Advantage of the present utility model: 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 utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the utility model comprises 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.
