Description

Technical Field

[0001] This invention relates to the field of circuit testing technology, and in particular to an emergency AC power station control panel testing bench and testing method. Background Technology

[0002] Currently, the electrical installation inspection of emergency AC substation control panels requires checking the control aviation socket section. Inspecting this section typically requires multiple people and only allows for measuring the correctness of the wiring soldering. It's difficult to check the outer edge of the control aviation socket and whether the contacts are misaligned. The control aviation socket contains multiple contacts with very limited space between adjacent contacts. Due to space constraints, external testing tools can only test individual connection points when inspecting the internal wiring of the emergency AC substation control panel. After testing, the external testing tools must be removed and reconnected to another connection point for testing. This results in low inspection efficiency for emergency AC substation control panels. Summary of the Invention

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] It should be noted that the emergency AC power station control panel test bench in this application is used to test the emergency AC power station control panel. The first external plug 120 in this application is a multi-pin aviation plug. The emergency AC power station control panel (hereinafter referred to as the product control panel) is provided with a control aviation socket, and the aviation plug is correspondingly plugged into the control aviation socket. The multiple pins of the aviation plug are inserted one-to-one into the multiple sockets of the control aviation socket.

[0020] It should be noted that the first AC power connector 10 in this application is an AC power three-pin plug and wire harness, and the second AC power connector 50 is an AC power four-pin plug and wire harness.

[0021] Example 1 like Figure 1As shown, the present invention provides an emergency AC power station control panel test bench, which includes a first AC power connector 10, an AC to DC converter 20, a DC test circuit assembly 30, a first set of terminal block assemblies 40, and a first external plug 120. The system includes a first AC power connector 10 electrically connected to an external AC power source, an AC-to-DC module 20 electrically connected to the first AC power connector 10, a DC test circuit assembly 30 electrically connected to the AC-to-DC module 20, a first set of terminal blocks 40 electrically connected to the DC test circuit assembly 30, and a first external plug 120, one end of which is electrically connected to the first set of terminal blocks 40, and the other end of which is plugged into the socket of the emergency AC power station control panel to be tested. The DC test circuit assembly 30 includes multiple function detection circuits 35, each function detection circuit 35 having a DC indicator light 351, which is electrically connected to the corresponding port in the first set of terminal blocks 40. When a function detection circuit 35 is turned on, the corresponding DC indicator light 351 is lit; when a function detection circuit 35 is turned off, the corresponding DC indicator light 351 is turned off, indicating that the wiring of the corresponding line in the emergency AC power station control panel is correct and the components on the line are working normally.

[0022] In the above setup, the first external plug 120 (the aforementioned aviation plug) is connected to the control aviation socket of the product control panel (emergency AC power station control panel). If it cannot be plugged in or is not firmly plugged in, it indicates that the outer edge of the control aviation socket is deformed or the aviation pin contacts are misaligned. That is, the first external plug 120 can detect the misalignment of the outer edge and contacts of the aviation socket. This avoids the problem in existing technologies where the misalignment of the outer edge and contacts of the control aviation socket cannot be checked, thereby improving the installation accuracy of the control aviation socket.

[0023] Furthermore, a first external plug 120 is provided, which is connected to the control aviation socket on the back of the product control panel. This allows multiple functional testing circuits 35 of the emergency AC power station control panel test bench to be electrically connected to the control aviation socket. Thus, the corresponding functional lines within the product control panel can be quickly tested through each functional testing circuit 35. In other words, the emergency AC power station control panel test bench can achieve rapid testing of multiple functional lines within the product control panel, thereby improving the testing efficiency of the product control panel.

[0050] Example 2 like Figure 10 As shown, the present invention provides a method for inspecting an emergency AC substation control panel. The inspection method uses the aforementioned emergency AC substation control panel inspection test bench and includes the following steps: The first external plug is connected to the socket on the emergency AC power station control panel; The functional testing circuit tests the corresponding lines within the control panel of the emergency AC power station; Based on the display status of the DC indicator light on the function detection circuit, it is determined whether the corresponding wiring in the emergency AC power station control panel is correct and whether the components on the wiring are working properly.

[0051] The second external plug connects to the socket on the emergency AC power station control panel; The AC test circuit tests the corresponding lines within the control panel of the emergency AC power station; Based on the display status of the AC indicator light on the AC test circuit, determine whether the corresponding wiring in the control panel of the emergency AC power station is correct and whether the components on the wiring are working properly.

[0052] The testing method in this embodiment will be explained in detail below: Step 1: Place the emergency AC power station control panel test bench carrying case (case size 80) on one side of the control panel, lock the four casters at the bottom of the carrying case, and securely insert the aviation connector on the control panel test bench into the aviation socket on the back of the product control panel. If it cannot be inserted or is not securely inserted, it indicates that the outer edge of the aviation socket is deformed or the aviation connector pin is misaligned. Securely insert the four alligator clip connectors of the four locking alligator clip wire harnesses (U, V, W, N lines) into the corresponding U, V, W, and N wire terminals inside the product control panel.

[0053] Step 2: Using a multimeter, measure the corresponding wires (B+, 811, 812, 813, 814, 700, 701, 800, D+, 611, 612, 613, 614, U, V, W, and N) on the test bench according to the wiring diagram. If the corresponding points are connected, the wiring is correct; otherwise, the wiring in the product control panel is incorrect and the product needs to be reworked.

[0054] Step 3: On the emergency AC power station control panel test bench, connect the positive wire of the AC-to-DC 24V power supply module above the 1QF miniature circuit breaker (first miniature circuit breaker) and the B+ wire below it. On the test bench, connect the negative wire of the AC-to-DC 24V power supply module above the 2QF miniature circuit breaker and the 800 wire below it. This simulates the inspection and operation of the product control panel wiring and components when the power station is not supplied with DC control power.

[0055] Step four: With the electric lock switch key on the product control panel in the "stop" position and the miniature circuit breaker in the "on" position, manually close the 1QF and 2QF miniature circuit breakers (the first and second miniature circuit breakers) on the emergency AC power station control panel test bench. Ensure the B+ and 800 lines are connected to DC 24V. Supply DC 24V to the product control panel. At this time, the DC power supply indicator light on the product control panel will illuminate, and the indicator lights for the B+ and 800 lines on the test bench will also illuminate. This indicates that the B+ line, 800 line, DC control miniature circuit breaker, and wiring within the product control panel are correct.
