Description

Technical Field

[0001] The present invention relates to the technical field of capacitors, and particularly to a compensation capacitor with an explosion-proof function. Background Art

[0002] A capacitor is a static charge storage substance that can store charge and electrical energy. Capacitance or electrical capacitance is a physical quantity representing the ability of a capacitor to hold charge. A capacitor, usually simply referred to as having the ability to hold charge as capacitance, is a device for holding charge. Capacitors are one of the most widely used electronic components in electronic devices and are widely used in aspects such as DC blocking and AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, control, etc. A capacitor is formed between any two conductors (including wires) that are insulated from each other and are very close to each other.

[0003] Existing capacitors are directly connected and used. During long-term use, the capacitors may age, resulting in air pockets, causing excessive internal pressure. When the pressure reaches a certain level, it will cause an explosion, posing a certain danger. When a capacitor explodes, it will damage the surrounding equipment, increasing the maintenance cost. At the same time, when the capacitor is vibrated, there is no buffer space inside, causing the capacitor to be squeezed and damaged, reducing its service life. Summary of the Invention

The capacitor body is movably installed inside the protective shell. A stabilizing mechanism is provided inside the protective shell. A top cover is installed on the top of the protective shell. A heat dissipation mechanism is provided on the top cover, and a plurality of third openings are evenly opened on the top of the top cover.

[0006] Preferably, a movable plate is slidably installed at the bottom of the protective shell. A plurality of first spring telescopic rods are evenly installed at the bottom of the movable plate. The installation 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. The bottom of the capacitor body is connected to the top of the movable plate.

[0007] Preferably, the stabilizing mechanism includes an auxiliary plate and a telescopic plate. Auxiliary plates are movably installed on both inner walls of the protective shell. A second slot is opened on the side of the auxiliary plate close to the capacitor body. A telescopic plate is slidably installed inside the second slot. A roller is rotatably installed on the side of the telescopic plate close to the capacitor body, and the roller abuts against the side wall of the capacitor body.

[0008] Preferably, lifting sliding grooves are formed on the inner walls of both sides of the protective case. A lifting electric slider is installed on one side of the auxiliary plate close to the lifting sliding groove, and the lifting electric slider is slidably installed inside the lifting sliding groove.

[0009] Preferably, stable sliding grooves are formed on the inner walls of both ends of the second slot. A stable slider is slidably installed inside the stable sliding groove, and one side of the stable slider close to the telescopic plate is connected to the telescopic plate.

[0010] Preferably, a pressure sensor is installed at the bottom end of the inner wall of the second slot. A second spring telescopic rod is installed on one side of the telescopic plate close to the pressure sensor, and one end of the second spring telescopic rod close to the pressure sensor abuts against the pressure sensor.

[0011] Preferably, the heat dissipation mechanism includes a fan, a first opening and a second opening. A plurality of first openings are evenly formed on the top of the top cover, a plurality of second openings are evenly formed on the top of the top cover, and a fan is installed at the bottom of the top cover.

[0012] Preferably, a lifting plate is movably installed on the top of the top cover. An auxiliary rod is installed at the bottom of the lifting plate close to the first opening, and the auxiliary rod is inserted into the first opening. A contact column is installed at the bottom of the lifting plate close to the second opening, and the contact column can be inserted into the second opening.

[0013] Preferably, an electric lifting rod is installed at the bottom of the lifting plate, the installation end of the electric lifting rod faces downward, and the installation end of the electric lifting rod is connected to the top of the top cover.

[0014] Preferably, a first slot is formed on the auxiliary rod. A nozzle is embedded at the top end of the inner wall of the first slot, and a temperature sensor is installed at the bottom end of the inner wall of the first slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, by providing a protective case and a movable plate, when the capacitor body explodes, a relatively closed space is formed inside the protective case. When the capacitor body explodes, the explosion shock wave can be absorbed by the protective case, preventing the capacitor body from damaging surrounding devices during the explosion and increasing the use safety of the device. During the use of the capacitor body, when the device vibrates, when the vibration value is transmitted to the movable plate, the vibration value can be absorbed by the first spring telescopic rod and then transmitted to the capacitor body. By this operation method, vibration damping of the capacitor body can be achieved, thereby reducing the influence of the vibration of the device body on the capacitor body and increasing the functional use stability of the capacitor body.

