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.

Embodiment 1

[0023] Embodiment 1, as shown in Fig. 1, Fig. 2; 3 is box body and it and base 19 are a whole, and base 19 is firmly fixed together with power transformer, and electric energy meter 5 is contained on the rear wall of box body, four Only AC transformers E, F, G, and Q are evenly distributed under it. The upper and lower ends of the box are respectively equipped with ceramic terminal blocks A', B', C', D' and A, B, C, D, etc. There are wires 6 connected between A' and A; between B' and B There is a wire 7 connection between C' and C; there is a wire 11 connection between C' and C; there is a wire 12 connection between D' and D, and the wires 6, 7, 11, and 12 pass through the AC transformers E and F respectively during the connection process. , G, Q, and are directly connected to the output line of the transformer in the base 19 through the connection between the ceramic terminal blocks A, B, C, and D at the lower part of the box body, where D is connected to the zero line, and t...

Embodiment 2

[0024] Embodiment 2, this embodiment is basically the same as Embodiment 1, but for the convenience of the power supply department to remotely control the supply of power, an AC contactor 21 is housed in the box, which is controlled by the circuit in the control box 17. Wireless transmission and reception are two-way, so the management department can easily control the opening and closing of the AC contactor 21 through wireless signals in the control center, thereby realizing remote control of power supply. In order to increase the deterrent force to lawless personnel and reduce its damage to equipment, this embodiment has increased voice alarm and high-voltage electric shock device, as shown in Figure 4 and Figure 5, IC1 in Figure 4 is the voice specific integrated circuit model is ISD1420, it It forms a voice input storage system with surrounding components. IC2 is a voice amplification integrated circuit model LM386D. LE1 is a high-brightness light-emitting tube in the figur...

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 ...
