Facing in the development of society, in the progress of science and technology, the development of the society environment, the production development of the enterprise must also follow the pace of The Times. Now, the use of numerical control woodworking machinery is very common, in order to make better use of numerical control woodworking machinery, here to introduce the numerical control woodworking machinery of lightning protection engineering. 1. Nc equipment direct lightning lightning contains a great deal of energy, peak voltage is 5000 kv lightning defined, has a great damage. Form the following three effects: ( 1) Infinite rich current flow within few microseconds moment, make the earth potential agile up high, form a counterattack, damage to the personal and equipment safety. ( 2) Strong electromagnetic wave, lightning current attack on the power cord and signal induction high pulse voltage. ( 3) Lightning current flows through the extremely high quantity of heat, electrical equipment attack form fire or blasting disturbance. 2. Nc equipment lightning of the thunder in the distance of lines or due to a high voltage for electromagnetic induction, the outdoor power supply circuit and communication circuit to electrical equipment within the building indoor. 3. Induction thunder clouds discharge frequently attack between strong electromagnetic wave leads to common mode and differential mode, affect electric equipment operation. The above to introduce about numerical control woodworking machinery of lightning protection engineering analysis, hope to have some help to you.
