GB/T 7417-2010AX series relays for railway signaling (English PDF)

Foreword

This standard replaces GB/T 7417-2001 "AX series relays." This standard compared with GB/T 7417-2001, major changes as follows.

--- Increased JZXC-1616 the technical indicators of the relay, remove JWXC-7, JWXC-2000, JZXC-H156, JYJXC-J3000 and JDBXC-550550 the technical indicators are five models of the relay (2001 version 3.1,3.2.1,3.4, 4.7,4.9,4.24,5.3, A1.2, A1.3, A2, A3, Excerpts 3.1,3.2.1,3.4,4.7,4.9,4.24,5.3, A.1.2, A.2, A.3);

--- Revised JWXC-H310 relay ambient temperature (version 2001 4.3a), 4.19, this edition 4.3a), 4.19);

--- Increased housing requirements and test methods relay the flame retardancy (Excerpts 4.4b), 5.4);

--- Removes the requirement galvanized surface passivation film (2001 version 4.6.1);

--- Amendment Qi requirement ordinary contacts and strengthen contacts between the (2001 version 4.8, this version 4.8);

--- Revised magnetization value JWXC-H310 relay and JWJXC-H 800.06 Release value relay current ring (2001 edition 4.9, this version 4.9);

--- Increased rectification, polarizing, and there are very ordinary contacts relay electrical life times; there are increased electric pole relay switch after life becomes extreme value of range; revised after the relay electrical life of the contacts of the contact resistance variation range; revised JYJXC-X135220 Relay contacts Inductance value of the load; revised test methods for electrical life test (version 2001 4.24,5.6, this edition 4.24,5.6);

--- Increased rectification, polarizing, a very ordinary relay contacts and strengthen Promise, a great strengthening of the relay contacts mechanical life times; increase Plus range have extremely relay mechanical life after transfection extremes; revised test methods - Mechanical Life Testing (2001 edition 4.25,5.7, this edition 4.25,5.7);

--- Amendments to the socket insertion force requirements (Edition 2001 4.26,4.27, 4.26,4.27 this edition);

--- Increased testing methods Promise relay magnetic circuit air gap (edition 5.5).
