At present, most of the existing frame circuit breakers realize energy storage by controlling the starting and stopping of a motor through a microswitch; when the micro switch is in the energy storage position, the micro switch is closed, the power supply of the motor is switched on, the energy storage mechanism of the circuit breaker stores energy, and when the energy storage is finished, the micro switch is switched off, and the motor stops. This mode is with micro-gap switch direct switch-on and disconnection motor, and is great to the micro-gap switch damage, and the trouble often is the contact adhesion, and the motor can't be closed so in case the adhesion, finally can lead to the motor to burn out or energy storage mechanism to destroy.

The frame circuit breaker processing apparatus that this embodiment provided carries out the collection of signal and controls each module through its I/O interface through control module, has realized the energy storage to the frame circuit breaker and under the condition of input terminal wrong line, the protection to each module.

Referring to fig. 3, in order to detect the connection status of the input detection module and the input power, in the present embodiment, the input detection module 10 includes a load resistor R2 and a detection resistor R5.

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.

The control module 20 is configured to obtain a voltage of the detection resistor R5, and determine an access state of the load resistor R2 and the input power according to the voltage of the detection resistor R5.

As shown in fig. 3, the input power source 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.

In this embodiment, the load resistor R2 may be an indicator light, and when the load resistor R2 is normally connected, one end of the load resistor R2 is connected to the zero line of the input power, 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 to both ends of the input power.

When the user misconnects the wiring of the load resistor R2, which causes the short circuit of the load resistor R2, the detection resistor R5 is directly connected to the input power, which can be equivalent to the detection resistor R5 connected in parallel to the two ends of the input power, and the voltage of the detection resistor R5 is higher because there is no voltage division of the load resistor R2.

If the load resistor R2 is not connected, i.e. the load resistor R2 is open-circuited to the input power, no current flows into the detection resistor R5, and the detection resistor R5 has no voltage value.

If the load resistor R2 is normally connected, the power current of the input power flows into the detection resistor R5 from the load resistor R2, and flows back to the input power through the detection resistor R5, which can be equivalent to that the detection resistor R5 is connected in series with the load resistor R2 and then connected in parallel to the two ends of the input power, and the voltage of the detection resistor R5 is reduced due to the voltage division of the load resistor R2.

Therefore, in the embodiment, the voltage of the detection resistor R5 is obtained through the P _ AD interface of the control module, and the connection state of the load resistor R2 and the input power source can be determined according to the voltage of the detection resistor R5.

In an optional embodiment, in this embodiment, when the load resistor R2 is normally connected, the voltage of the detection resistor R5 is detected to obtain the voltage value of the detection resistor R5 when the load resistor R2 is normally connected, then a voltage range is set according to the voltage value of the detection resistor R5 when the load resistor R2 is normally connected, and subsequently if the voltage value of the detection resistor R5 is detected to be higher than the voltage range, it may be determined that the connection state of the load resistor R2 and the input power supply is short-circuited, and if the voltage value of the detection resistor R5 is detected to be in the voltage range, it is determined that the connection state of the load resistor R2 and the input power supply is normally connected, and correspondingly, if the voltage value of the detection resistor R5 is detected to be 0, it is determined that the connection state of the load resistor R2 and the input power supply is open-circuited.

In an optional embodiment, when the voltage range is set according to the voltage value of the detection resistor R5 when the load resistor R2 is normally connected, the voltage value of the detection resistor R5 may be measured multiple times after the load resistor R2 is normally connected, the voltage range is set according to the maximum value and the minimum value of the voltage value of the detection resistor R5 measured multiple times, or the voltage range may be set according to the average value of the voltage values of the detection resistor R5 measured multiple times, the standard deviation of the average value ± a set multiple, the set multiple may be set according to actual needs, and this embodiment is not particularly limited.

