Description

Technical Field

[0001] The present application belongs to the technical field of detection equipment, and more specifically, to a device for detecting the scaling degree of a voltage-equalizing electrode. Background Art

[0002] The converter valve is the main equipment of the high-voltage direct current transmission system. Since the converter valve will generate a lot of heat due to losses during operation, it is necessary to use the cold water cooling system inside the converter valve to discharge the heat, so that the temperature of the converter valve is normal, thereby avoiding damage to the components of the converter valve due to overheating. The voltage-equalizing electrode is an important component in the cold water system inside the converter valve. It is usually arranged in the confluence water pipe at the inlet and outlet of the cooling water. It is a cylindrical platinum metal part with a smooth tip. The main function of the voltage-equalizing electrode is to connect the adjacent aluminum radiators so that the potential of the radiator is consistent with the potential of the corresponding position of the confluence water pipe, thereby avoiding leakage current in the radiator and preventing the surface of the radiator from electrochemical corrosion, thereby protecting the normal operation of the cold water system inside the converter valve.

[0003] However, in actual operation, scaling often occurs on the surface of the voltage-equalizing electrode, which has a negative impact on its performance and may cause the failure of the converter valve, thereby threatening the safe and stable operation of the entire high-voltage direct current transmission system. Therefore, it is necessary to regularly detect the scaling degree of the voltage-equalizing electrode. The existing technology mainly uses manual sampling to detect the scaling degree of the voltage-equalizing electrode. Manual sampling requires the disassembly of the voltage-equalizing electrode, which is a cumbersome process, time-consuming and labor-intensive, with low detection efficiency and high risks.

[0042] Please also read Figures 1 to 3 Now, a device for detecting the scaling degree of an equalizing electrode provided in an embodiment of the present application is described.

[0043] See also Figure 1 , a device for detecting the scaling degree of a voltage-equalizing electrode comprises: a body component 10, an electrical control unit 20, a human-machine interface 30, an X-ray source 40, an X-ray acquisition unit 50 and a safety protection unit. The body assembly 10 has a detection area 13, and the detection area 13 is used to place the pipe 100 with the voltage-equalizing electrode to be tested installed; the electrical control unit 20 is installed on the body assembly 10; the human-machine interface 30 is installed on the body assembly 10 and is electrically connected to the electrical control unit 20; the X-ray source 40 is installed on the body assembly 10 and is arranged corresponding to the detection area 13, and the X-ray source 40 is electrically connected to the electrical control unit 20 through a signal line, and the X-ray source 40 is used to emit X-rays to the pipe 100 placed in the detection area 13; the X-ray acquisition unit 50 is installed on the body assembly 10 and is arranged relative to the X-ray source 40, and the X-ray acquisition unit 50 is electrically connected to the electrical control unit 20 through a signal line, and the X-ray acquisition unit 50 is used to receive X-rays that pass through the pipe 100 and the voltage-equalizing electrode, and send the collected X-ray signals to the electrical control unit 20. The safety protection unit 80 is installed on the body assembly 10 and wraps the X-ray source 40 and the X-ray acquisition unit 50.

[0044] The electrical control unit 20 is used to receive instructions from the human-machine interface 30 and is also used to control the operation of the X-ray source 40 and the X-ray acquisition unit 50 to achieve the acquisition of X-ray signals.

[0045] The human-machine interface 30 is used to provide data input and reading functions, that is, the human-machine interface 30 is the operation and display center of the voltage-equalizing electrode scaling degree detection device. The operator can set parameters through the human-machine interface 30 and view the collected X-rays to achieve human-machine interaction.

[0046] When the pipeline 100 equipped with the voltage equalizing electrode is placed in the detection area 13, the X-ray source 40 is located on one side of the pipeline 100, and the X-ray acquisition unit 50 is located on the other side of the pipeline 100 relative to the X-ray source 40. The X-ray source 40 can emit X-rays perpendicular to the length direction of the voltage equalizing electrode, and the X-rays can penetrate the pipeline 100 and the voltage equalizing electrode. The X-ray acquisition unit 50 can quickly acquire scaling X-rays of the voltage equalizing electrode by receiving the X-rays that pass through the pipeline 100 and the voltage equalizing electrode, thereby acquiring scaling information of the voltage equalizing electrode.

