Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
In one embodiment, as shown in fig. 1, an adjustable insulation assembly 10 is provided that includes at least two main insulation panels 11. The main insulating plate 11 is provided with a first slot 111, the first slot 111 penetrates through two side surfaces of the main insulating plate 11 along a thickness direction of the main insulating plate 11, and the first slot 111 extends from an end surface of the main insulating plate 11 to the inside of the main insulating plate 11 in the first direction. In other words, the main insulating plate 11 can be inserted onto the insulating support 20 through the first insertion groove 111 in a radial direction of the insulating support 20, such that both ends of the final insulating support 20 are located at both sides of the main insulating plate 11, respectively.
The insulating support member 20 may be a porcelain arm, a pin insulator, or an insulating support portion in an isolating switch. In practical applications, the number of the insulating supports 20 on the tower may be multiple, and there may be multiple spacing between the insulating supports 20.
Based on this, as shown in fig. 1, in one embodiment, each main insulating plate 11 can move relatively in a second direction, so as to adjust the distance between the first slots 111 on different main insulating plates 11, wherein the first direction is not parallel to the second direction. In other words, when the main insulating plate 11 and the main insulating plate 11 are relatively moved, the pitch between the first slots 111 on the two main insulating plates 11 is changed in synchronization.
Therefore, in the using process, the main insulating plate 11 can be adjusted according to the distance between the insulating supports 20, so that the first slots 111 correspond to the insulating supports 20 one by one. The adjustable insulation assembly 10 described herein is thus applicable regardless of the spacing between the insulation supports 20. The application range and the universality of the adjustable insulation component 10 are enlarged. After the first slots 111 and the insulating support members 20 are in one-to-one correspondence, the adjustable insulating assemblies 10 are inserted into the insulating support members 20 along the first direction, so that the insulating support members 20 are respectively located in the first slots 111, and the main insulating plate 11 shields the two ends of the insulating support members 20 on the two sides of the main insulating plate 11, so that an operator cannot touch a live part and a grounding part at the same time no matter the operator is located on one side of the live part or on one side of the grounding part in the maintenance process, and the situation of electric shock and short circuit of the operator is avoided.
Specifically, as shown in fig. 1, the number of the main insulating plates 11 may be two. As shown in fig. 4, during use, the two insulating supports 20 are respectively inserted into the first slots 111 of the two main insulating plates 11. The adjustable insulation assembly 10 formed by combining two main insulation plates 11 shields both ends of each insulation support 20 at both sides of the adjustable insulation assembly 10.
Further specifically, in one embodiment, as shown in fig. 1, the first direction is perpendicular to the second direction. The first insertion groove 111 is disposed in a direction perpendicular to the moving direction of the main insulating plate 11. For example, in fig. 1, the moving direction between the main insulating plates 11 is a lateral direction, and the arrangement direction of the first insertion groove 111 is a longitudinal direction.
Further, in an embodiment, a first handle 114 is provided on the main insulating plate 11, and an operator adjusts the relative position between the two main insulating plates 11 by acting on the main insulating plate 11 through the first handle 114.
Further specifically, in one embodiment, the main insulating plates 11 at the two ends in the first direction are provided with the first handles 114, and the first handles 114 are located on the edges of the main insulating plates 11 far from the adjacent main insulating plates 11. Therefore, an operator can act on the first handles 114 at two ends respectively by two hands, and the operation is more convenient by adjusting the moving position between the main insulating plates 11 by pushing and pulling.
As shown in fig. 1, the adjustable insulation assembly 10 includes two main insulation plates 11, wherein one main insulation plate 11 is a first insulation plate, and the other main insulation plate 11 is a second insulation plate. The first handle 114 on the first insulating plate is located at the edge away from the second insulating plate, and the first handle 114 on the second insulating plate is located at the edge away from the first insulating plate.
