Abstract
The utility model relates to electrostatic ring positioning on end of high tension coil used by transformer to improve distribution of electric field. An insulating layer is arranged outside and an insulating paper ring with metal tape enwinding peripherally is arranged inside. At the bottom closely adjoining the area enwound by the metal tape, a ring of flat type copper wire with a gap between its head and end is arranged along circumferential direction of the electrostatic ring, and a curving lead wire made of flat copper liking a trunk is connected with lead wire of the high tension coil. No welding with tin is needed because the flat type copper wire is leaded out and connected with lead wire of the high tension coil. The utility model completely avoids being breaking off and ensures normal usage of the electrostatic ring.
Description
Technical field
The utility model is for being used for the high-tension coil end, so that improve the transformer high-voltage coil electrostatic ring of end Electric Field Distribution.
Background technology
Traditional transformer high-voltage coil electrostatic ring is to adopt metal tape to surround insulating paper circle outside, then multiply flexible cable and metal tape is connect with soldering, and the other end of flexible cable and high-tension coil lead weld with phosphor-copper.Because the fusing point of tin is lower, at a certain temperature, causes easily producing obscission between flexible cable and the metal tape, can influence the normal use of electrostatic ring.
Summary of the invention
The utility model technical issues that need to address are: a kind of obscission that no longer produces is provided, can guarantee the normal transformer high-voltage coil electrostatic ring that uses.
For solving the technical scheme that above technical problem adopts is such: the utility model has external insulation, there is the insulating paper circle the inside and surrounds the metal tape of insulating paper circle periphery, it is characterized in that: be close to the bottom that metal tape holds part, be provided with the disjunct opening flat type copper wire of a first and last circle that is made into along the electrostatic ring circumferencial direction, be provided with crooked and trunk shape flat copper lead-out wire that be connected with the high-tension coil lead in an end of opening.
After adopting above technical scheme, be connected,, thoroughly avoided obscission, guaranteed the normal use of electrostatic ring so need not soldering owing to flat type copper wire is directly drawn with the high-tension coil lead.
Description of drawings
Fig. 1 is main TV structure figure of the present utility model.
Fig. 2 is the A-A sectional structure chart of Fig. 1.
Fig. 3 is the B-B sectional structure chart of Fig. 1.
Among the figure: 1, insulating paper circle 2, metal tape 3, flat type copper wire 4, insulating barrier 5, trunk shape flat copper lead-out wire
Embodiment
When making electrostatic ring, at first use metal tape (2) to surround the periphery of insulating paper circle (1), being close to the bottom that metal tape holds part, be made into the disjunct opening circle of first and last along the electrostatic ring circumferencial direction then with flat type copper wire (3).For being difficult for being drawn out, at an end of opening, directly draw again after flat type copper wire bent to the trunk shape, draw and partly add the bag insulation and be connected with the high-tension coil lead.
Claims (1)
1, a kind of transformer high-voltage coil electrostatic ring, it has external insulation (4), there is insulating paper circle (1) the inside and surrounds the metal tape (2) of insulating paper circle periphery, it is characterized in that: be close to the bottom that metal tape holds part, be provided with the disjunct opening flat type copper wire of a first and last circle (3) that is made into along the electrostatic ring circumferencial direction, be provided with crooked and trunk shape flat copper lead-out wire (5) that be connected with the high-tension coil lead in an end of opening.
