Description

Technical Field

[0001] This invention relates to the field of capacitor technology, and in particular to a compensation capacitor with explosion-proof function. Background Technology

[0002] A capacitor is a static charge storage medium capable of storing electrical charge and energy. Capacitance, or capacitance, is a physical quantity that represents a capacitor's ability to store charge. A capacitor, often simply referred to as its charge-storing capacity, is a device that stores electrical charge. Capacitors are among the most widely used electronic components in electronic devices, extensively applied in circuits for DC blocking and AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. A capacitor is formed between any two insulated conductors (including wires) that are very close together.

[0003] Existing capacitors are directly connected for use. Over time, this can lead to capacitor aging and the formation of air pockets, resulting in excessive internal pressure. If the pressure reaches a certain level, it can cause an explosion, posing a certain danger. When a capacitor explodes, it can damage surrounding equipment and increase maintenance costs. In addition, when the capacitor is subjected to vibration, it does not have enough internal space to buffer it, causing the capacitor to be crushed and damaged, reducing its service life. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a compensation capacitor with explosion-proof function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An explosion-proof compensation capacitor includes a protective shell and a capacitor body. The capacitor body is movably installed inside the protective shell. The protective shell has a stabilizing mechanism inside. A top cover is installed on the top of the protective shell. A heat dissipation mechanism is provided on the top cover. Multiple third openings are evenly provided on the top of the top cover.

[0007] Preferably, a movable plate is slidably mounted on the bottom of the protective shell, and a plurality of first spring telescopic rods are evenly mounted on the bottom of the movable plate. The mounting ends of the first spring telescopic rods are connected to the bottom end of the inner wall of the protective shell away from the movable plate, and the bottom of the capacitor body is connected to the top of the movable plate.

[0008] Preferably, the stabilizing mechanism includes an auxiliary plate and a telescopic plate. The auxiliary plate is movably installed on both inner walls of the protective shell. The auxiliary plate has a second slot on the side near the capacitor body. The telescopic plate is slidably installed inside the second slot. A roller is rotatably installed on the side of the telescopic plate near the capacitor body. The roller abuts against the side wall of the capacitor body.

[0009] Preferably, lifting grooves are provided on both inner walls of the protective shell, and a lifting electric slider is installed on the side of the auxiliary plate near the lifting groove, and the lifting electric slider is slidably installed inside the lifting groove.

[0010] Preferably, stabilizing grooves are provided on the inner walls of both ends of the second slot, and stabilizing sliders are slidably installed inside the stabilizing grooves. The side of the stabilizing slider closest to the telescopic plate is connected to the telescopic plate.

[0011] Preferably, a pressure sensor is installed at the bottom of the inner wall of the second slot, and a second spring telescopic rod is installed on the side of the telescopic plate near the pressure sensor, with the end of the second spring telescopic rod near the pressure sensor abutting against the pressure sensor.

[0012] Preferably, the heat dissipation mechanism includes a fan, a first opening and a second opening, a plurality of first openings are evenly provided on the top of the top cover, a plurality of second openings are evenly provided on the top of the top cover, and a fan is installed on the bottom of the top cover.

[0013] Preferably, a lifting plate is movably installed on the top of the top cover, and an auxiliary rod is installed at the bottom of the lifting plate near the first opening. The auxiliary rod is inserted into the inside of the first opening. An abutment post is installed at the bottom of the lifting plate near the second opening. The abutment post can be inserted into the inside of the second opening.

[0014] Preferably, an electric lifting rod is installed at the bottom of the lifting plate, with the mounting end of the electric lifting rod facing downwards and connected to the top of the top cover.

[0015] Preferably, the auxiliary rod has a first slot, a nozzle is embedded in the top of the inner wall of the first slot, and a temperature sensor is installed at the bottom of the inner wall of the first slot.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, by providing a protective shell and a movable plate, when the capacitor body explodes, the interior of the protective shell forms a relatively sealed space. When the capacitor body explodes, the protective shell absorbs the explosion shock wave, which can prevent the capacitor body from damaging surrounding equipment during the explosion, thus increasing the safety of the device.

[0018] When the equipment vibrates during use, the vibration value is transmitted to the movable plate. The first spring telescopic rod can absorb the vibration value before it is transmitted to the capacitor body. This operation method can reduce the vibration of the capacitor body, thereby reducing the impact of the equipment vibration on the capacitor body and increasing the functional stability of the capacitor body.