[0016] In the present invention, by providing an auxiliary plate and a telescopic plate, when the movable plate vibrates the capacitor body, when the movable plate and the capacitor body fluctuate up and down due to vibration, the contact of the roller with the capacitor body can increase the fluctuation stability of the capacitor body. Since the telescopic plate is also connected to the second spring telescopic rod, the way the roller contacts the capacitor body can not only increase the stability of the capacitor body, but also enhance the vibration damping effect of the device on the capacitor body; After the capacitor body is used for a period of time, the auxiliary plate performs corresponding lifting inside the protective shell. During the process of the roller rolling while contacting the capacitor body, if the capacitor body bulges, the bulging part will squeeze the roller, thereby causing the telescopic plate to be squeezed. 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, and the pressure sensor transmits the measured pressure value to the background control system for comparison. When the change in the pressure value exceeds the preset change value range, it is immediately fed back to the background control system and the staff is notified for maintenance. Through this operation method, the flatness of the outer side of the capacitor body can be detected, preventing the capacitor body from continuing to work when the outer side bulges, causing an explosion of the capacitor body, reducing the risk of explosion of the capacitor body, and increasing the safety of use of the device; When the capacitor body explodes, the outer shell of the capacitor body will expand rapidly, and the capacitor body will quickly squeeze the roller, so that the pressure value measured by the pressure sensor is rapidly increased. At this time, the background control system determines that the capacitor body is about to explode, so that the device takes corresponding explosion-proof measures in advance, increasing the convenience of use of the device.

[0017] In the present invention, by providing an auxiliary rod, a contact column and a fan, when the contact column does not contact the second opening, the second opening is opened, and the auxiliary rod moves to the use state where the first slot is connected to the first opening. At this time, the fan starts, and the fan discharges the air inside the protective shell through the second opening and the first opening to the outside. Through this operation method, the temperature inside the protective shell can be reduced, thereby reducing the temperature of the capacitor body and increasing the safety of use of the capacitor body; When the system determines that the capacitor body is about to explode, the contact column is inserted into the second opening, and the top plane of the first slot moves below the top plane of the first opening. At this time, a relatively closed space is formed inside the protective shell. When the capacitor body explodes, the protective shell absorbs the explosion shock wave, preventing the capacitor body from damaging surrounding equipment during the explosion, and increasing the safety of use of the device.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figure 1-8 , a compensation capacitor with explosion-proof function, including a protective case 1 and a capacitor body 14. The capacitor body 14 is movably installed inside the protective case 1. A stabilizing mechanism is provided inside the protective case 1. A top cover 2 is installed on the top of the protective case 1. A heat dissipation mechanism is provided on the top cover 2. A plurality of third openings 9 are evenly opened on the top of the top cover 2. The stabilizing mechanism can increase the damping effect of the device on the capacitor body 14, and the heat dissipation mechanism can dissipate heat from the capacitor body 14, increasing the functional stability of the capacitor body 14.

[0022] As a technical optimization solution of the present invention, a movable plate 15 is slidably installed at the bottom of the protective case 1. A plurality of first spring telescopic rods 16 are evenly installed at the bottom of the movable plate 15. The installation ends of the first spring telescopic rods 16 are connected to the inner wall bottom end of the protective case 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 the use of the capacitor body 14, when the device vibrates, the vibration will be transmitted to the protective case 1 at this time. When the protective case 1 transmits the vibration value to the capacitor body 14 through the movable plate 15, the vibration value can be absorbed by the first spring telescopic rods 16 and then transmitted to the capacitor body 14. Through this operation method, vibration reduction of the capacitor body 14 can be realized, thereby reducing the influence of the vibration of the device body on the capacitor body 14 and increasing the functional use stability of the capacitor body 14.

[0023] As a technical optimization solution of the present invention, the stabilizing mechanism includes an auxiliary plate 17 and a telescopic plate 20. The auxiliary plates 17 are movably installed on the inner walls on both sides of the protective case 1. A second slot 22 is opened on the side of the auxiliary plate 17 close to the capacitor body 14. A telescopic plate 20 is slidably installed inside the second slot 22. A roller 21 is rotatably installed on the side of the telescopic plate 20 close to the capacitor body 14. The roller 21 abuts against the side wall of the capacitor body 14. When the movable plate 15 reduces the vibration of 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 fluctuate up and down due to vibration, the abutment of the roller 21 against the capacitor body 14 can increase the fluctuation stability of the capacitor body 14.

