Electricity or the situation without electricity, it is ensured that contactless on-Line Monitor Device safe and stable operation, and the charge inducing in the present embodiment
Aggregation apparatus small volume is easily installed maintenance, and cost is relatively low.
The operation principle of overhead transmission line electricity getting device in the present embodiment is：Due to what is circulated in overhead transmission line
It is that electromagnetic field can be produced around alternating current, alternating current, charge inducing aggregation apparatus 101 is arranged on the electricity of overhead transmission line
It is used to sense and assemble electric charge in magnetic field.Charge collection gap discharge device 102 is provided with gas gap, so can be first by institute
The electric charge that the charge inducing aggregation apparatus 101 of connection is assembled is saved bit by bit, is waited and is reached that a certain amount is enough to puncture the gas
Discharged again during gap, so disposably just there can be larger electric current, the electric current is used.
Wherein, charge collection gap discharge device 102 is the core component of overhead transmission line electricity getting device, as needed
Set the breakdown voltage (such as 200V) of the gas gap, the sensing connected in charge collection gap discharge device 102
When the electric charge that accumulation device 101 is assembled saves bit by bit a certain amount, the voltage at the two ends of charge collection gap discharge device 102
Difference reaches the breakdown voltage of the gas gap, punctures the gas gap, the electric charge that charge inducing aggregation apparatus 101 is assembled
Low potential point is flowed to, the flow direction of electric charge forms ion channel so that place (gas gap) connection disconnected originally.Due to needing
Want electric charge just to puncture the air gap when saving bit by bit a certain amount of, then release, this pulse current is called short pulse, electricity
Stream actual measurement should be able to reach 10mA, and this is than larger to be sufficiently used for powering for contactless on-Line Monitor Device.Discharged with
Afterwards, the voltage difference at the two ends of charge collection gap discharge device 102 does not reach gap breakdown voltage, charge inducing aggregation apparatus again
101 slowly assemble electric charge to reach the purpose of electric discharge next time again.Because the electromagnetic field that overhead transmission line is produced exists always, because
