Description

Technical Field

[0001] The present invention belongs to the technical field of electrical equipment testing, and in particular relates to a device for testing an ATS conversion mechanism and a method for using the same. Background Art

[0002] Electricity is an indispensable form of energy in today's industrial, commercial, and residential life. For example, data centers require a continuous and stable power supply to ensure the normal operation of servers and avoid data loss. Hospital life support systems and operating room equipment also rely on uninterrupted power supply. Once the power supply is interrupted, it can lead to serious consequences such as production stagnation, business losses, and even endangerment of life. The ATS (automatic transfer switch) switching mechanism is a key device to ensure the continuity of power supply. It can quickly switch the load to the backup power source when the main power fails, ensuring an uninterrupted power supply.

[0003] When testing the reliability of ATS, the traditional testing method mainly relies on connecting related components through wires to perform various test operations. This test method based on wire connection has problems that cannot be ignored. During the test process, the connection stability of the interface line has a direct and critical impact on the accuracy of the entire test. Since the test device and ATS are connected by many wires, in the actual operating environment, the interface line connection may become loose due to slight vibrations, movement of the equipment or natural loosening during a long test process. Once the interface line connection is loose, it will have an adverse effect on signal transmission. The test of the ATS conversion mechanism requires accurate signal transmission to judge its reliability. Loose interfaces may cause signal interruption, signal attenuation or signal interference, and cannot truly reflect the reliability of the ATS. Summary of the Invention

[0007] As a further solution of the present invention: the number of the conversion brackets is three, and the sizes of the three conversion brackets are designed in an incremental manner. The connecting sleeves at the four corners of the three conversion brackets from low to high correspond to the positions of the conductive columns at both ends of the three commonly used power supplies and three backup power supplies from small to large, respectively, and the size of the connecting columns is adapted to the size of the conductive slots.

[0008] As a further solution of the present invention: a conversion mechanism is fixedly installed above the base plate, and the conversion mechanism includes a mounting bracket, and three adjusting screws are rotatably connected between the inner walls of the mounting bracket, the three adjusting screws are on the same horizontal line, and the outer walls of the three adjusting screws are respectively threadedly connected to three adjusting brackets, and the three adjusting brackets are respectively connected to one end of the three conversion brackets.

The number of the indicator lights is six, and the positions of the six indicator lights correspond to the positions of three normal power supplies and three backup power supplies respectively.

[0013] A method for using an ATS conversion mechanism testing device, the method comprising the following steps:

[0014] When testing the ATS conversion mechanism, connect the connected lines to the connection slots. At this time, the three conversion brackets are located in the center of the three corresponding normal power supplies and three backup power supplies. The normal power supplies and backup power supplies are not powered. When a certain connection slot needs to be powered, the control power drives the corresponding adjustment screw to rotate. During the rotation of the adjustment screw, the adjustment bracket drives the conversion bracket to move horizontally. The horizontal movement of the conversion bracket drives a set of connecting sleeves below it to be connected to the conductive posts at both ends of the normal power supply. At the same time, the connecting posts in the connecting sleeves are inserted into the conductive slots.

[0015] When the connecting column is inserted into the conductive slot, the guide head at the end of the connecting column is squeezed by the conductive slot, and the guide head drives the sliding column to slide at the end of the connecting column. During the sliding process of the sliding column, the driving tooth plate is driven by the baffle to move between the two fixed plates on one side of the support plate, and the driving tooth plate drives the two linked tooth plates engaged with it to rotate. The two linked tooth plates drive the two clamping plates to rotate on one side of the support plate, open, and respectively pass through the two empty slots and then clamp into the conductive slot. The commonly used power supply transmits current to the conversion bracket through the conductive column and the conductive slot, and transmits current to the connecting power supply through the line in the conversion bracket. The connecting power supply then transmits current to the corresponding connecting slot through the connecting wires.

[0016] When it is necessary to switch between the normal power supply and the backup power supply, the sensor monitors the position of the adjustment bracket above the mounting bracket and drives the corresponding adjustment screw to rotate by controlling the power supply. The rotation of the adjustment screw drives the conversion bracket to move toward the backup power supply again through the adjustment bracket. During the movement of the conversion bracket, the two connecting sleeves below it are separated from the normal power supply, and the connecting sleeve on the other side of the conversion bracket is connected to the backup power supply corresponding to the normal power supply, so that the backup power supply supplies power to the connected power supply, and the device is used.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, a stabilizing mechanism is provided. When the device is used, the adjusting screw drives the conversion bracket to switch between the corresponding two common power supplies and the backup power supply. During the switching process, when the two connecting sleeves of the same group are sleeved on the conductive posts at both ends of the common power supply or the backup power supply, the connecting posts in the connecting sleeves will be inserted into the conductive slots. When the connecting posts are inserted into the connecting slots, the guide heads at the ends of the connecting posts are squeezed, and the guide heads drive the sliding posts to slide toward the inside of the connecting posts at the ends of the connecting posts. During the sliding process, the sliding posts drive the driving tooth plates to slide in the two fixed plates on one side of the support plate through the baffle. During the sliding process, the driving tooth plates drive the two clamping plates to rotate and open on one side of the support plate through the two linkage tooth plates. During the rotation and opening process, the two clamping plates pass through the two empty slots and are clamped in the conductive slots. In this way, the connection between the conversion bracket and the common power supply or the backup power supply line is reinforced, effectively preventing the line from loosening and falling during the test, thereby improving the accuracy of the test and ensuring the reliability and authenticity of the ATS reliability test results.

