Description

Technical Field

[0001] The invention relates to the technical field of simulation devices, in particular to a cable high-temperature cracking simulation device. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors. In the production of finished wires and cables, high-temperature cracking simulation is required. In this case, a cable high-temperature cracking simulation device is required; The cable high temperature cracking simulator is a device used to study and test the performance changes of cables under high temperature conditions. It helps researchers and engineers understand the performance of cable materials by simulating the cracking process of cables under high temperature conditions, thereby providing a scientific basis for the design, manufacture and maintenance of cables. The traditional detection method is to adjust the temperature of the heater for detection, but the heater needs a certain amount of time to reach the specified temperature during the heating or cooling process. This process will waste detection time and reduce detection efficiency. On the other hand, there will be several or more than a dozen samples to be tested. Usually, the staff will remove the tested wires and cables and then place the next sample for testing. However, the concentration of the tested wires and cables is very high, which can easily burn the staff and pose a certain safety hazard. For this reason, we propose a cable high-temperature cracking simulation device. Summary of the invention

[0022] The working principle of a cable high-temperature cracking simulation device provided by the present invention is as follows: first, all the electric heating tubes 64 are started to heat the inside of the cracking barrel 62. During the heating process, the temperature sensor 64 detects the temperature inside the cracking barrel 62. When the temperature inside the cracking barrel 62 reaches the temperature required for the cracking test, the electric heating tube 64 is turned off. When the temperature inside the cracking barrel 62 drops, the PLC controller 15 automatically controls the electric heating tube 64 to work and reheat the inside of the cracking barrel 62. In this case, the inside of the cracking barrel 62 can be continuously maintained at the required temperature, and then the cable samples that need to be simulated are placed one by one in a uniform distribution. The four fastening plates 45 located inside the installation groove 42 are then pulled to separate. After separation, the cable sample is placed between the four fastening plates 45. The four guide rods 44 are then released. At this time, the four fastening plates 45 will fix the cable sample under the action of the four second springs 47. After all the cable samples are fixed, the electric telescopic rod 51 is started to move the extrusion column 52 to squeeze the extrusion plate 34 on the lower side. After extrusion, the fixing component 4 on the lower side and the cable sample therein enter the interior of the cracking barrel 62. At this time, the temperature inside the cracking barrel 62 can heat the cable sample. After heating, the cable sample will generate a large amount of gas. At this time, the exhaust fan 74 is started to draw the gas into the interior of the detection box 81. After entering, the gas sensors 82 evenly distributed inside the detection box 81 can detect the composition of these gases. After detection, the display 14 displays the data. After display, the user can judge the performance of the cable sample according to the displayed gas data. After the cable sample on the lower side is detected, the electric telescopic rod 51 can be retracted to make the extrusion column 52 away from the extrusion plate 34 on the lower side. At this time, under the action of the first spring 35, the fixing component 4 on the lower side and the cable sample inside it are away from the cracking barrel 62, and then the undetected cable sample is started. The infrared transmitter 9 corresponding to the tested cable sample is started, and the motor 21 is started at the same time. After the motor 21 is started, the rotating shaft 22 rotates to drive the connecting disk 24 to rotate. When the started infrared transmitter 9 corresponds to the infrared receiver 10, the fixed component 4 storing the untested cable sample will move to the position corresponding to the feed hole 65. At this time, the PLC controller 15 will restart the electric telescopic rod 51 to squeeze the untested cable sample into the interior of the cracking barrel 62 for a simulation test.
