Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment detection, and in particular to an electrical primary equipment comprehensive test device and method based on power load control. BACKGROUND

[0002] Power load control (also known as load management) is a systematic measure to regulate and manage the power load of a power system through technology and other means to achieve safe, economic and efficient operation of the power grid. Its core goal is to flatten the peak and fill the valley, balance the load curve, and thus improve the economy, safety and energy utilization efficiency of power grid operation.

[0003] For example, the prior art patent CN112462094B, named a special test clamp for main transformer bushing loop resistance and its use method, includes a pair of parallel arranged movable and fixed jaws, the fixed jaw is fixedly connected with a fixed handle at the lower end, the movable jaw is fixedly connected with a connecting plate at the lower end through a horizontal adjusting mechanism, the connecting plate is hingedly connected with the left side of the fixed handle at the lower right end and can be self-positioned, the connecting plate is hingedly connected with a movable handle at the lower left end and can be self-positioned, the movable handle is hingedly connected to the end of a push rod at the right side, the other end of the push rod is hingedly connected to the fixed handle and can move up and down along the fixed handle, the other end of the push rod is abutted with a screw rod at the lower side, the screw rod is screw-connected with the fixed handle at the lower end, and the connecting plate is obliquely connected to the fixed handle at the lower middle through a spring.

[0004] Because the test contact and the winding terminal are in instantaneous contact, an oxide layer is generated. The reason for generating the oxide layer is that the metal surface looks smooth, but is actually composed of uneven microstructure. When the test frame contacts the terminal, only part of the convex area is truly contacted, and the effective contact area is much smaller than the apparent area. This insufficient contact can cause the local current density to increase, and the current is concentrated in a few contact points, which can cause local high temperature and accelerate the oxidation reaction. The metal exposed to the air (such as copper and aluminum) will spontaneously react with oxygen to form an oxide film (such as Cu2O and Al2O3), and even short-time contact cannot be avoided.

[0005] Therefore, when testing the resistance of power grid equipment such as transformers, it is usually necessary to clean the oxide layer by friction to ensure the conductivity efficiency and then ensure the accuracy of the test results. However, the existing technical equipment does not have this function when connected with the terminal, and the oxide film formed will significantly reduce the conductivity efficiency, resulting in inaccurate test results.

It should be noted that the first telescopic rod 6, the second telescopic rod 9 and the third telescopic rod 10 can be electric telescopic rods or hydraulic telescopic rods.

[0050] In the above scheme, the third telescopic rod 10 can control the support seat 7, the lifting seat 8 and the movable arm 5 to approach or move away from the transformer 3, thereby facilitating the subsequent detection of the resistance value of the transformer 3.

[0051] As shown in the figure, Figure 6 The inside of the movable arm 5 is provided with a gas generating cavity 11, the gas generating cavity 11 is located in the middle part of the movable arm 5, the inside of the gas generating cavity 11 is provided with a gas generator 12, the gas generator 12 can be made of rubber, when the gas generator 12 slides in the gas generating cavity 11, the gas in the gas generating cavity 11 can be extruded in the pushing direction of the gas generator 12, one end of the gas generating cavity 11 is also provided with a pressure relief hole 13, one end of the gas generator 12 is connected with a fourth telescopic rod 14, the fourth telescopic rod 14 is installed in the inside of the movable arm 5, and the fourth telescopic rod 14 is used to drive the gas generator 12 to reciprocate in the inside of the gas generating cavity 11.

[0052] As shown in the figure, Figure 7 , Figure 8As shown, the lower end of the movable arm 5 away from the lifting seat 8 is provided with two clamping plates 15, which can move closer to or away from each other, and when they move closer to each other, they can clamp the terminal 4 to prevent the terminal 4 from shaking during detection. The outer side of the two clamping plates 15 is provided with a fixed sleeve 16, the top of which is fixedly connected with the bottom of the movable arm 5, and the end of the clamping plate 15 close to the fixed sleeve 16 is connected with a limiting sleeve 17, which is slidingly connected with the outside of the fixed sleeve 16. The inside of the limiting sleeve 17 is provided with a limiting block 19, which is slidingly connected with the inside of the fixed sleeve 16, so that the clamping plate 15, the limiting block 19 and the limiting sleeve 17 can slide along the inside of the fixed sleeve 16. A first spring 18 is also connected to one end of the limiting block 19, and the other end of the first spring 18 is fixed to the inner wall of the fixed sleeve 16. The lower side of the side of the two clamping plates 15 close to each other has an inclined surface, which can adapt to the end of the terminal 4 when the two clamping plates 15 move from above the terminal 4 to below the terminal 4 under the action of the movable arm 5. The first spring 18 can be self-adapted to contract according to the thickness of the terminal 4, and at the same time, the two clamping plates 15 can clamp the terminal 4 through the elastic force of the first spring 18.

