Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pole circuit breaker, specifically to a pole circuit breaker epoxy resin insulating cylinder. BACKGROUND

[0002] Chinese patent discloses: an integrated adjustable pole circuit breaker, its application number is: CN202310088598.3, from its Figure Two It can be seen from the above that although the reinforcing rib is increased, the current transformer and the insulating cylinder are integrated, and finally an integral insulating cylinder is formed. However, in the integrated structure, the role of the reinforcing rib is not to prevent cracking, but to better wrap the current transformer so that it can be completely wrapped inside. For the split structure of the current transformer and the insulating cylinder, the prior art does not use the reinforcing rib on the insulating cylinder, and in the long-term use process, the conductive column will crack the insulating cylinder, and the cracking position is between the cylindrical boss and the body, which will eventually cause the leakage or short circuit. Therefore, a pole circuit breaker epoxy resin insulating cylinder is needed, which can prevent the tensile force of the conductive column and the crack between the cylindrical boss and the body for the split structure of the current transformer and the insulating cylinder. SUMMARY

[0003] The utility model aims at providing a pole circuit breaker epoxy resin insulating cylinder.

[0004] To achieve this purpose, the utility model adopts the following technical scheme:

[0005] A pole circuit breaker epoxy resin insulating cylinder is provided, which comprises a body and a cylindrical boss. The body is provided with a reinforcing rib, the reinforcing rib is located at the bottom of the cylindrical boss, and the top of the reinforcing rib is fixedly connected with the cylindrical boss.

[0006] Further, the body, the cylindrical boss and the reinforcing rib are integrally formed.

[0007] Further, the bottom of the reinforcing rib extends to the bottom of the body.

[0008] Further, the body is cylindrical.

[0009] Further, the width of the reinforcing rib is 60mm-100mm.

[0010] Further, the diameter of the body is 120mm, and the width of the reinforcing rib 1b is 80mm.

[0011] The utility model has the advantages that the epoxy resin insulating cylinder is provided with a reinforcing rib, which increases the support for the bottom of the cylindrical boss and prevents the cylindrical boss and the body from being pulled apart downward. BRIEF DESCRIPTION OF DRAWINGS

[0012] In order to more clearly illustrate the technical scheme of the embodiments of the utility model, the following will be briefly introduced the drawings needed to be used in the embodiments of the utility model.

[0013] Figure One It is the front view of the utility model;

[0014] Figure Two It is the three-dimensional structure schematic view of the utility model;

[0015] In the drawing: 1, the main body; 1a, cylindrical boss; 1b, reinforcing rib; 2, current transformer; 3, conducting column. Specific implementation

[0016] The following will be further illustrated the technical scheme of the utility model by specific implementation and the drawings.

[0017] Among them, the drawing is only for example explanation, and the representation is only schematic diagram, and not physical drawing, and can not be understood as the limitation of the patent; in order to better illustrate the embodiments of the utility model, some components of the drawing will be omitted, enlarged or reduced, and not represent the size of actual product.

[0018] Referring to Figures One to Two The epoxy resin insulation cylinder for pole-mounted circuit breaker shown in the drawing, including the main body 1 and the cylindrical boss 1a, the conducting column 3 is inserted into the cylindrical boss 1a, the main body 1 is provided with the reinforcing rib 1b, the reinforcing rib 1b is located at the bottom of the cylindrical boss 1a, and the top of the reinforcing rib 1b is fixedly connected with the cylindrical boss 1a. By being provided with the reinforcing rib 1b, the bottom support of the cylindrical boss 1a is increased, so that the cylindrical boss 1a and the main body 1 are not pulled apart downward. That is, by setting the reinforcing rib 1b, the current transformer 2 and the insulation cylinder of the split structure can be avoided, the tensile force of the conducting column 3 is avoided, and the crack between the cylindrical boss 1a and the main body 1 is avoided.

[0019] The main body 1, the cylindrical boss 1a and the reinforcing rib 1b are integrally formed. This integrally formed structure can be processed by injection molding, which is low in cost and easy to process.

[0020] The bottom of the reinforcing rib 1b extends to the bottom of the main body 1. In this way, the resin can flow better during injection molding, avoiding too many joints that cause the resin to flow unsmoothly.

[0021] The main body 1 is cylindrical.

[0022] The width of the reinforcing rib 1b is 60mm~100mm.

[0023] The diameter of the main body 1 is 120mm, and the width of the reinforcing rib 1b is 80mm. This ratio can better support the 120mm diameter of the insulation cylinder umbrella skirt inner ring.

[0024] The above merely preferred embodiments of the present application, it should be noted that for those of ordinary skill in the art, without departing from the technical principles of the present application, can make several improvements and variations, these improvements and variations should also be considered as the protection scope of the present application.
