Abstract
The utility model provides a connector of transformer high -tension bushing and GIS equipment room, belongs to high forced lubrication transformer technical field, characterized by: in the main side that becomes, install the inflatable terminal additional and aerify the insulating sleeve in the main set outside that uprises, high cover is electric draws forth the end and passes through electrical connection spare with the inside conducting rod in inflatable terminal and peg graft fixedly, in the GIS side, add one set of GIS terminal in GIS sleeve pipe side, change the SF6 gas -insulated mode into the air insulation mode. The beneficial effects are that: 1 ), novel owner becomes high -tension bushing and the GIS bushing mode is simple, and structural design is reasonable, and running behaviour is reliable, 2 )This kind of structure easy dismounting and have obvious cut -off point when overhauing, safety measure is reliable, 3 )Becoming main that to overhaul when experimental the wiring convenient, not opening and overhaul the hand hole, do not exhaust and overhaul the experiment work, experimental test does not have the error, the seeking of contrastive analysis when being convenient for the data exception and fault point. 4 )Change the back and only need draw absolutely when experimental, unnecessary dismouting GIS sleeve pipe, reduced work load and equipment trouble is rateed.
Description
Technical field
This utility model belongs to high force feed power transformation technology field.
Background technology
Commonly used, to replace open type switchyard in the distribution system of GIS complete set of distribution 66kV ~ 500 kV grade at home and abroad at present.Main transformer high-pressure side and GIS outlet use direct-connected mode (high set is sealed in GIS sleeve pipe) mostly, fill in view of GIS device, exhaust air technique is complicated, duration longer and that high voltage installation may be brought unstable factor, the prolongation test period is all used when each power plant carries out transformer test, or wiring at GIS grounding switch, with one section of GIS device, main transformer carried out the go forward side by side means of line number value trend comparison of walk through test and substantially judge main transformer state, owing to main transformer height set is longer to GIS controller switching equipment spacing, and it is bigger to DCR of Transformer value effect in view of the contact resistance at grounding switch, record numerical value only as reference, accurately cannot test according to preventive trial regulatory requirements.
Main transformer high-pressure side and GIS outlet use the deficiency that direct-connected mode (high set is sealed in GIS sleeve pipe) exists: SF6 gas in GIS must be reclaimed when 1, carrying out transformer test every year, open GIS hand hole, disconnected draw and connect draw, evacuation and fill the work such as SF6 gas, test typically needs 3 day time every time.2, using main transformer to send under the mode of band station service when station service electrical system, main transformer undertakes station service simultaneously and send work, and the repair time cannot be effectively ensured；3, frequently carry out the filling of SF6 gas, works of knocking off when carrying out customary main transformer preventive trial, easily make GIS device poor sealing, leak, make moist, enter dust and the leakage build environment pollution of SF6 gas；4, this kind of structure such as carries out main transformer pressure test, in addition it is also necessary to removes one section of GIS sleeve pipe and adds quantities, and is unfavorable for equipment safe and stable operation.5, the contact resistance at grounding switch is relatively big to DCR of Transformer value effect, records numerical value only as reference.
Summary of the invention
The purpose of this utility model is: provide the connector between a kind of transformer high-voltage bushing and GIS device, and it can dismount GIS sleeve pipe, decreases maintenance workload and equipment failure rate.
The technical solution of the utility model is as follows:
In main transformer side: at outside inflated type terminal and the inflatable insulation sleeve of installing additional of main transformer height set, the electric exit of high set is fixed by electrical fitting grafting with inflated type terminal inner conducting rod；
In GIS side: set up a set of GIS terminal in GIS set tube side, SF6 gas-insulated mode is changed into air insulation mode.The compound inslation skirt of exterior of terminal adds electric creep age distance.
Use flexible circuit conductor, device clamp to be connected with main transformer height locking terminal and GIS terminal terminals respectively, use bolt fixed mode.
The beneficial effects of the utility model are: 1), Novel main transformer bushing and the telescopic joint mode of GIS simple, reasonable in design, runnability is reliable；2) this kind of structure easy accessibility have obvious cut-off point when maintenance, safety measure is reliable；3) easy-to-connect when main transformer checking experiment, does not open maintenance hand hole, not aerofluxus and carries out checking experiment work, and experimental test does not has error, it is simple to relative analysis during data exception and the lookup of trouble point.4) when carrying out that main transformer is pressure waits large-scale experiment, former connected mode have to carry out dismounting and can carry out GIS sleeve pipe, only need to break and draw, it is not necessary to dismounting GIS sleeve pipe, decrease workload and equipment failure rate after change during test.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
As it can be seen, 1 be GIS terminal, 2 be device clamp, 3 be flexible circuit conductor, 4 be main transformer height set inflated type terminal, 5 be electrical fitting, 6 be inflatable insulation sleeve, 7 be main transformer height set, 8 be main transformer body.
Main transformer side: install inflation (SF6) formula terminal 4 and inflation (SF6) insulating sleeve 6 additional in main transformer height set outside, high electric exit and inflation (SF6) formula terminal inner conducting rod of overlapping is by electrical fitting 5 grafting；
GIS side: set up a set of GIS terminal in GIS set tube side, SF6 gas-insulated mode is changed into air insulation mode.The compound inslation skirt of exterior of terminal adds electric creep age distance.
Use flexible circuit conductor, device clamp to be connected with main transformer height locking terminal and GIS terminal terminals respectively, use bolt fixed mode.
By using this new Joining Structure, the electrical connection being sealed in GIS inside pipe casing is converted to connecting portion part exposed at air outside, disconnected drawing when maintenance, test, test and directly remove the wire that is flexible coupling, be very easy to overhaul, the work such as disconnected when testing is drawn, test, wiring.
