[0020] In order to improve the problem of unreliable measurement results of the spectrometer due to insufficient vibration protection, the embodiments of the present application provide the following solution.

[0021] Example 1: Please refer to Figures 1 to 7 The embodiment of the present application provides a dual-band fault arc identification device based on spectral features. The dual-band fault arc identification device and method based on spectral features include: a shock absorbing mechanism 2; a box 1, which is arranged on the shock absorbing mechanism 2; a first optical fiber spectrometer 3 and a second optical fiber spectrometer 4, which are arranged on the box 1, and the box 1 is also provided with a box door 11, and the box door 11 is provided with a handle 12, and the box 1 is provided with a display screen 5.

[0022] In some embodiments, please refer to Figures 1 to 5The shock absorbing mechanism 2 includes a lateral shock absorbing assembly 22, and the lateral shock absorbing assembly 22 includes a first support plate 221, a second support plate 225 and a third support plate 229. The first support plate 221 is arranged at the bottom of the box body 1, and the second support plate 225 is slidably arranged along the first direction on the side of the first support plate 221 away from the box body 1, and the third support plate 229 is slidably arranged along the second direction on the side of the second support plate 225 away from the first support plate 221, and the first direction forms an angle with the second direction. The lateral shock absorbing assembly 22 also includes: a first slide rail 222, which is arranged on a side of the first support plate 221 away from the box body 1; a first slider 223, which is arranged on a side of the second support plate 225 away from the third support plate 229; a first limit block 224, which is arranged on the first slide rail 222; a second slide rail 226, which is arranged on a side of the second support plate 225 away from the first support plate 221; a second slider 227, which is arranged on an end of the third support plate 229 away from the support column 214; a second limit block 228, which is arranged on the second slide rail 226; a clamping and fixing block 220, which is arranged on an end of the first support plate 221 away from the second support plate 225, and the first support plate 221 is arranged on the box body 1 through the clamping and fixing block 220.

[0023] With such arrangement, during the travel of the high-speed railway, when the high-speed railway starts and brakes, the second slide rail 226 on the second support plate 225 moves forward or backward on the second slider 227, and at the same time, the second limit block 228 on the second slide rail 226 is placed to prevent the equipment from falling off when the brake is too sharp. At the same time, when the high-speed railway turns, the first slide rail 222 on the first support plate 221 moves left or right on the first slider 223 to slow down the travel of the equipment, and at the same time, the first limit block 224 on the first slide rail 222 is placed to prevent the equipment from falling off when the turn is too sharp, thereby reducing the problem of unreliable measurement results of the spectrometer due to the vibration of the inertia of the equipment. In this way, when the high-speed railway starts and brakes, the second slide rail 226 can move forward or backward on the second slider 227. This design enables the equipment to be adjusted accordingly according to the acceleration and deceleration of the high-speed railway, reducing the displacement and stress of the equipment caused by inertia. When the high-speed railway turns, the first slide rail 222 can move left or right on the first slider 223. Move left or right. This design allows the equipment to make corresponding adjustments according to the turning conditions of the high-speed rail, reducing the vibration and stress of the equipment caused by centrifugal force. The second limit block 228 prevents the equipment from falling off the slide rail due to excessive inertia when braking too sharply. This design provides additional safety protection to ensure that the equipment can still remain in the predetermined position under extreme conditions. The first limit block 224 prevents the equipment from falling off the slide rail due to excessive centrifugal force when turning too sharply. This design also provides additional safety protection to ensure that the equipment will not fall off when turning at high speed. Through the structural design of the slide rail and the slider, the equipment can move more smoothly during the high-speed rail operation, reducing the vibration and stress caused by sudden movement and sudden stop. This design allows the equipment to maintain a relatively stable state under various driving conditions. The movement and adjustment of the equipment during the start, braking and turning of the high-speed rail can effectively reduce the influence of the equipment inertia, thereby reducing the problem of unreliable spectrometer measurement results caused by the inertial vibration of the equipment.

