[0002] In the field of power systems and industrial automation, disconnectors, as a key device, are mainly used to control the connection and disconnection of circuits to ensure the safe and stable operation of electrical equipment and power systems. With the continuous advancement of science and technology and the growing demand for electricity, traditional disconnectors have gradually failed to meet the requirements of modern power systems for efficiency, safety and reliability. The contact points of current rotary disconnectors are mostly exposed, and the arcs generated are directly exposed to the outside when closing and opening the switch, which may easily lead to safety hazards. At the same time, it is not convenient to protect the contact points after opening the switch, and it is easy to be contaminated by foreign matter such as dust from the outside, resulting in poor contact after closing the switch. Therefore, it is necessary to design a rotary disconnector. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1.

[0021] Embodiment 1
[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rotary isolating switch proposed by the utility model comprises a conductive arm 1, an insulator 2 and a support frame 4, a gear seat 3 is rotatably mounted on the top of the support frame 4, an insulator 2 is fixedly mounted on the top of the gear seat 3, a conductive arm 1 is fixedly mounted on the top of the insulator 2, a protective sleeve 9 is slidably mounted on the outer side of the conductive arm 1, a roller 902 is rotatably mounted on the outer side of the protective sleeve 9, a thrust spring 901 is fixedly connected between the protective sleeve 9 and the conductive arm 1, a rotating rod 8 is rotatably mounted on the top of the support frame 4 between the gear seats 3, a disc 801 is fixedly mounted on one end of the rotating rod 8, and transmission tooth plates 10 are movably connected to both sides of the disc 801 through movable rods 802.
[0023] The gear seat 3 and the support frame 4 are rotatably installed through the bearing seat 301, and the support frame 4 and the transmission gear plate 10 are slidably installed through the sliding frame 1001. The other end of the rotating rod 8 is fixedly installed with an operating disk 803, and the transmission gear plate 10 and the gear seat 3 are meshed with each other.
[0024] The working principle of the rotary isolating switch based on Example 1 is as follows: the operating disk 803 can be used to drive the rotating rod 8 to rotate, and the rotation of the rotating rod 8 can drive the disc 801 to rotate synchronously. One end of the movable rod 802 is eccentrically connected to the disc 801, so that when the disc 801 rotates, the movable rod 802 can be extended to both sides, and the movable rod 802 can be used to push the transmission tooth plate 10 to move synchronously to both sides. The sliding frame 1001 can limit the sliding of the transmission tooth plate 10 so that the transmission tooth plate 10 can move horizontally. The bearing seat 301 can be used to rotate the gear seat 3. When the transmission tooth plate 10 moves to both sides, The meshing relationship between the transmission tooth plate 10 and the gear seat 3 can be used to drive the gear seat 3 to rotate. When the gear seat 3 rotates, the conductive arm 1 can be indirectly driven to rotate synchronously through the insulator 2, so that the conductive arm 1 can be rotated 90°, and the two groups of conductive arms 1 can be rotated and separated, which is convenient for the opening operation. After the conductive arms 1 are separated, the thrust generated by the thrust spring 901 can be used to push the protective sleeve 9 to move, so that the contact end of the conductive arm 1 can be stored in the protective sleeve 9. The protective sleeve 9 can protect the contact end of the conductive arm 1 from being easily contaminated by foreign matter such as dust from the outside, so as to avoid poor contact caused by the obstruction of foreign matter after closing the switch, thereby effectively improving the use effect.
[0025] By driving the rotating rod 8 to rotate in the opposite direction, the transmission tooth plate 10 can be driven to close and move, and the gear seat 3 can be synchronously driven to rotate and reset in the opposite direction, and the conductive arm 1 can be driven to rotate and reset, so that the contact end of the conductive arm 1 can be closed and contacted, which is convenient for closing operation. When the conductive arm 1 is docked, the two protective sleeves 9 can be in contact with each other. Through the rolling action of the roller 902, the two protective sleeves 9 can be smoothly squeezed against each other, avoiding the situation where the protective sleeves 9 cannot be synchronously squeezed due to misalignment. When the protective sleeves 9 are squeezed against each other, the protective sleeves 9 can slide along the conductive arm 1, so that the conductive arm 1 can be smoothly closed. Through the action of the thrust spring 901, the two protective sleeves 9 can be in close contact, and the contact position of the conductive arm 1 when closing can be protected, which can effectively avoid the arc generated during closing from being directly exposed to the outside, effectively improving the safety effect.
[0026] Embodiment 2
[0027] like Figure 1 , Figure 2 , Figure 3As shown, a rotary isolating switch proposed by the utility model, compared with the first embodiment, this embodiment also includes: a grounding frame 6 is fixedly installed on the top of the support frame 4 at the rear end of the gear seat 3, a limiting groove 601 corresponding to the conductive arm 1 is opened on the inner side of the grounding frame 6, a grounding wire 602 extending from the support frame 4 is fixedly installed on the bottom of the grounding frame 6, the rotating rod 8 and the support frame 4 are rotatably installed through the shaft sleeve 7, the shaft sleeve 7 and the rotating rod 8 are fixed by a fixing bolt 701, and a fixing column 5 is fixedly installed on the bottom of the support frame 4, and the bottom of the fixing column 5 is fixedly connected with a bolt seat.
[0028] In this embodiment, Figure 1 and Figure 2 As shown, after the conductive arm 1 is driven to flip and open, the conductive arm 1 can be inserted into the limit groove 601. The limit groove 601 limits the conductive arm 1, so that the conductive arm 1 is not easy to shake after opening. At the same time, the conductive arm 1 is in contact with the grounding frame 6, which can facilitate the grounding operation. The grounding wire 602 is connected to the grounding frame 6 by telecommunication. By connecting the grounding wire 602 to the grounding device, the conductive arm 1 can be automatically grounded after opening, without manual grounding operation, which effectively improves the work efficiency. Figure 3 As shown, the shaft sleeve 7 can be used to support the rotating rod 8 so that the rotating rod 8 can be rotated smoothly. The fixing bolt 701 can fix the rotating rod 8 after rotation, which can prevent the rotating rod 8 from rotating. The conductive arm 1 can be fixed after closing and opening the switch. Figure 1 As shown, the support frame 4 can be supported by the fixing column 5, and by installing and fixing the fixing column 5 to the ground, the device can be conveniently fixed in a suitable position for use.
