The invention provides a mobile sectionalized meter comprising an open current transformer, an insulting electric clip and an electric energy meter. The open current transformer and the insulting electric clip are connected with the electric energy meter. One end of a secondary winding wound on the secondary iron core of the open current transformer is provided with a connecting end, and the other end is externally connected with three connecting ends which are corresponding to three sets of winding turns. The three connecting ends are correspondingly connected with the current detection access ports of three gears on the electric energy meter. The meter box of the electric energy meter is fixed on an electric pole through a clamping device. Compared with the meters in the prior art, the beneficial effects of the mobile sectionalized meter are that acquisition of current information of multiple sets of gears can be realized by the mobile sectionalized meter, the mobile sectionalized meter is suitable for power load of different capacitates and the magnification ratio of different gears is selected for different current acquisition values so that the measurement accuracy is high, the range of application is wide, installation and detachment of the electric energy meter box and the transformer are quite convenient and implementation of high-altitude work is facilitated.
Description
technical field [0001] The invention relates to the measurement and collection technology of power supply information, and in particular designs a mobile section meter. Background technique [0002] At present, the State Grid Corporation is promoting line loss synchronization work. The low-voltage station area within the company only installs an assessment meter at the transformer to measure the power supply of the entire transformer. In the loss of low-voltage station areas, unknown reasons accounted for 26.5%. It is different from other reasons and can formulate corrective measures. Therefore, it is urgent to develop a portable metering device to assess the power supply of the section line, so as to find out the real cause of the loss. . Cooperate with the company's line loss and construction work at the same time. [0003] The patent document with the application number 2015208453847 discloses a portable active energy metering device, which collects current information ...
