Description

Technical Field

[0001] This utility model relates to the technical field of transformers, and in particular to a portable experimental dry-type isolation transformer. Background Technology

[0002] Dry-type isolation transformers are instruments used for voltage isolation transformation and are widely applicable to AC circuits with a frequency of 50Hz to 60Hz and a voltage below 660V. Various input and output voltage levels, connection groups, number and position of adjustment taps (generally ±5%), winding capacity distribution, configuration of secondary single-phase windings, application of rectifier circuits, and whether a casing is required can all be designed and manufactured according to user requirements.

[0003] Dry-type isolation transformers are key laboratory equipment and are widely used in power system testing, precision instrument power supply and electrical isolation. Laboratories often need to adjust the position of the equipment according to the experimental layout. However, traditional transformers are heavy and lack a dedicated moving mechanism, so they need to be moved by forklifts or multiple people, which is inefficient and easily causes the equipment to be damaged.

[0008] A locking mechanism, mounted on the extension, is used to lock the connection between the mounting bracket and the mounting component.

[0009] Two adjustment mechanisms are installed on two mounting brackets respectively. The two adjustment mechanisms are used to support the dry-type isolation transformer on the two mounting brackets.

[0010] The traction mechanism, mounted on the mounting component, is used to move the dry-type isolation transformer.

[0011] Furthermore, the locking mechanism includes:

[0012] The movable part is slidably installed in the inner cavity of the extension part, and the movable part is provided with two positioning pins. The two positioning pins pass through the through holes of the extension part respectively, and the positioning pins are engaged with the connection holes of the mounting bracket for insertion and removal installation.

[0014] A drive rod is mounted on the moving part through the inner hole of the mounting part, and a pedal is mounted on the end of the drive rod.

[0015] Preferably, when both locating pins are engaged with the two connecting holes of the mounting bracket, the connection between the mounting bracket and the mounting component is locked.

[0016] When a locating pin engages with a connecting hole of the mounting bracket, the mounting bracket and mounting components rotate around the locating pin, which facilitates the mounting bracket moving away from the dry-type isolation transformer.

[0017] Furthermore, the regulatory body includes:

[0018] A threaded tube is rotatably installed in the shaft hole of the mounting bracket, and a threaded post is installed inside the threaded tube. At least two threaded tubes are provided.

Detailed Implementation

[0045] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0046] This utility model relates to a portable experimental dry-type isolation transformer, such as... Figures 1 to 7 As shown, it includes:

[0047] Mounting component 1 is independently fixed and serves as the basic support for the entire device. It has sufficient strength and stability to support all components, and extension components 2 are symmetrically arranged at both ends of mounting component 1.

[0048] Two mounting brackets 3 are slidably mounted on two extension pieces 2 respectively, and two positioning holes are provided at the sliding connection between the mounting bracket 3 and the extension piece 2. The two mounting brackets 3 are connected by a fixing mechanism 4. The mounting bracket 3 is provided with a set of caster wheels 5 to facilitate the movement of the whole device.

[0049] The locking mechanism 6 is installed on the extension 2. The locking mechanism 6 is used to lock the connection position between the mounting bracket 3 and the mounting part 1 to ensure the stability of the dry isolation transformer 8 during use.

[0050] Two adjustment mechanisms 7 are respectively installed on two mounting brackets 3. The two adjustment mechanisms 7 are used to support the dry isolation transformer 8 on the two mounting brackets 3, so as to facilitate the disassembly and assembly of the dry isolation transformer 8.

[0051] The traction mechanism 9 is installed on the mounting component 1 and is used to move the dry-type isolation transformer 8.

[0052] The working principle of this device is as follows:

[0053] First, adjust the position of the mounting bracket 3 on the extension 2 according to actual needs, and use the locking mechanism 6 to lock them in the appropriate position to ensure that the mounting bracket 3 will not move accidentally during use. Place the dry isolation transformer 8 on the two mounting brackets 3 through the adjustment mechanism 7. When it is difficult to move the entire device, use the fuma wheel set 5 and the traction mechanism 9 to make the device easily move to the designated position inside the laboratory. After reaching the target position, use the locking mechanism of the fuma wheel 5 for support and leveling to ensure that the dry isolation transformer 8 is stably and accurately placed in the new working position.

