Description

Technical Field

[0001] The present invention relates to the technical field of transformer detection, and in particular to a detection pipeline and a detection method for a high-voltage transformer. Background Art

[0002] High-voltage instrument transformers (HVTs) are used in 1kV to 220kV power systems to convert high voltages into low voltages or high currents into low currents for measurement, protection, and operation. They are primarily used in AC circuits to monitor the operation of electrical equipment and control systems. Their primary winding is typically called the primary winding, while their secondary winding is called the secondary winding. These windings supply power to the voltage and current coils of measuring instruments and relays, respectively, ensuring accurate monitoring of normal operation and fault conditions. The accuracy of measuring instruments and the reliability of protective relays are largely dependent on the performance of HVTs. Therefore, familiarity with their key characteristics is crucial for proper selection and use.

[0003] At present, in terms of testing the performance and errors of high-voltage transformers, the detection efficiency can be effectively improved by using an assembly line detection method, which uses a conveyor table to send the transformers one by one to the detection station and then take them out after the detection is completed. However, this method is prone to problems. The detection efficiency of a single branch line is low. Although simultaneous detection of multiple branches can improve efficiency, it is also easy to cause confusion. It is difficult to classify qualified and defective transformers, which is relatively inconvenient. Summary of the Invention

[0025] When the second motor is in the forward direction, the second electric push rod drives the telescopic plate to extend, and the slider of the connecting frame slides along the third slide rail and enters the interior of the feeding platform from the guide slide rail and the inlet and outlet. When the clamping assembly and the transformer body on the feeding platform reach this position, the extended end of the third electric push rod is extended and inserted into the insertion hole of the slide rod. Then, the second motor is reversed and the telescopic plate drives the slider to move along the guide slide rail and the third slide rail to the initial position. At this time, due to the insertion of the third electric push rod and the slide rod, the clamping assembly and the transformer body pass through the inlet and outlet and enter the turntable together.

After the two sets of mutual inductors are swapped, they can be sent to different delivery platforms.

[0027] 3. The present invention has two ways of sending out the qualified transformer bodies. One is that the turntable does not rotate and the positions of the two groups of transformer bodies are not swapped, and they are sent back to the original feeding table surface along the same path. The other is that after two testing methods are performed, the direction of the transformer body is opposite to the direction of the transformer on the original feeding table, so it is sent to another group of feeding tables through the turntable to keep the direction of the transformer bodies on each group of feeding tables the same.

[0028] 4. The present invention rotates the bidirectional screw, and the two clamping frames slide along the movable groove and are clamped and fixed on both sides of the bottom of the transformer body. The base is connected to the inside of the first slide rail through a sliding bar. Therefore, it can move with the belt on the surface of the feeding table to continuously transport and detect the transformer. Through the cooperation of the first slide rail, the second slide rail, the third slide rail, the guide slide rail and the guide slide rail, the transformer body and the clamping assembly can be conveniently moved to any table surface, including the process of feeding in, sending out or testing, thereby improving the overall efficiency and avoiding confusion.

[0029] 5. Compared with the prior art, the present invention has two groups of feeding platforms and two groups of sending-out platforms corresponding to the two sides of the testing platform. The transformers on the feeding platforms on both sides can be pulled onto the turntable together with the clamping components through the steering assembly. The detection device on the top frame can be for the same type of detection or for detection of different items. The transformers fed in by two different feeding platforms are detected simultaneously and can be sent out through different sending-out platforms. The direction of the transformer bodies on each group of feeding platforms is kept the same during sending. The transformer bodies with problems are sent out by the sending-out platform, which is convenient for screening and distinguishing qualified and unqualified transformer bodies, while improving the detection efficiency.

[0054] Preferably, but not restrictively, the guide assembly includes: a second motor 56, a rotating column 55, a telescopic plate 57, a shaft 511 and a connecting frame 510. The second motor 56 is fixed at the center of the top of the turntable 52, and the rotating column 55 is fixed to the output end of the second motor 56. The two sides of the rotating column 55 are rotatably connected to the telescopic plate 57 through the rotating shaft, and the extended end of the telescopic plate 57 is rotatably installed with the shaft 511.

