Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage electrical switches, and in particular to a circuit breaker control device and a circuit breaker. Background Art

[0002] With the rapid development of economy and the rapid improvement of people's living standards, there is a higher demand for household electricity safety. Miniature circuit breakers can be installed in terminal distribution lines due to their small size. At the same time, they can also connect, carry and disconnect currents under normal or abnormal circuit conditions, forming effective protection for lines and electrical equipment. With the in-depth study of circuit breakers, the technology of remote control of circuit breaker opening and closing has gradually matured.

[0003] When the existing remote circuit breaker realizes remote action, it needs to connect the power line and the motor to provide power for it. In order to realize remote action, it is also necessary to set a control line to control the rotation of the motor to drive the operating mechanism to complete the action of the circuit breaker. However, since the power line and the control line are laid separately, the internal wiring of the entire circuit breaker is complicated. Summary of the invention

[0004] The object of the present invention is to provide a circuit breaker control device and a circuit breaker to solve the problem of complex wiring of existing remote circuit breakers in view of the above-mentioned deficiencies in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the embodiment of the present invention is as follows:

[0006] According to one aspect of an embodiment of the present invention, a circuit breaker control device is provided, comprising: a first terminal, a second terminal, a travel switch, a first switching switch, a second switching switch and an action component; the first terminal is connected to the travel switch, the normally closed contact of the travel switch is connected to the normally closed contact of the first switching switch, the first switching switch and the second switching switch are respectively connected to the action component, and the normally closed contact of the second switching switch is connected to the second terminal; the normally open contact of the travel switch is connected to the normally open contact of the second switching switch, and the normally open contact of the first switching switch is connected to the second terminal, so as to control the action component to keep moving in the same direction when the first terminal and the second terminal receive positive and negative electrical signals or negative and positive electrical signals.

[0007] Optionally, the first switching switch and the second switching switch form a linkage switch.

[0008] Optionally, the linkage switch is a polarity trigger relay.

[0009] Optionally, it also includes a diode; the linkage switch is a non-polarity trigger relay; the non-polarity trigger relay is connected in series with the diode.

[0010] Optionally, the first switching switch is a first relay; and the second switching switch is a second relay.

[0011] Optionally, a master control switch is provided between the second terminal and the travel switch.

[0012] Optionally, the action component is connected to a travel switch to switch the on / off state of the travel switch when the action component is in an open or closed state.

[0013] Optionally, the action component includes a rotary drive and an operating mechanism transmission-connected to the rotary output end of the rotary drive; the first switching switch and the second switching switch are respectively connected to the rotary drive, and are used to drive the operating mechanism to be in an open or closed state when the rotary drive rotates.

[0014] Optionally, the operating mechanism engages and transmits the rotation output end of the rotary driver.

[0015] Another aspect of the embodiments of the present invention provides a circuit breaker, comprising any one of the above-mentioned circuit breaker control devices.

[0016] The beneficial effects of the present invention include:

[0017] The present invention provides a circuit breaker control device, the whole circuit breaker control device includes two terminals, namely a first terminal and a second terminal, the two terminals can be connected to an external control system, so as to receive positive and negative electrical signals or negative and positive electrical signals input by the control system under different circumstances. Thereafter, the first terminal is connected to a travel switch, the normally closed contact of the travel switch is connected to the normally closed contact of the first switching switch, the first switching switch and the second switching switch are respectively connected to an action component, the normally closed contact of the second switching switch is connected to the second terminal; the normally open contact of the travel switch is connected to the normally open contact of the second switching switch, and the normally open contact of the first switching switch is connected to the second terminal. Therefore, after the first terminal and the second terminal receive opposite positive and negative electrical signals in different time periods, the contact connection positions of the travel switch, the first switching switch and the second switching switch are switched accordingly, so that the action component always keeps moving in the same direction when it is turned on, that is, always keeps moving in one direction. Thereby, the action component in the circuit breaker is actuated. By only providing the first terminal and the second terminal, it is realized that while the action component is powered, the action of the action component is controlled by the connected positive and negative electrical signals. That is, the power supply circuit and the control circuit circuit in the existing circuit breaker are integrated, so as to reduce the number of circuit layouts of the circuit breaker, simplify the circuit, and reduce the difficulty of circuit layout.

