Description

Technical Field

[0001] This utility model relates to the field of dry-type shunt reactor technology, and in particular to an external insulation test system for dry-type shunt reactors that takes into account the influence of complex environments. Background Technology

[0002] Currently, given the numerous advantages of dry-type reactors, the demand for 220kV and above dry-type parallel reactors in domestic and international power grid projects is increasing, making the development of higher voltage-level dry-type parallel reactor products inevitable. To improve the reliability of ultra-high voltage direct current (UHVDC) projects, there is an urgent need to develop a highly reliable 500kV dry-type parallel reactor. Simultaneously, to fully verify and evaluate the performance of the prototype developed for the project, it is necessary to conduct performance testing on the reactor's external insulation and assess the weather resistance of the dry-type parallel reactor's insulation system.

[0003] The use of composite insulation materials to replace traditional materials is a trend in the development of high-end power equipment. However, the performance of composite insulation equipment (organic synthetic insulators, dry-type reactors, dry-type transformers, etc.) gradually declines after long-term corrosion from the operating environment, leading to operational accidents. Currently, traditional testing systems are used to evaluate the performance of composite insulators. However, composite insulators are small in size, and the current after voltage application is very small, resulting in reduced accuracy of the tests. Traditional testing systems are not suitable for dry-type parallel reactors. Therefore, there is an urgent need to construct a testing system that considers the influence of complex environmental factors to conduct accelerated aging tests on composite insulation equipment under simulated operating conditions and to assess the operational reliability of the equipment.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2This utility model discloses an external insulation test system 1 for dry-type parallel reactors that considers the influence of complex environments. It includes an insulated test chamber 10, a high-voltage test power supply 20, a remote and on-site monitoring device 30, an air circulation heating and humidification device 40, a salt spray device 50, a lighting device 60, and a spraying device 70. The insulated test chamber 10 forms a test cavity, where the dry-type parallel reactor to be tested is placed. The high-voltage test power supply 20 is located outside the insulated test chamber 10. The air circulation heating and humidification device 40 and the lighting device 60 are both located inside the test cavity. The monitoring terminal of the remote and on-site monitoring device 30 is located inside the test cavity. The salt spray device 50... Both the spray end of the test chamber 10 and the spray end of the spray device 70 are located inside the test cavity. The high-voltage test power supply 20 is used to apply test voltage and test current to the dry-type parallel reactor under test. Compared with the traditional test system, this setup, by including the thermal insulation test chamber 10, the high-voltage test power supply 20, the remote and on-site monitoring device 30, the air circulation heating and humidification device 40, the salt spray device 50, the light device 60, and the spray device 70, enables the assessment of the external insulation performance of the dry-type parallel reactor under the influence of complex environments, evaluates the weather resistance of the insulation system of the dry-type parallel reactor, and improves the operational reliability of the dry-type parallel reactor. At the same time, it improves the accuracy of the assessment.

[0025] Specifically, the test cavity is rectangular in shape, and its length and width should be more than three times the length and width of the dry-type parallel reactor to be tested, respectively, to ensure that the distance between the inner wall of the insulation test chamber 10 and the dry-type parallel reactor is not less than the length and width of the reactor body. The height of the test cavity should be more than twice the height of the dry-type parallel reactor to be tested, to ensure that the distance between the top of the insulation test chamber 10 and the top surface of the dry-type parallel reactor is not less than the height of the reactor body.

[0026] During the test, the high-voltage test power supply 20 can simultaneously apply full voltage and full current to the dry-type shunt reactor under test. The applied voltage is adjustable from 0-66kV. For the power supply circuit, when the continuous resistive current load is 250mA (rms), the maximum voltage drop within 1 second should not exceed 5%. The protection level should be adjusted to 1A (rms). The applied current, for the dry-type shunt reactor, is adjustable from 0 to 1000A, flowing through the capacitor tower to the reactor circuit.

