[0002] A transformer protective cover is an auxiliary device used in power engineering to protect transformers and maintain their stable operation. It has been widely used in the field of power equipment technology. Existing transformer protective covers are fixed to the outside of the transformer to protect it.

[0003] Currently, a Chinese patent has been published for a transformer protective cover, with publication number CN222421521U. In this disclosed technical solution, by installing a fan, a dust removal box, and a dehumidification box inside the casing, the transformer protective cover can be cooled by clean and dry air during use, preventing external moisture and air containing impurities from entering and causing oxidation and corrosion of the metal components inside the transformer.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides, for example Figure 1-3 The protective device for a transformer shown includes a protective cover 1 and a rain cover 9. A heat dissipation hole is provided on one side of the protective cover 1. A housing 2 is fixedly connected to the top of the protective cover 1. Two fans 3 are installed inside the housing 2. The output end of the fans 3 is connected to an air outlet pipe 4. One end of the air outlet pipe 4 is connected to the top of the protective cover 1. The input end of the fans 3 is connected to an air inlet pipe 5. A switch door is provided on the right side of the protective cover 1. The transformer body is located inside the protective cover 1.

[0025] A dehumidifier box 6 is installed through the inner side of the housing 2. An installation port for the dehumidifier box 6 is provided on one side of the housing 2. A handle is provided on one side of the dehumidifier box 6 for easy removal from the housing 2 to replace the desiccant. The desiccant is placed inside the dehumidifier box 6, which absorbs moisture from the air. A filter plate is located on the left side of the dehumidifier box 6, and two air outlet filter holes are provided on the right side of the dehumidifier box 6 that abut against the air inlet pipe 5. A limiting block 13 is fixedly connected to the inner wall of the housing 2. The surface of 13 abuts against the left side of the dehumidification box 6. The limiting block 13 can ensure the stability of the dehumidification box 6 inside the shell 2. One end of the air inlet pipe 5 is made of rubber to ensure the abutment stability between the air inlet pipe 5 and the dehumidification box 6 and to ensure the suction effect of the fan 3. A dustproof net 7 is fixedly connected to the left side of the shell 2. A water-blocking block 8 is fixedly connected to the inside of the shell 2 and to the right of the dustproof net 7. A gap is provided between the top of the water-blocking block 8 and the top of the inner wall of the shell 2. One side of the inner wall of the water-blocking block 8 is an inclined surface.

[0026] The rain cover 9 is set at an angle, and the bottom of the rain cover 9 is connected to the top of the protective cover 1 by two fixing rods. The rain cover 9 is fixedly connected to the top of the protective cover 1, and a U-shaped water collection trough 10 is opened on the top of the rain cover 9. The bottom of the U-shaped water collection trough 10 is connected to a branch pipe 11. In order to prevent the branch pipe 11 from being blocked, a filter screen mechanism can also be installed at the top of the branch pipe 11. The bottom end of the branch pipe 11 abuts against the top of the dustproof net 7. A drainage trough communicating with the U-shaped water collection trough 10 is opened on the left side of the rain cover 9, so that excess rainwater can be drained away in time. A water baffle 12 is fixedly connected to the left side of the protective cover 1 and at the bottom of the dustproof net 7. The water baffle 12 can block the sewage from cleaning the blockage.

[0027] The implementation principle of a protective device for transformers in this application embodiment is as follows: When it is raining, rainwater falls on the rain cover 9, is collected by the U-shaped water collection trough 10, and falls on the dustproof net 7 through the branch pipe 11. The blocked dust is softened and washed by the rainwater, which clears the blockage of the dustproof net 7. At the same time, the washed rainwater is restricted by the water-blocking block 8 and then flows out from the left side of the housing 2 through the dustproof net 7.

[0028] Even in non-rainy weather, the rain cover 9 can be cleaned by rinsing it with water.
