Description
Technical field
The invention belongs to technical field of electrical equipment, particularly, relate to a kind of half fixed sealing type cable termination plug-in and pull-out device.
Background technology
Each phase core of high-tension cable all has (copper) screen of a ground connection outward, conductive cable core forms radially-arranged electric field therewith between screen, namely the electric field of normal cable is only from core conductor along the power line of half radial screen, do not have the electric field (power line) of core tangential (axis), Electric Field Distribution is uniform.During usual making cable termination, need to divest outer shielding layer, this just changes the original Electric Field Distribution of cable, the tangential electric field totally unfavorable to insulation will be grown, concentrate to screen incision position at the power line divesting screen heart yearn, cause this incision position very easily to cause cable insulation to puncture, so will adopt, dielectric constant is 20-30, specific insulation 108-1012 Ω .cm material makes electric stress control valve (abbreviation stress cone) and is enclosed within screen incision position, to disperse the electric field stress (power line) of incision position, ensure cable energy reliability service.
In recent years along with the development of electrical network, have and increase year by year compared with the equipment such as combined electrical apparatus, ring main unit, switching station of small footprint size, outlet cable supporting is with it also corresponding to be multiplied, all adopt preset inner cavity chamber to plug fixing form between equipment and cable to be electrically connected, namely cable termination form is half fixed sealing type.At present, half fixed sealing type cable termination plug all adopts stretched wire lever to insert and manpower pulls two kinds of modes and carries out: 1) adopt easy stretched wire leverage tool to carry out update, during operation, the suspended end of stretched wire is fixed on gas-filling cabinet reserve in screw carry out suspension fix, then utilize lever one end to embed the other one end of connect-disconnect plug base to exert pressure, connect-disconnect plug is pushed in preset inner cavity chamber the bolt that is tightened and can complete update; 2) adopt manpower all around when removing bolt of lower base to rock cable plug head local repeatedly to pull finally to complete and pull away operation.These two kinds of operation formats particularly the latter cannot reach in order, link up, steadily and uniform force in whole operating process, thus very easily cause the phenomenons such as the change of stress cone surface damage, local size, mechanical stress concentration, and this damage cannot be monitored, under long-term accumulated, affect its internal electric field stress cone local field strength distribution dispersion usefulness to reduce, initiation tree discharge or partial discharge cause accelerated ageing or Frequent Troubles.
