1 Scope and purpose

GB/T 10066 provisions of this part of the determination of the high-frequency dielectric heating apparatus of power output.

This section applies to the natural ambience and atmosphere (for example, an inert gas or vacuum), for such as plastic, wood, rubber, textiles, glass Glass, ceramics, paper, bamboo and food portion of the conductive or non-conductive material is melted, drying, heat sealing, bonding and other pest control and thermal processing industries High-frequency dielectric heating apparatus.

This section refers to the nominal frequency of 1MHz ~ 300MHz, Useful rated output power greater than 50W of high-frequency dielectric heating apparatus.

The main purpose of this section at the time of the electric power supply test, facilitate their compliance with the provisions of 6.4 GB 5959.9-2008 to begging. It basically does not make some kind of high-frequency heating may be applied to meet the user's requirements. Dielectric heating applications is very wide, so these tests any output power is always obtained value should not be used to represent a specific dielectric heating apparatus capable of power consumed, but in some cases, the output value will be used to represent the performance of the device.

For example, the structure of the power required for the furnace and its feed material, the heating temperature, humidity and the relevant electrode systems.

Note. When heating the dielectric parameters over time and/or temperature changes significantly charge, the actual output power values \u200b\u200bobtained with the standard test strip Different values \u200b\u200bobtained pieces.

Means the specified band for working in the International Telecommunication Union (ITU), the frequency of the generator is to follow the output circuit of the resonant frequency, which Thus, the output power even in the case of manual tuning of the output circuit, to remain fairly stable in the working cycle. Therefore, in accordance with this section, Test well shows under actual operating conditions of real output power.

Within a specified frequency band of the device working in the International Telecommunication Union (ITU), the frequency generator remained stable, but the resonant frequency of the output circuit it varies with the load change media parameters. Therefore, the value of the average output power than in the work cycle under the test conditions of low to obtain many. The value depends on the time automatic tuning system response.

This section applies to equipment under normal rated conditions of continuous operation.
