Description

Technical Field

[0001] The utility model relates to the technical field of insulation protection of isolating switches, in particular to an insulation protection device for isolating switches. Background Art

[0002] In the current distribution network system, equipment such as high-voltage disconnectors play a vital role. However, the traditional switch protection baffles equipped with these devices have a series of significant problems. First, these baffles are particularly complicated in terms of operation, which not only increases the burden on operators, but also may lead to operational errors. Secondly, the fragility of the locking mechanism makes it possible for the baffle to be accidentally unlocked under certain conditions, thereby reducing the protective effect. The installation and maintenance of traditional switch protection baffles usually require the use of live working vehicles or when the equipment is powered off. This not only increases the complexity and cost of the operation, but also may bring safety risks in actual operation, such as accidental startup of equipment and electric shock to personnel. The existing switch protection baffles cannot be adapted to disconnectors of different specifications, and there is a problem of low adaptability. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The implementation details of the technical solution of the embodiment of the utility model are described in detail below:

[0027] First of all, it should be noted that the insulation protection scheme for isolating switches proposed in the present invention can be applied to the relevant technical fields of insulation protection for isolating switches. Figure 3 As shown, Figure 3 This is a schematic diagram of the upper conductive block 3 and the lower conductive block 4 of a porcelain bottle device in an existing drop-out type fuse. If there are some conductors (such as wires, animals) between the upper conductive block 3 and the lower conductive block 4 so that the upper conductive block 3 and the lower conductive block 4 are conductively connected, it will bring serious conductive risks. Therefore, it is necessary to block the upper conductive block 3 and the lower conductive block 4 so that the upper conductive block 3 and the lower conductive block 4 are insulated.

[0028] The existing isolating switches all have fixed baffles, so there is a problem of limitation on the size of the baffles. When encountering some larger or smaller porcelain bottle devices, the baffles of fixed size are obviously unable to adapt. At the same time, the positional relationship between the two porcelain bottle devices of the drop-out type fuse may also change with the different specifications of the drop-out type fuse, resulting in the position distance between the two porcelain bottle devices. The existing isolating switch protection is obviously unable to adapt to the problem of inability to perform adaptive insulation protection due to the different specifications of the drop-out type fuse.

[0029] According to one aspect of the utility model, an insulating protection device for an isolating switch is provided, the device comprising: two insulating baffles 1, which are slidably connected to each other; the insulating baffle 1 comprises a limiting unit 11 and a rotatable baffle 12; the limiting unit 11 is arranged on the insulating baffle 1 and is detachably connected to the rotatable baffle 12; wherein, when the rotatable baffle 12 is connected to the limiting unit 11, an opening 2 is formed in the insulating baffle 1 for isolating an upper conductive block 3 and a lower conductive block 4 of a porcelain bottle device.

[0030] Specifically, Figure 1 As shown, the two insulating baffles 1 can be slidably connected, that is, when the position distance between the two porcelain bottle devices changes due to the different specifications of the drop-out fuses, the positions can be adapted by sliding the two insulating baffles 1. Compared with the fixed baffles for isolating switch protection in the prior art, the utility model can improve the adaptability of insulation protection.

[0031] Reference Figure 3 As shown, if there are some conductors (such as wires, animals) between the upper conductive block 3 and the lower conductive block 4 so that the upper conductive block 3 and the lower conductive block 4 are conductively connected, it will bring serious conductive risks. Therefore, it is necessary to block the upper conductive block 3 and the lower conductive block 4 so that the upper conductive block 3 and the lower conductive block 4 are insulated. Therefore, the utility model is provided on the insulating baffle 1 through a limiting unit 11, and is detachably connected to the rotatable baffle 12, that is, the rotatable baffle 12 is connected to the limiting unit 11. When the rotatable baffle 12 is connected to the limiting unit 11, an opening 2 for isolating the upper conductive block 3 and the lower conductive block 4 of the porcelain bottle device is formed in the insulating baffle 1, that is, the rotatable baffle 12 is inserted into the gap between the upper conductive block 3 and the lower conductive block 4, so that the conductor can be prevented from entering the gap between the upper conductive block 3 and the lower conductive block 4 to make the upper conductive block 3 and the lower conductive block 4 conductively connected.

[0032] In one embodiment of the utility model, the rotatable baffle 12 includes a rotating shaft 121, a limiting groove 122 and a main baffle 123, the main baffle 123 and the limiting groove 122 are respectively arranged at two ends of the rotatable baffle 12, the rotating shaft 121 is arranged on the insulating baffle 1, and the limiting groove 122 is detachably connected to the limiting unit 11; wherein, when the limiting groove 122 is connected to the limiting unit 11, the limiting unit 11 can fix the limiting groove 122, and the main baffle 123 moves to the gap between the upper conductive block 3 and the lower conductive block 4.

