Abstract
The utility model discloses a power clamping apparatus. The utility model is suitable for the live line work on the replacement of deteriorated isolators for the power transmission lines of 220KV to 500KV. The utility model is characterized in that both sides of an upper clamping-plate clamping apparatus and a lower clamping-plate clamping apparatus are respectively provided with a direct current electric motor and a speed reduction driving mechanism which is connected with an output shaft of an electric motor, and are also provided with a control box which provides a power supply and controls the electric motor to move; the upper clamping apparatus and the lower clamping apparatus are connected by a screw rod nut pair. The utility model only needs the matching operation of three people, and completes the live line work on the replacement of the hanging string isolators of the power transmission lines. The work process is simple, the work efficiency is high, and the whole apparatus is simple and light.
Description
Technical field
The utility model relates to a kind of extra high voltage network live line working erecting tools, and particularly a kind of self possess power and can replace human body to enter the power jig device of equipotential live line working.
Background technology
So far, the insulator of changing 500 kilovolts of extra high voltage networks is to adopt the load jig that manually tightens up and loosen, and when carrying out live line working, the operating personnel must enter the equipotential operation.Since be subjected to safe distance constraint, many positions do not allow the operating personnel to enter equipotential, thereby limited the scope of application of using jig charged for replacement insulator, as in the electric transmission line isolator string, accounting for the string that dangles of the overwhelming majority, all can not change operation with jig.The existence of live line working forbidden zone is unfavorable for improving the availability factor of transmission line and safety, the stable operation level of big electrical network.And the patent No. be 94247710 general rear end jig is not complete kit, and it just unloads a part in the kit of bunch of insulator behaviour working system.The instrument that this operating type uses also comprises than the long insulation arm-tie of insulator string and bottle supporting frame, insulating bar, front end jig, the kit complexity needs 5 people's carryings, transportation and used with journey in, the also essential good insulation performance state that keeps of insulation arm-tie and bottle supporting frame, the scope of application is little.
Summary of the invention
The purpose of this utility model is that power is set on jig, by the rope or the action bars of insulation, with the tightening up and loosen of control jig, makes when changing the deterioration insulator, avoids operating personnel's equipotential operation jig, realizes charged safety operation.
The utility model is realized in such a way: the insulator of being made by clamping plate is jig (being similar to the front and back end jig) up and down, DC motor, reduction gearing mechanism, DC power supply, the hot line maintenance power jig device that control cabinet and feed screw nut pair etc. are formed, when the deterioration insulator on the transmission line is changed, at first the sufficient electric weight of the DC power supply in the power jig device, turn on the power switch then, whole power jig device is passed on the electric tower with the insulation rope, by staff on the electric tower power jig device is hung near the insulator position that needs are changed, the insulator that aligning will be changed (Fig. 2), and by the jig up and down that the staff will open with action bars be enclosed within need to change insulator on, on the steel cap of following insulator.Operating personnel's tractive insulation control rope on the electricity tower, open the lifting switch, DC motor starts immediately, screw mandrel is tightened up, jig is up moved, after insulator rises to desired location down, the lead limit switch action, motor is stopped transport, and the insulator that will change this moment is in relaxation state, and the operating personnel finishes more changing jobs of deterioration insulator with the dedicated operations bar on the tower.After having changed insulator, the staff's tractive insulation control rope on the electric tower is opened reversion switch, makes the motor start-up counter-rotating, and screw pair loosens, and the power jig is returned back to initial condition.Open jig up and down with action bars, unclamp jig, make it all break away from insulator string, power jig device is hung on cross-arm regain.The utility model only needs three people's compounding practices on the shaft tower, operation process is simple, high efficiency, thoroughly broken through the forbidden zone of jig method live line working, simplified loaded down with trivial details live line working method comprehensively, and applied widely, and insulator is changed in the live line working that can be used for extra high voltage networks such as 220KV, 330KV, 500KV, electric pressure is high more, and it is simple, light, advantage obtains performance more efficiently.
Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail:
