Abstract
The invention discloses a full-range discharge ring which comprises two semicircular discharge rings. Each semicircular discharge ring comprises a bearing bush, spokes, a circular discharge ring and discharge tips, the bearing bush is connected with the circular discharge ring by the spokes, and the discharge tips are arranged at the outer peripheral edge of the circular discharge ring. Aluminum alloy is integrally subjected to die casting to form each semicircular discharge ring. The full-range discharge ring has the advantages that the full-range discharge ring is excellent in mechanical performance and low in cost, is light, can be constructed conveniently and flexibly, and can be operated by workers after the workers are briefly trained, lightning critical flashover voltage is stable and reliable, discharge gaps can be flexibly adjusted as needed, and requirements of different service places are met.
Description
Technical field
The present invention relates to a kind of discharge ring, be specifically related to a kind of gamut discharge ring that is applied in the tension-resistant rod anti-thunder insulator.
Background technology
Along with the popularization of overhead distribution net insulating work, insulated conductor is prevented the research and comparison of lightning-caused breaking measure is many, but at present external insulative distributing line thunder protection measure is mainly used on linear rod insulator, to strain insulator without lightning protection measures.
Because the end of conventional strain insulator is a cast steel components, need a draw taper when actual production, therefore having caused the discharge ring that the location is installed inaccurate, fixing not firm.Cause that random variation appears in the contingency when two pairs of discharging gaps between the discharge ring are installed with the workmen, causes the unstable of discharge voltage.
Because cast steel components exists draw taper and surface roughness, the contacting mainly by installation dog screw and point few in number of discharge ring and cast steel components, through-current capability reduces greatly.When being subject to being struck by lightning, the power frequency short circuit current that continues is difficult to guarantee.
The discharge ring of prior art and conventional strain insulator are installed inconvenient, and when being subject to being struck by lightning, easily break, and circulation is poor, and the flashover voltage that provides is unreliable, and cost is higher.
Summary of the invention
The invention provides a kind of gamut discharge ring, with low cost, easy construction, flexible has stronger mechanical performance, can bear transfer and the dynamic thermal stability of thunder and lightning, large electric current, and reliable flashover voltage can be provided.
In order to achieve the above object, the present invention is achieved through the following technical solutions: gamut discharge ring, be characterized in, and comprise two semicircle discharge rings, each semicircle discharge ring comprises bearing shell, spoke, discharge annulus and discharge tip,
Above-mentioned bearing shell is connected by spoke between annulus with discharge;
Above-mentioned discharge annulus outer periphery is provided with discharge tip.
Above-mentioned bearing shell is Ω shape, and the outer arc surface of bearing shell is fixedly connected with an end of spoke.
The two ends bossing of above-mentioned bearing shell is respectively equipped with screwed hole, is provided with bolt in screwed hole.
The inner arc surface formation cavity of the bearing shell of two above-mentioned semicircle discharge rings.
Above-mentioned bolt passes respectively the screwed hole of two semicircle discharge rings, and two semicircle bearing shells that discharge ring are fastenedly connected.
Above-mentioned discharge tip is divergent shape.
Two above-mentioned semicircle discharge rings are respectively the aluminium alloy integral die-cast and form.
A kind of discharge ring of the present invention compared with prior art has the following advantages: because there is larger contact area bearing shell and gold utensil junction, can guarantee that thunder amplification current transfers to discharge tip from insulated conductor smoothly; Because the discharge ring is to be formed by the aluminum alloy materials integral die-cast, have good electric conductivity, can bear transfer and the requirement of dynamic and thermal stability performance of thunder amplification current; Because the discharge ring connects together bearing shell and discharge tip by discharge annulus, axle bar, wheel shaft etc., have very strong mechanical performance, can lower again weight simultaneously; Because discharge encircles, many outstanding discharge tip are arranged, thereby make the thunderbolt critical flashover voltage of compound strain insulator more stable reliable; Due to after discharge ring supports the use together with arcing ring, increase suspended insulated guide wire and kept away the function that is subjected to lightning-caused breaking, and easy construction of the present invention, flexible, only need simple training just can operate, simultaneously can be as requested, adjust flexibly discharging gap, satisfy the requirement of different use occasions, with low cost.
Description of drawings
Fig. 1 is the overall structure schematic diagram of gamut discharge ring of the present invention.
Embodiment
Below in conjunction with accompanying drawing, by describing a better specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, gamut discharge ring comprises two semicircle discharge rings, and two semicircle discharge rings are respectively the aluminium alloy integral die-cast and form, each semicircle discharge ring comprises bearing shell 1, spoke 2, discharge annulus 3 and discharge tip 4, and bearing shell 1 is connected by spoke 2 between annulus 3 with discharging; Discharge annulus 3 outer periphery are provided with discharge tip 4, and discharge tip 4 is divergent shape.Bearing shell 1 is Ω shape, and the outer arc surface of bearing shell 1 is fixedly connected with an end of spoke 2.The two ends bossing of bearing shell 1 is respectively equipped with screwed hole 11, is provided with bolt 13 in screwed hole 11.The inner arc surface formation contact-making surface 12 of the bearing shell 1 of two semicircle discharge rings.Bolt 13 passes respectively the screwed hole 11 of two semicircle discharge rings, and two semicircle bearing shells 1 that discharge ring are fastenedly connected.
Installation method of the present invention and operation principle: on the gold utensil (this gold utensil end is the power supply load measuring) of already installed compound strain insulator, two semicircles are discharged ring sets on gold utensil, cavity 12 is connected with the gold utensil intimate, increased like this contact area, by the fastening bearing shell 1 of bolt 13, two semicircle discharge rings form an integral body, guarantee gamut discharge ring installation accurate positioning, fixation, using the same method fixes arcing ring on the other end gold utensil of compound strain insulator, form satisfactory discharging gap.Wrap up by button with special-purpose insulating cover on gamut discharge ring and arcing ring again, metal parts needn't be directly exposed in atmosphere, reached the requirement of insulating.Like this, when thunder and lightning high electrical breakdown discharging gap, lightning current discharges to arcing ring from discharge tip 4 discharges of gamut discharge ring, rather than original discharging on insulated conductor, insulated conductor is kept away be subjected to troubling of lightning-caused breaking thereby solved.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
