GB / T 12668.1 2002: This section is the GB 12668 "speed electrical power drive," the first part, given low voltage direct current electric transmission system speed rating requirements. For general purpose DC speed drive, including power converters, control equipment and one or several motors, do not apply to traction drive transmission and electric vehicles. This part of the converter is given the characteristics of their relationship with the DC drive, and indicate on the converter rating, normal use conditions, overload conditions, surge withstand capabilities, stability, protection, AC power ground performance requirements and tests, In addition, the standard also addresses issues such as control programs, diagnosis and topology of the Application Guide.
This part identical with IEC 61800-1 1997, in the technical content and the preparation of the format exactly.
GB/T12668.2 2002: This section is the GB 12668 "speed electrical power drive," the second part of the low voltage AC variable frequency electric drive system is given rating requirements. For general purpose AC variable speed drive system, from electrical equipment (including the converter section, motors and other equipment, but not limited to feed part), and control devices (including switch control - such as on / off control, voltage , frequency or current control, trigger system, protection, condition monitoring, communication, testing, diagnosis, production process interface / port, etc.) form a system. This standard does not apply to traction drive and electric drive vehicles; apply the following to connect the AC power voltage 1kV, 50Hz or 60Hz, the load side frequency up to 600Hz of the electric transmission system. This standard is given on the inverter rating, normal use conditions, overload conditions, surge withstand capabilities, stability, protection, grounding and testing of AC power such as performance requirements.
This part identical with IEC 61800-2 1998, in the technical content and the preparation of the format exactly.
GB12668.3 2003: This section is the GB 12668 "speed electrical power drive," the third part, given EMC product standard and the specific experimental methods. Provides electric transmission system (PDS) of the electromagnetic compatibility (EMC) requirements, including the speed of AC motor drive and DC motor drives, especially as installed in the industrial environment and civil environment, PDS, also does not include traction applications and electric vehicles. In which the interference PDS - immunity requirements and the minimum security requirements of Quality Supervision, Inspection and Quarantine which are mandatory, the rest of the recommended requirements.
This part identical with IEC 61800-3 1996, in the technical content and the preparation of the format exactly.
GB / T 12668.4 2004: This section is the GB 12668 "speed electrical power drive," the fourth part, 1000V AC voltage is given more but not exceeding 35kV AC electric transmission system speed rating requirements. Applicable, including power converter equipment, AC motor control equipment and speed electrical drive system, but does not include traction drive transmission and electric vehicles. For voltages above 1kV used with low-voltage converter (less than 1Kv) input connected to step-down transformer and / or boost the output transformer of the electric transmission system, applicable to GB / T 12668.2. This part of the characteristics of the converter, and the communication topology and the relationship between the electric transmission system are illustrated, and also provides information on rating, normal use conditions, overload conditions, surge withstand capabilities, stability, protection, AC power grounding, topology and other performance requirements and testing. In addition, this section also gives the program, such as control, torsional vibration analysis of the application guidelines and integrated electric drive system components recommended method.
This part identical with IEC 61800-4 2002, in the technical content and the preparation of the format exactly.
GB 12668.5: give and electrical, thermal, and other functions related to security requirements. Applicable, including power converter equipment, transmission equipment and motor speed control electric transmission system. But does not include traction drives and electric vehicle transmission; applied to connect the AC power supply 1 kV the following, 50 Hz or 60 Hz DC transmission and converter input or output voltage of 35 kV the following, 50 Hz or 60 Hz of AC drive . Provides for the speed electrical power drive or the components related to electrical, thermal and energy safety requirements. This standard, you can refer to parts within the meaning of the energy risk explosion or capacitor energy storage. Apart from interface requirements, this part of the transmission equipment is not covered.
This part of the same with IEC61800-5-1.
GB 12668.6: given load operation with rated current forms of measurement and the corresponding lead responsibility. This section speed electrical drive system (PDS) rating requirements, the basic transmission mode (BDM) rating of the requirements to provide alternative methods. For DC, AC PDS system rating has been given 12668.1 and 2668.2, there can also be viewed as a complement 12668.1 and 2668.2. For all converters, whether with or without transformers, should be selected among the following six work load to the provisions of a rating, or even the work of the system load, intermittent work system peak load, intermittent work load system, free set time interval intermittent work load system, repetitive work load system, the system of non-repetitive work load. The transmission speed for the load current - time curve although complicated, but usually able to determine the most suitable basis for the load rated current work system.
This part of the same with IEC61800-6.
The Chinese national standard-setting speed electrical power drive began in 2000, the Standardization Committee commissioned by the National Standardization Committee was established, all known as the "National Power Electronics speed electrical power drive semiconductor power converters Standardization Technical Committee", the secretariat affiliated to Tianjin Electric Drive Design Institute, responsible for national speed electric drive system technology in the field of standardization of technical work involving the main products are AC and DC electrical transmission equipment. 6 have been developed electric drive speed control system of the national and industry standards: GB / T 3886.1-2001, JB / T 10251-2001, GB / T 12668.1-2002, GB / T 12668.2-2002, GB 12668.3-2003, GB / T 12668.4. One GB / T 12668.1-2002, GB / T 12668.2-2002, GB 12668.3-2003 formally approved and promulgated by the Bureau of Technical Supervision; GB / T 12668.4 pending in the reported period; GB 12668.5, GB 12668.6 clean up the old as the State Committee for Standardization to declare a temporary extension of the standard work is expected to be reported in January 2005 pending.
In the twelfth national electrical automation and electronic control system of academic annual meeting of the national standards were Publicizing inverter. National standards converter is entirely transformed from the IEC 61800 standard, has been formally adopted and published in the standard (GB / T 12668.1-2002, GB / T 12668.2-2002, GB 12668.3-2003) and report the pending standard (GB / T 12668.4), unless the GB 12668-3 (electromagnetic compatibility standards) of PDS's interference - immunity requirements and the minimum safety requirements, other standards are recommended, which, inverter manufacturers mixed response.
