Description

Technical Field

[0001] The present invention belongs to the technical field of reactor detection, and particularly relates to a reactor compressive strength 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 jolted and squeezed during transportation, being collided during installation, and being affected by electromagnetic force, environmental stress, etc. during operation. If the compressive strength is insufficient, it will cause deformation of the internal structure and damage to the insulation, leading to problems such as short circuits and fault tripping, seriously threatening the stability of power supply. Therefore, it is crucial to carry out compressive strength detection on the reactor to ensure its structural integrity and performance stability.

[0003] Currently, when performing compressive strength detection on the reactor, usually a pressing structure is used to apply pressure to the outer wall of the reactor, and then it is measured whether the compressive performance of the reactor meets the requirements, such as a reactor compressive strength detection device disclosed in the patent publication number CN220982926U;

[0004] The operating environment of the reactor is complex, and the insulating sleeve is affected by electromagnetic force, mechanical stress, temperature change and chemical corrosion for a long time (the insulating sleeve is used to wrap the reactor coil, playing the roles of insulation, isolation and protection, preventing electric leakage and short circuit, refer to Figure 8 , in the figure, the label L is the reactor main body, and the 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 electric breakdown, but also lead to short circuit between coils or short circuit to the ground, causing equipment failure, power outage, and even endangering personal safety. Moreover, different working conditions have different requirements for the strength of the insulating sleeve. Through detection, potential hazards can be discovered in advance, ensuring the reliable operation of the reactor and extending its service life. However, currently, the strength detection is usually carried out before the assembly of the insulating sleeve, and only some points are selected for strength detection. This will not only result in the detection result not being close to the actual situation, but also the detection range is small and the representativeness is insufficient. Summary of the Invention

[0036] A plurality of heating units 10 are all arranged inside the corresponding pressing units 8 and are used to heat each pressing point. Each heating unit 10 includes an installation groove 101 opened at the end of the conical heat-insulating pressing head 84, and an electric heating head 102 is fixedly installed at the bottom of the installation groove 101.

[0037] A plurality of temperature measurement and screening mechanisms 11 are all installed inside the corresponding heating units 10, and the control cabinet 3 controls the corresponding oil supply unit 9 and pressing unit 8 to work according to the electrical signals output by each temperature measurement and screening mechanism 11.

[0038] Two vibration units 12 are both installed inside the corresponding detection seats 4, and the two vibration units 12 are both communicated with the corresponding U-shaped cavities 7.

Each electromagnetic push rod 124 is electrically connected to the control cabinet 3. A limiting frame plate is installed inside the oil cavity 121 to limit and support the piston push plate 123, so as to avoid damage to the electromagnetic push rod 124 under excessive hydraulic pressure when the hydraulic station 91 transports hydraulic oil into the U-shaped cavity 7.

[0039] An electromagnetic ring 13 is fixedly inserted at one end of each cylinder seat 81 away from the U-shaped cavity 7 on the same side. An iron ring 14 corresponding to the position of the electromagnetic ring 13 is fixedly connected to one end of each conical heat-insulating pressing head 84 close to the cylinder seat 81 on the same side. The electromagnetic ring 13 is electrically connected to the control cabinet 3. After the electromagnetic ring 13 is powered on, it can attract the iron ring 14 to move, so as to assist the spring 85 to move the pressing piston 82 back to its original position.

[0040] The operating principle of the present invention is described as follows: The compressive strength test of the reactor is carried out in a constant temperature chamber where the temperature is 25°C ± 1°C. Then, the assembled reactor is placed on the mounting table 2. Subsequently, the mounting holes at the bottom of the reactor are aligned with the threaded holes reserved on the mounting table 2, and the reactor is locked on the mounting table 2 by locking parts such as bolts (refer to Figure 2 , the dashed part in the figure represents the reactor), and then the control cabinet 3 is started;

