Description
Technical field:
The utility model relates to a kind of insulating support for fixing drainage thread, is widely used in overhead distribution on-load and changes in high voltage side of transformer lead-in wire, fixing bypass cable drainage thread work, belong to hotline maintenance site technology field.
Background technology:
At present when carrying out 10kV distribution on-load and changing high voltage side of transformer lead-in wire work, do not have special tool utensil to carry out insulation to insulation lead wire to fix, in operation process, drainage thread swings unstable, alternate and discharge accident is over the ground there is for preventing charged drainage thread, insulated target can only be used progressively to cover electrified body and earth electrode, in masking process, there is the danger of operating personnel's phase fault, single-phase earthing; After having covered, when carrying out distribution transformer live line working, exist cover not exclusively, not firm, the complicated danger that personal equipment breakdown easily occurs of construction.
For a change above-mentioned situation occurs, and is badly in need of a kind of insulating support for fixing drainage thread of development, finally realizes safety, completes the work of on-load replacing distribution transformer high-side lead fast.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of structure simple, safe and reliable, flexible adjustment, install firm, applied widely, improve live line working efficiency, guarantee the insulating support for fixing drainage thread of live-working safety.
The purpose of this utility model can be reached by following measure: a kind of insulating support for fixing drainage thread, it is characterized in that it comprises metal firm banking, the upper end of metal firm banking connects one end that two level insulation support tubing respectively, two level insulation support the protract upper end of tubing of the other end of tubing and insulation and are connected, two level insulation support between tubing V-shaped, the lower end of metal firm banking connects one end of two inclination insulating supporting tubing respectively, the protract lower end of tubing of the other end of two inclination insulating supporting tubing and insulation is connected, V-shaped between two inclination insulating supporting tubing, metal firm banking evenly connects two ratchet bracket fixtures, the protract front end of tubing of insulation evenly connects drainage thread holddown groove.
In order to realize the purpose of this utility model further, described ratchet bracket fixture is connected to form by ratchet band and band stay hook.
In order to realize the purpose of this utility model further, described described drainage thread holddown groove is 3.
In order to realize the purpose of this utility model further, the spacing of described adjacent two drainage thread holddown grooves is 0.6-0.8 rice.
In order to realize the purpose of this utility model further, the protract vertical range of tubing and metal firm banking of described insulation is 0.8-1.2 rice.
The utility model can produce following good effect compared with the prior art: the utility model by rigid insulation spacer assembly, solves and uses insulated target insulation to cover the little and inconvenient problem of operation of coefficient of safety.Drainage thread insulating support carries out insulating supporting to charged drainage thread, keeps enough safe distances with shaft, extends gas discharge path, improves discharge voltage value.The person, power grid security are protected, and eliminate the potential safety hazard in the work of on-load replacing high voltage side of transformer lead-in wire, ensure that the reliable and stable operation of equipment, improve power supply reliability after equipment application.
1, structure is simple, easy for installation.When using drainage thread insulating support, by ratchet bracket fixture, support is fixed on shaft; Insulated pipes used plays main insulation effect, keeps electrified body and the enough safe distance of earth electrode; The effect of drainage thread holddown groove is locked by lead-in wire, prevents artificial, wind-force effect from causing drainage thread to swing.
2, reliable, the technology maturation of equipment performance, perfect in shape and function, rational in infrastructure, meets the requirement of long charged steady operation.
3. coefficient of safety is high.Can the highly charged operating personnel of assisted Extraction coefficient of safety in the course of the work, effectively can reduce unnecessary insulation and cover, increase work efficiency, thus avoid people to be that misoperation causes unnecessary loss.
After using fuse switch insulating barrier, solve and use insulated target insulation to cover the little and inconvenient problem of operation of coefficient of safety, ensure that the reliable and stable operation of equipment, improve power supply reliability.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the end view of Fig. 1;
Embodiment:
Below in conjunction with accompanying drawing, execution mode of the present utility model is elaborated:
Embodiment: a kind of insulating support for fixing drainage thread (see Fig. 1-Fig. 3), it comprises metal firm banking 1, the upper end of metal firm banking 1 respectively bolt is fixedly connected with one end that two level insulation support tubing 2, two level insulation support the protract upper end of tubing 4 of the other end of tubing 2 and insulation and are connected, two level insulation support between tubing 2 V-shaped, the lower end of metal firm banking 1 respectively bolt is fixedly connected with one end of two inclination insulating supporting tubing 8, the protract lower end of tubing 4 of the other end of two inclination insulating supporting tubing 8 and insulation is connected, V-shaped between two inclination insulating supporting tubing 8, protract tubing 4 of insulation is 0.8-1.2 rice with the vertical range of metal firm banking 1.Metal firm banking 1 evenly connects two ratchet bracket fixtures 3, ratchet bracket fixture 3 is connected to form by ratchet band 6 and band stay hook 7, the protract front end of tubing 4 of insulation evenly connects 3 drainage thread holddown grooves 5, and the spacing of adjacent two drainage thread holddown grooves 5 is 0.6-0.8 rice.
