Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, it is only used for explaining
The present invention, and be not considered as limiting the invention.
Fig. 1 is the floor map of the embodiment of the present invention, high for 500kV buses in a 500kV transformer station shown in Fig. 1
The deployment scenarios of shunt reactor 1 are pressed, by the position of 500kV bus high-voltage shunt reactors fire wall 8 and 500kV earthed switches
4 keep on one wire, it is preferable that the position of bus high-voltage shunt reactor fire wall 8 and earthed switch 4, breaker 5 and every
Pass 6 is left to keep on one wire；A 500kV support insulator 3 is respectively placed on every face fire wall 8 to be grounded as 500kV
Transition connection between switch 4 and bus high-voltage shunt reactor 1.Earthed switch 4 and high-voltage parallel reactance can so be reduced
Wire connection distance between device 1, so as to reduce to high-voltage shunt reactor sleeve pipe 2 and the terminal board of earthed switch 4
Mechanical load.
Fig. 2 shows the sectional schematic diagram of the embodiment of the present invention.Install additional after support insulator 3, not only reduce on fire wall 8
Wire connects distance between earthed switch 4 and high-voltage shunt reactor 1, also improves height of the wire away from lower section transport routes 9
Degree, is particularly suitable for use in regional height above sea level higher and produce powered distance correction.
By taking the 500kV transformer stations of Wuchuan as an example, the parameters data shown in Fig. 1 and Fig. 2 are taken from the transformer station.
Wuchuan 500kV transformer stations height above sea level is 1670 meters, according to《High voltage distribution installation designing technique code (DL/T5352-2006)》
Middle regulation, during 500kV equipment conveyings, its equipment gabarit need to be modified to 5050mm to without distance between blocking live part.From Fig. 2
In as can be seen that the distance of 500kV earthed switches 4 to support insulator 3 is 11500mm, support insulator 3 and high-voltage parallel electricity
The distance of anti-device 1 is 3000mm, therefore, and 500kV earthed switches 4 to the actual range of high-voltage shunt reactor 1 are 3000mm+
11500mm=14500mm.But, by increasing support insulator 3,500kV earthed switches 4 to high-voltage parallel on fire wall 8
The distance of reactor 1 is reduced to 11500mm.
Conducting wire sag 7 between support insulator 3 and 500kV earthed switches 4 is chosen for 800mm, passes through wire tension meter
Draw, the mutual conductance line load is 3000N.As shown in figure 1,500kV support insulators 3 are to high-voltage shunt reactor sleeve pipe 2
Distance is 5420mm, and the conducting wire sag between support insulator 3 and high-voltage shunt reactor sleeve pipe 2 is chosen for 500mm, by leading
Line pulling force is calculated, and the mutual conductance line load is 800N, respectively less than high-voltage shunt reactor sleeve pipe 2, support insulator 3, ground connection
4 terminal board upper limit mechanical load 4000N are switched, design requirement is met.
Band electrical distance verification is carried out for Square wire on the transport routes 9 of the embodiment, from figure 2 it can be seen that pillar
The height of wire is that the height of fire wall 8 subtracts wire arc again plus the height of support insulator 3 between insulator 3 and earthed switch 4
Hang down 7 i.e. 5700mm+5000mm-800mm=9900mm, and this highly adds to the correction tape electrical distance of equipment gabarit more than wire and set
Standby gabarit transportation clearance is 5050mm+4000mm=9050mm, meets design discipline requirement.
As the contrast with technical solution of the present invention, Fig. 3 shows prior art median generatrix high-voltage shunt reactor 1 ' often
The sectional schematic diagram of the outdoor arrangement of rule.In the comparative example, as shown in figure 3, high-voltage shunt reactor 1 ' and earthed switch 4 ' it
Between be directly connected by wire, and support insulator 3 is set not on fire wall 8 ', the arrangement of following transformer station still mainly adopts
With the supplemental characteristic of Wuchuan 500kV transformer stations.As shown in figure 3,500kV earthed switches 4 ' to the distance of high-voltage shunt reactor 1 ' is
14500mm, only when conducting wire sag 7 ' is chosen for 1500mm, the mutual conductance line load could meet earthed switch terminal board
Mechanical load 4000N requirement.And band electrical distance verification now is carried out for the wire above transport routes, the height of wire is
Bus high-voltage shunt reactor sleeve pipe 2 ' highly subtracts the 10050mm-1500mm=8550mm of conducting wire sag 7 ' i.e., and this is highly less than
Wire is 5050mm+4000mm=9050mm plus equipment gabarit transportation clearance to the correction tape electrical distance of equipment gabarit, now
Band electrical distance can not meet design discipline requirement to the wire over the ground.
In summary, key point of the invention is by the position of 500kV bus high-voltage shunt reactor fire walls and 500kV
Earthed switch is kept on one wire, and a 500kV support insulator is respectively placed on every face fire wall and is opened as 500kV ground connection
Close the transition connection between high-voltage shunt reactor.Set by this, effectively reduce 500kV bus high-voltage shunt reactors
To the lead load between earthed switch, and solve the band electrical distance check problem of road below the lead.
It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferable
The present invention is described in detail embodiment, it will be understood by those within the art that, can be to technology of the invention
Scheme is modified or equivalent substitution, and without departing from the spirit and scope of technical solution of the present invention, it all should cover in this hair
Among bright right.
