Abstract
The utility model provides a kind of 110kV switch touching bar device, and this device includes conducting rod, bolt, spacer sleeve, contact; Described contact is by the structure of sheet fabrication, and is connected with conducting rod by bolt, and on bolt, cover has spacer sleeve, to ensure the distance of two conductive walls on conducting rod respectively.What effect of the present utility model was that this tactile bar device adopts is bolt connecting mode, can meet structure instructions for use, can solve again the weld defect of above-mentioned existence, reduce loop resistance, improve the through-current capability touching rod.Contact in this device is formed by sheet fabrication, and the surface area that this kind of contact contacts with air is 0.058m
2, increase area of dissipation, be conducive to heat radiation.
Description
Technical field
The utility model relates to a kind of 110kV switch touching bar device, is applicable on the 110kV high voltage isolator in ultra-high-tension power transmission line.
Background technology
As shown in Figure 1, this device is made up of conducting rod 1 ＇, contact 2 ＇ current 110kV switch touching bar device; Contact 2 ＇ adopts welding manner to be connected with conducting rod 1 ＇.This kind of connected mode easily forms the defect such as pore, slag inclusion in commissure, and this kind of defect directly increases the loop resistance of conductor, reduces the through-current capability touching rod.The contact that current device uses is formed by the copper pipe processing of φ 50, and the surface area that this kind of contact contacts with air is 0.02m
2.The surface area that this contact contacts with air is little, is unfavorable for heat radiation, and then affects useful life.
Summary of the invention
For the problems referred to above, the utility model provides a kind of 110kV switch touching bar device, and this device both reduced loop resistance, improves and touches excellent through-current capability, in turn increases area of dissipation, be conducive to heat radiation.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of 110kV switch touching bar device, wherein: this device includes conducting rod, bolt, spacer sleeve, contact; Described contact is by the structure of sheet fabrication, and is connected with conducting rod by bolt, and on bolt, cover has spacer sleeve, to ensure the distance of two conductive walls on conducting rod.
Effect of the present utility model is:
1, loop resistance is reduced.What this novel tactile bar device adopted is bolt connecting mode, and this kind of mode can meet structure instructions for use, can solve again the weld defect of above-mentioned existence, reduce loop resistance, improves the through-current capability touching rod.
2, heat radiation is conducive to.Touching at present contact in bar device is formed by the copper pipe processing of φ 50, and in this device, contact is formed by sheet fabrication, and the surface area that this kind of contact contacts with air is 0.058m
2.Greatly increase and contact area of dissipation with air, be conducive to heat radiation.
Accompanying drawing explanation
Fig. 1 is former 110kV switch touching bar device schematic diagram;
Fig. 2 is 110kV switch touching bar device schematic diagram of the present utility model.
In figure:
1, conducting rod 2, bolt 3, spacer sleeve 4, contact
Embodiment
By reference to the accompanying drawings 110kV switch touching bar device structure of the present utility model is illustrated.
As shown in Figure 2,110kV switch touching head unit of the present utility model, this device includes conducting rod 1, bolt 2, spacer sleeve 3, contact 4; Described contact 4 is by the structure of sheet fabrication, and is connected with conducting rod 1 by bolt 2, and on bolt 2, cover has spacer sleeve 3, to ensure the distance of two conductive walls on conducting rod.
First 110kV switch touching bar device of the present utility model is utilize bolt connecting mode to replace welding connecting mode.This avoid the loop resistance increase phenomenon because weld defect causes, improve the through-current capability touching rod; Secondly this 110kV switch touching bar device is the contact 4 utilizing sheet fabrication, instead of the contact processed by copper rod, increases the area of dissipation contacted with air, is conducive to heat radiation.
