Technical field
The present invention relates to a kind of shaft tower arrangement kind, especially a kind of cable termination shaft tower arrangement, specifically a kind of shaft tower arrangement that is used to improve cable termination safety belongs to the technical field of electric power safety.
Background technology
110kV and above high-tension cable are used rapid the rising in recent years, and cable fault quantity is also rising year by year, and a lot of high-tension cable accidents have taken place in many areas, and the requirement of strengthening quality control, minimizing cable fault rate is extremely urgent.
At present, the cable line design mainly contains multiple modes such as single loop, double loop, Two bors d's oeuveres and Two bors d's oeuveres double loop, the design that cable termination under the various different modes is arranged is of all kinds, existence influences each other the spatial placement of each parts such as cable termination is alternate, the terminal stress cone is connected with lightning arrester, downlead to Electric Field Distribution, and design did not take into full account this point in the past.Theoretically with each department practical operation situation analysis at present, each parts is in the mode difference of spatial placement, not only directly influence the safe operation of each parts, but also after a certain unit failure can take place, all can produce the secondary injury miscellaneous part or whole cable system.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of cable termination shaft tower arrangement is provided, it is simple and compact for structure, and is easy to install, and insulation effect is good, and is stable, safe and reliable.
According to technical scheme provided by the invention, described cable termination shaft tower arrangement comprises the circuit tower and is positioned at the cable termination shaft tower of described circuit tower one side; Described cable termination shaft tower is provided with mounting panel, and described mounting panel is installed with lightning arrester and tag, and the distance L between described tag and lightning arrester is 1 ~ 1.5m.
Described lightning arrester is provided with arrester discharge counter.Described lightning arrester is the dropout type lightning arrester.Described circuit tower is provided with strain insulator string.
Be installed with cross-arm formula synthetic insulator on the described circuit tower, described cross-arm formula synthetic insulator is provided with the lead fixed wire clamp corresponding to the other end that links to each other with the circuit tower.
Described mounting panel is provided with the terminal earth brace that is used for tag ground connection.Described terminal earth brace is provided with ground connection case and protective sleeve.
Advantage of the present invention: the cable termination shaft tower is provided with mounting panel, be installed with lightning arrester and tag on the mounting panel, distance L between lightning arrester and tag is set to 1 ~ 1.5m, can reduce the field strength distribution in the tag, reduced the land resource that takies, insulation effect is good, and is stable, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the present invention includes strain insulator string 1, cross-arm formula synthetic insulator 2, lightning arrester 3, lead fixed wire clamp 4, circuit tower 5, tag 6, ground connection case 7, protective sleeve 8, arrester discharge counter 9, mounting panel 10, cable termination shaft tower 11 and terminal earth brace 12.
The cable termination reliability service must be considered the requirement that external insulation requirement, lightning protection requirement, mechanical performance requirement and convenient repairing are safeguarded, whether the main foundation of external insulation performance is for satisfying the corona discharge that does not produce under dry and the wet condition under this arrangement; Lightning protection requires main according to whether effectively protecting cable termination for lightning arrester; Mechanical performance requires according to for whether satisfying job requirement when growing, satisfying under the prerequisite of these conditions, optimum organization, thereby reach the cable termination design and installation is being satisfied under the prerequisite of service conditions, taken into account and take still less land resource, help promoting installation quality, be convenient to install, repairing is safeguarded and requirement such as antitheft, protection against the tide.
As shown in Figure 1: described cable termination shaft tower 11 is positioned at a side of circuit tower 5; the end of described cable termination shaft tower 11 is provided with fixedly connected mounting panel 10; be installed with lightning arrester 3 and tag 6 on the described mounting panel 10; the distance L that described tag 6 and lightning arrester are 3 is 1 ~ 1.5m; can effectively reduce the land occupation resource; can reduce simultaneously the electric-field intensity distribution in the tag 6, the security of operation of protective circuit terminal fitting 6.Lightning arrester 3 is provided with arrester discharge counter 9, the maintenance of lightning arrester 3 for convenience, and lightning arrester 3 is selected the dropout type lightning arrester.
Described circuit tower 5 is provided with strain insulator string 1, and the below of described strain insulator string 1 is provided with cross-arm formula synthetic insulator 2, and described strain insulator string 1 is all fixedlyed connected with circuit tower 5 with cross-arm formula synthetic insulator 2.Cross-arm formula synthetic insulator 2 is provided with lead fixed wire clamp 4 corresponding to the other end end that links to each other with circuit tower 5.Also be provided with the terminal earth brace 12 that is used for tag 6 is carried out ground connection on the cable termination shaft tower 11, described terminal earth brace 12 is provided with ground connection case 7 and protective sleeve 8.
As shown in Figure 1: the distance relation that tag 6 and lightning arrester are 3 adopts finite element analysis software to analyze, when the distance of 3 of tag 6 and lightning arresters is 1 ~ 1.5m, 3 of Chang Gui tag 6 and lightning arresters apart from 2m relatively, can effectively reduce the occupation of land resource, simultaneously, can reduce the field strength distribution of tag 6.During concrete enforcement: the diameter that increases grading ring or expansion lead-out wire radome at cable termination lead-out wire place; Recommend lightning arrester 3 to be arranged in a side near lightning surge intrusion, promptly when lightning wave is invaded, should be able to make lightning wave earlier on the arrival lightning arrester 3, the earth terminal of lightning arrester 3 is answered independent grounding, ground connection again after not recommending lightning arrester 3 and cable jacket being connected.In engineering reality, consider that in the busy section of town insulator produces blast and hurts sb.'s feelings recommendation employing composite sheath cable termination when generation punctures.The cable termination body is fixedly the time, at the scene under the situation of conditions permit, should keep a straight line, avoid crooked as far as possible, thereby the quality of guaranteeing the cable termination pole and tower foundation during this external design and installation especially along the river, prevent from along bridge and other places, causes oil impregnate, cracking defect to avoid the long-term affected by force of cable termination afterbody.
