Abstract
A wiring apparatus used for checking a sulfur hexafluoride density relay, relating to the checking and wiring technology field of a sulfur hexafluoride density relay in an electric power system, helps to solve problems that a conventional sulfur hexafluoride density relay wiring apparatus is liable to be poor in contact or to be connected by mistake because of a narrow checking space of binding posts to lead to low checking efficiency during a checking process. One end of each of six first leads is connected with one corresponding terminal of six terminals of a sulfur hexafluoride density relay, and the other end of each first lead is connected with one corresponding first binding post of six first binding posts. Six second binding posts are each connected with one end of each corresponding second lead of six second leads, and the other end of each second lead is used for being connected with a power consumption device. One end of each of six single-phase connection sheets A is connected with each corresponding first binding post, and a recess of the other end of each single-phase connection sheet A is in clamped connection with each corresponding second binding post. The wiring apparatus is suitable for wiring a sulfur hexafluoride density relay during a checking process.
Description
Technical field
The utility model relates to sulfur hexafluoride density relay verification wiring technique field in electric system.
Background technology
Being applied at present electric system SF6 density monitor verification termination is to comprise that by six fish mouth clips two lockings, two warnings, two signal groups form together, by six clips are fixed on corresponding density monitor connection terminal, to reach the object of verification wiring.But because present used clip is short and small, and density monitor is inner at SF6 circuit breaker base, the verification space of connection terminal is also narrower and small, need operating personnel that head is stretched into base inside to determine terminal label, then six clip correspondences are connected, cause six clips can not be convenient, fast, firmly receive on connection terminal, thereby cause misconnection or loose contact, verification efficiency low.
Summary of the invention
The utility model is in order to solve existing sulfur hexafluoride density relay termination due to the verification narrow space of connection terminal, the situation that easily occurs loose contact or misconnection, cause the inefficient problem of verification in checking procedure, a kind of termination for sulfur hexafluoride density relay verification has been proposed
Termination for sulfur hexafluoride density relay verification comprises wire of the six roots of sensation, six connection terminals, No. two wires of the six roots of sensation, six No. two connection terminals and six single-phase braces, and one end of a wire of the described six roots of sensation is connected with six terminals of sulfur hexafluoride density relay respectively; The other end of a wire of the described six roots of sensation is connected with six connection terminals respectively; Six No. two connection terminals are connected with one end of No. two wires of the six roots of sensation respectively; The other end of No. two wires of the described six roots of sensation is all for accessing power device; One end of six single-phase braces is connected with six connection terminals respectively, and one end of each single-phase brace can be all that axle rotates along a connection terminal; The other end of each single-phase brace all has recess, and the external diameter of the internal diameter of this recess and No. two connection terminals adapts; The recess of six single-phase brace other ends respectively with six No. two connection terminal clampings.
It also comprises shell, and described six single-phase braces are installed in enclosure.
Beneficial effect: the termination for sulfur hexafluoride density relay verification the utility model proposes is at actual verifying work, only six single-phase braces need be disconnected respectively, then the fish mouth clip of tester is connected with corresponding single-phase brace, can realize the verification operation to sulfur hexafluoride density relay, in whole operating process, be to carry out in density monitor outside, technician is easy to just can complete accurate wiring, avoid the problem of misconnection or loose contact, thereby improved verification efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
