Description
COUP~ING UNI~ FOR CONNECTION OF HIGH~VO~TAGE GElYERA-~OR WINDING LEAD-OU~ ~ND CABLE.
The present invention relates to elec-trical industry and, in particular, to cable couplings and specifically to a coupling unit for connection of a lead-out of a high--voltage generator winding and a cable~
The invention can be used in manufacturing high-power generators, including turbo generators, for thermal and nu-clear power plants and heavy-duty transformers.
Modern electrical engineerlng tend~to use higher voltage in power transmission lines, transformers and ge-nerators in an attempt to increase their e~ficiency and minimize their dimensions.
However, the use of high and superhigh.~voltages brings in the problem of designing coupling units for connection of various electrical elements, for eæample units to couple high-voltage cables to aerial lines or cable lead-in9.f~r trans~ormers.
One way of coupling a high-voltage generator to other electrical devices consists in connecting an oil-filled ~ ~ cable of a high-voltage generator stator winding to an oil-: -filled cable joining the high-voltage generator to a high-. _voltage station or line.
The closest prototype of the present invention is a : coupling unit for connection of a lead-out o~ a high-vol-tage generator wi~ding and a cable linking said lead to . ~
external elec-trical apparatuses, which is made as a cable joint box /V.A.Priveze~sev, E.P. ~arina, Power Cables and High-Voltage Cable Lines. 1970, ~nergia Publ., Moscow, pp.72-73, 77-79. (in Russian)/.
The known coupling unit comprises a casing ~illed with a~ insulating substance, for example oil, wherein the cable termination ~eaturing a capacitor splice and the lead-out of the generator high-voltage winding, featuring sheaths and a capacitor splice, are ~rrangeà~ the curren-t--carrying elements thereof being coupled to one another, both the lead-out of the generator high-voltage winding and the cable termination being encased into an insulating hermeticall~ sealed coàting.
~ he known coupli~g unit is characterized by irregular distribution of voltage throughout the surface o~ the splice of the cable termination which is depe~dent upon the capacitance between the plates of said capacitor spli-ce and upon the capacitance between the plates of the cable termination splice and the casing.
Irregular distribution of voltage throughout the sur-~ace o~ the capacitor splicing of the cable termination may result in rupture of insulation whereever the inten-sity o~ the electrical field is the greatest. The capacitor splicing of the cable termination is made very long in order to eliminate the possibility of such ruptures in the known coupling unit ~or connection o~ the high-voltage

The capacitor splicing of the cable termination is made very long in order to eliminate the possibility of such ruptures in the known coupling unit ~or connection o~ the high-voltage
- 2 -116~416 generator winding and the cable, which makes the unit bulky.
It is an object of the present inve~ion to provide a more compact coupling unit for connection of a generator high-voltage winding lead-out ~ld a cable joining the ge-nerator to external electrical apparatuses.
Another object of` the invention is to provide a more reliable coupling unit for connection o~ a generator high--voltage winding lead-out and a cable aoining this genera-tor to external elec-trical apparatuses.
The invention essentially resides in -tha-t in a coup-ling unit for connection of a generator high-voltage wind-ing lead-out and a cable, comprising a casing filled with an insulation substance and accomodating a cable terminati-on with a capacitor splice and a lead-out of a generator high-voltage winding, featuring sheaths and a capacitor splice, whose current carrying elements are connected to one another, the lead-out of the generator high-voltage winding being encased into an insulating hermetically sealed coating, according to the in~ention, the sheaths of the ge-nerator high-voltage winding lead-out are made as a system of concentric cylinders, which form at the edge of the lead--out a capacitor splice, contact rings being arranged on the surface of the capacitor splice of the generator high--voltage winding lead-out at a certain distance Prom one another, each such ring being connected to its sheath of the generator high-~oltage winding lead-out, which has a 116~16 specific electric potential, whereas the plates of -the capacitor splice of the cable termination are connected to its con~ac-t ring~s arranged on the surface of the ca~acitor splice o~ the cable termination, each contact ring located on the capacitor splice of the generator high-voltage winding lead-out in the plane parallel to the plane extending through the beginning of this capacitor splice and at a specific ~niform distance between said planes being joined by means of a strap to a contact ring located on the capa-citor splice of the cable termination in the plane paral-lel to the plane extending through the beginning of the capacitor splice o~ the cable termination and at the same specific distance ~etween latter planes, whereas the cur-rent car~ying elements of the ~enerator high-voltage wind-ing lead-out and the cable termination are linked by means of a power jumper.
~ he use of the invention permits significant reducti-on of the dimensions o~ the coupling unit ~or connection of a generator high-voltage winding lead-out and a cable and, consequently, manufacture of high-power generators with a stator winding voltage of up to 500 kV. Besides, the use of the invention permits a substantial incLease in the operational reli~ity of the coupling unit for con-nection of a generator high-voltage winding lead-out and a cable, as well as o~ the generator as a whole through a more effective voltage compensation throughout the surface of the capacitor splice of the cable termination.
