Abstract

The invention belongs to a power transmission and transformation equipment detection apparatus of the electric power industry, and specifically relates to an electric leakage positioning transmittingdevice of a low-voltage meter box. The electric leakage positioning transmitting device of a low-voltage meter box comprises a power supply circuit, a setting circuit, a display circuit, an audible and visual alarm circuit and a reset circuit, and is characterized in that the electric leakage positioning transmitting device of a low-voltage meter box is further provided with a control circuit, a communication circuit and an electric leakage acquisition and detection circuit, wherein the control circuit includes: a C8051F330D singlechip U5, a diode D14, a triode V7, an electrolytic capacitor C20, resistors R17, R30, R31, R32, R33, and R34, and capacitors C17, C19, and C21. The electric leakage positioning transmitting device of a low-voltage meter box can prompt electric leakage of the meter box through audible and visual alarm, sends the prompt to a mobile phone of a line attendant in a short message in a short time, and indicates the number, the specific position, the time of electricleakage, and the state of the electric leakage meter box, thus enabling the line attendant to quickly arrive at the site of accident to process, and reducing the accident probability caused electricleakage of the box body. The electric leakage positioning transmitting device of a low-voltage meter box has the advantages of simple structure, small size, low cost and high reliability.

Description

technical field [0001] The invention belongs to a detection device for power transmission and transformation equipment in the electric power industry, in particular to a low-voltage meter box leakage location sending device. Background technique [0002] At present, there are a large number of low-voltage meter boxes used in electricity-consuming units and residents, and they are widely distributed, and they are in a complex external environment for a long time. If they are exposed to wind and sun for a long time, it is easy to leak electricity and cause danger. However, the existing meter box lacks a leakage alarm sending device, and the line inspector can only check the distribution meter box and auxiliary equipment one by one, which consumes a lot of manpower and material resources. At the same time, the leakage is not found in time, prolonging the failure time and increasing safety. risk, resulting in large losses. Contents of the invention [0003] The purpose of the...
