Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a frame circuit breaker energy storage control device and system. Background Art

[0002] A frame circuit breaker is a mechanical switching device that can connect, carry and disconnect current under normal circuit conditions, and can also connect, carry for a certain time and disconnect current under specified abnormal circuit conditions.

[0003] Currently, most frame circuit breakers' microswitches are connected directly to the input power supply after being connected to the load indicator light. When the frame circuit breaker is charging, the microswitch turns on the motor and turns off the load indicator light. When the frame circuit breaker completes charging, the microswitch turns off the motor and turns on the load indicator light. In this case, if the user incorrectly connects the load indicator light wiring, it can easily burn out the microswitch, motor, and other components, causing a safety accident.

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application.

[0062] Currently, most existing frame circuit breakers use microswitches to control the start and stop of motors to achieve energy storage. When the microswitch is in the energy storage position, it closes, connecting the motor power supply and the circuit breaker's energy storage mechanism to store energy. When energy storage is complete, the microswitch opens, stopping the motor. This method, which directly connects and disconnects the motor with a microswitch, is quite damaging. Failures are often caused by contact adhesion, which prevents the motor from shutting off, ultimately causing the motor to burn out or damage the energy storage mechanism.

[0063] At the same time, since the micro switch of most frame circuit breakers is directly connected to the input power supply after being connected to the load indicator light, when the frame circuit breaker is charging, the micro switch turns on the motor and disconnects the load indicator light. When the frame circuit breaker completes charging, the micro switch disconnects the motor and turns on the load indicator light. In this case, if the user connects the load indicator light wire incorrectly, such as connecting the load indicator light wire to the power neutral line or forgetting to connect the load indicator light wire, it is easy to burn out the micro switch, motor, etc., causing a safety accident.

[0064] Based on the above research, this embodiment provides a frame circuit breaker energy storage control device and system. By providing an input detection module, a control module, and a drive module, the input detection module is electrically connected to the control module and the drive module. The input detection module is used to send a detection signal to the control module. Based on the detection signal, the control module is used to determine the connection status between the input detection module and the input power supply, and control the operation of the drive module based on this connection status. In this way, by detecting the connection status with the input power supply, the drive module can be controlled to stop operation if an error occurs in the connection status. This effectively avoids damage to components such as the drive module due to wiring errors, effectively protects the drive module, and improves the safety of the frame circuit breaker.

[0065] See also Figure 1 , Figure 1 A structural diagram of the frame circuit breaker energy storage control device provided in this embodiment is shown as follows: Figure 1 As shown, the frame circuit breaker energy storage control device provided in this embodiment includes an input detection module 10, a control module 20 and a drive module 30. The input detection module 10, the control module 20 and the drive module 30 are electrically connected.

[0066] The input detection module 10 is used to send a detection signal to the control module 20. The control module 20 is used to determine the connection status between the input detection module 10 and the input power supply according to the detection signal, and control the operation of the driving module 30 according to the connection status.

[0067] The input power supply may be an AC power supply or a DC power supply. The input power supply is used to provide power to the frame circuit breaker and the drive module 30, the control module 20, etc. in the frame circuit breaker energy storage control device, and the frame circuit breaker realizes energy storage by controlling the operation of the drive module 30.

[0068] In order to avoid damage to the driving module due to wiring errors, in this embodiment, an input detection module 10 is provided, and the input detection module 10 is electrically connected to the input power supply, the driving module 30 and the control module 20. A detection signal is sent to the control module 20 through the input detection module 10, so that the control module 20 can determine the connection status of the input detection module 10 and the input power supply based on the detection signal, and control the operation of the driving module 30 based on the connection status.

[0069] In this embodiment, the connection status of the input detection module 10 and the input power supply includes short circuit, open circuit and normal connection. When the connection status of the input detection module 10 and the input power supply is short circuit or open circuit, it means that there is a wiring error in the input power supply and the frame circuit breaker cannot store energy normally. When the input detection module 10 and the input power supply are normally connected, it means that the input power supply and the input detection module are correctly connected, and the frame circuit breaker can operate normally to store energy.

[0070] When the control module 20 detects that the connection status between the input detection module 10 and the input power supply is short-circuited or open-circuited according to the detection signal, the drive module 30 is controlled not to operate. When the control module 20 detects that the connection status between the input detection module 10 and the input power supply is normally connected according to the detection signal, the drive module 30 is controlled to operate. In this way, damage to the drive module 30 caused by wiring errors can be avoided, and the normal operation of the frame circuit breaker can be avoided from being affected by wiring errors, thereby improving safety performance.

