Description

Technical Field

[0001] The utility model relates to the technical field of intelligent circuit breakers, in particular to an intelligent circuit breaker housing and an intelligent circuit breaker. Background Art

[0002] As electricity usage scenarios in the market become more and more diverse, the requirements for electricity safety are also getting higher and higher. Traditional circuit breakers are difficult to meet such power distribution requirements. Therefore, smart circuit breakers with richer functions have become a new choice in the market. However, existing smart circuit breakers usually have the following problems: (1) The intelligent functions make smart circuit breakers larger than traditional circuit breakers, which cannot meet the needs of parallel replacement with traditional circuit breakers and are not suitable for installation and use in small distribution boxes; (2) The weak current that realizes the intelligent function and the strong current passing through the circuit breaker are in the same space, which is easily interfered by the strong point or the circuit breaker is disconnected. (1) The circuit breaker is damaged by the arc generated when the circuit breaker is opened and closed. When the circuit fails, the intelligent module may also fail, and the fault data cannot be transmitted. (2) There is a lack of monitoring of the most basic and core functions of the circuit breaker, such as monitoring the position of the circuit breaker contacts. (3) The intelligent circuit breaker uses a pin series connection method for data transmission. Once the middle circuit breaker fails, the circuit breakers at the back end cannot transmit data. In addition, the installation and maintenance of the circuit breaker are time-consuming and inconvenient. Therefore, how to design a small circuit breaker that can achieve isolation between strong and weak electricity has become a technical problem that technical personnel in this field need to solve urgently. Utility Model Content

[0003] One of the purposes of the utility model is to provide an intelligent circuit breaker housing, which realizes partial externalization of the intelligent unit module of the circuit breaker and externalization of the lines between the intelligent modules through the housing structure design, while maintaining the small size of the circuit breaker, realizes isolation between the strong current of the circuit breaker and the weak current of the intelligent module, and ensures the stability of the data transmission of the circuit breaker.

[0004] The second purpose of the utility model is to provide an intelligent circuit breaker, which detects the current data of the circuit breaker, the contact position of the circuit breaker, the temperature of the circuit breaker terminals and other parameters, and converts the circuit analog signal into a digital signal for parallel data output. Each intelligent module and the lines between them are installed on the intelligent circuit breaker housing provided by the utility model, thereby realizing a small intelligent circuit breaker with strong and weak electrical isolation.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions.

[0012] A second wire trough, the second wire trough connects the second mounting position and the third mounting position, and is used for laying out the lines of the components for connecting terminal temperature detection and the components for converting circuit analog signals into digital signals; and the second wire trough connects the second mounting position and the fourth mounting position, and is used for laying out the lines of the components for converting circuit analog signals into digital signals and the data transmission components.

[0013] Furthermore, the second installation position is also provided with a first cover plate for protecting the components at the second installation position and the lines of the second wire duct; the third installation position is also provided with a second cover plate for protecting the components at the third installation position.

[0014] An intelligent circuit breaker includes at least an incoming terminal bottom plate and uses the above-mentioned intelligent circuit breaker housing, including:

[0015] The current sensor is installed outside the circuit breaker inlet terminal plate to detect the circuit current data flowing into the circuit breaker;

[0016] A contact position detection module, installed at the first installation position, for detecting the position of the circuit breaker contact;

[0017] A digital-to-analog conversion module, installed at the second installation position, for converting the analog signals of the circuit breaker collected by each module into digital models and outputting them externally;

[0042] like Figure 3-4 shown.

[0043] An intelligent circuit breaker includes at least an incoming terminal bottom plate and uses the above-mentioned intelligent circuit breaker housing, including:

[0044] The current sensor 21 is installed outside the circuit breaker inlet terminal plate and is used to detect the circuit current data flowing into the circuit breaker;

[0045] A contact position detection module 22, installed at the first installation position 10, for detecting the position of the circuit breaker contact;

[0046] It should be noted that the contact position detection module 22 actually detects the position of the contact, which can directly reflect the opening and closing state of the circuit breaker. Compared with various indirect detections or digital signals, the detection of the contact position detection module 22 is not affected by various interference factors and can more directly and accurately reflect the opening and closing state of the circuit breaker.

[0047] A digital-to-analog conversion module 23, installed at the second installation position 11, is used to convert the circuit breaker analog signals collected by each module into digital models and output them externally;

[0048] A terminal temperature detection module 24, installed at the third installation position 12, for detecting the temperature of the circuit breaker terminal;

[0049] A data transmission module 25, installed at the fourth installation position 13, for outputting the data of the digital-to-analog conversion module 23 to the outside;

[0050] It should be noted that the data transmission module 25 is mounted on the end surface of the circuit breaker that matches the standard mounting rail, and can be connected to a circuit board disposed in the mounting rail to perform parallel data transmission.

[0051] A first wire (not shown) is installed in the first wire slot 14, connecting the contact position detection module 22 and the digital-to-analog conversion module 23, and is used for the contact position detection module 22 to transmit data to the digital-to-analog conversion module 23;

[0055] When working, the current sensor 21 transmits the current data, voltage data, etc. flowing through the circuit to the digital-to-analog conversion module 23 through the third wire, the contact position detection module 22 transmits the contact position signal to the digital-to-analog conversion module 23 through the first wire, and the terminal temperature detection module 24 transmits the real-time temperature signal of the terminal to the digital-to-analog conversion module 23 through the second wire. After that, the digital-to-analog conversion module 23 converts the analog signals transmitted by each module into digital signals, and outputs them to the outside through the fourth wire data and the transmission module 25.

[0056] It should be noted that during actual use, managers can accurately grasp circuit data and circuit opening and closing conditions through the signals output by the intelligent circuit breaker. In addition, if a circuit fails, managers can also determine the cause of the circuit failure and whether the circuit breaker has cut off the circuit through the signals output by the intelligent circuit breaker, so as to provide guidance for standardized operations before circuit maintenance and targeted maintenance operations.

[0057] It should be further explained that in actual application, the minimum width of the intelligent circuit breaker of this solution can reach 18 mm.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
