According to foreign media reports, the most comprehensive study to date on electromagnetic safety of electric vehicles shows that the electromagnetic field strength of electric vehicles is far lower than the safety exposure level specified by the International Commission on Non-Ionizing Radiation Protection.
The electromagnetic safety research project, funded by the European Union and involving seven scientists, believes that drivers and passengers in electric vehicles are as safe as those driving or riding hydrogen, gasoline or diesel-powered cars. No electric car exposes the occupants to electromagnetic fields that are above international safety standards. The researchers say that in fact, these magnetic fields are much lower than the recommended values.
The Norwegian Institute of Science and Technology, the largest independent research institution in Scandinavia, led and participated in the study. Kari Schjlberg-Henriksen, a physicist at the institute, said: "The impact of magnetic field exposure is of public concern. This topic often appears in the media. As the number of electric vehicles continues to increase, the significance of this project is very significant."
The goal of the research project is to establish a standardized method for measuring the electromagnetic field of electric vehicles and increasing public confidence in the safety of electric vehicles.
Acceptable safety limits for exposure to magnetic fields of different frequencies were developed by the International Commission on Non-Ionizing Radiation Protection. The researchers used eight different electric vehicles, including pure electric vehicles, hybrid vehicles, plug-in hybrid vehicles and fuel cell vehicles, as well as two traditional gasoline vehicles and one diesel vehicle to study these vehicles. The level of the magnetic field within it is determined to determine if its intensity is close to the recommended human exposure limit; and a mannequin with a sensor on the head, chest and foot is used to obtain standard, comparable measurements.
They used real cars to measure both in the laboratory and in road tests. It was found that the highest value of the electric field of the electric vehicle appeared near the floor, around the battery itself and when the vehicle was started. In either case, the intensity of the magnetic field exposed to the electric vehicle is less than 20% of the recommended safety limit of the International Commission on Non-Ionizing Radiation Protection. The measurements obtained at the head are both below 2% of the limit.
The magnetic field strength measured in gasoline and diesel vehicles is about 10% of the limit. This shows that there is little difference between electric vehicles and gasoline and diesel vehicles.
Scientists believe that the electric field of electric vehicles is far below the limit and is within a safe enough range.
Belt Conveyor
The belt conveyor has the advantages of large conveying capacity, simple structure, convenient maintenance, etc., and the cost performance is high.
The belt conveyor line transports smoothly and can be customized according to customer requirements, and there are a variety of belts to choose from (PVC anti-static rubber, rubber belt, food special belt, etc.).
The belt conveyor has various structures, which can be divided into groove belt conveyor, horizontal belt conveyor, climbing belt conveyor and other forms. The conveyor belt can also be equipped with lifting baffles, skirts and other accessories to meet various processes. It is required that both sides of the conveyor are equipped with worktables and light stands, which can be used as assembly lines for electronic instrument assembly and food packaging.
According to the requirements of the conveying process, it can be conveyed by a single unit, or composed of multiple units or combined with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of different layout types of operation lines.
The belt conveyor is mainly composed of a frame, a conveyor belt, a belt roller, a tensioning device, and a transmission device.
The support structure adopts steel structure and aluminum structure; the workbench can be selected according to customer needs, mainly including aircraft platform, independent workbench, and long workbench; belt running speed can be set by itself, constant speed, electromagnetic speed control, frequency conversion speed control .
Belt conveyors are widely used in electronics, plastics, chemicals, food and other industries.
