Problems solved by technology

[0005] (3) The incoming line of the metering box is mostly single-phase, which is likely to cause problems of unbalanced three-phase and large single-phase load;
[0006] (4) The lock of the metering box is severely damaged by man-made external forces, and the problems of power consumption without meters and electricity theft outside the meters are prominent

Embodiment 1

[0030] A method for situational awareness of line loss and electricity theft inspection in a digital station area, including a metering box 1, a branch box 2, a JP cabinet 3, a concentrator 4, and a first digital terminal 5, and the metering box 1 is connected to the branch box 2 through a cable Make the branch box supply power to the metering box 1, connect the branch box 2 to the docking port of the JP cabinet 3 through the cable, and connect the JP cabinet 3 to the concentrator 4 that can actively upload events through the cable, and the inside of the metering box 1 The first digital terminal 5 is installed, combined with a new concentrator with extended functions (the station area identification function is added in particular), to realize functions such as household variable relationship identification, station area topology automatic drawing, and real-time monitoring of the quality of electric energy meters.

[0031] The branch box 2 includes a first open-type current tra...

Embodiment 2

[0036] A method for line loss situation awareness and electricity theft inspection in a digital station area. The method for line loss situation awareness and electricity theft inspection is as follows:

[0037] S1. The power outage sensing module 53 built in the first digital terminal 5 installed inside the metering box 1 predicts the user's power outage information, and collects the main circuit current, active power, power factor, and built-in relay status of each user's electric meter in real time. Associated judgment of power outages;

[0038] S2. When the user electric energy meter is out of power, the carrier module inside the metering box 1 transmits the power outage event to the concentrator 4, and the concentrator 4 uploads the event information to the collection system to actively push the meter box or household power outages to the monitoring platform of the intensive management and control center;

[0039] S3. The electricity theft warning module 54 has a built-in...

Abstract

The invention discloses a digital transformer area line loss situation awareness and electricity stealing inspection method. The method is characterized in that a metering box, a branch box, a JP cabinet, a concentrator and a first digital terminal are included, functions of station-box-household file identification, station area topological structure drawing, node electricity larceny stopping early warning, line aging early warning, electric energy meter misalignment warning and the like can be realized only by modifying and upgrading original acquisition equipment and an electricity larcenyearly warning module without changing the installation architecture of a transformer area, a line, a branch box, a metering box and an electric energy meter in the prior art. The method is advantagedin that terminal layer equipment can achieve one machine multiple purposes without much modification and expansion, development cost is low, and implementation cost is low.

Description

technical field [0001] The invention relates to the field of digitized stations, in particular to a method for situational awareness of line loss in a digitized station and electricity stealing inspection. Background technique [0002] The low-voltage power grid is the weakest link in the entire power supply network, and it is also a high-incidence area that causes complaints. The construction of the ubiquitous Internet of Things digital platform aims to build a "strong front-end" of the power grid, improve the power supply service capability and level, and implement the State Grid Corporation of China. With the customer-centered service concept, explore the path of digital technology construction, build a modern distribution network with reliable operation, standardized processes, lean operation, interconnection, information sharing, and ubiquitous integration; provide strong technical support for high-quality power supply services, currently , to conduct a thorough investi...
