Description
Technical field
This utility model belongs to power industry hardware structure, especially one and prevents overhead transmission line L-type list from insulating
Substring falls the hardware structure of string.
Background technology
Carry out 500kV and the single insulator string of above multiple-loop line AC and DC overhead transmission line L-type pendency changes double string insulation
Subjob special project project is to reinforce for prevent single insulator string from falling major safety risks that power system brings by string
Special operation, we are fairly perfect to carry out the instrument reinforced, and in whole operating process, first remove the insulation of former stress
Substring, then remove the main material of hanging point, then install should design hardware, recover the main material of hanging point again, again insulator chain carried out
Assemble, be accomplished by substantial amounts of manpower, standby redundancy and complex work flow chart here.At present on multiple-loop line alive circuit
Carry out and when singly changing double cropping industry, need 6 staff to lead on-line operation at tower simultaneously, easily occur the major safety risks of string,
And former hardware cannot be used to reinforce.
Summary of the invention
This utility model gold utensil is on 500kV and above multiple-loop line AC and DC overhead transmission line, carries out L-type and hangs
Single insulator string that hangs down changes double insulator string and works, and its simple in construction is easy to use.When high-altitude circuit carries out upkeep operation, main
Body draw-in groove is directly fixed on above the main material of cross-arm hanging point, is connected hanging point position not acceptor's material, original design remaining with tower material by bolt
Give over to the restriction in industry hole, can general, mounting process is easy, quick.Do not change former set any electric equipment compartment away from.Construction is made to compare appearance
Easily, thus also mitigate the intensity of personal height operation, improve working performance.
Hardware of the present utility model, is especially adapted for use at multiple-loop line AC and DC Line technology transformation spare unit standby
Part aspect.
This utility model is according to 500kV and above multiple-loop line AC and DC overhead transmission line L-type pendency single string suspension side
The assembling figure of formula and insulator chain, carries out 500kV and the single string of above multiple-loop line AC and DC overhead transmission line L-type pendency is exhausted
Edge changes the hardware design that double insulator string operation is special.
The purpose of this utility model is achieved by the following technical solution.
1, a kind of overhead transmission line L-type pendency single falsification double string hardware, it is characterised in that main body is set to rectangle
Body, offer in main body front hanging hole for insulator chain or be connected gold utensil connect, be arranged with connection in main body two sides
Arm, this linking arm is less than principal length, is provided with a draw-in groove, is positioned at the side of main body on the connecting arm between linking arm and main body
Direction offers connecting hole, is provided with screw thread in connecting hole, is fixed on tower material by hardware by bolt.
This utility model draw-in groove is directly fixed on above the main material of cross-arm hanging point, do not change former set any electric equipment compartment away from.
This utility model is connected hanging point position not acceptor's material, the restriction in original design remaining operation hole by bolt with tower material,
Can general, mounting process is easy, quick.
The beneficial effects of the utility model are:
1, double working time shortening amount is singly changed
The working time of Dan Gaishuan shortens 120 minutes.
, reduce person works's risk
Many times of alive circuit with carry out on tower circuit singly change double cropping industry time；Inherently reduce the work of work high above the ground personnel
Making operation and physical demands, falling from high altitude, be in highfield operation equivalent risk for a long time, final reduction feels electrical verification and particle flux pair
Staff's physiological hazard and labor intensity, put forward efficiency operation efficiency, shorten power off time.
, save interruption maintenance put into personnel amount
Carry out on multiple-loop line alive circuit at present and when singly changing double cropping industry, need 6 staff simultaneously on tower wire
Operation, this courseware will solve this problem, will be directly reduced to 2 by 6 carrying out operating personnel when singly changing double cropping industry every time
Name staff gets final product complete operation, and 6 people carry out operation simultaneously and also to shorten the working time of nearly 120 minutes than ever.
Accompanying drawing explanation
Fig. 1 is this utility model broken section structural representation;
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
See Fig. 1, Fig. 2, a kind of overhead transmission line L-type pendency single falsification double string hardware, it is characterised in that main body 1
Be set to cuboid, offer in main body 1 front hanging hole 2 for insulator chain or be connected gold utensil connect, in main body 1 two sides pair
Claiming to be provided with linking arm 3, this linking arm 3, less than main body 1 length, is provided with a draw-in groove 4, at linking arm between linking arm 3 and main body 1
The side surface direction being positioned at main body 1 on 3 offers connecting hole 5, is provided with screw thread, is fixed by hardware by bolt in connecting hole 5
On tower material.
This utility model draw-in groove is directly fixed on above the main material of cross-arm hanging point, do not change former set any electric equipment compartment away from.
This utility model is connected hanging point position not acceptor's material, the restriction in original design remaining operation hole by bolt with tower material,
Can general, mounting process is easy, quick.