[0071] The frame circuit breaker energy storage control device provided in this embodiment can effectively identify whether there is a wiring error at the input end by providing an input detection module. In the event of a wiring error, the drive module is controlled not to operate, thereby avoiding damage to the drive module caused by the wiring error and improving safety performance.

[0072] Optionally, in order to achieve control over each module, in this embodiment, the control module 20 can be a single-chip microcomputer, which collects signals through the single-chip microcomputer and controls each module through the I / O interface, thereby achieving energy storage for the frame circuit breaker and protecting each module when the input terminal is connected incorrectly.

[0073] Please refer to Figure 2 , Figure 2 This is a schematic diagram of an interface of the control module 20 provided in this embodiment. Figure 2 As shown, the I / O interfaces of the control module 20 provided in this embodiment include an HVDC_AD interface, a MOTO_AD interface, a Status ON interface, a Status NC interface, a P_AD interface, a PWM interface, a Fault_Relay interface, and a Dr_P interface. The P_AD interface, the Dr_P interface, and the Fault_Relay interface are used to connect to the input detection module; the Status ON interface, the Status NC interface, the MOTO_AD interface, and the PWM interface are used to connect to the drive module; and the HVDC_AD interface is used to connect to the detection module.

[0074] It is understandable that in this embodiment, the control module 20 may also include some conventional peripheral related devices, such as Figure 2 The resistor R25, the resistor R15, the capacitor C9, the capacitor C11, the capacitor C12 and the LED1, the working principles and functions of the above components can be found in existing technical information and will not be elaborated here.

[0075] The frame circuit breaker processing device provided in this embodiment collects signals through the control module and controls each module through its I / O interface, thereby realizing energy storage of the frame circuit breaker and protecting each module in the event of a wrong connection of the input terminal.

[0076] To check the input detection module and the input power connection status, please refer to Figure 3 In this embodiment, the input detection module 10 includes a load resistor R2 and a detection resistor R5.

[0077] The load resistor R2 is electrically connected to the detection resistor R5 , and the detection resistor R5 is electrically connected to the control module 20 .

[0078] The control module 20 is used to obtain the voltage of the detection resistor R5 and determine the connection status of the load resistor R2 and the input power supply according to the voltage of the detection resistor R5.

[0079] like Figure 3 As shown, the input power supply includes a neutral line (N) and a live line (L), one end of the detection resistor R5 is connected to the live line, and the other end is connected to the P_AD interface of the control module 20.

[0080] In this embodiment, the load resistor R2 can be an indicator light. When the load resistor R2 is normally connected, one end of the load resistor R2 is connected to the neutral line of the input power supply, and the other end is electrically connected to the detection resistor R5, that is, the load resistor R2 and the detection resistor R5 are connected in series and then connected in parallel at both ends of the input power supply.

[0081] If the user incorrectly connects the load resistor R2, causing it to short-circuit, the detection resistor R5 is directly connected to the input power supply, which is equivalent to the detection resistor R5 being connected in parallel across the input power supply. Since there is no voltage divider provided by the load resistor R2, the voltage across the detection resistor R5 will be higher.

[0082] If the load resistor R2 is not connected, that is, the load resistor R2 and the input power supply are open, then no current flows into the detection resistor R5 and no voltage value is generated across the detection resistor R5.

[0083] If the load resistor R2 is connected normally, the power current of the input power supply flows from the load resistor R2 into the detection resistor R5, and then flows back to the input power supply through the detection resistor R5. At this time, it is equivalent to connecting the detection resistor R5 and the load resistor R2 in series and then in parallel across the input power supply. Due to the voltage division of the load resistor R2, the voltage of the detection resistor R5 will decrease.

[0084] Based on this, this embodiment obtains the voltage of the detection resistor R5 through the P_AD interface of the control module, and the connection status of the load resistor R2 and the input power supply can be determined according to the voltage of the detection resistor R5.

[0085] In an optional implementation, this embodiment may first detect the voltage of the detection resistor R5 when the load resistor R2 is normally connected, and obtain the voltage value of the detection resistor R5 when the load resistor R2 is normally connected, and then set the voltage range according to the voltage value of the detection resistor R5 when the load resistor R2 is normally connected. If the voltage value of the detection resistor R5 is detected to be higher than the voltage range, it can be determined that the connection status of the load resistor R2 and the input power supply is short-circuited. If the voltage value of the detection resistor R5 is detected to be within the voltage range, it is determined that the connection status of the load resistor R2 and the input power supply is normally connected. Correspondingly, if the voltage value of the detection resistor R5 is detected to be 0, it is determined that the connection status of the load resistor R2 and the input power supply is open.

