Description

Technical Field

[0001] The present invention relates to the technical field of circuit breaker testing, and in particular to an intelligent circuit breaker instantaneous testing device and a testing method thereof. Background Art

[0002] The mechanism of the intelligent circuit breaker is located on the front of the circuit breaker. The mechanism adopts a five-link free release mechanism and is designed to store energy. During the use of the intelligent circuit breaker, the mechanism is always in the pre-energy storage position. As long as the circuit breaker receives a closing command, the circuit breaker can be closed instantly. The pre-energy storage release button or closing electromagnet is completed. Before the intelligent circuit breaker leaves the factory, it is necessary to use a test instrument to detect the intelligent circuit breaker. The existing test instrument detection principles are divided into two categories. The first category is to detect the intelligent circuit breaker's own operating program, and the second category is to detect whether the intelligent circuit breaker has a power outage or short circuit problem.

[0003] During the use of circuit breakers, abnormal sounds or noises are often encountered. The reasons for the abnormal sounds or noises are as follows: (1) The undervoltage coil is not reliably pulled in, resulting in abnormal sounds or noises; (2) The main circuit current is too large; (3) The power quality is poor, such as high-order harmonics, but the abnormal noise caused by this factor is usually relatively small; (4) The contact itself is faulty and causes poor contact, which causes excessive noise.

[0004] The above two types of detection methods also have the following defects: it is impossible to eliminate the influence of external factors and determine whether the intelligent circuit breaker itself (such as its own contact failure) by controlling the parameters of the power supply and load (specifically voltage parameters, current parameters, etc.), thereby being unable to ensure the accuracy of the test results.

[0074] Working principle: Installation steps of the test piece: First, place the sound insulation material 9 in the sink 26 to block the center hole 27, then place the intelligent circuit breaker 8 on the shock-absorbing pad 29 on the surface of the support platform 24, and then start the second driving part 41. The second driving part 41 drives the threaded tube 61 to rotate through the active gear ring 42, the driven gear 43 and the transmission gear 63. The rotating threaded tube 61 drives the pipe rack 64, the square rod 65 and the mobile rack 66 to descend through the threaded rod 62. First, one end of the square rod 65 enters the longitudinal guide rail 251 along the inclined guide rail 252. At this time The reverse force provided by the inclined guide rail 252 drives the square rod 65 to move toward the direction close to the intelligent circuit breaker 8 and the sound insulation material 9. When the pressure seat 67 and the pressure plate 68 are respectively located above the intelligent circuit breaker 8 and the sound insulation material 9, one end of the square rod 65 just enters the longitudinal guide rail 251. When the second driving unit 41 continues to control the pressure seat 67 and the pressure plate 68 to descend, the pressure seat 67 and the pressure plate 68 can respectively fix the positions of the intelligent circuit breaker 8 and the sound insulation material 9, and electrically connect the power module 13 and the load module 14 to the terminal 81 of the intelligent circuit breaker 8 through the wire 15.

[0075] Steps for entering the box for testing: Use the first driving unit 21 to control the flap 22 to rotate 180 degrees around the central tube 23. At this time, the flap 22 seals the silent box 3, the intelligent circuit breaker 8 and the first noise collection module 5 are both located in the silent box 3, and the second noise collection module 7 is located outside the silent box 3.

[0076] Data collection steps: control the power module 13 and the load module 14 to start, use the computer module 12 to control the output voltage of the power module 13 and the operating power of the load module 14 respectively, use the first noise collection module 5 and the second noise collection module 7 to collect noise data respectively, the first noise collection module 5 stores the collected noise data in the signal storage unit, and when the first driving part 21 controls the flap 22 to rotate 180 degrees around the central tube 23 again, the first data sending unit transmits the noise data to the computer module 12 again, and the second noise collection module 7 transmits the collected noise data directly to the computer module 12.

[0077] Test result output steps: First, a noise database and a noise intensity level library of the intelligent circuit breaker 8 are established in the computer module 12. (1) The operation status information output process of the intelligent circuit breaker 8: The noise data collected by the first noise collection module 5 is input into the noise database of the intelligent circuit breaker 8. The noise database of the intelligent circuit breaker 8 includes a noise abnormality data template and an intelligent circuit breaker fault type. The noise abnormality data template and the intelligent circuit breaker fault type correspond to each other. The noise abnormality data template refers to the noise data after noise filtering and signal enhancement. After the noise data input into the noise database of the intelligent circuit breaker 8 is processed by noise filtering and signal enhancement, it is continued to be matched with the noise abnormality data template. When matching, the corresponding fault type information is output. The fault type includes overvoltage of the intelligent circuit breaker 8, overload of the intelligent circuit breaker 8 and loose parts of the intelligent circuit breaker, etc. Otherwise, the normal operation information of the intelligent circuit breaker 8 is output;

[0078] It should be noted that in order to ensure the accuracy of the operating fault information of the intelligent circuit breaker 8, the telescopic part 46 first controls the lifting ring 45, the rotating pin 44 and the driven gear 43 to descend, so that the driven gear 43 is disengaged from the active gear ring 42, and then controls the second driving part 41 to drive the active gear ring 42 to rotate a certain angle, so that the sound collecting position or angle of the first noise collection module 5 can be adjusted with the active gear ring 42 or the intelligent circuit breaker 8 as the axis, so that the noise data of the intelligent circuit breaker 8 can be collected from multiple directions, thereby expanding the diversity and richness of the noise data samples, thereby improving the accuracy of the noise detection results.

[0079] (2) The noise data collected by the second noise collection module 7 is input into the noise intensity level library. The noise intensity level library includes noise decibel size parameters and sound insulation level. The noise decibel size parameter is inversely proportional to the sound insulation level. When the noise data input into the noise intensity level library matches a certain noise decibel size parameter, the corresponding sound insulation level is output.

[0080] After the intelligent circuit breaker 8 is inspected, different sound insulation materials 9 can be inspected in turn, so that the sound insulation effect of the sound insulation material 9 on the outside of the intelligent circuit breaker 8 can be obtained while detecting the fault type of the intelligent circuit breaker 8, and then the sound insulation material 9 matching the model of the intelligent circuit breaker 8 can be selected.
