Description
Technical Field
[0001] The invention relates to the technical field of high-voltage test brackets, in particular to a multi-angle adjustable high-voltage test bracket. Background Art
[0002] The power frequency AC withstand voltage test is the most stringent and effective method to test the insulation strength of the test product and its ability to withstand various overvoltages. It is of great significance to ensure the safe operation of high-voltage electrical equipment. As the core unit in the low-voltage distribution room, the withstand voltage test of the internal circuit breaker, current transformer, support insulator and busbar of the high-voltage switch cabinet is a key step in the evaluation of the insulation status of the equipment. In daily practical work, thin iron wire or copper wire with excellent conductive performance and convenient winding is usually used to replace the high-voltage lead wire. Except for the trolley switch, the busbar, the primary cable head of the outgoing line, and the knife switch contacts on the bus side of the cabinet are all inside the switch cabinet or in the cable trench. When conducting a high-voltage test on them, due to the cabinet steel In order to increase the distance between the high-voltage leads and the non-test equipment, the high-voltage end of the booster and the test equipment are usually not on the same horizontal plane. The angle is often changed by padding with insulating materials and hanging leads in the air. The high-voltage leads cannot be reliably fixed during the boosting process. When the test high voltage reaches a certain value, discharge may occur due to insufficient safety distance between the leads and the equipment casing, non-test phase equipment, and grounding wires, which brings certain safety hazards to the entire high-voltage test work, reduces on-site work efficiency, and even damages internal equipment. For this reason, an adjustable high-voltage test bracket for the switch cabinet is designed to effectively solve the problem of inconvenient connection and unreliable fixation of the test leads.

[0019] Working principle: In this embodiment, the present invention also proposes a method for using a multi-angle adjustable high-voltage test stand, comprising the following steps: Step 1: First, rotate the positioning bolts 12 at both ends, so that the positioning screws 11 at both ends can be controlled to move in the sliding openings of the connecting plate 10, and then move the installation tubes 13 at both ends outward to expose the bottom surface of the positioning shell 2, and then install the magnetic block 8 inside the rubber sleeve 7, and then push the connecting rod 6 from the lower end of the vertical pipe 1, and then control the adjustment cylinder 5 to rotate. The upper end of the connecting rod 6 is provided with a threaded groove, and the inner wall of the adjustment cylinder 5 is provided with a thread. When the adjustment cylinder 5 rotates, the connecting rod 6 is controlled to move upward, and then the magnetic block 8 is controlled to move upward. At this time, the adsorption assembly is installed; Step 2: Then push the first positioning block 23 into the first installation groove opened at the upper end of the adjusting cylinder 5, and then push the first fixing rods 25 on both sides of the first positioning plate 24 into the first positioning grooves opened on both sides of the first fixing ring 21, and then rotate the first fixing block 26 at the lower end of the first fixing rod 25, and the first fixing rod 25 is threadedly connected with the first fixing block 26, so that the first positioning plate 24 is fixed to the upper end of the adjusting cylinder 5, and the second spring 22 is in a compressed state at this time; when the first positioning plate 24 is installed, the rotating cylinder 28 is installed, and then the connecting shaft 33 is installed; when multiple connecting shafts 33 need to be installed, it is only necessary to push the new first positioning block 23 into the second installation groove at the other end of the fixed connecting shaft 33; Step 3, after one or more connecting shafts 33 are installed, push the second positioning block 40 into the second installation groove opened at the other end of the last connecting shaft 33, and then push the second fixing rods 42 at both ends of the second positioning plate 41 into the second positioning grooves opened at both ends of the second fixing ring 38, and then rotate the second fixing block 43 at the lower end of the second fixing rod 42, and the second fixing rod 42 is threadedly connected with the second fixing block 43, and when the second fixing block 43 is rotated, the second positioning plate 41 is fixed, and then the connection box 44 is installed; Step 4, when the device is connected, the positioning shell 2 is abutted against the switch cabinet, and then the adjustment plates 20 on both sides are pressed downward, and one end of the triangular plate 19 is rotatably connected to the moving rod 16, and the other end is abutted against the shell 14. When the adjustment plate 20 is pressed down, the moving rod 16 is controlled to rise. At this time, the first spring 17 is in a compressed state, and then the middle part of the rubber disc 15 is concave inward, so that the rubber disc 15 is adsorbed on the switch cabinet, and then the adjustment cylinder 5 is rotated, and the adjustment cylinder 5 is threadedly connected with the connecting rod 6, so as to control the magnetic block 8 to move outward, and then control the magnetic block 8 to be adsorbed on the switch cabinet; when the angle adjustment is required, the connecting shaft 33 is pressed toward one end, so that the spline shaft 34 is disengaged from the spline groove 29, and the connecting shaft 33 can be rotated at this time. The connecting shaft 33 is rotated according to specific needs to complete the purpose of angle adjustment. When the angle is adjusted, the connecting shaft 33 is released and the spline shaft 34 is pushed into the spline groove 29 by the third spring 31, so that the angle is fixed; Step five, when the angle is determined, pass the lead through the hook ring 47. When the lead tension is too large, the hook ring 47 will deflect in the direction of the lead tension, thereby buffering the force of the lead on the hook ring 47 and avoiding the lead from breaking. At this time, the torsion spring 45 is in a compressed state; when the test is completed, turn the adjustment cylinder 5 to control the magnetic block 8 to move inward, and then pull the adjustment plate 20 upward, and push the moving rod 16 downward through the first spring 17, so that the rubber disc 15 is no longer adsorbed on the switch cabinet, and then remove the device, disassemble it in sequence and store it well.
