[0002] Dry-type transformers are widely used in places like local lighting, high-rise buildings, airports, and dock machinery. Simply put, dry-type transformers are transformers whose cores and windings are not immersed in insulating oil. Cooling methods include natural air cooling and forced air cooling. With natural air cooling, the transformer can operate continuously at rated capacity for extended periods. They are suitable for intermittent overload operation or emergency overload conditions. However, due to the significant load loss and impedance voltage increase during overload, resulting in uneconomical operation, prolonged continuous overload operation should be avoided to prevent overload.

[0003] Dry-type transformers can be overloaded during operation. Traditional dry-type transformers can be damaged or even cause fires and other safety incidents if overloaded. To ensure safe operation, personnel must regularly check the operating status of dry-type transformers and take immediate protective measures if an overload is detected.

[0025] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0026] A dry-type transformer with an overload protection structure according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, a dry-type transformer 1 with an overload protection structure according to an embodiment of the present invention includes: a transformer 1 and an overload protection mechanism 4.

[0028] The overload protection mechanism 4 includes a control box 41 , a circuit breaker 42 and a heat dissipation component 43 .

[0029] The control box 41 is arranged outside the transformer 1 , the circuit breaker 42 is arranged on the control box 41 , and the heat dissipation component 43 is arranged at the bottom of the transformer 1 .

[0030] Specifically, when the transformer 1 is overloaded, the circuit breaker 42 can quickly cut off the circuit, thereby preventing the transformer 1 from being damaged due to overload. The heat dissipation component 43 can effectively dissipate the heat generated by the transformer 1 during operation, ensuring the stable operation of the transformer 1.

[0031] In one embodiment of the present application, Figure 2 As shown, the heat dissipation assembly 43 includes a water pump 431 , a water delivery pipe 432 , a water tank 433 and a water delivery pipe 434 .

[0032] Among them, the water pump 431 is arranged outside the transformer 1, one end of the water supply pipe 432 is connected to the input end of the water pump 431, the water tank 433 is connected to the other end of the water supply pipe 432, one end of the water transport pipe 434 is connected to the output end of the water pump 431, and the other end of the water transport pipe 434 is connected to the water tank 433.

[0033] Specifically, when the transformer 1 needs to dissipate heat, the water pump 431 is started, and the water in the water tank 433 is sucked in through the water pipe 432, and then the water is transported to the heat dissipation part of the transformer 1 through the water pipe 434 for heat dissipation. The water after heat dissipation flows back to the water tank 433, forming a circulating heat dissipation system, thereby improving the heat dissipation efficiency and ensuring the normal operation of the transformer 1.

[0034] In one embodiment of the present application, Figure 1 As shown, the transformer 1 is provided with iron clamps 2 , and are symmetrically arranged with respect to the long central axis of the upper wall of the transformer 1 .

[0035] It is understandable that the arrangement of the iron clamps 2 facilitates the fixing and installation of the transformer 1, thereby improving the stability and safety of the transformer 1. The symmetrical arrangement of the iron clamps 2 also ensures the balance of the transformer 1 during the fixing process, thereby avoiding potential safety hazards caused by unstable fixing.

[0036] In one embodiment of the present application, Figure 2 As shown, a fixing frame 5 is provided at the bottom of the transformer 1 .

[0037] It can be understood that, by providing the fixing frame 5 , the stability of the transformer 1 during placement can be further improved, thereby preventing the transformer 1 from tipping over or being damaged due to unstable placement.

[0038] In one embodiment of the present application, Figure 3 As shown, a moisture-proof mechanism 6 is provided at the bottom of the transformer 1 .

[0039] The moisture-proof mechanism 6 includes a moisture-proof pad 61 , a lifting frame 62 and a heat dissipation net 63 .

[0040] The moisture-proof pad 61 is arranged at the bottom of the transformer 1 , the lifting frame 62 is arranged at the bottom of the transformer 1 , and the heat dissipation net 63 is installed inside the moisture-proof pad 61 .

[0041] A fixed shell 64 is provided on the moisture-proof pad 61 , a fan 65 is provided inside the fixed shell 64 , and a dustproof net 66 is installed inside the fixed shell 64 .