The two clamping frames 62 are each provided with a sliding rod 512 on one side where they are close to each other, and the sliding rod on one side is fixed to the second motor 56. 512 is fixedly connected to the clamping frame 62 on one side, and the clamping frame 62 on the other side of the clamping assembly 6 is slidably sleeved on the slide rod 512.

A second electric push rod 58 is fixed to the top of the storage end of the telescopic plate 57, and the extended end of the second electric push rod 58 is fixedly connected to the extended end of the telescopic plate 57 for controlling the extension and retraction of the telescopic plate 57.

[0055] Preferably, but not limitatively, a slider 59 is fixed to the bottom of the connecting frame 510 , and the slider 59 can slide along the inside of the third slide rail 53 .

[0056] Preferably, but not limitatively, the bottoms of the detection platform 13, the feeding platform 2 and the feeding platform 3 are all fixed by support columns, and the surfaces of the detection platform 13, the feeding platform 2 and the feeding platform 3 are flush.

[0057] When using the device, the transformer body 4 is clamped and installed inside the clamping assembly 6, and the transformer body 4 is intermittently arranged through the feeding table 2. The two groups of transformer bodies 4 and the clamping assembly 6 on the feeding table 2 are pulled together onto the steering assembly 5 through the guiding assembly and enter the detection area. One or two tests can be carried out at the same time. After the test is completed, the steering assembly 5 and the guiding assembly cooperate to distinguish and send out qualified and unqualified high-voltage transformers according to the test results, so as to avoid confusion in screening and improve the overall detection efficiency.

[0058] In this section, the transformer body 4 on the feeding platform 2 is pulled onto the turntable 52 by the guide assembly. The specific principle is that the initial position of the slider 59 is located on the third slide rail 53, the second motor 56 drives the rotating column 55 to rotate forward, and at the same time the second electric push rod 58 drives the telescopic plate 57 to extend, and the slider 59 of the connecting frame 510 slides along the third slide rail 53, passes through the guide slide rail 14 and the entrance 21, and enters the first slide rail 22 of the feeding platform 2;

[0059] When the clamping assembly 6 and the transformer body 4 on the feeding platform 2 reach this position, the extended end of the third electric push rod 513 extends out and is inserted into the socket of the slide bar 512. Then, through the reversal of the second motor 56, the telescopic plate 57 drives the slider 59 to move along the guide rail 14 and the third slide rail 53 to the initial position. At this time, due to the insertion of the third electric push rod 513 and the slide bar 512, the clamping assembly 6 and the transformer body 4 are fixed together, and the clamping assembly 6 and the transformer body 4 pass through the inlet and outlet 21 and enter the turntable 52. In this process, the slide bar 66 of the clamping assembly 6 slides along the first slide rail 22, the guide rail 14 and the third slide rail 53 respectively until the plug-in plate 65 is inserted into the plug-in frame 54. Then, the first electric push rod 11 drives the detection contact end 12 to contact the detection end of the transformer body 4, so that the detection end of the transformer body 4 corresponds to the detection contact end 12.

[0060] The detection contact end 12 on the top frame 1 can be used to detect one type, such as the error, size, etc. of the mutual inductor. Preferably, two different types of detection can also be performed, and different detection contact ends 12 can be selected. After completing one detection, the turntable 52 is driven by the first motor 51 to rotate 180 degrees, and all objects on the turntable 52 rotate synchronously, swapping the positions of the two mutual inductor bodies 4, and continuing the detection. After the two sets of mutual inductors are swapped, they can be sent to different feeding tables 2 through the guide assembly. In simple terms, because the two sets of feeding tables are initially 2, in order to avoid affecting subsequent work, there are two ways to send out the qualified transformer bodies 4. One is that the turntable 52 does not rotate and the positions of the two groups of transformer bodies 4 are not exchanged, and they are sent back to the original surface of the feeding platform 2 according to the path they came from. The other is that after the two detection methods are performed, the direction of the transformer bodies 4 is opposite to that of the transformer bodies 4 originally fed into the platform 2, so they are sent to another group of feeding platforms 2 through the turntable 52, and the directions of the transformer bodies 4 on each group of feeding platforms 2 are kept the same.

