Description

Technical Field

[0001] The present invention relates to the field of UPS power supply, and in particular to a UPS main bypass switching device and a control method thereof. Background Art

[0002] UPS, or uninterruptible power supply, is a constant voltage and frequency uninterruptible power supply that contains an energy storage device and has an inverter as its main component. It is mainly used to provide uninterruptible power supply to a single computer, computer network system or other power electronic equipment.

[0003] When the main power supply is in normal working condition, the bypass and backup power supplies are both in standby state. When the main power supply is in normal working condition for a long time, the bypass and backup power supplies are also idle for a long time. When the circuit is not in use for a long time, the aging and damage of the circuit are not known. At this time, if the main power supply is cut off and the circuit jumps to the bypass or backup power supply, the aging circuit will cause the circuit to be unable to withstand the load, thereby increasing the risk of the circuit during use, thereby affecting the safety of the circuit use. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a UPS main bypass switching device and a control method thereof.

[0005] In a first aspect, the present invention provides a UPS main bypass switching device, including a UPS body, wherein the UPS body includes four control switches for controlling the connection of various circuits, wherein the four control switches are respectively a first switch, a second switch, a third switch and a fourth switch, and further includes:

[0006] A first mounting plate is fixed inside the UPS body, a transverse partition is fixed on the side wall of the first mounting plate, the transverse partition divides the inside of the UPS body into a detection space and a communication space, and the control switches are all located in the communication space;

[0007] A second mounting plate, fixed inside the detection space;

[0008] a periodic detection component, mounted on the second mounting plate, for connecting the circuit connected to the control switch to detect the circuit;

[0009] A control unit, used for periodically starting the periodic detection component to detect the circuit connected to the control switch;

[0010] The four control switches are respectively a first switch, a second switch, a third switch and a fourth switch, the first switch, the second switch, the third switch and the fourth switch are respectively a normal mode switch, a bypass mode switch, a backup mode switch and a maintenance mode switch, the normal mode switch, the bypass mode switch, the backup mode switch and the maintenance mode switch correspond to four circuits, namely a normal mode circuit, a bypass mode circuit, a backup mode circuit and a maintenance mode circuit, respectively, and control the connectivity of the corresponding circuits when the four control switches are respectively closed;

[0011] The four control switches and the corresponding circuits are installed inside the communication space, and the circuits corresponding to the four control switches extend into the detection space, so that the periodic detection component can be connected to the four circuits to detect them;

[0012] When the UPS body is working, the control unit starts the periodic detection component at a fixed time. After the periodic detection component is started, the circuits connected to the four control switches are detected in turn, so that when the periodic detection component is connected to a certain circuit, the circuit can be connected to the circuit detector to detect the voltage and current during the use of the circuit and the temperature during the use of the circuit, so as to detect the aging state of the circuit. When it is detected that any circuit in the bypass mode circuit, the backup mode circuit and the maintenance mode circuit is aged or fails and affects the use of the circuit, a warning can be issued to the user, and the corresponding aged or failed circuit is marked so that the user can replace or repair the aged or failed circuit, which is beneficial to avoid the unused circuit being in an unused state for a long time, and the circuit gradually aging or damaged, so that the UPS body cannot bear the load due to the damage of the circuit when the main bypass is switched, thereby causing a safety hazard during the use of the UPS body, which is beneficial to improve the safety of the main bypass switching process of the UPS body.

[0013] Preferably, the periodic detection component comprises:

[0014] A rotating cylinder is rotatably mounted on the side wall of the second mounting plate, a circuit detector for detecting the circuit is installed inside the rotating cylinder, and connectors connected to the two poles of the circuit detector are symmetrically fixed on the side wall of the rotating cylinder;

[0015] Two vacant connectors are symmetrically fixed on the side wall of the second mounting plate with the rotating cylinder as the center;

[0016] Four groups of detection connectors, two of which form a group, are fixed on the side wall of the second mounting plate in a circular array with the rotating cylinder as the center, and each group of detection connectors is respectively connected to the circuits at both ends of the circuits connected to the four control switches;

[0017] A driving assembly, mounted on the side wall of the second mounting plate, for driving the rotating drum to rotate, so that after the rotating drum rotates, it is respectively connected to each group of the detection connectors through the connectors to detect each circuit;

[0018] A circuit breaker assembly, mounted on the side wall of the rotating drum, for disconnecting the circuit from the power source when the rotating drum is connected to the circuit through the connector;

[0019] The driving assembly can drive the rotating drum to rotate, and when the rotating drum rotates, the connecting head is driven to rotate. When the connecting head rotates to connect with the vacant connecting head, the circuit detector inside the rotating drum is in an vacant closed state. When the connecting head rotates to connect with the detection connecting head, the four groups of detection connecting heads correspond to four circuits, namely, a normal mode circuit, a bypass mode circuit, a backup mode circuit and a maintenance mode circuit.