The number of lines inside the circuit breaker is effectively reduced, the difficulty of line layout in the circuit breaker is reduced, and it is conducive to the miniaturization of the circuit breaker.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. It should be noted that, in the absence of conflict, the various features in the embodiments of the present invention can be combined with each other, and the combined embodiments are still within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] With the improvement of the safety level of electricity use, the use of low-voltage circuit breakers is becoming more and more common. When the existing remote circuit breaker realizes remote action, it first needs a power cord to provide basic power supply for the motor inside it. In addition, in order to realize remote control, it is also necessary to connect the drive motor to the control circuit separately, so that the motor can realize the corresponding instructions, such as forward or reverse rotation, through the control instructions of the control circuit. However, since the power supply line and the control circuit line need to be set separately, the connection lines inside the circuit breaker are relatively complicated. Based on this, the present application provides a circuit breaker control device and a circuit breaker, which can provide power to the motor using the first terminal and the second terminal, and can also provide control instructions for it, so that the motor always rotates in the same direction, thereby simplifying the wiring inside the circuit breaker and improving the accuracy of control.

[0033] According to one aspect of an embodiment of the present invention, a circuit breaker control device is provided, comprising: a first terminal P1, a second terminal P2, a travel switch S1, a first switching switch, a second switching switch and an action component; the first terminal P1 is connected to the travel switch S1, the normally closed contact of the travel switch S1 is connected to the normally closed contact of the first switching switch, the first switching switch and the second switching switch are respectively connected to the action component, and the normally closed contact of the second switching switch is connected to the second terminal P2; the normally open contact of the travel switch S1 is connected to the normally open contact of the second switching switch, and the normally open contact of the first switching switch is connected to the second terminal P2, so as to control the action component to keep moving in the same direction when the first terminal P1 and the second terminal P2 receive positive and negative electrical signals or negative and positive electrical signals.

[0034] For example, the entire circuit breaker control device includes two terminals, namely the first terminal P1 and the second terminal P2, and the two terminals can be connected to the external control system, so as to receive the positive and negative electrical signals or the negative and positive electrical signals input by the control system under different circumstances. Thereafter, the first terminal P1 is connected to the travel switch S1, the normally closed contact of the travel switch S1 is connected to the normally closed contact of the first switching switch, the first switching switch and the second switching switch are respectively connected to the action component, and the normally closed contact of the second switching switch is connected to the second terminal P2; the normally open contact of the travel switch S1 is connected to the normally open contact of the second switching switch, and the normally open contact of the first switching switch is connected to the second terminal P2. At this time, when the external control system inputs a positive electrical signal to the first terminal P1 and a negative electrical signal to the second terminal P2, the current flows from the first terminal P1 to the normally closed contact of the travel switch S1 to the normally closed contact of the first switching switch to the action component to the normally closed contact of the second switching switch to the second terminal P2.

[0035] Before the external control system inputs the positive electric signal to the second terminal P2 and the negative electric signal to the first terminal P1, the control (which can be a separate control or a control circuit set in parallel with the action component for synchronous control) switches the travel switch S1, the first switch and the second switch to the normally open contact, that is, the second terminal P2 is connected through the normally open contact of the first switch, and after the action component, the normally open contact of the second switch is connected to the first terminal P1 through the normally open contact of the travel switch S1. At this time, the current flows from the second terminal P2 to the normally open contact of the first switch to the action component to the normally open contact of the second switch to the normally open contact of the travel switch S1 to the first terminal P1. Therefore, after the first terminal P1 and the second terminal P2 receive opposite positive and negative electric signals in different time periods, the contact connection positions of the travel switch S1, the first switch and the second switch are switched accordingly, so that the action component always keeps moving in the same direction when it is turned on, that is, always keeps moving in one direction. It should be noted that the action components in the present application maintain the same direction of movement, which means that when two different electrical signals are input to the action components, the corresponding movement directions are the same direction.

[0036] For example: when the input positive and negative electrical signals are positive and negative voltages, such as Figure 1 As shown, when contacts 3 and 5 of the travel switch S1 are connected, contacts 7 and 8 of the first switching switch are connected, and contacts 9 and 11 of the second switching switch are connected, the external control system inputs a positive voltage to the first terminal P1, and a negative voltage to the second terminal P2, the current returns to the second terminal P2 through the first terminal P1, contacts 3 and 5 of the travel switch S1, contacts 7 and 8 of the first switching switch, the action component, and contacts 9 and 11 of the second switching switch, thereby forming a loop connected to the entire circuit. At this time, the corresponding movement direction of the action component is Figure 1 The direction indicated by the arrow in the middle (which is only a schematic direction and does not represent the actual movement direction of the action component) means that when the current flows through the action component, its flow direction is from the first switching switch to the second switching switch.

