Cold and hot shock test boxErrors in the power supply will directly affect the processing during the experiment, as the power supply is like the blood in the human body, and the blood circulation can only be refreshed due to metabolic reasons. However, when the power supply is working in the test box, when the cold and heavy machine is driven, it is the state of awesome. However, how to save in the event of an error?

Inspection method: 1. Is the displayed part of the three-phase power supply phase sequence error fault in the red indicator light on without flashing?

2、 Is the displayed part of the three-phase power supply phase sequence error fault indicated by a flashing red indicator light?

Solution: 1Cold and hot shock test boxFor this situation, it usually occurs when the equipment is repositioned or moved, and two of the three lines of the three-phase power supply can be swapped, because reversing the phase will cause the motor to run in reverse.

2、 Please check or inquire with the power supplier if there is a three-phase power supply under phase condition, and if one of the three lines of the three-phase power supply is not receiving power; Because if an under phase condition occurs, it will cause the motor and compressor to burn out due to excessive operating current.

During work,Cold and hot shock test boxThe accuracy of the test results is often determined by small details, such as the presence or absence of problems with the testing equipment. In the experiment, the repeated impact ability of various materials on their high and low temperatures can be measured, and the quality problems of the products that can be detected can be identified.
