Embodiment 2

[0063] Example 2 as Figure 7 As shown, this embodiment is a three-phase four-wire anti-stealing device, and its working principle is basically the same as that of the single-phase power in Embodiment 1. Its circuit has three phases of A, B, and C, so it has three phase splitters and phase combiners as in Embodiment 1, but the phase difference between each phase is 120 degrees, and the three phases of its transmission current are mutually loops. Therefore, when the three-phase load is basically balanced, its neutral current is basically zero.

[0064] Through a large number of experiments and tests, after stealing electricity from illegal users, the usage of some household appliances is as follows:

[0065] 1. Inductive loads: such as air conditioners, refrigerators, fans, washing machines, electromagnetic cookers, electric frying pans, microwave ovens, rotatable electric heaters, etc. cannot be used, and if they are hung on the line for a long time, they may cause damage.

Abstract

The invention provides an electricity larceny prevention method and a device. The method aims at carrying out technical measures over such public stealing electricity, characteristic attributes of sine alternating current are disorganized at a power supply terminal, and then the sine alternating current is sent on a power transmission circuit, reverse technical measures are adopted when the current reaches a power usage end, characteristic attributes of the sine alternating current are restored. For illegal users stealing electricity in the power transmission way, the stolen electric power is abnormal alternating current and cannot be normally used, partial family appliances can be damaged so that the power for stealing electricity is lost, and no electricity is gradually stolen. For the legal users, due to the fact that reverse technical measures are adopted at the power using end, the characteristic attributes of the sine alternating current are restored, so that the method for using the alternating current is as same as that of the common electricity, and no difference exists.

Description

technical field [0001] The invention relates to the field of electric property safety, in particular to an anti-stealing method for preventing illegal users from pulling wires privately and directly stealing electricity during electric power transmission, and an anti-stealing device for realizing the method. Background technique [0002] For unattended power consumption facilities, such as communication base stations, the electricity is generally taken from the public power grid nearby, and is transmitted to power consumption facilities, such as communication base stations, through power metering devices, switches and security devices, power transmission lines (or cables), etc. ,Such as figure 1 Shown: the high-voltage mains is transformed by a transformer to generate the currently used 220VAC (single-phase) voltage, or three-phase 380VAC, which is transmitted from the power supply end to the power consumption end through the power transmission line. From figure 1 It can b...
