Abstract
The utility model discloses a density relay secondary cable core gui ji device, its characterized in that is equipped with the cross -section and is square strip base member, and the strip base member is divided into seven units along length direction, and every unit of terminal surface evenly is equipped with three heart yearn binding post before the strip base member, and every unit of strip base member rear end face is equipped with a binding post, and three heart yearn binding post is linked together with binding post after the switch of strip base member up end is parallelly connected, has following advantage: firstly, effectual two drawbacks of pressing of terminal row sinle silk of having avoided have avoided connecing the problem that the signal transfer that leads to did not go out because of the cable is virtual, secondly, it needs the loaded down with trivial details degree of dismouting plug box to have simplified the check -up of density relay greatly, thirdly, imitate and reduced the density relay and install the short circuit risk that exists additional in put into operation back and the density relay check -up working process.
Description
Technical field
This utility model relates to powering in power system utensil, a kind of simple to operate, density monitor secondary cable core apparatus for collecting that work efficiency is high.
Background technology
For power supply safety, clear stipulaties " chopper of 220kV and above GIS branch mailbox structure installs independent density monitor the most accordingly " in 18 anti-accident measures of State Grid Corporation of China, but the GIS device put into operation before 2006 mostly is three-phase and shares a density monitor, it is unsatisfactory for above-mentioned anti-clause of arranging, need to carry out biphase installing remaining additional air chamber density monitor, need to be parallel to together by the cable of three-phase density monitor during loading densities relay, traditional construction method is to B phase by A phase signals line parallel, be in parallel C phase the most again by B, backstage protection device is passed to through cable after.The drawback that this technique exists be secondary cable plug box in need to crimp the cable core of more than two in a terminal block; it is to easily cause cable core to crimp loosely less than one, makes warning that air chamber pressure is low or block signal can accurately not pass to backstage protection device；Two is to easily cause cable plug box bonnet lid not go up and produce the problems such as short circuit.Simultaneously when carrying out density monitor verifying work, device plug box of need to density being added some points is pulled down, then by verification wire clamp on the binding post of density monitor, operation is complicated, work time and effort consuming, further, since binding post spacing is less, during test, easily cause output short-circuit.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, propose a kind of simple to operate, connect the density monitor secondary cable core apparatus for collecting reliable, work efficiency is high.
This utility model can be reached by following measure:
A kind of density monitor secondary cable core apparatus for collecting, it is characterized in that being provided with the strip matrix that cross section is square, strip matrix is divided into seven unit along its length, the each unit of strip matrix front end face is uniformly provided with three heart yearn binding posts, the each unit of strip matrix rear end face is provided with a binding post, and three heart yearn binding posts are connected with binding post after the switch in parallel of strip matrix upper surface.
The corresponding each heart yearn binding post in strip matrix upper surface described in the utility model is provided with LED and turns on display lamp, quickly to judge duty.
The switch of strip matrix upper surface described in the utility model is provided with side and is connected with three heart yearn binding posts, the platen that opposite side is connected with binding post, one end of depression bar is connected with platen, the other end of depression bar is connected with pressure handle, spring it is cased with on depression bar, platen and three heart yearns connect a terminal and binding post is separated under the action of the spring, overcome spring force that platen and three heart yearns can be made to connect a terminal and binding post contacts, to reach the purpose of quick-make and separation when pressing pressure handle.
Three-phase density monitor cable core is respectively connected to heart yearn binding post by this utility model, solve in chopper three-phase density monitor secondary cable core parallel process, need to crimp the deficiency of more than two cable cores on connecting terminal block in secondary cable plug box, have the advantage that one is that core collects entrance and the outlet form with " 2 enter 7 goes out ", effectively avoid the drawback of the double pressure of terminal block core, it is to avoid the signal caused because of cable virtual connection transmits the problem do not gone out；Two is that three-phase density monitor core parallel connection can be switched on or switched off by the design form of the breaking device " press disc type " of switch easily in device, and enormously simplify density monitor verification needs to dismount the fussy degree of plug box；Three be effect reduce density monitor install additional put into operation after and density monitor verifying work process present in short-circuit risks.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model front end face.
Fig. 2 is the structural representation of this utility model rear end face.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
nullAs shown in the figure，A kind of density monitor secondary cable core apparatus for collecting，It is characterized in that being provided with the strip matrix that cross section is square，Strip matrix is divided into seven unit 2 along its length，The each unit of strip matrix front end face 2 is uniformly provided with three heart yearn binding posts 3，The each unit of strip matrix rear end face 2 is provided with a binding post 4，Three heart yearn binding posts are connected with binding post after switch 5 parallel connection of strip matrix upper surface，The corresponding each heart yearn binding post in described strip matrix upper surface is provided with LED and turns on display lamp 1，Quickly to judge duty，The switch of described strip matrix upper surface is provided with side and is connected with three heart yearn binding posts，The platen that opposite side is connected with binding post，One end of depression bar is connected with platen，The other end of depression bar is connected with pressure handle，Spring it is cased with on depression bar，Platen and three heart yearns connect a terminal and binding post is separated under the action of the spring，Overcome spring force that platen and three heart yearns can be made to connect a terminal and binding post contacts when pressing pressure handle，To reach the purpose of quick-make and separation，Three-phase density monitor cable core is respectively connected to heart yearn binding post by this utility model，Solve in chopper three-phase density monitor secondary cable core parallel process，Need to crimp the deficiency of more than two cable cores on connecting terminal block in secondary cable plug box，Have the advantage that one is that core collects entrance and the outlet form with " 2 enter 7 goes out "，Effectively avoid the drawback of the double pressure of terminal block core，Avoid the signal caused because of cable virtual connection and transmit the problem do not gone out；Two is that three-phase density monitor core parallel connection can be switched on or switched off by the design form of the breaking device " press disc type " of switch easily in device, and enormously simplify density monitor verification needs to dismount the fussy degree of plug box；Three be effect reduce density monitor install additional put into operation after and density monitor verifying work process present in short-circuit risks.
