Description

Technical Field

[0001] This invention relates to the field of electrical switch technology, and in particular to a programmable power distribution device that combines a circuit breaker and a contactless switch. Background Technology

[0002] Traditional distribution boxes use contact-type circuit breakers assembled together to protect the corresponding electrical circuits from overload, leakage, and short circuits. Switches need to be installed between the distribution box and the electrical appliances, and these switches must be close to people's activity range, while the corresponding appliances are placed where they should be. This results in excessively long and messy wiring, and a high risk of electric shock and fire.

[0003] With the continuous development of society, people are using more and more electrical appliances in their work and home environments. If all of them are protected by traditional circuit breakers, the entire power distribution system will be enormous. If, in order to reduce size, many appliances are connected to a single circuit breaker, then the capacity of that circuit breaker must be very large. If one appliance malfunctions, the circuit breaker becomes ineffective, easily leading to a fire. Introducing modern intelligent IoT technology into traditional distribution boxes would further increase their size. With the increasing number and complexity of electrical applications, how can we make our work or home distribution boxes not only function as main power distribution protection but also as intelligent central control boxes, directly controlling the on / off state of electrical appliances, completely changing the traditional messy switch wiring, improving electrical safety, and ideally keeping the size of the distribution box unchanged? This is a problem that must be considered for the future. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

By combining a circuit breaker with a contactless switch, it can realize contactless switch control of low-power electrical equipment and improve the level of intelligent power distribution.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3 As shown, the circuit breaker and contactless switch combined programmable power distribution device provided by the present invention includes a main power distribution circuit breaker 8 and several branch circuit breakers 9 connected thereto, a main power distribution controller 1, and several contactless switch modules 2 electrically connected to the main power distribution controller 1. The branch circuit breakers 9 are located on one side of the main power distribution circuit breaker 8, and the main power distribution controller 1 is located on the other side. The main power distribution controller 1 is electrically connected to the main power distribution circuit breaker 8, and the contactless switch modules 2 are electrically connected to low-power electrical equipment. The contactless switch modules 2 are assembled from several modular individual contactless switches according to the number of power circuits. The contactless switch modules 2 are arranged side-by-side on the main power distribution controller.

[0025] The high-voltage power input to the main power distribution controller 1 comes from the main inlet power distribution circuit breaker 8 and is protected by the main inlet power distribution circuit breaker 8.

[0026] The device also includes a digital signal transmission line busbar 3 and a high-voltage busbar 4. The contactless switch module 2 is communicatively connected to the power distribution controller 1 via the digital signal transmission line busbar 3. The high-voltage power output by the power distribution controller 1 is transmitted to the contactless switch module 2 via the high-voltage busbar 4. The digital signal transmission line busbar 3 is equipped with four digital signal transmission lines.

[0027] The power output terminal of the contactless switch module 2 is provided with a high-voltage output terminal 5, and the high-voltage output terminal 5 is connected to a high-voltage output terminal block 6.

[0028] The contactless switch module 2 is connected to a USB remote control port 7, which is electrically connected to a remote low-voltage manual control switch 10 via a USB data cable.

[0029] like Figure 3 As shown, the contactless switch module 2 includes a housing and a microprocessor 12, a high-voltage input terminal block 15, a digital signal connector 16, and several thyristors 11 disposed on the housing. The high-voltage input terminal block 15 is connected to the high-voltage busbar 4, the digital signal connector 16 is connected to the digital signal transmission line 3, the thyristors 11 are connected to the high-voltage input terminal block 15, and the microprocessor 12 is electrically connected to the thyristors 11 and the digital signal connector 16 respectively.

[0030] The contactless switch module 2 also includes a flip cover 13 and an LED indicator 14. The flip cover 13 is hinged to the housing and is used to cover the high-voltage input terminal 15 and the digital signal connection port 16. The LED indicator 14 is used to reflect the on / off state of the thyristor 11.

[0031] The main power distribution controller 1 includes a CPU and a wireless network module. The CPU communicates with a remote control terminal through the wireless network module.

[0032] The high-voltage input terminal 15 and the high-voltage busbar 4 are threadedly fastened together. Here, the contactless switch module 2 receives high-voltage power from the power distribution controller 1. The four digital signal connectors 16 and four digital signal transmission lines are connected here to realize data communication between the CPU and microprocessor 12 of the power distribution controller 1. The microprocessor 12 is located inside the contactless switch module 2. In this embodiment, three silicon controlled rectifiers (SCRs) 11 are also provided. High-voltage power is transmitted through the SCRs 11 to the corresponding three high-voltage output terminals 5, and then directly supplied to the electrical equipment through the high-voltage output terminal block 6, without the need for a series switch.

[0033] The microprocessor 12 controls the opening and closing of the three thyristors 11, simultaneously monitors the power output metering of each output port, and provides current limiting functionality for safety protection. All the aforementioned intelligent circuit breakers and contactless switches are controlled by the main power distribution controller 1, and are connected to the internet via the internal wireless network module of the main power distribution controller 1, thereby connecting to a remote control terminal for convenient intelligent network control. To respect traditional practices, each contactless switch module 2 is equipped with a USB remote control port 7, which connects to switches installed in conventional locations via low-voltage communication cables. These switches control circuits with a safe voltage of less than 30 volts, changing the traditional direct series high-voltage live wire control to indirect low-voltage control.

[0034] The main power distribution circuit breaker 8 and several branch circuit breakers 9 are leakage current, current limiting, short circuit protection circuit breakers or intelligent circuit breakers. The purpose of this type of contact circuit breaker is to meet the needs of traditional high-power circuits. This embodiment uses an intelligent circuit breaker that automatically trips when power is lost and automatically recloses when power is restored.

[0035] The conduction of the thyristor 11 is controlled not only by the CPU inside the power distribution controller 1 through the digital signal transmission line 3, but also by the microprocessor 12 inside the contactless switch module 2, and by the remote low-voltage manual control switch 10 through the USB remote control port 7; the microprocessor 12 provides current limiting protection for each output port, as well as power metering management.

[0036] This invention changes the layout of traditional power distribution and consumption systems. Instead of laying high-voltage wires between the distribution box and the electrical appliances, the electrical appliances are directly connected to the distribution box, eliminating messy wiring in our surroundings and greatly reducing the risk of fire and electric shock. Furthermore, it enables our home and work power distribution systems to achieve intelligent and Internet of Things (IoT) integration.

[0037] The circuit breaker and contactless switch combined programmable power distribution device provided by this invention combines a contact circuit breaker and a contactless switch, enabling contactless switch control of low-power electrical equipment while ensuring that traditional circuit breakers can control the switching of high-power electrical equipment. The contactless switch module adopts a modular standardized design, which can be arbitrarily assembled according to the number of electrical circuits required, transforming the traditional distribution box into a main power distribution and control box, directly outputting high-voltage power to the electrical equipment. Through the connection of the main power distribution controller and a remote control terminal, users can conveniently control electrical appliances using intelligent network methods. Users no longer need to directly touch the high-voltage switches, greatly shortening the high-voltage wiring and significantly improving safety performance. At the same time, it also facilitates the intelligentization and Internet of Things interconnection of the distribution box. In addition, in order to retain traditional power usage habits, wireless switches or USB low-voltage connection switches can be installed in the traditional switch locations to realize multiple modes of switch control.