[0086] In an optional embodiment, when setting the voltage range based on the voltage value of the detection resistor R5 when the load resistor R2 is normally connected, the voltage value of the detection resistor R5 can be measured multiple times after the load resistor R2 is normally connected, and the voltage range can be set according to the maximum and minimum values ​​of the voltage values ​​of the detection resistor R5 measured multiple times. The voltage range can also be set according to the average value of the voltage values ​​of the detection resistor R5 measured multiple times, with the standard deviation of the average value ± a set multiple. The set multiple can be set according to actual needs, and this embodiment does not impose any specific restrictions.

[0087] In this embodiment, after the control module 20 obtains the voltage of the detection resistor R5 through the P_AD interface, if it is determined based on the voltage of the detection resistor R5 that the connection state between the load resistor R2 and the input power supply is short-circuited or open-circuited, it is determined that a wiring error exists, and the drive module 30 is controlled not to operate. If it is determined based on the voltage of the detection resistor R5 that the connection state between the load resistor R2 and the input power supply is normally connected, it is determined that no wiring error exists, and the drive module 30 is controlled to operate normally. This prevents the drive module 30 from operating in the case of a wiring error and causing damage to the drive module 30. At the same time, the normal operation of the drive module 30 is ensured when the wiring is normal, thereby realizing energy storage of the frame circuit breaker.

[0088] The frame circuit breaker energy storage control device provided in this embodiment provides an input detection module, a detection resistor is provided in the input detection module, and the voltage of the detection resistor is obtained. Based on the voltage of the detection resistor, the connection status of the load resistor and the input power supply is determined. In this way, whether there is an input wiring error can be effectively identified. When a wiring error occurs, the drive module is controlled not to operate, thereby effectively avoiding damage to the drive module caused by the wiring error.

[0089] In order to protect the circuit and facilitate the connection of the circuit, in this embodiment, as Figure 3As shown, the input detection module 10 may further include circuit components such as a connection terminal P1 , a diode D4 , a protection resistor R9 , and a rectifier bridge D1 .

[0090] Among them, terminal 1 of the wiring terminal is connected to the live wire of the input power supply, terminals 3 and 5 are connected to the neutral wire of the input power supply, terminals 2 and 4 are connected to the rectifier bridge D1, terminal 6 is connected to one end of the diode D4, the other end of the diode D4 is connected to one end of the protection resistor R9, the other end of the protection resistor R9 is connected to one end of the detection resistor R5, and the other end of the detection resistor R5 is connected to the rectifier bridge D1. When load resistor R2 is connected normally, one end of load resistor R2 is connected to the neutral line of the input power supply, and the other end is connected to terminal 5 of terminal block P1. Load resistor R2, terminal block P1, diode D4, protective resistor R9, sense resistor R5, rectifier bridge D1, and the input power supply form a series circuit. At this time, the series circuit has a voltage divider due to load resistor R2, and the voltage value of sense resistor R5 is relatively low. When load resistor R2 is short-circuited, terminal block P1, terminal 5, directly connected to the neutral line of the input power supply, and terminal block P1, diode D4, protective resistor R9, sense resistor R5, rectifier bridge D1, and the input power supply form a series circuit. At this time, the series circuit has no voltage divider effect due to load resistor R2, and the voltage value of sense resistor R5 is relatively high. When load resistor R2 is open-circuited, no current flows through. Load resistor R2, terminal block P1, diode D4, protective resistor R9, sense resistor R5, rectifier bridge D1, and the input power supply do not form a loop, and no voltage is applied to sense resistor R5.

[0091] The frame circuit breaker energy storage control device provided in this embodiment collects the voltage of the detection resistor R5 and detects the connection status of the load and the input power supply based on the voltage of the detection resistor R5. This can effectively identify faulty circuits with incorrect wiring and normal circuits with correct wiring. Furthermore, when controlling the operation of the drive module based on the connection status, damage to the drive module caused by such wiring errors can be effectively avoided.

[0092] In view of the fact that in actual application, the control module 20 only needs to detect the wiring status before performing energy storage work, therefore, in order to facilitate the detection, please continue to refer to Figure 3 In this embodiment, the input detection module further includes a first switch tube Q1.

[0093] The first switch tube Q1 is connected in series with the detection resistor R5 , and after the series connection, is electrically connected to the control module 20 and the load resistor R2 respectively.

