Introduction

The purpose of this standard is to establish a basic test specifications to assess industrial machinery and electrical equipment suffer from power lines and interconnect lines When high-energy performance harassment. This standard electrical industrial machinery, electronic equipment and control systems by the transient overvoltage caused by lightning and switching unipolar waves Chung (impact) immunity test basic requirements, configuration and test equipment, test methods and procedures and with different environmental and installation conditions associated Test level. The reference to the standards GB 5226.1-2002/60204-1 IEC .2000 "Part 1 Safety of machinery - Electrical equipment Score. General technical conditions ", GB/T 21067-2007" industrial machinery and electrical equipment Electromagnetic compatibility - Generic immunity requirements "and other standards. Industrial machinery and electrical equipment Surge immunity test specification

1 Scope

This standard specifies the electrical machinery industry, electronic equipment and systems (hereinafter referred to simply as "Device") to switch over from the lightning and electrical transients Pressure-induced unipolar surge (impact) Basic immunity test requirements, test equipment and configuration, test methods and procedures, test result evaluation And preparation of test reports, and also provides a different environment and installation conditions associated preference test level. This standard applies to rated voltage not exceeding AC1000V, DC1500V, does not exceed the rated frequency of 200Hz electrical industrial machinery Gas, electronic equipment and systems surge or electrical equipment and components of the system (impact) immunity tests. NOTE. This standard does not high voltage insulation capability of the test, do not consider direct mine. Immunity test is applicable to the device. --- R & D testing; --- Type tests; --- Acceptance test; --- Production test.
