Description

Insulating part for preventing partial discharge of high-voltage switch cabinet

Technical Field

The utility model belongs to the cubical switchboard auxiliary member relates to a prevention high tension switchgear partial discharge's insulating part.

Background

When the high-voltage switch cabinet runs, partial discharge easily occurs, and the practice shows that the partial discharge part is mainly the joint of a connecting pressing plate made of an organic insulating material and a steel material, including the joint between two insulating sleeves, the joint between a cabinet penetrating sleeve and a switch cabinet body and the like. In the prior art, an insulating gasket is additionally arranged at a joint, but air still exists in a gap between the insulating gasket and a connecting piece, so that a discharge phenomenon still exists, and the problem of partial discharge in a switch cabinet is not solved satisfactorily.

SUMMERY OF THE UTILITY MODEL

Based on above cubical switchboard partial discharge technical problem, the utility model provides a prevention high tension switchgear partial discharge's insulating part.

For solving the above technical problem, the utility model discloses a technical scheme as follows:

the utility model provides a prevent insulator of high tension switchgear partial discharge, it adopts flexible material, including integrated into one piece's tightening ring and lantern ring to the front of lantern ring inwards extends and forms the parcel ring.

Furthermore, the outer diameter of the tightening ring is smaller than that of the sleeve ring, and the inner diameter of the tightening ring is matched with the outer circumference of the cabinet penetrating sleeve.

Further, the tightening ring and the lantern ring are in right-angle transition.

Further, the inner space of the lantern ring is matched with the size of the connecting flange, so that the lantern ring can wrap the connecting flange.

Further, the tip of parcel ring has encircleed and has formed the inclined plane, and this inclined plane makes the tip of parcel ring attenuate gradually the beneficial effects of the utility model are as follows:

the utility model can insulate and obstruct the air gap in the connecting flange as a whole, and can also block and obstruct the switch cabinet opening gap at the position of the cabinet-through sleeve, so that the air gap which can generate the discharge phenomenon is eliminated, and the occurrence of the partial discharge phenomenon of the switch cabinet is prevented; the utility model discloses well whole flexibility is deformable, does benefit to parcel operation and shutoff operation, is favorable to isolated air gap, and the suitability is strong, has good result of use.

Detailed Description

For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.

As shown in fig. 1 to 5, an insulating member for preventing partial discharge of a high voltage switch cabinet is made of a flexible material, preferably a silicone material, so that the insulating member can wrap a connecting flange, and includes an integrally formed tightening ring 1 and a collar 2, and the front surface of the collar 2 extends inwards to form a wrapping ring 3, so that the whole insulating member can be wrapped on the connecting flange 6, the connecting flange connects a cabinet penetrating sleeve 4 and an insulating sleeve 5 together, and the cabinet penetrating sleeve 4 penetrates through the high voltage switch cabinet.

Further, as shown in fig. 2 and 4, the outer diameter of the tightening ring 1 is smaller than the outer diameter of the sleeve ring 2, and the inner diameter is set to match the outer circumference of the cabinet-through sleeve 4, so that the tightening ring 1 can be attached to the outer circumference of the cabinet-through sleeve 4; and the tightening ring 1 and the lantern ring 2 are in right-angle transition.

Further, as shown in fig. 2 and 3, the inner space of the collar 2 is configured to match the size of the connecting flange 6, so that the collar 2 can wrap the connecting flange 6 therein, and the front surface of the collar 2 faces inwards and is further provided with the wrapping ring 3, so that the collar 2 cannot easily slip off the connecting flange 6.

Further, as shown in fig. 2, the end of the wrapping ring 3 is surrounded to form an inclined surface 31, and the inclined surface 31 makes the end of the wrapping ring 3 become thinner gradually, which facilitates the wrapping operation and tight wrapping.

When the utility model is used, as shown in fig. 5, the insulating part is sleeved on the periphery of the cabinet-wearing sleeve 4, wherein the tightening ring 1 of the insulating part is attached on the periphery of the cabinet-wearing sleeve 4, the lantern ring 2 wraps the connecting flange 6, the wrapping ring 3 of the insulating part is attached on the surface of the connecting flange, and further the gap in the connecting flange 6 is wrapped in the wrapping ring, so that air ionization discharge in the gap is prevented; then will wear cabinet sleeve pipe 4 and remove to high tension switchgear's the trompil department that link up for tighten up ring 1 will be lived the trompil, with will wear the clearance shutoff of cabinet sleeve pipe 4 and trompil department, and then prevented the air ionization in the clearance and discharged.

The embodiment of the present invention is the above. The specific parameters in the above embodiments and examples are only for the purpose of clearly showing the verification process of the present invention, and are not used to limit the patent protection scope of the present invention, which is still subject to the claims, and all the equivalent structural changes made by using the contents of the specification and the drawings of the present invention should be included in the protection scope of the present invention.
