Inelegant remote anti-electricity-stealing inspection method

Abstract

The invention discloses an inelegant remote anti-electricity-stealing inspection method and belongs to the field of measurement. According to the method, a fore-meter CT is arranged in front of an intelligent electric meter; a wireless current detection unit is arranged on a high-voltage line to be monitored; a magnetic-field detection unit and a high-frequency detection unit are arranged in the intelligent electric meter; an anti-electricity-stealing inspection host is arranged; a CPU of the anti-electricity-stealing inspection host receives current data, detected by the wireless current detection unit, of the high-voltage line to be monitored through a Zigbee module, extracts a fore-meter current and the collected current of the intelligent electric meter from the fore-meter CT and the intelligent electric meter, finds out an under-current electricity stealing event and specific links through comparison, finds out an under-voltage electricity stealing event by reading voltage data from the intelligent electric meter, and detects strong magnetism and high-frequency interference in the intelligent electric meter through magnetic field detection and high frequency detection; once the electricity stealing events happen, the CPU uploads a result to a monitoring center through a GPRS module. The method can be widely applied to the field of anti-electricity-stealing inspection of high-voltage power supply lines or low-voltage power supply lines.

Description

technical field [0001] The invention belongs to the field of monitoring, in particular to a monitoring method for anti-stealing electricity. Background technique [0002] With the continuous development of the electric power industry, the methods of stealing electricity are more diversified and high-tech, and the number of stealing electricity is also increasing sharply. Normal power order. Now, some high-energy-consuming enterprises, state-owned enterprises and institutions, and very few special units have also begun to steal electricity. Their high-tech stealing methods are more professional and more concealed, which has brought great trouble to the anti-stealing inspection staff. In this regard, ordinary anti-stealing technology can no longer meet the requirements, and an advanced anti-stealing equipment is urgently needed to effectively suppress rampant electricity theft, reduce national economic losses, and restore normal power consumption order.

Problems solved by technology

The 10KV high-voltage line and the 380V low-voltage power supply line are complex tree structures, and there are many power consumers, so they are the hardest hit areas for electricity theft.

Compared with 380V low-voltage power supply lines, 10KV high-voltage power lines have more households, but 10KV high-voltage power lines have a higher leakage value. The more important thing is that 380V low-voltage power lines are generally for civilian use, while 10KV high-voltage lines are generally for industrial use. From the perspective of cost and "electricity theft value", 10KV high-voltage lines are more likely to steal electricity