[0019] In this invention, by setting up an auxiliary plate and a telescopic plate, when the movable plate dampens the capacitor body, when the movable plate and the capacitor body are subjected to vibration and fluctuate up and down, the roller abuts against the capacitor body, which can increase the fluctuation stability of the capacitor body. Since the telescopic plate is also connected to a second spring telescopic rod, the way the roller abuts against the capacitor body can not only increase the stability of the capacitor body, but also enhance the damping effect of the device on the capacitor body.

[0020] After the capacitor body has been used for a period of time, the auxiliary plate moves up and down inside the protective shell. If the capacitor body bulges during the rolling process of the roller against the capacitor body, the bulge will squeeze the roller, thereby squeezing the telescopic plate. The telescopic plate slides towards the inside of the second slot and squeezes the second spring telescopic rod. The second spring telescopic rod squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system for comparison. When the pressure value changes beyond the preset range, it immediately feeds back to the background control system and notifies the staff to carry out maintenance. This operation method can detect the flatness of the outside of the capacitor body, prevent the capacitor body from continuing to work when the outside of the capacitor body bulges, which could cause the capacitor body to explode, reduce the risk of capacitor body explosion, and increase the safety of the device.

[0021] When the capacitor body explodes, the outer shell of the capacitor body will expand rapidly, and the capacitor body will quickly squeeze the roller, thereby causing the pressure value measured by the pressure sensor to rise rapidly. At this time, the background control system determines that the capacitor body is about to explode, so that the device can take corresponding explosion-proof measures in advance, increasing the ease of use of the device.

[0022] In this invention, an auxiliary rod, abutting post, and a fan are provided. The abutting post does not abut against the second opening, allowing the second opening to open. The auxiliary rod moves to the working state where the first slot and the first opening are connected. At this time, the fan starts and exhausts the air inside the protective shell out through the second opening and the first opening. This operation method can cool down the inside of the protective shell, thereby cooling down the capacitor body and increasing the safety of the capacitor body.

[0023] When the system determines that the capacitor body is about to explode, the abutment post is inserted into the interior of the second opening, and the top plane of the first slot moves to below the top plane of the first opening. At this time, a relatively sealed space is formed inside the protective shell. When the capacitor body explodes, the protective shell absorbs the explosion shock wave, which can prevent the capacitor body from damaging the surrounding equipment during the explosion, thus increasing the safety of the device.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figure 1-8 An explosion-proof compensation capacitor includes a protective shell 1 and a capacitor body 14. The capacitor body 14 is movably installed inside the protective shell 1. A stabilizing mechanism is provided inside the protective shell 1. A top cover 2 is installed on the top of the protective shell 1, and a heat dissipation mechanism is provided on the top cover 2. Multiple third openings 9 are evenly distributed on the top of the top cover 2. The stabilizing mechanism can increase the vibration reduction effect of the device on the capacitor body 14, and the heat dissipation mechanism can realize heat dissipation of the capacitor body 14, thereby increasing the functional stability of the capacitor body 14.

[0035] As a technical optimization of the present invention, a movable plate 15 is slidably installed on the bottom of the protective shell 1. Multiple first spring telescopic rods 16 are evenly installed on the bottom of the movable plate 15. The mounting ends of the first spring telescopic rods 16 are connected to the bottom end of the inner wall of the protective shell 1, away from the movable plate 15. The bottom of the capacitor body 14 is connected to the top of the movable plate 15. During use, when the equipment vibrates, the vibration is transmitted to the protective shell 1. When the protective shell 1 transmits the vibration value to the capacitor body 14 through the movable plate 15, the first spring telescopic rods 16 can absorb the vibration value before transmitting it to the capacitor body 14. This operation method can achieve vibration reduction of the capacitor body 14, thereby reducing the impact of equipment vibration on the capacitor body 14 and increasing the functional stability of the capacitor body 14.

[0036] As a technical optimization of the present invention, the stabilizing mechanism includes an auxiliary plate 17 and a telescopic plate 20. The auxiliary plate 17 is movably mounted on both inner walls of the protective shell 1. A second slot 22 is formed on the side of the auxiliary plate 17 near the capacitor body 14. The telescopic plate 20 is slidably mounted inside the second slot 22. A roller 21 is rotatably mounted on the side of the telescopic plate 20 near the capacitor body 14, and the roller 21 abuts against the side wall of the capacitor body 14. When the movable plate 15 dampens the capacitor body 14, the side wall of the capacitor body 14 abuts against the roller 21. Therefore, when the movable plate 15 and the capacitor body 14 are subjected to vibration and fluctuate up and down, the abutment of the capacitor body 14 by the roller 21 increases the fluctuation stability of the capacitor body 14.

