Electricity larceny prevention and detection device for buried cable

Abstract

The invention discloses an electricity larceny prevention and detection device for a buried cable. The electricity larceny prevention and detection device comprises a CPU module, wherein the CPU module comprises a startup module, a transmission module, a processing module, a signal amplification module and a power supply module. The electricity larceny prevention and detection device can measure current values of multiple points simultaneously, realizes transmission within 100 m in a 433 MHz wireless manner, and realizes wireless transmission to a master station through crossing obstacles; the master station is used for comparing different phase discrimination data and calculating magnitude of line loss of each phase; a measuring head and a wireless transmission unit are separately designed, thus the electricity larceny prevention and detection device is portable and facilitates subsequent maintenance; and the electricity larceny prevention and detection device saves labor and time, can complete the detection by a single person, and controls the single-household detection time to be less than 10min.

Description

technical field [0001] The invention relates to a detection device, in particular to a buried cable anti-stealing detection device, which belongs to the technical field of low-voltage line current detection. Background technique [0002] The traditional verification method of electricity inspection is to refer to the line loss of the entire line, combined with the on-site inspection of the metering device. With the increase of electricity customers, the wiring of low-voltage lines is becoming more and more complicated, and the concealment of electricity theft is enhanced and the situation of direct burial of cables is increasing. Therefore, after determining that there is a possibility of electricity theft in a low-voltage line, it is particularly necessary to measure the line loss of each phase in sections, and then gradually narrow the scope, so as to enhance the pertinence of the inspection object. [0003] Furthermore, the most direct way to check low-voltage lines on si...

Problems solved by technology

[0003] Furthermore, the most direct way to check low-voltage lines on site is to compare the current of the main line with the sum of the currents of each branch line to check whether there is any phenomenon of stealing power such as privately connected lines. Due to the real-time and random nature of line load, in The measured value at the same time has reference significance. The traditional verification method is to measure with clamp ammeters by multiple people at different places at the same time, and use mobile phones to communicate and confirm, which is cumbersome and time-consuming

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