[0054] Mounting component 1 serves as the basic support, providing reliable load-bearing capacity for the entire device thanks to its high strength and stability. The symmetrically arranged extensions 2 at both ends create conditions for the sliding installation of mounting frames 3. The two mounting frames 3 are slidably installed on the extensions 2, and the spacing can be flexibly adjusted according to actual needs. The fixing mechanism 4 achieves a stable connection between the two mounting frames 3. At the same time, the fuma wheel set 5 on the mounting frame 3 gives the device convenient mobility, meeting the needs of multiple laboratory scenarios. The locking mechanism 6 is installed on the extensions 2, which can accurately lock the connection position between the mounting frame 3 and the mounting component 1, effectively preventing the dry-type isolation transformer 8 from shaking and shifting during use, ensuring safe and stable operation. The two adjusting mechanisms 7 are installed on the mounting frame 3, simplifying the disassembly and assembly process of the dry-type isolation transformer 8 and improving equipment maintenance efficiency. The traction mechanism 9 is installed on the mounting component 1, making it convenient for operators to pull the dry-type isolation transformer 8 to move. Together with the fuma wheel set 5, it makes the movement of the device in the laboratory environment easier and more efficient, significantly improving the flexibility and convenience of using the experimental dry-type isolation transformer.

[0055] As a preferred option, such as Figures 1 to 6 As shown, the locking mechanism 6 includes:

[0056] The movable part 61 is slidably installed in the inner cavity of the extension 2, and the movable part 61 is provided with two positioning pins 62. The two positioning pins 62 pass through the through hole of the extension 2 respectively, and the positioning pins 62 are engaged with the connection hole of the mounting bracket 3 for insertion and removal installation.

[0057] The first spring 63 has one end mounted on the movable part 61 and the other end mounted on the inner wall of the mounting part 1;

[0058] The drive rod 64 is installed on the movable part 61 through the inner hole of the mounting part 1, and a pedal 65 is installed at the end of the drive rod 64;

[0059] When both positioning pins 62 are engaged with the two connecting holes of the mounting bracket 3, the connection between the mounting bracket 3 and the mounting component 1 is locked.

[0060] When a locating pin 62 engages with a connecting hole of the mounting bracket 3, the mounting bracket 3 and the mounting component 1 rotate around the locating pin 62, which facilitates the mounting bracket 3 moving away from the dry-type isolation transformer 8.

[0061] When the two locating pins 62 are inserted into the connecting holes of the mounting bracket 3, a double-point positioning is formed. Working together with the extension 2 and the fixing mechanism 4, the displacement of the mounting bracket 3 is firmly restricted, ensuring the stability of the dry-type isolation transformer 8 during operation. The first spring 63 provides elastic restoring force, so that the locating pins 62 can automatically return to their original position after unlocking, ensuring the continuity of the mechanism operation. By stepping on the pedal 65, the drive rod 64 is driven to push the moving part 61 to slide, realizing the quick insertion and removal of the locating pins 62. The operation is convenient and labor-saving. The single locating pin 62 working mode allows the mounting bracket 3 to rotate around the locating pin 62, making it easier for the mounting bracket 3 to move away from the dry-type isolation transformer 8, providing more operating space for the disassembly, assembly, and maintenance of the equipment, and greatly improving the safety, convenience, and maintenance efficiency of the device.

[0062] As a preferred option, such as Figures 1 to 5 As shown, the adjustment mechanism 7 includes:

[0063] The threaded tube 71 is rotatably installed in the shaft hole of the mounting bracket 3, and a threaded post 72 is installed inside the threaded tube 71. At least two threaded tubes 71 are provided.

[0064] A support frame 73 is mounted on at least two threaded posts 72. The support frame 73 is used to support the dry-type isolation transformer 8.

[0065] The drive mechanism 74 is mounted on the mounting bracket 3 and is used to provide rotational power to the threaded tube 71.

[0066] The threaded tube 71 is rotatably installed in the shaft hole of the mounting bracket 3 and cooperates with the internal threaded column 72. Utilizing the thread transmission principle, the drive mechanism 74 provides rotational power, which can accurately and stably adjust the lifting height of the threaded column 72. The setting of at least two threaded tubes 71 and threaded columns 72, together with the support bracket 73, can evenly distribute the weight of the dry-type isolation transformer 8 and ensure the stability of the equipment support. The operator can easily control the rotation of the threaded tube 71 through the drive mechanism 74, thereby quickly adjusting the height of the support bracket 73, which facilitates the accurate installation and disassembly of the dry-type isolation transformer 8, reduces the intensity of manual operation, and improves the accuracy of equipment installation and maintenance efficiency.

[0067] As a preferred option, such as Figures 1 to 5 As shown, the drive mechanism 74 includes:

[0068] A fixing bracket 74a is mounted on the mounting bracket 3, and a worm gear 74b is rotatably mounted on the fixing bracket 74a;

[0069] Worm gear 74c is coaxially mounted on threaded tube 71 and meshes with worm 74b.

