Description

TECHNICAL FIELD

[0001] The utility model relates to the production and manufacturing technical field of motor train unit, especially relates to a motor train unit whole vehicle cable comprehensive test device. BACKGROUND

[0002] In the production and manufacturing process of motor train unit, after the vehicle assembly is completed, firstly, the motor train unit whole vehicle cable connection correctness test, insulation performance test, voltage resistance performance test are carried out, and after the whole vehicle cable each test is qualified, the vehicle can be powered and the relevant functional test is carried out. The motor train unit whole vehicle cable performance and connection correctness not only affect the product quality, but also relate to the operation safety of motor train unit, therefore, in the production process of motor train unit, the whole vehicle cable each test must be carried out according to the relevant standard, and it is ensured that each performance index meets the standard requirement.

[0003] The existing technology test method of motor train unit whole vehicle cable connection correctness is generally that the test personnel uses the multimeter or buzzer to carry out manual test, and generally two test personnel cooperate to complete. For example, in the process of carrying out the connection correctness test of a cable from the vehicle to the vehicle, first, the vehicle body is regarded as the ground, the operator A under the vehicle uses the short cable to short the measured cable and the ground (vehicle body), then informs the operator B in the vehicle through the intercom, then the operator B uses the multimeter or buzzer to test the connection performance of the measured cable and the ground (vehicle body) in the vehicle, and records the test result. The method has large labor intensity, low work efficiency, and cannot test the line short circuit problem. In addition, many wiring points are densely distributed on the same connector or electronic row, and the problems such as missing measurement are caused.

[0004] The existing technology test method of motor train unit whole vehicle cable insulation performance and voltage resistance performance is generally that all the cables of the vehicle are grounded (vehicle body) first, then the insulation resistance tester and voltage resistance tester are used to test in batches. For example, in the test process, the multiple or a bundle of cables to be measured are grounded, then are connected to the voltage resistance tester, the voltage resistance performance of the cable is measured, and the test result is recorded. After the voltage resistance performance test, the cable is connected to the insulation resistance tester, the insulation performance of the cable is measured, and the test result is recorded. The method has large labor intensity, low work efficiency, and because the test of a bundle of lines is carried out at the same time, the insulation and voltage resistance problems between the cables of the bundle of lines cannot be tested.

[0005] The test scheme of automobile cable is different from that of motor train unit, because the number of automobile cable is less, the wire diameter is thin, and the length is short, generally, the cable is pre-assembled first, then is inserted into the equipment to carry out automatic test, and after the test is completed, is installed on the automobile. But because the number of motor train unit cable is more, part of the wire diameter is thick, the wiring end is distributed at each position of the vehicle, and the path penetrates the vehicle body type cavity floor sandwich, cannot be pre-assembled and inserted into the equipment to carry out automatic test like the automobile cable.

[0006] In summary, the test scheme of the existing technology of the EMU cable needs three test processes, is manually operated by using multiple devices, has high labor intensity, low work efficiency, long test period, cannot test the problems such as interline short circuit, cannot test the insulation and voltage resistance between the cables of a bundle, and needs manual registration of test results.
