The outdoor voltage transformer is in an integral structure in which an iron core, a primary winding, a secondary winding, a primary sleeve insulating post and a secondary wiring box are subjected to compound insulation through epoxy resin and silicon rubber. The integral structure is wholly mounted on a groove-shaped base; the primary sleeve insulating post is cylindrical; and the high-voltage fuse protector is arranged inside the primary sleeve insulating post in a sealed manner. The outdoor voltage transformer provided by the utility model has the advantages of small size, compact structure, stable insulation, pollution flashover resistance, protection function of the fuse protector, convenience in dismounting and mounting, power function, and large output capacity.
Description
Technical field
The utility model relates to the voltage transformer field, a kind of specifically outdoor band fuse voltage transformer.
Background technology
Outdoor voltage transformer is the equipment of measuring voltage in the electric power system, electric energy or relaying protection; Especially pushing forward comprehensively along with national distribution automation work; Various intelligent outdoor on-pole switchs and demarcation switch adopt in a large number, and outdoor voltage transformer function is proposed more requirement, except that requiring product to have little, in light weight, the no oiling of volume, the performance such as non-maintaining; Require product will carry functions such as high pressure insurance, charged source winding in addition; Satisfy the requirement of supporting automation complete set of equipments, and the product that does not also have this performance on the present industry though can extraly increasing, existing dry type product is adorned outdoor fuse apparatus; Thereby overall structure is oversize and equipment cost increases, and has increased a lot of difficulties for simultaneously the work such as plant maintenance in later stage.
The utility model content
Existing electric power system distribution automation equipment volume is big, structure is cumbersome and outdoor voltage transformer is not with problems such as protection in order to solve, and the utility model provides that a kind of volume that adopts epoxy resin and silicon rubber compound inslation to form is little, compact conformation, insulation is stable, resistant is dodged, be with the fuse defencive function, easy accessibility, charged source function, open air band fuse voltage transformer that output capacity is big.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of outdoor band fuse voltage transformer; Be integral the formula structure by iron core, winding, secondary winding, sleeve pipe insulated column and secondary connection box through epoxy resin and silicon rubber compound inslation; This integral structure integral installation is on the grooved base; A sleeve pipe insulated column is a drum, and inner envelope is put high-tension fuse.
A said sleeve pipe insulated column is that benchmark outwards tilts with symmetry angle with the center line of this integrative-structure.
A said sleeve pipe insulated column end adopts swivel nut bolt mode to be fixed with the primary connection terminal, and joint is equipped with rubber sealing boot.
The main chute skirt that a said sleeve pipe insulated column outside is evenly distributed with equidistantly, extension elongation equates.
In the said integrative-structure, the main insulation body top that envelope is put iron core, winding, secondary winding and a secondary connection box is spherical structure, and the outside, center is evenly distributed with equidistantly, extension elongation is equal attaches full skirt.
Said secondary connection box is positioned at the front side bottom or the positive bottom of main insulation body.
The utlity model has following advantage:
1. little, the compact conformation of volume: two sleeve pipe insulated column inside are sealed with high-tension fuse respectively No. one time, have effectively utilized the space of instrument transformer, and small product size is little, and compact conformation reduces the overall dimensions of outdoor on-pole switch.
2. stable, the resistant sudden strain of a muscle of insulation: adopt reasonable structural design; Guarantee that product has very big surface insulation; The silicon rubber insulation material has good tracking resistance and electrical erosion resistance ability in addition, has improved pollution flashover voltage widely, can prevent the generation of pollution flashover fault effectively.
3. be with the fuse defencive function; Easy accessibility: product indoor design autogamy is the high-tension fuse defencive function once; The protection product can not damage when effectively protection was broken down in system, and the Rational structure design makes the change of fuse dismounting convenient, guarantees the safe and reliable operation of complete set of equipments.
4. charged source function, output capacity are big: the product secondary has the power supply independent winding, and output capacity is big, not only guarantees the power requirement of outdoor switch protective device, and the instant action can effectively guarantee fault actions the time.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
Shown in Fig. 1-3, the utility model comprises among the figure: 1 iron core; 2 windings; 3 secondary winding; No. 4 sleeve pipe insulated columns; 5 secondary connection boxes; 6 grooved bases; 7 high-tension fuses; 8 primary connection terminals; 9 rubber sealing boots; 10 main chute skirts; 11 main insulation bodies: 12 attach full skirt.
No. one time sleeve pipe insulated column 4 is a drum, and as the space that envelope is respectively put high-tension fuse 7, the protection product can not damage when effectively guaranteeing to break down in system.Two sleeve pipe insulated columns 4 are that benchmark outwards tilts with symmetry angle with the center line of integrative-structure, increase product phase insulation distance, and help sleet, water and dirt etc. and slip out smoothly.Primary connection terminal 8 adopts swivel nut bolt modes to be fixed on sleeve pipe insulated column 4 ends No. one time, and joint is equipped with rubber sealing boot 9, link to each other smoothly with the system equipment high-voltage electrical apparatus, and guarantee waterproof sealing insulation under the outdoor running environment reliably.The main chute skirt 10 that sleeve pipe insulated column 4 outside are evenly distributed with equidistantly, extension elongation equates can effectively strengthen instrument transformer surface creepage distance, increases insulation level, guarantees pollution flashover voltage can not occur.Main insulation body 11 tops that envelope is put coil device body are the spherical structure form, guarantee that outdoor running environment sleets, water and dirt etc. slip out smoothly.The outside, main insulation body 11 center that envelope is put coil device body is evenly distributed with equidistantly, extension elongation equates attaches full skirt 12, further strengthens the surface creepage distance of product, the insulation level of increase product.Secondary connection box 5 forms for integral structure is integrated poured with main insulation body 11, is positioned at the front side bottom or the positive bottom of main insulation body 11, can effectively guarantee the sealing of secondary connection terminal, can the short circuit because rainwater soaks, corrosion.
During use, high-tension fuse 7 is packed in the sleeve pipe insulated column 4 of instrument transformer, suit rubber sealing boot 9 back envelopes are put primary connection terminal 8.Require to carry out grooved base 6 according to outdoor switch and install, carry out the connection of primary connection terminal 11 and secondary connection at last again, outdoor band fuse voltage transformer installment work is accomplished.