[0053] As shown in the figure, Figure 9 The lower side of the test bench 1 is also provided with a grounding device, which includes a grounding column 21, and the outside of the grounding column 21 is provided with a sliding sleeve 20, which is fixedly connected to the bottom of the test bench 1. The end of the grounding column 21 close to the test bench 1 is connected with a movable column 22, and the conductive core of the grounding column 21 passes through the middle part of the movable column 22. A second spring 23 is connected between one end of the movable column 22 and the middle part of the sliding sleeve 20. The default state of the second spring 23 can make the grounding column 21 in the state of extending out of the test bench 1. When the driving device 2 drives the test bench 1 to approach the transformer 3, the end of the grounding column 21 contacts the grounding part of the shell of the transformer 3 under the elastic action of the second spring 23. The grounding column 21 is electrically connected with the detection equipment inside the test bench 1 through the conductive core.

[0054] As shown in the figure, Figure 10 The inside of the movable arm 5 is provided with an air outlet hole 24, one end of which is in communication with one end of the gas generating cavity 11, and the other end of the air outlet hole 24 penetrates to the lower side of the movable arm 5 and is connected with an extension pipe 25. The middle part of the clamping plate 15 close to the extension pipe 25 is provided with a gas jet hole 26, the two ends of which are inclined and penetrate the thickness direction of the clamping plate 15. The end of the gas jet hole 26 close to the extension pipe 25 is connected with a fixed pipe 27, which is connected with the extension pipe 25 in a sleeved manner, and the contact surface of the two is in close contact, forming a seal, which can be sealed by a sealing ring.

[0055] In the above scheme, when the gas generator 12 is driven to slide by the fourth telescopic rod 14, the right side gas of the gas generating cavity 11 can be extruded, so that the gas enters the jet hole 26 from the gas outlet hole 24, the extension pipe 25 and the fixed pipe 27 in turn, and then passes through the narrowed part in the middle of the jet hole 26. Based on the continuity equation and Bernoulli effect in fluid mechanics, the speed of the ejected gas increases, thereby removing the dust and dirt on the contact part at the top of the terminal 4.

[0056] As shown in Figure 9 , Figure 10 , the rotating hole 28 is formed in the movable arm 5, the rotating sleeve 32 is arranged in the rotating hole 28, the conductive column 33 is arranged in the rotating sleeve 32, the conductive block 29 is arranged at the bottom of the rotating sleeve 32, the conductive block 29 can rotate synchronously with the rotating sleeve 32, the top of the conductive block 29 is electrically connected with the detection equipment in the test table 1 through the wire 31, and the above scheme forms a loop with the conductive block 29, the conductive column 33, the wire 31, the detection equipment, the grounding column 21, the elements in the transformer 3 and the terminal 4. In order to ensure stable connection, the bottom end of the wire 31 is connected with the cover 36 through the third spring 35, so that the bottom end of the wire 31 is always in contact with the conductive column 33, and poor contact is avoided. The cover 36 covers the top of the movable arm 5, so that the detection equipment can perform resistance detection on the transformer 3.

[0057] As shown in Figure 10 , Figure 11 , the driven bevel gear 30 is fixedly connected to the top of the rotating sleeve 32, the driving bevel gear 34 is arranged on one side of the driven bevel gear 30, the top of the movable arm 5 is provided with a containing groove, the driven bevel gear 30 and the driving bevel gear 34 are contained in the containing groove, the cover 36 is fixedly arranged at the top of the containing groove, the driven bevel gear 30 is in a right-angle meshing state with the driving bevel gear 34, the driving bevel gear 34 is rotatably arranged in the movable arm 5, and the driving bevel gear 34 can rotate under the drive of the driving source.

[0058] In the above scheme, when the driving bevel gear 34 rotates, the driven bevel gear 30 can be driven to rotate synchronously due to the meshing effect, the rotating sleeve 32 and the conductive block 29 rotate synchronously, so that when the conductive block 29 is in contact with the top of the terminal 4, the oxide layer generated by the contact of the two can be removed by rotation, thereby improving the conductivity and increasing the accuracy of the detection result.

[0059] As shown in Figure 11 , in order to ensure the connection reliability of the conductive block 29 and the terminal 4, the specific configuration mode of the conductive block 29 and the conductive column 33 is as follows:

[0060] The conductive block 29 is slidingly installed in the extrusion sleeve 37, the extrusion sleeve 37 is sleeved at the bottom of the rotating sleeve 32, and the two form a limiting structure of mutual buckling Figure 11 As shown, the top of the extrusion sleeve 37 and the outer wall of the rotating sleeve 32 are connected with the fourth spring 38, and the fifth spring 39 is further connected between the conductive block 29 and the inner wall bottom of the extrusion sleeve 37, the top of the conductive block 29 is connected with the conductive sheet 40 through the conductive spring 41, the top of the conductive sheet 40 is in contact with the bottom of the conductive column 33, and the conductive column 33 and the conductive block 29 are connected in series through the conductive sheet 40 and the conductive spring 41;

[0061] In the above scheme, when the rotating sleeve 32 is lowered synchronously with the movable arm 5, and the conductive block 29 is in contact with the top of the terminal 4, the extrusion sleeve 37, the conductive block 29 and the conductive sheet 40 can be further compressed under the action of the fourth spring 38, the fifth spring 39 and the conductive spring 41, so that the descending distance of the movable arm 5 only needs to be specified within a certain range, providing a buffer redundant space, avoiding rigid contact, and causing damage to the terminal 4.