[0037] As a technical optimization of the present invention, lifting grooves 18 are provided on both inner walls of the protective shell 1. A lifting electric slider 19 is installed on the side of the auxiliary plate 17 near the lifting groove 18, and the lifting electric slider 19 is slidably installed inside the lifting groove 18. By sliding the lifting electric slider 19 in the lifting groove 18, the auxiliary plate 17 can be raised and lowered according to different usage requirements, increasing the ease of use of the device.

[0038] As a technical optimization of the present invention, stabilizing grooves 24 are provided on the inner walls of both ends of the second slot 22. A stabilizing slider 25 is slidably installed inside the stabilizing groove 24, and the side of the stabilizing slider 25 near the telescopic plate 20 is connected to the telescopic plate 20. By sliding the stabilizing slider 25 in the stabilizing groove 24, the sliding of the telescopic plate 20 in the second slot 22 is made more stable.

[0039] As a technical optimization of the present invention, a pressure sensor 23 is installed at the bottom of the inner wall of the second slot 22. A second spring telescopic rod 26 is installed on the side of the telescopic plate 20 near the pressure sensor 23, and the end of the second spring telescopic rod 26 near the pressure sensor 23 abuts against the pressure sensor 23. During the rolling process of the roller 21 against the capacitor body 14, if the capacitor body 14 bulges, the bulge will squeeze the roller 21, thereby squeezing the telescopic plate 20. The telescopic plate 20 slides towards the inside of the second slot 22 and squeezes the second spring telescopic rod 26. The second spring telescopic rod 26 squeezes the pressure sensor 23. The pressure sensor 23 transmits the measured pressure value to the background control system for comparison. When the pressure value change exceeds the preset change range, it immediately feeds back to the background control system and notifies the staff to carry out maintenance. Through this operation method, the flatness of the outer side of the capacitor body 14 can be detected, preventing the capacitor body 14 from continuing to work when bulging occurs, which could cause the capacitor body 14 to explode, reducing the risk of the capacitor body 14 exploding and increasing the safety of the device.

[0040] As a technical optimization of the present invention, the heat dissipation mechanism includes a fan 13, a first opening 5, and a second opening 7. Multiple first openings 5 ​​and multiple second openings 7 are evenly distributed on the top of the top cover 2. The fan 13 is installed at the bottom of the top cover 2. When the fan 13 is activated, it exhausts the air inside the protective shell 1 through the second openings 7 and the first openings 5. This operation method can cool the inside of the protective shell 1, thereby cooling the capacitor body 14 and increasing the safety of the capacitor body 14.

[0041] As a technical optimization of the present invention, a lifting plate 3 is movably installed on the top of the top cover 2. An auxiliary rod 6 is installed at the bottom of the lifting plate 3 near the first opening 5, and the auxiliary rod 6 is inserted into the interior of the first opening 5. An abutment post 8 is installed at the bottom of the lifting plate 3 near the second opening 7, and the abutment post 8 can be inserted into the interior of the second opening 7. The insertion of the auxiliary rod 6 into the interior of the first opening 5 and the insertion of the abutment post 8 into the interior of the second opening 7 creates a relatively sealed space inside the protective shell 1. When the capacitor body 14 explodes, the absorption of the explosion shock wave by the protective shell 1 can prevent the capacitor body 14 from damaging surrounding equipment during the explosion, thus increasing the safety of the device.

[0042] As a technical optimization of the present invention, an electric lifting rod 4 is installed at the bottom of the lifting plate 3, with the mounting end of the electric lifting rod 4 facing downwards and connected to the top of the top cover 2. The electric lifting rod 4 can drive the lifting plate 3 to rise and fall according to different usage requirements.

[0043] As a technical optimization of the present invention, the auxiliary rod 6 has a first slot 10, a nozzle 11 is embedded in the top of the inner wall of the first slot 10, and a temperature sensor 12 is installed at the bottom of the inner wall of the first slot 10. When the capacitor body 14 catches fire, the auxiliary rod 6 moves to the preset use position, and then the electric pump connected to the nozzle 11 starts. The electric pump extracts the dry powder extinguishing agent from the dry powder extinguishing agent storage tank and sprays it out through the nozzle 11, which can extinguish the fire inside the protective shell 1, reduce the damage of the fire to the capacitor body 14, and increase the safety of the device. The temperature sensor 12 can detect the temperature inside the protective shell 1, which facilitates the cooling of the device and the detection of fire. By using the auxiliary rod 6 at different heights, the first slot 10 can have both heat dissipation and sealing effects inside the protective shell 1.

