Problems solved by technology

[0003] However, the strategy adopted by the existing monitoring terminals transmits data to the server for analysis and processing. Due to the time delay in the data transmission from the terminal to the server, the collected data cannot be filtered and analyzed in real time, and in the face of When a large amount of data is uploaded by the terminal, it will bring greater operating pressure to the server, which is not conducive to the stable operation of the system

Abstract

The invention discloses a composite monitoring and analyzing device and method based on current and temperature of a power line. The method comprises the following steps: step S1, a temperature and current relation model of a cable is analyzed and acquired by using a credible method; S2, a three-phase current and a three-phase wire skin temperature are measured by using each sensor clamped at the monitoring part of the three-phase cable; S3, the sub-sensor transmits current, temperature and cable health state data to the main sensor through the wireless module, and the main sensor calculates a low-voltage outgoing line load rate and a low-voltage outgoing line three-phase unbalance degree; and S4, the main sensor determines a switch load condition and a cable health condition according to the obtained data and a calculation result, sends an alarm signal of a corresponding grade according to a judgment result, and sends the alarm signal to the gateway through the concentrator in a wireless mode.

Description

technical field [0001] The invention relates to the technical field of power line monitoring, in particular to a composite monitoring and analysis device and method based on power line current and temperature. Background technique [0002] my country's early power distribution network has been basically formed, and most of the old-fashioned power distribution rooms do not have the conditions for power outage operations. When carrying out intelligent transformation of the power distribution room, a critical step is to install a monitoring terminal on the head side of the low-voltage outgoing cable. Currently, existing monitoring terminals transmit all collected data to a server, and the server performs all data analysis and processing. [0003] However, the strategy adopted by the existing monitoring terminals transmits data to the server for analysis and processing. Due to the time delay in the data transmission from the terminal to the server, the collected data cannot be ...
