Foreword
This standard and the International Telecommunication Union ITU-TK. Recommendation 12 "telecommunication device protection with gas discharge characteristics" (2006) a
Consistency is not equivalent and according to the development of communication technology, improve production technology and the actual needs of the discharge tube, and a certain amount of supplementary
And improve so that the standard scientific, better operability and practicality.
This standard replaces GB/T 9043-1999 "communication device over-voltage protection General technical requirements of gas discharge tubes."
This standard and GB/T 9043-1999 main technical differences are as follows.
--- The gas discharge tube of nominal DC breakdown voltage division finer categories (see Table 1).
--- Increase the breakdown voltage of the low-impact category breakdown voltage of the gas discharge tube (see Table 2).
--- Modify the breakdown voltage of the conformity assessment method (see Table 3).
--- Increased life test test levels, and increases the test categories (see Table 4).
--- Clear capacitive test test voltage (see 6.5).
--- Increasing the discharge power voltage range and resistance to flow test recommended program (see Appendix B).
Appendix A of this standard is a normative appendix, Appendix B is an informative annex.
The standard proposed by the People's Republic of China Ministry of Information Industry.
The standard by the China Communications Standards Association.
The standard by the China Telecommunications Corporation (Guangzhou Research Institute), an electronic EPCOS (Xiaogan) Co., Ltd., the Ministry of Information Industry and Telecommunications Research Institute
