Description

Technical Field

[0001] This utility model relates to the field of dry-type grounding transformer technology, and in particular to a resin-insulated amorphous alloy dry-type grounding transformer. Background Technology

[0002] In modern power systems, grounding transformers play an indispensable role. They are mainly used to artificially create a neutral point in three-phase systems where the neutral point is ungrounded or grounded through an arc suppression coil, providing a way for the system to be grounded. This function is crucial for ensuring the safe and stable operation of the power system. By grounding the neutral point through a grounding transformer, the overvoltage level when a single-phase ground fault occurs in the system can be effectively limited, preventing the fault from escalating and preventing electrical equipment from being damaged by overvoltage. At the same time, it provides the relay protection device with the correct action signal, ensuring that the fault can be detected and isolated in a timely manner, thus ensuring the reliability and safety of the power system.

[0003] Existing grounding transformers are difficult to design with direct protection for the transformer body. This makes the equipment susceptible to impacts from foreign objects during operation. Without protective measures, the transformer body may be hit by foreign objects such as stones, causing damage to the outer casing. This can affect the normal operation of internal circuit components and even cause serious faults such as short circuits, thereby reducing the safety and reliability of the equipment operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a resin-insulated amorphous alloy dry-type grounding transformer.

[0005] This utility model is achieved by the following technical solution: a resin-insulated amorphous alloy dry-type grounding transformer, including a support mechanism, a main body mechanism is provided on the top of the support mechanism, and protective mechanisms are provided on both sides of the main body mechanism;

[0006] The support mechanism includes a connecting plate, with support blocks fixedly connected to both sides of the connecting plate, a first support plate fixedly connected to the top of the support blocks, a connecting column fixedly connected to the top of the first support plate, and a second support plate fixedly connected to the top of the connecting column.

[0007] As a further improvement to the above solution, the support blocks are symmetrically distributed through connecting plates, and there are two support blocks.

[0008] The above technical solution provides support for the entire grounding transformer through the set support mechanism. The symmetrically distributed support blocks on both sides of the connecting plate can evenly distribute the weight of the grounding transformer body, avoiding tilting or swaying due to uneven force. The set first support plate and connecting column can further enhance the strength and stability of the support structure, enabling the grounding transformer to maintain good stability during operation, thereby extending the service life of the equipment.

[0009] As a further improvement to the above solution, the main structure includes a body, a top plate is fixedly connected to the top of the body, a fixing pile is fixedly connected to the top of the top plate, and an insulator is sleeved on the surface of the fixing pile.

[0010] As a further improvement to the above solution, a fixing plate is fixedly connected to both sides of the machine body, and a protective frame is fixedly connected to the side of the fixing plate away from the machine body. A groove is opened on one side of the protective frame, and a protective plate is fixedly connected in the groove.

[0011] The above technical solution, through the main structure and the protective frame and plate, directly protects the machine body. The protective plate effectively blocks the impact of foreign objects, preventing damage to the internal circuit components and thus improving the operational safety and reliability of the equipment.

[0012] As a further improvement to the above solution, the protective mechanism includes a pad, a block fixedly connected to the top of the pad, a baffle fixedly connected to the top of the block, a first fixed shaft fixedly connected to one side of the baffle, a limiting plate sleeved on the surface of the first fixed shaft, and a second fixed shaft sleeved on the side of the limiting plate away from the first fixed shaft.

[0013] As a further improvement to the above solution, a side plate is fixedly connected to the side of the body away from the protective frame, and the side plate is fixedly connected to the second fixed shaft.

[0014] Through the above technical solution, the protective mechanism, and the pads and blocks, the vibration and impact from the ground can be buffered, reducing the impact on the machine body. The limiting plate, through the cooperation of the first and second fixed shafts, can flexibly adjust its position, further enhancing the flexibility and targeting of the protection, and providing more precise protection for the machine body according to actual needs.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides support for the entire grounding transformer through a supporting mechanism.

The first support plate and connecting column further enhance the strength and stability of the supporting structure, ensuring good stability during operation and extending the equipment's service life. The main structure, along with the protective frame and protective plate, directly protects the machine body. The protective plate effectively blocks impacts from external objects, preventing damage to internal circuit components and improving operational safety and reliability.