[0020] For example, when the connector is rotated to align with the detection connector corresponding to the bypass mode switch (i.e., the bypass mode switch) corresponding to the second switch, the connector is connected to the detection connector, so that the circuit detector can be connected to the bypass mode circuit, thereby detecting the bypass mode circuit. At this time, the disconnection component disconnects the connection of the bypass mode circuit, so that the bypass mode circuit is connected to the circuit detector alone, so that the bypass mode circuit is disconnected from the power supply, which is conducive to avoiding interference of the bypass mode circuit power supply connection to the circuit detector during the process of detecting the bypass mode circuit;

[0021] The circuit tester is an instrument for testing the power supply voltage of the circuit, etc. It is a commonly used instrument in the prior art and will not be described in detail here;

[0022] When the driving assembly drives the rotating drum to rotate, the circuit tester sequentially tests the normal mode circuit, bypass mode circuit, backup mode circuit and maintenance mode circuit corresponding to the first switch, the second switch, the third switch and the fourth switch, thereby helping to avoid accidental damage to the circuit when the circuit is idle for a long time, resulting in safety hazards during the main bypass switching of the UPS body.

[0023] Preferably, the circuit breaker assembly comprises:

[0024] A plurality of fixing frames are arranged corresponding to the detection connectors and fixed on the side wall of the second mounting plate, and a second connecting piece is rotatably mounted inside the fixing frames;

[0025] A plurality of first connection pieces, arranged corresponding to the detection connection heads and fixed on the corresponding side walls of the detection connection heads, wherein the first connection pieces and the second connection pieces are in electrical connection after contact;

[0026] A plurality of push plates are arranged corresponding to the second connecting pieces and fixed to the tops of the corresponding second connecting pieces, and an elastic component for pushing the push plates to return to their original positions is installed between the push plates and the fixing frame;

[0027] A straight rod is fixed on the side wall of the rotating cylinder, and a push block is fixed on both ends of the straight rod. Before the connector is connected to the detection connector, the push block pushes the push plate to drive the second connecting piece to rotate and disconnect the electrical connection with the circuit;

[0028] The rotation of the rotating cylinder drives the straight rod to rotate, and the straight rod drives the push block to rotate;

[0029] For example, before the connector rotates to align and connect with the two detection connectors connected to the bypass mode circuit, the push block rotates to push the push plates corresponding to the two detection connectors, and after the push plate is pushed, the second connection piece is driven to rotate, so that the second connection piece rotates to be separated from the first connection piece, so that the second connection piece is separated from the first connection piece and the connection between the bypass mode circuit and the power supply is disconnected, and when the push block pushes the push plate to flip, the elastic component is compressed, and when the connector rotates to align and connect with the two detection connectors connected to the bypass mode circuit, the push block presses against the push plate, so as to maintain the state after the second connection piece is separated from the first connection piece, so as to maintain the circuit disconnected, which is conducive to disconnecting the connection between the bypass mode circuit and the power supply when the bypass mode circuit is detected, and detecting the bypass mode circuit alone;

[0030] In summary, during the process of testing a circuit, the circuit can be disconnected from the power supply so that the circuit is connected to the circuit tester alone, which is beneficial to improving the accuracy of testing the circuit.

[0031] Preferably, it also includes:

[0032] A plurality of first pressure sensors are arranged corresponding to the push plates one by one and fixed on the side walls of the corresponding push plates, and the first pressure sensors are pressurized when the push block pushes the push plates;

[0033] Four switch assemblies, arranged corresponding to the four control switches, for automatically closing or opening the four control switches;

[0034] The control unit is further used to control the switch assembly so that any one of the first switch and the second switch that is not connected to the detection connector circuit corresponding to the first pressure sensor under pressure remains in a closed state when any one of the first pressure sensors is under pressure;

[0035] When the pushing block pushes the pushing plate, the first pressure sensor is pressurized;

[0036] For example, when the push block pushes the push plate corresponding to the detection connector connected to the bypass mode circuit, the first pressure sensor installed on the push plate is pressurized. Since the first switch is connected to the normal mode circuit and the second switch is connected to the bypass mode circuit, the second switch corresponds to the bypass mode circuit, that is, it is connected to the bypass mode circuit. After the first pressure sensor is pressurized, the control unit controls the first switch to close according to the switching pressure information of the first pressure sensor being pressurized. After the first switch is closed, the second switch, the third switch and the fourth switch are controlled to open.

[0037] To sum up, when testing a circuit, the control unit can control the remaining circuits to be connected to maintain the normal operation of the device, which is beneficial to avoid the situation where the device cannot operate normally due to the circuit being disconnected for testing when a certain circuit is being tested, which is beneficial to maintain the normal operation of the setting through circuit switching.

[0038] Preferably, it also includes:

[0039] A temperature sensor, fixed to the top of the transverse partition, for detecting the internal temperature of the communicating space;

[0040] The control unit is further configured to control the switch assembly so that the four control switches perform circuit switching according to priorities when the temperature sensor detects that the temperature exceeds a preset value, and the priority order is the first switch, the second switch, the third switch, and the fourth switch in descending order;

[0041] The temperature sensor can detect the internal temperature of the connected space. The user inputs a preset temperature value through the user end of the control unit. When the temperature detected by the temperature sensor exceeds the preset temperature value, the control unit controls the circuit to switch so that the circuit in use can be disconnected when the temperature rises, and the remaining circuits are switched to connect at the same time, which is conducive to automatic switching when the circuit temperature is too high to cause safety hazards, thereby helping to avoid the situation where the circuit temperature is too high during long-term use and causes safety hazards, thereby helping to improve the safety of the UPS body when in use;

[0042] For example, when the first switch is in the closed state, the normal mode switch is in the connected working state. At this time, the temperature sensor detects the internal temperature of the connected space. When it is detected that the temperature exceeds the preset temperature value, the control unit controls the switch component to switch the first switch to the open state. At this time, according to the priority of the second switch, the third switch and the fourth switch, the control unit controls the switch component to switch the second switch to the closed state, so that the circuit switches to the bypass mode circuit. If the periodic detection component is detecting the bypass mode circuit corresponding to the second switch at this time, the control unit controls the switch component to switch the third switch to the closed state, so that the circuit switches to the backup mode circuit, which is beneficial to avoid the situation where the circuit temperature is too high during long-term use and causes safety hazards, thereby helping to improve the safety of the UPS body during use.

