Description
Technical field
The present invention relates to a kind of cable leakage pick-up unit, belong to cable production art.
Background technology
The conventional construction of cable is made up of the insulating sheath of the conductor and parcel conductor that are positioned at SMIS position, current insulating sheath is elastomeric material or expanded material substantially, but no matter be elastomeric material or expanded material, the production of cable is all by wrapping up the elastomeric material after thermoplastic or expanded material is made on conductor.
Current production technology, its maximum position is cannot the accurate thickness of insulating sheath in production control process, only can accomplish roughly to determine at present, and once comprise impurity in the starting material of rubber or foaming, cause heating, careless mistake appears in encapsulation process, can leak be there is in the insulating sheath of the finished cable then produced, once this section of cable is normally used, light then cause transmission performance to decline, heavy then cause electric leakage, serious meeting causes electric shock accidents, tests in current production technology by means of only range estimation to cable insulation, obviously cannot accomplish the accuracy checked.
Summary of the invention
The present invention, for solving prior art problem, provides a kind of earth detector accurately checking cable insulation.
Technical scheme of the present invention is: a kind of cable leakage pick-up unit, comprise frame, described frame is provided with plummer, described plummer is provided with testing agency, it is characterized in that: described testing agency comprises on some loading ends being distributed in described plummer, electrical connection and the contact that can move freely within the specific limits mutually; Described testing agency is also provided with described contact mutually insulated and the signal source be electrically connected with cable under test, the signal receiver be connected with described contact electrical.
As preferably, described contact is metal small-sized chondritic.
As preferably, mutually connect and form some mutual electrical connections and the String structure covered on the loading end of described plummer in several described contact.
As preferably, described erecting is equipped with a hollow radome, and described radome covers described plummer and described contact.
As preferably, mutually connect and form some mutual electrical connections and the String structure covered on the loading end of described plummer in several described contact, described radome is respectively arranged with entrance and exit along the charging discharging direction of described plummer, and described entrance and described outlet are respectively arranged with described String structure.
As preferably, described plummer is arranged at the center of described radome, is positioned at described plummer position and is provided with described String structure in described radome.
As preferably, described radome is provided with one can the top cover of folding, and described contact all hangs on described top cover.
As preferably, described frame is provided with a distance sensing device near described plummer feed entrance point.
The present invention adopts contact measurement method, by arranging a large amount of contact at the outside surface of cable, when cable between contact through time, as insulation course is leaky, then contact can, directly with the conductor contact in cable and conducting, now only need to be energized in any one end of conductor or contact, then the other end can be energized because of the conducting of contact and conductor, as installed warning device additional at receiving end, then can report to the police to this conducting, with the reliability of detection streamer insulation course.
Further, as a rule, for qualified finished cable, insulation course is separated with between conductor and contact, therefore conductor, contact and insulation course define an electric capacity, after conductor and contact are accessed same circuit, conductor, contact and insulation course show suitable capacitive in circuit, because the resistance value of conductor and contact is determined, therefore when thickness of insulating layer changes, capacitive in circuit can change because of the change of capacitance, this pick-up unit is by the accurate measurement of circuit capacitive, can the accurate measurement of reality to cable insulation layer thickness, the quality of further lifting cable product.
The pearl string structure that contact of the present invention adopts surface coverage to make, be made up of with the metallic bond being connected bead the bead of exhibiting high surface covering metal, this structure bead quantity is large, distribution density is high, when cable passes from bead, a large amount of bead slips over from cable surface, can realize detecting cable surface non-blind area, this structure is simple simultaneously, bead can adopt the most cheap plastic or other material manufacture, surface only needs to cover one deck conducting metal, and cost is extremely low, and bead is lightweight, pressure is applied to cable surface little, therefore little to cable surface damage.
In sum, the present invention has the following advantages:
1, accuracy of detection is higher, and result is accurate;
2, can not damage cable surface, reliability is high.
