Lightning performance

(Summary description)A,andonanti-mineproductspiecesshouldhasofperformance,IEC,IEEEandChinarelatedstandardorganizationareinlowvoltagedistributionsystemofanti-mineproductsrelatedstandardintheproposedhasperformancerequiremen

Information
A, and on anti-mine products pieces should has of performance, IEC, IEEE and China related standard organization are in low voltage distribution system of anti-mine products related standard in the proposed has performance requirements and test method. on anti-mine products products of classification impact test, domestic usually only minority anti-mine products test center has test capacity, for most anti-mine products check side institutions for should according to products of nominal parameter view anti-mine engineering in the anti-mine products of select and using whether reasonable.
 
Second, signal lightning tests there are generally two ways:
 
(1) generally test your line, if necessary, to the line between test. multi-channel input/output lightning products randomly selected a test circuit.
 
(2) nominal tolerance of 8/20 us current wave-shaped lightning products lose those end, positive and negative polarity 5 times each, each impact interval for 3 min, residual pressure at the output side Ures, and the residual pressure value is only used to show that
 
10 shocks to protect stability, without the wave mutation, high and low residual voltage instability, and so on, can be used to determine the voltage protection level.
