Based on the same inventive concept, this application provides the corresponding movement based on bypass Live line maintenance method of embodiment one is negative Lotus turns the embodiment for method, detailed in Example two
Embodiment two
Second embodiment of the invention provides a kind of moving load based on bypass Live line maintenance method and turns for method, packet It includes:
S1, by answering racing that power distribution network high voltage cable is connected with low pressure cable for the high-low voltage leads in vehicle, make to meet an urgent need Turn to be in parallel connection in short-term for vehicle and distribution transformer to be replaced;
S2, disconnect distribution transformer height push type broach between, so that distribution transformer is exited distribution network system, the distribution more renewed Transformer repairs it;
S3, between closing height push type broach, make that racing is answered to be in parallel connection again for vehicle and distribution transformer, racing is answered in disconnection For the high and low voltage switch of vehicle, make that racing is answered to exit distribution for vehicle.
Specifically, transformer to be replaced, that is, old transformer is denoted as No. 1 transformer, new transformer is denoted as No. 2 transformers, other Transformer in the system of road is denoted as No. 3 transformers;
No. 1 transformer, No. 2 transformers, No. 3 parallel operation of transformers need to meet condition: winding connection group is identical;No-load voltage ratio Identical allowable error ± 0.5%;Identical allowable error ± 10% of impedance voltage;Capacity ratio is usually no more than 3:1.
Practical operation specifically includes 3 stages, is preparation stage, sessions and ending phase respectively:
Preparation stage: according to the field position of No. 1 transformer, crane and No. 3 transformers being parked on rational position, inspection It looks into crane and whether answer racing safe and reliable for the ground under vehicle, while checking whether crane leg and hydraulic system are normally transported Row places safety barrier and caution board at the scene around operation, prevent roadside pedestrian from interfering operation, starts crane leg, will Crane fixes on the ground, and No. 2 transformers are placed on just follow-up work by No. 1 transformer with crane, and bypass power cable is put down Row is placed on felt pad without intersection, is attached according to corresponding phase color and No. 3 transformer high-low-voltage connectors, by bypass electric power electricity The ground terminal of cable is attached with No. 2 and No. 3 transformer cases, forms reliable ground networks, anyone is forbidden to cross over, step on Step on bypass power cable region;Check that the high-low pressure disconnect switch of No. 3 transformers is in open position, operator after inspection Member successively leaves from No. 3 transformers, and standard is each before carrying out operation, and tool needed for operation is checked and checked, circuit staff The insulator arrangements such as insulation safety cap, insulation clothing are dressed.
Sessions: operation responsible person contacts upper layer scheduling, confirms job content, it is desirable that if making between not powering off operational period There is singlephase earth fault in industry region, and scheduling should disconnect this section of regional power grid in time, and personnel confirm job content, operation The division of labor, item of taking care strengthen awareness of safety, and electrician enters insulation bucket arm car, and power tool is categorized into bucket and neutralizes work Have in bag, fasten seat belts, rise aerial lift device with insulated arm, close to No. 1 transformer, check No. 1 transformer lead interface, to there is safety The connecting part of hidden danger carries out insulation processing, should have at the no less than mask overlap of 15cm at every section of insulating seam, according to No. 1 transformation Bypass power cable connect with No. 1 transformer, and will shunt cable and high-voltage switch gear and low tension switch holding foot by device phase color Enough distances.Judge whether bypass cable normally circulates with shift ammeter, checks whether the indicator light of No. 3 transformers is normal, work After making responsible person's confirmation, high-voltage switch gear is closed, after the total road nuclear phase of low pressure for detecting No. 3 transformers is normal, closes low tension switch, No. 1 transformer and No. 3 transformers is set to be in paired running state;
The cable current intelligence that connection No. 1 transformer and No. 3 transformers is observed with the button type ammeter moment, when No. 1 transformation When device cable current value reduces, the current value of No. 3 transformers is increased, and to ensure bypath system normal operation, first pulls down No. 1 later The low voltage knife switch of transformer, high voltage drop-out type fuse cutout under post-tensioning, electrician personnel climb up No. 1 transformer, remove drawing for transformer No. 1 transformer is changed in wire terminal, and No. 2 transformers rise to the origin-location of No. 1 transformer;The position of No. 2 transformers is fixed, According to the separate of No. 3 transformers, the pigtail splice on No. 2 transformer both sides is connected correct, staff returns to ground, closes 2 The high voltage drop-out type fuse cutout of number transformer carries out nuclear phase after confirmation phase sequence is correct to No. 2 transformers with multimeter and closes No. 2 Between the low pressure knife of transformer, the high-low voltage leads on No. 2 transformers are detected with clamp ammeter, at this point, current value and No. 1 transformation The current value of device is almost the same, guarantees that No. 2 transformers and No. 3 transformers are run parallel;
According to first low pressure, the operation order of rear high pressure first pulls open the low tension switch of No. 3 transformers, then pulls open high-voltage switch gear, So that 3 transformers is exited power distribution network, former route lap-joint is restored to insulate, bypass power cable is carried out at electric discharge with ground line Reason starts to remove bypass power cable, removes bypath system and sets respectively, site clearing, notice scheduling, and livewire work work is completed.
Ending phase: operation correlation direction board is removed in site clearing, arranges managing security tools and instruments;Check Work tool and material Nothing is left;The rubbish left when prune job;
Work termination, confirms that all insulation shieldings are not left, staff, which checks the number of people, leaves job location;Handle work Make ticket termination formality.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies Within, then the present invention is also intended to include these modifications and variations.
