[0021] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without making creative efforts should belong to the scope of protection of the present application.

[0022] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0023] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0024] In addition, in addition to being used to indicate the orientation or positional relationship, the above-mentioned part of the terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain attachment relationship or connection relationship in some cases. For the person skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific circumstances.

[0025] In addition, the terms "mount", "set", "provided with", "connected", "connected", "sleeved" should be broadly understood. For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two devices, elements or components. For the person skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0026] The inventor found that there are multiple methods for inputting the fixed value into the protection device, and the commonly used methods are the device panel button input method and the communication input method. The panel button input method is simple and intuitive, but the display window on the protection device is small, and the content that can be displayed on one screen is limited, the buttons are few and reused. The communication input method needs to be connected with a communication line, and a special software is used to realize the input and verification of the fixed value. The operation on the computer is simple and convenient, but when operating in the low-voltage switch room, the connection of the communication line needs to be changed constantly, which is troublesome and unsafe in the working environment. With the progress of electronic technology, the technology of designing a USB interface on the protection device is relatively mature, and the U disk has the characteristics of low price, easy procurement, large storage capacity, convenient carrying, and live plugging.

[0027] Using the USB interface and the U disk, the fixed value table of the protection device can be quickly generated according to the setting principle and the fixed value table provided by the protection device manufacturer. After adjustment and verification by the operation and maintenance personnel, the formal protection device fixed value is formed, and the quick input and automatic verification of the fixed value into the protection device become possible. In order to better enable users to master the basic data of the motor operation on site, the low-voltage protection device can realize 10 groups of recording waveforms by relying on powerful hardware resources and perfect software algorithms. The maximum recording time of each group can be set and the longest is 30 seconds, including 250 ms of recording wave signal before starting and 250 ms after returning, and the sampling rate is as high as 1200 Hz; the recording wave contains rich signal data (three-phase current, three-phase voltage, leakage current, opening-in variable position, opening-out variable position, etc.); through the USB interface, high-speed import and export of files is realized. At the same time, the event record in the protection device can be exported through the USB interface, and by comparing and analyzing the recording wave file and the event record, the problem can be located more accurately. This helps to greatly reduce the work burden of the operation and maintenance personnel. The product sequence number provided by the management standard protection device manufacturer is unique. The sequence number is mainly used to query the detailed information of the product, such as the model, configuration, and operation information of the protection device, which is convenient for the protection device manufacturer to provide after-sales service. Each protection device has a unique sequence number, which can be found on the cover or shell of the protection device. The protection device is installed on the low-voltage switch cabinet, which is associated with the specific electrical primary equipment. After the association, the running fixed value and working condition information of the electrical primary equipment can be obtained from the protection device. The product sequence number has no meaning for the operation and maintenance personnel and is not easy to remember. The operation and maintenance personnel are familiar with the primary equipment, and in order to facilitate management, the enterprise will number the electrical equipment according to the standard or rule, which is the equipment position number. The equipment position number has rules, and experienced operation and maintenance personnel can obtain a lot of useful information from the equipment position number and quickly remember the equipment position number. If the product sequence number and the equipment position number can be associated, and the fixed value file of the protection device is quickly located in the U disk through the equipment position number, the access to the fixed value of the protection device and the export of the recording wave file and the event record can be completed. Therefore, the low-voltage protection device with a USB interface is provided in the embodiments of the present application to improve the operation and maintenance efficiency.