[0037] like Figure 2 As shown, the connection state of the travel switch S1, the first switch and the second switch is switched, so that the 3rd and 4th contacts of the travel switch S1 are connected, the 6th and 8th contacts of the first switch are connected, and the 9th and 10th contacts of the second switch are connected. At this time, when the external control system inputs a negative voltage to the first terminal P1 and a positive voltage to the second terminal P2, the current returns to the first terminal P1 through the second terminal P2, the 6th and 8th contacts of the first switch, the action component, the 9th and 10th contacts of the second switch, and the 4th and 3rd contacts of the travel switch S1, thereby forming a loop for the entire circuit connection. At this time, the corresponding movement direction of the action component is Figure 2The direction indicated by the arrow in the middle (only a schematic direction, not representing the actual movement direction of the action component), that is, when the current flows through the action component, its flow direction is still from the first switching switch to the second switching switch. Therefore, when opposite positive and negative electrical signals are respectively input in different time periods, the action component can always keep moving in one direction, so that the action component in the circuit breaker is actuated. By only providing the first terminal and the second terminal, it is possible to control the action of the action component by using the connected positive and negative electrical signals while powering the action component. That is, the power supply line and the control circuit line in the existing circuit breaker are integrated, thereby reducing the number of line layouts of the circuit breaker, simplifying the circuit, and reducing the difficulty of circuit layout.

[0038] Optionally, the first switching switch and the second switching switch form a linkage switch.

[0039] For example, Figure 1 As shown, the first switch and the second switch can form a linkage switch, that is, the switching actions of the two switches are performed synchronously. Therefore, when the different contacts of the first switch and the second switch are switched, the actions of the two switches are consistent. This avoids the cumbersome operation of switching separately, and at the same time, improves the stability of switching.

[0040] Optionally, the linkage switch is a polarity trigger relay K2.

[0041] For example, Figure 3 , 4 As shown, the linkage switch can be a polar trigger relay K2. Correspondingly, the contacts 6, 7, 8 of the first switch and the contacts 9, 10, 11 of the second switch in the linkage switch are the switch contacts on the circuits on both sides of the action component in the polar trigger relay K2. The control circuit of the polar trigger relay K2 can be set separately or incorporated into the control circuit of the action component as described below.

[0042] Correspondingly, such as Figure 3 , 4 As shown, the control circuit of the polar trigger relay K2 can be incorporated into the control circuit of the aforementioned action component. At this time, the electromagnetic part in the polar trigger relay K2 is connected to the first terminal P1 and the second terminal P2 respectively, that is, a loop is formed by the first terminal P1, the electromagnetic part in the polar trigger relay K2 and the second terminal P2. Since the permanent magnet in the polar trigger relay K2 is always magnetic, it has a bistable characteristic, that is, the open state and the closed state can maintain a steady state without external factors. Therefore, the integration and automation of the control can be effectively improved, and the complexity of the circuit layout can be reduced. At the same time, the switching contacts and the action components of the first switching switch and the second switching switch need to act, and the consistency and synchronization of the two are also required.

[0043] For example: Figure 3 As shown, when the first terminal P1 is connected to a positive voltage and the second terminal P2 is connected to a negative voltage, the current is divided into two parts, one part flows into the electromagnetic part of the polar trigger relay K2 through the first terminal P1 and flows back to the second terminal P2. The other part returns to the second terminal P2 through the contacts 3 and 5 of the travel switch S1, the contacts 7 and 8 of the contact part of the polar trigger relay K2, the action component, and the contacts 9 and 11 of the contact part of the polar trigger relay K2. It should be noted that after the current flows through the electromagnetic part of the polar trigger relay K2 and the second terminal P2 to form a loop, if at this time, the contacts 7 and 8 and the contacts 9 and 11 of the polar trigger relay K2 are already connected, it will not act and continue to remain connected. If at this time, the contacts 6 and 8 and the contacts 9 and 10 of the polar trigger relay K2 are connected, it will switch the state so that the contacts 7 and 8 and the contacts 9 and 11 are connected.

