During work, first vacuum circuit breaker to be measured is bolted on testing stand, again the hold-down nut of the insulated tension pole on vacuum circuit breaker to be measured with vacuum circuit breaker proving installation is connected, proving installation is then connected with brake switch tester by data line, then starting switch tester, close a floodgate after first for vacuum circuit breaker to be measured energy storage, measure the excess of stroke of vacuum circuit breaker, average velocity, switching order and synchronism; Then again by vacuum circuit breaker separating brake to be measured, what test out vacuum circuit breaker opens distance, average velocity, separating brake order and synchronism.
Patent of the present invention is the proving installation that technician designs according to practical work experience, not only simple to operate, easy to connect, and main test result is accurate, reliable, stable, greatly can improve product quality and the productivity effect of vacuum circuit breaker.
Accompanying drawing explanation
Fig. 1 is the structural representation of vacuum circuit breaker performance parameter testing device of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In the past, operating personnel were when debugging vacuum circuit breaker, and what adopt traditional Universal drive support debugging vacuum circuit breaker opens distance, the excess of stroke and speed, but the data accuracy obtained is not high, and stability is also poor, and work efficiency is lower.Technician, through continuous test and study aborning, improves proving installation, has drawn a kind of brand-new vacuum circuit breaker performance parameter testing device.
As shown in Figure 1, a kind of vacuum circuit breaker performance parameter testing device, this device comprises: test board 1, fixed head 2, connecting rod 3, hold-down nut 6, sensor 7, support 8, data line 9, brake switch tester 10.Test board 1 is rectangular table structure, is provided with support 8 below its desktop.Fixed head 2 is platy structure, is fixed on the relevant position of support 8.One end of connecting rod 3 is connected with the insulated tension pole 4 on vacuum circuit breaker 5 to be measured by hold-down nut 6, and the other end is connected with sensor 7.Sensor 7 is fixed on fixed head 2.One end of data line 9 is connected with sensor 7, and the other end is connected with brake switch tester 10.Brake switch tester 10 can be placed on the table top of test board 1 as required, also can be placed on adjacent position.
During work, first vacuum circuit breaker 5 to be measured is fixed on above test board by set bolt, be connected with the hold-down nut 6 of vacuum circuit breaker performance parameter testing device by insulated tension pole 4 on vacuum circuit breaker 5 to be measured, proving installation is then connected with brake switch tester 10 by data line 9.Then starting switch tester 10, closes a floodgate after the first energy storage of vacuum circuit breaker 5 to be measured, then measures the excess of stroke, average velocity, switching order and synchronism; Then again by vacuum circuit breaker 5 separating brake to be measured, distance, average velocity, separating brake order and synchronism is tested out out.
The beneficial effect of proving installation of the present invention is adopted to be:
(1) the present invention uses the sensor of band data line to be connected with brake switch tester and accurately can measure the excess of stroke and time stroke family curve, and average velocity effective value when can test out combined floodgate is between 0.5 ~ 0.8m/s, the current peak of three-phase contemporaneous data, total kilometres and vacuum circuit breaker during splitting or integrating lock; Distance and average velocity effective value is opened between 0.9 ~ 1.2m/s when accurately can measure separating brake;
