Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the principles of the present invention figure.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of leakage conductor on-Line Monitor Device of the present embodiment, including shell 8, the interior setting of shell 8
Acquisition unit and monitoring unit 9, shell 8 is waterproof moisture-proof, and the acquisition unit is current transformer 2, and current transformer 2 includes
Iron core 3 and secondary winding 5, the current transformer 2 are open-type mutual inductor, i.e., jaw type are arranged on the iron core 3 of current transformer 2
Opening 11.
Hall element 10 is set on the iron core 3 of the current transformer 2.
The material of the iron core 3 of the current transformer 2 is permalloy.
It further include pressing handle 4, pressing handle 4 is fixedly connected with iron core 3, and pressing handle is arranged outside shell 8, described
Pressing handle 4 can control the jaw type opening 11 of iron core 3 to open and be closed.
Fixed anchor ear 6 is arranged in the bottom of the shell 8.
The present embodiment is used for the mounted leakage conductor replacement of transmission line of electricity and when installing arrester on-line computing model additional
Hand presses handle 4 and opens jaw type opening 11 by opening fulcrum 7, passes through arrester drainage thread 1, release handle, jaw closure.
Anchor ear 6 is fixed with stainless steel again, and the arrester on-Line Monitor Device of the present embodiment is mounted on electric power line pole tower across fixation hole
On, it is easy for installation secured.
As shown in Fig. 2, the working principle of the present embodiment coil is as transformer.Primary coil is exactly across iron-core coil
Conducting wire, be equivalent to the primary coil of the transformer of 1 circle, this is a step-up transformer.Secondary coil and measurement part are constituted
Secondary circuit.When conducting wire has alternating current to pass through, it is exactly that this circle coil produces alternating magnetic field, is generated in secondary circuit
Induced current, the size of electric current and the ratio of primary current, are equivalent to the inverse ratio of the number of turns of primary and secondary coil, this coil
Turn ratio is that 1:500 is compared in fixation.Since leakage current of the arrester under power frequency operating voltage is microampere order, and add power transmission line
There is certain interference of electromagnetic field in road, considerably increases the difficulty of leakage current measurement.The material of the iron core 3 of the coil of the present embodiment
Material is permalloy, and permalloy has high magnetic conductivity under low-intensity magnetic field, so the leakage current of microampere order also can be surveyed accurately
Amount.Coupled Hall element 10 in coil, 10 output waveform of Hall element is clear, non-jitter, without rebound, positional repeatability
Height has certain magnetic field anti-interference ability, so that the leakage current measured is accurate.
The present embodiment coil collects leakage current analog signal, is amplified small-signal by AD8137, filter circuit
Signal is handled, using the control and conversion of single-chip microcontroller, starts 433 wireless communication modules for collected arrester and reveals electricity
Stream, the transmission of the data such as action frequency are sent.
To sum up, the acquisition mode of the utility model embodiment, which need to only open collecting part jaw, passes through original drainage thread
, convenient and efficient.Coil iron ring material is that permalloy has also coupled Hall element, Hall element have very high accuracy,
Sensitivity and stability, so that the arrester Leakage Current accuracy of measurement is high.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
It modifies or replaces, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
