Description

Technical Field

[0001] The present invention relates to the field of pantograph-catenary arcing detection, and in particular, to a pantograph-catenary arcing simulation device and a control method thereof. Background Art

[0002] An electrified railway train obtains electric energy through the sliding contact between a pantograph and a catenary. When the contact between the pantograph and the catenary is poor or even disconnected, an arcing phenomenon will occur and a large amount of heat will be generated instantaneously, resulting in ablation of the catenary or the pantograph, thereby affecting the safe and stable operation of the train. In order to timely detect the arcing phenomenon in the pantograph-catenary contact and eliminate potential pantograph-catenary contact defects, it is necessary to detect the pantograph-catenary arcing. Nowadays, great attention is paid to the detection of the pantograph-catenary arcing phenomenon. In the European standard "Railway applications - Current collection systems - Requirements and verification of measurements of dynamic interaction between pantographs and overhead lines" (EN 50317-2012), it is clearly stipulated that parameters such as the number of arcing times, arcing duration, and arcing rate are used as parameters for evaluating the operation reliability and operation quality of the current collection system of electrified railways. At present, the above parameters are also used as the dynamic detection and evaluation standards for catenaries in the operation and maintenance of high-speed and normal-speed railways. At present, the existing pantograph-catenary arcing detection devices, whether based on the principles of double-pantograph contact voltage difference, image processing, optical detection, etc., all have problems such as insufficient recognition rate, poor real-time performance, and high false alarm rate to varying degrees, and cannot fully meet the needs of pantograph-catenary arcing detection.

[0003] The improvement of the accuracy and reliability of the pantograph-catenary arcing detection device depends on the understanding of the physical characteristics such as spectral density, power, and duration during the arcing process. However, the arcing phenomenon caused by the poor contact between the pantograph and the catenary during the train operation is relatively random, and it is difficult to repeatedly generate a large number of pantograph-catenary arcs with controllable conditions under the operating state.

[0004] Therefore, there is an urgent need for a pantograph-catenary arcing simulation device that can reproduce the pantograph-catenary arcing in the actual operation process as much as possible through experimental means under laboratory conditions, simulate the pantograph-catenary arcing process, and improve the accuracy of pantograph-catenary arcing detection.

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments herein will be clearly and completely described in conjunction with the accompanying drawings in the embodiments herein. Obviously, the described embodiments are only a part of the embodiments herein, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments herein without making creative efforts shall fall within the scope of protection herein.

[0046] The improvement of the accuracy and reliability of the existing pantograph-catenary arcing detection device depends on the understanding of physical characteristics such as spectral density, power, and duration during the arcing process. However, the phenomenon of arcing caused by the poor contact between the pantograph and the catenary during the train operation is relatively random, and it is difficult to repeatedly generate a large number of pantograph-catenary arcs with controllable conditions under the operating state.

[0047] To solve the above problems, the embodiments of this article provide a pantograph-catenary arcing simulation device. It should be noted that the terms "first", "second", etc. in the specification, claims, and the above-mentioned drawings of this article are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of this article described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product, or equipment that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or equipment.

[0048] Referring to Figure 1 , a pantograph-catenary arcing simulation device includes: a voltage regulation module 1, an arcing gap generation module 2, and a load simulation module 3; the voltage regulation module 1 is connected to the arcing gap generation module 2, and the arcing gap generation module 2 is connected to the load simulation module 3.

[0049] Among them, the voltage regulation module 1 is used to provide voltage for the arcing gap generation module 2. The voltage value provided by the voltage regulation module 1 in this article can be adjusted according to requirements. By adjusting the turns ratio of the adjustable transformer and the wiring method of the step-up transformer, an output voltage in the range of 0 kV to 27.5 kV effective value can be generated from an input voltage with an effective value of 220 V. Specifically, the voltage regulation module 1 includes an adjustable transformer and a step-up transformer. The secondary side of the adjustable transformer is connected to the primary side of the step-up transformer. One terminal of the secondary side of the step-up transformer is grounded, and the other terminal is connected to the arcing gap generation module 2. The effective value of the AC input voltage on the primary side of the adjustable transformer is 220 V, and the adjustment range of the turns ratio of the secondary side to the primary side is 0 to 1. The turns ratio of the secondary side to the primary side of the step-up transformer is 125:1. When the input voltage on the primary side, that is, the output voltage effective value of the adjustable transformer, rises from 0 V to 220 V, the output voltage effective value of the secondary side can rise from 0 kV to 27.5 kV.