[0043] Preferably, it also includes:

[0044] Two second boxes are symmetrically fixed at two ends of the transverse partition, and the opposite ends of the two second boxes are provided with ventilation windows;

[0045] Four exhaust fans, two in a group, the two groups of exhaust fans are symmetrically fixed to the upper and lower ends of the two second boxes, the two groups of exhaust fans are arranged in opposite directions and the two exhaust fans in the same group are arranged in opposite directions;

[0046] The control unit is also used to control the exhaust fan to start when the temperature sensor detects that the temperature exceeds a preset value;

[0047] An exhaust fan can be installed inside the second box body. When the temperature sensor detects that the temperature exceeds a preset value, the control unit controls the exhaust fan to start. After the exhaust fan is started, the exhaust fan inside the second box body at one end starts to drive the airflow along the external environment through the air window and the second box body into the interior of the UPS body, while the exhaust fan inside the second box body at the other end starts to drive the airflow along the interior of the UPS body through the second box body and the air window to be discharged, thereby forming an airflow circulation to dissipate heat inside the UPS body. Therefore, when the circuit temperature is too high during the circuit connection process, the inside of the UPS body can be cooled, which is beneficial to avoid safety hazards caused by excessive temperature, thereby helping to improve the safety of the UPS body during use.

[0048] Preferably, the switch assembly comprises:

[0049] Four first boxes are slidably mounted on the outer walls of the four control switches respectively;

[0050] Four electric push rods are respectively fixed on the outer walls of the four control switches;

[0051] The ends of the telescopic rods of the four electric push rods are fixedly connected to the inner walls of the four first boxes respectively;

[0052] Four second pressure sensors are respectively fixed on the outer walls of the four first boxes, and when the first box pushes the control switch to close, the second pressure sensors are pressurized;

[0053] The control unit is also used to control the electric push rods corresponding to the other second pressure sensors to start when one of the second pressure sensors is pressurized, so as to drive the corresponding first box to move and push the corresponding control switch to open;

[0054] After the electric push rod is started, the first box body is pushed to move through the telescopic rod. When the first box body moves upward, the control switch is pushed to switch to the closing state. When the first box body moves downward, the control switch is pushed to switch to the opening state.

[0055] For example, when the first box body moves upward to push the second switch to switch to the closed state, the first box body pushes the second switch upward, and the second switch squeezes the second pressure sensor on the first box body, so that the second pressure sensor is pressurized, and the control unit controls the first switch, the third switch and the fourth switch to switch to the open state according to the closing pressure information generated after the second pressure sensor is pressurized, which is beneficial to automatically disconnect the connection of the remaining circuits when a certain circuit is switched to be connected, so as to maintain the single connection of the circuit and avoid the situation where multiple circuits are connected at the same time to cause short circuit or other faults, thereby helping to improve the safety of the power switching process.

[0056] In a second aspect, a control method for a UPS main bypass switching device is provided, the control method comprising the following steps:

[0057] The control unit acquires switching pressure information from any one of the first pressure sensors;

[0058] The control unit obtains the closing information of the control switch corresponding to the first pressure sensor;

[0059] When the control unit simultaneously obtains the switching pressure information and the closing information, the control unit generates detection switching control information, and the detection switching control information is used to control the switch assembly to start, so as to control the control switches other than the control switch corresponding to the first pressure sensor to switch and close according to a priority order, and the priority order is in descending order of the first switch, the second switch, the third switch and the fourth switch;

[0060] The control unit sends the detection switching control information to the switch component to control the switch component to start;

[0061] When the pushing block pushes the pushing plate, the first pressure sensor is squeezed. After the first pressure sensor is pressed, switching pressure information is generated, and the switching pressure information is sent to the control unit. At this time, the control unit obtains the state of the control switch corresponding to the circuit connected to the pressed first pressure sensor. When the control switch corresponding to the pressed first pressure sensor is in a closed state, the control unit obtains the closing information. When the control unit obtains the switching pressure information and the closing information at the same time, the control unit generates detection switching control information according to the switching pressure information and the closing information, and the control unit sends the detection switching control information to the switch assembly to control the control switches except the control switch corresponding to the first pressure sensor to switch and close according to the priority order.

[0062] Preferably, it also includes:

[0063] The control unit acquires high temperature information from the temperature sensor;

[0064] The control unit generates high-temperature switching control information according to the high-temperature information, and the high-temperature switching control information is used to control the switch assembly to start, so as to control the control switches among the control switches except the control switches corresponding to the first pressure sensor generating the switching pressure information and the control switches currently connected to the control switch to switch on according to the priority order;

[0065] The control unit sends the high temperature switching control information to the switch component to control the switch component to start;

[0066] The temperature sensor detects the temperature of the connected space. When the temperature sensor detects that the temperature in the connected space is higher than a preset value, the temperature sensor generates high temperature information and sends the high temperature information to the control unit. After receiving the high temperature information, the control unit generates high temperature switching control information according to the high temperature information. Subsequently, the control unit sends the high temperature switching control information to the switch assembly to control the control switches except the control switches corresponding to the first pressure sensor that generates the switching pressure information and the existing connected control switches to switch on according to the priority order.

