Abstract
The invention relates to electrical equipment, and particularly relates to an outdoor high-voltage through-wall bushing. The technical problem to be solved by the invention is to provide a through-wall bushing reducing contact resistance. The technical scheme is that the invention provides a novel through-wall bushing which comprises a conductor and an insulating layer from inside to outside. The insulating layer is externally wrapped by umbrella skirts. The two ends of the conductor stretch out of the insulating layer. The two ends of the insulating layer are provided with a voltage-equalizing cover respectively, and the middle part is provided with a flange. The conductor is flat, and the two ends are provided with connecting holes. According to the technical scheme, the conductor is flat, and the two ends are provided with connecting holes so as to be directly connected with other conductors without additional arrangement of conductive wire clamps. Therefore, the related components can be saved and contact resistance can be reduced.
Description
Technical field
The present invention relates to a kind of electric equipment, especially a kind of outdoor high-voltage wall bushing.
Background technology
High-voltage wall bushing is used for power distribution equipment and the High-Voltage Electrical Appliances of power station and electric substation, for wire through ground dummy board, wall or electrical appliance enclosure, supports that current-carrying part makes it over the ground or casing insulation.In the prior art, the conductor of wall bushing is all cylinder usually, all needs to install conductor wire clamp at the two ends of conductor, is connected again, so, necessarily increases the contact resistance of whole equipment by conductor wire clamp with other conductor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wall bushing reducing contact resistance.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of New type through-wall sleeve, comprise conductor and insulating barrier from inside to outside, described insulating barrier is wrapped with full skirt, the two ends of described conductor stretch out in outside insulating barrier, and grading shield is equipped with at the two ends of described insulating barrier, and flange is equipped with at middle part, described conductor is flat, and two ends are equipped with wiring hole.
Technique scheme, because conductor is flat, two ends are equipped with wiring hole, therefore just directly can be connected with other conductor, and not need to install conductor wire clamp in addition, both save relevant parts, can reduce contact resistance again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the preferred embodiments of the present invention are, a kind of New type through-wall sleeve, comprise conductor 1 and insulating barrier 2 from inside to outside, described insulating barrier 2 is wrapped with full skirt 3, and the two ends of described conductor 1 stretch out in outside insulating barrier 2, grading shield 4 is equipped with at the two ends of described insulating barrier 3, flange 5 is equipped with at middle part, and described conductor 1 is in flat, and two ends are equipped with wiring hole 6.
Claims (1)
