Embodiment 1

[0016] Embodiment 1: As shown in Figure 1, the device of the present invention consists of a high-voltage power collection terminal 2, a low-voltage power collection terminal 1, a wireless digital public communication network 4, a safety monitoring terminal 3, a monitoring center 5 and a mobile power supervision terminal 6. The high-voltage electric energy collection terminal 3 is installed in the feeder line, node, and the high-voltage side of the transformer to independently collect the load parameters of the 10kV (35kV) side of the distribution network; The power collection terminal 1 adopts a distribution transformer collection terminal, and the collection box is installed on the pole of the substation. The operating parameters of the transformer are collected through the combination of transformers, and the parameters of multi-channel metering meters can be collected at the same time. The parameters collected by each collection terminal are transmitted to the monitoring ce...

Embodiment 2

[0017] Embodiment 2: On the basis of Embodiment 1, if the electric energy metering device at the low-voltage side monitoring point has a data interface, the low-voltage electric energy collection terminal 1 adopts the electric energy collection terminal and is installed on the secondary outlet side of the metering transformer, through RS485 or The pulse interface collects the data of the metering device.

Abstract

The disclosed real-time method to prevent electric larceny comprises: monitoring the transformer substation pass, 10KV distribution lines, special user and public power parameter by a high-voltage electric energy collection terminal; monitoring original parameters by a low-voltage electric energy collection terminal; using a wireless digital communication network to send data to the monitor center to store in database for classification and analysis, then auto drawing load curve and charge curve for different monitor point. This invention has well monitor effect and can alarm by SMS.

Description

Technical field: [0001] The invention relates to a method and device for preventing electricity theft, in particular to a method and a device for managing electricity theft from the power supply side and analyzing and checking electricity theft from the system side. Background technique: [0002] The existing grid anti-theft methods mainly have the following problems: [0003] 1. It mainly protects the 0.4kV user-side metering device, but there are thousands of ways to steal electricity, and it cannot be effectively prevented without using the metering device to steal electricity. Therefore, any technical preventive measures aimed at a single metering device cannot effectively prevent the occurrence of electricity theft; [0004] 2. The traditional anti-stealing inspection mainly relies on manual business census, which has poor timeliness and insufficient census. It is difficult to grasp the operation status of the distribution network in real time, and it is difficult to a...