[0050] The load simulation module 3 includes an adjustable resistor, an adjustable reactor, and an adjustable capacitor that are connected to each other. In addition, other impedance regulators can also be included. The connection topology of the adjustable resistor, the adjustable reactor, and the adjustable capacitor is not limited. For example, the adjustable resistor, the adjustable reactor, and the adjustable capacitor can be connected in parallel with each other, can be connected in series with each other, or any two of them can be connected in parallel and then connected in series with the third one. By changing the device parameters of the adjustable resistor, the adjustable reactor, or the adjustable capacitor and their connection methods with each other, loads of different sizes and impedance angles can be simulated.

[0051] Referring to Figure 1 andFigure 2 The arc ignition gap generation module 2 includes a first insulator 12 and a catenary simulation component 16, and the first insulator 12 is connected to the catenary simulation component 16. Specifically, the first insulator 12 and the catenary simulation component 16 are connected by a tension plate 13, and the catenary simulation component 16 is connected to the tension plate 13 through an adjusting nut 15. The catenary simulation component 16 can be replaced after loosening the adjusting nut 15. It should be noted that the catenary simulation component 16 is composed of catenary simulation materials and is used to simulate the catenary during the train running process. The catenary simulation component 16 is connected to the ungrounded terminal of the secondary side of the step-up transformer through the adjusting nut 15, and a top plate 11 is fixedly connected to one end of the first insulator 12 away from the catenary simulation component 16.

[0052] Referring to Figure 1 and Figure 3 The arc ignition gap generation module 2 further includes a second insulator 18 and a pantograph carbon slide simulation component 17. The second insulator 18 is connected to the pantograph carbon slide simulation component 17, and the pantograph carbon slide simulation component 17 is connected to the load simulation module 3. The pantograph carbon slide simulation component 17 is connected to the second insulator 18 through bolts, and the pantograph carbon slide simulation component 17 can be replaced after loosening the bolts. It should be noted that the pantograph carbon slide simulation component 17 is composed of pantograph carbon slide simulation materials and is used to simulate the pantograph during the train running process.

[0053] Combined with Figures 4 to 6 The arc ignition gap generation module 2 further includes a control component and a double-acting cylinder 36. The piston rod of the double-acting cylinder 36 is connected to the second insulator 18, and the control component is connected to the double-acting cylinder 36 and is used to control the reciprocating movement of the piston rod, thereby driving the pantograph carbon slide simulation component 17 to approach or move away from the catenary simulation component 16, simulating the approach or departure of the pantograph from the catenary during the train running process.

[0054] The piston rod of the double-acting cylinder 36 can perform two actions of extending and retracting. The double-acting cylinder 36 is a double-acting air cylinder, a double-acting hydraulic cylinder, a double-acting electric cylinder, or a double-acting electromagnetic cylinder. Taking the double-acting air cylinder as an example, air inlets are provided at both ends of the double-acting air cylinder, and the piston rod of the double-acting air cylinder can be extended or retracted by supplying air to the air inlets at both ends respectively; taking the double-acting hydraulic cylinder as an example, hydraulic oil can be introduced into both ends of the double-acting hydraulic cylinder, thereby realizing the extension or retraction of the piston rod of the double-acting hydraulic cylinder.

