Automatic management device for unlawful using electric in electric network

Abstract

The invention discloses a device for automatically preventing unlawful using electric in power network, which includes a base and a box fixed together with the transformer. Electric meters and an AC transformer are installed in the box, and ceramics wiring points are installed at the upside and downside of the box, and the wiring points are respectively connected via wires, and the wires go through respectively the exchange-transformer and connect directly with the output of the transformer through the wires of the ceramics wiring points downside. The wires connect with users' cable outside through the ceramics wiring points upside, and the output wires of the transformer connect respectively with the electric meters. So it can be used for preventing such as broken circuit, bypass flow, commutating, furthermore, it increases the voice circuits and high-voltage generator circuit for preventing damage about the box by purely man-made factors.

Description

[0001] Field [0002] The invention belongs to equipment provided by electric power departments to users, and in particular relates to an automatic management device for preventing power theft during power output. technical background [0003] At present, in the process of measuring three-phase electricity users in the power supply department, due to the large current used, it cannot be directly measured. Generally speaking, AC transformers are used together with electric energy meters for measurement. In this kind of metering system, change the system wiring, such as current line disconnection, shunting, commutation, phase change, transformer reverse current reverse meter, phase line and neutral line interchange, voltage line open phase, phase change, and zero line with voltage Even cutting off the metering system and other means to steal electricity is sometimes difficult for the power department to find and find. For this reason, the Patent Office has disclosed the patent ...

Problems solved by technology

In this kind of metering system, change the system wiring, such as current line disconnection, shunting, commutation, phase change, transformer reverse current reverse meter, phase line and neutral line interchange, voltage line open phase, phase change, and zero line with voltage Even cutting off the metering system and other means to steal electricity, sometimes it is difficult for the power department to find and find

For this reason, the Patent Office has disclosed the patent No. 90204318, 8 three-phase anti-stealing device technology. This patent has a certain effect on the user's arbitrarily changing the metering system wiring so that the circuit breaks, shunts, and changes direction. Line belt pressure, cutting off the metering system, prying meter box, and the prevention of theft of the whole machine are obviously insufficient, and there is no real-time monitoring and remote meter reading function.