[0027] In this embodiment, the remote and on-site monitoring device 30 includes a monitoring computer and a monitoring instrument. The monitoring instrument is installed inside the test cavity, and the monitoring computer is installed outside the thermal insulation test chamber 10. The monitoring computer and the monitoring instrument are communicatively connected, and there is wireless data interaction between the monitoring computer and the monitoring instrument. The wireless data interaction includes: monitoring instructions issued by the monitoring computer to the monitoring instrument and / or monitoring data uploaded by the monitoring instrument to the monitoring computer.

[0028] The monitoring software in the monitoring computer can display the test status in real time and monitor the operating status of each device in real time; at the same time, it can display the corresponding parameters and historical curves; and it can control the test process such as setting and modifying parameters for each device.

[0029] Specifically, in this embodiment, the monitoring software in the monitoring computer uses the S7 series programmable controller produced by the German company SIEMENS as the central processing unit, equipped with digital I / O modules and analog I / O modules, and has an internal PID operation controller function. The human-machine interface (HMI) adopts the CNC 8070 series color LCD touch screen, and the control interface is displayed in full Chinese. The power-on display shows the LOGO and a brief and clear display of the test chamber maintenance precautions. It has three-level (operation / management / maintenance) and four-state (browse / programming (call) / modify running parameters / maintenance settings) password protection functions.

[0030] Furthermore, in this embodiment, the thermal insulation test chamber 10 includes a first panel and four second panels. The four second panels are connected end to end to form a cuboid frame. The first panel covers the top of the cuboid frame, and the bottom of the cuboid frame is inserted into a concrete base plate. One of the second panels has an inlet that communicates with the test cavity and has a rotating door.

[0031] Specifically, the rotating door is rotatably connected to the second storage panel via hinges, and the rotating door consists of two doors that open left and right. Each door is equipped with a first observation window, and the opposite outer walls of the insulation test chamber 10 are each equipped with a second observation window. Figure 2 Taking the orientation shown as an example, a second observation window is provided on both the left and right outer walls of the thermal insulation test chamber 10.

[0032] For example, the thermal insulation test chamber 10 has a capacity of 72m³. 3 The dimensions are 6000mm × 6000mm × 3000mm (length × width × height). The bottom of the observation window is approximately 1300mm from the ground. Figure 2 Taking the orientation shown as an example, a rotating door is set at the front end of the thermal insulation test chamber 10, with a width × height of 4000mm × 2500mm.

[0033] The first silo panel includes a first stainless steel plate, a first epoxy plate, and a first rock wool plate. The first stainless steel plate and the first epoxy plate are arranged opposite to each other, and the first rock wool plate is sandwiched between the first stainless steel plate and the first epoxy plate.

[0034] Specifically, the space between the first stainless steel plate and the first epoxy plate is filled with a first rock wool board. During installation, the first stainless steel plate faces the inside of the experimental cavity, and the first epoxy plate faces the outside of the experimental cavity.

[0035] In this embodiment, the second storage plate includes a second stainless steel plate, a second epoxy plate, and a second rock wool plate. The second stainless steel plate and the second epoxy plate are arranged opposite to each other, and the second rock wool plate is sandwiched between the second stainless steel plate and the second epoxy plate.

[0036] Specifically, a second rock wool board is used to fill the space between the second stainless steel plate and the second epoxy plate. During installation, the second stainless steel plate faces the inside of the experimental cavity, and the second epoxy plate faces the outside of the experimental cavity.

[0037] Since the thermal insulation test chamber 10 needs to withstand salt spray corrosion and also needs to have a certain thermal insulation effect, the enclosure structure is composed of stainless steel plates, rock wool boards and epoxy boards.

[0038] The thickness of both the first and second rock wool boards ranges from 90mm to 120mm. In this embodiment, the thickness of both the first and second rock wool boards is 100mm.