[0047] The present application provides a device for detecting the degree of scaling of a voltage-equalizing electrode. Compared with the prior art, when the device for detecting the degree of scaling of a voltage-equalizing electrode is used, a pipeline 100 on which the voltage-equalizing electrode to be tested is installed is placed in a detection area 13, and an X-ray source 40 emits X-rays to the pipeline 100 in the detection area 13. The X-rays can penetrate the pipeline 100 and the voltage-equalizing electrode. The X-ray acquisition unit 50 receives the X-rays that pass through the pipeline 100 and the voltage-equalizing electrode and sends them to the electrical control unit 20. The electrical control unit 20 displays the X-ray results through the human-machine interface 30 to obtain the degree of scaling of the voltage-equalizing electrode. Information, in this way, the scaling degree of the voltage-equalizing electrode can be detected without disassembling the voltage-equalizing electrode. The detection speed is fast, the accuracy is high, and it is convenient, which is conducive to saving manpower, and it is not easy to damage the components of the cold water cooling system in the converter valve. At the same time, it can also realize real-time monitoring and early warning of the scaling degree of the voltage-equalizing electrode, providing a strong guarantee for the safe and stable operation of the high-voltage direct current transmission system. In addition, the X-ray source 40 and the X-ray acquisition unit 50 are electrically connected to the electrical control unit 20 through a signal line, so that the signal transmission is stable and fast, and the scaling degree of the voltage-equalizing electrode can be obtained quickly and accurately. By wrapping the X-ray source 40 and the X-ray acquisition unit 50 with the safety protection unit 80, not only can the X-ray source 40 and the X-ray acquisition unit 50 be protected from the influence of the external environment, but also the radiation damage to the operator by X-rays can be effectively prevented, and the safety is high.

[0048] It should be noted that the electrical control unit 20 obtains the X-ray scaling image of the voltage-equalizing electrode through the X-ray acquisition unit 50, and can obtain parameters reflecting the scaling degree such as the scaling length and thickness of the voltage-equalizing electrode.

[0049] In one embodiment of the present application, see Figure 1 The device for detecting the scaling degree of the voltage-equalizing electrode further includes a power supply unit 60 , which is installed on the body assembly 10 and is electrically connected to the electrical control unit 20 for providing electrical energy.

[0050] Specifically, the power supply unit 60 is used to provide power to the electrical control unit 20, the human-machine interface 30, the X-ray source 40, the X-ray acquisition unit 50 and other components. In addition, since the power supply unit 60 is electrically connected to the electrical control unit 20, and the X-ray source 40 and the X-ray acquisition unit 50 are both electrically connected to the electrical control unit 20 through signal lines, the power supply unit 60 can stably supply power to the X-ray source 40 and the X-ray acquisition unit 50 through the electrical control unit 20.

[0051] Optionally, the power supply unit 60 is a rechargeable battery pack.

[0052] For example, the power supply unit 60 has a charging port and a discharging port. The charging port is used to connect to the mains to charge the power supply unit 60, and the discharging port is used to electrically connect to the electrical control unit 20 to discharge the power supply unit 60. In this way, the power supply unit 60 can be cyclically charged and discharged, so that the power supply unit 60 can provide long-term and stable power supply.

[0053] In one embodiment of the present application, see Figure 1 The device for detecting the scaling degree of the voltage-equalizing electrode further includes a warning unit 70 , which is installed on the body assembly 10 and electrically connected to the X-ray source 40 for displaying the working status of the X-ray source 40 .

[0054] The warning unit 70 displays the working status of the X-ray source 40 to remind the operator to pay attention to safety, which is beneficial to improving the safety of the operator.

