Abstract
A kind of insulating cylinder, conducting rod is arranged with in the cylindrical barrel of hollow, stack shell is evenly equipped with louvre I, a flange is respectively set at the two ends of cylindrical shell, described flange is truncated cone-shaped, multiple louvre II is evenly equipped with in the side of flange, and through fixing hole is set between the bottom surface of louvre II and flange stub end, and by bolt, flange stub end is fixed on one end of cylindrical shell, the edge of the little head end of flange is provided with multiple steady pin, be located in the pin-and-hole at cylindrical shell other end edge to insert, described steady pin side is parallel is provided with multiple circular protrusion around steady pin, and imbed the little head end of flange.The utility model, by arranging the flange with heat sinking function at insulating cylinder cylindrical shell two ends, improves the heat dispersion of insulating cylinder in prior art, to ensure that the insulation property of insulating cylinder are not by the impact of high heat.
Description
Technical field
The utility model belongs to equipment for power transmission and distribution field, especially relates to a kind of insulating cylinder for circuit breaker in GIS.
Background technology
GIS is gas-insulated switchgear, it is by the equipment in a transformer station except transformer, comprise circuit breaker, isolating switch, earthed switch, voltage transformer, current transformer, lightning arrester, bus, cable termination, inlet-outlet sleeve etc., be organically combined into an entirety through optimal design.
In GIS; circuit breaker is the key ensureing whole equipment and circuit Electrical Safety; in circuit breaker; every phase arc control device have independently insulating cylinder; insulating cylinder, while the insulation property keeping nominal situation circuit breaker, usually also will tolerate the erosion of the high temperature and high pressure gas produced when circuit breaker cut-offs abnormal current and not destroy its insulation property.But the structure of current insulating cylinder is unsatisfactory in heat radiation, under the prerequisite ensureing insulation property, effectively can not play the effect of heat radiation.
Utility model content
The purpose of this utility model is to provide a kind of insulating cylinder, by arranging the flange with heat sinking function at cylindrical shell two ends, improves the heat dispersion of insulating cylinder in prior art, to ensure that the insulation property of insulating cylinder are not by the impact of high heat.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of insulating cylinder, conducting rod is arranged with in the cylindrical barrel of hollow, stack shell is evenly equipped with louvre I, a flange is respectively set at the two ends of cylindrical shell, described flange is truncated cone-shaped, multiple louvre II is evenly equipped with in the side of flange, and through fixing hole is set between the bottom surface of louvre II and flange stub end, and by bolt, flange stub end is fixed on one end of cylindrical shell, the edge of the little head end of flange is provided with multiple steady pin, be located in the pin-and-hole at cylindrical shell other end edge to insert, described steady pin side is parallel is provided with multiple circular protrusion around steady pin, and imbed the upper edge of flange.
Further, gauze screen is provided with between described flange and conducting rod.
Compared with prior art, the beneficial effects of the utility model are:
First, the utility model installs the flange of truncated cone-shaped respectively at the two ends of insulating cylinder, make the one end open flare opening of insulating cylinder, be conducive to the diffusion of the high temperature and high pressure gas produced in insulating cylinder, and the side of cylindrical shell two end flanges arranges multiple louvre II, match with the louvre I be arranged on stack shell, further increase the heat-sinking capability of insulating cylinder;
The second, the flange in the utility model is plugged in the pin-and-hole at insulating cylinder cylindrical shell edge by the steady pin being embedded in flange upper edge, realizes the connection of flange and cylindrical shell, easy for installation;
3rd, be provided with gauze screen between flange and conducting rod in the utility model, make the motion conductive component Electric Field Distribution of circuit breaker even, reduce the adverse effect of non-uniform electric field to equipment.

Fig. 2 is the profile of flange in the utility model.
Fig. 3 is partial enlarged drawing in the utility model.
Mark in figure: 1, cylindrical shell, 2, louvre I, 3, flange, 4, steady pin, 5, louvre II, 6, fixing hole, 7, circular protrusion.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
As shown in the figure, a kind of insulating cylinder, its cylindrical shell 1 is the cylindrical of hollow, the sheathed electrodes conduct bar in center, cylindrical shell 1 side is provided with multiple louvre I 2, the two ends of cylindrical shell 1 are connected with a truncated cone-shaped flange 3 respectively, one end of cylindrical shell 1 is connected with the little head end of flange 3, flare openings is formed after connection, the other end of cylindrical shell 1 is connected with the stub end of flange 3, the side of described flange 3 is uniformly distributed multiple trapezoidal louvre II 5, between the bottom surface of louvre II 5 and flange 3 stub end, through fixing hole 6 is set, be convenient to the one end by this fixing hole 6, the stub end of flange 3 being fixed by bolts to cylindrical shell 1, the uniform multiple steady pin 4 of the described little leading edge of flange 3, to be plugged in the pin-and-hole of cylindrical shell 1 other end, described steady pin 4 one end be arranged in parallel three circular protrusions 7 around steady pin, and be embedded in the little leading edge of flange 3, and between flange 3 and described electrodes conduct bar, gauze screen is set.
The insulating cylinder that the utility model provides, by arranging the flange 3 with heat sinking function at cylindrical shell 1 two ends, improves the heat dispersion of insulating cylinder in prior art, to ensure that the insulation property of insulating cylinder are not by the impact of high heat.
