Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lightning protection device, and particularly relates to a mobile field special container grounding device. BACKGROUND

[0002] In modern war, fixed command system, communication system, weapon equipment and medical logistics supply system have poor anti-destroying ability and are difficult to adapt to the war survival demand under high technology conditions. The mobile small area field combat position, mobile field command post, mobile field hospital, mobile field logistics support warehouse, mobile field communication vehicle (field radar vehicle, field monitoring and monitoring vehicle, communication command vehicle) and mobile small area combat position (radar station, observation and communication station, command center machine room) and other integrated information systems must have the function of shifting and mobile deployment at any time. The combat demand is different under different environmental conditions. The system should be able to resist the attack of enemy "soft damage" and "hard destroy", and also should be able to resist the test of bad environment and climate in nature. Especially, the lightning damage is particularly important. Good grounding device is the most basic guarantee for the success of lightning protection. Once lightning means single and multiple lightning current impact. If the lightning current cannot be released smoothly, the electronic system line and equipment can be seriously damaged. This is a devastating damage to information equipment. If the grounding device is not good and the grounding resistance is too large, the equipment damage and personal safety accidents can be caused by lightning and other overvoltage behaviors. Many military electronic equipment, information equipment, short wave ultra-short wave equipment, radar system equipment, communication equipment, weapon equipment and other equipment itself need good working grounding, high frequency signal grounding and logic grounding system, etc. The grounding resistance of the grounding net should be less than 1 ohm. If the grounding resistance is too large, the equipment may be damaged for a long time.

[0003] Therefore, the grounding device is quickly completed, the grounding net grounding resistance is low, the use requirements of the mobile field system equipment in "all regions, all weather, no blind spot" work are met, the personal safety and the smooth and safe equipment work are fully ensured, and the qualified grounding device has become an essential key link in the safety design of the mobile field system. Therefore, the corresponding GB / T 50311-2000 "Building and Building Group Integrated Wiring Engineering System Design Specification", GB / T 50200-2018 "Cable Television Network Engineering Design Standard", GB50116-2013 "Fire Alarm System Design Specification", "High-speed Railway Design Specification (Trial)", TB10621-2009, JGJ16-2016 "Civil Building Electrical Design Specification", 2016 "Coal Mine Safety Regulations", GB 16895.11-2001 "Building Electrical Devices Part 4: Safety Protection Chapter 44: Overvoltage Protection Section 442: Protection of Low-voltage Electrical Devices Against Temporary Overvoltage and Faults Between High-voltage Systems and Ground", and other national and industry standards and some relevant GJB provisions are intended to completely solve the grounding fault problem: the grounding net grounding resistance value is not greater than 1 ohm. Including existing military facilities, electronic microelectronic center machine rooms, especially existing mobile field special radar stations, observation and communication stations, mobile field special electronic countermeasure positions, mobile field special small area combat position command center machine rooms, and mobile field special communication equipment machine room grounding devices, etc. cannot achieve the basic requirement of less than 1 ohm grounding resistance.

[0004] The disadvantages of the mobile field special grounding device in the prior art include:

[0005] A. The current national grounding standards such as: GB / T 50311-2000 "Building and building group integrated wiring engineering system design specification", GB / T 50200-2018 "Cable television network engineering design standard", GB50116-2013 "Fire alarm system design specification", "High-speed railway design specification (trial)", TB10621-2009, JGJ16-2016 "Code for design of electrical installations in civil buildings", 2016 "Coal mine safety regulations", GB 16895.11-2001 "Electrical installations in buildings Part 4: Protection for safety Chapter 44: Protection against overvoltages Section 442: Protection of low-voltage electrical installations against temporary overvoltages and against faults between high-voltage systems and earth" and other relevant provisions of national and industry standards and some related GJBs. The specific mandatory requirements are: the grounding resistance value of the grounding grid is ≯1Ω. Including existing military facilities, electronic and microelectronic center machine room, especially existing mobile field special radar station, observation and communication station grounding device, mobile field special electronic countermeasure position grounding device, mobile field special small area combat position command center machine room grounding device, mobile field special communication equipment machine room grounding device, etc. It is impossible to achieve the basic requirement of less than 1 ohm grounding resistance, and usually only less than 4 ohm (many geological conditions in harsh areas can only be less than 10 ohm) grounding device. The failure of military facilities, equipment, computer equipment, communication equipment, electronic and microelectronic integrated equipment and accidents occur from time to time, and the probability of lightning damage increases significantly, which cannot resist meteorological disasters and equipment malfunction and accident. In the field of mobile field combat system, there are many accidents and accident hazards, especially in mountainous areas, water edges, gobi, grasslands, islands, deserts and other harsh geological conditions and lightning-prone areas.

[0006] B. The mobile field special grounding device includes: iron pick, iron shovel and hammer and other tools. Usually, multiple 1-meter-long metal (or stainless steel) steel rods are directly hammered into the ground with a hammer, and then a copper braid is mechanically connected to the multiple metal (or stainless steel) steel rods (hammered into the ground wire, and the upper end is connected by a conductor) to form a "single" ground grid. Usually, when the soil resistivity is less than 40 ohms per meter, the grounding resistance is less than 4 ohms, usually when the soil resistivity is less than 200 ohms per meter, the grounding resistance is less than 10 ohms, and usually when the soil resistivity is greater than 200 ohms per meter, the grounding resistance is less than 30 ohms. In mountainous areas, grasslands, gobi, sandy land and other places, such process makes the grounding resistance value of the grounding grid as high as hundreds of ohms, and the equipment cannot work normally, and the safety of equipment and personnel life cannot be guaranteed in rainy weather.

