Abstract
The invention provides a strain tower drainage wire bracket which is characterized by comprising an inner pipe and an outer pipe which are movably matched in an inserting manner. The inner pipe and the outer pipe are respectively welded with one or more than one U-shaped bolt; a pressing plate and a nut are further matched with the U-shaped bolts; the other end of the inner pipe is welded with a mounting plate; and the other end of the outer pipe is welded with a connecting piece. A method for stabilizing a drainage wire by using the strain tower drainage wire bracket is characterized by comprising the following steps of: fixing the mounting plate at one end of the inner pipe on a cross arm at an electrified side of an insulator hanging bunch; utilizing the U-shaped bolts to fix the drainage wire on the bracket; and finally, mounting the connecting piece of the outer pipe on two connecting plate sag adjusting plates or an extending ring of an electrified part of the front part of an insulator pulling bunch of a strain tower. The strain tower drainage wire bracket is used for fixing the drainage wire so that the problems that the drainage wire swings in a wind environment, the distance between the drainage wire and an iron tower is small and the drainage wire is easy to discharge are solved, and the safe and reliable operation of a line can be guaranteed.
Description
Technical field
The invention belongs to T & D Technology field, particularly make the device and method that strain tower drainage thread is stable.
Background technology
Original 220KV line midline drainage adopts the mode of hanging string to have two kinds, and one twoly hangs string, and another kind singly hangs string.Strain tower of transmission line drainage thread, particularly singly hangs string drainage thread and swings excessive in strong wind atmosphere, with strain tower apart from little, easily causes line tripping power-off to steel tower electric discharge, causes economic loss to enterprise and society.
Summary of the invention
Swing in strong wind atmosphere to solve strain tower drainage thread, little with the distance of strain tower, cause drainage thread to discharge to strain tower, cause the problem of line tripping power outage, propose following technical scheme.
A kind of strain tower drainage thread support, its special character is that it comprises the movable inner and outer tubes coordinating grafting mutually, inner and outer tubes are respectively welded with the U-bolt of more than 1 or 1, pressing plate and nut is separately had to coordinate with U-bolt, at the other end welded and installed plate of interior pipe, in the other end welded connections of outer tube.
A kind of method using strain tower drainage thread bracket stable drainage thread, its special character the mounting panel of interior pipe one end is fixed on insulator to hang on the cross-arm of ribbon electricity side, again drainage thread is placed in U-bolt along rack surface, cover pressing plate, to screw on nut, drainage thread is stretching, from mounting panel end to outer tunnel end successively fastening nut, insulator to be observed hang string whether naturally droop when tightening the nut on outer tube, when insulator hangs string perpendicular to the nut tightened again during ground on outer tube, finally the connector on outer tube is arranged on strain tower insulator draw the two connecting plate sag adjustment plates at the anterior charged position of string or extend on ring.
Tool of the present invention has the following advantages:
Because strain tower drainage thread support of the present invention is made up of two sleeve pipes that activity coordinates mutually, can stretch, therefore, string can be hung according to insulator when fixing drainage thread and whether adjust perpendicular to ground the degree of depth that interior pipe inserts outer tube, like this, easy for installation, to save time, laborsaving.And because inner and outer pipes is movable connected structure, can stretch, therefore, it is possible to adapt to because of the change of natural conditions, as strong wind, severe cold, heat, swing or the relaxation causing drainage thread such as freezing.Use this strain tower drainage thread support to fix drainage thread, solve drainage thread and swing in strong wind atmosphere, with the problem of steel tower apart from little, easy electric discharge, line security reliability service can be ensured.
Accompanying drawing illustrates:
Fig. 1 is full sectional view, and Fig. 2 is vertical view, and Fig. 3 is partial enlarged drawing A-A, Fig. 4 is strain tower drainage thread support using state schematic diagram.
Embodiment
Embodiment, describes embodiment with reference to the accompanying drawings.
A kind of strain tower drainage thread support, it comprises movable interior pipe 4 and the outer tube 3 coordinating grafting mutually, interior pipe 4 welds two U-bolts 5, outer tube 3 welds 1 U-bolt 5, pressing plate 8 and nut 9 is separately had to coordinate with U-bolt 5, weld the mounting panel 6 it having installing hole 7 at the other end of interior pipe 4, weld the connector 2 with connecting ring 1 at the other end of outer tube 3.Mounting panel 6 adopts length 150 millimeters, wide 40 millimeters, thick 5 millimeters steel plate is made.Interior pipe 46 points of steel pipes are made, 6 meters long; Outward effective 1 inch steel pipe make, 1.2 meters long.The degree of depth that interior pipe 4 inserts outer tube 3 will be determined to resistance to two connecting plates at stretch-draw ribbon electricity position or the distance of prolongation ring 13 perpendicular to cross-arm during ground 11 end according to hanging when insulator string 12, is generally about 0.6 meter.Gap between interior pipe 4 and outer tube 3 is approximately 3 millimeters.In in figure, pipe 4 is large with the gap of outer tube 3, just clear in order to show.Spacing between three bolts 5 is 0.9 meter.
A kind of method using strain tower drainage thread bracket stable drainage thread, it the mounting panel 6 of interior pipe 4 one end is fixed on insulator to hang on the cross-arm 11 of ribbon electricity side, again drainage thread 15 is placed in U-bolt 5 along rack surface, cover pressing plate 8, to screw on nut 9, by stretching for drainage thread 15, from mounting panel 6 end to outer tube 3 end successively fastening nut 9, insulator to be observed when tightening the nut 9 on outer tube 3 and hang no on string 12 naturally drooping, when insulator hangs string 12 perpendicular to ground, determine the length of interior pipe to the two connecting plate sag adjustment plates at resistance to stretch-draw ribbon electricity position or the distance of prolongation ring 13 according to cross-arm 11 one end, if oversize, after reserved 0.6 meter, it is sawed-off, insert afterwards in outer tube 3, the degree of depth inserted in outer tube 3 is 0.6 meter, at this moment the nut 9 on outer tube 3 is tightened again, finally the connector 2 on outer tube 3 is arranged on strain tower insulator to draw on the prolongation ring 13 of string front portion.In figure, sequence number 10 is strain tower, 14 is be not stuck in the drainage thread in U-bolt 5.
Strain tower drainage thread support is used to fix drainage thread, by U-bolt, drainage thread is rack-mount, drainage thread is held up, without radian, thus increase the distance of drainage thread and strain tower closest approach, reach the requirement of safe operation, ensure that line security runs.
