Summary of the invention
The object of the present invention is to provide a kind of operational method of 110kV circuit hotline maintenance suspension clamp, realize the practical approach of hotline maintenance suspension clamp.
The inventive method realizes through following steps:
The first step, clear and definite site safety monitoring personnel 1 people, first operation electrician 1 people, second operation electrician 1 people, ground cooperate personnel 2 people, clear and definite operation procedure and method, clear and definite safe distance and points for attention;
In second step, first and second electrician climbs shaft tower in succession, chooses job position, first electrician above the lead cross-arm, second electrician on shaft tower with the wire clamp horizontal level, obtain safety custody people permission after, can begin operation;
In the 3rd step, first electrician installs insulation with the second electrician upright position and transmits rope on cross-arm, and fixing behind length to the ground of adjustment rope;
In the 4th step, cooperate personnel upwards to transmit the insulating tool that operation is used with insulation ropes by ground;
In the 5th step, the insulating block group or the two cover insulation pull-rod type lifting gears of two cover tape insulations ropes are installed in both sides vertical with suspension clamp on cross-arm, and the lower end hook of two insulating block groups is used for hooking in opposite directions lead;
In the 6th step, the cooperation personnel tighten up lifting gear by ground, and wire clamp and insulator are broken away from;
In the 7th step, the second electrician operating personnel drags suspension clamp with the insulating bar hook, and the operating personnel on the cross-arm pushes suspension clamp with insulating bar, makes 90 ° of suspension clamp upsets, and the side of wire clamp hull upwards;
In the 8th step, after second operating personnel installs plain cushion, pin with insulating bar, and the opening pin is separated into 60-90 °;
In the 9th step, the recovery lead is connected with the insulator suspension and installs spring catch, removes insulating tool, shaft tower under operating personnel's safety on the shaft tower.
Adopt method of the present invention, can realize the hotline maintenance suspension clamp, safe.Can reduce power failure, improve the reliability of power supply.

Embodiment
Below the inventive method is done further explain, this method mainly is divided into eight steps:
The first step, clear and definite site safety monitoring personnel 1 people, first operation electrician 1 people, second operation electrician 1 people, ground cooperate personnel 2 people, clear and definite operation procedure and method, clear and definite safe distance and points for attention;
In second step, first and second electrician climbs shaft tower in succession, chooses job position, first electrician above the lead cross-arm, second electrician on shaft tower with the wire clamp horizontal level, obtain safety custody people permission after, can begin operation;
In the 3rd step, first electrician installs insulation with the second electrician upright position and transmits rope on cross-arm, and fixing behind length to the ground of adjustment rope;
In the 4th step, cooperate personnel upwards to transmit the insulating tool that operation is used with insulation ropes by ground;
In the 5th step, the insulating block group or the two cover insulation pull-rod type lifting gears of two cover tape insulations ropes are installed in both sides vertical with suspension clamp on cross-arm, and the lower end hook of two insulating block groups is used for hooking in opposite directions lead;
In the 6th step, the cooperation personnel tighten up lifting gear by ground, and wire clamp and insulator are broken away from; During operation, second electrician utilizes insulating bar to take off the spring pin at suspension clamp place bowl head and composite insulator place, and the ground electrician suitably tightens up the insulation tackle pulley; Or first the electrician on cross-arm, tighten up pull-rod type lifting gear, lead is promoted about 300mm, after second electrician utilizes insulating bar to make bowl head and composite insulator disengaging; The ground electrician loosens about the about 200mm of insulation tackle pulley; The bulb of bowl head and composite insulator is separated from fully, and will the insulate tail rope of tackle pulley of ground electrician fixes, or first electrician locks pull-rod type hoisting hook; See that Fig. 1 insulating block group lower end hook hooks lead in opposite directions and insulator breaks away from sketch map;
In the 7th step, the second electrician operating personnel drags suspension clamp with the insulating bar hook, and the operating personnel on the cross-arm pushes suspension clamp with insulating bar, makes 90 ° of suspension clamp upsets, and the side of wire clamp hull upwards;
In the 8th step, after second operating personnel installs plain cushion, pin with insulating bar, and the opening pin is separated into 60-90 °;
During operation, second electrician uses insulating bar to catch on suspension clamp, rotates suspension clamp, makes suspension clamp outside gyroaxis closed pin installing hole high-visible.Use action bars that plain cushion and closed pin are installed then;
In the 9th step, the recovery lead is connected with the insulator suspension and installs spring catch, removes insulating tool, shaft tower under operating personnel's safety on the shaft tower.
Implement this method, on-the-spot in live line working, the requirement of safety operation and points for attention, strictness is carried out by relevant electric power safety regulations and live line working rules, in the method, does not elaborate.
