Embodiment 2

[0096] This embodiment is optimized on the basis of Embodiment 1, and the performance testing method uses a performance testing system to collect, analyze, process and display data.

[0097] The data that needs to be collected in the performance test method are:

[0098] Water mass of water load M W , in step S1, the mass of the water load is calculated after the volume is measured by measuring tools such as a measuring cylinder, or the mass of the water load placed in the microwave heating cavity is directly weighed;

[0099] Initial water temperature T1, in step S1, directly measure the initial temperature of the water load through elements such as a thermometer or a temperature sensor;

[0100] To test the water temperature T2, in step S2, directly measure the temperature of the water load when testing the performance of the microwave system through elements such as a thermometer or a temperature sensor;

[0101] The starting time time1 of the magnetron starting to work, ...

Embodiment 3

[0142] In this example, on the basis of Example 1 or 2, three loads are prepared according to the mass ratio of 0.5N:1N:1.5N to test the performance of the microwave heating device. Where N is the number of magnetrons working in the corresponding microwave heating device.

[0143] For example: there are 9 working magnetrons in the microwave heating device, that is, when N=9, the masses of the three water loads are 4.5KG, 9.0KG and 13.5KG respectively.

[0144] Another example: there are 10 working magnetrons in the microwave heating device, that is, when N=10, the masses of the three water loads are 5.0KG, 10.0KG, and 15.0KG respectively.

Description

technical field [0001] The invention relates to the field of microwave system testing, in particular to a performance testing system and testing method of a multi-magnetron microwave heating device. Background technique [0002] Multi-magnetron microwave heating device, also known as multi-feeder microwave heating system, uses multiple magnetrons, each magnetron is connected to an exciter, and each exciter is connected to the microwave heating cavity through waveguide distribution. The feed port transmits the microwave energy to the microwave heating cavity, heats the carrier material in the microwave heating cavity, and feeds energy to the load. [0003] Compared with the single magnetron microwave heating system, the structure and control of the multi-magnetron microwave heating system are slightly more complicated, but because the microwave power of each magnetron corresponding channel is not high, it is required that the product has high-power microwave heating performan...
