Description

Technical Field

[0001] The invention relates to the technical field of transformer protection, in particular to a main transformer cat-proof device. Background Art

[0002] The main transformer, referred to as the main transformer, is a total step-down transformer mainly used for power transmission and transformation in a unit or substation. It is also the core part of the substation. The transformer is the core equipment of the electric locomotive traction power supply system and is also the key equipment to ensure the safe and stable operation of the traction power supply system. The capacity of the main transformer is generally large and requires high reliability. Although the failure rate of the main transformer is not high, once a failure occurs, it will cause significant losses. At the least, it may cause equipment failure; at worst, it may cause a fire and endanger normal transportation safety. Therefore, it is of great significance to analyze the cause of the transformer failure and take corresponding preventive measures.

[0003] When the main transformer is exposed, cats often jump onto it, which brings great risks to the safe operation of the main transformer and may also cause serious incidents of main transformer short circuit. In addition, when the temperature of the main transformer is too high, the load is too heavy and the temperature rises slowly, which will seriously damage the insulation, shorten the service life or burn the main transformer. Once the critical temperature is exceeded, the transformer will trip. If the transformer continues to operate, it will cause damage, resulting in large-scale power outages. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, and provides a main transformer cat-proof device, which includes an external component 100, including a protective frame 101; and,

[0025] The flip assembly 200 includes a fixing column 201 disposed above the protection frame 101 .

[0026] The external component 100 further includes through slots formed at both ends of the protection frame 101 , and a protection door 101 a is disposed in the through slots.

[0027] Protection nets 101 b are provided at both ends of the protection frame 101 , and a transformer 102 is provided inside the protection frame 101 .

[0028] The protective doors 101a provided at both ends of the protective frame 101 facilitate the entry of maintenance personnel when the transformer 102 needs to be repaired.

[0029] Usage process: When a cat approaches the transformer 102 and climbs into the protective frame 101 through the protective net 101b, the cat will contact the flip assembly 200, and the flip assembly 200 will rotate, so that the cat cannot cross the protective frame 101 and is blocked outside the protective frame 101, thereby preventing the cat from approaching the transformer 102 and causing damage to it.

[0030] Example 2, reference Figure 1 to Figure 2 , which is the second embodiment of the present invention, and provides a main transformer anti-cat device, which includes a flip assembly 200 and a connecting shaft 201a arranged between fixed columns 201, and a first rotating blade 202 is arranged on the outer side of the connecting shaft 201a.

[0031] A second rotating shaft is disposed at the other end of the fixing column 201 , and a second rotating blade 203 is disposed outside the second rotating shaft.

[0032] The fixing columns 201 are arranged around the protection frame 101 .

[0033] The first rotating blade 202 and the second rotating blade 203 are in the shape of blade columns.

[0034] Among them, a 7m x 7m and 2m high frame is built through a protective net 101b with a diameter of 110. The protective net 101b uses a plastic mesh to seal the four facades of the frame. The gap of the protective net 101b is less than 3cm to prevent cats from passing through, and a door is opened on one side of the facade to facilitate people to enter and exit.

[0035] Usage process: through the first rotating leaf 202 and the second rotating leaf 203 that can rotate between the fixed column 201 at the top of the protection frame 101, when a cat climbs to the upper part of the facade of the first rotating leaf 202 or the second rotating leaf 203, because the cat's claws are on the first rotating leaf 202 or the second rotating leaf 203, and the first rotating leaf 202 or the second rotating leaf 203 rotates, it cannot climb over and enter the transformer site, and a short circuit of the main transformer is prevented.

[0036] Example 3, reference Figure 1 to Figure 2 , which is the third embodiment of the present invention, and this embodiment provides a main transformer anti-cat device, which also includes a cooling component 300, the cooling component 300 includes a water storage barrel 301 arranged at one end of the protection frame 101, a drainage pipe 302 is arranged above the water storage barrel 301, and a water pump is arranged at one end of the drainage pipe 302.

[0037] The drainage pipe 302 is connected to the protection net 101b.

[0038] The other end of the drainage pipe 302 is provided with 302a, and the top of the water storage barrel 301 is provided with a water spray head 303a, and one end of the water spray head 303a is provided with a water pumping pipe 303.

[0039] Among them, by placing a water storage barrel 301 in the transformer 102 site, the water storage barrel 301 can be replenished with water through the pumping pipe 303 and the sprinkler head 303a. When the water level is lower than the specified level, it is automatically replenished with water. After it is replenished to the specified height, the water valve is cut off.

[0040] Usage process: by passing the drain pipe 302 through the gap of the protective net 101b and setting 302a, when the temperature of the main transformer is too high and spray cooling is required, start the water pump, and use the water pump to pump the water in the water storage tank 301 into the drain pipe 302, and then 302a on the drain pipe 302 sprays the water to the transformer 102, thereby achieving cooling of the transformer 102.
