Description
Technical field
What the present invention relates to is a kind of generator stator bar and the combination removal tool of headgear and method for dismounting, belongs to generator unit stator service technique field.
Background technology
The stator bar of generator is evenly distributed on inside the silicon steel sheet of generator unit stator, is embedded in the slot wedge that superposed by multilayer silicon steel sheet; Stator headgear comprise and headgear and lower and headgear, and be made up of copper metal material respectively, top layer boring tin be silver gray, and their effect to be entangled up and down by stator bar joint and together soldered, thus line rod is concatenated the coil of formation conducting.
No matter the stator maintenance of generator is change stator bar, or processes the problems such as line rod joint poor flow, all must first the also head part of line rod be removed.And head part comprises the metal of outermost epoxy insulation box and internal layer and headgear.Remove the metal of internal layer by conventional method and headgear time, first with heating tool, high-temperature heating is carried out to it, make the soldering adhesion partial melting between it and line rod, and then with hammer add flat chisel carry out shoveling hit and the mode of the artificial withdrawing of auxiliary locking pliers will and headgear remove.
There is two problems in this traditional method for dismounting:
(1) operate dangerous: remove by traditional method, high temperature and the melting welding slag of headgear and splashing very easily causes human body to scald; Simultaneously because line rod joint belongs to red copper metal material, soft pliable at high operating temperatures, and this method for dismounting can make and headgear unbalance stress, can cause the impaired distortion of line rod joint.
(2) operating efficiency is low: this work needs two people to coordinate to carry out, and closely manual work under the headgear condition of high temperature, personnel are nervous.And and headgear bite position is uncertain, be difficult to firmly, construction schedule is slow, even there will be and extracts because impacting in time and cause repetition scorification, more take time and effort.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, use easy to operate, can effectively prevent the person from scalding and the impaired distortion of line rod, significantly shorten maintenance duration, significantly improve and headgear dismounting operating efficiency simultaneously, effectively discharge the generator stator bar of labour and the combination removal tool of headgear and method for dismounting.
The object of the invention is that following technical scheme come, a kind of generator stator bar the combination removal tool of headgear, described line rod headgear comprise also headgear and lower and headgear, described combination removal tool comprises and is respectively used to remove the upper of upper and headgear and lower and headgear and headgear remover and lower and headgear remover, wherein:
