such lightning protection devices not only cannot protect against lightning, but also aggravate the potential danger of lightning hazards. Secondly, during the maintenance, reconstruction and decoration of buildings, some units and construction personnel do not pay attention to the protection of their lightning strip (), resulting in artificial damage, and some inadvertently cut off the grounding device during construction, resulting in the breakage of the downlead, which will bring hidden dangers of lightning protection safety. Thirdly, some units have a weak awareness of lightning protection safety, do not understand the performance of lightning protection devices, and randomly pull and connect other electrical lines on lightning protection devices. These electrical lines often become the "culprit" of various electronic equipment in buildings suffering from inductive lightning strikes. In addition, the lightning protection measures inside the building are mainly the lightning protection devices used for the prevention of induction lightning of various electronic and electrical equipment. Because the materials used are mainly zinc oxide varistor elements and other electronic components, these lightning protection devices have significantly reduced or degraded after being subjected to one or more repeated lightning strikes, so they should also be checked regularly. Problems are found through inspection, so that they can be repaired or replaced in time. Some inflammable and explosive places such as petroleum and chemical industry, as well as densely populated public places such as enterprise computer systems and schools, should regularly hire institutions with testing qualifications to carry out testing, so as to ensure the normal use of lightning protection devices and take precautions. The meteorological authorities of provinces, autonomous regions and municipalities directly under the central government are responsible for the management of professional qualifications of lightning protection projects in their respective regions, and for the identification of professional design and construction qualifications of class B and class C lightning protection projects. Article 4 a class a qualification unit may be engaged in the design or construction of class I, class III lightning protection buildings (structures) and structures as well as lightning protection projects, renovation projects and new lightning protection projects in dangerous environments such as oil depots, gas depots, refueling and gas stations, liquefied natural gas, oil (gas) pipeline stations, valve chambers, etc. specified in the code for design of lightning protection of buildings. Class B qualification units can be engaged in the design or construction of lightning protection projects, rectification projects and new lightning protection projects of class III lightning protection buildings (structures) specified in the code for design of lightning protection of buildings. Class C qualification units can be engaged in the design or construction of lightning protection works, rectification works and new lightning protection works of class III lightning protection buildings (structures) specified by the project manager he Hongwei in the code for design of lightning protection of buildings. The design or construction of protection units and other immovable lightning protection projects must be undertaken by units with Class A and class B qualifications

with the arrival of thunderstorm weather, recently, Baotou electric service section of Hohhot Railway Bureau has strengthened the regulation of lightning damage. Starting from standardizing lightning protection inspection and regulation, strengthening personnel training, and improving the handling of lightning damage emergency faults, it has taken measures such as guarantee inspection before thunderstorm, key monitoring during thunderstorm, comprehensive re inspection after thunderstorm, and technical stationing, so as to solidly do a good job in lightning protection of signal equipment and facilities and support a "protective umbrella" for safe railway transportation

establish a level by level responsibility system for lightning protection, establish a standing book for lightning protection equipment and facilities, and accurately record the installation location, starting time, model, quantity, testing time, etc. of lightning protection equipment and facilities. Regularly conduct comprehensive inspection and testing of lightning protection components and ground wires, establish a cancellation table for existing problems such as defects of lightning protection components and poor lightning protection ground wires, and formulate remediation measures. Lightning protection detection company

"professional design" upright lightning rod or "reliable grounding" for the camera upright rod next to the lightning rod. Considering the "lightning strike ground potential result", it is not only impossible to achieve zero potential and equipotential ", but also possible to" ignite ". The external lightning arrester refers to the SPD installed on the power supply line and signal line, and the built-in lightning arrester refers to the lightning protection components or lightning protection modules integrated in the equipment. At present, there are relatively few mature products of built-in lightning arresters, which are generally installed on the road board, such as discharge tubes, TVs, etc. The external lightning arrester is usually designed, produced and sold by professional lightning protection manufacturers, which has the advantages of good lightning protection effect and convenient replacement. The built-in wide sample fixture lightning arrester is usually designed, produced and sold by the security equipment manufacturers, which has the advantage of low cost. However, once the built-in lightning protection module is damaged, the security equipment needs to be repaired or replaced, which is difficult to be accepted by users. Built in lightning arrester or built-in surge proof module. The built-in anti surge module corresponds to the product test standard of iec61000. Therefore,

for the electric lightning rod produced by the company, the total turnover of lightning protection projects shall not be less than 4 million yuan, and the turnover of at least two lightning protection projects shall not be less than 500000 yuan; (4) The lightning protection works undertaken must be subject to the design review and completion acceptance of the local meteorological authority; (5) It has obtained grade C qualification and has passed the annual inspection for the past three years. Article 11 in addition to meeting the basic conditions of Article 8, an entity applying for Grade C qualification shall also meet the following conditions: (1) more than 500000 yuan; (2) More than one senior technician in lightning protection related disciplines, more than three intermediate technicians, and a certain number of auxiliary technicians. Chapter III qualification application and acceptance Article 12 units applying for class a qualification shall apply to the competent meteorological department of the province, autonomous region or municipality directly under the central government where the enterprise is registered; Units applying for class B and class C qualifications shall apply to the competent meteorological authority at the municipal level divided into districts where the enterprise is registered. The acceptance time of class a qualification is September every year, and the acceptance time of class B qualification is March and November every year
