[0026] As mentioned above, there is a need for a dedicated testing apparatus for gas turbine control systems to verify their control functions and emergency shutdown reliability. However, no existing testing apparatus is available capable of testing gas turbine control systems.
[0027] To address at least the aforementioned problems, embodiments of this disclosure provide a test apparatus 1 for a gas turbine control system. Reference is made below. Figures 1 to 4 To describe the specific structure of the test apparatus according to this disclosure.
[0028] Figure 1 A front view of a test apparatus 1 according to an exemplary embodiment of the present disclosure is shown. Figure 2 It shows Figure 1 The rear view of the test apparatus 1 shown. Figure 3 It shows Figure 1 Side view of test device 1 in the image. Figure 4 It shows Figure 1 The bottom view of test device 1.
[0029] First, refer to Figure 1 From an overall structural perspective, the test device 1 for a gas turbine control system mainly consists of a base 20, a support 10, and an operating area 30. The base 20 serves as the fundamental support component of the entire test device 1, providing a stable mounting platform for other components. The support 10 is mounted on the base 20 and generally includes a first column 11, a second column 12, and a crossbeam 13, thus forming a frame structure to fix the operating area 30. The operating area 30 is configured to allow test personnel to generate various analog and digital signals for the gas turbine control system, thereby performing test operations on the gas turbine control system. The specific structure of each component will be described in detail below.
[0030] First, let's describe the base 20. For example... Figures 1 to 4As shown, the base 20 has multiple wheels 21 at its bottom, preferably brakeable wheels. When the test device 1 needs to be moved, the tester can push the test device 1 for easy movement. Especially in large factories or test sites, this setup allows for easy adjustment of the device's position to adapt to different test environment requirements. Once the test device 1 is moved to the designated test position, the wheels 21 can be locked by a braking mechanism to prevent the device from slipping during testing, ensuring stable and safe testing. Furthermore, to further enhance the stability of the device, the base 20 also includes feet 22 with threaded devices 221. By adjusting the height of the threaded devices 221, the contact state between the bottom surface 220 of the feet 22 and the ground can be changed. When the test site ground is uneven, the tester can rotate the threaded devices 221 to bring the bottom surface 220 of the feet 22 into contact with the ground, forming a stable support structure with the wheels 21, preventing the test device 1 from tilting due to uneven ground and ensuring the stability of the test device 1 during testing.
[0031] like Figure 3 As shown, from the surface structure of the base 20, the base 20 has multiple surfaces with different orientations. Specifically, the base 20 includes a first base surface 201, a second base surface 202, and a base top surface 203. Figure 3 In the illustrated embodiment, the first base surface 201 has the same orientation as the operating area 30, i.e., facing the side operated by the tester. The second base surface 202 faces the opposite direction to the first base surface 201, towards the back of the test device 1. The top surface 203 of the base is located at the top of the base 20 and abuts against the first column 11 and the second column 12 of the bracket 10, providing a flat and stable contact surface for the installation of the bracket 10.
[0032] The bracket 10 is described below with reference to the figures. The bracket 10 is mounted on the top surface 203 of the base 20 and includes a first side 101 and a second side 102 facing each other. The first side 101 faces the tester and provides an operating area 30, while the second side 102 faces the back of the device and is used to house the cable tray 40. Specifically, the bracket 10 consists of a first column 11, a second column 12, and a crossbeam 13, forming a frame structure. The first column 11 and the second column 12 are both fixedly mounted on the top surface 203 of the base 20 and are parallel to each other, forming a symmetrical support structure. The crossbeam 13 connects to the first column 11 and the second column 12, integrating them into a single unit, enhancing the overall rigidity of the bracket 10, and preventing the first column 11 and the second column 12 from tilting or deforming under load.
