Description

Technical Field

[0001] The invention relates to the technical field of capacitors, and in particular to an intelligent capacitor capable of monitoring temperature. Background Art

[0002] Intelligent capacitors are composed of high-quality capacitors, reactors, intelligent measurement and control modules, switching modules, line protection modules, and human-machine interface modules. This modular design not only makes the equipment compact, but also facilitates on-site wiring and maintenance. Intelligent capacitors are widely used in factory power distribution systems, residential power distribution systems, municipal commercial buildings, traffic tunnel power distribution systems, as well as box transformers, complete sets of cabinets, outdoor distribution boxes and other fields, providing an effective solution for improving the power factor and increasing the efficiency of the power grid.

[0003] Existing smart capacitors are usually equipped with heat dissipation windows on their shells to ensure that they can maintain a stable temperature during operation, thereby extending their service life and ensuring safe operation. However, when the ambient temperature is high, the natural heat dissipation through ventilation through the heat dissipation windows alone may not be able to meet the heat dissipation requirements. In addition, the shell of the smart capacitor is usually fixed with screws. When the internal components of the smart capacitor need to be maintained and repaired later, disassembly requires the use of tools, which is troublesome and reduces the efficiency of maintenance. Summary of the invention

[0016] Beneficial Effects

[0017] Compared with the prior art, the present invention provides an intelligent capacitor capable of monitoring temperature, which has the following beneficial effects:

[0018] 1. The intelligent capacitor capable of monitoring temperature sets a cooling fan on the cover plate and monitors the temperature inside the capacitor shell in real time through a temperature sensor. When the temperature exceeds the set value, the temperature sensor transmits a signal to the controller to automatically turn on the cooling fan, allowing air to enter the interior through the heat dissipation holes and then take the heat out, thereby speeding up the air flow and improving the heat dissipation effect. When the temperature drops, the controller will turn off the cooling fan.

[0019] 2. The temperature-monitoring intelligent capacitor has a limit assembly set on the side wall of the capacitor housing. When the internal components of the capacitor housing need to be maintained, the rotating rod is rotated to move out of the slot, so that the compressed telescopic spring can be restored and the plug-in rod can be pulled out of the slot, so that the cover can be quickly unlocked and removed, thereby improving the efficiency of maintenance.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 6 , including a capacitor housing 1, a side wall of the capacitor housing 1 is provided with an inspection port 4, a cover plate 5 is provided inside the inspection port 4, a heat dissipation port 6 is provided in the middle of the cover plate 5, a heat dissipation fan 7 is provided inside the heat dissipation port 6, a temperature sensor 22 and a controller 23 are provided on the back of the cover plate 5, and a limiting component for limiting and fixing the cover plate 5 is provided on the side wall of the capacitor housing 1.

[0029] Among them, the temperature sensor 22 and the cooling fan 7 are both electrically connected to the controller 23. When the temperature sensor 22 detects that the temperature inside the capacitor housing 1 exceeds the set value, the temperature sensor 22 will transmit a signal to the controller 23 to automatically turn on the cooling fan 7, so that air enters the interior through the cooling holes 8 and then takes the heat out, which can speed up the air flow rate, thereby improving the heat dissipation effect. When the temperature drops, the controller 23 will turn off the cooling fan 7, so that the cooling fan 7 is automatically turned on when the temperature is high, which is more energy-saving.

[0030] The limit assembly includes two shells 10, which are installed on the side walls of the capacitor shell 1 and located on both sides of the inspection port 4. The interior of the shell 10 is slidably connected with a moving block 12. The front surface of the moving block 12 is fixedly connected with a fixing rod 13. The end of the fixing rod 13 away from the moving block 12 passes through the shell 10 and extends to the outside. The outside of the fixing rod 13 is provided with a telescopic spring 17 installed between the moving block 12 and the inner wall of the shell 10. The upper and lower sides of the moving block 12 are both hinged with connecting rods 14, which connect A slider 15 is hinged on the side of the rod 14 away from the moving block 12, and a plug-in rod 16 is fixedly connected to the side of the slider 15 away from the connecting rod 14. One end of the plug-in rod 16 away from the slider 15 passes through the shell 10 and extends to the outside. Two embedded blocks 11 are provided on the left and right sides of the cover 5, and slots are provided on the opposite sides of the upper and lower embedded blocks 11. One end of the plug-in rod 16 is plugged into the inside of the slot. The surface of the capacitor shell 1 is provided with embedded grooves 24 located on both sides of the inspection port 4, and the embedded blocks 11 are adapted to the embedded grooves 24.

