Abstract
The utility model relates to an electricity leakage detector, belonging to the detecting technique of electric signal, which is formed by that a needle-shaped detecting head is added on the basis of an original plier-shaped amperometer. In this way, the electricity leakage points of light electric power wires can be detected by making use of a plier-shaped detecting head, and the electricity leakage points of dark electric power wires can be detected by making use of the needle-shaped detecting head. The front end of the needle-shaped detecting head is made of metal materials with a definite mechanical strength and superior electrical conductivity; the front end of the needle-shaped detecting head is connected with the wire core of a shielded conductor; the outer surface of the front end of the needle-shaped detecting head and the wire core are coated with one layer of an insulating layer; the outside of the insulating layer is provided with a shielding layer; the outermost surface is a protection insulating layer.
Description
The utility model relates to a kind of electric signal measurement instrument.
At present, in order to survey the leakage on the power circuit, utilize the pincerlike leakage current table of making according to electromagnetic induction principle usually, it is mainly by detecting head, and links such as signal amplifier and display are formed.Publication number is the utility model patent of CN85202641U disclosed " a pincerlike leakage current table detection system ", owing to adopt manganese-zinc ferrite as pincerlike detecting head magnetic core, manufacture the outer radome of magnetic core coil with permalloy, thereby improved the performance of anti-electromagnetic interference (EMI); Again owing to adopted the non-linear amplifier that constitutes by linear amplifier and gamma corrector, thereby on principle, can eliminate nonlinearity erron.But this pincerlike leakage current table can only be surveyed such as outdoor empty stringing and indoor open-wire lines such as outer naked wire, but can't measure for the leakage that is embedded in the concealed wire in underground or the wall.
The purpose of this utility model provides a kind of not only energy measurement open-wire line leakage, but also energy measurement concealed wire leakage is many with the electric leakage detection instruments.
The utility model increases a needle probe that is used for surveying the concealed wire leakage again on the basis of above-mentioned pincerlike leakage current table detection system.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a theory diagram of the present utility model
Fig. 2 is the structural drawing of needle probe
The implication of mark sequence number is as follows among the figure:
1 represents the aciculiform detecting head, 2 are the pincerlike detecting head of representative, and 3 represent range selector, and 4 represent linear amplifier, 5 represent gamma corrector, 6 represent rectification circuit, and 7 is display, and 8 is aciculiform detecting head front end, 9 is that insulation is wrapped up in to the greatest extent, 10 is screen layer, and 11 wrap up in layer for external insulation, and 12 is the core of shielded conductor.
Aciculiform detecting head front end 8 usefulness have the metal material of certain physical strength and excellent conductive capability and make, and be connected with the core 12 of shielded conductor, be wrapped with a layer insulating 9 in their outside, the outside of insulation course 9 is screen layers 10, and outermost is that external insulation is wrapped up in layer 11.