' llS5416 Given herein below is a detailed description o~ an exemplaI~ embodiment o~ the present invention, reference being had to the accompanying drawing illustrating a lon-~itudinal section view of a coupling unit for connection of a generator high-voltage winding lead-out and a cable joiniDg the generator to external electrical apparatuses, according to the invention.
A coupling unit for connection of a generator high--voltage winding lead-out and a cable joining -the generator to external electrical apparatuses comprises a casing 1 filled with an insulation substance, for example insulating oil 2. The casing 1 accomodates a termination 3 of the cab-le joini~g the generator to external electrical apparatu-ses~ featuring a capacitor splice 4 and a lead-out 5 of the generator high-voltage winding, featuring sheaths 6 and a capacitor splice 7. The sheaths ~ of the lead-out 5 of the generator high-voltage winding are a system of con-centric cylinders which form at the edge thereof the ca-pacitor splice 7. A capacitor splice here means the fa~ned out bell end of the cable insulation, which forms a cone of insulation layers alternating with conducting layers, the tip of the cone being the core of the current carrying wire of the cable. Current carrying elements 8 of the -ter-mination 3 and of the lead-out 5 are linked b~ means of a jumper 9. The lead-out 5 of the generator high-voltage winding is encased into an insulating tight coating 10 which is intended for separation of the oil systems of the generator high-voltage winding lead-out and the cable.
116~16 Contact rings 12 are spac0d a certain distance ap~rt on the surface of the capacitor splice 7 o~ the lead-out 5, each ring 12 being linked with its sheath 6 of the lead--out 5 having a specific electric potential.
~ he c~pacitor splice 4 o~ the termination 3 o~ the cable joining the generator to external apparatuses is provided with plates 11 connected to the contact rings 12 arranged on the surface of the capacitor splice 4.
Each contact ring 12 located on -the capacitor splice 7 of the lead-out 5 of the generator high-vol-tage winding in a plane running parallel to a plane extending through beginning of said capacitor splice 7 c~nd at a specific distance between said planes is linked by means of a jum-per 13 to the contact ring 12 located on the capacitor splice 4 of the termination 3 in a plane running parallel to a plane extending through the beginning of the capaci-tor splice 4 of the cable termination 3 and at the same distance between latter planes.
_Qp~ings in the casing 1 for letting through the cab-le termination and the lead-out of the generator high-vol-tage winding are sealed by gaskets 14.
In cable terminations operating conditions of insula-tion are extreme since the electric field produced at the edges of the termination is highly irregular and ruptures are a frequent occurance. In order to improve conditions of the insulation the termination is fanned out or spliced.
~o ob~ain ~avourable voltage distribution along the surfa-116S~16 ce of the splice, the latter should be large enough. ~he distribution of voltage along the surface of the capacitor splice is affected by the capacitances between the plate system of the splice, the current carrying elements of the cable termination and grounded elements of the coupling unit for connection of the ge~erator high-voltage winding lead-out and the cable. Voltage throughout the sur~ace of the capacitor splice can be compensated b~ making the spli-ce larger.
~ hus, for example, with the line voltage of 220 kV in the cable the capacitor splice is about two meters long.
~his entails a signi~icant increase of the overall dimensi-ons of the coupling unit of the generator high-voltage windi~g lead-out.
~ he jumpers 13 provided in -the proposed coupling unit for connection of ~ generator high-voltage winding lead-o~t and a cable permit setting of specific voltage on the pla-tes 11 of the capacitor splice of the termination 3 and, consequently, eliminating the effect of the capacitances between the system of plates 11 of the capacitor splice 4, the current carrying elements 8 of the cable term;nAtion 3 and grounded elements o~ the coupling unit for connection o~ a generator high-voltage windin$ lead-out and a cable and~ moreover, arranging adjioning plates 11 at a minimum distance dictated by the electrical endurance o~ inaula-tion with the given voltage drop between said plates 11.
~he voltage drop for any pair o~ adjoi~ing plates 11 is -- 7 ~
a constant quantity defi~ed by the potential difference of the neighbouring sheaths 6 of -the generator high-voltage winding lead-out 5. ~ince the generator high-voltage winding is in fact a multilayer cable and each shea-th 6 of the generator high-voltage winding lead-out is linked to its current carrying layer of the cable, the potential diffe-rence of the sheaths 6 is kep-t constant.
The herein described coupling unit for connection of a genera-tor high-voltage winding lead-out and a cable pro-vides an opportunity to connect the generator high-voltage winding lead-out to several cable terminations joining the generator to various power consumers with var~ing angles between the geome~trical axis of the generator winding lead-~-out and the geometrical axes o~ the cable terminations.
~ he proposed invention permits a substantial reducti-on of the dimensions and an increase of reliability of the coup~ing unit for connection of a generator high-voltage winding lead-out and a cable, as well as o~ the generator as a whole.