[0062] As shown in Figure 12 , Figure 13 As a way to drive the driving bevel gear 34 to rotate, one end of the driving bevel gear 34 is connected with the driving sleeve 42, the open end of the driving sleeve 42, that is, the end close to the gas generation cavity 11 is provided with the driving column 43, the inner wall of the driving sleeve 42 is provided with the spiral groove 44, one end of the driving column 43 close to the driving sleeve 42 is connected with the driving ball 45, the other end of the driving column 43 is fixed with the gas generator 12, and the driving ball 45 is configured to slide inside the spiral groove 44;

[0063] In the above scheme, when the fourth telescopic rod 14 drives the gas generator 12 to move, the driving column 43 can be driven to move, and the driving ball 45 at the end of the driving column 43 slides inside the driving sleeve 42. Because the gas generator 12 and the gas generation cavity 11 have a limiting structure, the gas generator 12 and the driving column 43 can only move along the axis and cannot rotate, so the driving sleeve 42 can rotate under the push of the driving ball 45 and the spiral groove 44;

[0064] And in actual application, it is divided into the following steps:

[0065] When the movable arm 5 is entirely above the terminal 4, the distance can align the upper part of the terminal 4 with the jet hole 26, and the movable arm 5 can be stationary, and then the gas generator 12 is driven to move by the fourth telescopic rod 14 to press the gas on the right side of the gas generation cavity 11, so that the gas enters the jet hole 26 from the gas outlet hole 24, the extension pipe 25 and the fixed pipe 27 in sequence, and then passes through the narrowed part in the middle of the jet hole 26, and based on the continuity equation and Bernoulli effect in fluid mechanics, the speed of the jet gas is increased, so as to clean the dust and dirt on the contact part at the top of the terminal 4.

[0066] Then the movable arm 5 continues to descend to abut the conductive block 29 against the top of the terminal 4 (and can continue to press down to cause the fourth spring 38, the fifth spring 39 and the conductive spring 41 to be pressed to avoid poor contact), at this time, the gas generator 12 and the driving column 43 move to the left side of the driving sleeve 42, and through the action of the driving ball 45 and the spiral groove 44, the driving sleeve 42 and the driving bevel gear 34 are rotated, so as to drive the conductive block 29 to rotate synchronously, when the conductive block 29 contacts the top of the terminal 4, the oxide layer generated by the contact between the two can be removed by the rotation, so as to improve the conductivity and increase the accuracy of the detection result.

[0067] Embodiment two: The technical scheme of the embodiment is different from that of embodiment one, and the embodiment provides an electrical primary equipment comprehensive test method based on power load control, including the following steps:

[0068] S1, the test bench 1 is driven by the driving device 2 to approach the transformer 3, so that the grounding device contacts the grounding area on the transformer 3;

[0069] S2, the driving device 2 is finely adjusted to align the end of the movable arm 5 with the upper part of the terminal 4;

[0070] S3, when the movable arm 5 is entirely above the terminal 4, the gas generator 12 is driven to move by the fourth telescopic rod 14 to press the gas on the right side of the gas generation cavity 11, so that the gas enters the jet hole 26 from the gas outlet hole 24, the extension pipe 25 and the fixed pipe 27 in sequence, and then passes through the narrowed part in the middle of the jet hole 26, and based on the continuity equation and Bernoulli effect in fluid mechanics, the speed of the jet gas is increased, so as to clean the dust and dirt on the contact part at the top of the terminal 4;

[0071] S4, the movable arm 5 continues to descend, and the conductive block 29 abuts against the top of the terminal 4 (and can continue to be pressed down, so as to cause the fourth spring 38, the fifth spring 39 and the conductive spring 41 to be pressed, and avoid poor contact), at this time, the gas generator 12 and the driving column 43 move to the left side of the driving sleeve 42, through the driving ball 45 and the helical groove 44, the driving sleeve 42 and the driving bevel gear 34 are rotated, so as to drive the conductive block 29 to rotate synchronously, when the conductive block 29 contacts the top of the terminal 4, the oxide layer generated by the contact between the two can be removed through the rotation, so as to improve the conductivity and increase the accuracy of the detection result;

[0072] S5, the detection device inside the test bench 1 starts to work, and the resistance of the transformer 3 is detected through the current and the voltage.