[0024] As a technical optimization solution of the present invention, lifting chutes 18 are opened on the inner walls on both sides of the protective case 1. A lifting electric slider 19 is installed on the side of the auxiliary plate 17 close to the lifting chute 18. The lifting electric slider 19 is slidably installed inside the lifting chute 18. By the sliding of the lifting electric slider 19 in the lifting chute 18, the auxiliary plate 17 can be lifted according to different usage requirements, increasing the use convenience of the device.

[0025] As a technical optimization solution of the present invention, stabilizing chutes 24 are opened on the inner walls at both ends of the second slot 22. A stabilizing slider 25 is slidably installed inside the stabilizing chute 24. The side of the stabilizing slider 25 close to the telescopic plate 20 is connected to the telescopic plate 20. By the sliding of the stabilizing slider 25 in the stabilizing chute 24, the sliding of the telescopic plate 20 in the second slot 22 is made more stable.

[0026] As a technical optimization solution of the present invention, a pressure sensor 23 is installed at the bottom end of the inner wall of the second slot 22. A second spring telescopic rod 26 is installed on one side of the telescopic plate 20 close to the pressure sensor 23. One end of the second spring telescopic rod 26 close to the pressure sensor 23 is in contact with the pressure sensor 23. During the process of the roller 21 rolling while abutting against the capacitor body 14, if the capacitor body 14 bulges, the bulging part will squeeze the roller 21, so that the telescopic plate 20 is squeezed. 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 change in the pressure value exceeds the preset change value range, it is immediately fed back to the background control system and the staff is notified for 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 continuously working when the outer side bulges, causing an explosion of the capacitor body 14, reducing the risk of explosion of the capacitor body 14, and increasing the safety of use of the device.

[0027] As a technical optimization solution of the present invention, the heat dissipation mechanism includes a fan 13, a first opening 5 and a second opening 7. A plurality of first openings 5 are evenly opened at the top of the top cover 2, and a plurality of second openings 7 are evenly opened at the top of the top cover 2. A fan 13 is installed at the bottom of the top cover 2. When the fan 13 is started, at this time, the fan 13 discharges the air inside the protective case 1 to the outside through the second opening 7 and the first opening 5. Through this operation method, the temperature inside the protective case 1 can be reduced, thereby completing the cooling of the capacitor body 14 and increasing the safety of use of the capacitor body 14.

[0028] As a technical optimization solution of the present invention, a lifting plate 3 is movably installed at the top of the top cover 2. An auxiliary rod 6 is installed at the bottom of the lifting plate 3 close to the first opening 5. The auxiliary rod 6 is inserted into the first opening 5. A contact column 8 is installed at the bottom of the lifting plate 3 close to the second opening 7. The contact column 8 can be inserted into the second opening 7. The auxiliary rod 6 is inserted into the first opening 5, and the contact column 8 is inserted into the second opening 7, so that a relatively closed space is formed inside the protective case 1. When the capacitor body 14 explodes, by absorbing the explosion shock wave by the protective case 1, it can prevent the capacitor body 14 from damaging the surrounding equipment during the explosion, increasing the safety of use of the device.

[0029] As a technical optimization solution of the present invention, an electric lifting rod 4 is installed at the bottom of the lifting plate 3. The installation end of the electric lifting rod 4 faces downward, and the installation end of the electric lifting rod 4 is connected to the top of the top cover 2. The electric lifting rod 4 can drive the lifting plate 3 to lift according to different usage requirements.

[0030] As a technical optimization solution of the present invention, a first slotted groove 10 is formed on the auxiliary rod 6. The top end of the inner wall of the first slotted groove 10 is embedded with a nozzle 11, and the bottom end of the inner wall of the first slotted groove 10 is provided with a temperature sensor 12. When the capacitor body 14 catches fire, at this time the auxiliary rod 6 moves to the preset use position. Subsequently, the electric pump connected to the nozzle 11 is started. The electric pump extracts the dry powder fire extinguishing agent from the dry powder fire extinguishing agent storage tank and sprays it through the nozzle 11, which can extinguish the fire inside the protective shell 1, reduce the damage degree of the fire to the capacitor body 14, and increase the use safety of the device. The temperature sensor 12 can detect the temperature inside the protective shell 1, which is convenient for the internal cooling and fire detection of the device. Through the use positions at different heights of the auxiliary rod 6, the first slotted groove 10 can have both the heat dissipation and plugging use effects on the inside of the protective shell 1.

