Description
Technical field
The invention belongs to high-tension electricity T & D Technology field, particularly relate to a kind of method that can improve 220kV GIS device disconnecting link ground cutter deciliter reliability.
Background technology
At present, in electric power system, new 500kV and 220KV transformer station of throwing extensively adopts HGIS and GIS device (HGIS: hybrid power distribution equipment, GIS: gas insulated combined electric appliance equipment), different from traditional open equipment, in HGIS and GIS device, the main equipment of circuit breaker, isolating switch, grounding switch and transmission mechanism are all arranged in closed container.Operations staff, when operating equipment, by the run location of the position indicating device (deciliter indicating device) and supervisory control system judgment device of checking primary equipment, and can only cannot check the contact condition of contact intuitively.Simultaneously due to the seal of HGIS and GIS device, the phenomenon such as overheated that cannot find to cause because of poor contact of contacts by the mode of thermometric.Therefore, be difficult to equipment point, close reliability assess accurately.On the other hand, because the reliability of HGIS and GIS device is higher, seldom carry out overhauling, locating operations such as lacking, thus cause the walk accuracy of operations staff to the position indicator pointer of the mechanical pointer of HGIS and GIS device insensitive, accurately cannot judge whether contact that is quiet, moving contact puts in place.
By known to the comprehensive analysis of 220kV and 500kV disconnecting link/ground cutter deciliter principle and position indicating device:
A deciliter instruction for 1.500kV HGIS disconnecting link/ground cutter adopts deciliter direction board and connecting rod position to limit and jointly indicates, and whether the closing position accurately can expressing disconnecting link/ground cutter completely puts in place.
A deciliter position instruction for the disconnecting link/ground cutter of 2.220kV GIS uniquely represents by means of only position indication dial plate.Dial plate is designed to pointer and represents with a conjunction point position color region, and its pointer is connected with driving the crank axle of disconnecting link/ground cutter moving contact, is rotated, and then express the physical location of disconnecting link/ground cutter by the pointer rotarily driving position indicating device of crank axle.
When 220kV GIS device disconnecting link/ground cutter is in co-bit, the pointer of position indicating device is only positioned at the top of red area, and scale does not express the concrete condition of co-bit accurately.In view of few operability (the rare dynamic property of equipment) of 220kV equipment, from the dial plate of position indicating device, operations staff is single accurately cannot judge that whether the co-bit of disconnecting link/ground cutter is reliable.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of method that can improve 220kV GIS device disconnecting link ground cutter deciliter reliability.
In order to achieve the above object, the method that can improve 220kV GIS device disconnecting link ground cutter deciliter reliability provided by the invention comprises the following step carried out in order:
Step one, S01 stage of switch-on/off indicator scale is set: under the sufficiently closed state of power switchgear, position corresponding to switch-on/off indicator pointer arranges closing position scale; Under the state that power switchgear fully disconnects, position corresponding to switch-on/off indicator pointer arranges open position scale;
Step 2, set up S02 stage of indicator scale photo data: the photo data setting up switch-on/off indicator under the photo data of switch-on/off indicator under "on" position and gate-dividing state, so that the comparison in later stage and repairing;
The S03 stage of step 3, supervision divide-shut brake effect: when each breaking-closing operating, by the overlap situation of divide-shut brake position scale with switch-on/off indicator pointer, whether assessment breaking-closing operating puts in place completely, guarantees that divide-shut brake is fully reliable;
In the S04 stage of step 4, adjustment indicator scale deviation: when each breaking-closing operating completes, check whether divide-shut brake position scale occurs deviation, then carry out correction of deviation by adjustment divide-shut brake position scale if there is deviation; Need to set up new indicator scale photo data after adjustment divide-shut brake position scale;
Step 5, the S05 stage made regular check on: the switch-on/off indicator pointer of all power switchgears and divide-shut brake position scale are made regular check on, avoids because weather conditions cause label loss situation;
The S06 stage of service indicators scale when step 6, maintenance: utilize inspection operation to safeguard switch-on/off indicator pointer and divide-shut brake position scale, test and revise.
In the S01 stage, described power switchgear mainly comprises circuit breaker, isolating switch and grounding switch in HGIS and GIS device.
In the S01 stage, the described method arranging closing position scale is: under "on" position, and at the outer surface of indicating device dial plate, the head of corresponding indicator pointer and afterbody, arrange the closing position scale overlapped with indicator pointer center line; The described method arranging open position scale is: under gate-dividing state, and at the outer surface of indicating device dial plate, the head of corresponding indicator pointer and afterbody, arrange the open position scale overlapped with indicator pointer center line.
In the S03 stage, the concrete grammar whether described assessment breaking-closing operating puts in place is completely: whether the first step overlaps to judge according to indicator pointer and corresponding scale completely; Second step confirms further according to the further feature of equipment and systems axiol-ogy information again; If the result disunity that above-mentioned two steps judge, then illustrate that deviation appears in indicator scale, need to adjust in the S04 stage.
The result of use that can improve the method for 220kV GIS device disconnecting link ground cutter deciliter reliability provided by the invention: after closing position scale is set, whether divide-shut brake puts in place intuitively can to judge disconnecting link significantly, avoid disconnecting link mechanical location divide-shut brake not in place, but the conversion of secondary auxiliary contact puts in place, the misoperation put in place is changed in supervisory control system instruction, effectively can avoid owing conjunction due to disconnecting link and cause disconnecting link contact heating defect.
