10kV is charged to be connect broken string operation and belongs to simple live line working project, conventionally completed by a people, but find in long term operation, in operation process, there are the following problems in the past: 1) operating personnel goes between and holds one, wire with one of wire when overlap joint and hold lead-in wire, while overlap joint, lead-in wire is unreliable fixing with wire, if insulating gloves is damaged in operation process, easily cause the person to seal in circuit in lead-in wire overlaps journey, cause electric shock, there is very big operating risk in the method, also ubiquity is habitual violating the regulations simultaneously; 2) when operating personnel goes between with wire overlap joint, need first control lead-in wire fixture anchor leg, then go between and wire overlap joint; Large in this operation process operating personnel operation easier, labour intensity is high;
The developing direction of live line working is now the architecture advances by Work tool, makes live line working process reduce labour intensity, avoids operating risk, stops habituation and operates against regulations.
Summary of the invention
The utility model provides a kind of lead wire insulation fixture, is the charged special purpose device that connects broken string of 10kV, can make live line working process reduce labour intensity, avoids operating risk, stops habituation and operates against regulations.
In order to achieve the above object, the utility model is realized by the following technical solutions:
Lead wire insulation fixture, is made up of caliper, insulated handle and bearing pin, and the caliper of integral type and insulated handle are fixed together by bearing pin symmetry, forms pincerlike structure, offers wire holddown groove and lead-in wire holddown groove on caliper.
Described caliper one side is established lead-in wire holddown groove, and opposite side correspondence position is established wire fixture, and wire fixture is made up of fixed block and bolt, is connected with caliper by bolt, and fixed block is provided with the groove corresponding with the holddown groove that goes between.
Described insulated handle place is provided with back-moving spring.
Described insulated handle place is provided with bolt.
The material of described caliper is aluminium alloy.
Compared with prior art, the beneficial effects of the utility model are:
1) the utility model is that distribution line connects broken string special purpose device, can improve live line working method, reduces labour intensity, avoids operating risk, stops habituation and operates against regulations;
2) in actual applications, the charged broken string job safety rate of failure that connects of annual nearly 700 10kV is 0, safe;
3) easy to operate, improve operating efficiency, be applicable to insulating gloves working system and insulating bar working system, reduce instrument use amount, improve power supply reliability.

Fig. 1 is structural representation of the present utility model.
In figure: 1. caliper 2. insulated handle 3. bearing pin 4. wire holddown grooves 5. holddown groove 6. bolt 7. fixed block 8. back-moving spring 9. bolts that go between
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Seeing Fig. 1, is the structural representation of lead wire insulation fixture described in the utility model.
The charged special purpose device going between on fuse switch that connects of the utility model 10kV, the utility model lead wire insulation fixture, formed by caliper 1, insulated handle 2 and bearing pin 3, the caliper 1 of integral type and insulated handle 2 are fixed together by bearing pin 3 symmetries, form pincerlike structure, on caliper 1, offer wire holddown groove 4 and lead-in wire holddown groove 5.
Caliper one side is established lead-in wire holddown groove 5, and opposite side correspondence position is established wire fixture, and wire fixture is made up of fixed block 7 and bolt 6, is connected with caliper 1 by bolt 6, and fixed block 7 is provided with and groove corresponding to holddown groove 5 that go between.
Described insulated handle 2 places are provided with back-moving spring 8.
Described insulated handle 2 places are provided with bolt 9.
The material of described caliper 1 is aluminium alloy.
Wire holddown groove 4 on the utility model lead wire insulation fixture and lead-in wire holddown groove 5 are respectively used to fixing cord and lead-in wire, wherein go between fixing by the bolt 6 on wire fixture and fixed block 7, wire is clamped in the wire holddown groove 4 at jaw place, in the time that diameter of wire exceedes jaw diameter, by being tightened to rear realization, fixes by the bolt 9 at insulated handle 2 places.When use, first screw wire fixture and will go between fixingly, then by the insulated handle 2 of holding with a firm grip, jaw is opened, release handle after clamping wire.
Lead wire insulation fixture has easy for installation, fixes the features such as reliable, has avoided the potential safety hazard in many hot line maintenances, has significantly reduced operating personnel's labour intensity.
Go between operation as example taking charged the connecing on fuse switch of 10kV below, illustrate and adopt the utility model to complete lead-in wire and fixing concrete grammar and the operating procedure of main traverse line:
1) in bucket, electrician operates aerial lift device with insulated arm, enters live line working region;
2) the interior electrician of bucket adjusts to insulate and struggles against to the mutually suitable service position of inner edge of fuse switch, according to the order of " from the close-by examples to those far off ", " from top to bottom ", " first big after small ", to the position that may touch in the operation masked isolation that insulate, the position of covering and order are followed successively by the earth electrode that fuse switch lead-in wire, fuse switch, wire and setting close on; Three-phase conducting wire and fuse switch arrange the order of the measure of covering of insulating should carry out according to middle entry after selecting both sides mutually;
3) the interior electrician of bucket adjusts to insulate and struggles against to proper operation position, wire place, and measure is covered in the insulation of taking apart on wire, after strip off wire external insulation layer, recovers insulation and covers measure;
