait by the instrument and manually record the duration of the fuse blowing on paper. Such testing not only wastes manpower, but also if The operator misses the moment when the fuse is blown, and it is inconvenient to accurately record the characteristic value; moreover, the tester using manual detection is a single independent test, and one tester needs a control terminal to control, which wastes a lot of material resources

The invention discloses a fuse test system, which comprises a plurality of test devices, a data bidirectional communication unit and a monitoring control terminal, wherein each test device comprises a test power supply, a detection system and a control unit; the test power supplies supply running power to the detection systems; tested fuses are put on the detection systems; the control units control the detection systems to detect the property characteristics of the tested fuses and record a switch on and switch off time intervals of the tested fuses; the data bidirectional communication unit is electrically connected between the monitoring control terminal and the control units; and the monitoring control terminal receives property detection signals of the tested fuses transmitted from the control units and controls the control units. According to the invention, the monitoring control terminal controls the test devices, the detection systems detect the property characteristics of the tested fuses and send the switch on and switch off time intervals of the tested fuses to the monitoring control terminal through the control units, and therefore, a function of knowing a property detection result of each tested fuse without manual monitoring can be realized.
Description
technical field [0001] The invention relates to the field of fuse testing, in particular to a fuse testing system. Background technique [0002] Fuses have a positive temperature coefficient effect and can be widely used in protective circuits for computer peripherals, rechargeable batteries, power supplies, automotive electronics, and telecommunication equipment. Etc. Fuses are nonlinear components, and their operating protection characteristics are usually given in the form of empirical curves. It is necessary to test the electrical properties of the applied products such as life, fusing, durability, surge, impact, voltage drop or temperature rise. [0003] Existing fuse testing is carried out manually. For example, when testing the durability of a fuse, the operator needs to wait by the instrument and manually record the duration of the fuse blowing on paper. Such testing not only wastes manpower, but also if The operator misses the moment when the fuse is blown, and i...