In this embodiment, after the control module 20 obtains the voltage of the detection resistor R5 through the P _ AD interface, it is determined according to the voltage of the detection resistor R5 that the connection state of the load resistor R2 and the input power is a short circuit state or an open circuit state, it is determined that a wiring error exists, then the drive module 30 is controlled not to operate, and when it is determined according to the voltage of the detection resistor R5 that the connection state of the load resistor R2 and the input power is a normal connection state, it is determined that no wiring error exists, and then the drive module 30 is controlled to operate normally, so that it is avoided that the drive module 30 operates under the condition of a wiring error, and the drive module 30 is damaged, and meanwhile, when the wiring is normal, the normal operation of the drive module 30 is ensured, so as to realize energy storage of the frame circuit breaker.

The frame circuit breaker energy storage control device that this embodiment provided, through setting up input detection module, set up detection resistance in input detection module, through the voltage that acquires detection resistance, according to detection resistance's voltage, confirm the access state of load resistance and input power, so, can effectively discern whether there is the condition of input wiring mistake, and when the wiring mistake appears, control drive module does not operate, and then effectively avoided because of the damage of the drive module that the wiring mistake caused.

In order to protect the circuit and facilitate the connection of the circuit, in this embodiment, as shown in fig. 3, the input detection module 10 may further include a connection terminal P1, a diode D4, a protection resistor R9, a rectifier bridge D1, and other circuit devices.

The No. 1 terminal of the wiring terminal is connected with a live wire of an input power supply, the No. 3 terminal and the No. 5 terminal are connected with a zero wire of the input power supply, the No. 2 terminal and the No. 4 terminal are connected with a rectifier bridge D1, the No. 6 terminal is connected with one end of a diode D4, the other end of the diode D4 is connected with one end of a protection resistor R9, the other end of the protection resistor R9 is connected with one end of a detection resistor R5, and the other end of the detection resistor R5 is connected with a rectifier bridge D1. When the load resistor R2 is normally connected, one end of the load resistor R2 is connected with a zero line of an input power supply, the other end of the load resistor R2 is connected with a No. 5 terminal of a connecting terminal P1, and the load resistor R2, the connecting terminal P1, the diode D4, the protective resistor R9, the detection resistor R5, the rectifier bridge D1 and the input power supply can form a series circuit, at the moment, the series circuit has the voltage division of the load resistor R2, and the voltage value of the detection resistor R5 is lower; when the load resistor R2 is in short circuit, the No. 5 terminal of the connecting terminal P1 is directly connected to the zero line of the input power supply, the connecting terminal P1, the diode D4, the protective resistor R9, the detection resistor R5, the rectifier bridge D1 and the input power supply form a series circuit, at the moment, the series circuit has no voltage division effect of the load resistor R2, and the voltage value of the detection resistor R5 is higher; when the load resistor R2 is open-circuit, no current passes through, the load resistor R2, the connecting terminal P1, the diode D4, the protection resistor R9, the detection resistor R5, the rectifier bridge D1 and the input power supply do not form a loop, and no voltage exists in the detection resistor R5.

The frame circuit breaker energy storage control device that this embodiment provided, through the voltage of gathering detection resistance R5, according to detection resistance R5's voltage, detect the access state of load and input power, can effectively discern the wrong fault circuit of wiring and the correct normal circuit of wiring, and then when controlling drive module operation according to the access state, can effectively avoid the damage of the drive module that consequently wrong caused of wiring.

Since the control module 20 only needs to detect the connection condition before performing the energy storage operation in practical applications, please continue to refer to fig. 3 for convenience of detection, in this embodiment, the input detection module further includes a first switch Q1.

The first switch Q1 is connected in series with the detection resistor R5, and is electrically connected to the control module 20 and the load resistor R2 after being connected in series.

The control module 20 is configured to control a conducting state of the first switch Q1, obtain a voltage of the detection resistor R5 after the first switch Q1 is turned on, and determine an access state of the load resistor R2 and the input power according to the voltage of the detection resistor R5.