[0007] C. Many 1-meter-long metal (or stainless steel) steel drill rods cannot be pulled out after being directly hammered into the ground, and many phenomena such as breaking, bending and deforming, and breaking the steel drill rod after being directly hammered into the ground often occur.

[0008] D. The grounding device is basically used once and cannot be quickly replenished in continuous combat missions.

[0009] E. Poor portability, high labor hours, and many factors such as weight and material cause small combat radius and poor battlefield operability. SUMMARY

[0032] In order to facilitate the understanding of the embodiments of the present application, the following will be further explained and described with several specific embodiments as examples in combination with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present application.

[0033] The present application provides a manufacturing method of a motorized field special container grounding device, which is to solve the above key problems, i.e., to reduce the equipment failure caused by high grounding resistance of the grounding net, the equipment failure and personal safety accident caused by lightning, and to provide a good safety guarantee for the all-weather, all-area, no-blind-area and no-blind-point combat of the army. The motorized field special container grounding device has been applied in the grounding system of the high-voltage laboratory, the grounding system of the air force radar station, the grounding system of the air force airport navigation, and the grounding system of the medical site project, and the grounding resistance of the grounding net is 0.22-0.75 ohm, and some key parameters have passed the detection of the national third-party inspection and detection institution, i.e., Beijing Lightning Protection Device Test Center.

[0034] Theoretical basis of the motorized field special container grounding device:

[0035] In various grounding systems, the function of the grounding net is to provide a good ground channel for the grounding current. According to Ohm's law, the grounding resistance of the grounding net can be expressed as:

[0036]

[0037] In the formula, I is the current through the grounding grid, and U is the voltage of the grounding grid to the ground at infinity. The formula (1) is calculated to obtain a principle formula about the grounding resistance:

[0038]

[0039] In the formula, j, E and D are the current density, the electric field intensity and the electric induction (electric displacement) intensity around the grounding grid, respectively; S is the surface area of the grounding grid; ζ, ρ and C are the dielectric constant, the soil resistivity and the capacitance of the grounding grid in the soil, respectively. The formula (2) is slightly changed to become the following formula (3):

[0040]

[0041] In the formula, ρ is the soil resistivity, and C0=C / ζ is the capacitance of the cathode system of the grounding grid in the air. It is not difficult to find that the dielectric constant ζ of the soil is not in the formula. That is, the grounding resistance is irrelevant to the dielectric constant ζ of the soil. The formula (3) gives us a simple and clear grounding resistance formula from the overall understanding. It can be known that the key of the grounding resistance of the grounding grid lies in reducing the soil resistivity and increasing the capacitance value of the grounding grid.

[0042] The structure of the grounding system provided by the embodiment of the present application is shown as Figure 1 The basic components include a cathode (a motorized field special container grounding device), an anode (soil), a grounding wire and a low-resistance high-capacitance electrolyte material. The motorized field special container grounding device is fixedly arranged in a trench under the soil ground plane, the mixed liquid of the low-resistance high-capacitance electrolyte material and water is poured into the trench, and the motorized field special container grounding device is covered. The mechanical connection between the grounding plates is realized by a plurality of stainless steel hinges, and the central part of each grounding plate is electrically and softly connected by the pure copper wire woven belt. The grounding wire hole is connected to the grounding wire, and the grounding wire is connected to the load equipment on the ground.

[0046] The grounding wire hole in Figure 2 is special for the grounding wire. The grounding wire hole can be welded with a copper nose of 25-50 square millimeters of interface for a plurality of copper cables.

Figure 4 L in is the length of the grounding plate, B is the width of the grounding plate, D is the gap distance between the expanded plates of the grounding plate, and n is the number of the grounding plates.

[0050] The central part of each nickel-chromium alloy plate is electrically connected by a special pure copper wire woven belt, which has no less than 3000 wires and a cross-sectional area of > 50 mm 2 . The two sides of the pure copper wire woven belt are pressed by stainless steel special pressing strips, which have fixing holes concentric with and the same diameter as the fixing holes on the grounding plate, and can be riveted by rivets. After riveting, molecular diffusion welding is performed to electrically connect the pressing strips, the copper woven belt, and the grounding plate. The above-mentioned pure copper wire woven belt is woven by a plurality of tinned copper wires, which can be single-layer or multi-layer stacked, but the cross-sectional area is the same.

[0051] The grounding network special cathode device is usually composed of 10-70 titanium nickel-chromium grounding plates in series. The number of grounding plates determines the length of the grounding network. The grounding wire is usually led out from the central grounding plate among the plurality of grounding plates. For example, if 11 grounding plates are used, the grounding wire is led out from the 6th grounding plate. When testing the grounding resistance, the grounding resistance is the minimum value.
