Description
Technical field
The present invention relates to a kind of adjustable disconnecting link bases of ultra-high voltage converter station valve hall.
Background technique
Gradually perfect with domestic extra-high voltage direct-current transmission engineering, ultra-high voltage converter station valve hall quantity is also with converter station
Increase and gradually increase.In valve hall grounding switch capital construction install period, switch mechanism with the pre-buried spiral shell in valve hall ground
Silk is connected, and valve hall ground base all needs to carry out Self-leveling laying before putting into operation.
Under normal circumstances, when valve hall direct-current wall bushing and valve tower equipment carry out producer or model is replaced, in valve hall
Grounding switch may be because that size matching problem needs to carry out displacement transformation, and domestic converter station and rapid growth and ran
When occurring in journey because of replacement equipment size change, grounding switch is displaced in valve hall.At this point, being spread before ground need to be destroyed
If Self-leveling, carry out ground excavation, built-in screw position is adjusted, install switch mechanism when need to dynamic/static contact it
Between disconnecting link stroke carry out precise measurement with guarantee it is disposable in place, the mechanism height i.e. secondary tune of disconnecting link stroke can not be carried out
It is whole, ground is carried out again later and Self-leveling is laid with, and the duration substantially needs two weeks, and ash caused by scene in the construction process
Dirt may pollute in the valve tower in valve hall, and for ultra-high voltage converter station, converter valve is equivalent to the heart of entire direct current artery,
Running environment is required high.The working environment of valve hall internal request is totally-enclosed, micro-positive pressure, with air-conditioning and ventilation, and
Valve tower deashing must work during annual overhaul when working.So if adjusting disconnecting link position with the method for excavating foundation
It sets, valve tower need to carry out inspection and cleaning after completion, also need to increase certain expenditure of time.
Summary of the invention
The object of the present invention is to provide a kind of adjustable disconnecting link bases of ultra-high voltage converter station valve hall, can be in a short time
Complete disconnecting link displacement change and height Traffic control system, thus meet in valve hall disconnecting link equipment because that can not resist factor that need to carry out position
Set mobile and height adjustment needs.
A kind of adjustable disconnecting link basis of ultra-high voltage converter station valve hall, its special feature is that: including being parallel to each other and
It is fixedly connected with integral lower layer's steel plate and upper layer steel plate by supporting rib, is equipped with through-hole on lower layer's steel plate thus and valve hall
Pre-embedded bolt in ground is fixedly connected, and on the upper layer, steel plate left and right side has several connecting holes, in the connecting hole
On lead screw is installed, the lead screw pass through grounding switch ontology base support and be threadedly coupled with the base support.
Wherein lower layer's steel plate and upper layer steel plate are identical rectangular slab, four angles and long side in lower layer's steel plate
Centre is respectively equipped with supporting rib, and supporting rib welds together with lower layer's steel plate and upper layer steel plate respectively.
The present invention provides the adjustable disconnecting link bases of a kind of " assembled " height, can not destroy valve hall ground and disconnecting link basis
In the case where, by the installation to the built-in screw of position before disconnecting link of the basis in the short time, can be held as linking carrier
The weight of entire switch mechanism ontology is carried, and moving contact of disconnecting link mechanism can be carried out according to grounding switch top stationary contact grease head highness high
Degree adjustment is to guarantee that dynamic/static contact can be contacted well.Adjustable height disconnecting link basis of the invention mainly uses special steel plate and adds
Work is the double-deck steel base, and the perforation of lower layer's steel plate is connected with the pre-embedded bolt on valve hall ground, plays fixed function.Upper layer steel plate is worn
Hole is connected with ground knife support, is fixed using the adjustable lead screw of sufficient intensity, plays displacement, support and adjustment effect.By this
The installation on the adjustable disconnecting link basis of " assembled " height can complete the translation installation that disconnecting link is fast and reliable in valve hall.
Detailed description of the invention
Accompanying drawing 1 is the structural representation of the present invention；
Attached drawing 2 is structural schematic diagram of the invention.
Specific embodiment
As shown in Figure 1, 2, it is basic including mutual with adjustable disconnecting link that the present invention provides a kind of ultra-high voltage converter station valve halls
It is fixedly connected with integral lower layer's steel plate 4 and upper layer steel plate 2 in parallel and by supporting rib 1, is equipped on lower layer's steel plate 4 logical
Hole has several connections in 2 left and right side of upper layer steel plate to be fixedly connected with the pre-embedded bolt in valve hall ground
Hole 3 is equipped with lead screw 5 on the connecting hole 3, the lead screw 5 pass through grounding switch ontology base support and with the pedestal branch
Frame is threadedly coupled.
Wherein lower layer's steel plate 4 and upper layer steel plate 2 are identical rectangular slab, in four angles of lower layer's steel plate 4 and length
The centre on side is respectively equipped with supporting rib 1, and supporting rib 1 welds together with lower layer steel plate 4 and upper layer steel plate 2 respectively.
The purpose of the invention is to can in valve hall disconnecting link equipment it is mobile and high because that can not resist factor that need to carry out position
When degree adjustment, passing through this assembled " the adjustable disconnecting link basis of height can be completed in a short time the displacement of disconnecting link and change and high
Traffic control system is spent, complete repairing work in time and electricity can be served in time for direct current main artery.
The technical solution adopted in the present invention is as follows:
The adjustable disconnecting link basis of this " assembled " height the double-deck steel is processed into using the 235B shape steel plate of 30 millimeters thicks
Basis, the perforation of lower layer's steel plate 4 are connected with the pre-embedded bolt in valve hall ground, play fixed function, the perforation of upper layer steel plate 2 and earthing knife-switch
Bracket is connected, and lead screw 5 is adjusted using intensity 8.8 and fixes, plays displacement, support and adjustment effect.It on this basis can be to knife
The height of lock is adjusted, with adaptation top static contact because caused by equipment size problem difference in height cause disconnecting link to be likely to occur
Formed too short or too long, height adjustable extent is about 200 millimeters.It in this way can be without destroying ground self-leveling and excavating ground
The situation decline disconnecting link retrofit work amount on basis is preferably minimized, and is substantially reduced the working hour of disconnecting link transformation and is ensured disconnecting link basis
That installs is solid and reliable, and ensure that improved grounding switch dynamic/static contact without perfect suitable in the case where changing size
Match.
The present invention is mainly supported by the double-layer plate of the 235B type of 30 millimeters thicks for being connected disconnecting link built-in screw and disconnecting link
Main body mechanism reaches the work of disconnecting link displacement as all wt of carrier carrying switch mechanism, and can adjust switch mechanism
Disconnecting link stroke of the length to be adapted between disconnecting link dynamic/static contact.The invention patent with processing, safely may be used by the quick, strength of materials
It leans on, install convenient, flexibility height, improve the advantages that construction reformation efficiency, environmental protection, the disconnecting link transformation work in valve hall can be completed in time
Make and guarantees that direct current system can put into operation in time.