[0061] When an unqualified transformer body 4 is detected, the first motor 51 drives the turntable 52 to rotate ninety degrees, so that the second slide rail 31 is aligned with the guide slide rail and the third slide rail 53, and the clamping assembly 6 fixed with the unqualified transformer body 4 is pushed into the delivery platform 3 through the guiding assembly, so that the unqualified transformer body 4 is stored separately, realizing the screening and distinction of qualified and unqualified transformer bodies 4, avoiding confusion in screening, and improving the overall detection efficiency.

[0062] Embodiment 2 of the present invention provides a method for detecting a high-voltage transformer, based on the high-voltage transformer detection pipeline provided in embodiment 1, comprising the following steps:

[0063] Step 1: Place the transformer body 4 on the feeding platform 2, and the feeding platform 2 transports the transformer body 4;

[0064] Step 2: The driving component drives the transformer body 4 on the feeding platform 2 to the vicinity of the detection component;

[0065] Step 3: The detection component detects the transformer body 4 and obtains the detection result;

[0066] Step 4: The transformer body 4 that has passed the test is driven by the driving assembly back to the input stage 2, and the transformer body 4 that has failed the test is driven by the driving assembly to the output stage 3.

[0067] Preferably, but not limitatively, in step 1 , the transformer body 4 is clamped and fixed by the two clamping frames 62 of the clamping assembly 6 , and then the clamping assembly 6 is placed on the feeding platform 2 , and the slide bar 66 is inserted into the first slide rail 22 .

[0068] The beneficial effect of the present invention is that, compared with the prior art,

[0069] When the second motor is in the forward direction, the second electric push rod drives the telescopic plate to extend, and the slider of the connecting frame slides along the third slide rail and enters the interior of the feeding platform from the guide slide rail and the inlet and outlet. When the clamping assembly and the transformer body on the feeding platform reach this position, the extended end of the third electric push rod is extended and inserted into the insertion hole of the slide rod. Then, the second motor is reversed and the telescopic plate drives the slider to move along the guide slide rail and the third slide rail to the initial position. At this time, due to the insertion of the third electric push rod and the slide rod, the clamping assembly and the transformer body pass through the inlet and outlet and enter the turntable together. In this process, the slide bar of the clamping assembly slides along the first slide rail, the guide slide rail and the third slide rail respectively until the plug-in plate is inserted into the plug-in frame, and the detection end of the transformer body corresponds to the detection contact end. The detection contact end on the top frame can be used to detect one type.

[0070] 2. The present invention drives the turntable to rotate by the first motor, and all objects on the turntable rotate synchronously. The positions of the two mutual inductor bodies are swapped and the detection is continued. The mutual inductor bodies can also be pushed onto the delivery platform and sent out. After the two sets of mutual inductors are swapped, they can be sent to different delivery platforms.

[0071] 3. The present invention has two ways of sending out the qualified transformer bodies. One is that the turntable does not rotate and the positions of the two groups of transformer bodies are not swapped, and they are sent back to the original feeding table surface along the same path. The other is that after two testing methods are performed, the direction of the transformer body is opposite to the direction of the transformer on the original feeding table, so it is sent to another group of feeding tables through the turntable to keep the direction of the transformer bodies on each group of feeding tables the same.

[0072] 4. The present invention rotates the bidirectional screw, and the two clamping frames slide along the movable groove and are clamped and fixed on both sides of the bottom of the transformer body. The base is connected to the inside of the first slide rail through a sliding bar. Therefore, it can move with the belt on the surface of the feeding table to continuously transport and detect the transformer. Through the cooperation of the first slide rail, the second slide rail, the third slide rail, the guide slide rail and the guide slide rail, the transformer body and the clamping assembly can be conveniently moved to any table surface, including the process of feeding in, sending out or testing, thereby improving the overall efficiency and avoiding confusion.

[0073] 5. Compared with the prior art, the present invention has two groups of feeding platforms and two groups of sending-out platforms corresponding to the two sides of the testing platform. The transformers on the feeding platforms on both sides can be pulled onto the turntable together with the clamping components through the steering assembly. The detection device on the top frame can be for the same type of detection or for detection of different items. The transformers fed in by two different feeding platforms are detected simultaneously and can be sent out through different sending-out platforms. The direction of the transformer bodies on each group of feeding platforms is kept the same during sending. The transformer bodies with problems are sent out by the sending-out platform, which is convenient for screening and distinguishing qualified and unqualified transformer bodies, while improving the detection efficiency.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of protection of the claims of the present invention.