[0094] The control module 20 is used to control the conduction state of the first switch tube Q1, and after the first switch tube Q1 is turned on, obtain the voltage of the detection resistor R5, and determine the connection state of the load resistor R2 and the input power supply according to the voltage of the detection resistor R5.

[0095] The first switch Q1 may be a field effect transistor (MOS), a triode, or the like. Optionally, in this embodiment, the first switch is a MOS, with its gate connected to the Dr_P port of the control module 20, its drain connected to the protection resistor R9, and its source connected to the detection resistor R5.

[0096] When the frame circuit breaker needs to store energy, the control module first sends a signal to the first switch tube Q1 to turn on the first switch tube Q1. After the first switch tube Q1 is turned on, the voltage of the detection resistor R5 can be collected to determine whether the load resistor R2 is normally connected based on the voltage of the detection resistor R5.

[0097] If the user misconnects or the load shorts, and terminal 5 of connection terminal P1 is directly shorted to the neutral line of the input power supply, the power supply current flows back to the power supply through diode D4, protection resistor R9, first switch Q1, sense resistor R5, rectifier bridge D1, and terminals 2 and 1 of connection terminal P1. Because the voltage drop across diode D4, first switch Q1, and rectifier bridge D1 is very low and negligible, the protection resistor R9 and sense resistor R5 are equivalently connected in series and then in parallel across the power supply. The voltage across sense resistor R5 is read by the control module's P_AD port. Since load resistor R2 is not acting at this point, the voltage across sense resistor R5 is relatively high.

[0098] If the load resistor R2 is not connected, that is, the load resistor R2 is open to the input power supply, no current returns to the power supply from the branch of the diode D4, the protection resistor R9, the first switch Q1, and the detection resistor R5, and the detection resistor R5 has no voltage value.

[0099] If load resistor R2 is properly connected to the input power supply, the input power current flows back to the input power supply through load resistor R2, terminals 5 and 6 of terminal P1, diode D4, protection resistor R9, first switching transistor Q1, sense resistor R5, rectifier bridge D1, and terminals 2 and 1 of terminal P1. Since the voltage drop across diode D4, first switching transistor Q1, and rectifier bridge D1 is very low and negligible, the sense resistor R5, protection resistor R9, and load resistor R2 are equivalently connected in series, then in parallel across the input power supply. Due to the voltage divider effect of load resistor R2, the voltage across sense resistor R5 will be lower than the voltage when load resistor R2 is short-circuited, and higher than the voltage when load resistor R2 is open-circuited.

[0100] After the control module obtains the voltage value of the detection resistor R5 through the P_AD interface, it can determine whether the voltage value of the detection resistor R5 is within the set voltage range. If the voltage value of the detection resistor R5 is higher than the set voltage range, it is determined that the load resistor R2 is short-circuited, and the control drive module 30 is controlled to not operate. If the voltage value of the detection resistor R5 is zero, it is determined that the load resistor R2 is open-circuited from the input power supply, and the control drive module 30 is controlled to not operate. If the voltage value of the detection resistor R5 is within the set voltage range, it is determined that the load resistor R2 is properly connected to the input power supply, and the control drive module 30 is controlled to operate.

[0101] In this embodiment, after detecting the connection status between the load resistor R2 and the input power supply, the first switch Q1 is turned off. If the connection status between the load resistor R2 and the input power supply is determined to be normal, the driver module 30 is then controlled to operate. If the connection status between the load resistor R2 and the input power supply is determined to be short-circuited or open-circuited, the driver module 30 is then controlled to not operate and wait for the user to reconnect the power supply. It is understandable that after the user completes the reconnection, before energy storage is performed, the first switch Q1 still needs to be turned on to detect the connection status. Only when the detection is normal will the driver module 30 be controlled to operate. In this way, product failures caused by incorrect connection or load short circuit can be prevented.

[0102] In this embodiment, after determining that the load resistor R2 is normally connected to the input power supply and the control module controls the driving module to operate normally, the frame circuit breaker stores energy. In order to monitor the energy storage process of the frame circuit breaker, please continue to refer to Figure 3 The input detection module provided in this embodiment includes a second switch tube Q2 and a relay K1 connected in series.

[0103] The second switch tube Q2 is electrically connected to the control module after being connected in series with the relay K1 . The relay K1 is electrically connected to the load resistor R2 after being connected in series with the second switch tube Q2 .

[0104] The control module 20 is used to control the conduction state of the second switch tube Q2 according to the connection state of the load resistor R2 and the input power supply, and control the opening and closing state of the relay K1 through the conduction state of the second switch tube Q2.

