Abstract
The utility model relates to a high voltage transmission lines keeps apart strutting arrangement should keep apart the eyelidretractor and include mounting substrate, support bar and connecting bolt, and the support bar passes through connecting bolt to be installed on mounting substrate, the utility model has the advantages that: simple structure is practical, utilizes oval groove can adjust the length and the orientation of each support bar in a flexible way, and the expansibility is strong, and the operation is supported in the isolation that is particularly suitable for a plurality of high -pressure cables, and almag light in weight, intensity height, corrosion -resistant are used to the material, are fit for open -air high altitude construction, long service life.
Description
Technical field
The utility model relates to a kind of power transmission equipment, is specifically related to high-tension line isolation bracing or strutting arrangement.
Background technology
For ultra-high-tension power transmission line, it is necessary to limit the distance between cable according to the size of transmission voltage, to prevent arc-over, affect the safety of power transmission. Existing cable shield retaining is generally hexagonal folder sheet, and the size of this folder sheet is completely fixed, and very flexible, restricted application, material resistance to compression and erosion resistance are poor, easy aging distortion.
Application number is a kind of multipurpose high-pressure cable shield retaining of the patent disclosure of 201510222450.X, in use there are 2 weak points, one is connect to regulate part to be unfavorable for that Fast Installation regulates more, two is that the half open fixed card ring of " C " font is unfavorable for installing fixing isolation cable, easily departs from when cable swings by strong wind.
Summary of the invention
Main purpose of the present utility model solves the technical problem existing for prior art, thus provides high-tension line isolation bracing or strutting arrangement.
The technical solution adopted in the utility model is: high-tension line isolation bracing or strutting arrangement, comprise installation base plate, multiple support bar and joint bolt, support bar is arranged on installation base plate by joint bolt, described installation base plate is provided with some oblong slots radially, one end of described support bar is provided with boss, boss is provided with connecting screw hole, the other end is provided with isolation set collar, isolation set collar is in the shape of a spiral, it is circumferentially provided with screw, being provided with tightening screw in screw, the boss of support bar is arranged in the oblong slots of installation base plate.
As the utility model preferred embodiment, described installation base plate and support bar are one-time formed aluminum magnesium alloy component.
The utility model has following useful effect compared with prior art: simple and practical, utilize the oblong slots can the length of each support bar of flexible and direction, extendability is strong, the isolation being particularly suitable for multiple high voltage cable supports operation, material uses that aluminum magnesium alloy weight is light, intensity height, corrosion-resistant, it is applicable to outdoor working aloft, it may also be useful to the life-span is long.
Accompanying drawing explanation
Fig. 1 is connection structural representation of the present utility model,
Fig. 2 is the sectional view of Fig. 1,
Fig. 3 is the structural representation of support bar.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made more explicit defining.
As shown in Figure 1 to Figure 3, high-tension line isolation bracing or strutting arrangement, comprise installation base plate 1, four support bars 2 and joint bolt 3, this installation base plate 1 is provided with eight oblong slots 11 radially, one end of this support bar 2 is provided with boss 21, boss 21 is provided with connecting screw hole, the other end is provided with isolation set collar 22, isolation set collar 22 is in the shape of a spiral, it is circumferentially provided with screw, being provided with tightening screw 23 in screw, the boss 21 of support bar 2 is arranged in the oblong slots 11 of installation base plate 1, is connected by joint bolt 3.
This installation base plate 1 and support bar 2 are one-time formed aluminum magnesium alloy component.
During use, when staff installs high voltage cable, each cable is inserted in the isolation set collar 22 of support bar 2 respectively, tightens tightening screw 23, then utilize joint bolt 3 to be fixed in the oblong slots 11 of installation base plate 1 by support bar 2, like this each cable is kept apart. In addition, oblong slots 11 is utilized, it may also be useful to person can regulate extrusion and the angle of each support bar 2, to adapt to the distribution of various different cable.
Being not limited to this, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim book limits.