[0033] To accommodate the height requirements of the operating area 30 under different testing scenarios, the height of the first column 11 and / or the second column 12 is designed to be adjustable. Specifically, height adjustment can be achieved by incorporating a telescopic mechanism within the columns or by using a multi-segmented splicing structure secured with bolts. For example, when the test personnel are tall or the testing site has specific height requirements, the height of the first column 11 and the second column 12 can be adjusted to a suitable height, improving the test personnel's operational comfort while ensuring ease of observation and operation during testing.
[0034] like Figure 3 As shown, from the surface structure of the first column 11 and the second column 12, the first column 11 includes a first front surface 111 and a first rear surface 112. The first front surface 111 has the same orientation as the operating area 30, i.e., facing the tester's side, while the first rear surface 112 faces the opposite direction, towards the back of the device. Similarly, the second column 12 includes a second front surface 121 and a second rear surface 122. The second front surface 121 faces the same direction as the operating area 30, and the second rear surface 122 faces the back of the device. To facilitate the tester's movement of the testing device 1, the testing device 1 also includes a handle 15, which is disposed on the first front surface 111 and / or the second front surface 121, such as... Figure 1 As shown, the handles 15 are preferably symmetrically arranged on the front surfaces of the two columns. When the tester moves the device, he / she can hold the handles 15 with both hands to push the device, which not only saves effort but also allows for better control of the device's direction of movement, preventing the device from deviating or colliding during movement.
[0035] Furthermore, to ensure the stability of the connection between the first column 11 and the second column 12 and the base 20, and to avoid affecting the test accuracy due to column shaking during the test, the testing device 1 is also equipped with a first reinforcing plate 241 and a second reinforcing plate 242, such as... Figure 3 As shown. The first reinforcing plate 241 includes a first reinforcing edge 2411 and a second reinforcing edge 2412. The first reinforcing edge 2411 is connected to the top surface 203 of the base, and the second reinforcing edge 2412 is connected to the first front surface 111 of the first column 11 and / or the second front surface 121 of the second column 12. Figure 3 As shown, the first reinforcing plate 241 and the second reinforcing plate 242 are basically triangular. Through this triangular reinforcing structure, the first column 11 and / or the second column 12 are firmly connected to the base 20, thereby increasing the overall stability of the test device 1.
[0036] To ensure the reinforcement effect of the first reinforcing plate 241, its dimensional design must meet specific requirements. Specifically, the ratio of the length L1 of the first reinforcing edge 2411 and the height H1 of the second reinforcing edge 2412 of the first reinforcing plate 241 must be between 0.5 and 3. This ratio range was determined through extensive experimental verification. When the ratio is too small, the first reinforcing edge 2411 is too short, resulting in insufficient contact area with the top surface 203 of the base and inadequate reinforcement. When the ratio is too large, the second reinforcing edge 2412 is too low, failing to effectively improve the anti-tilting capacity of the column and easily causing the column to sway under load. Therefore, controlling this ratio between 0.5 and 3 ensures the reinforcement effect while avoiding excessive space occupation by the reinforcing plate, thus ensuring the compactness of the overall structure of the testing device 1.
[0037] Similarly, a second reinforcing plate 242 is disposed on the back of the column to further enhance the stability of the connection between the column and the base 20. The second reinforcing plate 242 includes a third reinforcing edge 2423 and a fourth reinforcing edge 2424. The third reinforcing edge 2423 is connected to the top surface 203 of the base, and the fourth reinforcing edge 2424 is connected to the first rear surface 112 of the first column 11 and / or the second rear surface 122 of the second column 12, as shown below. Figure 3 As shown. By symmetrically setting the first reinforcing plate 241 and the second reinforcing plate 242 on the front and rear sides of the column, a two-way reinforcing structure is formed, which can comprehensively resist external forces from different directions, further improve the structural stability of the bracket 10, and ensure that the connection between the column and the base 20 will not loosen during long-term use, providing a reliable guarantee for the stable operation of the operating area 30.
