Description
Technical field
The utility model relates to a kind of device, particularly a kind of Transformer Bushing Tap device.
Background technology
Along with the fast development of China's economy and power industry, the wherein apparatus insulated fail safe of reliability to whole power supply unit of higher requirement is had to have very important effect to the reliability of supply of electric power, transformer high-voltage condenser-type terminal is as one of power equipment important in electrical network, the insulator arrangement of its not still wire ground, also be responsible for the effect of anchor leg simultaneously, end shield is the important component part of condenser-type terminal, be mainly used in and ground equipotential link, be in operation ground connection, untie during preventive trial, to measure capacity and the dielectric loss of sleeve pipe, for detection thimble partial discharge and partial discharge of transformer extract the number of winning the confidence.End shield device conduction is bad or lost efficacy; often cause low-yield partial discharge; even cause bushing explosion; therefore; when power equipment runs, the necessary reliable ground of end shield, just can play the effect of protection capacitor core; thus improve the electrical insulation properties of sleeve pipe, ensure the normal operation of power equipment.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of Transformer Bushing Tap device, end shield and ground equipotential link can be made, be in operation ground connection, untie during preventive trial, to measure capacity and the dielectric loss of sleeve pipe, for detection thimble partial discharge and partial discharge of transformer extract the number of winning the confidence.
The utility model solves the technical scheme that its technical problem adopts: the utility model is by circlip for shaft, copper sheathing, sealing gasket, stem, first circlip for hole, lower cover, shell, upper cover, screw, second circlip for hole, sealing ring and protective cover composition, it is characterized in that: circlip for shaft is enclosed within copper sheathing and is also connected with shell, copper sheathing is stuck in shell, shell is connected with sealing gasket, sealing gasket is connected with protective cover, there are lower cover and upper cover inside the shell, stem is through copper sheathing, lower cover, after upper cover, top is connected with screw, first circlip for hole to be enclosed within stem and to be stuck in lower cover, second circlip for hole is enclosed within stem and is also connected with upper cover, sealing ring is had between shell and protective cover, spring housing is at lower cover, on stem between upper cover.
Owing to adopting technique scheme, the advantage that the utility model has and good effect are: structure is simple, and easy to use, reliability is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Figure of description is structural representation of the present utility model.
1. circlips for shaft, 2. copper sheathing, 3. sealing gasket, 4. stem in figure, 5. the first circlip for hole, 6. lower cover, 7. shell, 8. upper cover, 9. screw, 10. the second circlip for hole, 11. sealing rings, 12. protective covers, 13. springs.
Embodiment
In Figure of description, circlip for shaft (1) is enclosed within copper sheathing (2) and is above also connected with shell (7), copper sheathing (2) is stuck in shell (7), shell (7) is connected with sealing gasket (3), sealing gasket (3) is connected with protective cover (12), lower cover (6) and upper cover (8) is had in shell (7) inner side, stem (4) is through copper sheathing (2), lower cover (6), after upper cover (8), top is connected with screw (9), first circlip for hole (5) is enclosed within stem (4) and goes up and be stuck in lower cover (6), second circlip for hole (10) is enclosed within stem (4) and is above also connected with upper cover (8), sealing ring (11) is had between shell (7) and protective cover (12), spring (13) is enclosed within lower cover (6), on stem (4) between upper cover (8).
Function and the operation principle of each parts of the utility model are: for ensureing to install simply, ensure that upper cover (8) can not be deviate to cause failure of apparatus simultaneously, stem (4) and lower cover (6) adopt the first circlip for hole (5), second circlip for hole (10) coordinates fixing with screw (9), lead-out wire is fixed on stem (4) by screw, protective cover (12) adopts with shell (7) and is threaded, all adopt sealing gasket (3) to seal at protective cover (12) and shell (7) contact-making surface simultaneously, its Main Function is the sealing of protection end shield device entirety, prevent due to end shield device long term exposure in atmosphere, cause inner components generation corrosion failure or cause the situations such as electric leakage due to rainwater, protective cover (12) bottom opening, be convenient to passing of lead-out wire, lead-out wire and protective cover (12) adopt seal protection at perforate position, can effectively prevent dust and moisture from entering like this, ensure the sealing of protective cover (12), for the ease of in installation process, observe the Grounding of end shield device intuitively, in the design, open on upper cover (8) top one with draw the suitable hole of column diameter, enclose markings in stem (4) terminals initial position processing one and paint red, like this when stem (4) is subjected to displacement by spring (13) pressure, the misalignment of stem (4) can be seen intuitively from stem (4) markings, be convenient to earthing detection, thus effectively avoid the situation of the device imperfect earth caused due to Rig up error, for ease of installation and removal, stem (4) is when designing, require that terminals exceed shell edge slightly, like this use screw lead-out wire is connected with stem time more for convenience, stem (4) and the bite of upper cover (8) can not be there is when dismantling simultaneously, preventing lead-out wire from coming off, during initial condition, under the effect of spring (13), it is inner that lower cover (6) is pressed in shell (7), and stem (4) is in initial condition along with the location of lower cover (6), when stem (4) pressurized, the lower cover (6) fixing with stem (4) is subjected to displacement thereupon, spring (13) compresses, so just effectively can ensure that stem (4) ground connection is good, simultaneously, red tag line on stem (4) leaves initial position, and whether the installation so just can observing end shield device is intuitively correct.When installing preparation, first should observe stem (4) tag line initial position, after installation, by observing tag line position judgment, correctness being installed, connecting lead-out wire after inspection and protective cover (12) is installed.