[0031] When the present invention is in use, the electrical equipment used in the device is all powered by connecting to an external power source through wires. The device controls the electrical equipment in the device by setting a control system. The temperature sensor 12 and the pressure sensor 23 used in the device are both existing mature technologies, so no more elaboration will be made on them. The side of the nozzle 11 away from the temperature sensor 12 is connected to a preset dry powder fire extinguishing agent storage tank and an electric pump outside the device by means of a conduit passing through the lifting plate 3 and the auxiliary rod 6. The connection method of the nozzle 11 with the conduit, the dry powder fire extinguishing agent storage tank and the electric pump is an existing mature technology, so no more elaboration will be made on it. The capacitor body 14 is connected with a wire. One end of the wire away from the capacitor body 14 passes through the third opening 9 and extends to the outside of the protective shell 1, and one end of the wire away from the capacitor body 14 is connected to the required equipment.

[0032] During the use of the capacitor body 14, when the equipment vibrates, at this time the vibration will be 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, since the capacitor body 14 is installed on the top of the movable plate 15 and the bottom of the movable plate 15 is provided with a first spring telescopic rod 16, when the vibration value is transmitted to the movable plate 15, the first spring telescopic rod 16 can absorb the vibration value, and then transmit it to the capacitor body 14. Through this operation method, the vibration reduction of the capacitor body 14 can be realized, thereby reducing the influence of the vibration of the equipment body on the capacitor body 14 and increasing the functional use stability of the capacitor body 14.

[0033] When the movable plate 15 vibrates 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 fluctuate up and down due to vibration, 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 vibration reduction effect of the device on the capacitor body 14.

[0034] After the capacitor body 14 has been used for a period of time, at this time, by sliding the lifting electric slider 19 in the lifting chute 18, the auxiliary plate 17 is lifted correspondingly inside the protective shell 1. Since the roller 21 abuts against the outside of the capacitor body 14, during the lifting process of the auxiliary plate 17, when the roller 21 rolls while abutting against the capacitor body 14, if the capacitor body 14 bulges, the bulging part will squeeze the roller 21, thereby causing the telescopic plate 20 to be squeezed. 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, and the pressure sensor 23 transmits the measured pressure value to the background control system for comparison. When the change in the pressure value exceeds the preset change value range, it is immediately fed back to the background control system and the staff is notified for maintenance. Through this operation method, the flatness of the outside of the capacitor body 14 can be detected, preventing the capacitor body 14 from continuing to work when the outside bulges, causing an explosion of the capacitor body 14, reducing the risk of explosion of the capacitor body 14, and increasing the safety of use of the device.

[0035] During the use of the capacitor body 14, the temperature inside the protective shell 1 is detected by the temperature sensor 12. When the temperature measured by the temperature sensor 12 exceeds the preset temperature value, the lifting plate 3 moves to the Figure 1 shown state of use, and the fan 13 starts. At this time, the fan 13 discharges the air inside the protective shell 1 outwards through the second opening 7 and the first opening 5. Through this operation method, the temperature inside the protective shell 1 can be reduced, thereby reducing the temperature of the capacitor body 14 and increasing the safety of use of the capacitor body 14.

[0036] When the capacitor body 14 explodes, the outer shell of the capacitor body 14 will expand rapidly, and the capacitor body 14 will quickly squeeze the roller 21, so that the pressure value measured by the pressure sensor 23 will increase rapidly. At this time, the background control system determines that the capacitor body 14 is about to explode, and the electric lifting rod 4 contracts, causing the lifting plate 3 to move downward until the abutting column 8 is inserted into the second opening 7, and the top plane of the first slot 10 moves below the top plane of the first opening 5. At this time, a relatively closed space is formed inside the protective shell 1. When the capacitor body 14 explodes, by absorbing the explosion shock wave by the protective shell 1, it can prevent the capacitor body 14 from damaging the surrounding equipment during the explosion, increasing the use safety of the device.

[0037] When the device is in use and after the capacitor body 14 explodes, if the temperature value measured by the temperature sensor 12 exceeds the preset temperature value, it means that the capacitor body 14 inside the protective shell 1 is on fire at this time. The auxiliary rod 6 moves downward until the nozzle 11 is located below the bottom of the top cover 2. Subsequently, the electric pump connected to the nozzle 11 starts. The electric pump pumps out the dry powder fire extinguishing agent in the dry powder fire extinguishing agent storage tank and sprays it through the nozzle 11, which can extinguish the fire inside the protective shell 1, reduce the damage degree of the fire to the capacitor body 14, and increase the use safety of the device.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