[0067] In summary, by switching the circuit, it is beneficial to switch the circuit in a high temperature state, which is beneficial to avoid the situation where the circuit is connected for a long time in a high temperature environment to cause safety hazards, thereby improving the safety of the UPS body during use.

[0068] Preferably, it also includes:

[0069] The control unit acquires closing pressure information from the second pressure sensor;

[0070] The control unit generates opening control information according to the closing pressure information, and the opening control information is used to control the switch assembly to start, so as to control the control switches among the control switches except the control switch corresponding to the second pressure sensor generating the closing pressure information to switch on according to a priority order;

[0071] The control unit sends the gate opening control information to the switch component to control the switch component to start;

[0072] When the switch component switches a control switch to a closed state, the corresponding second pressure sensor is pressurized. After being pressurized, the second pressure sensor generates closing pressure information and sends the closing pressure information to the control unit. After receiving the closing pressure information, the control unit generates opening control information according to the closing pressure information and sends the opening control information to the switch component to control the switch component to start controlling the control switches except the control switch corresponding to the second pressure sensor to switch to close.

[0073] Compared with the prior art, the present invention has the following beneficial effects: the present invention detects the aging state of the circuit by regularly detecting the setting of the components, regularly detecting the voltage and current during the use of the circuit and the temperature during the use of the circuit, and issues a warning to the user so that the user can replace or repair the aged or faulty circuit, thereby helping to avoid the situation where the unused circuit is not used for a long time and the circuit is gradually aged or damaged, causing the UPS body to be unable to bear the load during the main bypass switching due to the damage of the circuit, thereby causing a safety hazard during the use of the UPS body, thereby helping to improve the safety of the UPS body during the main bypass switching process.

DETAILED DESCRIPTION

[0084] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0085] like Figures 2 to 9 A UPS main bypass switching device shown includes a UPS body 1, wherein the UPS body 1 includes four control switches for controlling the connection of various circuits, the four control switches are a first switch 101, a second switch 102, a third switch 103 and a fourth switch 104, and further includes:

[0086] The first mounting plate 2 is fixed inside the UPS body 1. A transverse partition 201 is fixed on the side wall of the first mounting plate 2. The transverse partition 201 divides the inside of the UPS body 1 into a detection space and a communication space. The control switches are all located in the communication space.

[0087] A second mounting plate 3, fixed inside the detection space;

[0088] A periodic detection component is mounted on the second mounting plate 3 and is used to connect the circuit connected to the control switch to detect the circuit;

[0089] A control unit, used for periodically starting the periodic detection component to detect the circuit connected to the control switch;

[0090] When the main power supply is in normal working condition, the bypass and backup power supplies are both in standby condition. When the main power supply is in normal working condition for a long time, the bypass and backup power supplies are also idle for a long time. When the circuit is not in use for a long time, the aging and damage of the circuit are not known. At this time, if the main power supply is cut off and the circuit jumps to the bypass or backup power supply, the aging circuit will cause the circuit to be unable to bear the load, thereby increasing the risk of the circuit during use, thereby affecting the safety of the circuit use;

[0091] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the four control switches are respectively a first switch 101, a second switch 102, a third switch 103 and a fourth switch 104. The first switch 101, the second switch 102, the third switch 103 and the fourth switch 104 are respectively a normal mode switch, a bypass mode switch, a backup mode switch and a maintenance mode switch. The normal mode switch, the bypass mode switch, the backup mode switch and the maintenance mode switch correspond to four circuits, namely, a normal mode circuit, a bypass mode circuit, a backup mode circuit and a maintenance mode circuit. When the four control switches are respectively closed, the corresponding circuits are controlled to be connected.

[0092] The four control switches and the corresponding circuits are installed inside the communication space, and the circuits corresponding to the four control switches extend into the detection space, so that the periodic detection component can be connected to the four circuits to detect them;

[0093] When the UPS body 1 is working, the control unit starts the periodic detection component at a fixed time. After the periodic detection component is started, the circuits connected to the four control switches are detected in turn, so that when the periodic detection component is connected to a certain circuit, the circuit can be connected to the circuit detector to detect the voltage and current during the use of the circuit and the temperature during the use of the circuit, so as to detect the aging state of the circuit. When it is detected that any circuit in the bypass mode circuit, the backup mode circuit and the maintenance mode circuit is aged or fails and affects the use of the circuit, a warning can be issued to the user, and the corresponding aged or failed circuit is marked so that the user can replace or repair the aged or failed circuit, which is beneficial to avoid the circuit being gradually aged or damaged when the unused circuit is not used for a long time, so that the UPS body 1 cannot bear the load due to the damage of the circuit when the main bypass switch is performed, thereby causing a safety hazard during the use of the UPS body 1, which is beneficial to improve the safety of the UPS body 1 during the main bypass switching process.

