The dynamic test process of the power transformer top Bo vibration testing device that the invention process obtains is as follows:
1, as shown in Fig. 1,8, start master cylinder, make its telescopic head jack-up shaking table vertically upward, so the sliding part of shaking table through its edge along 4 slip guide pillars, slowly rise, until arrive the extreme higher position that meets top Bo Oscillation Amplitude in test;
2, as shown in Figure 2, because being provided with vertically to microswitch in the extreme higher position of shaking table, when a side of shaking table upper surface is touched vertically to microswitch, now vertically to microswitch, link on the one hand level to retraction microswitch, through being matched with the solenoid valve of 4 auxiliary oil cylinder oil circuits, make the telescopic head of 4 auxiliary oil cylinder oil circuits along level to retraction, thereby drive 4 apical grafting posts to move to shaking table below along 4 horizontal guide rails, the shaking table that is fixed with tested power transformer of extreme higher position in test, apical grafting dwelling, on the other hand when 4 apical grafting post shift-in shaking table belows, starting apical grafting lives after shaking table, through being matched with the solenoid valve of master cylinder oil circuit, master cylinder telescopic head is vertically bounced back leave shaking table lower surface, until be returned to its upper surface lower than 4 reference positions of accepting post height,
3, when master cylinder telescopic head vertically bounces back to its upper surface soon lower than 4 positions of accepting post height, just 4 apical grafting posts of shift-in shaking table below move to shake-up level to stretching out in microswitch, through being matched with the solenoid valve of 4 auxiliary oil cylinder oil circuits, make the level of telescopic head of 4 auxiliary oil cylinder oil circuits to stretching out, thereby force 4 apical grafting posts to shift out shaking table below, so be fixed with the shaking table of tested power transformer, lose support, as Fig. 3, shown in 4, sliding part through its edge under important power effect hurtles down along 4 slip guide pillars, as shown in Figure 5, fall in the plane supporting to 4 apical grafting post upper surfaces, cause top Bo vibration, to this, complete the Bo vibration test process of once running.
4, repeat above-mentioned process of the test 1-3, carry out continuously top Bo vibration test process 2 times.Per minute carries out meeting the top Bo vibration test process that top Bo vibration frequency requires for several times continuously, to reach the top Bo vibration frequency of testing requirements; Vertical interval while meeting the extreme higher position of top Bo Oscillation Amplitude between the shaking table lower surface surface level concordant with 4 apical grafting post upper surfaces, is the top Bo Oscillation Amplitude of testing requirements.
The power transformer top Bo vibration testing device that the invention process obtains, has reached following beneficial effect through trying out:
From above-mentioned dynamic test process 1-4, can clearly illustrate, adjustment level is to bounce back microswitch and level to the level interval along horizontal guide rail of stretching out between microswitch, realize to control run the continuously number of times of Bo vibration test process of per minute, to reach the vibration frequency of testing requirements; Adjust the vertically fixed position at slip guide pillar to microswitch, realize and adjust the extreme higher position that shaking table arrives along the jacking of slip guide pillar, therefore vertical interval when extreme higher position between the shaking table lower surface surface level concordant with 4 apical grafting post upper surfaces is adjusted, to reach the Oscillation Amplitude of testing requirements, thereby reached with the frequency of regulation, make the vertical effect to top Bo vibration-testing with amplitude.
