1 Scope and purpose

GB/T 10066 provisions of this part of the high-frequency induction heating device generator output power measurement method.

This section applies to the high-frequency generator and inductor and hold the charge required by the mechanical equipment (such as quenching machine) composition, the frequency Range up to 300MHz, power is equal to and greater than 500W Heating (such as surface (or local) quenching and diathermy, welding, brazing, melting, forging Manufacturing, semiconductor refining, etc.) industrial RF or high frequency induction heating device.

The load described in this section can be used for EMC compliance CISPR11 assessment.

This section relates to the power generator rated at continuous operation under the conditions specified by the manufacturer.

The method for measuring the output power of a generator running in a short-pulse cycle (for example, using an adiabatic calorimeter) thinking.

Care must be taken when using electronic systems for power measurements because their accuracy can not be guaranteed, especially at higher frequencies. These ones the instrument requires a large current transformer and a voltage transformer when measuring the output power. These transformers also have errors at higher frequencies. These measurements Quantitative methods require specialized knowledge to be applied correctly and are therefore not described in detail in this section.

3 Terms and definitions

The GB/T 2900, GB 5959.1-2005 and GB 5959.3 established and the following terms and definitions apply to this section.

At the generator power output, enter the power of the test load specified in this standard.

Note. This definition is explained by Figure 1. To the left of the graph is the generator and bounded by its two output terminals. The load is connected to these two output terminals. Outside the generator cabinet all the power shown is defined as the generator's output power. It includes power consumed in inductors, power leads and calorimeters.

For the measurement of high-frequency power by the water-cooled components of the device, the flow of cooling water is controlled, the temperature difference between incoming and outgoing water is monitored.

Note. The water-cooled parts made of steel or other conductive materials, high-frequency current is induced in it.