[0105] The second switch Q2 may be a field effect transistor (MOS), a triode, or other switching transistor. Optionally, in this embodiment, the second switch Q2 is a MOS transistor, with a gate connected to the Fault_Relay port of the control module, a drain connected to the relay K1, and a source connected to ground.

[0106] In this embodiment, when the control module 20 determines that the connection between the load resistor R2 and the input power supply is short-circuited or open-circuited, the second switch Q2 is turned off, and the relay K1 is disconnected. When the control module 20 determines that the connection between the load resistor R2 and the input power supply is normal, the relay K1 can be controlled to close as needed. When relay K1 is closed, the power supply current flows back to the input power supply from the load resistor R2 and terminals 5, 6, 2, and 1 of the terminal block P1. The load resistor R2 forms a series circuit with the input power supply. The load resistor R2 is energized and operates, thereby monitoring the entire energy storage process of the frame circuit breaker. For example, if monitoring is required during the energy storage process, the control module 20 can control the second switch Q2 to conduct when the drive module 30 is operating and the frame circuit breaker begins to store energy. When the second switch Q2 is turned on, the relay K1 is energized and closed, and the load resistor R2 operates, i.e., the indicator light is illuminated. For another example, if a prompt is needed when energy storage is complete, the control module 20 can control the second switch Q2 to conduct when the frame circuit breaker completes energy storage. When the second switch Q2 conducts, the relay K1 is energized and closes, and the load resistor R2 operates. For the user, when the load resistor R2 operates, it indicates that the frame circuit breaker is in the process of energy storage or energy storage is complete.

[0107] The frame circuit breaker energy storage control device provided in this embodiment is provided with a second switch tube and a relay. When the load resistor is determined to be short-circuited or open-circuited, the second switch tube is controlled to be cut off and the relay is controlled to be in the disconnected state. When the load resistor is determined to be normally connected, the second switch tube can be controlled to be turned on and the relay can be closed to operate the load resistor during or after energy storage, as required. This can achieve the purpose of preventing incorrect connection of the input terminal while monitoring the energy storage process.

[0108] In order to protect the detection resistor, in this embodiment, please refer to Figure 3 The input detection module includes a first capacitor C5 and a voltage regulator diode D0.

[0109] The first capacitor C5 is connected in parallel with the detection resistor R5 and is used to smooth and filter the current of the detection resistor R5.

[0110] The voltage regulator D0 is connected in parallel with the detection resistor R5 to limit the voltage amplitude of the detection resistor R5.

[0111] The frame circuit breaker energy storage control device provided in this embodiment provides a first capacitor C5 and a voltage regulator diode. The first capacitor C5 smoothes and filters the current of the detection resistor R5, and the voltage regulator diode D0 limits the voltage amplitude of the detection resistor R5, thereby protecting the detection resistor R5.

[0112] It is understandable that in this embodiment, the input detection module 10 may also include some conventional peripheral related devices, such as Figure 3 The resistors R4, R6, R12, R11 and the diode D6, the working principles and functions of the above components can be found in existing technical information and will not be elaborated here.

[0113] In this embodiment, the rectifier bridge D1 is connected to the input power supply to rectify the input power supply. After the input power supply is rectified, it can supply power to other modules through the HVDC port. In order to avoid abnormal input voltage and damage to the circuit. In this embodiment, please refer to Figure 4 The frame circuit breaker energy storage control device further includes a detection module 40 .

[0114] The rectifier bridge is electrically connected to the input power supply and the detection module 40 , and the detection module 40 is electrically connected to the control module 30 .

[0115] The detection module 40 is used to detect the voltage signal after rectification by the rectifier bridge and send the voltage signal to the control module 30 .

[0116] After the rectifier bridge is connected to the input power supply, it is electrically connected to the detection module 40 via the HVDC port. One end of the detection module 40 is connected to the HVDC port of the rectifier bridge D1, and the other end is connected to the control module 40. After the rectifier bridge D1 rectifies the input power supply, the detection module 40 detects the rectified voltage signal of the rectifier bridge D1 and sends the voltage signal to the control module 20. The control module 20 performs a logical judgment. If the control module 20 determines that the rectified voltage signal is not within the set operating voltage range, it indicates that the input voltage is abnormal and may cause damage to the circuit, and then an alarm is issued. If the rectified voltage signal is determined to be within the set operating voltage range, it indicates that the input voltage is normal and the control circuit is operating normally. This can prevent abnormal input voltage from causing damage to the circuit, thereby improving safety performance.