[0019] 2. In the present invention, a conversion mechanism and a conversion bracket are provided. When the device is used, the three conversion brackets are located between the three common power supplies and the three backup power supplies respectively. At this time, the connecting sleeve below the conversion bracket is not connected to the conductive column. When a certain connection slot needs to be connected, the control power supply drives one of the adjusting screws to rotate independently. During the rotation of the adjusting screw, the conversion bracket is driven to move horizontally through the adjusting bracket threadedly connected to it. The sensor monitors the position of the adjusting bracket, and the conversion bracket drives the connecting sleeve below to be connected to the outside of the conductive column of one of the common power supplies for conduction. During the conduction process, when it is necessary to convert the common power supply to the backup power supply, under the monitoring of the sensor, the control power supply drives one of the adjusting screws to rotate, and the adjusting screw drives the conversion bracket to the other side through the adjusting bracket. When the two connecting sleeves of the conversion bracket are disconnected from the common power supply, the two connecting sleeves at the other end are connected to the outside of the conductive columns at both ends of the backup power supply opposite to it. In this way, the switching between the common power supply and the backup power supply can be completed quickly, and the switching efficiency is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

The number of the conversion brackets 5 is three, and the sizes of the three conversion brackets 5 are incrementally designed. The connecting sleeves 6 at the four corners of the three conversion brackets 5 from low to high correspond to the positions of the conductive columns 8 at both ends of the three common power supplies 3 and the three backup power supplies 4 from small to large, respectively. Through the cooperation between the conversion bracket 5 and the common power supply 3 and the backup power supply 4, this one-to-one correspondence makes the conversion process of the common power supply 3 and the backup power supply 4 more orderly and accurate. At the same time, the conversion bracket 5 with an incremental size design can adapt to common power supplies 3 and backup power supplies 4 of different sizes, ensuring that each common power supply 3 and backup power supply 4 can be effectively cooperated with the appropriate conversion bracket 5, and the size of the connecting column 701 is adapted to the size of the conductive slot 9;

Due to the provision of the conversion bracket 5, the conversion bracket 5 can accurately guide the conversion path of the normal power supply 3 and the backup power supply 4 when the normal power supply 3 and the backup power supply 4 need to be switched under different test requirements, thereby ensuring the high efficiency and accuracy of the conversion between the normal power supply 3 and the backup power supply 4, and reducing the influence of unstable factors on the test results during the conversion process between the normal power supply 3 and the backup power supply 4. The directions of the two groups of connecting sleeves 6 are opposite, and a stabilizing mechanism 7 is fixedly installed between the inner walls of the connecting sleeves 6.

The protruding parts on both sides of the support plate 707 are rotatably connected to two clamping plates 7010. The two clamping plates 7010 face opposite directions and correspond to the positions of the two empty slots 702 respectively. Two linkage tooth plates 7011 are fixedly installed on the opposite sides of the two clamping plates 7010. The two linkage tooth plates 7011 are located on both sides of the driving tooth plate 709 and mesh with the driving tooth plate 709;

The outer walls of the three adjusting screws 1002 are respectively threadedly connected with three adjusting brackets 1003. The three adjusting brackets 1003 are respectively connected to one end of the three conversion brackets 5. Through the cooperation between the adjusting screws 1002 and the adjusting brackets 1003, the adjusting screws 1002 rotate and drive the conversion bracket 5 to move through the adjusting bracket 1003. In this way, the stability of the conversion bracket 5 when switching between the normal power supply 3 and the backup power supply 4 is guaranteed.

Due to the provision of the limit rods 1005, the limit rods 1005 can limit the moving direction of the adjusting bracket 1003 to prevent it from offsetting or rotating during the adjustment process, thereby ensuring the accuracy of the adjustment. A sensor 1006 is fixedly installed at the top of the mounting bracket 1001 at its center position. Due to the provision of the sensor 1006, the sensor 1006 can monitor the relevant parameters of the conversion mechanism 10, such as position, status, etc. in real time, provide accurate data feedback for the test process, and accurately adjust the position of the conversion bracket 5 to adapt to different test requirements, such as the distance between the conversion bracket 5 and the normal power supply 3 and the backup power supply 4;

[0034] A method for using an ATS conversion mechanism testing device, the method comprising the following steps:

[0035] When testing the ATS conversion mechanism 10, the connected lines are connected to the connection slots 14. At this time, the three conversion brackets 5 are located in the center of the three corresponding normal power sources 3 and three backup power sources 4. When a certain connection slot 14 needs to be powered, the control power supply 1004 drives the corresponding adjustment screw 1002 to rotate. During the rotation of the adjustment screw 1002, the adjustment bracket 1003 drives the conversion bracket 5 to move horizontally. The horizontal movement of the conversion bracket 5 drives a set of connecting sleeves 6 below it to be connected to the outside of the conductive posts 8 at both ends of the normal power source 3. At the same time, the connecting posts 701 in the connecting sleeves 6 are inserted into the conductive slots 9.

