Foreword

This standard replaces GB/T 13032-1991 "marine diesel generator sets." This standard compared with GB/T 13032-1991, the main technical content of the following changes.

a) on marine diesel generator set voltage level and power has been extended;

b) an increase in start-up mode "manual start" mode;

c) the environmental conditions specified in the corresponding increase in pitching;

d) the steady-state voltage regulation rate increase "in power factor 0.8 (lag) when" a prerequisite;

e) an increase of the transient droop on stage loading of content;

f) enrich the marine diesel generator set vibration and noise reduction part of the contents;

g) fulfilling the relevant test content. The standard proposed by China Shipbuilding Industry Corporation. The standard by the China Machinery Standardization Technical Committee of Marine Diesel Engine Technical Committee. This standard was drafted. China Shipbuilding Industry Corporation seventh - four Institute. The main drafters of this standard. He Yanbo, Zhongru Sen, Xie Jianping. This standard replaces the standards previously issued as follows:

--- GB/T 13032-1991. Marine diesel generator sets

1 Scope

GB/T 13032-2010 is the Chinese national standard on marine diesel generator set, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 9 August 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2010. Classification: ICS 47.020.60, CCS U61. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the marine diesel generator sets (hereinafter referred to as "units") terms, product classifications, requirements, test methods, inspection rules, The scope of supply and so on. This standard applies to the ship's main power supply and emergency power supply unit, does not apply to shaft generator, frequency, and dual-phase AC power frequency Output units.
