Description
Technical field
The present invention relates to the special protecting wire net of a kind of Junk prevention, particularly a kind of special protecting wire net being applicable to all 35kV to 220kV main transformer 10kV sides internal overhaul Junk prevention.
Background technology
In recent years, along with the development of electrical network, the service work of various main transformer is increasing.When 10kV side sleeve pipe and inner lead dismounting are carried out in main transformer maintenance, owing to raising the restriction of seat hand hole door size and site examining and repairing position by 10kV side, in operation process, very easily the small articles such as generating tool, bolt falls into the accident of main transformer inside accidentally.And the metal objects such as instrument, bolt falling into main transformer inside is as taken out not in time, after main transformer runs, very easily causes the faults such as main transformer internal short-circuit, electric discharge, cause substantial equipment accident.
Owing to there is no complete 10kV side internal overhaul Junk prevention measure, whenever main transformer maintenance enter into this link all allow maintainer spirit high-pressure, pressure multiplier.Have small articles to fall into main transformer inside, all need to drain the oil to main transformer and send someone to pierce main transformer inside and find, sometimes even need main transformer again to hang cover, a little error in work has often developed into a major issue at every turn.Not only consume a large amount of manpower and materials, the maintenance duration that also occasions a delay, the adverse consequences that can not on time to put into operation etc.
This problem of easy junk during in order to solve the inner lead dismounting of 10kV side, maintainer takes colligation cord on handle for tool to prevent instrument from dropping, the method that interim paving layer of plastic film prevents bolt from dropping in the hand hole door of 10kV side.But because 10kV side hand hole door inner surface is very smooth, the interim plastic film laid does not have suitable position to be fixed, as long as exert oneself a little when pull 10kV goes between, plastic film will landing or positioning.This method of junk that prevents produces little effect, and the small articles such as small tool, bolt, nut accidentally fall into main transformer internal phenomena and still happen occasionally.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and provide a kind of easy to install, the tight special protecting wire net of main transformer 10kV side internal overhaul Junk prevention reliably can be protected.
The special protecting wire net of a kind of main transformer 10kV side internal overhaul Junk prevention, include a protecting wire net major network, described protecting wire net major network is half umbrella-shaped structure, it includes the umbrella frame stay of arc, major network cloth, tensioning stay, fixed mount and wire side tensioning frame, one end of the umbrella frame stay of described arc is hinged on fixed mount, one end of tensioning stay is connected on umbrella frame stay, the other end of tensioning stay is articulated with on wire side tensioning frame, the bottom of described wire side tensioning frame is cone structure, the upper end of described fixed mount is provided with the concave architecture matched with the cone structure of wire side tensioning frame bottom, the bottom of fixed mount is the structure of flute profile, the lower horizontal edge of flute profile is provided with a screwed hole, bolt is provided with in screwed hole, bolt can move in opposite thread hole, bolt head is connected with one for the handle of rotating bolt, described major network cloth is arranged on umbrella frame stay, major network cloth is provided with T-shaped hole, the horizontal edge in T-shaped hole is positioned at the medium position of protecting wire net major network, and horizontal edge extends along the dual-side of protecting wire net, the straight flange in T-shaped hole extends to the edge of protecting wire net major network cloth, T-shaped hole is provided with two panels and is oppositely arranged adhering buckle, the elastic adhesive button that two panels is oppositely arranged each other male and female can be mutually bonding.
During use, protecting wire net in folded state is raised seat hand hole door from main transformer 10kV side and put in rising seat inside, 10kV side, again the elastoplast adhering buckle wire side is torn from inverse-T-shaped tapping by protecting wire net, pitch need to carry out work 10kV side lead or pigtail splice below.With elastoplast adhering buckle, lead or lead-in wire are encased, then clutch the gap that elastoplast adhering buckle closes lead or lead-in wire surrounding.The part of fixed mount flute profile is stuck in 10kV side and raises seat hand hole door edge, turning handle makes bolt hold out against hand hole door steel plate, is reliably fixed on hand hole door outer wall by major network fixed mount.Next wire side tensioning frame is pinned, by in the groove of the conoid end of wire side tensioning frame press-in major network fixed mount upper end, utilize the acting in conjunction of tensioning stay and umbrella frame stay that whole protecting wire net major network is opened completely, thus protecting wire net is installed, the internal overhaul work of 10kV side can be carried out.
The both sides being positioned at that one end of fixed mount at major network cloth arrange bivalve side screen cloth, and side screen cloth is connected on major network sheet, the joint of two panels side screen cloth is provided with adhering buckle and is connected by two panels side net.
Be drawn out to hand hole door by two panels side net in major network in use, the adhering buckle between the net of closed two panels side makes it join together, thus carries out omnibearing protection to main transformer.
Described adhering buckle is elastoplast adhering buckle.
The wire side of described protecting wire net major network, side net all adopts glass fiber mesh that is corrosion-resistant, oil resistant.
Described umbrella frame stay and tensioning stay are made by thin circle stainless steel strip.
Described handle and bolt are integral type structure.
Described wire side tensioning frame, holding pin handle and holding pin are engineering duroplasts material.
In sum, the present invention's following advantage compared to existing technology:
The special protecting wire net of main transformer 10kV side internal overhaul Junk prevention of the present invention, adopts major network and side net fit system, makes integral protection more tight, reliable; External fixed mount coordinates with wire side tensioning frame can provide enough fixing and support to protecting wire net, and installation process can not cause any damage to main transformer internal unit; Inverse-T-shaped perforate on protecting wire net is applicable to 10kV lead or the lead-in wire of various shape thickness; Adopt elastoplast adhering buckle can quick closure lead or lead-in wire surrounding gap, and lead or lead-in wire twitch time not easily get loose; Exclusive recessed wire side does not take 10kV side at work and raises the inner limited working space of seat, does not affect the normal running of maintainer.Half umbrella design adopted is convenient to protecting wire net and is launched and fold, and makes the mounting or dismounting of protecting wire net and turnover 10kV side raise seat hand hole door all very convenient.Protecting wire net material is all based on glass fibre or plastic material, and all metallic portion are all above wire side or outside hand hole door, adopts riveted joint or welding manner to connect, and avoids the drop situation of main transformer inside of protecting wire net metal parts and occurs.This protecting wire net very applicable 35kV to 220kV main transformer 10kV side internal overhaul uses.