[0036] When the connecting column 701 is inserted into the conductive slot 9, the guide head 704 at the end of the connecting column 701 is squeezed by the conductive slot 9, and the guide head 704 drives the sliding column 703 to slide on the end of the connecting column 701. During the sliding process of the sliding column 703, the baffle 705 drives the driving tooth plate 709 to move between the two fixed plates 708 on one side of the support plate 707, and the driving tooth plate 709 drives the two linked tooth plates 7011 engaged with it to rotate. The two linked tooth plates 7011 drive the two clamping plates 7010 to rotate and open on one side of the support plate 707, respectively passing through the two empty slots 702 and then clamped in the conductive slot 9. The common power supply 3 transmits current to the conversion bracket 5 through the conductive column 8 and the conductive slot 9, and transmits current to the connection power supply 11 through the line in the conversion bracket 5. The connection power supply 11 then transmits current to the corresponding connection slot 14 through the connecting wire 12;

[0037] When it is necessary to switch between the normal power supply 3 and the backup power supply 4, the sensor 1006 monitors the position of the adjustment bracket 1003 above the mounting bracket 1001, and drives the corresponding adjustment screw 1002 to rotate by controlling the power supply 1004. The adjustment screw 1002 rotates through the adjustment bracket 1003 to drive the conversion bracket 5 to move toward the backup power supply 4 again. During the movement of the conversion bracket 5, the two connecting sleeves 6 below it are disengaged from the normal power supply 3, and the connecting sleeve 6 on the other side of the conversion bracket 5 is connected to the outside of the backup power supply 4 corresponding to the normal power supply 3, so that the backup power supply 4 supplies power to the connection power supply 11, and the device is used.

Three connection slots (14) are fixedly installed on one side of the protective shell (13), and three connection wires (12) are respectively connected to the three connection slots (14).

8. The device for testing an ATS conversion mechanism according to claim 1, characterized in that: The bottom of the base plate (1) is provided with a plurality of heat dissipation slots (15), and a plurality of indicator lights (16) are fixedly mounted above the base plate (1). The number of the indicator lights (16) is six, and the positions of the six indicator lights (16) respectively correspond to the positions of the three normal power supplies (3) and the three backup power supplies (4).

9. A method for using an ATS conversion mechanism testing device, according to any one of claims 1 to 8, characterized in that: The method of use comprises the following steps: When the ATS conversion mechanism is tested, the connected line is connected to the connection slot (14). At this time, the three conversion brackets (5) are located at the center of the three corresponding normal power sources (3) and three backup power sources (4). The normal power sources (3) and the backup power sources (4) are not powered. When a certain connection slot (14) needs to be powered, the control power supply (1004) drives the corresponding adjustment screw (1002) to rotate. During the rotation of the adjustment screw (1002), the conversion bracket (5) is driven to move horizontally through the adjustment bracket (1003). The horizontal movement of the conversion bracket (5) drives a group of connecting sleeves (6) below it to be connected to the outside of the conductive pillars (8) at both ends of the normal power source (3). At the same time, the connecting pillars (701) in the connecting sleeves (6) are plugged into the conductive slots (9). When the connecting column (701) is inserted into the conductive slot (9), the guide head (704) at the end of the connecting column (701) is squeezed by the conductive slot (9), and the guide head (704) drives the sliding column (703) to slide at the end of the connecting column (701). During the sliding process of the sliding column (703), the baffle (705) drives the driving tooth plate (709) to move between the two fixed plates (708) on one side of the support plate (707), and the driving tooth plate (709) drives the two linked tooth plates (7011) engaged with it to rotate. The two linkage tooth plates (7011) drive the two clamping plates (7010) to rotate and open on one side of the support plate (707) and respectively penetrate the two empty slots (702) and then clamp into the conductive slot (9). The common power supply (3) transmits the current to the conversion bracket (5) through the conductive column (8) and the conductive slot (9), and transmits the current to the connection power supply (11) through the line in the conversion bracket (5). The connection power supply (11) then transmits the current to the corresponding connection slot (14) through the connecting wire (12); When the normal power supply (3) and the backup power supply (4) need to be switched, the sensor (1006) monitors the position of the adjustment bracket (1003) above the mounting bracket (1001) and drives the corresponding adjustment screw (1002) to rotate by controlling the power supply (1004). The adjustment screw (1002) rotates and drives the conversion bracket (5) to move toward the backup power supply (4) again through the adjustment bracket (1003). During the movement of the conversion bracket (5), the two connecting sleeves (6) below it are separated from the normal power supply (3). The connecting sleeve (6) on the other side of the conversion bracket (5) is connected to the outside of the backup power supply (4) corresponding to the normal power supply (3), so that the backup power supply (4) supplies power to the connection power supply (11), and the device is used.
