Abstract
The invention discloses a switching tube for switch density relay test and micro-water test connectors, and belongs to the field of maintenance and test devices for power systems. The switching tube comprises switching tube connectors, a tube, fasteners, hexagon nuts and connectors; the switching tube connectors are connected with each other by the tube; the fasteners are fixedly connected with the switching tube connectors; the hexagon nuts are fixed onto the fasteners; the connectors are connected with micro-water test instrument. The switching tube has the advantages that the traditional density relay test connectors can be replaced, and accordingly the work efficiency is improved; the superiority and the reliability of the novel connectors are displayed as compared with the traditional test connectors, high test efficiency is guaranteed in a maintenance procedure, and the power supply reliability is guaranteed; total required connector replacement time for a density relay test and a micro-water test in the maintenance and test procedure is 10 minutes instead of the original 18 minutes for a 220kV circuit and is 6 minutes instead of the original 10 minutes for a 66kV circuit, the test efficiency is improved, and the test time is shortened.
Description
Technical field
The invention belongs to electric system checking experiment device field, particularly relate to the transition of a kind of SF6 switch density monitor test and little water test joint.
Background technology
In the operation of electric system checking experiment, the density monitor verification of SF6 switch and little water test do not have the common trial joint at present.Carry out in the maintenance process at the scene, need chemically examine little water test of specialty and the SF6 switch density monitor verification work of instrument specialty respectively, if two specialties are carried out work in same work place, then normally utilize two cover test joints to be connected with Switch main body air release interface.
Because switch density monitor venting valve port overhauls use for a long time, be easy to be worn, the test joint contacts unreal with the venting valve port, thereby causes causing in the process of the test gas leakage.In carrying out little water test and density monitor checking procedure, it is very long that the maintainer changes the joint required time, and change little water test joint and density monitor joint T.T. in maintenance process: the 220kV circuit is 18 minutes, and the 66kV circuit is 10 minutes.In the SF6 switch interruption maintenance process, it is longer that the maintainer changes test joint required time, is the main key factor that influences test efficiency, reduces work efficiency, influenced the power supply of switch reliability.Because switch manufacturer difference, density monitor test joint is very many, and the X-over of development in 2011 is not the very identical coupling 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 invention provides the transition of a kind of switch density monitor test and little water test joint, can replace with traditional density monitor test joint, and then increase work efficiency.
The transition of a kind of switch density monitor test and little water test joint comprises transition piece, conduit, buckle, hexagonal nut, joint, and described transition piece is connected by conduit; Described buckle is fixedlyed connected with transition piece; Described hexagonal nut is fixed on the buckle; Described joint is connected with little water test instrument.
Be provided with the spring lockset in the described transition piece, buckle is fixedlyed connected with transition piece by the spring lockset.
Described hexagonal nut be shaped as six prisms, the inboard is the external thread shape.
Described joint is the internal thread shape.
Beneficial effect: the present invention can replace traditional density monitor test joint, and then increases work efficiency.Demonstrate superiority and the reliability of this novel joint with respect to the traditional experiment joint, guarantee the high efficiency tested in the maintenance process, guaranteed the reliability of power supply.Density monitor verification and little water test are changed required T.T. of joint in the checking experiment process, 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.

Embodiment
As shown in Figure 1, the transition of a kind of switch density monitor test and little water test joint comprises 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 fixedlyed connected with transition piece 1; Described hexagonal nut 4 is fixed on the buckle 3; Described joint 5 is connected with little water test instrument.
Be connected with the little water test instrument plug portion of developmental tube is chosen 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 twists with plank for convenient, and the 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 that matches with conduit.
Little water test joint after the transition piece part can and be reequiped is complementary, and inside is spring lock, can pin joint, and intermediate conductor partly is special-purpose developmental tube, and this pipe has antifreeze, sun-proof effect.
The part that transition is connected with density monitor test joint matches with 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 the oblique chute base plate, threaded anchor rod 1 bolt enters into rubber mat plate 3, plays better fixation by reinforced concrete 2 simultaneously.
