Abstract
The application relates to bushing for transformer field, particularly a kind of insulating sleeve of 10kV transformer.The application provides a kind of insulating sleeve of 10kV transformer, comprise body and be set at least three spaced full skirts on body, also comprise the secondary full skirt be made up of insulating material, secondary full skirt is arranged between adjacent two full skirts, secondary full skirt open direction and full skirt to open direction identical, the size of secondary full skirt is less than the size of full skirt.The application increases the creepage distance of insulating sleeve, makes insulating sleeve that sliding sudden strain of a muscle be less likely to occur, improves circuit safety.
Description
Technical field
The application relates to bushing for transformer field, particularly a kind of insulating sleeve of 10kV transformer.
Background technology
The insulating sleeve of transformer is the insulating element guided to by inside transformer high and low pressure outside fuel tank, not only as lead-in wire insulation against ground, but also is responsible for the effect of anchor leg.The insulating sleeve of transformer is one of current carrying element of transformer, for a long time by load current, passes through short circuit current when transformer short-circuited outside.Therefore, require that there is the electrical strength of regulation and enough mechanical strengths, require that insulating properties is good simultaneously.
Usually the insulating sleeve be used on 10kV main transformer is made up of the porcelain bushing of multiple hollow cylindrical, and on the outer wall of each porcelain bushing, interval is alternately provided with the full skirt of multiple porcelain.As shown in Figure 1, because 10kV transformer have employed single insulating sleeve, its creepage distance is less, if when height above sea level is comparatively large or air gradation for surface pollution is higher, sliding sudden strain of a muscle easily occurs, produces fault.
Summary of the invention
The application provides a kind of insulating sleeve of 10kV transformer, solves in prior art, and sliding sudden strain of a muscle easily occurs insulating sleeve, produces the problem of fault.
The application provides a kind of insulating sleeve of 10kV transformer, comprise body and be set at least three spaced full skirts on body, also comprise the secondary full skirt be made up of insulating material, secondary full skirt is arranged between adjacent two full skirts, secondary full skirt open direction and full skirt to open direction identical, the size of secondary full skirt is less than the size of full skirt.
Preferably, the opening angle of secondary full skirt is less than the opening angle of full skirt.
Preferably, the spacing distance between adjacent two full skirts is more than or equal to 40mm.
Preferably, the shape of full skirt is identical with size, and the shape of secondary full skirt is identical with size.
Preferably, full skirt is provided with three, and secondary full skirt is provided with two.
Preferably, the height of full skirt is 20mm, and the height of secondary full skirt is 20mm.
The beneficial effect of the application is, comprise body due to the application and be set at least three spaced full skirts on body, and also comprise the secondary full skirt be made up of insulating material, secondary full skirt is arranged between adjacent two full skirts, secondary full skirt open direction and full skirt to open direction identical, the size of secondary full skirt is less than the size of full skirt.Like this, the secondary full skirt of increase just increases creepage distance, makes insulating sleeve that sliding sudden strain of a muscle be less likely to occur, improves circuit safety.
Accompanying drawing explanation
Fig. 1 is the end view of prior art insulation full skirt;
Fig. 2 is the end view of embodiment 1;
Fig. 3 is the cutaway view of embodiment 1.
Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Embodiment 1:
An insulating sleeve for 10kV transformer, as depicted in figs. 1 and 2, at least three the spaced full skirts 2 comprising body 1 and be set on body 1, body 1 and full skirt 2 are all be made up of insulating material, Ceramics in the present embodiment.Insulating sleeve also comprises the secondary full skirt 3 be made up of insulating material, and secondary full skirt 3 is made up of pottery in the present embodiment.Secondary full skirt 3 is arranged between adjacent two full skirts 2, just increases the distance between adjacent two full skirts 2.Simultaneously secondary full skirt 3 open direction and full skirt 2 to open direction identical, the size of secondary full skirt 3 is less than the size of full skirt 1, also just increases the distance increased between full skirt 2 and secondary full skirt 3.Which increases the creepage distance of insulating sleeve, original insulating sleeve only has the creepage distance of 270mm, and the insulating sleeve of the present embodiment is after test, and its creepage distance can reach more than 380mm, thus improves fail safe.
Further, the opening angle of secondary full skirt 3 is less than the opening angle of full skirt 2, make secondary full skirt 3 different with the shape of full skirt 2, and the spacing distance between adjacent two full skirts 2 is more than or equal to 40mm, checking can increase the creepage distance of insulating sleeve further by experiment.
Further, full skirt 2 is provided with three, and secondary full skirt 3 is provided with two, and the shape of three full skirts 2 is identical with size, and the shape of two secondary full skirts 3 is also identical with size, and this is convenient to a large amount of manufacture.
As above-mentioned preferred, the height of full skirt is 20mm, and when the height of secondary full skirt is 20mm, the effect that its anti-on-slip is dodged is best.
Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
Claims (6)
