Abstract
The utility model discloses a testing terminal used for a rheological secondary circuit. The testing terminal comprises a plurality of sets of terminal bases, a plurality of sets of connecting pieces and a plurality of coupling nuts. In the normal operation, each set of connecting pieces is connected to the corresponding set of terminal bases, when short connection is required, one connecting piece in each set of connecting pieces is pulled out and then inserted in one base blind hole in the next set of bases, the sequential analogy is carried out to form the short connection of the whole rheological testing terminal, and therefore secondary security measures on a related circuit between a maintenance device and an operation device can be completed. By the adoption of the testing terminal, the operation behavior is standardized, the working efficiency is improved, and meanwhile the probability of risk occurrences is reduced.
Description
Technical field:
The utility model relates to a kind of testing terminal for rheology secondary circuit.
Background technology:
The maintenance of power system device is to guarantee the basis of electricity consumption, and protective relaying device is as ingredient important in electric system, the quality of its maintenance concern power supply safety and power supply quality.Maintainer is before doing repair based on condition of component work; to do secondary safety practice to the associated loop between repair apparatus and operational outfit; and in the process that secondary safety practice is implemented; there is the safety practice relating between main transformer and bus differential protection loop, the operation of relevant rheology testing terminal after poor screen as female in short circuit.Traditional rheological test terminal, adopts the form that adds in flakes nut, uses while connection in flakes, uses nut to be fixed in joint.Exist in use loaded down with trivial details tightening to unscrew operation, the situation of " twisting askew " occurs because nut counterpart is incorrect sometimes, not only operating difficulties, and waste time and energy.Especially easily make screw cap-falling or come off in flakes and cause short circuit phenomenon of other operation interval rheological test terminals to occur, because the metal part of metal part in flakes and testing terminal is exposed larger, easily causing operating personnel to get an electric shock simultaneously.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide one according to on-the-spot protective relaying device repair based on condition of component need of work, can carry out quickly and easily the rheological test terminal of rheological test terminal short circuit or recovery.Not only standard operation behavior, and increase work efficiency, the possibility that risk occurs reduced simultaneously.
The utility model technical solution problem adopts following technical scheme:
For the testing terminal of rheology secondary circuit, it comprises:
Organize terminal bases and organize brace, multiple coupling nut more more;
Every group of terminal base comprises two cylindric bases that are set up in parallel, two bases middle part radially between by the connection of winning in succession, the center of each base is provided with conduction copper column along axis, copper post outside is insulation crust, the top of described copper post is provided with blind hole, and copper post bottom is the terminals that are connected with electric current secondary loop; Described winning in succession as current-carrying plate, the middle part of winning in succession is provided with screw and forms and open circuit between the copper post of two bases;
Described in every group, brace comprises that two are set up in parallel in flakes, described in each, center is in flakes provided with the column copper core mating with described blind hole, described copper core outer wrap has ambroin, copper sheet by zigzag between two described copper cores connects, on described copper sheet, be provided with insulation operating handle, in two described copper cores, the top of one of them copper core is provided with central blind hole;
The center of each described coupling nut is provided with the copper screw rod mating with described screw, is provided with insulated rotary handle in the outside of described copper screw rod.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model adopts the outer Analysis of Nested Design of plug type all insulation, and terminal outer, without bare metal part, realizes timelyization simple to operate.
The copper sheet of terminal between is in flakes ladder (zigzag) design, facilitates shank when interconnected to cause extruding injury in flakes without accumulation, and the embedded design of joint inside, makes the connection between internal copper core more solid and reliable.
Brace and coupling nut have outstanding exercisable insulation handle design, while making to plug in flakes and when rotary nut stressed evenly, conveniently connect fast and accurately in flakes and disconnect.
When normal operation, coupling nut is arranged in the screw of winning in succession between two bases, between two base copper posts, forms path, can be because of open brace by mistake, and cause current return open circuit, improve security.
By above design, solve maintenance or operations staff in the process that rheology testing terminal is operated, because tradition is fastening by nut in flakes, and cause the running time long, easily touch other rheological test terminal in service by mistake and be short-circuited and the easily shortcoming such as electric shock of operating personnel.Improve staff's operating efficiency and speed, strengthened security, made whole implementation process more simple and reliable.
Accompanying drawing explanation:
Fig. 1 is overall schematic of the present utility model; 2 is the vertical view of the normal operation of testing terminal; Overall schematic when Fig. 3 is testing terminal maintenance; Fig. 4 is the cut-open view of one group of base and coupling nut; Fig. 5 is the cut-open view of one group of brace.
Number in the figure: 1 base, 2 win in succession, 3 bronze medal posts, 4 insulation crusts, 5 blind holes, 6 terminals, 7 screws, 8 in flakes, 9 copper sheets, 10 operating handles, 11 bronze medal cores, 12 ambroins, 13 central blind holes, 14 coupling nuts, 15 screw rods, 16 rotating handleses, 17 screen cabinet panels, 18 nuts.
