Description

Technical Field

[0001] The invention belongs to the technical field of reactor detection, and in particular relates to a reactor withstand voltage detection device. Background Art

[0002] In the operation of the power system, the reactor plays a key role. It faces many working conditions, such as being subjected to bumps and squeezing during transportation, collisions during installation, and electromagnetic forces and environmental stresses during operation. If the pressure resistance is insufficient, the internal structure will be deformed and the insulation will be damaged, causing short circuits, fault tripping and other problems, which seriously threaten the stability of the power supply. Therefore, it is crucial to carry out pressure resistance testing on the reactor to ensure its structural integrity and stable performance.

[0003] Currently, when performing pressure resistance testing on a reactor, a pressure-applying structure is usually used to apply pressure to the outer wall of the reactor, and then the pressure resistance of the reactor is measured to determine whether it meets the requirements for use. For example, a reactor pressure resistance testing device disclosed in patent publication number CN220982926U;

[0004] The operating environment of the reactor is complex, and the insulation sleeve is affected by electromagnetic force, mechanical stress, temperature change and chemical corrosion for a long time (the insulation sleeve is used to wrap the reactor coil to insulate, isolate and protect it to prevent leakage and short circuit. Figure 8 In the figure, label L is the reactor body, and label G is the insulating sleeve). Once the strength of the insulating sleeve is insufficient, it may crack or deform, resulting in a decrease in insulation performance, which will not only cause electrical breakdown, but also cause phase-to-phase short circuit or short circuit to ground of the coil, causing equipment failure, power outage, and even endangering personnel safety. Moreover, different working conditions have different requirements for the strength of the insulating sleeve. Through testing, hidden dangers can be discovered in advance to ensure the reliable operation of the reactor and extend its service life. However, strength testing is usually carried out before the insulating sleeve is assembled, and only some points are extracted for strength testing. This not only makes the test results less practical, but also has a small detection range and lacks representativeness. Summary of the Invention

[0036] Multiple heating units 10 are arranged inside the corresponding pressure units 8 for heating each pressure point. Each heating unit 10 includes a mounting groove 101 opened at the end of the conical insulation pressure head 84, and an electric heating head 102 is fixedly installed at the bottom of the mounting groove 101. The electric heating head 102 is electrically connected to the control cabinet 3.

[0037] Multiple temperature measuring and screening mechanisms 11 are installed inside the corresponding heating units 10, and the control cabinet 3 controls the operation of the corresponding oil supply unit 9 and the pressure unit 8 according to the electrical signals output by each temperature measuring and screening mechanism 11. Each temperature measuring and screening mechanism 11 includes an insulating heat-conducting block 111 fixedly installed at the slot of the installation slot 101, and the insulating heat-conducting block 111 is located on the side wall of one side inside the installation slot 101.

After the temperature probe 112 detects that the temperature exceeds the threshold, it can feedback an electrical signal to the control cabinet 3. The temperature probe 112 mainly includes a thermistor and a feedback circuit. The thermistor is arranged on the side wall of the insulating heat-conducting block 111, and the feedback circuit is arranged inside the control cabinet 3.

[0038] Both vibration units 12 are installed inside the corresponding detection seat 4, and both vibration units 12 are connected to the corresponding U-shaped cavity 7. Both vibration units 12 include multiple oil chambers 121 opened on both sides of the detection seat 4, and each oil chamber 121 and the U-shaped cavity 7 on the same side are jointly provided with an oil hole 122. A piston push plate 123 is slidably arranged inside each oil chamber 121. Two electromagnetic push rods 124 are fixedly inserted into the cavity wall of each oil chamber 121, and the telescopic end of each electromagnetic push rod 124 is fixedly connected to the side wall of the piston push plate 123 on the same side. Each electromagnetic push rod 124 is electrically connected to the control cabinet 3. A limit frame plate is installed inside the oil chamber 121 for limiting the support of the piston push plate 123 to prevent the electromagnetic push rod 124 from being damaged by excessive hydraulic pressure when the hydraulic station 91 transports hydraulic oil to the inside of the U-shaped cavity 7.

[0039] An electromagnetic ring 13 is fixedly connected to the end of each cylindrical seat 81 away from the U-shaped cavity 7 on the same side, and an iron ring 14 corresponding to the position of the electromagnetic ring 13 is fixedly connected to the end of each conical heat-insulating pressure head 84 close to the cylindrical seat 81 on the same side. The electromagnetic ring 13 is electrically connected to the control cabinet 3. When the electromagnetic ring 13 is energized, it can attract the iron ring 14 to move, thereby assisting the spring 85 to move the pressure piston 82 back and reset.

