Description
Technical field
The present invention relates to combined electrical apparatus detection equipment technical field, be specifically related to a kind of comprehensive examination and repair system of combined electrical apparatus based on storehouse, movable type side.
Background technology
Combined electrical apparatus is divided into open type and totally enclosed type two kinds by insulation system.The former withCombined electrical apparatusOr breaker is main body, willCurrent transformer、Voltage transformer, cable first-class element common combination therewith forms.The latter is to be sealed in grounded metal enclosure at the electrification in high voltage position of each element, is filled with the good gas of insulating properties, oil or solid dielectric insulation in shell, each element (generally comprise breaker, combined electrical apparatus,Earthed switch, voltage transformer, current transformer,Bus、Arrester, cable termination etc.) by wiring requirement, be sequentially connected with and form a whole.Sulfur hexafluoride (SF6) the totally-enclosed electrical equipment that the sixties in 20th century occurs has the features such as installation volume is little, security performance good, reliability is high, time between overhauls(TBO) length, therefore quickly grows.
Fully closed combined electric unit i.e. GIS is that the sulfur hexafluoride gas i.e. SF6 gas utilizing and having superior insulation performance is as insulation and arc-extinguishing medium, each electrical equipment is sequentially connected with and forms a whole, a kind of novel high-pressure electrical equipment in being entirely encapsulated in sealed up metallic ground housing, has the distinguishing features such as miniaturization, component module, reliability high, arc extinguishing ability is strong, cooling characteristics good, installation period is short, length in service life.But along with running the increase of the time limit, equipment engenders SF6 gas leakage problem, causes gas pressure to decline even latch switch action, makes air chamber water content increase, and harm is insulated, affected arc extinguishing, also can produce noxious material, threatens health of human body.Properly functioning for ensureing equipment, have to before leak detection, leak stopping supplement SF6 gas, increase maintenance cost.Currently, the leakiness position of multiplex highly sensitive probe detection equipment of hunting leak, leak stopping mostly then is and tightens fastening bolt, changes the Pressure gauge of gas leakage, seal, porcelain bushing shell etc., the requirement can not meet site examining and repairing far away, stopping a leak.
The leak detection of a kind of fully closed combined electric unit scene of the disclosure of the invention of Application No. 201310623730.2, leak-stopping technique method belong to technical field of electric power.The technical scheme is that the on-the-spot SF6 gas difference leakage position to fully closed combined electric unit emerged in operation, use integrated supervision, pressure to decline the method such as analysis, segmentation location, local accumulation, soap bubble method, fluid sealant method flexibly and accurately detect leakage point, and then implement strict technology targetedly, repair welding weld seam, sample block up in a state of excitement, install the leak stopping such as pressure cap, renewal part additional processes process, rapid restorer runs.Providing the benefit that: simple and easy to do, leak detection the most rapidly, reduces blindness, and leak stopping is simply effective, reduces workload, and the cost of overhaul is low, and maintenance efficiency is high, greatly reduces equipment and stops transport, and ensures equipment safety operation, society and remarkable in economical benefits.This invention provides a good environment can not to maintenance, and cannot arrange fixing for small part during maintenance, and scene is the most mixed and disorderly.
The invention of Application No. 201220713696.9 provides a kind of gas insulated combined electric appliance equipment service kit, and including base, guide rail, crossbeam and derricking gear, described guide rail is connected by rail brackets and base are fixing；Described crossbeam is connected by crossbeam pillar and base are fixing；Described derricking gear is flexibly connected with crossbeam by the hook of himself, and derricking gear is provided with guide chain；The quantity of described guide rail is two, and is connected by bolt and rail brackets are fixing respectively；Weld between described rail brackets and base.The beneficial effects of the utility model are as follows: by by gas insulated combined electric appliance equipment service kit, carry out the dismounting of breaker mechanism and more change jobs, avoid staff's hand half the circumference of the sleeve where it joins the shoulder to shoulder, alleviate the labour intensity of about 40%, make the replacing construction of separate unit breaker by original 5-6 hour, it is reduced to 3 hours, improves operating efficiency.But this invention remains adaptation environment, and cannot create environment, so under the extreme cases such as rainy weather cannot site examining and repairing, needing that high-voltage switch gear moves to other places could overhaul, use limitation bigger.
And, current prior art is when combined electrical apparatus Disintegration overhaul, and the longer member such as the parts especially conductive arm of the combined electrical apparatus that dismounting is lower the most reasonably puts place, is often placed in ground, cleans the most convenient, inefficiency when polishing.Additionally, the widgets such as screw, nut and pad are usually lost, are damaged.Combined electrical apparatus Disintegration overhaul works, and is a kind of electric operating exigent to standard operation, and nonstandard putting easily causes working site confusion, creates potential safety hazard, also service work is caused strong influence.
