Abstract
The utility model discloses a lightening current test device, which is mainly composed of a permanent magnet, a rotating body, a rotary shaft, a bearing, a magnetic conductive block, a half permanent magnetic material and two pole shoes which are installed on the permanent magnetic material. The permanent magnet is installed on a shaft of the rotating body, and the direction of a magnetic pole is vertical to the axial direction of the rotating body. One or a pair of the magnetic conductive blocks is respectively arranged at one end or both ends of the magnetic pole of the permanent magnet with leaving a certain interval. The two pole shoes are fixed to both ends of a permanent magnet which is on an identical plane position with the permanent magnet and the magnetic conductive block. The two pole shoes are provided with forming an angle with the magnetic conductive block relative to the central line of the rotary shaft. The interval between the two pole shoes and the permanent magnet is bigger than the interval between the magnetic conductive block and the permanent magnet. The two pole shoes are fixed at both ends of the half permanent magnetic material for forming a lightening current test element. Tested lightening current is arranged in the lightening current test element by a wire. The utility model has the advantages and the positive effects of simple structure, low cost and reliability, and completes the work to comfirm whether the lightening current passes through the wire.
Description
Technical field
This use is novel to relate to a kind of lightning current pick-up unit.
Background technology
Usually be laid on outdoor lightning arrester and easily be struck by lightning, because the lightning arrester that is struck by lightning is difficult for being identified the very difficulty so whether the inspection lightning arrester just was struck by lightning.
Summary of the invention
The purpose of this utility model provides a kind of lightning current pick-up unit, with the technical matters of the position that solves the lead place that the indication lightning current crosses.
The purpose of this utility model is achieved in that it mainly is made up of permanent magnet, rotary body, rotating shaft and bearing, magnetic inductive block, semi-hard magnetic materials and two pole shoes being installed in its two ends; Described magnetic inductive block and pole shoe are to be made of ferromagnetic material, and permanent magnet is installed on the rotation axon, and pole orientation is axially vertical with rotary body; One or a pair of magnetic inductive block are placed on the one or both ends of permanent magnet poles respectively and leave certain clearance; Described two pole shoes be seated in permanent magnet, magnetic inductive block on same planimetric position, two pole shoes and magnetic inductive block are the angle setting with respect to shaft centerline, two pole shoes apart from the gap of permanent magnet greater than the gap of magnetic inductive block apart from permanent magnet; Two pole shoes are fixed on the semi-hard magnetic materials two ends, constitute the lightning current detecting element, and the conductor that tested lightning current is passed through places in the lightning current detecting element.
The shape of described magnetic inductive block can be ball, cylinder or square.
Advantage of the present utility model and good effect: simple in structure, reliable, cheap, finish the whether work by lightning current of conductor of determining.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Structure of the present utility model is installed in permanent magnet 2 in the rotating shaft 4 of rotary body 5 referring to Fig. 1, and the pole orientation of permanent magnet 2 is vertical with the direction of rotating shaft 4.Put two magnetic inductive blocks 3 at permanent magnet 2 magnetic pole two ends, stay certain clearance between magnetic inductive block 3 and the permanent magnet 2.Certainly magnetic inductive block 3 can be one, places magnetic pole one end of permanent magnet 2, and magnetic inductive block 3 is located under state of nature for permanent magnet 2.Under state of nature, magnetic inductive block 2 is attracted by permanent magnet 3, and driven rotary body 5 rotates to the nearest position of permanent magnet 3 magnetic poles and two magnetic inductive blocks 3.Between two magnetic inductive blocks 2, put two pole shoes 1 apart from magnet 2 farther positions, because pole shoe 1 is apart from the distance of permanent magnet 2, be subjected to the suction of the suction of permanent magnet 2,, remain on original position so the position of permanent magnet 2 can not change less than magnetic inductive block 3.Put a semi-hard magnetic materials 6 that does not magnetize between the bipolar shoe 1.Conductor 7 by lightning current is seated between two pole shoes 1.When lightning current is out-of-date from conductor 7 upper reaches, magnetize to semi-hard magnetic materials in the magnetic field of lightning current, makes the semi-hard magnetic materials magnetization, and keep magnetic, by pole shoe 1 magnetic passed to around the permanent magnet 2.This moment, permanent magnet 2 was subjected to having the attraction of the pole shoe 1 of magnetic, this attractive force is greater than the attractive force of permanent magnet 2 with magnetic inductive block 3, permanent magnet 2 can revolve to turn 90 degrees and (be mutually 90 degree angles at a pair of magnetic inductive block and two pole shoes with respect to shaft centerline, when being arranged at around the permanent magnet), keep balance in distance pole shoe 1 nearest position.Permanent magnet 2 driven rotary bodies revolve and turn 90 degrees, and this position display shows lightning current conductor dbus mistake thus by lightning current.
Two used magnetic inductive blocks 3 of the utility model also can substitute with the permeability magnetic material of a U-shaped.Two terminations of U-shaped permeability magnetic material be seated in magnetic inductive block 3 in conplane position.
The shape of permanent magnet 2 can be circular, also can be strip.
This device can form a convenient lightning current pick-up unit of observing by the mode of tick lables is set, is equipped with the shell with observation panel that covers on its outside on rotary body 4 surfaces.