[0044] like Figure 4 As shown, when the first terminal P1 is connected to a negative voltage and the second terminal P2 is connected to a positive voltage, the current is also divided into two parts. One part flows into the electromagnetic part of the polar trigger relay K2 through the second terminal P2 and flows back to the first terminal P1. The other part returns to the first terminal P1 through the contacts 6 and 8 of the contact part of the polar trigger relay K2, the action component, the contacts 9 and 10 of the contact part of the polar trigger relay K2, and the contacts 4 and 3 of the travel switch S1. It should also be noted that after the current flows through the electromagnetic part of the polar trigger relay K2 and the first terminal P1 to form a loop, if at this time, the contacts 10 and 9 and the contacts 8 and 6 of the polar trigger relay K2 are already connected, it will not act and continue to remain connected. If at this time, the contacts 11 and 9 and the contacts 8 and 7 of the polar trigger relay K2 are connected, it will switch the state so that the contacts 10 and 9 and the contacts 8 and 6 are connected.

[0045] Optionally, a diode is also included; the linkage switch is a non-polarity trigger relay K1; the non-polarity trigger relay K1 is connected in series with the diode.

[0046] For example, when the linkage switch is a non-polar trigger relay K1, that is, there is no permanent magnetic magnet in the relay, then it can have a separate circuit to control it and switch the contact state. At the same time, it can also be incorporated into the control circuit of the aforementioned action component.

[0047] Correspondingly, such as Figure 1 , 2As shown, the control circuit of the non-polarity trigger relay K1 can be incorporated into the control circuit of the aforementioned action component. At this time, in order to avoid the non-polarity trigger relay K1 being easily disturbed by external factors in a monostable state, resulting in the non-polarity trigger relay K1 causing misoperation when different positive and negative voltages are applied, a unidirectional diode can also be provided. The connection relationship is as follows: the second terminal P2 is connected to the electromagnetic part in the non-polarity trigger relay K1, the electromagnetic part in the non-polarity trigger relay K1 is connected to the diode, and the diode is connected to the first terminal P1, that is, a loop is formed by the second terminal P2, the electromagnetic part in the non-polarity trigger relay K1, the diode and the first terminal P1. By utilizing the unidirectional conductivity of the diode, the current of the misoperation can be cut off, so that when the non-polarity trigger relay K1 does not need to act, it is disconnected by the diode, so that it cannot form a loop. The use of the non-polarity trigger relay K1 can effectively reduce the manufacturing cost of the circuit breaker control device of the present application, and the diode can realize the synchronous action controlled by only the same electrical signal, and can also effectively avoid the misoperation of the non-polarity trigger relay K1.

[0048] For example: Figure 1 As shown in the figure, when the first terminal P1 is connected to a positive voltage and the second terminal P2 is connected to a negative voltage, the current is divided into two parts. One part is cut off when passing through the diode. At this time, the electromagnetic part of the non-polar trigger relay K1 is not energized and the switch remains in the normally closed state. The other part returns to the second terminal P2 through the contacts 3 and 5 of the travel switch S1, the contacts 7 and 8 of the contact part of the non-polar trigger relay K1, the action component, and the contacts 9 and 11 of the contact part of the non-polar trigger relay K1.

[0049] like Figure 2 As shown, when the first terminal P1 is connected to a negative voltage and the second terminal P2 is connected to a positive voltage, the current is also divided into two parts. One part flows into the electromagnetic part of the polarity-free trigger relay K1 through the second terminal P2 and flows back to the first terminal P1 through the diode conduction. At this time, the electromagnetic part of the polarity-free trigger relay K1 is energized, and the control contacts 6 and 8 are connected and the contacts 9 and 10 are connected. The other part returns to the first terminal P1 through the contacts 6 and 8 of the contact part of the polarity-free trigger relay K1, the action component, the contacts 9 and 10 of the contact part of the polarity-free trigger relay K1, and the contacts 4 and 3 of the travel switch S1.

[0050] Optionally, the first switching switch is a first relay; and the second switching switch is a second relay.

[0051] For example, when the first switching switch and the second switching switch are controlled separately, the first switching switch can be made into a first relay; and the second switching switch can be made into a second relay. That is, a separate control circuit is used to switch the contact positions in the first switching switch and the second switching switch. It should be noted that when the two are controlled separately, mutual interference can be avoided. At the same time, both need to switch states to connect the control circuit of the action component, thereby further improving the safety of the circuit breaker and avoiding the possibility of accidental closing. At the same time, the first relay and the second relay can be both non-polar trigger relays K1 or polar trigger relays K2. In addition, the first relay can be a non-polar trigger relay K1, and the second relay can be a polar trigger relay K2, or vice versa. This application does not limit it.

[0052] Optionally, a master control switch S2 is provided between the second terminal P2 and the travel switch S1.

