Abstract
The utility model relates to a windage yaw prevention insulator. Problems of troublesome processing, high processing cost and easy breaking of an insulating rod of an existing windage yaw prevention insulator are mainly solved. The windage yaw prevention insulator comprises a connecting flange (1), an insulating rod (2), a connecting head (3), rubber umbrella covers (4) and an equalizing ring (5). The connecting flange (1) and the connecting head (3) are respectively provided with a first sleeve (6) and a second sleeve (7). The windage yaw prevention insulator is characterized in that the insulating rod (2) and the first sleeve (6) are in interference fit and the insulating rod (2) and the second sleeve (7) are in interference fit, both the inner walls of the first sleeve (6) and the second sleeve (7) are provided with uniform fine teeth (8). According to the windage yaw prevention insulator, the interference fit connection is employed, and the windage yaw prevention insulator has the advantages of convenient processing, low processing cost and high strength of the insulating rod.
Description
Technical field
The utility model relates to a kind of electric armour clamp, is specifically related to a kind of anti-windage yaw insulator.
Background technology
In the high-pressure delivery circuit, the windage yaw discharge is to influence one of problem of line security operation always.In order to prevent the windage yaw discharge, on shaft tower, all fix anti-windage yaw insulator, be used for supporting the transition of wire jumper section.Existing anti-windage yaw insulator mainly is made up of adpting flange, insulating rod, connector, rubber umbrella cover and grading ring, adpting flange and connector are separately fixed at the two ends of insulating rod, be equipped with sleeve on adpting flange and the connector, present fixed form is as follows: 1, insulating rod is inserted in adpting flange and the connector, fixes by the pin of radial penetration then; 2, process internal thread in the sleeve on adpting flange and connector, add external screw thread at the two ends of insulating rod, between insulating rod and adpting flange and the connector respectively by being threaded.There is following technological deficiency in two kinds of above-mentioned connected modes: 1, machining screw or hole cumbersome, the processing cost height; 2, have minim gap between insulating rod and the adpting flange and between insulating rod and the connector, can cause interface fatigue impaired when using for a long time, insulating rod is easily fractureed in the junction, useful life is short.
The utility model content
In order to overcome the deficiency of existing anti-windage yaw insulator processing trouble, processing cost height and insulating rod frangibility, the utility model provides a kind of anti-windage yaw insulator, should prevent that the windage yaw insulator adopted interference fit to connect, and have and be convenient to processing, the low insulating rod advantages of high strength that reaches of processing cost.
The technical scheme that the utility model adopts is: a kind of anti-windage yaw insulator, comprise adpting flange, insulating rod, connector, rubber umbrella cover and grading ring, be respectively equipped with first sleeve and second sleeve on adpting flange and the connector, between insulating rod and first sleeve and be interference fit between insulating rod and second sleeve, the inwall of described first sleeve and second sleeve is equipped with closely-pitched.
The port outer wall of described first sleeve and second sleeve and inwall are respectively equipped with annular groove and heavy mouth.
The beneficial effects of the utility model are: owing to take technique scheme, adding man-hour, the diameter dimension of control insulating rod and the internal diameter size of first sleeve and second sleeve, the external diameter that makes the insulating rod two ends forms the size relationship of interference fit respectively with the internal diameter of first sleeve and second sleeve, during assembling, adpting flange and connector are heated, adpting flange and connector expanded by heating, the internal diameter of first sleeve and second sleeve increases, be inserted into insulating rod in first sleeve and second sleeve this moment, namely form interference fit after the cooling and connect, closely-pitched is embedded in the insulating rod, and it is more firm that insulating rod is connected.Owing between insulating rod and first sleeve and do not have relative motion between insulating rod and second sleeve, so can not produce fatigue damage between insulating rod and adpting flange and the connector, have be convenient to processing, processing cost is low and the insulating rod advantages of high strength.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-adpting flange among the figure, 2-insulating rod, 3-connector, 4-rubber umbrella cover, 5-grading ring, 6-first sleeve, 7-second sleeve, 8-closely-pitched, 9-annular groove, heavy mouthful of 10-.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of anti-windage yaw insulator, comprise adpting flange 1, insulating rod 2, connector 3, rubber umbrella cover 4 and grading ring 5, be respectively equipped with first sleeve 6 and second sleeve 7 on adpting flange 1 and the connector 3, between insulating rod 2 and first sleeve 6 and be interference fit between insulating rod 2 and second sleeve 7, the inwall of described first sleeve 6 and second sleeve 7 is equipped with closely-pitched 8.Owing to take technique scheme, adding man-hour, the diameter dimension of control insulating rod 2 and the internal diameter size of first sleeve 6 and second sleeve 7, the external diameter that makes insulating rod 2 two ends forms the size relationship of interference fit respectively with the internal diameter of first sleeve 6 and second sleeve 7, during assembling, adpting flange 1 and connector 3 are heated, adpting flange 1 and connector 3 expanded by heating, the internal diameter of first sleeve 6 and second sleeve 7 increases, be inserted into insulating rod 2 in first sleeve 6 and second sleeve 7 this moment, namely form interference fit after the cooling and connect, closely-pitched 8 is embedded in the insulating rod 2, and it is more firm that insulating rod 2 is connected.Because between insulating rod 2 and first sleeve 6 and do not have relative motion between insulating rod 2 and second sleeve 7, therefore can not produce fatigue damage between insulating rod 2 and adpting flange 1 and the connector 3, have and be convenient to processing, the low insulating rod advantages of high strength that reaches of processing cost.
The port outer wall of described first sleeve 6 and second sleeve 7 and inwall are respectively equipped with annular groove 9 and heavy mouth 10.During cast rubber umbrella cover 4, fill up annular groove 9 and heavy mouth 10, make being connected firmly of rubber umbrella cover 4 and first sleeve 6 and second sleeve 7.
Claims (2)
1. anti-windage yaw insulator, comprise adpting flange (1), insulating rod (2), connector (3), rubber umbrella cover (4) and grading ring (5), be respectively equipped with first sleeve (6) and second sleeve (7) on adpting flange (1) and the connector (3), it is characterized in that: be interference fit between insulating rod (2) and first sleeve (6) and between insulating rod (2) and second sleeve (7), the inwall of described first sleeve (6) and second sleeve (7) is equipped with uniform closely-pitched (8).
2. a kind of anti-windage yaw insulator according to claim 1 is characterized in that: the port outer wall of described first sleeve (6) and second sleeve (7) and inwall are respectively equipped with annular groove (9) and heavy mouthful (10).
