Abstract
The utility model relates to electrical equipment, in particular to a lightning arrester grading ring convenient to maintenance. The grading ring comprises a ring body I and a metal top cover which is fixed to the ring body I by virtue of a connecting rod. A gap I is arranged at the ring body I. A protruding body of the ring body I is arranged at the ring body I which is arranged at two ends of the gap I. The sphere diameter of the protruding body of the ring body A and the protruding body of a ring body II is slightly larger than the section diameter of the ring body, which is beneficial to discharging. By arranging the gap at the ring body of the utility model, the grading ring is convenient to replace without cutting off lines. Meantime, by arranging the gap on the ring body, the grading ring has good effect and excellent performance.
Description
Technical field
The utility model relates to power equipment, specifically is that a kind of lightning arrester easy to maintenance is used grading ring.
Background technology
Be provided with grading ring on the existing lightning arrester, still, existing grading ring need carry out destructive procedure on grading ring when maintain and replace, like this, on the one hand, strengthened maintenance difficulty, and, also increased maintenance cost.
Existing grading ring exists not enough at aspect of performance, under the too big situation of voltage, and more fragile grading ring.
The utility model content
The technical problem that the utility model will solve provides a kind of grading ring easy to maintenance that is used on the lightning arrester.
The content of the utility model is that it comprises ring body I and through connecting rod and the fixing casting coping of ring body I, has a slit I on the said ring body I, and the ring body I that is positioned at I two ends, slit is provided with ring body I excrescence.
Said connecting rod is provided with ring body II, has a slit II on the ring body II, and the ring body II that is positioned at II two ends, slit is provided with ring body II excrescence.
The beneficial effect of the utility model is that the sphere diameter of ring body I excrescence of the utility model and ring body II excrescence is a bit larger tham the diameter of section of ring body, is beneficial to discharge.
The utility model need not cut off line through making when changing the utility model conveniently in that the slit is set on the ring body, and simultaneously, the slit is set on ring body can be so that the better effects if of the utility model, and performance is more excellent.
Description of drawings
