Background
Conventional circuit breakers, also known as fuseless opens, usually integrate circuits in the same space in the same circuit, so as to form a short-circuit protection function when the power supply is overloaded. The action principle is usually to use the physical thermal sensing method to form trip circuit and generate protection function. Generally, the breaker is classified by a rated current amount, and the breaker is operated only when a current larger than the rated current flows. When the overload current is larger, the speed of tripping the open circuit is shorter, otherwise, the time required for tripping the open circuit is longer. For example, when the rated current of the conventional circuit breaker is 20 amperes, a current greater than 20 amperes must flow, and the circuit breaker operates to automatically trip to form an open circuit. If all plugs in a room are connected by the same shunt switch, it is theoretically safe and the non-fuse switch will not trip if the rated capacity of the non-fuse switch in the shunt is 20 amperes and the total power consumption of the electrical equipment used in all plugs is 19 amperes. The term "trip" refers to a state in which a non-fuse switch automatically trips from "card" to "OFF". If the total power consumption is 21 amperes, the setting of the fuse-free switch is determined according to the actual situation at that time, so that some tolerance exists sometimes, certainly, the fuse-free switch cannot jump off, the rated capacity is not exceeded, the time is short, and the fuse-free switch cannot jump off within only a few minutes, so that the link of safe power utilization is uncertain. But if the load is 30 amps or even higher, normally a non-fused switch will trip over the load, but usually not in a few seconds. Even compared with the rated 20 ampere capacity, the fuse-free switch cannot be tripped immediately in a few seconds, and in the few seconds without tripping, because the passing current is very large, the circuit is continuously overloaded, the temperature of the electric appliances, electric wires and the like is raised to a possible melting or even burning state, and a fire alarm disaster is formed. In addition, the conventional non-fuse switch has another function, and can be immediately tripped to generate protection when short circuit and electric leakage are caused by electric appliance failure or improper manual operation. However, when the leakage current is very small, the conventional fuse-free switch does not have the trip phenomenon. However, even if the leakage current is small, a fatal danger often occurs. In the case of a human body, if the current passing through the heart exceeds 100 ma, it may be fatal, and if the current passing through the muscle exceeds 25 ma, involuntary muscle contraction may occur, so that the human body cannot be disconnected from the power supply. In general, a fuseless switch below 30 milliamps should trip well, with a trip time within 0.1 seconds. Of course, the smaller the trip current and the shorter the trip time, the safer the trip is. Obviously, the traditional fuse-free switch cannot generate the function of protecting the human body, and cannot carry out remote monitoring, so as to prevent the occurrence of an electric induction accident.
Summarizing, therefore, the following disadvantages generally occur in the conventional circuit breaker: firstly, because the conventional circuit breaker performs trip breaking according to a mode of metal physical thermal induction rising, the conventional circuit breaker cannot trip breaking immediately when the flowing current is equal to or slightly larger than the rated current, and can only wait for a period of time to trip breaking, so that the phenomenon of delaying trip breaking is generated; the trip and open circuit time is too long, the overload protection capability is insufficient, the short circuit protection capability is not satisfactory, and the self-function diagnosis capability is not available, so that the condition cannot be distinguished, and the safety is really considered. And secondly, the circuit control of the switch can be only carried out on the electric appliances or energy consumption facilities of the same category, other technologies and functions except for electric power are not further extended, and the whole function is weak. Third, the user cannot know the power consumption status in the loop immediately, cannot implement the energy-saving and power-saving measures immediately, and does not have the energy-saving and power-saving functions. And fourthly, the remote monitoring function is not provided, and a user cannot remotely manage and control the system.
