1 Scope

GB 12668 of the provisions of this part of the electrical drive system (PDS) electromagnetic compatibility (EMC) requirements. PDS defined as 3.1 Said. Here's electrical system includes speed AC motor drives and DC motor drives. These EMC requirements for variable Stream input and/or output voltage (line voltage) rms AC 35kV below the PDS and regulations. PDS This section deals with those PDS installed in residential, commercial and industrial sites, but traction applications and electric vehicles not included Including account. PDS can be connected to industrial or public power distribution network. Industrial power grid by a dedicated power distribution transformer, the transformer is usually In or near the industrial area, and only to supply industrial users. Industrial networks can also be powered by its own power plant. In addition, PDS Can be connected directly to the public low-voltage power grid, the grid also to civilian power, when the center line is usually grounded. The relevant portion of EMC, the scope involved include different types of power from a few hundred watts to hundreds of megawatts of PDS. PDS often It included within a larger system. Content-related systems This section does not address, but provides guidance in informative appendices. Choose these requirements is to ensure that PDS residential, commercial and industrial establishments have a full electromagnetic compatibility (EMC). However, this These requirements can not include extremities may occur rarely. For PDS EMC performance due to a fault condition caused by changes Not considered. The purpose of this section is to determine its limits and test methods depending on the intended use of the PDS. This section includes the requirements for immunity and prevention Electromagnetic emissions requirements. Note 1. Electromagnetic emission may cause interference with other electronic devices (such as radio receivers, measuring and computing devices). Claim immunity is to protect equipment From continuous and transient conduction and radiation harassment (including electrostatic discharge). For anti-emission requirements and immunity requirements, it should be based on the PDS The actual environment in which balance each other. This section defines the minimum requirements for PDS EMC. Immunity requirements are based on environmental classification regulations. Anti-low-frequency emission requirements are based on the nature of the provisions of the power supply network, and anti-high-frequency hair Shoot the claim will be based on four categories of provisions intended use, both relating to the environment is also directed to put into operation. This section applies to the evaluation of the PDS. Can also be used for a separate sale of CDM or BDM (see 3.1) evaluation. This section contains. --- For the conformity assessment of products to market requirements; --- For the market before the device can not measure the high-frequency transmitter occasions (such PDS defined in 3.2.6 for the C4 category) Recommended engineering practice. Note 2. This part of the first edition (ie 2003 edition) have been identified on the intended use may require engineering design put into operation. This is done through "by Limited sales "done in the past," limited sales "is often covered by the device, in the second edition (ie edition) for Class C2 and C4 (see 3.2) are Covered. This section will serve as a complete EMC product standard, when the C1, C2 and C3 products (see 3.2.3 - 3.2.5) will be put on the market EMC product conformity assessment. As for the C4-type device only when the device is installed at a predetermined place to evaluate their radio emission. Accordingly, such equipment is Considered to be a stationary equipment. In this section 6.5 and Appendix E for this practice gives the engineering design criteria, but did not give a predetermined Defined emission limits (except in the case of complaints happen). This section does not make any safety equipment requirements for provisions, such as protection against electric shock, insulation coordination and related dielectric tests, unsafe operation, or By insecurity failure. This section does not involve electromagnetic phenomena safety and functional safety inference. In some special cases, when there are very sensitive devices in the vicinity at the time of use, it is necessary to take additional suppression measures. reducing electromagnetic emissions To below a predetermined value, or to improve the immunity of sensitive equipment. EMC standards as the PDS, this section takes precedence over other common standards, and does not require or do not require additional EMC tests. If the PDS as part of the apparatus, the apparatus also includes additional products in the EMC standards, EMC is using standard equipment package.