[0094] As an optional embodiment, the periodic detection component includes:

[0095] The rotating cylinder 5 is rotatably mounted on the side wall of the second mounting plate 3. A circuit detector for detecting the circuit is installed inside the rotating cylinder 5. Connectors connected to the two poles of the circuit detector are symmetrically fixed on the side wall of the rotating cylinder 5.

[0096] Two vacant connectors 401 are symmetrically fixed on the side wall of the second mounting plate 3 with the rotating cylinder 5 as the center;

[0097] Four groups of detection connectors 402, two detection connectors 402 form a group, and are fixed on the side wall of the second mounting plate 3 in a circular array with the rotating cylinder 5 as the center, and each group of detection connectors 402 is respectively connected to the two end circuits of the circuit connected to the four control switches;

[0098] A driving assembly is mounted on the side wall of the second mounting plate 3, and is used to drive the rotating drum 5 to rotate, so that after the rotating drum 5 rotates, it is connected to each group of detection connectors 402 through the connectors to detect each circuit;

[0099] A circuit breaker assembly, mounted on the side wall of the rotating drum 5, for disconnecting the circuit from the power source when the rotating drum 5 is connected to the circuit via the connector;

[0100] The driving assembly can drive the rotating cylinder 5 to rotate, and when the rotating cylinder 5 rotates, the connecting head is driven to rotate. When the connecting head rotates to connect with the vacant connecting head 401, the circuit detector inside the rotating cylinder 5 is in an vacant closed state. When the connecting head rotates to connect with the detection connecting head 402, the four groups of detection connecting heads 402 correspond to four circuits of a normal mode circuit, a bypass mode circuit, a backup mode circuit and a maintenance mode circuit respectively.

[0101] For example, when the connector is rotated to align with the detection connector 402 corresponding to the bypass mode circuit corresponding to the second switch 102 (i.e., the bypass mode switch), the connector is connected to the detection connector 402, so that the circuit detector can be connected to the bypass mode circuit, thereby detecting the bypass mode circuit. At this time, the disconnection component disconnects the connection of the bypass mode circuit, so that the bypass mode circuit is connected to the circuit detector alone, so that the bypass mode circuit is disconnected from the power supply, which is conducive to avoiding interference of the bypass mode circuit power supply connection to the circuit detector during the process of detecting the bypass mode circuit;

[0102] When the rotating drum 5 is not rotated to the point where the detection connector 402 is connected through the connector to connect the circuit, the two detection connectors 402 in the same group are connected through the corresponding circuit breaker components to connect the circuit, so that the normal mode circuit, the bypass mode circuit, the backup mode circuit and the maintenance mode circuit are respectively in a normal connection state, and the circuit is opened and closed only by the first switch 101, the second switch 102, the third switch 103 and the fourth switch 104. Therefore, when the rotating drum 5 is rotated to the point where the detection connector 402 is connected through the connector, the circuit breaker component is disconnected, and the two ends of the detection connector 402 are connected to the two connectors on the rotating drum 5. At this time, the parts of the normal mode circuit, the bypass mode circuit, the backup mode circuit and the maintenance mode circuit that need to be tested are connected to the circuit tester to test the circuit;

[0103] The circuit tester is an instrument for testing the power supply voltage of the circuit, etc. It is a commonly used instrument in the prior art and will not be described in detail here;

[0104] When the driving assembly drives the rotating drum 5 to rotate, the circuit detector detects the normal mode circuit, bypass mode circuit, backup mode circuit and maintenance mode circuit corresponding to the first switch 101, the second switch 102, the third switch 103 and the fourth switch 104 in turn, thereby helping to avoid accidental damage to the circuit when the circuit is idle for a long time, resulting in safety hazards during the main bypass switching of the UPS body 1.

[0105] As an optional embodiment, the driving component includes:

[0106] The first gear 501 is fixed on the outer wall of the rotating cylinder 5;

[0107] The motor 503 is fixed on the side wall of the second mounting plate 3. The output shaft of the motor 503 is fixed with a second gear 502, and the second gear 502 is meshed with the first gear 501;

[0108] After the motor 503 is started, it drives the second gear 502 to rotate through the output shaft, the second gear 502 drives the first gear 501 meshing therewith to rotate, the first gear 501 drives the rotating cylinder 5 to rotate, and when the rotating cylinder 5 rotates, it drives the connector to rotate, thereby switching to the normal mode circuit, bypass mode circuit, backup mode circuit and maintenance mode circuit in sequence for connection and detection.

[0109] As an optional embodiment, the circuit breaker assembly includes:

[0110] A plurality of fixing frames 9 are arranged corresponding to the detection connectors 402 and fixed on the side wall of the second mounting plate 3. A second connecting piece 10 is rotatably mounted inside the fixing frames 9.

[0111] A plurality of first connection pieces 8 are arranged corresponding to the detection connection heads 402 and fixed on the side walls of the corresponding detection connection heads 402. The first connection pieces 8 are in contact with the second connection pieces 10 to form an electrical connection.

[0112] A plurality of push plates 11 are arranged corresponding to the second connecting pieces 10 and fixed to the top of the corresponding second connecting pieces 10. An elastic component for pushing the push plates 11 to reset is installed between the push plates 11 and the fixing frame 9.

[0113] The straight rod 6 is fixed on the side wall of the rotating cylinder 5. Push blocks 7 are fixed at both ends of the straight rod 6. Before the connector is connected to the detection connector 402, the push block 7 pushes the push plate 11 to drive the second connecting piece 10 to rotate and disconnect the electrical connection with the circuit.