[0117] In an optional embodiment, please refer to Figure 5 The detection module 40 provided in this embodiment can be Figure 5 The circuit diagram shown is as follows: Figure 5As shown, the detection module 40 provided in this embodiment may include a resistor R10, a resistor R13, a resistor R14, a resistor R16, and a capacitor C10. Among them, one end of the resistor R10 is connected to the HVDC port of the rectifier bridge, and the other end is connected to one end of the resistor R13. The other end of the resistor R13 is connected to the resistor R14 and the resistor R16 respectively. After one end of the resistor R14 is connected to the resistor R13, the other end is connected to the HVDC_AD interface of the control module and one end of the capacitor C10. After one end of the resistor R16 is connected to the resistor R13, the other end is grounded and connected to the other end of the capacitor C10. After the voltage signal rectified by the rectifier bridge passes through the resistor R10, the resistor R13, the resistor R14, the resistor R16, and the capacitor C10, it can be sent to the control module through the HVDC_AD interface of the control module, and the control module performs logical judgment.

[0118] The frame circuit breaker energy storage control device provided in this embodiment can effectively avoid abnormal input voltage and damage to the circuit by providing a detection module, thereby improving the safety performance of the circuit.

[0119] Since the voltage required by the electronic components in the drive module and the control module is relatively low, in order to avoid damage to the electronic components due to excessive input voltage, in this embodiment, please refer to Figure 6 The frame circuit breaker energy storage control device provided in this embodiment further includes a power supply module 50 .

[0120] The power module 50 is electrically connected to the rectifier bridge, the drive module 30 and the control module 20 respectively.

[0121] The power module 50 is used to step down the voltage signal rectified by the rectifier bridge and provide power to the driving module and the control module 20 after the voltage is stepped down.

[0122] The power module 50 may be a power circuit composed of a single-chip switching power supply chip, such as Figure 7As shown, the power supply module may include a first power supply circuit (a) and a second power supply circuit (b), wherein the first power supply circuit (a) includes an inductor L1, a capacitor C1, a capacitor C2, a power supply chip U1, a capacitor C3, a resistor R1, a resistor R3, a capacitor C4, an inductor L2, a diode D3, a diode D2, a capacitor C6 and a resistor R8. Among them, the first end of the inductor L1 is connected to the HVDC port of the rectifier bridge D1, and the second end is connected to pin 4 of the power chip U1. The first end of the capacitor C1 is connected to the first end of the inductor L1, and the second end is connected to the second end of the capacitor C2. The first end of the capacitor C2 is connected to the second end of the inductor L1. The second end of the capacitor C1 is connected to the first end of the diode D3 after being connected to the second end of the capacitor C2. The second end of the diode D3 is connected to the common end of pins 5, 6, 7, and 8 of the power chip U1. The first end of the capacitor C3 is connected to pin 1 of the power chip U1. The second end of the capacitor C3 is connected to the common end of pins 5, 6, 7, and 8 of the power chip U1. The first end of the resistor R1 is connected to pin 1 of the power chip U1. The second end of resistor R1 is connected to the second end of diode D2, the first end of diode D2 is connected to the output end, the first end of resistor R3 is connected to pin 1 of power chip U1, the second end of resistor R3 is connected to the common end of pins 5, 6, 7, and 8 of power chip U1, the first end of capacitor C4 is connected to the second end of resistor R1, the second end of capacitor C4 is connected to the common end of pins 5, 6, 7, and 8 of power chip U1, the first end of inductor L2 is connected to the common end of pins 5, 6, 7, and 8 of power chip U1, the second end of inductor L2 is connected to the output end, the first end of capacitor C6 is grounded, the second end of capacitor C6 is connected to the output end, the first end of resistor R8 is grounded, and the second end of resistor R8 is connected to the output end. Pins 1, 2, and 4 of power chip U1 are inputs, and pins 5, 6, 7, and 8 are outputs.

[0123] The voltage signal after rectification by the rectifier bridge passes through the HVDC port, flows through the inductor L1, capacitor C1, capacitor C2, power chip U1, capacitor C3, resistor R1, resistor R3, capacitor C4, inductor L2, diode D3, diode D2, capacitor C6 and resistor R8, and a 12V voltage signal can be obtained.

[0124] In this embodiment, the second power supply circuit (b) is used to further step down the voltage signal output by the first power supply circuit (a). Figure 7As shown, the second power supply circuit (b) includes a power supply chip U2, a capacitor C8 and a capacitor C7, wherein the capacitor C8 is connected to the input interface (IN) of the power supply chip U2, and the capacitor C7 is connected to the output interface (OUT) of the power supply chip U2. The voltage signal output by the first power supply circuit (a) enters the power supply chip U2 through the input interface of the power supply chip U2, and after being processed by the power supply chip U2, a 5V voltage signal can be output from the output interface of the power supply chip U2.