[0055] In the embodiments of the present invention, the piston rod is connected to the second insulator 18 through a guide rod 20. One end of the guide rod 20 is coaxially connected to the piston rod of the double-acting cylinder 36, and the other end is connected to the second insulator 18. It should be noted that a support plate 19 is provided on the side of the second insulator 18 close to the guide rod 20, and the guide rod 20 is connected to the second insulator 18 through the support plate 19. Specifically, one end of the guide rod 20 is detachably connected to the support plate 19 by bolts, and the other end of the guide rod 20 is detachably connected to the piston rod of the double-acting cylinder 36. The detachable connection method can be that the guide rod 20 is threadedly connected to the piston rod, or the guide rod 20 is connected to the piston rod by bolts. The present invention does not limit the specific detachable connection method.

[0056] In the embodiments of the present invention, the arc generation module 2 further includes a limiting component, which is connected to the piston rod of the double-acting cylinder 36 and is used to limit the pulling distance between the carbon slide simulation member 17 and the contact wire simulation member 16.

[0057] Specifically, the limiting component includes a sleeve 29, an adjusting member, and a limiting plate 30. The sleeve 29 is sleeved on the guide rod 20. Since the guide rod 20 is connected to the piston rod, the sleeve 29 is also sleeved on the piston rod. The adjusting member is connected to the sleeve 29, and the limiting plate 30 is connected to the cylinder block of the double-acting cylinder 36. The adjusting member is used to adjust the first distance between the sleeve 29 and the limiting plate 30, thereby adjusting the pulling distance between the carbon slide simulation member 17 and the contact wire simulation member 16. It can be understood that since the limiting plate 30 is connected to the cylinder block of the double-acting cylinder 36, when the adjusting member adjusts the first distance, the limiting plate 30 is relatively stationary, the sleeve 29 moves relative to the limiting plate 30, and the first distance between the sleeve 29 and the limiting plate 30 is the pulling distance between the carbon slide simulation member 17 and the contact wire simulation member 16.

[0058] Refer to Figure 4 and Figure 5 As shown in [relevant figure numbers], the adjusting member includes a stabilizing rod 27, a stabilizing plate 37, a rotating plate 38, a first gear 39, a second gear 40, a third gear 41, and a motor 25. There are two stabilizing rods 27, and both stabilizing rods 27 are arranged parallel to the guide rod 20 and are detachably connected. The stabilizing plate 37 is sleeved on the two stabilizing rods 27, and the stabilizing plate 37 slides axially along the two stabilizing rods 27. Specifically, both stabilizing rods 27 are connected to the guide rod 20 through guide plates 21. The guide plates 21 are detachably connected to the guide rod 20 by locking nuts 23. One end of the guide plate 21 close to the threaded rod is provided with a guide seat 22, and the threaded rod is threadedly connected to the guide seat 22, or any other feasible way.

[0059] The guide rod 20 is a threaded rod, the first gear 39 is sleeved on the guide rod 20 and the inner ring of the first gear 39 is threadedly connected to the guide rod 20, the rotating plate 38 is sleeved on the guide rod 20, the rotating plate 38 is fixedly connected to the sleeve 29, and the first gear 39 is fixedly connected to the rotating plate 38.

[0060] The outer gear ring of the first gear 39 is meshed with the second gear 40, the outer gear ring of the second gear 40 is meshed with the third gear 41, the inner ring of the third gear 41 is fixedly connected to the motor shaft of the motor 25, and the housing of the motor 25 is fixedly connected to the stabilizing plate 37; a groove is provided at one end of the stabilizing plate 37 close to the rotating plate 38, and the rotating plate 38 is in a round shape, and the edge of the rotating plate 38 is located in the groove; specifically, a ball is provided in the groove, and when the rotating plate 38 rotates in the groove, the ball can reduce the friction generated during the rotation process.

[0061] When the motor shaft of the motor 25 rotates, it drives the third gear 41 to rotate, the third gear 41 drives the second gear 40 to rotate, the second gear 40 drives the first gear 39 to rotate, the first gear 39 rotates and moves along the axial direction of the guide rod 20, drives the rotating plate 38 to rotate and move along the axial direction of the guide rod 20, drives the sleeve 29 to rotate and move along the axial direction of the guide rod 20 to adjust the first distance, and drives the stabilizing plate 37 to move along the axial direction of the stabilizing rod 27.

