Description

Remotely controllable circuit breaker

The invention provides a remotely controllable circuit breaker, which is provided by the current detecting module and the signal output part, so that the user can remotely control the remotely controlled circuit breaker and the connected circuit The energy-consuming electrical equipment, or service space, for immediate management and control.

The traditional circuit breaker, commonly known as the no-fuse opening, usually integrates the circuits in the same space into the same circuit, and can form a short-circuit protection function when the power is overloaded. The principle of its operation is usually to use the physical thermal sensation to form a tripping circuit and to generate protection. However, it is usually classified by the rated current amount, and must flow more than the rated current, and the circuit breaker will operate. When the overload current is larger, the speed of the tripping is shorter, and the longer the tripping time is required. For example, if the rated current is 20 amps on the conventional circuit breaker, the current must flow more than 20 amps, the circuit breaker will act, and the automatic trip will form an open circuit. If all the plugs in a room are connected by the same shunt switch, if the shuntless switch of the shunt is rated at 20 amps and the total electrical power used by all plugs is 19 amps, then In theory, it is safe, and the fuseless switch does not trip. The term "trip" refers to the state in which the fuseless switch automatically "clicks" and jumps from ON to OFF. If the total power consumption is 21 amps, depending on the setting of the fuseless switch and the actual situation at the time, sometimes there will be some tolerance, of course, it will not trip, and the rated capacity is not much and time. It is very short. If it is only a few minutes, it may not be able to jump off. There is uncertainty in the link of safe use of electricity. However, if the load is 30 amps or higher, the normal fuseless switch will trip because it exceeds the load, but usually does not necessarily trip within a few seconds. Even without increasing the ampere rating to several times the rated 20 amp capacity, the fuseless switch will not trip immediately within a few seconds, and in the few seconds that have not yet tripped, because the current through it is very large, The circuit continues to be overloaded, and the temperature of electrical appliances and wires rises to a possible state of melting or even burning, resulting in a fire hazard. In addition, the traditional fuseless switch also has another function, which can immediately jump off and generate protection when the electrical fault or improper operation causes short circuit leakage. However, when the leakage current is small, the conventional fuseless switch does not trip. However, even if the leakage current is small, there is often a fatal danger. In the human body, the current through the heart may be fatal if it exceeds 100 milliamperes. If the current through the muscle exceeds 25 milliamperes, involuntary muscle contraction may occur, and the human body cannot be disconnected from the power source. In general, a fuseless switch below 30 mA should be tripped and the trip time is within 0.1 seconds. Of course, the smaller the trip current and the shorter the time, the safer it is. Obviously, the traditional no-fuse switch can not produce the function of protecting the human body, and it is impossible to perform remote monitoring to prevent the occurrence of electric shock accidents.

Therefore, it is concluded that the traditional circuit breakers usually have the following disadvantages: First, because the traditional circuit breakers are tripped and disconnected according to the way the metal physical thermal sensation rises, the current flowing through is equal to or slightly larger than the rated current. The traditional circuit breaker can not be tripped and disconnected immediately, and must wait for a period of time before it can be tripped and disconnected, resulting in delayed tripping and disconnection; while the tripping time is too long, the overload protection capability is insufficient, and the short circuit protection capability It is not satisfactory, because there is no self-function diagnosis ability, so it is impossible to distinguish between good and bad, and safety is really worrying. Second, it can only switch the line control of the same type of electrical appliances or energy-consuming facilities. There is no further extension of other technologies and functions other than power, and the overall function is weak. Third, the user can not immediately know the power consumption situation in the loop, can not immediately implement energy-saving measures, and does not have the function of energy saving. Fourth, the remote monitoring function is not available, and the user cannot manage and control at the remote end.

The present invention is mainly directed to the various shortcomings of the conventional circuit breaker described above, and is a completely new invention.

Usually, the circuits in the same space are integrated into the same circuit, for example, a general home, such as a master bedroom circuit, a living room circuit, a restaurant circuit, etc. The respective non-fuse switches (20) are respectively set to be controlled. When the current exceeds the rated current, the non-fuse switch (20) trips and cuts off the circuit to protect the safety of the circuit. One end of the no-fuse switch (20) is a power supply terminal (22), and the other end is a load terminal (24). The fuseless switch (20) should immediately generate an open circuit when the current exceeds the rated current. However, the fuseless switch (20) often cannot jump off immediately when the current exceeds the rated current, and must wait for the current to accumulate more than After a certain value of the rated current, the circuit breaker will trip and the tripping time is too long, and the overload protection capability is insufficient, so there is a risk of danger. Therefore, the load terminal (24) of the no-fuse switch (20) is electrically connected to one end of a magnetic holding relay (30) to assist the fuseless switch (20). When the current flowing through the magnetic holding relay (30) reaches the rated power, the fuseless switch (20) is started immediately, the circuit is cut off, and the circuit breaker is protected. The other end of the magnetic holding relay (30) passes through the current detecting module (40) through the electrical connecting line (32), and passes through the other end of the current detecting module (40) to form a power supply end.