The present invention is a novel invention to overcome the disadvantages of the conventional circuit breakers.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
Referring to fig. 1, 2 and 3, fig. 1 is a block diagram of a circuit breaker capable of being remotely controlled according to a first embodiment of the present invention; FIG. 2 is a partial perspective view of a current detection module according to the present invention; fig. 3 is a schematic perspective view of a remotely controllable circuit breaker according to the present invention. The remotely controllable circuit breaker (10) comprising: a fuse-less switch (20), a magnetic latching relay (30), a current detection module (40), a first microswitch (52), a second microswitch (54) and the like. The remotely controllable circuit breaker (10) is disposed within the electrical panel below the main switch, where the branch circuit is used. The fuse-free switch (20) is used as a safety control opening of a loop, circuits in the same space are usually integrated in the same loop, for example, a main bedroom loop, a living room loop, a dining room loop and the like, and the fuse-free switches (20) are respectively arranged for control, when the current exceeds the rated current, the fuse-free switches (20) are tripped, and the loop is cut off, so that the safety of the loop is protected. One end of the fuse-less switch (20) is a power supply terminal (22), and the other end is a load terminal (24). The fuse-free switch (20) should immediately generate the action of breaking when the current exceeds the rated current, but the fuse-free switch (20) often cannot be tripped immediately when the current exceeds the rated current, the circuit breaker can be tripped to actuate after the current accumulation exceeds a certain value of the rated current, the tripping and breaking time is too long, the overload protection capability is insufficient, and thus the risk of generating danger is generated. The load terminal (24) of the fuseless switch (20) is thus electrically connected to one terminal of a magnetic latching relay (30) to assist the fuseless switch (20). When the current flowing through the magnetic latching relay (30) reaches the rated electric quantity, the non-fuse switch (20) is immediately started to cut off the circuit, and the protection of open circuit is generated. The other end of the magnetic latching relay (30) passes through the current detection module (40) through the electric connection wire (32) and penetrates out of the other end of the current detection module (40) to form a power supply end (34), and the power supply end (34) is connected to energy-consuming electrical equipment in a building to provide power. When the electrical connection wire (32) passes through the current detection module (40), the current detection module (40) can detect the magnitude of the current flowing through the magnetic latching relay (30). Referring to fig. 2, the electrical connection line (32) first passes through the current detection module (40), and the current detection module (40) transmits the detected current magnitude signal to a signal output portion (70) through the second and third signal lines (62) and (63). And the current detection device (40) penetrates out to form a power supply end (34) which is then connected to energy-consuming electrical equipment in the building to provide power. A first microswitch (52) is provided on one side of the fuseless switch (20) to sense the state of the fuseless switch (20), and a first signal line (61) extends to the outside of the remotely controllable circuit breaker (10) and is connected to a signal output section (70). A second microswitch (54) is arranged at one side of the magnetic latching relay (30) so as to sense the state of the magnetic latching relay (30), and a sixth signal wire (66) extends to the outside of the remotely controllable breaker (10) and is connected to the signal output part (70). The first micro switch (52) and the second micro switch (54) are connected in series by a connection wire (55). In addition, the current detection module (40) is provided with a second signal line (62) and a third signal line (63), is connected to the signal output part (70), and transmits the detected current amount to the signal output part (70) through the second signal line (62) and the third signal line (63); the magnetic latching relay (30) is provided with a fourth and a fifth signal lines (64) (65) connected to the signal output part (70), and the detected current amount is transmitted to the signal output part (70) through the fourth and the fifth signal lines (64) (65).
Referring to fig. 3, an operating handle (80) is disposed on the front surface of the remotely controllable circuit breaker (10), and the operating handle (80) is used for switching on or off the circuit controlled by the fuseless switch (20). A manual operating lever (90) is arranged at a proper position below the operating handle (80), the manual operating lever (90) is provided with a state indicating cover, and when the internal warning light is changed from a green light to a red light, a user can manually operate the magnetic latching relay (30) through the manual operating lever (90). The first, second, third, fourth, fifth and sixth signal lines (61) (62) (63) (64) (65) (66) pass through the exterior of the remotely controllable circuit breaker (10) and are connected to a signal output section (70). The user uses another operation platform (not shown) to plug in the signal output hole (72) of the signal output part (70), measures the pulse variation of the first and second micro-switches (52, 54) through the coupling current detection module (40) and the magnetic latching relay (30), and uses the measured pulse variation as the input information of the operation platform management device, and manages the relevant signal output by the remotely controlled circuit breaker (10) in real time by matching with the preset programmable operation logic and parameters in the operation platform or the operation logic and parameters set by the management computer through the network. On the other hand, the operation platform can also reversely control the power consumption of the energy consumption equipment connected with the circuit breaker (10) of the invention, set the threshold value for operation, and accurately adjust and control the operation conditions of various energy consumption equipment in the building, thereby achieving the purposes of power consumption management and power consumption safety. In addition, the operating platform can also integrate an intelligent micro-grid and energy consumption equipment controlled by other Programmable Logic Controllers (PLC) interfaces, when the energy consumption equipment of a load end (24) in the same loop with the circuit breaker (10) or the environmental parameters of the service space of the energy consumption equipment are abnormal, the operating platform can inform related personnel in real time through a network and report the operation information of the energy consumption electrical equipment and the environmental parameters of the service space regularly, so that the related personnel can manage and control the circuit breaker (10) and the energy consumption electrical equipment or the service space connected with the circuit breaker remotely, and the aim of the invention is achieved.