[0070] Joystick 74d is mounted on worm gear 74b;

[0071] The fixed frame 74a is installed on the mounting frame 3, providing stable support for the worm gear 74b and ensuring stable and reliable transmission. The worm gear 74b is meshed with the worm wheel 74c, which is coaxially mounted on the threaded tube 71. Utilizing the high precision and large transmission ratio characteristics of the worm gear transmission, the operating force of the rocker arm 74d can be effectively converted into the rotational power of the threaded tube 71, realizing precise control of the lifting and lowering of the threaded column 72. The operator only needs to easily shake the rocker arm 74d to drive the worm gear 74b to rotate, thereby driving the worm wheel 74c and the threaded tube 71, making it convenient and quick to adjust the height of the support frame 73. At the same time, the self-locking function of the worm gear transmission can prevent the threaded tube 71 from rotating on its own under the gravity of the dry-type isolation transformer 8, ensuring the stability of the equipment support height and significantly improving the convenience, safety and adjustment accuracy of the dry-type isolation transformer 8 during disassembly and assembly.

[0072] As a preferred option, such as Figures 1 to 4 As shown, the traction mechanism 9 includes:

[0073] Connector 91 is mounted on mounting part 1, and is rotatably mounted on assembly part 92;

[0074] A pull rod 93 is mounted on the assembly 92, and a pull handle 94 is mounted on the pull rod 93;

[0075] The positioning mechanism 95 is installed on the assembly 92 and is used to lock the installation angle between the assembly 92 and the connector 91.

[0076] The connector 91 is installed on the mounting part 1, providing a stable base for the rotation of the assembly 92, allowing the assembly 92 to adjust its angle according to actual traction needs. The traction rod 93 installed on the assembly 92 works in conjunction with the pull handle 94 to facilitate the operator to apply force for traction. It conforms to ergonomic design and effectively reduces operator fatigue. The positioning mechanism 95 can accurately lock the installation angle between the assembly 92 and the connector 91, ensuring that the traction rod 93 remains stable during non-traction processes and reducing the space occupied.

[0077] As a preferred option, such as Figures 1 to 4 As shown, the positioning mechanism 95 includes:

[0078] Positioning component 95a is slidably installed inside the groove of assembly 92, and positioning component 95a is connected to the teeth on connector 91.

[0079] Extension rod 95b is mounted on positioning member 95a, and extension rod 95b is configured as a T-shaped structure;

[0080] The second spring 95c is mounted on the positioning part 95a at one end and on the cavity wall of the assembly 92 at the other end.

[0081] The positioning component 95a is slidably installed inside the groove of the assembly 92 and engages with the teeth on the connector 91. This allows for precise locking of the relative angle between the assembly 92 and the connector 91, ensuring that the angle of the traction rod 93 remains stable when not under traction. The extension rod 95b is installed on the positioning component 95a and has a T-shaped structure, providing a convenient point of force application for the operator. This allows for easy control of the sliding of the positioning component 95a by pulling the extension rod 95b, enabling quick unlocking and locking operations and greatly improving the convenience and efficiency of the operation. One end of the second spring 95c is connected to the positioning component 95a, and the other end is fixed to the groove wall of the assembly 92. After the unlocking operation, its elastic restoring force allows the positioning component 95a to automatically reset and quickly re-engage with the teeth of the connector 91, ensuring the continuity and reliability of the angle locking.

[0082] As a preferred option, such as Figures 2 to 7 As shown, the fixing mechanism 4 includes:

[0083] A connecting post 41 is mounted on a mounting bracket 3, and an auxiliary component 42 is rotatably mounted on the connecting post 41;

[0084] Bolt 43 is installed in the threaded hole of another mounting bracket 3 for connection. Bolt 43 is used to fix the auxiliary part 42 to the mounting bracket 3.

[0085] The connecting column 41 is mounted on a mounting bracket 3, providing a base for the auxiliary component 42 to be rotated and installed, allowing the auxiliary component 42 to be flexibly adjusted at the angle. The bolt 43 engages with the threaded hole of another mounting bracket 3 and is used to fix the auxiliary component 42 to the mounting bracket 3. This threaded connection method can provide strong fastening force, firmly connecting the two mounting brackets 3 together, effectively preventing the mounting brackets 3 from being relatively displaced under the gravity of the dry isolation transformer 8 or during the movement of the device, and ensuring the stability of the entire device structure.

[0086] This utility model discloses a portable experimental dry-type isolation transformer. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0087] The above are merely preferred embodiments of this utility model.
