27、ge 4 EN 61334-3-222001 INTRODUCTION Requirements of IEC 61 334-3-21 are applicable for phase-to-phase isolated capacitive coupling devices for power-line carrier systems on distribution line carriers (DLC). However, no international standard is available for the application of screen-to-earth intrus

28、ive inductive coupling devices. Furthermore the already standardised earthed capacitive coupling device for high voltage power-line carrier systems as described by IEC 60481 is not suitable for the application of DLC on medium voltage (MV) networks for the following reasons: - from a technical point

29、 of view, network characteristics differ considerably from HV to MV networks; - handling of HV and MV equipment requires different operational means; - from an economical point of view, the coupling device should have a price as low as possible. These considerations have led to the present standardi

30、sation of other coupling devices such as the MV phase-to-earth capacitive coupling device and the screen-to-earth intrusive inductive coupling device. Figures I and 2 show solutions for these devices. Additional solutions may become available later. As other coupling devices are standardised, new pa

31、rts to IEC 61334 will be added.

32、cable to MV phase-to-earth capacitive and screen-to-earth intrusive inductive coupling devices for medium voltage (MV) distribution line carrier (DLC) systems. Non-intrusive inductive coupling devices are not within the scope of this standard. The coupling device ensures a) the efficient transmissio

33、nlreception of carrier-frequency signals between the DLC transceiver and the power line; b) the safety of personnel and the protection of the low-voltage parts of the installation against the effects of the power-frequency voltage and transient overvoltages.

However, parties to agreements based on this part of IEC 61334 are encouraged to investigate the possibility of applying the most recent edition

36、s of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

38、ions For the purposes of this part of IEC 61334, the following definitions apply. 3.1 MV phase-to-earth coupling method method in which the coupling device is connected between the conductor of one phase of the power line and earth 3.2 MV screen-to-earth coupling method method in which the coupling

39、device is connected between the screen of the power line cable and earth NOTE Coupling may be achieved by - an intrusive coupler where a coupler is introduced between cable screen and earth, or - a non-intrusive coupler such as a split core, where the coupler is mounted around the screen of the MV c

40、able or around the earthing lead. In this latter case the screen-earth loop builds up the primary winding of a coupling transformer. 3.3 MV phase-to-phase coupling method method in which the coupling device is connected between the conductor of one phase and the conductor of another phase of the pow

41、er line isolated from the earth potential 3.4 coupling device set of capacitive coupling devices and intrusive inductive coupling devices 3.5 capacitive coupling device arrangement of elements which contributes to ensuring, together with the associated coupling capacitor, the transmission/reception,

42、 under prescribed conditions, of carrier-frequency signals between the power line and the DLC transceivers. The capacitive coupling device contributes to all or part of the functions described below (see figure 3): - tuning at the desired carrier-frequency value. This function may be performed by a

43、tuning device; - impedance matching between the power line and the DLC equipment. This function may be performed by a transformer or autotransformer; - galvanic isolation between primary and secondary section terminals of the capacitive coupling device. This function may be performed by the above-me

44、ntioned transformer if present; - draining to earth of the power-frequency current derived by the coupling capacitor. This function may be performed by an inductance, termed drain coil, or by the primary winding of the previously mentioned transformer, if present; - limitation of voltage surges comi

45、ng from the power line at the terminals of the capacitive coupling device. This function may be performed by surge arresters suitably arranged in the coupling device; - overcurrent protection at the primary terminal. This function may be performed by a fuse, which is in series with the coupling capa

46、citor. NOTE In common practice the decision on installation of a fuse often is taken by the customer, with regard to local requirements and the power line system design. Thus this decision may be a matter of explicit agreement between customer and manufacturer. O 25 October 2001 Page 7 EN 61334-3-22