[0033] Specifically, the rotatable baffle 12 includes a rotating shaft 121, a limiting groove 122 and a main baffle 123, that is, the rotatable baffle 12 can be rotated through the rotating shaft 121. When insulation protection is not needed, the limiting groove 122 or the main baffle 123 is rotated, and the rotatable baffle 12 is rotated through the rotating shaft 121 to rotate to the desired position; similarly, when insulation protection is needed, the rotating shaft 121 can be rotated to the position of the gap between the upper conductive block 3 and the lower conductive block 4 to perform insulation protection.

[0034] Further, please refer to Figure 2 and Figure 3 As shown, because the upper conductive block 3 and the lower conductive block 4 need to be blocked, a circular baffle is required. The opening 2 formed in the utility model has a semicircular arc, which can be referred to Figure 3 As shown, the semicircular arc near the first limiting groove 1221 has blocked half of the gap between the upper conductive block 3 and the lower conductive block 4. Therefore, the gap between the entire upper conductive block 3 and the lower conductive block 4 can be blocked by rotating the main baffle 123 to the position of the other half of the gap.

[0035] In one embodiment of the present utility model, the limiting groove 122 includes a first limiting groove 1221 and a second limiting groove 1222, the first limiting groove 1221 is arranged at one end of the rotatable baffle 12 and is detachably connected to the limiting unit 11, and the second limiting groove 1222 is arranged at the center of the rotatable baffle 12 and is detachably connected to the limiting unit 11.

[0036] Specifically, the first limiting groove 1221 is located at one end of the rotatable baffle 12. The operator can rotate the first limiting groove 1221 to a corresponding position so that the limiting unit 11 can clamp the first limiting groove 1221. Similarly, when the first limiting groove 1221 rotates to a corresponding position, the limiting unit 11 can also clamp the second limiting groove 1222 that moves accordingly. At this time, the main baffle 123 will move to the gap between the upper conductive block 3 and the lower conductive block 4, so as to fix the position of the main baffle 123 and prevent the main baffle 123 from changing its position.

[0037] In one embodiment of the utility model, the limiting unit 11 includes a first limiting member 111, a second limiting member 112 and a third limiting member 113; the first limiting member 111 is arranged on the insulating baffle 1, and is detachably connected to the first limiting groove 1221, and the second limiting member 112 and the third limiting member 113 are both detachably connected to the second limiting groove 1222; wherein, when the main baffle 123 moves to the gap between the upper conductive block 3 and the lower conductive block 4, the first limiting member 111 can fix the first limiting groove 1221, and the second limiting member 112 and the third limiting member 113 can fix the second limiting groove 1222.

[0038] Specifically, when the main baffle 123 moves to the gap between the upper conductive block 3 and the lower conductive block 4, in order to prevent the position of the main baffle 123 from changing, the first limiting groove 1221 can be clamped by the first limiting member 111, and the second limiting groove 1222 can be clamped by the second limiting member 112 and the third limiting member 113, wherein the first limiting member 111, the second limiting member 112 and the third limiting member 113 can be specifically a buckle, that is, the first limiting groove 1221 and the second limiting groove 1222 are fixed by the buckle, so that the position of the main baffle 123 at one end of the rotatable baffle 12 does not change, thereby solving the problems of the locking mechanism being weak, easily affected by environmental factors, and difficult to install and maintain.

[0039] In an embodiment of the present utility model, the device further comprises a slide rail 13 , and the two insulating baffles 1 are connected via the slide rail 13 .

[0040] Specifically, the two insulating baffles 1 are connected by the slide rail 13, so that the two insulating baffles 1 can be moved along the direction of the slide rail 13 respectively. In this way, when the specifications of the drop-out fuse are different and the position distance between the two porcelain bottle devices changes, the position of the main baffle 123 can be adjusted by sliding the insulating baffle 1, so that the main baffle 123 can enter the gap between the upper conductive block 3 and the lower conductive block 4.

[0041] In an embodiment of the present invention, the device further comprises two silicone strips, and the two silicone strips are respectively arranged on the two insulating baffles 1 .

[0042] Specifically, silicone strips are respectively provided on the two insulating baffles 1 , and the silicone strips are used to distinguish the colors of the three phases.

[0043] In summary, the utility model is adapted to isolating switches of different specifications by slidably connecting the two insulating baffles 1, and when the rotatable baffle 12 is connected to the limiting unit 11, an opening 2 is formed in the insulating baffle 1 for isolating the upper conductive block 3 and the lower conductive block 4 of the porcelain bottle device, thereby insulating and blocking the upper conductive block 3 and the lower conductive block 4 of the porcelain bottle device, and avoiding the safety risks caused by the mutual conduction between the upper conductive block 3 and the lower conductive block 4. At the same time, the first limiting groove 1221 and the second limiting groove 1222 are fixed by the limiting unit 11, that is, the buckle, so that the position of the main baffle 123 at one end of the rotatable baffle 12 does not change, thereby solving the problems of the locking mechanism being weak, susceptible to environmental factors, and difficult to install and maintain.
