[0002] A low-voltage reactive power compensation device is a device used to improve the power factor of an electric power system. It reduces reactive current in the power grid by injecting or absorbing reactive power into the power system, thereby improving the power factor of the power grid, reducing line losses, and extending the service life of the equipment.

[0003] Low-voltage reactive compensation devices are generally placed in a protective shell for protection, usually a cabinet-shaped protective shell, also known as a compensation cabinet, which can prevent dust, oil and other external environment from damaging the internal electrical components, thereby extending the service life of the device. At the same time, the whole is usually made of metal material, with good structural strength and rigidity, and can withstand certain mechanical shocks and pressures.

[0004] However, after some low-voltage reactive compensation devices enter the protective shell, the external lines are directly passed through the protective shell and connected to the device. The excess length of the lines cannot be gathered, which easily leads to too many lines being exposed to the outside or scattered inside the protective shell, which not only affects the appearance and neatness, but also easily brings safety risks. At the same time, the space inside the protective shell of some low-voltage reactive compensation devices is fixed and cannot be adjusted or changed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

A switch assembly is provided at the front end of the shell 1, and the switch assembly includes a rotating door 2 and a rotating door 3. The rotating door 2 is rotatably connected to the left side of the front end of the shell 1, and the rotating door 2 is rotatably connected to the right side of the front end of the shell 1. The rotating door 23 is against the front ends of multiple slide bars 10. The right side of the shell 1 is provided with uniformly distributed threading holes 4, and the left and right sides of the partition 5 are provided with uniformly distributed threading holes 2 18. The tops of the multiple blocks 14 are provided with grooves 15, and the left and right sides of the inner wall of the groove 15 are fixedly connected with spring pieces 16. The middle of the rotating block 7 is fixedly connected with a turntable 17.

[0033] The rotating door 2 3 is turned to open, and the low-voltage reactive power compensation device or other equipment is placed into the left side of the housing 1. After the rotating door 2 3 is opened, the spring 12 will rebound to the limit ring 11 and push the slide bar 10 forward to leave the engaged card slot 13, and then the external line is extended into the right side of the housing 1 through one of the threading holes 4, and the line end is placed into one of the grooves 15 and clamped by two spring pieces 16. The rotating disk 17 is held to drive the rotating block 7 to rotate. When the rotating block 7 rotates, the line is continuously pulled into the housing 1 and wound around the rotating shaft 8 to prevent too much from being left outside or scattered in the housing 1. When winding multiple lines, multiple blocks 14 are used to separate the winding to avoid mixing of multiple lines. After winding, the line head is taken out from the groove 15. During the process, the spring pieces 16 on both sides will be squeezed. After taking them out, the spring pieces 16 on both sides are reset again by their own elasticity. The line head is passed through one of the threading holes 18 into the left side of the shell 1. The low-voltage reactive power compensation device or other equipment placed in the shell 1 can be connected. The rotating door 23 is rotated to close and the sliding rod 10 is pushed backward until it is engaged in one of the slots 13. At the same time, the limit ring 11 will squeeze the spring 12 to prevent the rotating block 7 from rotating accidentally.

The position of the placement plate 19 on the left side of the shell 1 can be changed according to the size of the low-voltage reactive power compensation device. The two handles 24 are then released to allow the two springs 25 to rebound and pop out the two locking blocks 23 to snap into two of the locking grooves 21. After the change, the low-voltage reactive power compensation device is placed in the shell 1. The positions of the remaining placement plates 19 can also be adjusted and other equipment can be placed. The multiple threading holes 18 and the multiple locking grooves 21 are staggered and do not interfere with each other. The multiple placement plates 19 can be adjusted first and then the first one can be extended through the threading hole 18 and connected to the equipment. After completion, the revolving door 2 is closed by rotation.

[0036] Reference Figure 1 and Figure 2 A ventilation plate 26 is fixedly connected to the middle upper side of the inner wall of the shell 1, a partition 5 is fixedly connected to the middle right side of the bottom of the ventilation plate 26, a fan 28 is fixedly connected to the top of the inner wall of the shell 1, and a dustproof net 29 is fixedly connected to the bottom of the front end of the rotating door 1 2 and the rotating door 2 3, a dustproof net 1 27 is fixedly connected to the front end of the top of the inner wall of the shell 1, and the dustproof net 1 27 is fixedly connected to the front end of the top of the ventilation plate 26, and an observation window 30 is provided on the top of the front end of the rotating door 1 2 and the rotating door 2 3.

[0037] Start multiple fans 28 and suck external air into the shell 1 through the dustproof net 1 27 to form wind. The wind passes through the ventilation plate 26 to blow away the heat from the equipment and lines in the shell 1, and is finally discharged through the two dustproof nets 29. The dustproof net 1 27 and the two dustproof nets 29 prevent external dust from entering the shell 1. The ventilation plate 26 limits the placement plate 19 to prevent the placement plate 19 from rising excessively and hitting the fan 28. The conditions of the equipment and lines inside the shell 1 can be observed through the two observation windows 30.

[0038] Working principle: when in use, open the revolving door 2, select the two handles 24 on one of the placement plates 19 and hold them to slide close to each other, so that the two engaging blocks 23 enter the placement plate 19, and then adjust the position of the placement plate 19 by sliding the slider 22 in the slide groove 20 according to the size of the low-voltage reactive power compensation device. After adjustment, release the two handles 24 to make the springs 25 on both sides rebound to push out the engaging blocks 23 on both sides and engage in the engaging grooves 21 on both sides at the current position. After the change, put the low-voltage reactive power compensation device in, and then adjust the position of the remaining placement plates 19 in the housing 1 and place other equipment, open the revolving door 3, at this time, the spring 12 rebounds to the limit ring 11 and pushes the slide bar 10 forward to leave the currently engaged slot 1 3.

After winding, take the line end out of the groove 15 and pass it through one of the threading holes 2 18 to connect with the device, finally rotate and close the rotating door 1 2 and the rotating door 2 3 in turn. After the rotating door 2 3 is closed, the slide bar 10 will be lowered and pushed backward until it is engaged in the slot 13 at the current position, and the rotating shaft 8 will be fixed to prevent self-rotation. At the same time, the limit ring 11 will also squeeze the spring 12 backward and wait for it to rebound again.
