Intelligent low voltage shunt monitoring device

Abstract

The invention discloses an intelligent low voltage shunt monitoring device. The device comprises a power supply module used for supplying electricity, an MCU, an analog acquisition module and a communication module, the analog acquisition module and the communication module are connected with the MCU separately, the analog acquisition module is used for acquiring current and voltage signals and then sending the signals to the MCU, and the MCU is used for calculating corresponding electric energy according to data obtained through sampling of the analog acquisition module. Accordingly, currentand voltage data of a line is collected through the analog acquisition module and sent to the MCU, the MCU calculates the corresponding electric energy according to the data obtained through samplingof the analog acquisition module, a line fault is indicated through line overflowing judgement and pressure and no pressure judgement, and analysis result data is sent to a master station through thecommunication module. Accordingly, the equipment line running state can be monitored for 24 hours, and an efficient and reliable power supply is guaranteed. The fault state of the equipment line can be monitored effectively, the time cost and economic cost of manual fault finding and eliminating are lowered, and great convenience and guarantees are brought to safe and reliable running of a low-voltage power distribution network.

Description

technical field [0001] The invention relates to the field of line operation monitoring of a distribution network, in particular to an intelligent low-voltage shunt monitoring device. Background technique [0002] In the power system, the power consumption of low-voltage power distribution accounts for a large proportion, and it is very closely related to industrial and agricultural production and people's life. Therefore, in the link of "power consumption", it is almost all in the category of low-voltage power distribution network. . [0003] The characteristics of my country's low-voltage distribution network mainly include large load, dense, complex structure, etc., and the low-voltage distribution network is divided into urban low-voltage distribution network and rural low-voltage distribution network from a regional perspective. The urban low-voltage distribution network has the characteristics of complex structure, large power, and safe power supply. The city has a lar...

Problems solved by technology

[0004] More than 80% of current customer complaints and on-site failures come from the low-voltage side of the station area. Effective monitoring of the operating conditions on the low-voltage side will greatly help improve customer service quality. Through indirect feedback from the assessment table or low-voltage meter in the station area, it is impossible to simultaneously count the transformer line loss, and the abnormal power consumption of the special transformer user cannot be effectively checked and located. It can only be measured and sorted out manually, resulting in an extreme shortage of human resources. Big waste, and the effect is not obvious