Therefore, the user can immediately cut off the loop to generate the electricity safety protection function when the current reaches the rated electric quantity through the remotely controllable breaker (10) of the invention, and can also remotely detect and immediately know the real-time electricity consumption of the electrical equipment connected with the breaker (10). Because the electricity consumption is known in real time, the user can be based on reducing the electricity consumption, so that the electricity consumption can be concerned when using the electric appliance product, and the purpose of saving energy and using electricity can be realized invisibly. For example, when a user wants to select one of the first and second electrical products in the living room, if the user finds that the electricity consumption displayed in the living room circuit is less than that of the second electrical product when the first electrical product is used, the user can select the first electrical product in order to reduce the electricity consumption, and the effect of saving energy and using electricity is generated virtually. In addition, because the real-time electricity consumption is known, the user can estimate and predict the electricity consumption cost of the whole month by himself, if the user wants to reduce the electricity consumption, various electricity saving behaviors can be performed immediately, compared with the traditional method that the user needs to take the electricity bill after two months to know how much electricity is consumed, the user finds that electricity is saved and is not good for the change of the existing bill, and abandons any further behaviors, and obviously, the invention can achieve the function of saving energy and using electricity. In addition, for the conditions of sharing one electric meter by a plurality of units, such as collective housing, elegant room renting, office buildings, hotel guest room management systems, power system area management thereof and the like, a user cannot easily clearly calculate the electric quantity used by each unit and the electric charge must be distributed.
Another embodiment of the present invention is shown in fig. 4, 5 and 6; fig. 4 is a schematic block diagram of a remotely controllable circuit breaker according to a second embodiment of the present invention; fig. 5 is a schematic perspective view of a remotely controllable circuit breaker according to a second embodiment of the present invention, shown separated; fig. 6 is a perspective view illustrating a remotely controllable circuit breaker assembly according to a second embodiment of the present invention. The remotely controllable circuit breaker (10) comprises: a fuse-less switch (20), a magnetic latching relay (30), a current detection module (40), and a second microswitch (54). Similar to the previous embodiment, the fuseless switch (20) is opened up as a safety control loop, usually by integrating circuits in the same space in the same loop. One end of the fuse-less switch (20) is a power supply terminal (22), and the other end is a load terminal (24). The power terminal (22) of the fuseless switch (20) is electrically connected to an external power supply source (e.g., a power utility company), and the load terminal (24) is selectively electrically connected to one terminal of a magnetic latching relay (30) to assist the fuseless switch (20). The other end of the magnetic latching relay (30) passes through the current detection module (40) through the electric connection wire (32) and penetrates out of the other end of the current detection module (40) to form a power supply end (34), and the power supply end (34) is connected to energy-consuming electrical equipment in a building to provide power. When the electrical connection wire (32) passes through the current detection module (40), the current detection module (40) can detect the magnitude of the current flowing through the magnetic latching relay (30). A second microswitch (54) is provided on one side of the magnetic latching relay (30) for sensing the state of the magnetic latching relay (30). The second microswitch (54) is provided with a first signal wire (61) and a sixth signal wire (66), and the first signal wire (61) and the sixth signal wire (66) extend to the outside of the breaker (10) which can be remotely controlled and are connected to a signal output part (70). In addition, the current detection module (40) is provided with a second signal line (62) and a third signal line (63), is connected to the signal output part (70), and transmits the detected current amount to the signal output part (70) through the second signal line (62) and the third signal line (63). The magnetic latching relay (30) is provided with a fourth and a fifth signal lines (64) (65) connected to the signal output part (70), and the detected current amount is transmitted to the signal output part (70) through the fourth and the fifth signal lines (64) (65). The greatest difference from the previous embodiment is that the remotely controllable circuit breaker (10) is made up of two main parts, a receiving part (12) and a plug-in part (14). The receiving portion (12) accommodates the fuseless switch (20), and an operating handle (80) is provided on the front surface of the receiving portion, and the