Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliance testing devices, and in particular to a controller area interlocking auxiliary testing fixture. Background Technology

[0002] Controller area interlocking refers to the interlocking control of multiple devices or systems within a specific area through a controller. When a device or system fails, the area interlocking function can quickly disconnect the device from other devices to prevent the fault from spreading and protect other devices from damage. Alternatively, in a power system, the circuit breaker area interlocking function can quickly locate the fault point and isolate the fault area from other areas to ensure the stable operation of the power system.

[0003] However, the actual utilization rate of controllers with regional interlocking functions is currently low because the interlocking function is relatively difficult to verify, resulting in the regional interlocking function of the controllers rarely being applied in formal working environments. Furthermore, the testing and verification of regional selective interlocking functions are often neglected or omitted during product development, significantly reducing the practicality of this function.

[0004] In summary, existing controller area interlock function testing is cumbersome and inefficient, resulting in limited practical applications. Furthermore, testing and verification during the R&D phase are often neglected, leading to lower product safety and reliability. Therefore, there is a need for a controller area interlock auxiliary testing fixture that offers high testing efficiency and ease of use. Utility Model Content

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] Example 1

[0033] like Figure 1 and Figure 3 As shown, this embodiment provides a controller area interlocking auxiliary test fixture, including a mounting bracket 1, a fixing baffle 2, a line adapter assembly 3, and a transformer power supply module 4;

[0034] The mounting bracket 1 is provided with a mounting slot. The fixed baffle 2 is movable and mounted on the mounting bracket 1 to adjust the width of the mounting slot. The line adapter assembly 3 and the transformer power supply module 4 are both fixed on the mounting bracket 1. The transformer power supply module 4 is connected to the line adapter assembly 3.

[0035] Working principle: Place the controller to be tested into the mounting slot of the mounting bracket 1, move the fixed baffle 2, adjust the width of the mounting slot so that the mounting slot matches the controller and fixes the controller. Then connect the controller to the corresponding line adapter component 3. After that, the controller area interlock test can be completed by operating the controller.

[0036] By setting an adjustable mounting slot on the mounting bracket 1, various types of controllers can be fixed, expanding the applicability of the tooling, and the structure is simple and easy to adjust; and a line adapter component 3 is set on the mounting bracket 1, which integrates a test circuit. The controller's connection terminal can be directly connected to the line adapter component 3, simplifying the steps of controller area interlocking test and improving the efficiency of area interlocking test.

[0037] Specifically, the mounting bracket 1 has a guide hole on one side of the mounting groove, the fixed baffle 2 is located in the guide hole, and the lower end of the guide hole has a baffle positioning groove 5 that cooperates with the fixed baffle 2.

[0038] The number of baffle positioning slots 5 is multiple, and each baffle positioning slot 5 is evenly distributed along the guide hole. The height of the fixed baffle 2 is greater than the depth of the baffle positioning slot 5.

[0039] Based on the size of the controller to be tested, the fixing baffle 4 is moved along the guide hole and placed into the corresponding baffle slot 5 near the controller, thereby adjusting the width of the mounting slot to fit the controller and making adjustment convenient.

[0040] In a preferred embodiment, a fixing knob 6 is provided on the fixing baffle 2, and the fixing knob 6 is rotatably fixed on the fixing baffle 2. There are multiple fixing knobs 6, and each fixing knob 6 is evenly distributed on the fixing baffle 2.

[0041] Furthermore, the end of the fixed knob 6 near the mounting groove is provided with an elastic protective layer. The material of the elastic protective layer is preferably rubber.

[0042] A fixing knob is installed on the fixing baffle. The fixing knob can be rotatably installed on the fixing baffle. After the fixing baffle is brought close to the controller in the mounting slot, the fixing knob is rotated so that the end of the fixing knob with the elastic protective layer contacts the controller, thereby improving the installation stability and reliability of the controller.

[0043] Specifically, the tooling also includes a flux converter 9, which is fixed on the mounting bracket 1.

[0044] The line adapter component 3 includes a first output terminal, a second output terminal, a first input terminal, a second input terminal, a first voltage terminal, and a second voltage terminal; the second output terminal is connected to the first input terminal, the first output terminal is connected to the first voltage terminal, and the second input terminal is connected to the second voltage terminal.

[0045] Specifically, the mounting slot includes a first mounting part 7 and a second mounting part 8, which are symmetrically distributed on both sides of the line adapter assembly 3. Multiple fixing baffles 2 are used. The controller in the first mounting part 7 and the second mounting part 8 can be fixed using two fixing baffles 2.

[0046] like Figure 3 As shown, the specific working principle of the controller area interlocking test using this auxiliary test fixture for testing two controllers is as follows:

[0047] Install controller 1 as the upper level in the first mounting part 7, then make a coarse adjustment of the width by moving the fixed baffle 2, place it in the corresponding baffle slot 5, and then rotate the fixing knob 6 for fine adjustment and fixation; install controller 3 as the lower level in the second mounting part 8 and fix it in the same way.

[0048] Then, the positive terminal of the digital signal contact input of controller 1 is connected to the first input terminal (DI+) of line adapter component 3, and the negative terminal of the digital signal contact input is connected to the second input terminal (DI-) of line adapter component 3. The negative terminal of the digital signal contact output of controller 3 is connected to the first output terminal (DO+) of line adapter component 3, and the positive terminal of the digital signal contact output is connected to the second output terminal (DO-) of line adapter component 3. Inside line adapter component 3, the second output terminal (DO-) is connected to the first input terminal (DI+), the first output terminal (DO+) is connected to the first voltage terminal (220V+), and the second input terminal (DI-) is connected to the second voltage terminal (220V-).

[0049] The controller is equipped with short-delay protection. Simultaneously, analog signals are input to both controller 1 and controller 3, causing a fault in the lower-level controller 3. This causes the digital signal contact output of controller 3 to close, and the signal is transmitted from controller 3 through line adapter component 3 to the digital signal contact input of the upper-level controller 1, causing controller 1 to trip. This completes the test. It should be understood that this is an example for a level 2 controller; the same principle applies to level 3 and above.

[0050] By utilizing auxiliary testing fixtures, the regional interlocking function can be more conveniently and easily tested for completeness and feasibility during the R&D phase, reducing testing difficulty. This significantly reduces the difficulty of implementing regional interlocking tests during R&D, enhancing feasibility and practicality, and verifying the correctness and implementability of the controller's regional interlocking function.

[0051] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