[0039] Continue to refer to Figure 3 In this embodiment, the air circulation heating and humidification device 40 includes a refrigeration evaporator 41, a dehumidification evaporator 42, a heater 43, a humidifier 44, a fan impeller 45, and a fan motor 46. A partition plate is provided inside the test cavity enclosed by the insulation test chamber 10, dividing the test cavity into an air duct interlayer 11 and a test chamber 12. The dry-type parallel reactor to be tested is placed in the test chamber 12. An air inlet and an air outlet are provided on the partition plate. The fan impeller 45, heater 43, refrigeration evaporator 41, and... The dehumidifying evaporators 42 are all installed inside the air duct interlayer 11. The fan impeller 45, heater 43, refrigeration evaporator 41 and dehumidifying evaporator 42 are arranged from top to bottom. The fan motor 46 is installed on the outer wall of the thermal insulation test chamber 10. The output shaft of the fan motor 46 extends through the outer wall of the thermal insulation test chamber 10 into the air duct interlayer 11 and is connected to the fan impeller 45. By setting the fan impeller 45 and the fan motor 46, the uniformity of temperature and humidity in the test chamber 12 is ensured, and the accuracy of the test is improved.

[0040] The humidifier 44 is installed on the outer wall of the thermal insulation test chamber 10. The output end of the humidifier 44 extends through the outer wall of the thermal insulation test chamber 10 into the air duct interlayer 11. The output end of the humidifier 44 is located between the fan impeller 45 and the heater 43.

[0041] It should be noted that the refrigeration evaporator 41, dehumidification evaporator 42, heater 43, humidifier 44, fan impeller 45 and fan motor 46 are all devices well known to those skilled in the art, and the structure of the refrigeration evaporator 41, dehumidification evaporator 42, heater 43, humidifier 44, fan impeller 45 and fan motor 46 will not be described in detail here.

[0042] Specifically, the output of heater 43 is controlled according to the temperature / humidity points set by the monitoring software in the monitoring computer, ultimately achieving a dynamic balance. During the test, the fan motor 46 is started to circulate the air in the test chamber 12. When the fan motor 46 rotates at high speed, it draws the air in the test chamber 12 into the air duct interlayer 11 from the bottom. After being heated / cooled and humidified / dehumidified, the air is blown out from the air outlet below the air duct interlayer 11. The air that has exchanged with the test sample in the test chamber 12 is then drawn into the air duct interlayer 11 through the air inlet, and the cycle repeats to achieve the set temperature requirements. This is a structure with bottom air outlet and top air return.

[0043] Continue to refer to Figure 2 In this embodiment, the salt spray device 50 includes an electric peristaltic pump 52, a salt solution flow meter 53, a salt water container, a water tank, and a spray unit. The salt water container contains salt water of a preset concentration. The salt solution flow meter 53 is installed inside the salt water container, which is located inside the water tank. A water level controller is installed inside the water tank. The input end of the electric peristaltic pump 52 is connected to the water level controller via a connecting pipe, and the output end of the electric peristaltic pump 52 is connected to the spray unit via a connecting pipe. The spray unit is located inside the test cavity. The salt solution flow meter 53 is used to measure the flow rate of the salt water. The water level controller is used to control the amount of water entering the electric peristaltic pump 52.

[0044] Specifically, a salt solution of a certain concentration is prepared manually and placed in a salt solution container. The electric peristaltic pump 52, the salt solution flow meter 53, the salt solution container, and the water tank are all located outside the insulated test chamber 10, while the spray unit is located inside the test chamber 12.

[0045] During the experiment, the flow rate of the salt solution can be controlled by the rotation speed of the electric peristaltic pump 52, and the flow rate of the salt solution can be directly read by the salt solution flow meter 53.

[0046] It should be noted that the electric peristaltic pump 52, the brine flow meter 53, and the water level controller are all devices well known to those skilled in the art, and their structures will not be described in detail here.

[0047] Furthermore, in this embodiment, the spray unit includes a salt spray nozzle 51 and a salt spray tank. The salt spray tank is disposed on the inner bottom surface of the test cavity, and the nozzle is disposed on the inner side wall of the test cavity. The nozzle is connected to the salt spray tank through an installation pipe, and the output end of the electric peristaltic pump 52 is connected to the salt spray tank through a connecting pipe.

