Abstract
The utility model discloses a pillar insulator comprising an insulator body and a holding device with a neck groove; and the holding device is provided with an outward opening from the neck groove. As the pillar insulator adopts the technical proposal, the holding device is provided with the outward opening from the neck groove; a ring-shaped closed structure of the existing installation manner is changed; the formation of a toroidal magnetic field passage is avoided; the wire insulation performance is protected; and the structure is simple, and the installation is convenient.
Description
Technical field
The utility model relates to a kind of post insulator.
Background technology
Electric power system customary insulation in power transmission and distribution is supported high voltage transmission line, fixed forms such as common metal coiling between insulator and the lead, anchor ear, U type cover plate.Usually aforesaid way is considered intensity, situation such as anti-aging, the general utensil of metal material that adopts comes the clamping lead, because this kind mode can cause forming the toroidal magnetic field path near fixing point, the temperature of this part on the insulated conductor is raise, thereby it is aging to quicken wire insulation, the insulating barrier be full of cracks, even cause the serious consequence that punctures the direct conducting electric leakage in back.Because the formation of toroidal magnetic field path also can cause increasing current loss.Adopting the mode of metal coiling also to need the workmen to possess certain experience and skill, is not very convenient in actual installation.
The utility model content
Technical problem to be solved in the utility model provides a kind of toroidal magnetic field path of avoiding and forms the post insulator of guardwire insulation property.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: post insulator, comprise insulator body and clamping device with wire casing, and described clamping device has one by the outside opening of wire casing.
Concrete, described clamping device comprises support and depression bar, described support is fixed in described insulator body upper end, described support is provided with second wire casing, described depression bar is provided with first wire casing corresponding with described second wire casing, described support and depression bar are fixed at an end of depression bar, leave opening at the other end of depression bar.
Preferably, described depression bar has two, and the staggered both sides of being fixed in described second wire casing are so that clamping is stable.
Concrete, described clamping device comprises support and is located at two clamping parts on the support, leaves opening between two clamping parts, and the space between the staggered barb that is provided with in described two clamping part ends, two barbs forms a wire casing with described open communication.
Further, described insulator body and clamping device are structure as a whole.
Preferably, described support is a round tray, so that processing and use, and make product attractive in appearance.
The utility model is owing to adopted technique scheme; described clamping device has one by the outside opening of wire casing; change the ring seal structure of existing mounting means, avoided the formation of toroidal magnetic field path, played the effect of guardwire insulation property and simple in structure, easy for installation.

Embodiment
Illustrated in figures 1 and 2 is the utility model post insulator execution mode one, comprise insulator body 1 and clamping device 2, described clamping device 2 comprises support 21 and depression bar 22, described support 21 is fixed in described insulator body 1 upper end, described support 21 is provided with second wire casing 31, described depression bar 22 is provided with first wire casing 32 corresponding with described second wire casing 31, and described support 21 is fixed at an end of depression bar 22 with depression bar 22, leaves opening 4 at the other end of depression bar 22.Described depression bar 22 has two, the staggered both sides of being fixed in described second wire casing 31.
During installation, earlier described insulator body 1 is fixed on the brandreth 6, semi-cylindrical hill and described insulator body 1 clamping of described support 21 by being located on support 21 lower ends fixed with nut after lead can being put into behind second wire casing 31 of support 21 respectively the installing hole that double-screw bolt with two depression bar 22 1 ends partly inserts support 21 both sides at last.
Fig. 3 is to Figure 7 shows that the utility model post insulator execution mode two, comprise insulator body 1 and clamping device 2, described insulator body 1 and clamping device 2 are by being threaded, described clamping device 2 upper surfaces are sphere, be provided with opening 4 at the sphere top, described clamping device 2 comprises support 21 and two clamping parts 23 being located on the support 21, leave opening 4 between two clamping parts 23, the staggered space that is provided with between 231, two barbs 231 of barb, described two clamping part 23 ends forms a wire casing 3 that is communicated with described opening 4.As shown in Figure 6, the zone that dotted line surrounded is barb 231 positions, and as shown in Figure 7, long straight conductor 7 can be put between two clamping parts 23 by opening 4, and rotating and clamping device 2 then, this long straight conductor 7 can be snapped in two barbs 231 times.
Further, described insulator body 1 and clamping device 2 can be integrative-structures.
By as can be seen above-mentioned; the clamping device 2 of two execution mode B-C post insulators all has one by the outside opening 4 of wire casing 3; change the ring seal structure of existing mounting means, avoided the formation of toroidal magnetic field path, played the effect of guardwire insulation property.
