Problems solved by technology

According to statistics, electricity theft is the main cause of non-technical line loss, but for a long time, the phenomenon of electricity theft has not been effectively curbed, and some illegal enterprises achieve the purpose of paying less electricity bills by means of under-calculation or even non-calculation of electricity. Cause a large loss of national electric energy and loss of national property
However, with the development of technology, the means of stealing electricity presents the characteristics of concealment, diversification, rapidity and high-tech, especially in the occasions where large-scale users steal electricity and use electricity, many users steal electricity with hidden means and high technological content , it is very difficult for the conventional inspection method of electricity consumption to be effective

Embodiment Construction

[0021] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0022] A photovoltaic branch monitoring system for anti-theft, such as figure 1 As shown, including three high-voltage load collectors, solar overhead substations and remote receiving terminals;

[0023] The three high-voltage load collectors are installed on the three-phase overhead high-voltage line in phases, and are used to collect three-phase high-voltage load data, and transmit the three-phase high-voltage load data to the solar overhead substation through RF wireless radio frequency communication. , while completing high voltage safety isolation;

[0024] The solar overhead substation is fixed on the pole through a hoop, receives the three-phase high-voltage load data sent by the three high-voltage load collectors in real time through RF wireless radio frequency communication, and synchronizes the three high-voltage loads through time synch...

Abstract

The invention relates to a photovoltaic branch monitoring system used for electricity steeling prevention. The photovoltaic branch monitoring system is technically characterized by comprising three high voltage load acquisition devices, a solar overhead substation and a remote receiving terminal. The output ends of the high voltage load acquisition devices are connected with the solar overhead substation. The output end of the solar overhead substation is connected with the receiving terminal. An external power supply is not required, and installation and disassembling are not interfered without power outage so as to be simple and convenient, great in concealing and low in cost and economical and practical. Besides, selectable and replaceable multimode high voltage load acquisition devices and the solar overhead substation are utilized to perform group notification of relevant personnel and form three-dimensional evaluation groups, the acquired three-phase high voltage load data are screened and analyzed in a targeted way, electricity steeling users are accurately determined, and inspectors, experts and leaders are enabled to simultaneously perform analysis and communication online so that large amount of manpower and material resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of power metering, and relates to a reliable appliance for preventing electricity theft, in particular to a photovoltaic branch monitoring system for preventing electricity theft. Background technique [0002] The development of the national economy has promoted the rapid development of electric power construction, and the gradual improvement of the power consumption information collection system has promoted the improvement of line loss management. According to statistics, electricity theft is the main cause of non-technical line loss, but for a long time, the phenomenon of electricity theft has not been effectively curbed, and some illegal enterprises achieve the purpose of paying less electricity bills by means of under-calculation or even non-calculation of electricity. Cause a large loss of national electric energy and loss of national property. However, with the development of technology, the means of...
