[0003] The object of the present invention is to provide a power-saving device and a power-saving test method. By performing a power-saving test on the power-saving device, the power-saving device switches between the power-saving mode and the bypass mode, and the data acquisition unit collects the energy-saving The power-saving test data in the power-saving test enables the processing control unit to calculate the power-saving power of the load when the power-saving device is running based on the power-saving test data; the data acquisition unit collects the electrical parameters of the input terminal of the power-saving device at preset time intervals , when the electrical parameter change exceeds the preset threshold, a new power-saving test is carried out to adapt to the electrical parameter change caused by the load change or power supply change, which solves the problem of inaccurate test results caused by the time-varying electrical load in the prior art ; When the processing control unit receives the power-saving test data, it judges the validity of the power-saving test data. The next step is calculated only when the performance is high, which ensures the authenticity and reliability of power saving detection.

Abstract

The invention provides a power saving device and a power saving quantity test method, relating to the field of power saving quantity test. The power saving device is switched between a power saving mode and a bypass mode under control. A data acquisition unit acquires power saving test data of the power saving device in power saving test, and a processing control unit can calculate the amount of power saved by loads during operation of the power saving device based on the power saving test data. The data acquisition unit acquires the electrical parameters of the input end of the power saving device at a preset time interval. When the variation of the electrical parameters exceeds a preset threshold, new power saving test is carried out in order to adapt to the change of electrical loads. The problem that the test result is inaccurate due to the time-varying characteristic of electrical loads in the prior art is solved. The processing control unit judges the validity of the power saving test data when receiving the power saving test data. If the power saving test data does not satisfy the demand of validity, power saving test on the power saving device continues, and next-step calculation is carried out until the power saving test data satisfies the demand of validity. Therefore, the accuracy of power saving quantity detection is ensured.

Description

technical field [0001] The invention relates to the field of power saving detection, in particular to a power saving device and a power saving testing method. Background technique [0002] The operating conditions of electrical equipment vary with the process load, the actual electrical power used to do work will not remain constant, and the electrical energy consumed in the same period of time will not be equal. Conventional energy-saving tests can only be used to compare energy consumption in different time periods under different working conditions when the external work and grid power supply remain unchanged. In view of the time-varying nature of the current power load, this conventional test method is not practical. , the data tested does not have authenticity and reliability. Contents of the invention [0003] The object of the present invention is to provide a power-saving device and a power-saving test method. By performing a power-saving test on the power-saving ...