operating handle (80) is used for switching on or off a circuit controlled by the fuseless switch (20). A first combining hole (13) is provided at a proper position below the operating handle (80), and a jack (not shown) is provided at a bottom surface perpendicular to the front surface of the operating handle (80). The plug-in part (14) houses a magnetic latching relay (30), a current detection module (40), a second microswitch (54) and the like, and is designed in the form of a plug-in that can be used on a circuit breaker using a branch circuit in an electrical panel without changing existing equipment. The front surface of the plug-in part (14) is provided with a manual operating rod (90), the manual operating rod (90) is provided with a state indicating cover, and when the internal warning light is changed from a green light to a red light, a user can manually operate the magnetic latching relay (30) through the manual operating rod (90). In the plug-in part (14), a connecting seat (15) is arranged on the top surface vertical to the front surface of the manual operating rod (90), and a second combining hole (16) is arranged on the front surface of the connecting seat (15). The connecting seat (15) of the plug-in part (14) can be just inserted into the jack of the receiving part (12), and then a connecting device (18) passes through the first combining hole (13) of the receiving part (12) and the second combining hole (16) of the plug-in part (14) to combine the two to form the breaker (10) capable of being remotely controlled. For example, the first and second coupling holes (13, 16) may be threaded holes, and the connecting means (18) may be bolts, by which the receiving portion (12) and the insertion portion (14) are coupled, although other coupling means are also possible. When the connecting device (18) passes through the first and second combining holes (13) (16) and is locked, the load terminal (24) of the magnetic latching relay (30) which is selectively and electrically connected with the fuse-free switch (20) is selectively conducted, namely, the receiving part (12) and the plug-in part (14) are both electrically conducted, namely, the broken line of fig. 4 is changed into a solid line, and the fuse-free switch (20) and the magnetic latching relay (30) are electrically connected. The first, second, third, fourth, fifth and sixth signal lines (61) (62) (63) (64) (65) (66) are extended out of the plug-in unit (14) and connected to a signal output unit (70). The user can remotely detect and predict the real-time power consumption of the loop, or manage and control the connected energy-consuming electrical equipment or service space by inserting another operation platform (not shown) into the signal output hole (72) of the signal output part (70). Therefore, the embodiment can upgrade the traditional fuse-free switch (20) equipment to have the function of remote monitoring only by inserting the plug-in part (14) into the traditional fuse-free switch (20) (namely the receiving part (12)) without changing the traditional fuse-free switch (20).
Referring to fig. 7, a third embodiment of the present invention is shown. Fig. 7 is a perspective view of a remotely controllable circuit breaker according to a third embodiment of the present invention. The single set of remotely controllable circuit breakers (10) of the first embodiment described above can only trip one conductor. In this embodiment, a plurality of sets of remotely controllable circuit breakers (10) are combined to form a plurality of remotely controllable circuit breakers (100), but only one operating handle (80) is provided to switch on or off the non-fuse switch (20), and a manual operating lever (90) is provided to operate the magnetic latching relay (30). Each set of circuit breaker (10) has an independent non-fuse switch (20), a magnetic latching relay (30), a current detection module (40), a first micro switch (52), a second micro switch (54), and first, second, third, fourth, fifth, and sixth signal lines (61) (62) (63) (64) (65) (66), wherein the plurality of sets of first, second, third, fourth, fifth, and sixth signal lines (61) (62) (63) (64) (65) (66) are connected to the same signal output part (70), and the operation principle is not repeated as described above. Therefore, the present embodiment combines a plurality of sets of remotely controllable circuit breakers (10), which can simultaneously open and break a plurality of wires, thereby improving the selectivity of users.
In summary, the circuit breaker capable of being remotely controlled according to the present invention, through the arrangement of the non-fuse switch, the magnetic latching relay, the current detection module, etc., not only can generate the protection function of electricity safety, but also can let the user clearly know the real-time electricity consumption, immediately perform the operation of saving electricity, reduce the waste of electric energy, and be suitable for industrial utilization. The traditional equipment can be upgraded to the function of remote monitoring without changing the traditional fuse-free switch equipment, and the method has more efficiency improvement and advancement compared with the prior art. The invention is not disclosed in the publication before the application, and its novelty is no doubt.
