Distributed low-voltage distribution network operation data acquisition system and using method thereof

Abstract

The invention discloses a distributed low-voltage distribution network operation data acquisition system and a using method thereof. The distributed low-voltage distribution network operation data acquisition system comprises a box body; the box body comprises side plates and a top plate, the side plates are provided with four, the upper end surface of each side plate is provided with a clamping groove, three clamping grooves are formed in the side plates on the front and back sides, two clamping grooves are formed in the side plates on the left side and the right side, insertion connection strips are arranged at the bottom end of the top plate corresponding to the clamping grooves, the edge of the periphery of the top plate is connected with a vertical edge plate, a metering chip, a Bluetooth module, a power-on reset circuit and a storage clock chip are arranged in the box body, an air switch is arranged on the outer wall of the box body, the air switch is electrically connected withthe metering chip through a current sampling circuit and a voltage sampling circuit, and the voltage sampling circuit is also electrically connected with the metering chip through a switching power supply and a transformer. The system disclosed by the invention has the advantages of being simple and convenient to disassemble and assemble, and high in dampproof and waterproof performance, and the function of analyzing and recording protection of the air switch is achieved.

Description

technical field [0001] The invention relates to a collector and a use method thereof, in particular to a distributed low-voltage distribution network operation data collection system and a use method thereof, and relates to the technical field of power grid equipment. Background technique [0002] With the development of the national economy and the improvement of people's living standards, users have higher and higher requirements for power quality. The evaluation of the user's power quality mainly includes the following indicators: first, voltage quality, which includes three requirements for voltage deviation, voltage fluctuation and voltage flicker, second, frequency, and third, power supply reliability, which is the distribution network There are as many as 11 evaluation indicators for the measurement of the user's continuous power supply capability, the main one is the annual average power supply reliability rate, that is, the percentage of the user's annual average po...