[0125] After obtaining the 12V and 5V voltage signals, power can be supplied to the driving module 30 to ensure the operation of the driving module 30 .

[0126] Since most of the current frame circuit breakers' micro switches are used to directly connect and disconnect the motor, the damage to the micro switch is relatively large. If the micro switch contacts stick, the motor will not be able to be turned off, and eventually the motor will burn out or the energy storage mechanism will be damaged. In order to improve the safety of the device and avoid device burning, in this embodiment, please refer to Figure 8 The driving module 30 includes a triggering submodule 31 and a driving submodule 32 .

[0127] The trigger submodules 31 are respectively connected to the energy storage mechanism of the frame circuit breaker and electrically connected to the control module 20 .

[0128] The driving submodule 32 is electrically connected to the control module 20 .

[0129] The trigger submodule 31 is used to receive the energy storage signal from the energy storage mechanism and send the energy storage signal to the control module 20 .

[0130] The control module 20 is used to control the operation of the driving submodule 32 according to the access status and the energy storage signal.

[0131] The trigger submodule 31 is connected to the energy storage structure of the frame circuit breaker. When the energy storage mechanism of the frame circuit breaker needs to start storing energy or when energy storage is completed, it will send an energy storage signal. After receiving the energy storage signal, the trigger submodule 31 can send the energy storage signal to the control module 20. After receiving the energy storage signal, the control module 20 can control the operation of the drive submodule based on the load resistance, the connection status of the input power supply, and the energy storage signal.

[0132] In this embodiment, after receiving the energy storage signal, the control module 20 controls the driver submodule 32 to not operate if it first determines that the connection status between the load resistor and the input power supply is open or short-circuited. If it first determines that the connection status between the load resistor and the input power supply is normal, the control module 20 controls the operation of the driver submodule 32 based on the type of energy storage signal. For example, when the energy storage signal is a signal indicating the start of energy storage, the control module 20 controls the driver submodule 32 to operate to perform energy storage. If the energy storage signal is a signal indicating the completion of energy storage, the control module controls the driver submodule 32 to stop operating.

[0133] In this embodiment, the control module 20 controls the operation of the driving submodule 32 and stores energy, and also monitors the energy storage time. When the energy storage time exceeds the set value and the energy storage completion signal sent by the triggering submodule 31 is not received, the driving submodule 32 will be controlled to stop running, and a fault signal will be sent to alarm. In this way, the driving submodule 32 can be prevented from burning due to long-term operation.

[0134] The frame circuit breaker energy storage control device provided in this embodiment controls the operation of the driver submodule through the control module, thereby avoiding direct connection between the trigger submodule and the driver submodule, reducing damage to the trigger submodule. At the same time, by monitoring the energy storage time and controlling the driver submodule to stop operating when the energy storage time exceeds a set value, the driver submodule can be effectively prevented from burning out due to long-term operation.

[0135] In order to realize the energy storage control of the frame circuit breaker and send different energy storage signals, please refer to Figure 9 The trigger submodule provided in this embodiment includes a control switch S1, a first signal output channel, and a second signal output channel.

[0136] The first signal output channel is electrically connected to the first contact of the control switch S1 and the control module 20 respectively.

[0137] The second signal output channel is electrically connected to the second contact of the control switch S1 and the control module 20 respectively.

[0138] The first signal output channel is used to send an energy storage signal indicating the start of energy storage to the control module 20 when the first contact of the control switch S1 is closed.

[0139] The second signal output channel is used to send an energy storage completion signal to the control module 20 when the second contact of the control switch S1 is closed.

[0140] like Figure 9As shown, the first signal output channel can be composed of a resistor R17 and an optocoupler U3, and the second signal output channel can be composed of a resistor R21 and an optocoupler U5. One end of the resistor R17 is connected to the first contact 3 of the control switch S1, and the other end is connected to the optocoupler U3. The output end of the optocoupler U3 is connected to the Status ON interface of the control module. One end of the resistor R21 is connected to the second contact 1 of the control switch S1, and the other end is connected to the optocoupler U5. The output end of the optocoupler U5 is connected to the Status NC interface of the control module.