[0114] The rotating cylinder 5 rotates to drive the straight rod 6 to rotate, and the straight rod 6 drives the push block 7 to rotate;

[0115] For example, before the connector rotates to align and connect with the two detection connectors 402 connected to the bypass mode circuit, the push block 7 rotates and pushes the push plates 11 corresponding to the two detection connectors 402. After the push plate 11 is pushed, it drives the second connection piece 10 to rotate, so that the second connection piece 10 rotates to disengage from the first connection piece 8, so that the second connection piece 10 is disconnected from the first connection piece 8 and the connection between the bypass mode circuit and the power supply is disconnected. When the push block 7 pushes the push plate 11 to flip, the elastic component is compressed. When the connector rotates to align and connect with the two detection connectors 402 connected to the bypass mode circuit, the push block 7 presses against the push plate 11, so as to maintain the state where the second connection piece 10 is disengaged from the first connection piece 8, so as to maintain the circuit disconnected, which is conducive to disconnecting the bypass mode circuit from the power supply when the bypass mode circuit is detected and detecting the bypass mode circuit alone;

[0116] In summary, during the process of testing a circuit, the circuit can be disconnected from the power supply so that the circuit is connected to the circuit tester alone, which is beneficial to improving the accuracy of testing the circuit.

[0117] The elastic components include:

[0118] A fixing plate 13, fixed on the side wall of the fixing frame 9;

[0119] The spring 12 is fixed between the fixed plate 13 and the push plate 11;

[0120] When the pushing plate 11 is pushed, the pushing plate 11 pushes the spring 12 to compress, so that when the pushing block 7 moves to disengage from the pushing plate 11, the pushing plate 11 can be pushed back to its original position under the elastic force of the spring 12, thereby restoring the connection between the second connecting piece 10 and the first connecting piece 8 to restore the connection of the circuit.

[0121] As an optional embodiment, it also includes:

[0122] A plurality of first pressure sensors 14 are arranged one by one corresponding to the push plates 11 and fixed on the side walls of the corresponding push plates 11. When the push block 7 pushes the push plate 11, the first pressure sensors 14 are pressurized;

[0123] Four switch assemblies are arranged corresponding to the four control switches and are used to automatically close or open the four control switches;

[0124] The control unit is also used to control the switch assembly so that any one of the first switches 101 and the second switch 102 that is not connected to the detection connector 402 corresponding to the pressurized first pressure sensor 14 remains in a closed state when any one of the first pressure sensors 14 is pressurized;

[0125] When the pushing block 7 pushes the pushing plate 11, the first pressure sensor 14 is pressurized;

[0126] For example, when the push block 7 pushes the push plate 11 corresponding to the detection connector 402 connected to the bypass mode circuit, the first pressure sensor 14 installed on the push plate 11 is pressurized. Since the first switch 101 is connected to the normal mode circuit and the second switch 102 is connected to the bypass mode circuit, the second switch 102 corresponds to the bypass mode circuit, that is, it is connected to the bypass mode circuit. After the first pressure sensor 14 is pressurized, the control unit controls the first switch 101 to close according to the switching pressure information of the first pressure sensor 14 being pressurized. After the first switch 101 is closed, the second switch 102, the third switch 103 and the fourth switch 104 are controlled to open.

[0127] In summary, when testing a circuit, the control unit can control the remaining circuits to be connected to maintain the normal operation of the device, which is beneficial to avoid the situation where the device cannot operate normally due to the circuit being disconnected for testing when a certain circuit is being tested, which is beneficial to maintain the normal operation of the setting through circuit switching.

[0128] As an optional embodiment, it also includes:

[0129] The temperature sensor 21 is fixed to the top of the transverse partition 201 and is used to detect the internal temperature of the connected space;

[0130] The control unit is also used to control the switch assembly so that the four control switches perform circuit switching according to the priority when the temperature sensor 21 detects that the temperature exceeds the preset value, and the priority order is descending to the first switch 101, the second switch 102, the third switch 103 and the fourth switch 104;

[0131] The temperature sensor 21 can detect the internal temperature of the connected space. The user inputs a preset temperature value through the user end of the control unit. When the temperature detected by the temperature sensor 21 exceeds the preset temperature value, the control unit controls the circuit to switch so that the circuit in use can be disconnected when the temperature rises, and the remaining circuits are switched to be connected at the same time, which is conducive to automatic switching when the circuit temperature is too high to cause safety hazards, thereby helping to avoid the situation where the circuit temperature is too high during long-term use and causes safety hazards, thereby helping to improve the safety of the UPS body 1 when in use;

[0132] For example, when the first switch 101 is in the closed state, the normal mode switch is in the connected working state. At this time, the temperature sensor 21 detects the internal temperature of the connected space. When it is detected that the temperature exceeds the preset temperature value, the control unit controls the switch component to switch the first switch 101 to the open state. At this time, according to the priority of the second switch 102, the third switch 103 and the fourth switch 104, the control unit controls the switch component to switch the second switch 102 to the closed state, so that the circuit switches to the bypass mode circuit. If the periodic detection component is detecting the bypass mode circuit corresponding to the second switch 102 at this time, the control unit controls the switch component to switch the third switch 103 to the closed state, so that the circuit switches to the backup mode circuit, which is beneficial to avoid the situation where the circuit temperature is too high during long-term use and causes safety hazards, thereby helping to improve the safety of the UPS body 1 when in use.

