Abstract
The utility model discloses an insulated bearer for a breaker. The insulated bearer comprises a body and connecting pieces arranged inside of the body. The body consists of a cylinder body and an umbrella skirt which is arranged on the outer periphery of the cylinder body, distributed at intervals along the axial direction of the cylinder body, and capable of increasing the creepage distance. The connecting pieces are arranged on the end surfaces at the two ends of the cylinder body. On the basis of guaranteeing the insulation strength and mechanical strength of the body and on the premise of maintaining the size of a conventional insulated bearer, the umbrella skirt is capable of increasing the creepage distance of the insulated bearer, thereby decreasing the risk of surface breakdown of the insulated bearer in a high-voltage, narrow, and enclosed space.
Description
Technical field
The utility model relates to the inner insulated leg that plays the insulating supporting effect of a kind of circuit breaker, belongs to breaker technical field.
Background technology
For some high pressure enclosed type electric apparatus, such as circuit breaker, the general parts that play the insulating supporting effect that adopt insulated leg to use as its inside, the insulation level of insulated leg and the strength of materials directly affect the performance and used life of circuit breaker, and insulated leg also will be beneficial to the connection of its adjacent component (such as terminal block, instrument transformer) on the basis that guarantees insulation level, therefore, the performance requirement to insulated leg is also higher.The inner used insulated leg of domestic existing circuit breaker adopts tubular structure mostly, because the inner space of circuit breaker is narrow and small, and electric pressure is higher, and the problem of surface breakdown easily occurs the outer face within it.
The utility model content
The purpose of this utility model provides a kind of circuit breaker insulated leg that can reduce self surface breakdown danger.
The utility model adopts following technical scheme: a kind of circuit breaker insulated leg, comprise body and be arranged on intrinsic connector, described body is by cylinder and be arranged on consisting of to the spaced apart full skirt that can increase creepage distance along cylinder axis on the cylinder outer peripheral face, and described connector is located on the end face at cylinder two ends.
Described body adopts the cast of castable material one to form.
Described connector is for being inlaid in respectively the embedded component with internal thread in the described cylinder both ends of the surface.
Adopt the circuit breaker insulated leg of said structure, because body is by cylinder and be arranged on consisting of to spaced apart full skirt along cylinder axis on the cylinder outer peripheral face, on the basis of guaranteeing body dielectric strength and mechanical strength, and under the prerequisite that does not change existing insulated leg size, full skirt can increase the creepage distance of insulated leg, thereby is reduced in the danger of insulated leg surface breakdown in high voltage, the narrow and small confined space.
Description of drawings
Fig. 1 is example structure schematic diagram of the present utility model;
Fig. 2 is the cutaway view of Fig. 1.
Embodiment
The utility model circuit breaker embodiment of insulated leg: as shown in Figure 1 and Figure 2, comprise body 1, body is made of cylinder 11 and the full skirt 12 of arranging along its axially spaced-apart that is wholely set on cylinder 11 outer peripheral faces, full skirt 12 can increase the creepage distance of whole insulated leg, be embedded with respectively the embedded component 2 with internal thread in the both ends of the surface of cylinder 11, can make things convenient for like this bearing to adopt the mode that is threaded to be connected with other part (such as terminal block, the instrument transformer of circuit breaker).
Body 1 adopts the cast of pourable insulating material (such as insulating material such as DMC, SMC, epoxy resin) one to form, and embedded component 2 embeds in the body casting process, improved the production efficiency of whole insulated leg, and under the prerequisite that guarantees mechanical strength, saved raw material, reduced cost.
Above-described embodiment in use, can be according to actual needs, adopt simultaneously 3-6 insulated leg that the electric devices such as instrument transformer are supported, guarantee dielectric strength thereby reach on the basis of the mechanical strength that guarantees the requirements such as assembling, transportation, installation, avoid surface breakdown.
