By clicking the same option in the test software and selecting the scan code connection button, you can realize the communication and interconnection between the test software and the host. The test software will record this information after the first connection. The next time you connect, you can select the automatic reconnection function in the Bluetooth connection option to quickly connect to the host.

[0015] Preferably, the data test includes a test parameter setting interface and a test process interface. Click to enter to enter the parameter setting interface.

The routine test function area includes low voltage test items such as intelligent sequence test, mechanical property test, contact resistance test and coil resistance test.

[0019] Preferably, click the historical data button on the display screen homepage. When the host has stored at least one set of test data, the system will sort the test data according to the storage time and display the most recently saved data by default. If the host has not stored any data, the page will not jump and an error warning sound will be issued.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0049] Function and operation instructions

[0050] The host of this machine uses a 7-inch resistive full-color touch screen, and the menu interface can be switched to full Chinese display, which is simple, fast, convenient and easy to understand. This machine is equipped with a customized Android APP (test software) application "Zongce 3", and its operation interface is proportionally modeled after the host LCD display interface design, achieving "zero" learning cost. The APP and the host are connected through the BLE4.0 Bluetooth module. After the connection, the operation is consistent with the LCD and the data transmission is stable. Therefore, the subsequent function introduction will focus on the host screen operation. Except for some special functions, the use of the APP will not be repeated.

[0051] Interface Introduction

[0052] The machine menu is designed in the style of a smartphone UI. The page is divided into three parts: the top status area, the middle content area, and the bottom button area (there is no such item on the homepage). The top status area mainly displays the date and time, smart voice volume, USB disk status, APP Bluetooth connection status, and some prompt text; the middle content area is the main display and operation area for the instrument menu content, which is also the part that is emphasized in the subsequent operating instructions; the bottom button area mainly displays icon buttons related to screen switching pages, data storage, printing, and testing. When the buttons in the interface are operated normally, the device will emit a pleasant dripping sound, and when an invalid operation is performed, the device will emit an error sound that is quite different from the dripping sound, so please pay attention to the distinction.

[0053] Home

[0054] The instrument main menu has four first-level menus: "Data Test", "Historical Data", "Clock Modification" and "System Settings".

[0055] The “data test” includes the circuit breaker mechanical characteristic test, contact resistance test, coil resistance test and energy storage motor energy storage and other functions, including the “intelligent sequence test” function that this machine strongly recommends.

[0056] In "Historical Data", you can view the test data saved when the instrument performed various types of tests before, and print, store, delete, etc. as needed.

[0057] "Clock Modification" is used to display and modify the system clock. When the device is connected to a smart device, click the "Clock Modification" button in the APP to quickly synchronize the date and time between the host and the smart device.

[0058] In "System Settings", you can set some states of the host, such as adjusting the LCD display brightness, switching the host display language (supported by some versions), setting the volume of the intelligent voice, etc. The "Bluetooth Connection" option is a QR code containing the hardware information of the instrument's built-in Bluetooth module. By clicking the same option in the APP and selecting the "Scan Code to Connect" button, the APP and the host can communicate and interconnect. The APP will record this information after the first connection. The next time you connect, you can select the "Auto Reconnect" function in the "Bluetooth Connection" option to quickly connect to the host (the host needs to remain powered on).

[0059] Data Testing

[0060] This is the core area for the instrument to complete the test, which includes the test parameter setting interface and the test process interface. Click to enter the parameter setting interface. The central content display area of ​​the interface is divided into three areas: test information setting area, circuit breaker break status display area and function parameter setting area.

[0061] The content of the test information setting area is general settings, in which, except for the test date which will be updated in real time with the system date and time (cannot be changed manually), the other three parameters will be updated and saved synchronously when changed in different test types and modes. The way to change it is to click the parameter display area to change it in the pop-up menu.

[0062] The circuit breaker status area displays the closing and opening status of the circuit breaker detected by the current device. The judgment channel will be determined by the "test type" and "sequential control test port" mentioned in the subsequent introduction.

[0063] The function parameter setting area is divided into three function areas: "General Test", "Low Voltage Action" and "Motor Energy Storage". When entering the "Low Voltage Test" menu, the default entry is the "General Test" function area. Click the corresponding function area text to switch. The "General Test" function area includes the main low-voltage test items such as intelligent sequence test, mechanical property test, contact resistance test, coil resistance test, etc. "Low Voltage Action" and "Motor Energy Storage" provide the functional operations in their literal meanings. When all parameter settings are completed and the test lines are connected, click the button to perform the test items selected in the "Test Type", and the latter two have start buttons set in the function parameter setting area.