[0024] In some embodiments, please refer to Figures 1 to 6The shock absorbing mechanism 2 also includes a damping shock absorbing component 21, which includes: a support column 214, which is arranged on the side of the third support plate 229 away from the second support plate 225; a fixing seat 215, on which a shock absorbing groove and a round hole are opened, the round hole is connected to the shock absorbing groove, and the fixing seat 215 is sleeved on the support column 214 through the round hole so that the support column 214 partially extends into the shock absorbing groove; a limiting plate 213, which is arranged on the support column 214 away from the third support plate 229 On one end, the diameter of the limit plate 213 is larger than the diameter of the circular hole; the damper 212 is arranged in the shock absorbing groove and is located on the side of the limit plate 213 away from the support column 214, and the opposite ends of the damper 212 are respectively connected to the limit plate 213 and the fixed seat 215; the shock absorbing spring 211, the shock absorbing spring 211 is sleeved on the damper 212, one end of the shock absorbing spring 211 abuts on the fixed seat 215, and the other end of the shock absorbing spring 211 abuts on the limit plate 213.

[0025] With such arrangement, when the high-speed rail is running unsteadily, the damping shock absorbing assembly 21 supports the limit plate 213 device through the shock absorbing spring 211, the limit plate 213 supports the support column 214, and the damper 212 is sleeved in the shock absorbing spring 211 to assist the use of the shock absorbing spring 211. The damper 212 is usually suitable for high-frequency vibration and small amplitude, while the shock absorbing spring 211 is suitable for low-frequency vibration and large amplitude. The two are used in combination to achieve effective isolation of vibrations of different frequencies, thereby comprehensively improving the shock absorption effect. In this way, the shock-absorbing spring 211 is mainly used to absorb and buffer low-frequency vibrations and large-amplitude impacts. When the high-speed rail is running unsteadily, the shock-absorbing spring 211 can effectively reduce the displacement and stress of the equipment caused by large-amplitude vibrations. The damper 212 is sleeved in the shock-absorbing spring 211. The damper 212 is usually suitable for high-frequency vibrations and small amplitudes. It reduces the vibration amplitude by consuming vibration energy, especially in high-frequency vibrations, it can quickly absorb and dissipate energy. Through the combined design of the shock-absorbing spring 211 and the damper 212, the equipment can be more stable during movement, reducing mechanical wear caused by vibration and stress, which helps to extend the service life of the equipment and reduce maintenance and replacement costs. The stable equipment state and reduced vibration enable the equipment to maintain a good working state under various driving conditions and reduce the failure rate. The limit plate 213 supports the support column 214, which can prevent the equipment from falling off in extreme cases and provide additional safety protection, which is very important for ensuring the safety of equipment and personnel. Through a comprehensive shock-absorbing design, it can reduce accidental damage to the equipment caused by vibration and impact, and improve the reliability of the equipment in harsh environments.

[0026] In some embodiments, please refer to Figures 1 to 7The housing 1 is also provided with a temperature control assembly 23, and the temperature control assembly 23 includes: a fixing plate 13, which is provided on the housing 1, and the first optical fiber spectrometer 3 and the second optical fiber spectrometer 4 are provided on the housing 1 through the fixing plate 13; a fan bracket 230, the fixing plate 13 is provided with a connection hole 15, the first support plate 221 and the housing 1 are provided with a square hole, and the fan bracket 230 is provided on the fixing plate 13 through the connection hole 15 and the square hole; an air inlet plate 231, which is provided on the fan bracket 230, and the air inlet plate 231 is provided with an air inlet hole 232; a motor 235, which is provided on the side of the air inlet plate 231 away from the first optical fiber spectrometer 3 and the second optical fiber spectrometer 4; a cooling fan 236, which is provided on the motor 235, and the cooling fan 236 and the motor 235 The output shaft is coaxially driven; an air outlet plate 233 is arranged on the end of the fan bracket 230 away from the air inlet plate 231, and an air outlet hole 234 is opened on the air outlet plate 233. A plurality of heat dissipation holes 14 are opened on the fixing plate 13. The box body 1 and the first support plate 221 are provided with fixing holes, and heat dissipation wings 237 are arranged through the fixing holes. The second support plate 225 is provided with acceleration ventilation holes 238, and the acceleration ventilation holes 238 include an air inlet portion 2381, an acceleration portion 2382 and an air outlet portion 2383. The diameter of the air inlet portion 2381 is equal to the diameter of the air outlet portion 2383, and the diameter of the acceleration portion 2382 is smaller than the diameters of the air inlet portion 2381 and the air outlet portion 2383. The third support plate 229 is provided with a square hole, and a radiator 239 is fixedly arranged through the square hole.