[0062] During the adjustment process, it is necessary to first clarify that the size of the first distance between the sleeve 29 and the limit plate 30 determines the pulling distance between the carbon skateboard simulation part 17 and the contact line simulation part 16. If you want to change the pulling distance, you need to adjust the first distance. During the adjustment, the piston rod of the double-acting cylinder 36 is stationary, so the guide rod 20 is stationary, and the third gear 41 is driven to rotate by the rotation of the motor 25, so that the second gear 40 meshing with the third gear 41 is rotated, and then the first gear 39 is driven to rotate. The inner ring of the first gear 39 is provided with a thread that matches the guide rod 20. Since the guide rod 20 is stationary, the first gear 39 will move along the axial direction of the guide rod 20 while rotating. When the first gear 39 moves, it will drive the rotating plate 38 fixedly connected to it to move along the axial direction of the guide rod 20. The movement of the rotating plate 38 will drive the sleeve 29 fixedly connected to it to move along the axial direction of the guide rod 20. The first distance between the sleeve 29 and the limit plate 30 will change accordingly during the movement.

[0063] When conducting the arc burning simulation experiment of the bow net, in the initial state, the carbon slide simulation part 17 is in contact with the contact line simulation part 16, and the interval between the sleeve 29 and the limit plate 30 is the first distance; during the experiment, the piston rod of the double-acting cylinder 36 is recovered, driving the carbon slide simulation part 17 to move away from the contact line simulation part 16. Due to the recovery of the piston rod, the guide rod 20 is driven to move synchronously. Since the guide rod 20 is threadedly connected with the first gear 39, the first gear 39 is driven to move when the guide rod 20 moves. The first gear 39 is fixedly connected to the rotating plate 38, driving the rotating plate 38 to move. The edge of the rotating plate 38 is located in the groove of the stabilizing plate 37, so the stabilizing plate 37 moves along the axial direction of the stabilizing rod 27, thereby driving the motor 25 to move. In this process, the sleeve 29 is fixedly connected to the rotating plate 38, and the sleeve 29 moves in the direction close to the limit plate 30 until the sleeve 29 contacts the limit plate 30, and the carbon slide simulation part 17 can no longer move away from the contact line simulation part 16.

[0064] Therefore, combining the above adjustment process with the bow-net arcing simulation experiment, when it is necessary to adjust the pulling distance between the carbon slide plate simulation component 17 and the contact line simulation component 16, because the first distance is equal to the pulling distance, it is necessary to adjust the first distance between the sleeve 29 and the limit plate 30.

[0065] Combination Figure 6 In the embodiment of this article, the motor 25 is connected to an adjusting block 26, and the stabilizing rod 27 is connected to an adjusting switch 28. The connection between the adjusting switch 28 and the stabilizing rod 27 can be a detachable connection or a fixed connection, and the adjusting switch 28 is electrically connected to the control component.

[0066] The control member controls the rotation of the motor shaft of the motor 25 to adjust the second distance between the adjusting bump 26 and the adjusting switch 28. The first distance is equal to the second distance. When the adjusting bump 26 contacts the adjusting switch 28, the control member controls the motor shaft of the motor 25 to stop rotating. When the motor 25 rotates, it will drive the sleeve 29 to move. When adjusting the first distance (i.e., the pulling distance) between the sleeve 29 and the limiting plate 30, it is usually necessary to first make the sleeve 29 contact the limiting plate 30, and the first distance is 0. Then, adjust the first distance between the sleeve 29 and the limiting plate 30 according to the required distance. The state where the first distance is 0 is the zero position state of the arcing gap. In this state, the second distance is 0. Since it is necessary to first make the first distance 0 when adjusting the first distance, at this time, the control member needs to control the rotation of the motor shaft of the motor 25 to make the sleeve 29 approach the limiting plate 30. Since the adjusting switch 28 is connected to the stabilizing rod 27 and the two are relatively stationary, the motor 25 moves closer to the adjusting switch 28. Since the adjusting bump 26 is connected to the motor 25, the adjusting bump 26 approaches the adjusting switch 28 under the drive of the motor 25. Since the first distance is equal to the second distance, when the adjusting bump 26 contacts the adjusting switch 28, at this time, the second distance is 0. Similarly, the first distance is also 0. Since the adjusting bump 26 contacts the adjusting switch 28, the controller 33 will control the motor 25 to stop rotating at this time, indicating that the arcing gap is in the zero position state at this time.