Further, in one embodiment, as shown in fig. 1, adjacent main insulating plates 11 are at least partially overlapped, and a sliding fit structure is provided at the overlapped portion, by which the respective main insulating plates 11 are relatively slid in the second direction. In other words, although the main insulating plates 11 can slide relative to each other in the second direction, the adjacent main insulating plates 11 always have an overlapping portion therebetween, and a disconnection between the two main insulating plates 11 does not occur. Therefore, each main insulating plate 11 forms a complete insulating protection screen, and the charged part and the grounding part are respectively shielded at two sides of the insulating protection screen. The situation that the charged part or the grounding part is exposed due to the gap between the adjacent main insulating plates 11 is avoided.
Optionally, in an embodiment, the main insulating plates 11 may be slidably connected to each other through other intermediate structures. In other words, the respective main insulating plates 11 may be in direct contact with each other without overlapping, but indirect contact may be achieved through an intermediate structure. However, in this case, the main insulating plates 11 may be connected to each other by a pleated insulating fabric or the like, so that no gap is formed between the insulating plates, and the short circuit and electric shock caused by an operator touching a live piece or a ground piece exposed from the gap are avoided. The pleated insulating cloth can be expanded and contracted with the relative movement between the main insulating plates 11.
Further specifically, in one embodiment, as shown in fig. 1, the sliding fit structure includes a first fitting portion 112 provided on the first insulating plate and a second fitting portion 113 provided on the second insulating plate, the first fitting portion 112 is in sliding fit with the second fitting portion 113, and the second fitting portion 113 is provided along the second direction.
When the first insulating plate moves in the second direction with respect to the second insulating plate, the first fitting portion 112 moves in the second direction in the second fitting portion 113. The first insulating plate and the second insulating plate are in a sliding connection state by the fitting between the first fitting portion 112 and the second fitting portion 113.
Specifically, the second mating portion 113 may be a mating recess, and the first mating portion 112 may be a mating protrusion, the mating protrusion being located in the mating recess, the mating recess being disposed along the second direction. Or, the first fitting portion 112 is a fitting recess, the second fitting portion 113 is a fitting protrusion, the fitting protrusion is located in the fitting recess, and the fitting protrusion is arranged along the second direction.
For example, as shown in fig. 1, in one embodiment, the mating recess is a runner provided on the second insulating plate, the runner being provided in the second direction. The matching protrusion is a screw arranged on the first insulating plate, and the screw is positioned on the side surface, facing the second insulating plate, of the first insulating plate. And the nut of the screw is limited on the side surface of the second insulating plate departing from the first insulating plate.
Under the limiting effect of the screw, the first insulating plate and the second insulating plate cannot fall off. Meanwhile, under the guiding action of the sliding groove, the screw can slide along the second direction, so that the distance between the two first slots 111 is adjusted.
Further, in one embodiment, as shown in fig. 1, the number of the sliding fit structures is at least two, and each of the sliding fit structures is arranged at intervals in the first direction. The guide stability is improved, and meanwhile, the connection between the main insulating plates 11 is more reliable.
In order to improve insulation reliability, the first engagement portion 112 and the second engagement portion 113 are both insulating members. Specifically, the screw is made of an insulating material.
Further, as shown in fig. 2, in an embodiment, the adjustable insulation assembly 10 further includes an auxiliary insulation plate 12, and the auxiliary insulation plate 12 is provided with a second slot 121. The second insertion groove 121 penetrates both side surfaces of the auxiliary insulating plate 12 in the thickness direction of the auxiliary insulating plate 12, and the second insertion groove 121 extends from the end surface of the auxiliary insulating plate 12 to the inside of the auxiliary insulating plate 12 in the third direction. Like the first slot 111 of the main insulating plate 11, the auxiliary insulating plate 12 can be inserted into the insulating support 20 through the second slot 121, and both ends of the insulating support 20 are respectively blocked at both sides. However, when the auxiliary insulating plate 12 is inserted into the insulating support member 20, each insulating support member 20 is located in the second slot 121, which is different from the way in which each insulating support member 20 is inserted into the different first slots 111. The length of the second slot 121 in the third direction is not less than the distance between the two first slots 111 which are farthest away, and the third direction is not parallel to the first direction.
