Abstract
A switch conduit of a joint for a switch between a density relay test and a slug test belongs to the field of electric power system maintenance testing apparatuses. The switch conduit comprises switch conduit joints, a conduit, a buckle, a hexagonal nut and a joint. The switch conduit joints are connected through the conduit. The buckle is fixedly connected with one switch conduit joint. The hexagonal nut is fixed on the buckle. The joint is connected with a slug test instrument. The switch conduit can replace a conventional density relay test joint. The working efficiency is thus improved. Compared with a conventional test joint, the joint provided by the utility model has greater advantages and reliability. The high testing efficiency during a maintaining process is guaranteed. The power supply reliability is also ensured. The total required time for replacing the joint for a switch between the density relay test and the slug test during a maintenance testing process is reduced from 18 minutes to 10 minutes with respect to a 220kV line and further reduced from 10 minutes to 6 minutes with respect to a 66kV line. The testing efficiency is improved. The testing time is shortened.
Description
Technical field
The utility model belongs to electric system checking experiment device field, particularly relates to the transition of a kind of SF6 switch density relay test and slug test joint.
Background technology
In the operation of electric system checking experiment, the verification of SF6 switch density relay and slug test do not have the common trial joint at present.Carry out at the scene in maintenance process, need to chemically examine respectively the SF6 switch density relay verifying work of professional slug test and instrument specialty, if two specialties are carried out work in same work place, normally utilize two cover test joints to be connected with Switch main body air release interface.
Because switch density relay venting valve port overhauls use for a long time, be easy to be worn, test joint contacts unreal with the venting valve port, thereby causes in process of the test causing gas leakage.In carrying out slug test and density monitor checking procedure, it is very long that the maintainer changes the joint required time, and in maintenance process, change slug test joint and density monitor joint T.T.: the 220kV circuit is 18 minutes, and the 66kV circuit is 10 minutes.In SF6 switch interruption maintenance process, it is longer that the maintainer changes the test joint required time, is the main key factor that affects test efficiency, reduces work efficiency, affected the power supply of switch reliability.Due to switch manufacturer difference, the density monitor test joint is very many, and the X-over of development in 2011 is not very joint match of each joint.
In sum, the art is needed badly and is wanted a kind of new technical scheme to solve this problem.
Summary of the invention
Technical matters to be solved by this invention: the utility model provides the transition of a kind of switch density relay test with the slug test joint, can replace with traditional density monitor test joint, and then increase work efficiency.
The transition of a kind of switch density relay test and slug test joint, comprise transition piece, conduit, buckle, hexagonal nut, joint, and described transition piece is connected by conduit; Described buckle is fixedly connected with transition piece; Described hexagonal nut is fixed on buckle; Described joint is connected with the slug test instrument.
In described transition piece, be provided with the spring lockset, buckle is fixedly connected with transition piece by the spring lockset.
Described hexagonal nut be shaped as six prisms, inboard is the external thread shape.
Described joint is the internal thread shape.
Beneficial effect: the utility model can replace traditional density monitor test joint, and then increases work efficiency.With respect to the traditional experiment joint, demonstrate superiority and the reliability of this Novel joint, guarantee the high efficiency of testing in maintenance process, guaranteed the reliability of power supply.In the checking experiment process, density monitor verification and slug test are changed required T.T. of joint, and 220kV circuit T.T. consuming time dropped to 10 minutes by 18 minutes; 66kV circuit T.T. consuming time dropped to 6 minutes by 10 minutes, improved test efficiency, reduced test period.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the front view of the transition of a kind of switch density relay test of the utility model and slug test joint.
Fig. 2 be the test of a kind of switch density relay of the utility model with the transition of slug test joint in be connected with the slug test instrument concrete enforcement figure of plug portion of developmental tube.

1-transition piece, 2-conduit, 3-buckle, 4-hexagonal nut, 5-joint in figure.
Embodiment
As shown in Figure 1, the transition of a kind of switch density relay test and slug test joint, comprise transition piece 1, conduit 2, buckle 3, hexagonal nut 4, joint 5, and described transition piece 1 is connected by conduit 2; Described buckle 3 is fixedly connected with transition piece 1; Described hexagonal nut 4 is fixed on buckle 3; Described joint 5 is connected with the slug test instrument.
Be connected with the slug test instrument plug portion of developmental tube, choose a high-quality cylindricality copper billet, and buckle forward part length is 11mm, and center section length is 3mm, and aft section length is 2mm; The hexagonal nut appearance design becomes six prisms, and each cross-sectional length is for convenience of twisting with plank, and inboard is designed to the external thread shape, in order to be connected reliably with next part, prevents gas leakage; Joint is the internal thread shape, is made into the joint matched with conduit.
Slug test joint after the transition piece part can and be reequiped is complementary, and inside is spring lock, can pin joint, and intermediate conductor is partly special-purpose developmental tube, and this pipe has antifreeze, sun-proof effect.
The part that transition is connected with the density monitor test joint matches with the density monitor test joint, and a spring lockset is arranged, and can pin the joint buckle, prevents from collapsing out, and causes conduit gas leakage.
Using method: utilize threaded anchor rod 1 that rubber mat plate 3 is placed on oblique chute base plate, threaded anchor rod 1 bolt enters into rubber mat plate 3, by reinforced concrete 2, plays better fixation simultaneously.
