The two neighboring smoothing reactors are connected in series through the tubular conductor. The lightning arresters are connected to the smoothing reactors in parallel. The lightning arresters connect with the lightning arresters through the connection tools. Special tools used for using with the tubular conductors in a mating manner for the connection of wiring terminal boards of the dry-type smoothing reactors includes a telescopic wire clamp connecting an electric reactor support and the tubular conductor, a bridging flexible conductor connecting the wiring terminal boards and the tubular conductor, and a grading ring.
Description
Technical field
The utility model relates to a kind of connected mode between ultra high voltage current conversion station smoothing reactor, particularly adopts the connected mode of tubular conductor between ultra high voltage current conversion station dry smoothing reactor.
Background technology
Extra-high voltage direct-current transmission engineering transmission capacity is very big, and is very high to reliability requirement, and smoothing reactor is as the visual plant in the current conversion station, and its operational reliability will have influence on the reliability of DC transmission engineering.Advantages such as dry type is flat anti-to have the redundancy height, cost is low, safe, noise is little and operation maintenance is convenient, the ultra high voltage current conversion station generally recommends to adopt dry smoothing reactor.Owing to be in series by two or above reactor more than the restriction of device fabrication level and transportation condition, ultra high voltage current conversion station smoothing reactor.The electric pressure of ultra high voltage current conversion station is than higher, and the main insulation of dry smoothing reactor is provided by post insulator, and flat anti-tens meters high insulators of employing that need support, and the dynamic stability of equipment is had higher requirement.Between the dry smoothing reactor the tubular conductor ways of connecting of a kind of employing is arranged at present, but through post insulator tubular conductor is supported between two flat resisting, not only increased investment, and increased workload for the operation and the maintenance in later stage.Therefore, be necessary the connection between the smoothing reactor is further studied, propose a kind of reliable, convenient and solution attractive in appearance.
Summary of the invention
The purpose of the utility model is to provide a kind of actual requirement of engineering that can satisfy, and is used for connected mode simple and reliable between the dry smoothing reactor.
For achieving the above object, the utility model takes following technical scheme to be achieved:
Adopt tubular conductor connect structure between a kind of ultra high voltage current conversion station smoothing reactor, comprise smoothing reactor, lightning arrester, tubular conductor and be connected gold utensil; Said adjacent two smoothing reactors are parallel with lightning arrester through tubular conductor series connection on each smoothing reactor; Said lightning arrester is parallelly connected with smoothing reactor through connecting gold utensil.
Said smoothing reactor is provided with carriage, and carriage is connected with tubular conductor through connecting gold utensil.
Said connection gold utensil is flexing line clamp, the cross-over connection flexible conductor that is connected smoothing reactor terminal board and tubular conductor that connects carriage and tubular conductor, the grading ring that improves smoothing reactor terminal board place electric field strength.
Said cross-over connection flexible conductor one end is connected with the smoothing reactor terminal board, and the other end is connected with tubular conductor.
The utility model advantage is: smoothing reactor adopts tubular conductor to connect, and helps improving corona inception voltage, installs and overhaul simple, easy to connect, reliable and attractive in appearance.Adopt special gold utensil to connect, do not need between the tubular conductor to support with post insulator again, local use flexible conductor cross-over connection, this flexible connection mode can alleviate reactor under earthquake sheet and other power effect during the generation displacement to the effect of tubular conductor.
Description of drawings
Fig. 1 dry smoothing reactor connects vertical view;
Fig. 2 dry smoothing reactor connects front view;
Fig. 3 dry smoothing reactor is connected detail drawing with tubular conductor;
Wherein: 1 is that smoothing reactor, 2 is that lightning arrester, 3 is that tubular conductor, 5 is that apparatus body terminal board, 6 is that carriage, 7 is the cross-over connection flexible conductor for connecting gold utensil, 4.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail:
A tubular conductor that satisfies the ampacity requirement, two covers are used for the special gold utensil that the dry smoothing reactor terminal board is connected with tubular conductor is matching used, and specifically connected mode is as illustrated in fig. 1 and 2.Wherein tubular conductor dbus is crossed and is connected gold utensil and be installed on the carriage of reactor winding body, adopts the division flexible conductor to be connected between the terminal board on the reactor and the tubular conductor, and the connection details is as shown in Figure 3.
As depicted in figs. 1 and 2, two dry smoothing reactor all adopt insulator to support, and receive the influence of factors such as short-circuit electromotive force, and the centre distance between two reactors is about 15 meters, and the distance between the terminal board is about 10 meters.Between the two if adopt flexible conductor to connect; For satisfying ampacity and requirement such as anticorona, need to adopt many division flexible conductors, receive the influence of gravity bigger and divide flexible conductor to the loading ratio of reactor terminal board more; And there is hidden danger in the reactor winding body to reactor than higher during long-time running.
As shown in Figure 3, the utility model is crossed tubular conductor dbus on the carriage that special gold utensil is fixed in reactor winding, bears the gravity of bonding conductor with carriage, and adopts expansion joint between tubular conductor and the carriage.The reactor terminal board adopts short division flexible conductor to be connected with tubular conductor; Also disposed grading ring here, improved the electric field of junction, this special connected mode has combined to flexibly connect and rigidly connected advantage; Make the CURRENT DISTRIBUTION on the conductor more even; Improved the corona inception voltage of junction simultaneously, installation and maintenance are all very convenient, and attractive in appearance.In addition, this connected mode can alleviate reactor earthquake sheet and other power effect down during the generation displacement to the active force of connecting line.The reactor connecting line does not need post insulator to support, and has saved construction investment.
Above content is to combine concrete preferred implementation to further explain that the present invention did; Can not assert that embodiment of the present invention only limits to this; Those of ordinary skill for technical field under the present invention; Under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to the present invention and confirm scope of patent protection by claims of being submitted to.
