Description
Technical field
The present invention relates to a kind of cable leakage detection means, belong to cable production art.
Background technology
The conventional construction of cable is made up of the insulating sheath of the conductor positioned at SMIS position and parcel conductor, and current is exhausted
Edge sheath is essentially elastomeric material or expanded material, but either elastomeric material or expanded material, and the production of cable is logical
The elastomeric material or expanded material crossed after parcel is heated and softened on conductor are made.
Current production technology, its maximum position be cannot in precise control production process insulating sheath thickness, mesh
Before be only capable of accomplishing substantially determining, once and impurity is included in rubber or the raw material of foaming, cause heating, encapsulation process to occur becoming unwoven or untiwisted
Can there is leak, once this section of cable is normally used, gently then cause transporting in leakage, the then insulating sheath of the finished cable for producing
Can decline, heavy then cause electric leakage, serious meeting causes electric shock accidents, only by estimating to cable insulation in current production technology
Test, it is clear that the accuracy of inspection cannot be accomplished.
The content of the invention
The present invention is to solve prior art problem, there is provided a kind of earth detector that can accurately check cable insulation.
The technical scheme is that：A kind of cable leakage detection means, including frame, are provided with carrying in the frame
Platform, testing agency is provided with the plummer, it is characterised in that：The testing agency is distributed in the plummer including some
Loading end on, the contact that is electrically connected to each other and can move freely within the specific limits；The testing agency be additionally provided with
The contact mutually insulated and the signal source being electrically connected with cable under test, the signal receiver being electrically connected with the contact.
Preferably, the small-sized chondritic that the contact is made for metal.
Preferably, several contacts are serially connected to be formed and some being electrically connected to each other and covering holding for the plummer
String structure on section.
Preferably, the frame is provided with a hollow radome, the radome covers the plummer and described
Contact.
Preferably, several contacts are serially connected to be formed and some being electrically connected to each other and covering holding for the plummer
String structure on section, the radome is respectively arranged with entrance and exit along the charging discharging direction of the plummer, institute
State entrance and the outlet is respectively arranged with the String structure.
Preferably, the plummer is arranged at is located at the plummer in the center of the radome, the radome
Position is provided with the String structure.
Preferably, the radome is provided with a retractable top cover, the contact is hung on the top cover.
Preferably, being provided with a distance sensing device near the plummer feed entrance point in the frame.
The present invention uses contact measurement method, and a large amount of contacts are set by the outer surface of cable, when cable from contact it
Between through when, such as insulating barrier is leaky, then contact directly can contact and turn on the conductor in cable, now only need in conductor
Or contact either end is powered, then the other end can be powered because of the conducting of contact and conductor, such as install warning device additional in receiving terminal,
This conducting can then be alarmed, to detect the reliability of cable insulation.
Further, typically, for qualified finished cable, due to being separated with insulating barrier between conductor and contact,
Therefore conductor, contact and insulating barrier form an electric capacity, when conductor and contact access same circuit after, conductor, contact and
Insulating barrier shows suitable capacitive in circuit, because the resistance value of conductor and contact determines, therefore when thickness of insulating layer hair
Changing, the capacitive in circuit can change because of the change of capacitance, the accurate measurement that this detection means passes through circuit capacitive,
Can the real accurate measurement to cable insulation thickness, the quality of further lifting cable product.
The bead string structure that contact of the invention is made of surface covering, bead and connection by exhibiting high surface covering metal
The metallic bond of bead is constituted, and the structure bead quantity is big, distribution density is high, when cable from bead through when, a large amount of beads from
Cable surface is slipped over, and is capable of achieving to detect cable surface non-blind area, while this simple structure, bead can use most cheap plastics
Etc. material manufacture, surface is only needed to cover one layer of conducting metal, and cost is extremely low, and bead is lightweight, and cable surface is applied to press
Power is small, therefore damages small to cable surface.
In sum, the present invention has advantages below：
1st, accuracy of detection is higher, as a result accurately；
2nd, cable surface will not be damaged, reliability is high.
