Description

Technical Field

[0001] The utility model relates to the field of transformer substations, in particular to a prefabricated transformer substation. Background Art

[0002] Substation is a place where voltage is changed. In order to transmit the electric energy generated by the power plant to a distant place, the voltage must be increased and converted into high voltage electricity. When it reaches the vicinity of the user, the voltage must be lowered as needed. This work of raising and lowering the voltage is completed by the substation. The main equipment of the substation is switches and transformers. Substations include "step-up and step-down" substations of various voltage levels. Prefabricated substations realize electrical connection through cables or busbars. All high and low voltage distribution devices and transformers are conventional standard products. Prefabricated substations have the characteristics of small size, small footprint, and light weight. They are widely used in residential areas and urban residential areas.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0021] See also Figure 1-4 As shown, an embodiment of the present application provides a technical solution: a prefabricated substation, including a box body 110, support seats 120 are arranged on both sides of the lower part of the box body 110, and a plurality of support grooves 121 are arranged on the support seat 120. A support plate 130 is also arranged at the lower part of the box body 110, and movable plates 140 are arranged on both sides of the support plate 130. A guide mechanism 200 is arranged below the support plate 130, and the support plate 130 can move up and down along the guide mechanism 200, and then open the movable plate 140 outward and extend to the support groove 121, so as to support the support plate 130 to a certain height.

[0022] The support plate 130 is mainly used to facilitate maintenance personnel to stand. A bakelite board is also provided above the support plate 130 . It is not easy for maintenance personnel to form a conductive path when standing on the bakelite board.

[0023] The operating principle of the device is: when the maintenance personnel need to stand at a higher position to repair the equipment on the transformer station, lift the support plate 130, and then move the movable plate 140 to both sides until the movable plate 140 is stuck in the support groove 121, so that the support plate 130 is fixed to a certain height, and the maintenance personnel can stand on it. If the standing position is not high enough, the support plate can be further lifted to a higher height to fix it.

[0024] Preferably, a first groove 131 is provided on one of the support plate 130 or the movable plate 140 , and a first protrusion 132 is provided on the other of the support plate 130 or the movable plate 140 , and the first protrusion 132 slides in the first groove 131 .

[0025] Preferably, the guide mechanism 200 includes a first hinge support 210 arranged at the bottom of the box body 110 and a second hinge support 220 arranged at the bottom of the support plate 130, one end of the first shearing plate 230 is rotatably connected to the first hinge support 210, one end of the second shearing plate 240 is rotatably connected to the second hinge support 220, and the other end of the first shearing plate 230 and the other end of the second shearing plate 240 are also rotatably connected.

[0026] Because a connecting shaft is installed between the hinge support and the scissor plate, the guide mechanism cannot rotate and can only move upward, thus playing a preliminary guiding role.

[0027] Preferably, a support rod 150 is disposed below the support plate 130 , and a rubber pad 160 is further disposed on the lower surface of the support rod 150 .

[0028] Preferably, a fastening hole 141 is further provided above the movable plate 140 .

[0029] Preferably, the height of the support groove 121 is greater than the height of the movable plate 140 , a second groove 122 is further provided in the support groove 121 , and a second protrusion 142 is provided at a corresponding position of the movable plate 140 , and the second protrusion 142 can be inserted into the second groove 122 .

[0030] Preferably, a first slanted roof 170 is provided above the box body 110, and an opening 171 is provided in the middle of the first slanted roof 170, and an exhaust fan is provided in the opening.

[0031] Preferably, a second sloping roof 180 is provided above the opening 171.
