Description
Technical Field
The application relates to a protective cabinet, in particular to a transformer protective cabinet capable of preventing water immersion.
Background
The existing transformer is placed in a place, especially a residential building or a commercial office building, and the transformer is placed in a special placement space in the middle of the building or in a special placement space at the bottommost layer under the ground of the building for safety and protection. When the transformer is placed at the lowest layer of the ground, isolation and protection measures are usually provided, so that no influence is caused on pedestrians and objects. However, the conventional transformer is not designed or manufactured with consideration to the safety and reliability of the place, and is not usually used with a buried transformer having good waterproof property due to convenience of maintenance. Therefore, once the basement is filled with water, or the bottommost layer of the basement is irrigated, immeasurable influence is brought to the transformer, and even the transformer is damaged and cannot be used. Particularly, in the rainstorm weather in the south of recent years, there is a problem that the underground garage or basement is immersed in water in some areas, and thus the transformer is damaged due to the immersion in water. Therefore, the transformer commonly used in the prior art has poor waterproof effect and can be damaged due to the water filling of the basement.

In addition, the number of the hanging ropes corresponds to the number of the electric pneumatic scissors one by one. The controller is electrically connected with the electro-pneumatic scissors, and the movement of the electro-pneumatic scissors is controlled by the controller, so that the hanging rope is cut off. When the hanging rope is sheared, the sealing plate 20 falls down and falls into the limit groove M under the action of gravity.
The application relates to an operating principle of an exemplary water-immersion-proof transformer protective cabinet, which comprises the following steps:
when the outer liquid level meter detects that the liquid level is within a set threshold range, the controller controls the electric pneumatic scissors to work and cuts off the hanging rope; meanwhile, the controller controls the first magnetic assembly 81, the upper electromagnet 41, the lower electromagnet 42, and the drain pump 51 to be energized.
When the sealing plate 20 falls down and enters the limit groove M downwards along the gravity, the front side and the rear side of the sealing plate are respectively limited by the limit frame 30 and the cabinet body 10, and meanwhile, the gap between the sealing plate 20 and the cabinet body 10 is sealed by the sealing ring, so that a first heavy seal is formed. Then, the first magnetic component 81 is electrified and generates magnetic attraction under the action of the controller, the first magnetic component 81 and the second magnetic component 82 are magnetically attracted and fastened, and accordingly the sealing plate 20 and the cabinet 10 are connected and fastened, and further a second seal is formed. The upper electromagnet 41 is magnetically attracted and fastened to the upper magnetic stripe, and the lower electromagnet 42 is magnetically attracted and fastened to the lower magnetic stripe, thereby forming a third resealing. Thus, in the case of the triple seal described above, the cabinet 10 is tightly coupled with the sealing plate 20, and water is effectively prevented from entering the cabinet 10.
In addition, the transformer is placed on the pad column 60, so that on one hand, the transformer is not easy to be submerged by water, and on the other hand, even if water enters the cabinet body 10, the water can be discharged before the liquid level reaches the top surface of the pad column 60. The threshold range of the liquid level in the cabinet 10 is set, and the pipe orifice of the water inlet pipe 52 is lower than the top surface of the cushion column 60 as much as possible, so that the accumulated water in the cabinet 10 is effectively discharged.
When the water draining pipe 53 is installed, the lift of the water draining pipe may be 6-7m to drain accumulated water from underground to ground. And, the exit of the drain pipe 53 is designed with a protected and isolated area as much as possible to avoid water accumulation and drain the water as soon as possible.
Even under the condition of triple sealing, as long as the inner liquid level meter detects that the liquid level in the cabinet body 10 reaches the threshold range, the controller controls the drainage pump 51 to operate, so that water in the cabinet body 10 is drained, and a good drainage effect is achieved. Once the water level falls below the set threshold range, the controller controls the drain pump 51 to stop operating to prevent the pump from burning out. The minimum value of the threshold range of the water level in the cabinet 10 is necessarily smaller than the height of the top surface of the pad column 60, so that the water level is lower than the top surface of the pad column 60, and even if water enters the cabinet 10, the water level is not directly contacted with the transformer, and the transformer is not easily affected.
The sealing plate 20 is a metal plate, which can facilitate the diffusion of heat in the cabinet 10.
The water-immersion-proof transformer protective cabinet has good sealing effect, and can drain water even if the water is drained, so that the transformer is effectively prevented from being immersed by water.
The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.
