Abstract
The utility model relates to an iron core drawstring shielding structure for a large transformer, belonging to the technical field of a transformer. The technical scheme adopted by the utility model is as follows: the iron core drawstring shielding structure comprises a shielding sleeve (1), an insulation sleeve (2), a fastener (4) and a drawstring (7), wherein the shielding sleeve is fixed on the drawstring through the fastener, and the insulation sleeve is arranged outside the shielding sleeve. According to the utility model, the fastener is a bolt and nut structure, one end of the drawstring is provided with a screw rod, the shielding sleeve is fixed on the drawstring through the bolt and nut structure, an open hole is formed in the end of the shielding sleeve, a threaded hole is formed in the end of the screw rod of the drawstring, and the insulation sleeve is bound on the drawstring through a cotton rope. The utility model has the positive effects that the size of an oil tank does not need to be specially enlarged, the shielding sleeve is installed through the screw rod at the end of the drawstring, and the electric filed at the sharp corner of the drawstring is equalized, so that the problem of the local discharge of the drawstring can be effectively avoided, and the transformer can be ensured to safely and reliably operate.
Description
Technical field
The utility model relates to a kind of iron core drawstring shielding construction of high-power transformer, belongs to the transformer technology field.
Background technology
Fast development along with power industry; The transformer rated capacity constantly increases; For the increase of the volume of control transformer, the distance between just must the control transformer inner structural members, if but the drawstring that goes between etc. distance can not fully satisfy electric requirement; The non-uniform electric field at drawstring screw rod place will make oil puncture, produces partial discharge phenomenon.
The utility model content
The purpose of the utility model provides a kind of iron core drawstring shielding construction of high-power transformer, under the situation that does not increase volume of transformer, guarantees the safe and reliable operation of transformer, solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: a kind of iron core drawstring shielding construction of high-power transformer, comprise radome, insulating case, securing member, drawstring, and radome is fixed on the drawstring through securing member, and insulating case is arranged on the radome outside.
Said securing member is a bolt nut structure, and an end of drawstring is provided with screw rod, and radome is fixed on the drawstring through bolt nut structure, the perforate of radome end, and the screw rod end of drawstring is provided with screw, and insulating case is tied up on drawstring through cotton cord.
The good effect of the utility model: need not specially increase the volume of fuel tank, utilize the screw rod of drawstring end that radome is installed, the electric field of even drawstring sharp corner, thus effectively avoided drawstring place partial discharge problem, guarantee the safe and reliable operation of transformer.
Description of drawings
Accompanying drawing 1 is the utility model embodiment sketch map;
Among the figure: radome 1, insulating case 2, securing member 4, drawstring 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
A kind of iron core drawstring shielding construction of high-power transformer comprises radome 1, insulating case 2, securing member 4, drawstring 7, and radome is fixed on the drawstring through securing member, and insulating case is arranged on the radome outside.Said securing member is a bolt nut structure, and an end of drawstring is provided with screw rod, and radome is fixed on the drawstring through bolt nut structure, the perforate of radome end, and the screw rod end of drawstring is provided with screw, and insulating case is tied up on drawstring through cotton cord.
Claims (2)
1. the iron core drawstring shielding construction of a high-power transformer is characterized in that comprising radome (1), insulating case (2), securing member (4), drawstring (7), and radome is fixed on the drawstring through securing member, and insulating case is arranged on the radome outside.
