Problems solved by technology

[0002] The portable power quality analyzer can analyze all power quality parameters such as voltage, current, harmonics, fluctuations, sags, flicker, three-phase unbalance, frequency, etc. of the power supply line. It has Ethernet, input contacts, output contacts, USB and other communication interfaces, which can be used for network communication flexibly. At the same time, it has the advantage of small size and can be carried around more conveniently. It is difficult to adjust the angle of the power quality analyzer itself, which limits the viewing angle of the data when the operator is measuring. At the same time, the portable power quality analyzer needs to be connected to an external measurement connector. One end of the measurement connector is connected to an electric line, which is easy to be pulled , causing the measurement connector to fall off from the power quality analyzer, resulting in interruption of measurement data

Abstract

The invention discloses a portable electric energy quality analyzer which structurally comprises an analyzer, an adjusting mechanism, a display panel and a button, the top of the analyzer is fixed to the upper end of the adjusting mechanism, the display panel is embedded in the surface of the front end of the analyzer and elastically rotates around a torsion shaft through a top plate mechanism, and the lower end of a fixed pipe sleeve rotates around a rotating shaft. The angle between a clamping piece and the top of a telescopic rod is rotated through a rotating ball, the clamping piece is clamped into a groove in a clamping plate, multi-angle adjustment is conducted between a supporting vertical plate and the analyzer, the visual angle of data observation of an operator in the measurement process is increased, and the measurement accuracy is improved. In the measuring process, one end of an external measuring connector needs to be inserted into the insertion mechanism, the outer side of the measuring connector abuts against the buckling piece, at the moment, the jacking spring exerts reverse elastic force, the measuring connector is elastically and tightly buckled through the buckling piece, the firmness of the measuring connector inserted into the connector pipe is improved, and the measuring precision is improved. And the conduction stability of measured data is improved.

Description

Technical field [0001] The present invention relates to the field of power measurement, and more particularly, more particularly to a portable power quality analyzer. Background technique [0002] The portable power quality analyzer analyzes the voltage, current, harmonics, fluctuations, temporary reduction, flash, three-phase imbalance, frequency, etc., with Ethernet, open contact, open contact, USB The various communication interfaces, can be flexible to communicate, while having a small size, it can carry more convenient portable, but due to the smaller volume of the portable power quality analyzer itself, the portable The power quality analyzer itself is difficult to conduct angular adjustment placed, resulting in limitation on the observation angle of the data while performing measurement, and the portable power quality analyzer needs to connect the external measurement joint, measure the first end of the joint, which is easy to pull , Resulting in the measurement joint from...
