Description

TECHNICAL FIELD

[0001] The utility model relates to lightning stroke monitoring device technical field, especially, a lightning stroke monitoring device with comprehensive protection is provided. BACKGROUND

[0002] The lightning stroke monitoring device with comprehensive protection is the core equipment of modern intelligent lightning protection system, and is widely applied to key facilities such as electric power, communication and new energy. Its structure is mainly composed of three units of sensing, protection and analysis. The sensing unit usually adopts sensors such as Rogowski coil, and captures lightning current in a non-contact mode. The protection unit is where its unique value lies, and integrates multiple level surge protectors (such as spark gap and voltage-dependent resistor), like a "firewall", to discharge a large part of lightning energy, and clamp the residual voltage to a safe level, to ensure that the device itself survives in lightning. The analysis unit processes the collected current waveform at high speed, and accurately extracts key parameters such as peak value and energy. Its operating principle is: the sensor senses lightning current → the protection unit immediately acts to protect itself → the acquisition system records the waveform → the processor analyzes the data and uploads the results to the background through the communication interface. The device not only provides accurate data for lightning accident investigation, but also evaluates the state of the lightning protection system through long-term monitoring, and is an important tool for realizing predictive maintenance and improving system reliability.

[0003] At present, the conventional lightning stroke monitoring device with comprehensive protection is mostly installed at a high place for application. Its specific installation mode is to be fixed on the supporting base surface by bolt fixing. Since the overall structure of the device is optimized, the area of the base is usually not too large, which causes the contact area on the ground to be small in actual installation, and the stability after installation is poor.

Therefore, a lightning stroke monitoring device with comprehensive protection is proposed. UTILITY MODEL CONTENTS

[0038] Embodiment two

[0039] The lightning monitoring device with comprehensive protection provided in embodiment one is further optimized, specifically, as Figure 4As shown, the auxiliary support plate 42 extends a planar end 43 away from one end of the auxiliary connecting seat 41, the top of the planar end 43 is screw-fitted with a fastening bolt 44, one end of the fastening bolt 44 is screw-firmly connected with the support plate 52;

[0040] As shown, the monitoring device in this state is a storage state, when it is needed to be unfolded and applied, the support plate 52 is turned outwards to a horizontal state to keep parallel with the bottom of the support column 1, the rotation adjusting ring 3 is rotated to form a threaded cooperation with the support column 1, so that the movable ring 31 can be driven to slide along the height direction of the support column 1, and finally the bottom of the movable ring 31 is abutted against the surface of the support plate 52 to form a pressing action; Figure 2

[0041] The bottom of the movable ring 31 is fixed with a pressing block 32, and the pressing block 32 is correspondingly arranged with the connecting seat 51;

[0045] Embodiment three

[0046] The lightning monitoring device with comprehensive protection provided in embodiment one or two is further optimized, as shown in the figure, the lightning monitoring unit 2 includes a lightning monitoring sensing assembly 21 and a comprehensive protection assembly 22; Figure 6

[0047] The lightning monitoring sensing assembly 21 includes a lightning current sensor, a signal processing module and a signal acquisition module;

[0048] ​​When lightning strikes or is attracted to the protected facility (such as lightning rod, line), the huge lightning current will flow into the ground along the down conductor. At this time, the Rogowski coil (lightning current sensor) wrapped on the down conductor instantaneously senses the dramatic change of current and outputs a corresponding voltage signal. After the analog signal from the lightning current sensor is preliminarily processed by the signal acquisition module, it is sent to the high-speed ADC for digital sampling. The core processor of the signal processing module analyzes these digital signals in real time, calculates the key parameters of lightning current, including: peak current (Imax), wave head time (T1), half peak value time (T2), charge quantity (Q) and specific energy (W / R) and the like. The processed lightning parameters (time, place, intensity, energy, etc.) are immediately uploaded to the background monitoring center through the communication interface. The structure, principle, arrangement method and use method of the lightning strike monitoring sensor assembly 21 described above are all technical common knowledge known to those skilled in the art, so no further elaboration is needed in this embodiment.

[0049] The comprehensive protection assembly 22 includes an input interface area 220, a first protection area 221, a second protection area 222, a third protection area 223 and a grounding row 224, which are connected in turn by wires.

[0050] The first protection area 221 is connected to the grounding row 224 through a discharge path one, the second protection area 222 is connected to the grounding row 224 through a discharge path two, and the third protection area 223 is connected to the grounding row 224 through a discharge path three.

[0051] Inductors (decoupling coils) or resistors are usually used to connect between the above protection levels. The role of these elements is to generate sufficient impedance to ensure that the voltage difference between the protection devices at the moment of lightning strike is large enough, so that they can be reliably started in order (first protection area 221, then second protection area 222, and finally third protection area 223). A large area of ground copper foil will be designed on the circuit board, and the ground pins of all protection devices are connected to this ground plane through short and thick wires, and finally to the external ground terminal.

[0052] Protection process:

[0053] 1. First level (rough discharge): When a huge lightning current flows in, the spark gap first breaks down instantaneously, directly discharging most of the energy into the ground.

[0054] 2. Second level (clamping voltage limiting): The remaining overvoltage continues to impact inward, and the voltage of the voltage-dependent resistor is clamped to a lower level.

[0055] 3. Third stage (fine protection): Finally, the transient suppression diode and filter circuit perform the final fine processing to reduce the residual voltage to a range that the chip can safely withstand.

[0056] Protection principle: Based on the different starting voltage and response speed characteristics of each protection element. Through the energy coordination of inductors and other elements, it is ensured that they start in order. The ultimate goal is to layer by layer weaken the lightning pulse energy into a weak and safe signal, so as to ensure that the core monitoring circuit behind is still intact and works normally after lightning strike.

[0057] The above structure, principle, arrangement method and use method of the comprehensive protection assembly 22 are all technical common knowledge known by those skilled in the art, so no further elaboration is needed in the embodiment.

[0058] In the utility model, unless another definite provision and limitation, the terms "mount", "connect", "link", "fix" and the like terms should be understood in broad sense, for example, can be fixed connection, also can be detachable connection, or be integrated; can be mechanical connection, also can be electrical connection or each other can communicate; can be directly connected, also can be indirectly connected through intermediate medium, can be the communication or the interaction of two elements of two elements inside, unless another definite limitation.
