Description

Technical Field

[0002] High-voltage disconnectors are usually located on the ground of a substation. The disconnector is connected with fittings through cables, and the fittings are fixed on the overhead cable to complete the connection between the overhead cable and the disconnector. The high-voltage switch contact refers to the contact in the high-voltage switch, which is used to connect or disconnect in the high-voltage circuit. Before the high-voltage switch contact is used, it is necessary to detect the state such as the resistance change between the contacts to ensure that the switch contact can operate safely during use.

[0003] At present, the horizontal plate and the vertical plate on the switch contact are connected by welding. In order to ensure the subsequent use, it is necessary to detect the resistance of the switch contact after connection. During the detection, only the detection head touches the horizontal plate and the vertical plate to complete the detection, and only one detection is carried out, resulting in less detection data, which leads to accidental errors in the detection results, and further affects the accuracy of the detection results; And during the detection process, it is conveyed by a synchronous belt, and it is impossible to ensure that the switch contact accurately stays in the area to be detected during the conveying process, so that the staying position will deviate from the area to be detected, and then it is necessary to adjust the position of the switch contact back and forth, thus affecting the accurate feeding of the switch contact and resulting in low feeding efficiency and detection efficiency.

A first detection head 25 and a second detection head 39 are respectively and fixedly penetrated through the first adjustment plate 17 and the second adjustment plate 22. The first detection head 25 and the second detection head 39 are respectively used to contact the horizontal plate and the vertical plate on the switch contact 3, so as to detect the resistance of each position of the horizontal plate and the vertical plate; As Figure 4 , Figure 7 , Figure 8 shown, the blowing and cleaning mechanism includes a blowing groove 40 opened on the first detection head 25 and the first electric cylinder 29, and includes a second blower 28 and a first blower 24 fixedly connected to the first moving plate 14 and the second moving plate 19.

[0018] As Figure 1 , Figure 6 shown, the spacing control mechanism includes a rotating shaft 12 rotatably penetrating through the fixing plate 13. Synchronous wheels 7 are fixedly connected to the outer walls of the two rotating shafts 12. The two synchronous wheels 7 are connected by a synchronous belt 5.

The second driving shaft 23 is fixedly connected to a second adjusting plate 22. The second fixed block 26 fixes and limits the second electric push rod 27, so that the second moving plate 19 moves in the direction of approaching or departing from the synchronous belt 5, thereby adjusting the position of the second detection head 39 and performing multiple tests to improve the accuracy of the test results. The second motor 21 drives the second driving shaft 23 to rotate, and the second detection head 39 lands on the cross plate of the switch contact 3, and can also perform preliminary clamping and fixing on the switch contact 3.

One end of the second side plate 38 close to the moving bottom plate 32 is fixedly connected with a second electric cylinder 37.

The middle part of the top end of the moving bottom plate 32 is fixedly inlaid with a hydraulic rod 41. The telescopic end of the hydraulic rod 41 is fixedly connected with a lifting plate 31. Guide rods are fixedly connected to both sides of the bottom end of the lifting plate 31 corresponding to the hydraulic rod 41, and the two guide rods are inserted into the top end of the moving bottom plate 32. The second side plate 38 fixes and limits the second electric cylinder 37, and drives the moving bottom plate 32 to move back and forth along the edge of the synchronous belt 5, so that the first detection head 25 contacts the vertical plate on the switch contact 3. The hydraulic rod 41 can drive the lifting plate 31 to move up and down, so the position of the first detection head 25 can be changed.

[0023] As Figure 2 , Figure 6 , Figure 8 shown, a first side plate 30 is fixedly connected to the outer side of the top end of the lifting plate 31.

The first side plate 30 fixes and limits the first electric cylinder 29, and the first electric cylinder 29 drives the first moving plate 14 to move in a direction close to or away from the synchronous belt 5 to complete the position adjustment.

[0024] As Figure 1 , Figure 7 , Figure 8 shown, a resistance tester 8 is fixedly connected to the other side of the top end of the fixed base 1 corresponding to the first moving block 9. The resistance tester 8 is connected to the first detection head 25 and the second detection head 39 through cables respectively. The resistance tester 8 tests each position of the switch contact 3, so as to improve the accuracy of the test result, and can test whether the welding is tight to ensure normal use in the follow-up.

[0025] Working principle: Before conveying, the synchronous controller controls the electric telescopic rod 33 to move synchronously and drives the fixed ring 34 to move towards the vertical plate 4, thereby driving the stop rod 35 to move and releasing the limit on the limit plate 36. At this time, the driving motor 6 is started to drive the rotating shaft 12 on one side to rotate, and the rotating shaft 12 on one side drives the synchronous pulley 7 on one side to rotate. Through the synchronous belt 5, the synchronous pulleys 7 on both sides can rotate synchronously, so that the switch contact 3 can be conveyed by the placement frame 2. At this time, when the limit plate 36 rotates, the electric telescopic rod 33 is started in the reverse direction to push the fixed ring 34 and the stop rod 35 to move towards the fixed plate 13 and make the stop rod 35 extend, so as to block the rotating limit plate 36 and make the position of the switch contact 3 to be detected accurately reach the area to be detected, thus avoiding excessive path walking and further avoiding the situation of back-and-forth adjustment, and then realizing precise feeding, improving the feeding efficiency and the detection efficiency; After that, the second motor 21 is started to drive the second drive shaft 23 to rotate. The second drive shaft 23 drives the second adjusting plate 22 to rotate and makes the second detection head 39 contact the cross plate of the switch contact 3. When contacting, the first blower 24 is started to convey air through the hose to the air blowing groove 40 on the second detection head 39, so as to blow and sweep the area to be contacted between the second detection head 39 and the cross plate of the switch contact 3, prevent dust and other impurities on the cross plate from affecting the contact, and avoid affecting the accuracy of the subsequent detection results. Similarly, the first motor 15 can be started to drive the first drive shaft 16 and the first adjusting plate 17 to rotate, and the second electric cylinder 37 is started to push the moving bottom plate 32 to move, and drives the structure on the moving bottom plate 32 to move synchronously, and makes the first detection head 25 contact the cross plate of the switch contact 3. When contacting, the second blower 28 is started to convey air through the hose to the air blowing groove 40 on the first detection head 25, which can blow and sweep the area to be contacted between the first detection head 25 and the cross plate of the switch contact 3, prevent the influence of dust and other impurities on the contact, and avoid affecting the accuracy of the subsequent detection results; When detecting, the resistance tester 8 can monitor the resistance between the cross plate and the vertical plate of the switch contact 3 and whether they are tightly connected. At this time, the first electric push rod 10 is started to push the first moving block 9 to move, and at the same time drives the structure on the first moving block 9 to move synchronously. At this time, the position of the second detection head 39 on the cross plate of the switch contact 3 can be changed. Similarly, the first electric cylinder 29 is started to push the first moving plate 14 to move, and the hydraulic rod 41 pushes the lifting plate 31 to move, so that the position of the first detection head 25 on the vertical plate of the switch contact 3 can be changed. Therefore, during the detection process, the resistance of multiple positions of the switch contact 3 can be detected, and the detection results can be comprehensively analyzed to avoid accidental errors, so as to ensure the accuracy of the detection results.