[0067] A protection bump 31 is connected to the limiting plate 30, and a protection switch 32 is connected to the stabilizing rod 27. The connection manner between the protection switch 32 and the stabilizing rod 27 can be a detachable connection or a fixed connection. The protection switch 32 is electrically connected to the control member; when the carbon slider simulation member 17 is pulled away from the contact wire simulation member 16, the protection bump 31 is separated from the protection switch 32 to prevent the rotation of the motor shaft of the motor 25.

[0068] When performing the pantograph-catenary arcing simulation experiment, the carbon slider simulation member 17 moves away from the contact wire simulation member 16. At this time, the protection switch 32 moves away from the protection bump 31. When the protection switch 32 and the protection bump 31 are not in contact, the control member controls the motor shaft of the motor 25 to remain in a non-rotating state. The purpose is that the rotation of the motor shaft of the motor 25 will drive the sleeve 29 to move closer to or away from the limiting plate 30 to change the first distance, and then change the pulling distance between the carbon slider simulation member 17 and the contact wire simulation member 16. When performing the pantograph-catenary arcing simulation experiment, the first distance cannot be changed randomly. Therefore, it is necessary to prevent the rotation of the motor shaft of the motor 25 to ensure the accuracy of the experiment.

[0069] The control component includes a controller 33 and a solenoid valve 34, wherein the solenoid valve 34 is electrically connected to the controller 33 and connected to two inlets of the double-acting cylinder 36. Since the double-acting cylinder 36 can be a double-acting air cylinder or a double-acting hydraulic cylinder, the solenoid valve 34 is also connected to an air compressor or a hydraulic pump to provide gas or liquid to the double-acting air cylinder or the double-acting hydraulic cylinder. Under the control of the controller 33, the solenoid valve 34 ventilates or passes liquid to any one of the two inlets of the double-acting cylinder 36, thereby controlling the piston rod of the double-acting cylinder 36 to extend or retract. Specifically, the motor 25, the regulating switch 28 and the protection switch 32 are all electrically connected to the controller 33, and perform corresponding actions under the control of the controller 33.

[0070] Reference Figure 7 Based on the above-mentioned bow-catenary arcing simulation device, this article also provides a control method for controlling the above-mentioned bow-catenary arcing simulation device, including:

[0071] S101: After the bow-catenary arcing simulation device is powered on, the piston rod of the double-acting cylinder is controlled to extend, and the contact line simulation component and the carbon slide plate simulation component are in contact state;

[0072] S102: Control the piston rod to retract, so that the carbon slide plate simulation part is separated from the contact line simulation part to generate an arc.

[0073] When conducting the bow-net arcing simulation experiment, in the initial state, the piston rod of the double-acting cylinder is extended, and the contact wire simulation part is in contact with the carbon slide plate simulation part. During the experiment, the piston rod is retracted, and the carbon slide plate simulation part is separated from the contact wire simulation part to generate an arc.

[0074] Reference Figure 8 , wherein the control method further comprises:

[0075] S201: controlling the motor to rotate until the adjustment block contacts the adjustment switch, and then controlling the motor to stop rotating;

[0076] S202: Control the motor to rotate in the reverse direction, and adjust the distance between the adjusting block and the adjusting switch, thereby adjusting the distance between the carbon slide simulation component and the contact line simulation component.

[0077] When adjusting the pulling distance between the carbon slide simulation component and the contact line simulation component, the motor is controlled to rotate so that the adjustment block contacts the adjustment switch and the arcing gap is in the zero position. Since the distance between the adjustment block and the adjustment switch is equal to the pulling distance between the carbon slide simulation component and the contact line simulation component, the motor rotates in the opposite direction to adjust the pulling distance.
