Description

Technical Field

[0001] This invention relates to the field of lightning protection testing technology, and in particular to a mobile lightning protection device testing vehicle system. Background Technology

[0002] Traditional lightning protection testing requires disassembling and sending the equipment for testing, which has problems such as long cycle, high cost, and risk of damage during secondary handling.

[0003] Existing patents, such as CN205749749U, which discloses "A Multifunctional Lightning Protection Detection Vehicle System," only implement the detection of lightning protection devices and soil resistivity. They do not detect direct lightning strikes, induced lightning strikes, or grounding resistance. For example, CN222506448U only implements the lifting and lowering of the lightning protection unit and does not integrate multiple types of detection modules. CN223052391U only optimizes grounding resistance, and its detection function is limited.

[0004] Therefore, there is an urgent need for a mobile lightning protection device testing vehicle system to solve the problems of existing lightning protection testing devices having limited functionality, insufficient mobility, and poor adaptability to various scenarios. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile lightning protection device testing vehicle system, which aims to solve the problems of existing lightning protection testing devices having limited functionality, insufficient mobility, and poor adaptability to various scenarios.

[0006] To achieve the above objectives, the present invention provides a mobile lightning protection device testing vehicle system, including a truck body, a direct lightning strike detection module, an induced lightning strike detection module, a grounding resistance detection module, an insulation resistance detection module, an undercarriage structure interface, and a data processing terminal; the undercarriage structure interface is mounted on one side of the truck body, the data processing terminal is disposed inside the truck body and connected to the undercarriage structure interface, and the direct lightning strike detection module, the induced lightning strike detection module, the grounding resistance detection module, and the insulation resistance detection module are respectively connected to the undercarriage structure interface.

[0007] The direct lightning strike detection module includes a first console, a first display screen, and a voltage divider. The first display screen is fixedly connected to the first console and is located on the top of the first console. The voltage divider is located on one side of the first console.

[0008] The lightning detection module includes a second console, a second display screen, a thundercloud panel, an insulating connecting post, and a grounding electrode. The second display screen is fixedly connected to the second console and is located on top of the second console. The grounding electrode is located on one side of the second console. The insulating connecting post is fixedly connected to the grounding electrode and is located on top of the grounding electrode. The thundercloud panel is fixedly connected to the insulating connecting post and is located on the side of the insulating connecting post away from the grounding electrode.

[0009] The grounding resistance detection module is an ETCR2900 high-precision grounding resistance tester, and the insulation resistance detection module is an ETCR3580B online insulation resistance monitor.

[0010] The width, height, and length of the truck body are 1700mm*1900mm*2950mm.

[0011] This invention discloses a mobile lightning protection device testing vehicle system. The direct lightning strike detection module is equipped with an impulse current testing system (GPP-ICGG-100C) to generate a lightning strike (200kV) voltage wave + (10 / 350μs) current waveform in real time. This verifies the current carrying capacity of equipment (lightning rods, down conductors, etc.). The induced lightning strike detection module is equipped with a combined wave + impulse voltage testing system (GPP-VCWC-2017) to generate a lightning strike (1.2 / 50μs) voltage wave + (8 / 20μs) current waveform in real time, simulating transient overvoltages and overcurrents generated by induced lightning, and verifying the surge resistance of equipment (surge protection devices (SPDs), electronic information systems). The grounding and insulation resistance detection module is equipped with an ETCR2900 high-precision grounding resistance tester, employing six measurement methods—two-pole AC, two-pole DC, three-pole, four-pole, current clamp selection method, and dual-clamp head method without auxiliary poles—to measure grounding resistance. The resistance resolution of the grounding path of the measuring equipment is ≤0.01Ω. Verify the grounding resistance of equipment (grounding grid, down conductors, lightning rods, etc.). The insulation resistance detection module tests at a voltage of 50~500V and a resistance of 100kΩ~20GΩ. Verify the insulation resistance of equipment (surge protectors (SPDs), electronic information systems). The data processing terminal uses a Nanjing Yanwei rugged laptop, configured with an i7-1165G7 processor, 16GB of onboard memory, and a 500GB hard drive. The Intel® Core™ i7-1165G7 is a quad-core, eight-thread processor with a base frequency of 2.8GHz and a maximum turbo frequency of 4.7GHz, and features a 14-inch display. The machine interface is a DB9 RS232 serial port.

[0012] The truck body serves as the carrier, integrating the vehicle-mounted structure and the undercarriage structure. It achieves mobile testing of three types of lightning protection through a two-level "signal-data" collaborative mechanism. The direct lightning strike detection module is an impulse current testing system (GPP-ICGG-100C). The lightning rod and down conductor of the device under test are connected to the impulse current testing system, which generates a lightning strike (200kV) voltage wave + (10 / 350μs) current waveform to impact the device under test in real time. The status of the lightning rod, down conductor, and other equipment is detected. The detected data is transmitted to the data processing terminal through the undercarriage structure interface. The induced lightning strike detection module is a combined wave + impulse voltage testing system (GPP-VCWC-2017). The surge protector (SPD) and electronic information system of the device under test are connected to the combined wave + impulse voltage testing system, which generates a lightning strike (1.2 / 50μs) voltage wave + (8 / 20μs) current waveform to impact the device under test in real time. The status of the surge protector (SPD) and electronic information system equipment is detected. The tested data is transmitted to the data processing terminal via the under-vehicle structure interface. The grounding resistance detection module is an ETCR2900 high-precision grounding resistance tester. The tested grounding grid, down conductor, lightning rod, etc., are connected to the grounding resistance tester using various measurement methods such as two-pole AC, two-pole DC, three-pole, four-pole, current clamp selection method, and dual-clamp head method without auxiliary poles to measure the resistance value of the equipment's grounding path. The grounding resistance of the grounding grid, down conductor, lightning rod, etc., is detected. The tested data is transmitted to the data processing terminal via the under-vehicle structure interface. The insulation resistance detection module is an ETCR3580B online insulation resistance monitor. The tested surge protection device (SPD) and electronic information system are connected to the online insulation resistance monitor to measure the insulation resistance of the equipment. The tested data is transmitted to the data processing terminal via the under-vehicle structure interface. The data processing terminal collects data from the lightning protection devices (lightning rod, down conductor, grounding grid, SPD, etc.) through the under-vehicle structure, analyzes the data using software to determine the status of the tested equipment, and issues a judgment result of good, qualified, or unqualified. The system reminds users whether their lightning protection devices are intact. By integrating three detection modules—direct lightning strike, induced lightning, and grounding system—with mobile lightning protection equipment used by the military, the system enables simultaneous detection of three types of lightning protection signals, rapid deployment on mobile platforms, and coverage in multiple scenarios, including mountainous communication base stations, petrochemical plant areas, and railway electrification facilities. It boasts a detection probability of ≥95% and improves mobility by 40%, thus solving the problems of existing lightning protection detection devices such as limited functionality, insufficient mobility, and poor adaptability to multiple scenarios.

Software analysis determines the status of the tested equipment, providing a judgment of "good," "qualified," or "unqualified." This alerts the user to check the condition of the lightning protection device. By integrating three detection modules—direct lightning strike, induced lightning, and grounding system—with mobile lightning protection equipment, this system enables simultaneous detection of three lightning protection signals, rapid deployment on mobile platforms, and coverage across multiple scenarios, including mountainous communication base stations, petrochemical plant areas, and railway electrification facilities.