[0141] Among them, the control switch S1 is a microswitch installed on the energy storage mechanism, the first contact 3 is the position where energy storage starts, and the second contact 1 is the position where energy storage is completed. When energy storage is needed, the energy storage mechanism triggers the first contact 3 of the control switch S1 to close, the second contact 1 to disconnect, and the first signal output channel to connect. The energy storage start signal is sent to the control module 20 via the Status ON interface. After receiving the energy storage start signal, if the connection status of the load resistor R2 and the input power supply is normal, the control module 20 controls the drive submodule 32 to operate and perform energy storage. When energy storage is completed, the energy storage mechanism triggers the second contact 1 of the control switch S1 to close, the first contact 3 to disconnect, the second signal output channel to connect, and the first signal output channel to disconnect. The second signal output channel sends the energy storage completion signal to the control module 20 via the Status NC interface. After receiving the energy storage completion signal, the control module 20 controls the drive submodule 32 to stop operating.

[0142] It is understandable that in this embodiment, the trigger submodule 31 may also include some conventional peripheral related devices, such as Figure 9 The resistors R18 and R23 in the circuit, the working principles and functions of the above components can be found in existing technical information and will not be elaborated here.

[0143] In order to facilitate the control of the energy storage process of the frame circuit breaker, in this embodiment, the driving submodule includes a speed control module and a power module.

[0144] The power module is electrically connected to the control module.

[0145] The speed control module is electrically connected to the control module and the power module respectively.

[0146] The power module is used to receive the control signal from the control module and execute the operation action or stop the operation action according to the control signal; wherein, the control module is used to send the control signal to the power module according to the access status and the energy storage signal.

[0147] The speed control module is used to receive the speed signal from the control module and control the speed of the power module according to the speed signal.

[0148] Please refer to Figure 10 , Figure 10 The figure is a schematic diagram of a circuit structure of a driving submodule. Among them, the power module B1 can be a motor, and the speed control module U4 can be a control chip, such as Figure 10 As shown, one end of the power module B1 is connected to the HVDC port, and the other end is connected to the third switch tube Q3 and the MOTO_AD interface of the control module. The input end (IN+) of the speed control module U4 is connected to the PWM interface of the control module, and the output end (OUT) is connected to the power module B1 after being connected to the resistor R19 and the third switch tube Q3.

[0149] When the control module needs to control the power module B1 to run or stop running, it can send a control signal to the power module B1 through the MOTO_AD interface, and the power module B1 will respond to the control signal after receiving the control signal and perform the running action or the stopping action. For example, after the control module receives the energy storage start signal sent by the trigger submodule, if the connection status of the load resistor R2 and the input power supply is normally connected, the control module sends a control signal to the power module B1 through the MOTO_AD interface according to the energy storage start signal, and the power module B1 performs the running action after receiving the control signal. For another example, after the control module receives the energy storage completion signal sent by the trigger submodule, if the connection status of the load resistor R2 and the input power supply is normally connected, the control module sends a control signal to the power module B1 through the MOTO_AD interface according to the energy storage completion signal, and the power module B1 performs the stopping action after receiving the control signal.

[0150] When the control module needs to control the speed of the power module B1, it can send a speed signal to the speed control module U4 through the PWM interface. After receiving the speed signal, the speed control module U4 controls the speed of the power module B1 according to the speed signal.

[0151] It is understandable that in this embodiment, the driver submodule may further include some conventional peripheral related devices, such as Figure 10 The resistor R22, resistor R24, resistor R20, diode D8, capacitor C18, capacitor C19, etc., the working principles and functions of the above components can be referred to existing technical information, and will not be elaborated here.

Based on the voltage of the detection resistor, the connection status of the load resistor and the input power supply is determined. In this way, it can effectively identify whether there is an input wiring error. When a wiring error occurs, the drive module is controlled not to operate, thereby effectively avoiding damage to the drive module caused by the wiring error. The frame circuit breaker processing device provided in this embodiment controls the operation of the drive submodule through the control module, which can avoid direct connection between the trigger submodule and the drive submodule, that is, avoid direct connection between the switch and the motor, reducing damage to the trigger submodule (switch). At the same time, by monitoring the energy storage time, when the energy storage time exceeds the set value, the drive submodule is controlled to stop operation, which can effectively avoid burning of the drive submodule due to long-term operation.

The input detection module is configured to send a detection signal to the control module, which, based on the detection signal, determines the connection status between the input detection module and the input power supply and controls the operation of the drive module accordingly. This allows the drive module to be controlled to cease operation when an error occurs in the connection status, effectively avoiding damage to the drive module due to wiring errors, effectively protecting the drive module, and improving the safety of the frame circuit breaker.
