Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4As shown, an outdoor low-temperature resistant high-voltage disconnect switchgear includes a mounting base 1. Two high-voltage disconnect switch bodies 2 are respectively snapped onto the upper side of the mounting base 1. A round seat 3 is fixedly installed on the lower side of each of the two high-voltage disconnect switch bodies 2. Two symmetrically distributed connecting rods 4 are fixedly connected inside the mounting base 1. Displacement slide plates 5 are slidably connected to the outer surfaces of the two connecting rods 4. Positioning blocks 7 for fixing the round seats 3 are fixedly provided on one side of each of the two displacement slide plates 5. By setting the positioning blocks 7, the elastic force of the first connecting spring 6 can cause the two displacement slide plates 5 to drive the two positioning blocks 7 to extend and retract. When the two positioning blocks 7 move towards each other, the limit on the high-voltage disconnect switch can be released and the high-voltage disconnect switch can be disassembled, which is convenient to use.

[0026] Two first connecting springs 6 are fixedly installed between the two displacement slide plates 5. The interior of the mounting base 1 has four grooves 8. Each of the four grooves 8 is rotatably connected to a limiting screw block 9 for positioning the round seat 3. Both ends of the two round seats 3 have slots 10. One side of the limiting screw block 9 is engaged in the slot 10. The top of the interior of the mounting base 1 has two base plates 11. One side of each base plate 11 is engaged with an L-shaped clamping plate 12 for fixing the round seat 3.

[0027] The upper side of the mounting base 1 is provided with an array of mounting slots 14. Two telescopic rods 15 are slidably connected inside the mounting base 1. One side of the telescopic rod 15 passes through the mounting base 1 and extends to the upper side of the mounting base 1. A protective box 16 is fixedly installed on one side of the two telescopic rods 15. An inverted V-shaped plate 17 for covering the mounting slots 14 is fixedly connected to the upper side of the protective box 16. The protective box 16 and the inverted V-shaped plate 17 can work together to provide rain protection and prevent rainwater from eroding the bolts used to fix the mounting base 1.

[0028] A circular plate 18 is fixedly connected to the other side of each of the two telescopic rods 15, and a second connecting spring 19 is fixedly connected between each of the two circular plates 18 and the mounting base 1.

[0029] The upper side of the mounting base 1 is rotatably connected to two symmetrically distributed rotating plates 21, and one side of each rotating plate 21 is connected to a positioning seat 22 for limiting the high voltage disconnect switch body 2.

[0030] Each of the two round bases 3 has an embedding groove 20 on one side. The embedding groove 20 is adapted to the positioning block 7. One side of the positioning block 7 is engaged with one side of the round base 3 through the embedding groove 20.

[0031] One side of the L-shaped clamp 12 passes through the round base 3 and extends into the interior of the round base 3. One end of each of the two base plates 11 is threaded with a bolt 13 for fixing the L-shaped clamp 12. The bolt 13 can be used to press and fix the L-shaped clamp 12 to ensure the stability of the high-voltage disconnect switch when the two L-shaped clamps 12 are fixed. The structure of the high-voltage disconnect switch body 2 is made of ceramic material, so the high-voltage disconnect switch has the ability to resist low temperature and extends the service life of the high-voltage disconnect switch equipment outdoors.

[0032] The working principle of the outdoor low-temperature resistant high-voltage disconnector provided by this utility model is as follows:

[0033] By placing the two high-voltage disconnect switch bodies 2 into the mounting base 1, the round seats 3 at the two high-voltage disconnect switch bodies 2 can press the two positioning blocks 7, allowing the two displacement slide plates 5 equipped with the first connecting spring 6 to be compressed. In this way, the two elastic positioning blocks 7 can be engaged in the two round seats 3 to secure the high-voltage disconnect switch. Then, the four limit screws 9 are rotated in sequence to engage in the slots 10 of the two round seats 3. Subsequently, the two L-shaped locking plates 12 are pushed so that they can engage in the interior of the round seats 3, so that the two round seats 3 can be synchronously engaged and locked around their perimeter. This engagement method allows for convenient installation or disassembly of the high-voltage disconnect switch for maintenance work, improving the maintenance efficiency of the high-voltage disconnect switch equipment.

[0034] By first moving the two telescopic rods 15, which are equipped with the second connecting spring 19, upward, the elastic protective box 16 and the inverted V-shaped plate 17 can be moved to a higher position. Then, the bolts for fixing the mounting base 1 are inserted into the mounting groove 14 of the mounting base 1, so that the mounting base 1 can be fixed in the installation position using the bolts and the mounting groove 14, thereby fixing the high-voltage disconnecting switchgear at the place of use. Then, the elastic protective box 16 and the inverted V-shaped plate 17 are reset and placed above the mounting groove 14 to provide rain protection and prevent rainwater from corroding the bolts, ensuring the reliability and safety of fixing the high-voltage disconnecting switchgear. Next, the two rotating plates 21 are rotated respectively, so that the positioning seats 22 distributed in the array on the two rotating plates 21 are fitted and attached to one side of the high-voltage disconnecting switch to further limit and fix the high-voltage disconnecting switch, ensuring the stability of the outdoor low-temperature resistant high-voltage disconnecting switchgear.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