[0031] It should be noted that when installing the cover 5, the cover 5 can be limited by inserting the embedding block 11 into the embedding groove 24, so that the cover 5 is embedded in the inspection port 4, and the inspection port 4 can be sealed to prevent impurities in the environment from easily entering the capacitor housing 1.

[0032] See also Figure 4 , Figure 5 In this embodiment, the fixed rod 13 is rotatably connected to a rotating rod 18 on one side away from the shell 10, and blocks 19 are provided on the edges of the left and right sides of the rotating rod 18. The front surface of the shell 10 is provided with two limit blocks 20, and a slot 21 is provided on the opposite side of the two limit blocks 20, and the block 19 is adapted to the slot 21.

[0033] By rotatable rotating rod 18, when plug-in rod 16 is moved out from embedded block 11, the spring is in normal state. If embedded block 11 needs to be locked, first press rotating rod 18 to stretch telescopic spring 17, and push moving block 12 to one side of capacitor housing 1, then connect rod 14 can be pushed to push plug-in rod 16 into the inside of slot, then rotate rotating rod 18 to lock into the inside of limit block 20, then rotating rod 18 can be limited, thus achieving locking effect.

[0034] When it is necessary to maintain the components inside the capacitor housing 1, the rotating rod 18 is rotated to move it out of the slot 21, so that the compressed telescopic spring 17 can be restored, driving the moving block 12 to move so that the connecting rod 14 pulls the slider 15 to move relatively, and the plug-in rod 16 can be pulled out of the slot, so that the cover plate 5 can be removed quickly and easily. The operation is convenient and no tools are needed, thereby improving the efficiency of maintenance.

[0035] See also Figure 1 In this embodiment, a plurality of heat dissipation holes 8 are provided inside the cover plate 5 , and two pull plates are provided on the front surface of the cover plate 5 .

[0036] In this embodiment, two handles 3 are provided on the top of the capacitor housing 1, a smart panel 2 is provided on the top of the capacitor housing 1, mounting plates 9 are provided on the left and right sides of the capacitor housing 1, and mounting holes are opened inside the mounting plates 9.

[0037] The handle 3 makes it easy to carry the capacitor for transfer, while the mounting plate 9 makes it convenient to fix the capacitor housing 1 at the position where it needs to be installed to avoid easy displacement.

[0038] In summary, the intelligent capacitor capable of monitoring temperature, by arranging a cooling fan 7 on the cover plate 5, enables the temperature sensor 22 to monitor the temperature inside the capacitor housing 1 in real time. When the temperature exceeds the set value of the temperature sensor 22, the temperature sensor 22 will transmit a signal to the controller 23 so that the controller 23 turns on the cooling fan 7. The cooling fan 7 cooperates with the cooling holes 8 to allow air to enter the interior through the cooling holes 8 and then take the heat out, thereby accelerating the speed of air flow, thereby improving the heat dissipation effect. When the temperature drops below the set value, the controller 23 will turn off the cooling fan 7, thereby meeting the heat dissipation requirements in different environments and being more energy-efficient. When it is necessary to maintain the components inside the capacitor housing 1, the rotating rod 18 is rotated to move out of the card slot 21, so that the compressed telescopic spring 17 can be restored, driving the moving block 12 to move so that the connecting rod 14 pulls the slider 15 to move relatively, and the plug-in rod 16 can be pulled out of the slot, thereby realizing quick unlocking and facilitating the removal of the cover plate 5. The operation is convenient and no tools are required, thereby improving the efficiency of maintenance.