[0038] Similarly, the dimensions of the second reinforcing plate 242 must also meet specific proportional requirements. The ratio of the length L2 of its third reinforcing edge 2423 to the height H2 of its fourth reinforcing edge 2424 is between 0.5 and 3. This proportional setting is based on the same principle as the proportional requirement of the first reinforcing plate 241, both aiming to find the optimal balance between reinforcement effect and space occupation, ensuring that the second reinforcing plate 242 can effectively enhance the stability of the column without interfering with the installation of the cable tray 40 and the layout of other components on the back of the device.
[0039] From the perspective of the height relationship between the column and the base 20, as follows: Figure 3 As shown, the first front surface 111 and the second front surface 121 are a first distance D1 from the first base surface 201, and the first rear surface 112 and the second rear surface 122 are a second distance D2 from the second base surface 202, with the first distance D1 being smaller than the second distance D2. This dimensional design primarily considers the ease of operation of the testing device 1. Because the first distance D1 is smaller than the second distance D2, it facilitates the operation of the operating area 30 by the tester on the first side 101.
[0040] Furthermore, the height matching between the first reinforcing plate 241 and the second reinforcing plate 242 is also crucial. The ratio of the height H1 of the second reinforcing edge 2412 of the first reinforcing plate 241 to the height H2 of the fourth reinforcing edge 2424 of the second reinforcing plate 242 is between 1 and 10. This ratio design is mainly based on the force conditions on the front and rear sides of the column. Since the operating area 30 is located at the front of the column, the weight and external force borne at the front are relatively greater. Based on the lever principle, the height H1 of the first reinforcing plate 241 can be appropriately smaller than the height H2 of the second reinforcing plate 242, so that the second reinforcing plate 242 located at the rear is larger than the first reinforcing plate 241 located at the front, so as to better resist the external force on the front side, thereby realizing the coordinated work of the front and rear reinforcing plates and preventing the test device 1 from tipping over.
[0041] The operating area 30, as the core functional area of the testing device 1, is a key part for simulating and testing the signals of the gas turbine control system. For example... Figure 1 As shown, the operation area 30 is located on the first side 101 of the bracket 10, that is, the side facing the tester, to facilitate various operations by the tester. The operation area 30 includes a first panel 31 and a second panel 32, which are structurally independent but functionally complementary, respectively realizing the transmission and control of digital signals and analog signals.
[0042] Specifically, the first panel 31 is equipped with multiple digital switches 310 for transmitting various digital signals. These digital switches 310 are coupled to the gas turbine control system via multiple digital signal cables. The digital switches 310 are preferably high-reliability push-button switches or DIP switches. Each digital switch 310 corresponds to a specific digital signal channel and can independently control the signal on / off state or signal status of that channel, such as high or low level. During testing, the tester can operate the digital switches 310 to send various digital signals to the gas turbine control system, such as control command signals for starting, stopping, and speed adjustment.
[0043] The second panel 32 is equipped with multiple analog knobs 320 for transmitting multiple analog signals. These analog knobs 320 are coupled to the gas turbine control system via multiple analog signal cables. The analog knobs 320 are preferably high-precision rotary switches or slide switches. Each analog knob 320 corresponds to a specific analog signal channel, enabling continuous adjustment or level adjustment of the analog signal on that channel. The types of analog signals mainly include current signals and voltage signals.
[0044] like Figure 2As shown, the testing device 1 may also include cable trays 40. These cable trays 40 are located on the second side 102 of the support 10, i.e., on the back of the operating area 30. As shown, the cable trays 40 may be arranged in two rows, located on the back sides of the first column 11 and the second column 12, respectively. The cable trays 40 can form a receiving space capable of accommodating the plurality of digital signal cables extending from the first panel 31 and the plurality of analog signal cables extending from the second panel 32. Thus, numerous signal cables can be compactly housed and guided to the back of the testing device 1.
[0045] In addition, the top surface 203 of the base is also configured to support digital signal cables and analog signal cables. During signal transmission, various signal cables extending from the cable tray 40 can be coiled on the top surface 203 of the base to avoid confusion and damage caused by random placement of signal cables, while reducing interference during signal transmission and ensuring the stability of signal transmission.
[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