[0044] In use, all electrical devices in this device are powered by an external power source via wires. The device controls the electrical devices through a control system. The temperature sensor 12 and pressure sensor 23 used in this device are existing mature technologies, so they will not be described in detail here. The nozzle 11 used in this device is connected to a pre-installed dry powder extinguishing agent storage tank and electric pump outside the device via a conduit that passes through the lifting plate 3 and the auxiliary rod 6. The connection between the nozzle 11 and the conduit, the dry powder extinguishing agent storage tank and the electric pump is an existing mature technology, so it will not be described in detail here. The capacitor body 14 is connected to a wire. The end of the wire away from the capacitor body 14 extends through the third opening 9 to the outside of the protective shell 1, and the end of the wire away from the capacitor body 14 is connected to the required equipment.

[0045] When the capacitor body 14 vibrates during use, the vibration is transmitted to the protective shell 1. The protective shell 1 transmits the vibration value to the capacitor body 14 through the movable plate 15. Since the capacitor body 14 is mounted on the top of the movable plate 15 and the bottom of the movable plate 15 is equipped with a first spring telescopic rod 16, the vibration value transmitted to the movable plate 15 can be absorbed by the first spring telescopic rod 16 before being transmitted to the capacitor body 14. This operation method can reduce the vibration of the capacitor body 14, thereby reducing the impact of the equipment vibration on the capacitor body 14 and increasing the functional stability of the capacitor body 14.

[0046] When the movable plate 15 dampens the capacitor body 14, the side wall of the capacitor body 14 abuts against the roller 21. Therefore, when the movable plate 15 and the capacitor body 14 are subjected to vibration and fluctuate up and down, the abutment of the roller 21 against the capacitor body 14 can increase the fluctuation stability of the capacitor body 14. Since the telescopic plate 20 is also connected to the second spring telescopic rod 26, the way the roller 21 abuts against the capacitor body 14 can not only increase the stability of the capacitor body 14, but also enhance the damping effect of the device on the capacitor body 14.

[0047] After the capacitor body 14 has been used for a period of time, the auxiliary plate 17 is raised and lowered inside the protective shell 1 by the sliding of the lifting slider 19 in the lifting groove 18. Since the roller 21 abuts against the outside of the capacitor body 14, if the capacitor body 14 bulges during the lifting and lowering process of the auxiliary plate 17, the bulge will squeeze the roller 21, thereby squeezing the telescopic plate 20. The telescopic plate 20 slides towards the inside of the second slot 22 and squeezes the second spring telescopic rod 26. The second spring telescopic rod 26 squeezes the pressure sensor 23. The pressure sensor 23 transmits the measured pressure value to the background control system for comparison. When the pressure value changes beyond the preset change range, it immediately feeds back to the background control system and notifies the staff to carry out maintenance. This operation method can detect the flatness of the outside of the capacitor body 14, prevent the capacitor body 14 from continuing to work when the outside of the capacitor body 14 bulges, which could cause the capacitor body 14 to explode, reduce the risk of the capacitor body 14 exploding, and increase the safety of the device.

[0048] During use, the capacitor body 14 uses a temperature sensor 12 to detect the temperature inside the protective casing 1. When the temperature measured by the temperature sensor 12 exceeds a preset temperature value, the lifting plate 3 moves to the position indicated by the temperature sensor 12. Figure 1 As shown in the usage state, and with fan 13 activated, fan 13 exhausts the air inside the protective shell 1 through the second opening 7 and the first opening 5. This operation method can cool down the inside of the protective shell 1, thereby cooling down the capacitor body 14 and increasing the safety of the capacitor body 14.

[0049] When the capacitor body 14 explodes, its outer shell expands rapidly, squeezing the roller 21. This causes the pressure value measured by the pressure sensor 23 to rise rapidly. At this point, the control system determines that the capacitor body 14 is about to explode, and the electric lifting rod 4 retracts, causing the lifting plate 3 to move downward until the abutment post 8 is inserted into the second opening 7. The top plane of the first slot 10 moves to below the top plane of the first opening 5. At this point, a relatively sealed space is formed inside the protective shell 1. When the capacitor body 14 explodes, the protective shell 1 absorbs the shock wave of the explosion, preventing the capacitor body 14 from damaging surrounding equipment during the explosion and increasing the safety of the device.

[0050] If the temperature value measured by the temperature sensor 12 exceeds the preset temperature value during use or after the capacitor body 14 explodes, it indicates that the capacitor body 14 inside the protective shell 1 is on fire. The auxiliary rod 6 moves downward until the nozzle 11 is located below the bottom of the top cover 2. Then the electric pump connected to the nozzle 11 starts. The electric pump extracts the dry powder extinguishing agent from the dry powder extinguishing agent storage tank and sprays it out through the nozzle 11. This can extinguish the fire inside the protective shell 1, reduce the damage of the fire to the capacitor body 14, and increase the safety of the device.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