[0055] Optionally, the warning unit 70 includes an indicator light, and when the X-ray source 40 is working, the indicator light emits light for prompting.

[0056] Optionally, the warning unit 70 includes an electronic sounder, which emits an alarm sound to provide a prompt when the X-ray source 40 is working.

[0057] Optionally, the warning unit 70 includes an indicator light and an electronic sounder. When the X-ray source 40 is working, the indicator light emits light for prompting, and at the same time, the electronic sounder emits an alarm sound for prompting.

[0058] In one embodiment of the present application, see Figure 1 The human-machine interface 30 and the warning unit 70 are installed on the same side of the body assembly 10. By installing the human-machine interface 30 and the warning unit 70 on the same side of the body assembly 10, when the operator operates the human-machine interface 30, it is convenient for the operator to obtain the working status of the X-ray source 40 through the warning unit 70.

[0059] In one embodiment of the present application, see Figure 1 and Figure 2The body assembly 10 includes a first machine platform 11 and a second machine platform 12. The first machine platform 11 and the second machine platform 12 are spaced apart from each other. The second machine platform 12 has a detection area 13. The electrical control unit 20, the human-machine interface 30, the power supply unit 60 and the warning unit 70 are all installed on the first machine platform 11. The X-ray source 40 and the X-ray acquisition unit 50 are installed on the second machine platform 12.

[0060] By spacing the first platform 11 and the second platform 12 , the X-ray source 40 and the X-ray acquisition unit 50 are separated from the electrical control unit 20 and the human-machine interface 30 , which helps to reduce the radiation level to which the operator is exposed when operating the human-machine interface 30 .

[0061] Optionally, the electrical control unit 20 and the power supply unit 60 are both installed inside the first machine 11, and the human-machine interface 30 and the warning unit 70 are installed outside the first machine 11, and the human-machine interface 30 and the warning unit 70 are located on the same side of the first machine 11, and the power supply unit 60 is located on the back of the human-machine interface 30. The layout is reasonable and the structure is compact, which is conducive to reducing the overall volume of the device and is convenient to carry.

[0062] In one embodiment of the present application, see Figure 2 and Figure 3 The safety protection unit 80 is covered on the second machine platform 12 to cover the X-ray source 40 and the X-ray collection unit 50 .

[0063] The safety protection unit 80 is a shell protection structure that is adapted to the shape of the second machine platform 12 and can isolate X-rays.

[0064] In one embodiment of the present application, see Figure 1 and Figure 2 The X-ray source 40 is located above the detection area 13 and can slide up and down, and the X-ray collection unit 50 is located below the detection area 13.

[0065] By locating the X-ray source 40 above the detection area 13 and enabling it to slide up and down, the X-ray source 40 can be slid up and down to move away from or close to the pipeline 100 on the detection area 13 where the voltage-equalizing electrode to be tested is installed, so as to adjust the distance between the X-ray source 40 and the pipeline 100, thereby adapting to pipelines 100 of different sizes equipped with voltage-equalizing electrodes to be tested, so that the voltage-equalizing electrode scaling degree detection device has a wide range of applications, which is beneficial to improving the practicality of the voltage-equalizing electrode scaling degree detection device.

[0066] In one embodiment of the present application, see Figure 1 and Figure 2The second platform 12 includes a platform 121, a side column 122 arranged on one side of the platform 121, and a horizontal column 123 slidably arranged on the side column 122 along the vertical direction. The horizontal column 123 extends to the top of the detection area 13, and the X-ray acquisition unit 50 is installed on the horizontal column 123.

[0067] Specifically, the platform 121, the side pillars 122 and the cross pillars 123 cooperate to form a detection area 13 with three openings. Since the cross pillars 123 are slidably arranged on the side pillars 122 in the vertical direction, when the cross pillars 123 slide in the vertical direction on the side pillars 122, the X-ray source 40 is driven to slide up and down.

[0068] Optionally, the X-ray collection unit 50 is installed inside the platform 121 .

[0069] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
