Problems solved by technology
[0004] However, because it is generally installed in residential quarters, urban public substations, bustling downtown areas, etc., vehicle collisions may occur. Prefabricated substations are generally fixed directly on the base layer, which cannot well offset the impact force. Some prefabricated substations generally have vents directly on both sides of the box body, which cannot well block the entry of rainwater, which is not conducive to ensuring the safety of equipment operation

Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0035] refer to Figure 1-9 , a high-voltage and low-voltage prefabricated substation with good protection performance, including a bearing plate 12, the bearing plate 12 is made of metal material, has high strength, is convenient to connect with other components, and can ensure the firmness of the connection. The upper end of the bearing plate 12 A groove 26 is provided, and the bottom in the groove 26 is rotatably connected with a first gear 27. The first gear 27 can rotate in situ in the groove 26, and can ensure its stable rotation. The thickness of the first gear 27 is less than The depth of groove 26, one end sidewall in the groove 26 is provided with the first...

The invention discloses a high and low voltage prefabricated substation with good protection performance, which includes a bearing plate, a groove is arranged on the upper end of the bearing plate, a first gear is rotatably connected to the bottom of the groove, and the groove A first notch is provided on the side wall of one end inside, and a moving groove is arranged in the first notch, and a reset mechanism is arranged in the moving groove. The invention avoids the situation that the opening of the side wall of the box easily makes rain and snow enter the box in the past, and can also ensure a good heat dissipation capacity, ensure that the machine body can be in an adaptable working temperature environment, and at the same time make the baffle and the box The body is connected together to prevent the baffle from rotating at will, and can effectively cooperate with the box to isolate the body from the external environment. When a foreign object collides, the box and the baffle can prevent the body from being directly impacted, and through deflection and movement Ways to counteract external forces, to ensure that the body is not damaged, to ensure its normal operation, and to prolong its service life.
Description
technical field [0001] The invention relates to the technical field of prefabricated substations, in particular to a high and low voltage prefabricated substation with good protection performance. Background technique [0002] The prefabricated substation is electrically connected through cables or bus bars, and all high and low voltage power distribution devices and transformers are conventional stereotyped products. The prefabricated substation has the advantages of small size, small footprint, light weight, low cost, and reliability. It is also called "box-type substation" or "prefabricated substation. [0003] Prefabricated substations can generally be controlled and managed remotely, which can ensure safe and reliable operation, and have the advantages of convenient maintenance, small amount of on-site installation, short installation and commissioning cycle, and movement with the load center, making them suitable for: "residential districts, Urban public substation, b...