[0040] The operating principle of the present invention is described as follows: the pressure test of the reactor is carried out in a constant temperature room at a temperature of 25°C ± 1°C, and then the assembled reactor is placed on the mounting table 2, and then the mounting hole on the bottom of the reactor is aligned with the threaded hole reserved on the mounting table 2, and the reactor is locked on the mounting table 2 by means of bolts or other locking parts (refer to Figure 2 , the dotted line portion in the figure represents the reactor), then, start the control cabinet 3;

[0041] After the control cabinet 3 is started, the electric push rod 62 will be controlled to work for 15 seconds. After the electric push rod 62 finishes working, the two ends of the two detection seats 4 are against each other, and each U-shaped groove 5 is clamped on the outside of the insulating sleeve of the corresponding reactor (refer to Figure 7 , Figure 7 The dotted line part represents the insulating sleeve of the reactor), then, the control cabinet 3 controls each electromagnetic push rod 124 to be energized and works, and controls each pressure electric control valve 86 to be energized and opened. When each electromagnetic push rod 124 is energized, it can push the pressure piston 82 at the corresponding position to move toward the U-shaped cavity 7 on the same side, so that the hydraulic oil inside the oil cavity 121 on the same side can be squeezed into the U-shaped cavity 7 (the U-shaped cavity 7 and the oil cavity 121 are initially filled with hydraulic oil). At this time, the hydraulic pressure inside the U-shaped cavity 7 increases, so each pressure piston 82 will move in the direction away from the U-shaped cavity 7 on the same side, so that the conical heat-insulating pressure head 84 can be driven by the pressure rod 83 to hit the side wall of the insulating sleeve of the reactor. After the electromagnetic push rod 124 works for 3 seconds, the control cabinet 3 controls the electromagnetic push rod 124 to be de-energized, and at the same time When each electromagnetic ring 13 is energized, it controls the power supply of each electromagnetic ring 13. At this time, each electromagnetic ring 13 will generate a magnetic attraction force on the iron ring 14 on the same side. Under the force of each spring 85 on the rebound reset of the pressure piston 82 on the same side, each pressure piston 82 will quickly move back. After the electromagnetic ring 13 is energized for 3 seconds, the control cabinet 3 controls the electromagnetic ring 13 to be de-energized and controls the electromagnetic push rod 124 to work again. The electromagnetic push rod 124 is de-energized after working for 3 seconds, and then the electromagnetic ring 13 is de-energized after working for 3 seconds. The two work alternately. The electromagnetic push rod 124 and the electromagnetic ring 13 are energized 25 times in total, so that the side wall of the insulating sleeve of the reactor can be impacted multiple times. Under the external force generated by the impact vibration, the internal microstructure of the insulating sleeve changes, such as the expansion of small cracks and separation of the delamination, so that the possible defects inside the insulating sleeve can be exposed.

[0042] After the electromagnetic ring 13 finishes working, the control cabinet 3 controls the two hydraulic stations 91 to work and controls the oil inlet electric control valve 95 to be energized and opened. At this time, the hydraulic station 91 can deliver hydraulic oil to the inside of the oil tank 93 through the oil delivery hose 92. Under the action of the increased hydraulic oil, each pressure piston 82 moves again toward the insulating sleeve of the reactor. After the hydraulic station 91 works for 10 seconds, the control cabinet 3 controls the hydraulic station 91 to stop working, controls the oil inlet electric control valve 95 to be de-energized and closed, and controls the pressure electric control valves 86 to be de-energized. At this time, each conical heat-insulating pressure head 84 will abut against the outer wall of the insulating sleeve of the reactor.

