Description
Technical field
The present invention relates to electrified track traffic tractive power supply system series insulation equipment, a kind of electromechanical properties excellence of main invention can realize the insulation equipment of online quality-monitoring, is specially intelligent porcelain composite insulator series of products for electrified track traffic tractive power supply system.
Background technology
Country's Mid-term and Long-term Plan of the Railway Network proposes the year two thousand twenty, and china railway revenue kilometres reach 100,000 kilometers, and complex line rate and electrochemical rate all reach 50%, and major technique equipment reaches or approaches advanced international standards.Urbanization Construction is carried forward vigorously in the national economic and social development planning, and urban population sharply increases, and traffic is seriously obstructed, and therefore urban rail transit in China construction development rapidly.The construction of electrified track traffic must be used insulation equipment in a large number, porcelain, glass and the composite insulator that at present scale is used made huge contribution for China's economic development, but along with the construction object of 21st century intelligent grid, electrified track traffic tractive power supply system also must stride forward to the target of reliable, safety, economy, efficient, environmental friendliness and use safety.But current used insulator can not be realized real time monitoring function, has potential safety hazard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of this invention is to provide a kind of rational in infrastructure, can carry out online quality-monitoring, security performance is high, stability is high electrified track traffic tractive power supply system Intelligent insulating.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of electrified track traffic tractive power supply system Intelligent insulating, comprise insulator body, an end in insulator body is provided with lower annex, on the inwall of described lower annex, be provided with pressure sensor, between the full skirt of insulator body and described lower annex, be provided with oversheath, described leakage current collecting ring is set on described oversheath,, on described leakage current collecting ring and pressure sensor, be all connected with lead-in wire.
Beneficial effect: compared with prior art, the invention has the advantages that, at the inner implantable pressure transducer of lower annex, embed leakage current collecting ring at surface of outer sheath, and coordinate corresponding acousto-optic prior-warning device, can real time on-line monitoring insulator body mechanical performance and the running quality of electric property, and judgement and send visualization quality pre-alert.This invention can realize insulation equipment on-line real time monitoring efficiently and effectively, thereby reaches the intellectuality of insulator body.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 be in Fig. 1 B-B to cutaway view.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, a kind of electrified track traffic tractive power supply system Intelligent insulating, comprise insulator body 1, lower annex 2, pressure sensor 3, oversheath 4, leakage current collecting ring 5, lower annex 2 is located at an end of insulator body 1, and described pressure sensor 3 is embedded on the inwall of described lower annex 2.The quantity of pressure sensor 3 has 4 and be distributed on described lower annex 2.Between described lower annex 2 and insulator body 1, be provided with glue layer 6.
Oversheath 4 is located between the full skirt of insulator body 1 and described lower annex 2 and is coated in insulator body 1, described leakage current collecting ring 5 is set on described oversheath 4, is all connected with lead-in wire 7 on described leakage current collecting ring 5 and each pressure sensor 3.Leakage current collecting ring 5 is by the external acousto-optic prior-warning device 8 of connected lead-in wire 7; Each pressure sensor 3 is all by the external acousto-optic prior-warning device 8 of connected lead-in wire 7.
In order to be more firmly located on sheath, described leakage current collecting ring 5 is embedded in the interior 2mm ± 0.5mm of oversheath 4.The material of described leakage current collecting ring 5 is aluminium matter.Described oversheath 4 is silicone rubber jacket.
Pressure sensor 3 shapes are small and exquisite, stable performance, induction are sensitive, and be embedded in lower annex 2 inwalls, lead-in wire 7 is drawn from leakage current collecting ring 5 belows, be connected in the acousto-optic prior-warning device 8 that is fixed on electrified track traffic or mechanical column or roof or power station column or steel tower cross-arm.Pressure sensor 3 can the operating mechanical load of real-time collecting product and is passed to acousto-optic prior-warning device 8, and the built-in automatic analysis system of acousto-optic prior-warning device 8 carries out computational analysis and judgement by the parameter of modulation in advance.If product mechanical performance in service is normal, acousto-optic prior-warning device 8 attonitys, if mechanical performance occurs extremely after product long-time running, acousto-optic prior-warning device 8 starts action and sound and light and reminds track walker that this product mechanical performance is abnormal simultaneously.
Leakage current collecting ring 5 is arranged on insulator body 1 low-pressure end (having one end of lower annex 2) near sheath position, multi-sealed district, end.This ring can embed securely jacket surface and embed 2mm left and right in sheath, this ring design lead-in wire 7 is connected with another acousto-optic prior-warning device 8, and this acousto-optic prior-warning device 8 is also fixed on electrified track traffic or mechanical column or roof or power station column or steel tower cross-arm.This acousto-optic prior-warning device 8 can Real-Time Monitoring insulator body 1 surface because of leakage current size filthy and moisture initiation, the leakage current on insulator body 1 surface 7 is poured in this acousto-optic prior-warning device 8 by going between through leakage current collecting ring 5, this acousto-optic prior-warning device 8 carries out computational analysis and judgement by the parameter of modulation in advance, and real-time analysis goes out the filthy state on insulator body 1 surface and may occur pollution flashover accident., before insulator body 1 pollution flashover generation prerequisite, sound and light early warning through these acousto-optic prior-warning device 8 computational analysis at the leakage current of the online real-time collecting of its system, remind this product electric property situation of track walker.
In sum, adopt the present invention, can realize online quality-monitoring and visualization quality report, the quality accident that the electrified tractive power supply system that gives warning in advance brings because of insulation equipment, accomplish the intellectuality of electrified track traffic tractive power supply system with insulation equipment, guarantee the safety and stability of electrified track traffic tractive power supply system.
Certainly, acousto-optic prior-warning device 8 also can adopt two, is used for respectively Bonding pressure transducer 3 and leakage current collecting ring 5.
The above is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
