Technical Field
The invention relates to the technical field of power line safety protection, in particular to a real-time alarming, positioning and self-healing device for power transmission and distribution line electric leakage.
Background
Defeated, distribution and transformer circuit erect subaerially, utilize insulator and air insulation's power line, overhead line exposes in atmospheric environment, can directly receive meteorological condition's effect, and simultaneously, the thunderbolt attacks, rain, wet fog and nature and industry filth etc. also can destroy or reduce transmission line's dielectric strength and even cause the power failure accident, transmission line in case the electric leakage condition appears in the use, because present transmission line does not have monitoring device, do not in time feed back the circuit electric leakage condition to relevant maintenance personal, electric leakage department can not in time maintain and will bring very big potential safety hazard for near personnel.
Disclosure of Invention
The invention provides a real-time alarm, positioning and self-healing device for electric leakage of a transmission and distribution line, which aims to solve the problem that the safety of the transmission line without a monitoring device is low in the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides a transmission and distribution line electric leakage real-time warning location self-healing device, includes induction coil, electric leakage alarm mechanism and support, and induction coil installs on the transmission pole of transmission line cross arm below, and electric leakage alarm mechanism installs on the support on the transmission pole.
The electric leakage alarm mechanism consists of a zero sequence current transformer, an A/D processor, a data module and a CPU module, wherein the zero sequence current transformer is connected with the CPU module through the A/D processor, the CPU module is connected with a data transmitting antenna through the data module, and a photoelectric isolator and a digital-to-analog converter are arranged between the CPU module and an outlet voltage.
The working principle of the invention is as follows: if the electric transmission line has an electric leakage phenomenon, an induction coil arranged on a power transmission pole near the electric leakage can convert voltage and current changes into digital signals through a zero sequence current transformer and then input the digital signals into a CUP module, if the zero sequence current value is out of limit, whether the line voltage has a voltage value needs to be detected, the outgoing line voltage is detected through a digital-to-analog converter and a photoelectric isolator, if the voltage is detected, the leakage protector is in fault, and the CPU module can send an alarm signal to related personnel through a data module and a data sending antenna.