In use, after each of the main insulating plates 11 is inserted into each of the insulating supports 20, the auxiliary insulating plates 12 are inserted into all the insulating supports 20 in the third direction. As shown in fig. 3 and 4, when the auxiliary insulating plate 12 is disposed, the respective insulating supports 20 sequentially enter the second insertion groove 121. Finally, the first slot 111 and the second slot 121 are crossed to form a jack 13 through which only the insulating support 20 passes. The size of the insertion hole 13 can be matched with the smaller diameter part of the insulating support 20, in other words, the part between the shed and the shed on the general insulator is thinner, and the aperture of the insertion hole 13 can be matched with the thinner section, so that the adjustable insulating assembly 10 is located between the two sheds.
As shown in fig. 3 and 4, the third direction is the same as the first direction, and both directions are transverse.
Further, in one embodiment, as shown in fig. 1 and 2, the first slot 111 is a U-shaped slot, and the first slot 111 extends from the end surface of the main insulating plate 11 to the middle of the main insulating plate 11. So that the final insulating support 20 penetrates the middle of the main insulating plate 11, as shown in fig. 3 and 4.
As shown in fig. 2, in one embodiment, the second slot 121 is a U-shaped slot, and the second slot 121 extends to an edge of the auxiliary insulating plate 12 away from an opening of the second slot 121. Since the second insertion groove 121 needs to receive the insulating support 20, the length of the second insertion groove 121 is long.
Further, as shown in fig. 2 to 4, in one embodiment, a fixing clip 123 is disposed on the main insulating plate 11, and the fixing clip 123 can be clipped on the main insulating plate 11. As shown in fig. 3 and 4, after the main insulating plate 11 and the auxiliary insulating plate 12 are both mounted in place, the main insulating plate 11 and the auxiliary insulating plate 12 are clamped by the fixing clip 123, and the relative position between the two is kept fixed.
Further, as shown in fig. 2, a second handle 122 is disposed on the auxiliary insulating plate 12, and the second handle 122 is located on an end surface of the auxiliary insulating plate 12 parallel to the second slot 121. In other words, in the angle shown in fig. 2, the second slot 121 is arranged in the transverse direction, and the second handle 122 is located on the upper end surface of the auxiliary insulating plate 12.
The side of each insulation board in this application means the great two sides of area in the plate, and the terminal surface means around the face around the side.
Further, in another embodiment, an insulation shielding method for the insulation support 20 is provided, which employs the adjustable insulation assembly 10, and the insulation shielding method includes the following steps:
moving each main insulating plate 11 along a first direction, so that the first slots 111 on each main insulating plate 11 correspond to each insulating support member 20 one by one, and inserting each main insulating plate 11 onto each insulating support member 20 along the radial direction of the insulating support member 20, so that each insulating support member 20 is located in each first slot 111;
the auxiliary insulating plate 12 is inserted onto the insulating supports 20 in a third direction such that each of the insulating supports 20 is positioned in the second insertion groove 121.
The above-mentioned scheme provides an insulating direction of shielding for insulating support member 20, can adjust each said main insulating board 11 according to the interval between each insulating support member 20 for each said main insulating board 11 on first slot 111 respectively with each insulating support member 20 one-to-one, thereby enlarge application scope. After the main insulating plate 11 is inserted into the insulating support 20, the auxiliary insulating plate 12 is inserted into the insulating support 20 along the third direction, and finally the first slot 111 and the second slot 121 are intersected to form the insertion hole 13 through which only the insulating support 20 passes, and other parts are shielded, so that a high insulating shielding effect is achieved.
