24、 of IEC 60519 is applicable to industrial high-frequency dielectric heating installations for the purpose of thermal applications such as melting, drying, welding, insect extermination and gluing of partially or non-conductive materials such as plastics, wood, rubber, textiles, glass, ceramic, paper
25、, bamboo, foodstuffs, etc. in both normal and protective atmospheres, using for example inert gases or vacuum. This standard relates to high-frequency dielectric heating installations with nominal frequency in the range from 1 MHz to 300 MHz with rated useful output power greater than 50 W. NOTE In
26、accordance with CISPR 11, there are preferred frequencies designated by the International Telecommunication Union for use as fundamental ISM frequencies. The voltage band according to IEC 60519-1 relates to the mains supply voltage. In some circuits of the dielectric heating installation, the d.c.,
27、a.c. or radio-frequency voltages can have greater values (e.g. in the generator due to a built-in transformer). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition citied applies. For undated referen
28、ces, the latest edition of the referenced document (including any amendments) applies.

32、cy; b) the rectifier part which generally contains the components for the conversion of mains frequency supply current into high voltage d.c.; c) the oscillator part, which contains the components necessary for the generation and matching of high-frequency energy (the oscillator part is placed in a
33、shielded enclosure to reduce high-frequency radiation); d) the control and monitoring system, which contains the programmed control with interlocks and safety devices for overload protection, as well as switchgear and monitoring devices. 4.2 Protection against direct contact 4.2.1 General All live p
34、arts other than the output terminals of the dielectric heating generator shall be located in one or more enclosures with adequate protection against direct contact. 4.2.2 Means of access to parts under voltage band 2 Doors and/or detachable panels giving access to voltages band 2 (up to 1 000 V a.c.
35、 or 1 500 V smooth d.c.) shall be provided either with door locks, which can be opened only by the use of a key, or with electrical interlocks that disconnect the voltage when the door is being opened or the panel is being removed. Detachable panels which are intended to be removed only very occasio

Hatches in the protective enclosures or movable parts of the protective enclosures shall have positively operated non-resettable safety switches or a non-resettable interlock so arranged that the h
40、igh-frequency voltage cannot be applied except when entry does not allow contact between the high-frequency parts and the hatch cover of the protective enclosure, or when the protective enclosure effectively provides complete protection. Detachable panels which are intended to be removed only very o
41、ccasionally shall be fastened with safety screws which cannot be removed by the use of a standard tool or without the use of any tool. 4.2.5 Warning plates Necessary warning plates shall be provided.

45、l be in accordance with IEC 60519-1. The parts of the equipment carrying high frequency power are to be protected to ensure an admissible touch voltage at the operators position, for example by a protective earthed screen and/or earthing at the operators position. 7 EN 60519-9:2005 4.4 Temperature r
46、ise Protection against fire 4.4.1 In dielectric heating generator circuits and in rectifiers the electrical circuits shall be arranged so that they are not submitted to excessive temperature rises, nor should they produce a temperature rise in the enclosure in excess of the levels normally permitted
47、 for installations of electrical equipment. 4.4.2 Materials used in a compartment containing high-frequency voltages shall not be of a type allowing any sustained burning. 4.4.3 In the case where a fault in the cooling circuit is liable to cause a temperature rise inside the generator in excess of t