[0027] With such arrangement, since the spectrometer needs to be cooled during long-term operation, the motor 235 is turned on to rotate the cooling fan 236, so that heat is sucked in through the air inlet hole 232 on the air inlet plate 231 and discharged from the air outlet hole 234 on the air outlet plate 233. The heat dissipation holes 14 and the heat dissipation fins 237 on the box body 1 assist in heat dissipation. At the same time, the heat is discharged from the air outlet hole 234 and then enters the acceleration ventilation hole 238 to accelerate the heat dissipation speed. At the same time, the heat is dissipated through the radiator 239 of the third support plate 229 to accelerate the heat discharge. At the same time, there is a gap between the first support plate 221, the second support plate 225 and the third support plate 229 to assist in heat dissipation. In this way, by turning on the motor 235 to rotate the cooling fan 236, the heat is actively sucked in from the air inlet hole 232 on the air inlet plate 231 and discharged from the air outlet hole 234 on the air outlet plate 233. This active heat dissipation method can quickly take away the heat inside the device. The heat dissipation holes 14 and the heat dissipation wings 237 on the box body 1 serve as auxiliary heat dissipation means to further increase the heat discharge area and efficiency. This passive heat dissipation method can still maintain a certain heat dissipation effect when the fan stops or runs at a low speed. After the heat is discharged from the air outlet hole 234, it enters the acceleration ventilation hole 238, which can accelerate the heat discharge speed. This design allows the heat to be discharged from the inside of the device faster to prevent heat accumulation inside the device. The radiator 239 on the third support plate 229 further dissipates the heat to accelerate the heat discharge. This multi-function The hierarchical heat dissipation design ensures that heat can be quickly and effectively discharged from the device. There are gaps between the first support plate 221, the second support plate 225 and the third support plate 229. These gaps can assist in heat dissipation. The gaps allow air to circulate inside the device, further improving the heat dissipation efficiency. The gap design promotes air convection, so that heat can be discharged from the device by natural convection. This natural heat dissipation method is particularly important when the device is under low load or the fan is running at a low speed. Through an effective heat dissipation system, the device can be prevented from overheating, thereby protecting the electronic components and precision instruments inside the device, which helps to extend the service life of the device and reduce maintenance and replacement costs. Stable temperature control reduces the failure rate of the device due to overheating, allowing the device to maintain a good working condition during long-term operation.

[0029] The implementation principle of the dual-band arc fault identification device and method based on spectral characteristics in the embodiment of the present application is: First, the device is placed on the high-speed rail, and the optical fiber is placed at the key parts of the high-speed rail, such as inside the electrical cabinet, near the connector, etc. The optical fiber is inserted into the first optical fiber spectrometer 3 and the second optical fiber spectrometer 4, and the transmission content is calibrated through the display screen 5 to ensure that the output signal accurately reflects the arc characteristics, and multiple calibration tests are performed to ensure the stability and reliability of the system; during the travel of the high-speed rail, when the high-speed rail starts and brakes, the second slide rail 226 on the second support plate 225 moves forward or backward on the second slider 227, and the second limit block 228 on the second slide rail 226 is placed to prevent the device from falling off when the brake is too sharp; at the same time, when the high-speed rail turns, the first slide rail 222 on the first support plate 221 moves left or right on the first slider 223 to slow down the travel of the high-speed rail, and the first limit block 224 on the first slide rail 222 is placed to prevent the device from falling off when the turn is too sharp, thereby reducing the problem of unreliable measurement results of the spectrometer due to the vibration of the equipment inertia; at the same time, the damping and shock absorbing component 21 is placed on the high-speed rail During uneven driving, the device is supported by the shock absorbing spring 211, and the damper 212 assists the use of the shock absorbing spring 211. The damper 212 is usually suitable for high-frequency vibration and small amplitude, while the shock absorbing spring 211 is suitable for low-frequency vibration and large amplitude. The two are used in combination to achieve effective isolation of vibrations of different frequencies, thereby comprehensively improving the shock absorption effect. At the same time, since the spectrometer needs to be cooled during long-term operation, the cooling fan 23 is turned on by turning on the motor 235. 6, so that the heat is sucked in through the air inlet hole 232 on the air inlet plate 231, and discharged from the air outlet hole 234 on the air outlet plate 233. The heat dissipation holes 14 and the heat dissipation fins 237 on the box body 1 assist in heat dissipation. At the same time, the heat is discharged from the air outlet hole 234 and enters the acceleration ventilation hole 238 to accelerate the heat dissipation speed. At the same time, the heat is dissipated through the radiator 239 of the third support plate 229 to accelerate the heat discharge. At the same time, there is a gap between the first support plate 221, the second support plate 225 and the third support plate 229 to assist in heat dissipation.