[0043] Subsequently, the control cabinet 3 controls each electric heating head 102 to work for 1 minute at a time. Each electric heating head 102 will be powered on to generate heat. The generated heat will be transferred to the insulating sleeve through the insulating heat-conducting block 111 on the same side. The heating temperature is 75°C. After the electric heating head 102 works, each inspection point of the insulating sleeve of the reactor is heated. After the electric heating head 102 works for 1 minute, the control cabinet 3 waits for 2 minutes and starts each temperature probe 112. Each temperature probe 112 will detect the temperature of the insulating heat-conducting block 111 on the same side and convert the detected temperature into an electrical signal and output it to the control cabinet 3. When the side wall of the insulating sleeve is When there are defects such as cracks and bubbles that affect the strength inside, there is air inside the cracks and bubbles, and the heat transfer efficiency of air is lower than the heat transfer efficiency of the insulating sleeve. Therefore, the temperature heated by the electric heating head 102 will be blocked when it is transmitted to the cracks, bubbles and other positions. Therefore, the heat conduction efficiency of the point where there is a defect affecting the strength is low. Therefore, when the electric heating head 102 works for 1 minute and the control cabinet 3 waits for 2 minutes, the heat dissipation efficiency at this position is low. As a result, when the control cabinet 3 controls the temperature probe 112 to work, the temperature probe 112 detects that the temperature of the insulating heat conductive block 111 on the same side is high (due to the defective point). The heat dissipation efficiency is low, so the heat accumulates at this point, so the temperature of the insulating heat conductive block 111 is high). At this time, the temperature probe 112 will feedback an electrical signal to the control cabinet 3 (the trigger temperature threshold of the temperature probe 112 feedback electrical signal can be set according to the insulating sleeve material used. For example, the temperature is measured under the same conditions by an insulating sleeve with strength that meets the requirements. Assuming that the insulating sleeve of the reactor is made of epoxy resin with a thickness of 5mm and a strength that meets the requirements of relevant standards, under the above-mentioned heating, waiting and detection process of the electric heating head 102, after repeated tests, it is determined that when the temperature probe 112 feedbacks the electrical signal When the trigger temperature threshold of the signal is set to 60°C, it can effectively distinguish whether the insulation sleeve has defects. That is, under normal circumstances, after the electric heating head 102 works for 1 minute and the control cabinet 3 waits for 2 minutes, the temperature probe 112 detects that the temperature of the insulating heat conductive block 111 on the same side is stable at around 55°C, which does not reach the threshold. However, when there are defects such as cracks or bubbles, the temperature of the insulating heat conductive block 111 at that point will reach 58°C or above. At this time, the temperature probe 112 will feedback an electrical signal to the control cabinet 3 to accurately judge the quality status of the insulation sleeve. The control cabinet 3 will record the electrical signals output by each temperature probe 112;

[0044] After the control cabinet 3 controls each temperature probe 112 to work for 7 seconds, the control cabinet 3 will control each temperature probe 112 to stop working, and start the pressure test work according to the recorded electrical signals fed back by each temperature probe 112. At this time, the control cabinet 3 will perform pressure tests on the points that may have defects in sequence (for example, multiple temperature probes 112 on the same side are numbered in advance, and then pressure tests are performed on each point in sequence from small to large according to the temperature probe 112 numbers corresponding to the recorded electrical signals). When the control cabinet 3 starts the pressure test work on one of the points, the control cabinet 3 will control the corresponding pressure electric control valve 86 and the oil inlet electric control valve 95 of the oil tank 93 to be energized and opened, and control the liquid The pressure station 91 performs the timed oil delivery work synchronously. The hydraulic station 91 will deliver hydraulic oil to the U-shaped cavity 7 in the detection seat 4 on the same side through the oil delivery hose 92. The hydraulic oil will enter the corresponding cylindrical seat 81, thereby pushing the pressure piston 82 at this position to continue to move toward the insulating sleeve of the reactor. Since the conical insulation pressure head 84 is blocked by the side wall of the insulating sleeve of the reactor, the pressure piston 82 cannot move. As the amount of oil delivered to the U-shaped cavity 7 by the hydraulic station 91 increases, the pressure applied by the pressure piston 82 on the side wall of the insulating sleeve through the pressure rod 83 and the conical insulation pressure head 84 gradually increases. If the compressive strength of this point is insufficient, this point will appear concave deformation, and at this time the pressure piston 82 will move , thereby touching the pressure switch 87 on the same side, so that the pressure switch 87 is closed, and the pressure switch 87 will immediately feedback an electrical signal to the control cabinet 3, which means that the compressive strength of the point is insufficient, and the control cabinet 3 will record the defect information (for example, a three-dimensional simulated reactor graphic is displayed on the display screen of the control cabinet 3 itself, and then the relevant defective point is marked to facilitate subsequent personnel to check the defective point and trace the cause of the defect). On the contrary, when the compressive strength of the point meets the use requirements, the pressure piston 82 cannot touch and close the pressure switch 87 on the same side, which means that the compressive strength at the position meets the use requirements (wherein, the time for the hydraulic station 91 to work regularly can be adjusted according to the requirements for the compressive strength of the insulating sleeve). (Line setting), after the hydraulic station 91 finishes its timed work, the control cabinet 3 will control the oil inlet electric control valve 95 to close, and control the oil return electric control valve 97 to open. At this time, the excess hydraulic oil inside the U-shaped cavity 7 will flow back to the hydraulic station 91. After the oil return electric control valve 97 is energized for 10 seconds, the control cabinet 3 controls the pressure electric control valve 86 at that point to shut down, and then ends the compressive strength test of that point. Then, the compressive strength test of the next point is performed in sequence and the above steps are repeated until the compressive strength test of all the test points is completed. Then, the control cabinet 3 will control the electric push rod 62 to perform a timed return work, so that the two test seats 4 move back and reset. At this point, the test work of the reactor is completed.