[0042] Specifically, when the transformer 1 is used daily, the transformer 1 is first raised by the lifting frame 62 to form a certain distance between the bottom of the transformer 1 and the ground. In this way, the moisture-proof pad 61 can effectively isolate the moisture from the ground and prevent the transformer 1 from malfunctioning due to moisture. The setting of the heat dissipation net 63 can further improve the heat dissipation efficiency of the transformer 1 and ensure the normal operation of the transformer 1. The fan 65 is started, and the airflow generated by the fan 65 passes through the heat dissipation net 63 to dissipate heat from the bottom of the transformer 1 and circulate air, thereby further preventing moisture accumulation. The setting of the dustproof net 66 can effectively prevent dust from entering the interior of the fixed shell 64.

[0043] In one embodiment of the present application, Figure 4 As shown, an explosion-proof component 7 is provided outside the transformer 1 .

[0044] The explosion-proof assembly 7 includes a fireproof plate 71 , an explosion-proof plate 72 , a pressure gauge 73 and an air relief valve 74 .

[0045] The fireproof plate 71 is arranged on the outer wall of the transformer 1, and the explosion-proof plate 72 is installed on the outer wall of the fireproof plate 71. The iron clamp 2 is provided with an air release valve 74 and a pressure gauge 73.

[0046] Specifically, if a fault occurs within transformer 1, causing internal pressure to rise, pressure gauge 73 can monitor the pressure inside transformer 1 in real time. When the pressure exceeds a safe range, relief valve 74 can automatically open to release the excessive internal pressure and prevent an explosion in transformer 1. Fireproof panels 71 and explosion-proof panels 72 installed on the exterior of transformer 1 can effectively block flames and debris from an explosion, further enhancing the safety of transformer 1.

[0047] In one embodiment of the present application, Figure 1 As shown, a bracket 3 is provided at the bottom of the transformer 1 and is symmetrically arranged with respect to the central axis of the transformer 1 .

[0048] It can be understood that, by disposing the bracket 3 , the support stability of the transformer 1 can be further enhanced, thereby ensuring the safety and reliability of the transformer 1 during operation.

[0049] In one embodiment of the present application, Figure 1 As shown, fixing plates 8 are equidistantly arranged on the iron clamp 2 .

[0050] It can be understood that by setting the fixing plate 8, the fixing points of the iron clamp 2 can be further increased, the stability and firmness of the transformer 1 during the fixing process can be improved, and the transformer 1 can be prevented from shaking or falling off during operation, thereby ensuring the safe operation of the transformer 1.

[0051] Working Principle: When transformer 1 is operating, circuit breaker 42 in the overload protection mechanism 4 continuously monitors the current flowing through transformer 1. If the current exceeds a preset safety range, i.e., if transformer 1 is overloaded, circuit breaker 42 rapidly disconnects the circuit to prevent the current from increasing further, effectively preventing damage or safety accidents caused by overload. Simultaneously, water pump 431 in heat dissipation assembly 43 activates, drawing water from water tank 433 via water pipe 432. The water is then transported via water delivery pipe 434 to the heat dissipation area of ​​transformer 1 for dissipation. The cooled water then flows back into water tank 433, forming a circulating heat dissipation system that prevents transformer 1 from overheating during operation and ensures stable operation. Furthermore, moisture-proof mat 61 in moisture-proof mechanism 6 effectively isolates ground moisture, preventing transformer 1 from getting wet. Heat dissipation screen 63 and fan 65 further enhance heat dissipation efficiency. Dust screen 66 prevents dust from entering the interior of fixed housing 64, maintaining a clean environment. The provision of the explosion-proof component 7 can effectively prevent the occurrence of explosion accidents when a fault occurs inside the transformer 1, thereby further improving the safety of the transformer 1.

[0052] In summary, in an embodiment of the present invention, a dry-type transformer 1 with an overload protection structure, the heat dissipation component 43 can dissipate the generated heat in a timely manner, ensure the safe and stable operation of the transformer 1, and prevent the transformer 1 from being overloaded to a certain extent. When the transformer 1 is overloaded, the circuit breaker 42 on the control box 41 can be used to quickly cut off the circuit.
