An intelligent low-voltage shunt monitoring device

Abstract

The invention discloses an intelligent low-voltage shunt monitoring device, comprising: a power supply module for power supply, an MCU, an analog acquisition module and a communication module respectively connected to the MCU, and the analog acquisition module is used to collect current and voltage signals and send them to MCU, the MCU is used to calculate the corresponding electric energy according to the data sampled by the analog acquisition module. The present invention collects the current and voltage data of the line through the analog acquisition module and sends it to the MCU. The MCU calculates the corresponding electric energy according to the data sampled by the analog acquisition module, and then indicates the line fault through the line overcurrent judgment and voltage-free judgment. The analysis result sends the data to the master station through the communication module. The invention can monitor the operation state of equipment lines in 24 hours, and ensures efficient and reliable power supply. It can also effectively monitor the fault state of the equipment line, reduce the time cost and economic cost of manual troubleshooting, and bring great convenience and guarantee to the safe and reliable operation of the low-voltage 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