[0064] The following is a description of the parameters in the "General Test" function area:

[0065] Test Type

[0066] Click this display button, and the menu will jump to the test type setting interface. There are four radio options for the test type: "Intelligent Sequential Test", "Mechanical Characteristics", "Contact Resistance", and "Coil Resistance". The latter three items represent the three low-voltage test items that the device can achieve, and "Intelligent Sequential Test" combines the above three basic functions with "Manual Opening and Closing" and "Motor Energy Storage" in "Low Voltage Action" to automatically generate a set of reasonable action sequences to achieve the purpose of completing all the test items selected in "Intelligent Sequential Test Item Setting" in one wiring. The content displayed in the black background area above the circuit breaker break status display area is the order of the test items in the "Intelligent Sequential Test" to be carried out. The red horizontal line indicates that this item is included, and the white horizontal line indicates that this item is not included. The content of the "Number of Low Voltage Cycles" parameter setting is the number of cycles of the closing low voltage test and the opening low voltage test in the "Intelligent Sequential Test", and the setting range is 1-5. When this parameter value is greater than 1, except for the first initial voltage being the "initial voltage" in the "low voltage action", the initial voltage thereafter will default to the last action voltage.

[0067] The parameter setting of "Sequential Control Interval Waiting Time" is the waiting time between two test items in "Intelligent Sequential Test".

[0068] Sequential control test port

[0069] This parameter provides two options, "A1B1C1" and "A2B2C2". Clicking the button will display them in a loop. When introducing the circuit breaker break status area, it was mentioned that the break detection channel of the device is determined by the two parameters "test type" and "sequential control test port". When the "test type" is set to "intelligent sequential test", the break detection channel is set to (5), (6), (7), and (8) on the panel as the input terminal. The content displayed by the "sequential control test port" button is the break status channel. Switching the button option will change the channel. When the "test type" is set to other options, the break detection channel is the four data channels (16), (17), (18), and (19) on the panel (i.e. "A2B2C2", "A1B1C1", "A3B3C3", and "A4B4C4"). At this time, clicking the "sequential control test port" is an invalid action.

[0070] Contact resistance test duration

[0071] This parameter provides 4 gears: "15s", "30s", "45s" and "60s". Click the button to display them in sequence.

[0072] Contact resistance test current

[0073] This parameter only provides the "100A" gear.

[0074] Coil resistance test current

[0075] This parameter only provides the "Auto" gear and the maximum output current is ≤3A.

[0076] Mechanical characteristics trigger mode

[0077] This parameter provides two options, "Internal Trigger" and "External Trigger". Click the button to display them in a loop. "Internal Trigger" mode means that the internal DC power output of the instrument is used during the test to drive the opening / closing coil of the device under test to achieve the opening and closing action of the device under test; "External Trigger" mode means that the internal DC source of the instrument does not work, but drives the opening / closing coil of the device under test through other power sources, and the instrument only collects the external voltage action signal as the timing starting point. This parameter can only be selected in the "Automatic Test", "Opening Test" and "Closing Test" modes, and the default setting is "Internal Trigger" in other modes.

[0078] Mechanical properties test mode

[0079] This parameter provides 5 options: "Automatic test", "Opening test", "Closing test", "Opening and closing test", "Closing and opening test" and "Opening and closing and opening". Clicking the button will display them in a loop. Among them, the "Automatic test" mode is that the instrument independently determines to perform opening or closing test according to the current port status (opening test is performed when one of the 12 breakers is in the closed state). Users can select the corresponding test mode according to the test requirements and the current break status.

[0080] Mechanical characteristics Output voltage

[0081] The setting range of this parameter is 5-270. Click the parameter display button to pop up the input interface.

[0082] Speed ​​Definition

[0083] Click this display button to enter the speed definition menu. This parameter provides 10 common calculation rules for opening / closing speeds and a custom rule to meet the factory opening / closing speed requirements of high-voltage switches of different manufacturers and models. If the above rules cannot meet the definition requirements, you can first select any speed definition for testing. After the test is completed, manually select a specific time or displacement interval on the "Time-Stroke Characteristic Curve" in the "Curve Graph" for analysis to obtain the corresponding average speed. This method is also applicable to situations where the definition selection before the test is incorrect.

[0084] Mechanical characteristics switch displacement

[0085] The setting range of this parameter is 0.1-999.9. Click the parameter display button to pop up the input interface. It should be noted that the input value of this parameter is related to the type of sensor selected. When an angle sensor is selected, the input value should be the total stroke (open distance + overtravel) of the moving contact of the device under test; when a linear sensor is selected, the input value should be the total range marked on the linear sensor (the total range of the standard sensor is 50.0mm).