The first switch tube Q1 may be a field effect transistor (MOS tube), a triode, or other switch tubes. Optionally, in this embodiment, the first switch is a MOS transistor, a gate of the first switch is connected to the Dr _ P port of the control module 20, a drain of the first switch is connected to the protection resistor R9, and a source of the first switch is connected to the detection resistor R5.

When the frame circuit breaker needs to store energy, the control module sends a signal to the first switch tube Q1 to enable the first switch tube Q1 to be switched on, and after the first switch tube Q1 is switched on, whether the load resistor R2 is normally switched on or not can be determined by collecting the voltage of the detection resistor R5 and according to the voltage of the detection resistor R5.

When a user is misconnected or a load is in short circuit, when the No. 5 terminal of the wiring terminal P1 is directly in short circuit with the zero line of an input power supply, the power supply current flows back to the power supply through the diode D4, the protection resistor R9, the first switching tube Q1, the detection resistor R5, the rectifier bridge D1 and the No. 2 terminal and the No. 1 terminal of the wiring terminal P1. Because the voltage drop of the diode D4, the first switching tube Q1 and the rectifier bridge D1 is very low and negligible, the protection resistor R9 and the detection resistor R5 can be equivalently connected in series and then connected in parallel at two ends of the power supply, the voltage value of the detection resistor R5 is read by a P _ AD port of the control module, and the voltage value of the detection resistor R5 is higher because the load resistor R2 does not have the function at this time.

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

If the load resistor R2 is normally connected to the input power source, the power current of the input power source flows back to the input power source through the load resistor R2, the terminals No. 5 and No. 6 of the terminal P1, the diode D4, the protection resistor R9, the first switch tube Q1, the detection resistor R5, the rectifier bridge D1, the terminal No. 2 of the terminal P1, and the terminal No. 1, and the voltage drops of the diode D4, the first switch tube Q1, and the rectifier bridge D1 are negligible, so that the detection resistor R5, the protection resistor R9, and the load resistor R2 are equivalently connected in series and then connected in parallel to both ends of the input power source. Due to the voltage dividing function of the load resistor R2, the voltage of the detection resistor R5 is lower than the voltage of the load resistor R2 during short circuit and higher than the voltage of the load resistor R2 during open circuit.

After the control module obtains the voltage value of the detection resistor R5 through the P _ AD interface, whether the voltage value of the detection resistor R5 is within the set voltage range can be judged. If the voltage value of the detection resistor R5 is higher than the set voltage range, the load resistor R2 is judged to be short-circuited, and the driving module 30 is controlled not to operate; if the voltage value of the detection resistor R5 is zero, it is determined that the load resistor R2 and the input power supply are open-circuited, and the driving module 30 is controlled not to operate; if the voltage value of the detection resistor R5 is within the set voltage range, it is determined that the load resistor R2 and the input power supply are normally connected, and the driving module 30 is controlled to operate.

In this embodiment, after detecting the connection state between the load resistor R2 and the input power, the first switch Q1 may be turned off, and if the connection state between the load resistor R2 and the input power is determined to be normal, the driving module 30 may be controlled to operate, and if the connection state between the load resistor R2 and the input power is determined to be short-circuited or open-circuited, the driving module 30 may be controlled not to operate, and the user may wait for the connection to be reconnected. It can be understood that, after the user completes the wiring again, before storing energy, the first switching tube Q1 still needs to be turned on to detect the access state, and only when the detection is normal, the driving module 30 is controlled to operate, so that the product failure caused by misconnection and load short circuit can be prevented.

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

The second switching tube Q2 is electrically connected to the control module after being connected in series with the relay K1, and the relay K1 is electrically connected to the load resistor R2 after being connected in series with the second switching tube Q2.

The control module 20 is configured to control a conducting state of the second switch tube Q2 according to an access state of the load resistor R2 and the input power source, and control an open/close state of the relay K1 according to the conducting state of the second switch tube Q2.