[0053] For example, in order to further improve the safety of the circuit breaker control device, a master control switch S2 can be provided on the main circuit of the control device. That is, the master control switch S2 is directly connected to the first terminal P1 or the second terminal P2, so that by disconnecting the master control switch S2, the entire circuit breaker control device is disconnected, that is, the action component is disconnected. At this time, the action component cannot continue to move in the same direction under the action of the electrical signal, and the circuit breaker cannot be closed. This avoids the situation where the circuit breaker is in manual mode or automatic mode disconnected, resulting in the remote control of the circuit breaker closing due to information asynchrony or misoperation, thereby creating a safety hazard. For example Figures 1 to 4 As shown, the master control switch S2 is set at a position close to the second terminal P2, and the entire control circuit and the second terminal P2 can be disconnected by turning it off. Figure 5 As shown, the master control switch S2 is arranged above the action component, which can be a Hall switch or a micro switch. Correspondingly, the travel switch S1 can also be a micro switch. This application does not limit it.

[0054] Optionally, the action component is connected to the travel switch S1 to switch the on / off state of the travel switch S1 when the action component is in an open or closed state.

[0055] For example, Figure 5 As shown, the action component and the travel switch S1 can be mechanically connected to establish a feedback system. Figure 3 As shown in FIG. 1 , when the first terminal P1 is connected to a positive voltage and the second terminal P2 is connected to a negative voltage, the current returns to the second terminal P2 via contacts 3 and 5 of the travel switch S1, contacts 7 and 8 of the contact part of the polarity trigger relay K2, the action component, and contacts 9 and 11 of the contact part of the polarity trigger relay K2. At this time, the action component is connected along Figure 3 Move in the direction indicated by the arrow in the figure. At this time, the corresponding Figure 5 The rotary driver M in the actuator is driven by the operating mechanism 100 to realize the opening or closing of the moving and static contacts. At this time, the lever 101 in the operating mechanism 100 will also drive the travel switch S1 to connect the 3rd and 4th contacts of the travel switch S1. At this time, the action component is disconnected and stops moving. Figure 4 As shown, when the first terminal P1 is connected to a negative voltage and the second terminal P2 is connected to a positive voltage, the linkage feedback relationship between the action component and the travel switch S1 is the same, which will not be elaborated here.

[0056] Optionally, the action component includes a rotary driver M and an operating mechanism 100 that is transmission-connected to the rotary output end of the rotary driver M; the first switching switch and the second switching switch are respectively connected to the rotary driver M, and are used to drive the operating mechanism 100 to be in an open or closed state when the rotary driver M rotates.

[0057] For example, Figure 5 As shown, the action assembly includes a rotary drive M and an operating mechanism 100. The rotary drive M is directly connected to Figures 1 to 4 In the control circuit, the rotary driver M is controlled to rotate in the same direction by the on-off correspondence of the control circuit. When the rotary driver M is powered on and rotates, it drives the operating mechanism 100 to move, so that the moving contact and the static contact in the operating mechanism 100 contact to complete the closing of the circuit breaker, or the moving contact and the static contact in the operating mechanism 100 separate to complete the opening of the circuit breaker.

[0058] Optionally, the operating mechanism 100 is meshed with the rotary output end of the rotary driver M for transmission.

[0059] For example, the operating mechanism 100 is meshed with the rotating output end of the rotating driver M, that is, the two are linked by gear transmission. Figure 5 As shown, a helical tooth is provided at the rotation output end of the rotary driver M, and a rotatable gear is provided at one end of the operating mechanism 100 accordingly, so that the teeth on the gear and the helical teeth on the rotation output end cooperate with each other. When the rotary driver M rotates, the gear can be driven to rotate, thereby continuously transmitting to the moving contact, thereby driving the moving contact to move. Through the transmission mode of worm gear, the stability and accuracy of the transmission can be effectively improved.

[0060] Another aspect of the embodiments of the present invention provides a circuit breaker, comprising any one of the above-mentioned circuit breaker control devices.

[0061] For example, Figure 5As shown, the above-mentioned circuit breaker control device is applied to the circuit breaker, and the contact connection positions of the travel switch S1, the first switch and the second switch can be switched accordingly, so that the action component always keeps moving in the same direction when it is turned on, so that after the circuit breaker is switched from closing to opening, when it needs to be closed again, the action component can still move in the same direction to complete the reclosing. The number of lines inside the circuit breaker is effectively reduced, the difficulty of line layout in the circuit breaker is reduced, and it is conducive to the miniaturization of the circuit breaker.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