[0086] Sensor location

[0087] This parameter provides 3 options: "Phase A", "Phase B" and "Phase C". Click the button to display them in sequence. It indicates the installation position of the sensor. The parameter setting content should be consistent with the installation position of the sensor; if an angle sensor is selected and the three phases ABC are the same rotation axis, it can be set arbitrarily.

[0088] Sensor Type

[0089] This parameter provides two options: "Displacement Sensor" and "Angle Sensor". Click the button to display them in sequence.

[0090] Reclosing opening time, reclosing closing time

[0091] Both parameters are digitally adjustable from "5ms" to "1000ms". Clicking the button will display them in a loop. The two settings are only valid when the mechanical characteristic test mode is "open and close", "close and open" and "open and close and open". They mean the test duration of the opening test action and the closing test action in the reclosing test. Therefore, when setting the two, the value of "mechanical characteristic test duration" should satisfy the following formula:

[0092] When the test mode is "open and close" and "close and open": T (test duration) ≥ T (opening time) + T (closing time)

[0093] When the test mode is "open / close": T (test duration) ≥ 2*T (opening time) + T (closing time)

[0094] When the two parameters do not meet the above requirements when they are set, the instrument will automatically change the value of "Mechanical Properties Test Duration" to meet the requirements.

[0095] Mechanical properties test duration

[0096] This parameter provides 5 gears: "250ms", "500ms", "1000ms", "2000ms", and "4000ms". Click the button to display them in sequence. When the mechanical characteristic test mode is "open and close", "close and open" and "open and close and open", when changing the parameter value, the instrument will automatically skip the time gear that does not meet the requirements of the above reclosing time setting.

[0097] The following is the parameter description of the "Low Voltage Action" function area:

[0098] Initial voltage

[0099] The setting range of this parameter is 5-270. Click the parameter display button to pop up the input interface. It is the starting voltage of low voltage closing / opening action.

[0100] Step voltage

[0101] The setting range of this parameter is 1-10. Click the parameter display button to pop up the input interface.

[0102] Action Mode

[0103] This parameter shows the upcoming action mode, which is automatically determined and set by the instrument based on the current collected break state and cannot be changed. The judgment basis is the same as the "mechanical characteristics test mode", that is, when one of the 12 breakers is in the closed state, the opening action is performed, otherwise the closing action is performed.

[0104] Pulse Width

[0105] The setting range of this parameter is 1-2000. Click the parameter display button to pop up the input interface. The parameter represents the duration of a low voltage action.

[0106] Continuous boost (stop boost), single boost, manual opening and closing

[0107] The three are the start buttons for the low voltage action test, representing three working modes respectively.

[0108] "Continuous boost" means that the output voltage is output multiple times continuously, and the output voltage value starts from the "initial voltage" value, and then accumulates a "step voltage" value each time until the instrument detects that the break state has changed or the "stop boost" button is pressed to stop the output. When the output voltage value exceeds the maximum output voltage value (270V), the output will also stop and a voice warning will be issued.

[0109] "Single boost" means that the voltage is output only once, and the output voltage value is the last output voltage value plus a "step voltage" value. If it is the first action, the output voltage value is the "initial voltage" value; if the last output is "continuous boost" and it is stopped by pressing the "stop boost" button, the output voltage value will be the last "continuous boost" output value plus a "step voltage" value. The parameters are reset after re-entering this function area.

[0110] “Manual opening and closing” means to output voltage once according to the “initial voltage” value.

[0111] The following is a description of the parameters in the "Motor Energy Storage" function area:

[0112] Voltage

[0113] The setting range of this parameter is 5-270. Click the parameter display button to pop up the input interface.

[0114] Time, current

[0115] These two parameters are the duration of energy storage output and the instantaneous current of energy storage output, which are non-configurable parameters.

[0116] Start energy storage (stop energy storage)

[0117] This button is the start button for the energy storage action. After clicking "Start Energy Storage", the button displays "Stop Energy Storage", and the instrument starts to output constant voltage according to the set "voltage" value. At the same time, "time" and "current" begin to update in real time. At this time, clicking the button again will stop the output and display "Start Energy Storage". When the output time exceeds 10s and the output current is less than the preset current threshold for a certain period of time, it is determined that the energy storage action is completed or the energy storage circuit is open, and the instrument will also stop output and reset the display.

[0118] Historical data

[0119] Click the "Historical Data" button on the home page. When the instrument has stored at least one set of test data, the system will sort the test data according to the storage time and display the most recently saved data by default. If the instrument does not store any data, the page will not jump and an error warning sound will be issued. The data stored in this machine can be divided into intelligent sequential test data, mechanical property data, and low-voltage resistance test data (including contact resistance and coil resistance). The first two data types are automatically saved by the system after the test is completed, and the data display interface of the two is basically the same.

[0120] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
