Description

Electric energy quality interference source tolerance testing device Technical Field The utility model belongs to the technical field of storage cabinets, and particularly relates to a device for testing tolerance of an electric energy quality interference source. Background A power quality interference source tolerance test device is a device for evaluating the tolerance of an electrical device or system in the face of various power quality interference sources. The common power quality interference source tolerance test device is a power quality analyzer. The electric energy quality analyzer can detect various electric energy quality parameters such as voltage, current, frequency, harmonic voltage content, three-phase voltage unbalance degree and the like. The method can accurately measure the electric parameters, display the vector diagram of the measured voltage and current, and analyze whether the wiring of the metering equipment is correct. The ac power quality from the utility grid to the customer premises can be measured and analyzed, including frequency deviation, voltage fluctuation, flicker, three-phase voltage allowable unbalance, grid harmonics, and the like. When the power quality analyzer is not in use, the equipment and the data detection line are separated, which leads to the data interface of the power quality analyzer being exposed. The long-term exposure of the data interface can lead to the surface oxidation of the data interface and the increase of contact resistance, so that the signal attenuation is serious during data transmission, the problems of data loss, error code and the like occur, and the accurate measurement and analysis of the data by the power quality analyzer are further affected. Meanwhile, impurities such as dust easily enter the exposed data interface, are accumulated inside the interface, so that the appearance of the interface is neat, good contact between the interface and a cable is prevented, and poor contact is caused. To this end, the utility model provides a device for testing the tolerance of a power quality interference source. Disclosure of utility model In order to overcome the deficiencies of the prior art, at least one technical problem presented in the background art is solved.