[0133] As an optional embodiment, it also includes:

[0134] Two second boxes 18 are symmetrically fixed at the two ends of the transverse partition, and the opposite ends of the two second boxes 18 are provided with ventilation windows 20;

[0135] Four exhaust fans 19, two in a group, the two groups of exhaust fans 19 are symmetrically fixed to the upper and lower ends of the two second boxes 18, the two groups of exhaust fans 19 are arranged in opposite directions and the two exhaust fans 19 in the same group are arranged in opposite directions;

[0136] The control unit is also used to control the exhaust fan 19 to start when the temperature sensor 21 detects that the temperature exceeds a preset value;

[0137] An exhaust fan 19 can be installed inside the second box body 18. When the temperature sensor 21 detects that the temperature exceeds a preset value, the control unit controls the exhaust fan 19 to start. After the exhaust fan 19 is started, inside the second box body 18 at one end, the exhaust fan 19 starts to drive the airflow along the external environment through the air window 20 and the second box body 18 into the inside of the UPS body 1, while inside the second box body 18 at the other end, the exhaust fan 19 starts to drive the airflow along the inside of the UPS body 1 through the second box body 18 and the air window 20 to be discharged, thereby forming an airflow circulation to dissipate the heat inside the UPS body 1. Therefore, when the circuit temperature is too high during the circuit connection process, the heat inside the UPS body 1 can be dissipated, which is beneficial to avoid the safety hazards caused by excessive temperature, thereby helping to improve the safety of the UPS body 1 during use.

[0138] As an optional embodiment, the switch assembly includes:

[0139] Four first boxes 15 are slidably mounted on the outer walls of four control switches respectively;

[0140] Four electric push rods 16 are respectively fixed on the outer walls of four control switches;

[0141] The ends of the telescopic rods of the four electric push rods 16 are fixedly connected to the inner walls of the four first boxes 15 respectively;

[0142] Four second pressure sensors 17 are respectively fixed on the outer walls of the four first boxes 15. When the first box 15 pushes the control switch to close, the second pressure sensors 17 are pressurized;

[0143] The control unit is also used to control the electric push rods 16 corresponding to the other second pressure sensors 17 to start when one of the second pressure sensors 17 is pressurized, so as to drive the corresponding first box 15 to move and push the corresponding control switch to open;

[0144] After the electric push rod 16 is started, it pushes the first box body 15 to move through the telescopic rod. When the first box body 15 moves upward, it pushes the control switch to switch to the closed state. When the first box body 15 moves downward, it pushes the control switch to switch to the open state.

[0145] For example, when the first box body 15 moves upward to push the second switch 102 to switch to the closed state, the first box body 15 pushes the second switch 102 upward, and the second switch 102 squeezes the second pressure sensor 17 on the first box body 15, so that the second pressure sensor 17 is pressurized, and the control unit controls the first switch 101, the third switch 103 and the fourth switch 104 to switch to the open state according to the closing pressure information generated after the second pressure sensor 17 is pressurized, which is beneficial to automatically disconnect the connection of the remaining circuits when a certain circuit is switched to be connected, so as to maintain the single connection of the circuit, avoid the situation where multiple circuits are connected at the same time to cause short circuit or other faults, and thus help to improve the safety of the power switching process.

[0146] like Figure 1 A control method for a UPS main bypass switching device is shown, the control method comprising the following steps:

[0147] The control unit obtains the switching pressure information from any first pressure sensor 14;

[0148] The control unit obtains the closing information of the control switch corresponding to the first pressure sensor 14;

[0149] When the control unit simultaneously obtains the switching pressure information and the closing information, the control unit generates detection switching control information, and the detection switching control information is used to control the switch assembly to start, so as to control the control switches other than the control switch corresponding to the first pressure sensor 14 to switch and close according to the priority order, and the priority order is in descending order of the first switch 101, the second switch 102, the third switch 103 and the fourth switch 104;

[0150] The control unit sends the detection switching control information to the switch component to control the switch component to start;

[0151] When the push block 7 moves toward any one of the push plates 11, the push block 7 pushes the push plate 11, squeezing the first pressure sensor 14. After the first pressure sensor 14 is pressurized, it generates switching pressure information, and sends the switching pressure information to the control unit. At this time, the control unit obtains the state of the control switch corresponding to the circuit connected to the pressurized first pressure sensor 14. When the control switch corresponding to the pressurized first pressure sensor 14 is in the closed state, the control unit obtains the closing information. When the control unit obtains the switching pressure information and the closing information at the same time, the control unit generates the detection switching control information according to the switching pressure information and the closing information, and the control unit sends the detection switching control information to the switch assembly to control the control switches except the control switches corresponding to the first pressure sensor 14 to switch and close according to the priority order.

[0152] For example, when the control switch corresponding to the pressurized first pressure sensor 14 is the second switch 102, the control unit controls the first switch 101, the third switch 103 and the fourth switch 104 to switch on and off according to the priority order, and the priority order is in descending order of the first switch 101, the second switch 102, the third switch 103 and the fourth switch 104, that is, the control unit controls the first switch 101 to switch to the closed state to switch the circuit to the normal mode circuit.

