Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, and in particular to a high and low voltage prefabricated transformer substation. Background Art

[0002] Substations convert high voltage into low voltage to meet the electricity needs of urban residents and industrial users. Prefabricated substations integrate transformers, high and low voltage switchgear, etc. in one box. They have a compact structure, small footprint, are easy to install and move, and are easier to construct.

[0003] The commonly used high and low voltage prefabricated substations at present are generally composed of four parts: high-voltage switchgear, low-voltage distribution panel, distribution transformer, and casing. Since high and low voltage prefabricated substations are generally installed outdoors, collisions are inevitable, which can easily cause damage to the internal devices. In order to ensure the ventilation performance inside the high and low voltage prefabricated substations, vents are set on the surface of the high and low voltage prefabricated substations. Dust in the surrounding air enters the high and low voltage prefabricated substations. The dust particles will block the heat dissipation channels of the equipment, causing the equipment temperature to rise and affecting the normal operation of the equipment. Moreover, a high heat dissipation effect cannot be achieved only through the vents. Excessive temperature will accelerate the aging of the insulating material, reduce its insulation performance, and increase the risk of electrical failure. In addition, the equipment is directly fixed in the cabinet. During maintenance, workers need to enter the cabinet, which is inconvenient to operate.

[0004] Therefore, in order to solve the above-mentioned problems of poor anti-collision, poor heat dissipation performance and inconvenient maintenance, a high and low voltage prefabricated substation can be designed. Summary of the invention

Under the action of the shock-absorbing rod 44 and the first damping spring 45 The force is absorbed again, thereby reducing the impact force on the pre-installed cabinet 1. The water pool 5 has a waterproof effect. When it rains, rainwater enters the water pool 5 and is then discharged through the drain pipe 6, reducing rainwater splashing on the surface of the pre-installed cabinet 1. When the equipment is working, the cooling fan 8 is started, and the air is filtered by the first filter 7, blown to the body 11, and then blown out from the vent on the other side. Under the action of the wind, the dustproof plate 133 rotates upward, and the rotating shaft 132 rotates between the side plate 131 and the other side plate 131, which does not affect the discharge of hot air. When there is water accumulation around, the motor 34 in the U-shaped mounting frame 31 is started, and under the action of the driving gear 35 and the driven gear 36, the power is transmitted to the ball screw 32, and the screw pair 33 converts the rotary motion into a linear motion to raise the pre-installed cabinet 1, thereby preventing water from entering the pre-installed cabinet 1.

[0028] Through the above steps, the impact force is absorbed for the second time, which effectively reduces the impact force on the substation, allows the heat to dissipate quickly, effectively reduces the risk of electrical failure, and also extends the service life of the equipment. During maintenance and installation, the front and rear sliding adjustment makes maintenance and installation easier to solve the problems of anti-collision, poor heat dissipation performance and inconvenient maintenance.