[0041] After the control cabinet 3 is started, it will control the electric push rod 62 to work for a fixed time of 15 seconds. After the fixed-time work of the electric push rod 62 ends, the opposite ends of the two detection seats 4 abut against each other, and each U-shaped groove 5 is sleeved on the outside of the corresponding insulating sleeve of the reactor (refer to Figure 7 , Figure 7 , the dashed part in the figure represents the insulating sleeve of the reactor). Subsequently, the control cabinet 3 controls each electromagnetic push rod 124 to be energized to work, and controls each pressure application electric control valve 86 to be fully energized and opened. When each electromagnetic push rod 124 is energized, it can push the pressure application piston 82 at the corresponding position towards the direction of the U-shaped cavity 7 on the same side, so as to squeeze the hydraulic oil inside the oil cavity 121 on the same side into the U-shaped cavity 7 (both the U-shaped cavity 7 and the oil cavity 121 are filled with hydraulic oil initially). At this time, the pressure inside the U-shaped cavity 7 increases, so each pressure application piston 82 will move in the direction away from the U-shaped cavity 7 on the same side, so as to drive the conical heat-insulating pressure application head 84 to impact the side wall of the insulating sleeve of the reactor through the pressure application rod 83. After the electromagnetic push rod 124 works for 3 seconds, the control cabinet 3 controls the electromagnetic push rod 124 to cut off the power, and at the same time controls each electromagnetic ring 13 to be energized to work. At this time, each electromagnetic ring 13 will generate a magnetic suction force on the iron ring 14 on the same side. With the cooperation of the acting force of each spring 85 for the rebound and reset of the pressure application piston 82 on the same side, each pressure application 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 cut off the power, and controls the electromagnetic push rod 124 to work again. After the electromagnetic push rod 124 works for 3 seconds, it cuts off the power, and then the electromagnetic ring 13 works for 3 seconds and cuts off the power. The two work alternately. The electromagnetic push rod 124 and the electromagnetic ring 13 are energized 25 times in total, so as to impact the side wall of the insulating sleeve of the reactor multiple times. Under the external force generated by the impact vibration, the microscopic structure inside the insulating sleeve changes, such as the expansion of small cracks and the separation of the delamination part, 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 operation of the two hydraulic stations 91, and controls the energization and opening of the oil inlet electro-control valve 95. At this time, the hydraulic stations 91 can transport hydraulic oil into the oil tank 93 through the oil delivery hoses 92. Under the action of the increasing hydraulic oil, each pressure piston 82 moves again towards the insulating sleeve of the reactor. After the hydraulic stations 91 work for 10 seconds, the control cabinet 3 controls the hydraulic stations 91 to stop working, controls the oil inlet electro-control valve 95 to de-energize and close, and controls each pressure electro-control valve 86 to de-energize. At this time, each conical heat-insulating pressure head 84 will abut against the outer side 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 fixed time. Each electric heating head 102 will be energized and generate heat. The generated heat is conducted to the insulating sleeve through the insulating heat-conducting block 111 on the same side, and the heating temperature is 75°C. After the electric heating head 102 works, all the inspection points of the insulating sleeve of the reactor are heated. After the electric heating head 102 works for 1 minute, the control cabinet 3 waits for 2 minutes and then 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 there are defects such as cracks and bubbles inside the side wall of the insulating sleeve that affect the strength, since there is air inside the cracks and bubbles, and the heat transfer efficiency of air is lower than that of the insulating sleeve, when the temperature conducted by the electric heating head 102 reaches the positions of cracks and bubbles, etc., it will be blocked. Therefore, the heat conduction efficiency of the position with strength-affecting defects is relatively low. Therefore, within 1 minute when the electric heating head 102 works and the 2 minutes when the control cabinet 3 waits, the heat dissipation efficiency at this position is relatively low. Thus, when the control cabinet 3 controls the temperature probe 112 to work, the temperature probe 112 detects that the temperature of the insulating heat-conducting block 111 on the same side is relatively high (since the heat dissipation efficiency of the defective position is relatively low, the heat accumulates at this position, so the temperature of the insulating heat-conducting block 111 is relatively high). At this time, this temperature probe 112 will feedback an electrical signal to the control cabinet 3 (the trigger temperature threshold for the temperature probe 112 to feedback the electrical signal can be set according to the material of the insulating sleeve used. For example, the temperature measured under the same conditions by an insulating sleeve with qualified strength. Assume that the insulating sleeve of the reactor uses epoxy resin material with a thickness of 5 mm and the strength meets the relevant standard requirements. Under the above-mentioned heating, waiting and detection processes of the electric heating head 102, after multiple repeated tests, it is determined that when the trigger temperature threshold for the temperature probe 112 to feedback the electrical signal is set to 60°C, it can effectively distinguish whether the insulating 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-conducting block 111 on the same side stabilizes at about 55°C and does not reach the threshold. However, when there are defects such as cracks and bubbles, the temperature of the insulating heat-conducting block 111 at this position will reach 58°C and 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 insulating sleeve), and 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 resistance detection work according to the recorded electrical signals fed back by each temperature probe 112. At this time, the control cabinet 3 will perform pressure resistance detection on the points that may have defects in sequence (for example, pre-number multiple temperature probes 112 on the same side, and then perform pressure resistance detection on each point in sequence from small to large according to the number of the temperature probe 112 corresponding to the recorded electrical signals). When the control cabinet 3 starts the pressure resistance detection 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 simultaneously performs a timed oil delivery operation. The hydraulic station 91 delivers 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 enters 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 insulating 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 to the side wall of the insulating sleeve through the pressure rod 83 and the conical insulating pressure head 84 gradually increases. If the compressive strength of this point is insufficient, this point will be concavely deformed, and the pressure piston 82 will move at this time. , thereby touching and pressing 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 indicates 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 points are marked to facilitate subsequent personnel to check the defective points and trace the causes of the defects). On the contrary, when the compressive strength of the point meets the use requirements, the pressure piston 82 cannot touch and press the pressure switch 87 on the same side to close, 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). (set up), after the timing work of the hydraulic station 91 is completed, 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 in 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 this point to shut off the power and immediately end the compressive strength test of the point, and then follow the sequence and repeat the above steps to perform the compressive strength test of the next point 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 the 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.