[0153] As an optional embodiment, it also includes:

[0154] The control unit obtains high temperature information from the temperature sensor 21;

[0155] The control unit generates high-temperature switching control information according to the high-temperature information, and the high-temperature switching control information is used to control the start-up of the switch assembly to control the control switches except the control switches corresponding to the first pressure sensor 14 that generates the switching pressure information and the existing connected control switches to switch and close according to the priority order;

[0156] The control unit sends high temperature switching control information to the switch component to control the switch component to start;

[0157] The temperature sensor 21 detects the temperature of the connected space. When the temperature sensor 21 detects that the temperature in the connected space is higher than a preset value, the temperature sensor 21 generates high temperature information and sends the high temperature information to the control unit. After receiving the high temperature information, the control unit generates high temperature switching control information according to the high temperature information. Then, the control unit sends the high temperature switching control information to the switch assembly to control the control switches except the control switches corresponding to the first pressure sensor 14 that is pressurized to generate the switching pressure information and the existing connected control switches to switch and close according to the priority order.

[0158] For example, when the periodic detection component detects the bypass mode circuit, the circuit corresponding to the first pressure sensor 14 that is under pressure to generate the switching pressure information is the bypass mode circuit, that is, the first pressure sensor 14 that is under pressure to generate the switching pressure information corresponds to the second switch 102, and at this time, the existing connected circuit is a normal mode circuit, that is, corresponding to the first switch 101, and at this time, the temperature sensor 21 detects that the temperature of the connected space exceeds the preset temperature, then the control unit controls the third switch 103 and the fourth switch 104 to switch on according to the priority order, that is, the control unit controls the third switch 103 to switch on, that is, the temperature of the normal mode circuit connected to the first switch 101 rises above the preset value, and when the periodic detection component detects the bypass mode circuit connected to the second switch 102, the control unit controls the circuit to switch to the backup mode circuit for normal operation of the device;

[0159] In summary, by switching the circuit, it is beneficial to switch the circuit in a high temperature state, which is beneficial to avoid the situation where the circuit is connected for a long time in a high temperature environment to cause safety hazards, thereby improving the safety of the UPS body 1 during use.

[0160] As an optional embodiment, it also includes:

[0161] The control unit obtains the closing pressure information from the second pressure sensor 17;

[0162] The control unit generates opening control information according to the closing pressure information, and the opening control information is used to control the switch assembly to start, so as to control the control switches except the control switch corresponding to the second pressure sensor 17 that generates the closing pressure information to switch to close;

[0163] The control unit sends the gate opening control information to the switch assembly to control the switch assembly to start;

[0164] When the switch assembly switches a certain control switch to the closed state, the corresponding second pressure sensor 17 is pressurized, and the second pressure sensor 17 generates closing pressure information after being pressurized, and sends the closing pressure information to the control unit. After receiving the closing pressure information, the control unit generates opening control information according to the closing pressure information, and sends the opening control information to the switch assembly, so as to control the switch assembly to start controlling the control switches except the control switch corresponding to the second pressure sensor 17 that is pressurized to generate the closing pressure information, and switch the control switches to close;

[0165] For example, when the first box body 15 in the switch assembly moves upward to push the first switch 101 to close, the second pressure sensor 17 is pressurized, so that the control unit controls the electric push rods 16 corresponding to the second switch 102, the third switch 103 and the fourth switch 104 to start, pushing the first box body 15 to move downward to push the second switch 102, the third switch 103 and the fourth switch 104 to open, so that when the first switch 101 is closed, the second switch 102, the third switch 103 and the fourth switch 104 are automatically switched to open.

[0166] Working principle of the present invention: four control switches are respectively a first switch 101, a second switch 102, a third switch 103 and a fourth switch 104, the first switch 101, the second switch 102, the third switch 103 and the fourth switch 104 are respectively a normal mode switch, a bypass mode switch, a backup mode switch and a maintenance mode switch, the normal mode switch, the bypass mode switch, the backup mode switch and the maintenance mode switch correspond to four circuits, namely a normal mode circuit, a bypass mode circuit, a backup mode circuit and a maintenance mode circuit, respectively, and when the four control switches are respectively closed, the corresponding circuits are controlled to be connected;

[0167] The four control switches and the corresponding circuits are installed inside the communication space, and the circuits corresponding to the four control switches extend into the detection space, so that the periodic detection component can be connected to the four circuits to detect them;

[0168] When the UPS body 1 is working, the control unit starts the periodic detection component at a fixed time. After the periodic detection component is started, the circuits connected to the four control switches are detected in turn, so that when the periodic detection component is connected to a certain circuit, the circuit can be connected to the circuit detector to detect the voltage and current during the use of the circuit and the temperature during the use of the circuit, so as to detect the aging state of the circuit. When it is detected that any circuit in the bypass mode circuit, the backup mode circuit and the maintenance mode circuit is aged or fails and affects the use of the circuit, a warning can be issued to the user, and the corresponding aged or failed circuit is marked so that the user can replace or repair the aged or failed circuit, which is beneficial to avoid the circuit being gradually aged or damaged when the unused circuit is not used for a long time, so that the UPS body 1 cannot bear the load due to the damage of the circuit when the main bypass switch is performed, thereby causing a safety hazard during the use of the UPS body 1, which is beneficial to improve the safety of the UPS body 1 during the main bypass switching process.