[0048] Specifically, the nozzles are installed on the salt spray chamber at a height of 1200mm above the ground. There are 12 nozzles, each with a flow rate of 7.1L / H and an air consumption of 115L / min.

[0049] Furthermore, in this embodiment, the illumination device 60 includes a xenon lamp, which is disposed on the inner wall of the test cavity.

[0050] The xenon lamp is vertically mounted on the inner wall of the test chamber 12. The xenon lamp is exposed to sunlight and is a device that emits high heat. To prevent the high heat from affecting the test temperature and the test specimen, the heat emitted by the xenon lamp is removed by the refrigeration evaporator 41.

[0051] Specifically, the number and power of the xenon lamps are 6×6500W, with a lifespan of approximately 1900h, and the installation distance is 550mm from the test sample.

[0052] It should be noted that the structure of a xenon lamp is well known to those skilled in the art, and will not be described in detail here.

[0053] Continue to refer to Figure 4 In this embodiment, the spray device 70 includes a rainwater tank 71, a shut-off valve 72, a water filter 73, a variable frequency booster pump 74, a spray solenoid valve 75, and a spray support 76. The spray support 76 is disposed in the test cavity. The rainwater tank 71 contains liquid. The shut-off valve 72 is connected to the rainwater tank 71 through a first pipe 77. The end of the shut-off valve 72 away from the first pipe 77 is connected to the water filter 73 through a second pipe 78. The end of the water filter 73 away from the second pipe 78 is connected to the input end of the variable frequency booster pump 74 through a third pipe 79. The output end of the variable frequency booster pump 74 is connected to the spray solenoid valve 75 through a fourth pipe 80. The end of the spray solenoid valve 75 away from the fourth pipe 80 is connected to the bottom end of the spray support 76 through a fifth pipe 81. A plurality of rainwater nozzles 761 are disposed on the spray support 76 at intervals.

[0054] The rain nozzle 761 is made of copper, which improves its corrosion resistance. The angle of the rain nozzle 761 is adjustable during installation.

[0055] For example, the shut-off valve 72 is a manual shut-off valve 72, but of course, the shut-off valve 72 can also be an electric shut-off valve 72.

[0056] It should be noted that the rain shower head is a component well known to those skilled in the art, and its structure will not be described in detail here.

[0057] The spray bracket 76 is Y-shaped. In this embodiment, there are four spray brackets 76. The four spray brackets 76 are respectively set at the four corners of the test chamber 12. Each spray bracket 76 is equipped with multiple rain nozzles. The spray bracket 76 is connected to the five-way fitting on the fifth pipe body 81 through a quick-connect coupling.

[0058] Specifically, the rain tank 71, the shut-off valve 72, the water filter 73, the variable frequency booster pump 74, and the spray solenoid valve 75 are all located outside the thermal insulation test chamber 10.

[0059] During the test, the rain angle was 45°, and the pressure of the rain nozzle 761 was ≥375kPa. An automatic water replenishment system was adopted. The spray device 70 has the function of automatically detecting water level and replenishing water. That is, a water level monitor is installed in the rain water tank 71. When the water level in the rain water tank 71 drops to the preset water level, the water level detector sends a signal to the monitoring software in the monitoring computer, and the monitoring software sends a water replenishment signal to replenish water.

After two hours of rain exposure, the spray device 70 is closed, and the lighting device 60 is opened to conduct a solar radiation simulation test on the dry-type parallel reactor under test. After two hours of irradiation, the lighting device 60 is closed, and the high-voltage test power supply 20 is opened, applying full voltage to the dry-type parallel reactor under test for an electro-erosion test. After two hours of electro-erosion, the high-voltage test power supply 20 is turned off, and then... Figure 5 The experiment was conducted sequentially until it was completed.
