Description
Technical field
The present invention relates to a kind of power tool that is used for installation, maintenance, repairing or the dismounting of overhead transmission line, especially for the instrument of the charged for replacement circuit strain insulator in the 110KV circuit.
Background technology
Transmission line is in the process of operation, owing to receive the influence of various factors, the damage of insulator is inevitable, in order to guarantee power supply reliability, must in time change the insulator that damages.For 110 KVs, mostly iron tower is to return with bar is two, and the form of lead vertical arrangement is more; The minimum safe distance of regulation electrified body and earth electrode is 1.0 meters in the safety regulations; Satisfy safe distance under the situation, in order to save the space, the bulk of iron tower is very little.For 110 kilovolts of three-phase conducting wire vertical arrangement iron towers; Last phase and middle strain insulator mutually, charged for replacement is difficult to operation, and replacing generally has a power failure; But the power failure operation reduces the power supply reliability index greatly; And circuit is in the process of operation, when insulator defective occurs and can not have a power failure the time, defective can't in time be eliminated; For following phase strain insulator; The operating type that can take equipotential to combine with earth potential carries out charged for replacement; But adopt hanging basket or insulating ladder to get into electric field as the equipotential mode complicated operation, loaded down with trivial details, one of which, to guarantee that the operating personnel is in identical current potential with electrified body; Thereby assurance safety, but this mode exists shortcoming to have: 1) influenced by site environment bigger for hanging basket; 2) adopt the hard ladder of insulation, rope ladder to get into electric field, be difficult for satisfying minimum safe distance; 3) receiving tower structure formal constraint 4) activity duration is long, required personnel are many, and operation process is complicated, loaded down with trivial details.
Lots of field maintenance experience shows; Live line working for general elimination line defct; Take the earth potential working form, can reduce the average operation time and the operating personnel reaches 50%, but need to guarantee operating personnel and the certain safe distance of repair apparatus live part maintenance; Electric pressure is high more, and its requirement to repair apparatus is also just high more.Solve phase and the difficult problem of the middle charged for replacement of strain insulator mutually on 110 KVs; Reduce the activity duration of phase strain insulator under the charged for replacement, required manpower simultaneously; This just must develop and improve the power tool of changing strain insulator; Improve its convenient and reliable operation property as far as possible, and then take operating process comparatively simple, the less earth potential working mode of required personnel is changed insulator.
Summary of the invention
The present invention provides a kind of instrument of charged for replacement circuit strain insulator; It can be applicable to the earth potential working mode; Solve phase and the difficult problem of the middle charged for replacement of strain insulator mutually on the circuit, reduce the activity duration of phase strain insulator under the charged for replacement, required manpower simultaneously.
For realizing above-mentioned purpose, the technical scheme that the present invention takes is: a kind of instrument of charged for replacement circuit strain insulator comprises preceding card, back card, pressure pin and insulated tension pole; The quantity of pressure pin and insulated tension pole is all 2, card and back card before the two ends of each pressure pin and insulated tension pole removably connect respectively; Also be respectively equipped with the hole clipping that is used to block strain insulator two ends fixture in the middle part of the body of preceding card and back card.
