In addition, if there is a description of "first", "second", etc. in an embodiment of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
As shown in fig. 1 to 4, a box-type substation includes a box body 41 and a ceiling plate 42. The box 41 is surrounded by four side wall plates perpendicular to the horizontal plane in the front, rear, left and right directions and a bottom plate parallel to the horizontal plane, that is, the box 41 is hollow and has an open upper end. The top cover plate 42 covers the top opening of the box 41 and is fixedly connected with the top of the box 41. The high-voltage chamber 10, the low-voltage chamber 20 and the transformer chamber 30 are isolated from each other in the case 41. The partition mode can be that a partition plate is welded or fixedly installed by screws between two adjacent chambers, and in other embodiments, several cuboids which are hollow and have openings inside can be welded back to back or fixedly connected together by screws. A high-voltage wire inlet device, an insulating device, a lightning arrester and the like are arranged in the high-voltage chamber 10, a transformer, accessories thereof and the like are arranged in the transformer chamber 30, and a metering device, a low-voltage wire outlet device and the like are arranged in the low-voltage chamber 20.
Wherein the high voltage chamber 10 and the low voltage chamber 20 are arranged side by side in front of the transformer chamber 30. A metering chamber 210 and a line outlet chamber 220 which are mutually separated are arranged in the low-pressure chamber 20, and the metering chamber 210 is arranged between the high-pressure chamber 10 and the line outlet chamber 220. The separation of the metering chamber 210 and the outlet chamber 220 can be the same as the above separation, and will not be described herein. The metering device is disposed within the metering chamber 210 and the low voltage line outlet device is disposed within the outlet chamber 220.
The high pressure chamber 10, the metering chamber 210 and the outlet chamber 220 are provided with separate cabinet doors. For convenience of description, we define: the cabinet door of the high-voltage chamber 10 is a first cabinet door 11, the cabinet door of the metering chamber 210 is a second cabinet door 211, and the cabinet door of the outlet chamber 220 is a third cabinet door 221. The cabinet door of the high pressure chamber 10 (i.e., the first cabinet door 11) and the cabinet door of the metering chamber 210 (i.e., the second cabinet door 211) are disposed at the front side of the case body 41, and the cabinet door of the outlet chamber 220 (i.e., the third cabinet door 221) is disposed at the right side of the case body 41. This effectively reduces the required width of the low pressure chamber 20 in the left-right direction, and makes the occupied space of the low pressure chamber 20 smaller. The high pressure chamber 10, the metering chamber 210 and the low pressure chamber 220 are respectively provided with door frames, the first cabinet door 11 is hinged with the door frame of the high pressure chamber 10, the second cabinet door 211 is hinged with the door frame of the metering chamber 210, and the third cabinet door 221 is hinged with the door frame of the low pressure chamber 220.
A protection cabinet door 212 is further arranged in the second cabinet door 211 of the metering chamber 210, and when the second cabinet door 211 and the protection cabinet door 212 are both closed, the protection cabinet door 212 is parallel to the second cabinet door 211. An observation window 213 is arranged on the protection cabinet door 212, and transparent organic glass can be arranged on the observation window 213. Since the metering devices and the like need to be provided in the metering chamber 210 for inspection or verification by the power supply office or the power supply office, and these metering devices need a higher level of protection. Therefore, the protection cabinet door 212 and the observation window 213 are arranged, the metering instrument can be observed through the observation window 213, the protection cabinet door 212 can protect the metering device in the metering chamber 210 from safe operation, meanwhile, the mistaken collision of personnel is reduced, and the potential safety hazard is reduced.
It should be noted that, for a box-type substation provided with a high-voltage metering chamber, a protection cabinet door 212 similar to the above embodiment may also be provided in the high-voltage metering chamber, and details are not described here.
In the embodiment, the metering chamber 210 and the wire outlet chamber 220 of the low-pressure chamber 20 are respectively and independently arranged, and the cabinet doors of the metering chamber 210 and the wire outlet chamber 220 are respectively arranged on different side walls of the box body 41, so that the structure is more reasonable, and the whole volume and the floor area of the box-type substation can be effectively reduced; meanwhile, the safety of different personnel in checking and maintaining the box-type transformer substation can be guaranteed. For example, in general, the metering device can be managed by the power supply bureau through the metering chamber 210, and the user generally only needs to perform corresponding operations in the outlet chamber 220.
As shown in fig. 5 and 6, the top cover plate 42 covers the case 41 entirely from above, and the top cover plate 42 is integrally formed, and preferably has a horizontal shape so as to cover the entire top of the case 41. The bottom of the top cover plate 42 is provided with a groove 421 recessed upwards, and the top of the box body 41 is positioned in the groove 421. This structural arrangement prevents rainwater from entering the interior of the tank 41.
The height of the top cover plate 42 is gradually reduced along the direction from the front to the back, and water is not accumulated on the top of the top cover plate 42. In order to ensure that the height of the top cover plate 42 is gradually reduced from the front to the back, the top cover plate 42 may be gradually reduced from the front to the back, and of course, the thickness of the top cover plate 42 may be uniformly set, so that the height of the top of the sidewall of the box body 41 is gradually changed.
The box body 41 and the whole top cover plate 42 of the above embodiment form the shell of the whole box-type substation, so that the structure of the whole substation is more compact; the top cover plate 42 is buckled on the top of the box body 41 like a hat, and the top cover plate 42 inclines from the front to the rear side, so that the wind and rain resistance of the transformer substation can be enhanced, and the top of the top cover plate 42 is facilitated to drain water.
As shown in fig. 4 to 6, the rear end of the top cover plate 42 extends to a certain area behind the transformer chamber 30. Since the heat sink 44 is disposed at the rear portion of the transformer chamber 30, the protective cover 46 is disposed outside the heat sink 44, and the air holes are formed at the left and right sides, the upper and lower sides, and the rear side of the protective cover 46, the protective cover 46 can protect the heat sink 44 from being collided. Therefore, the rear end of the top cover plate 42 extends to a certain area towards the rear of the transformer chamber 30, which not only can ensure the front-back balance of the weight of the top cover plate 42 on the top of the box body 41, but also can play a role in protecting the heat sink 44 to a certain extent.
Referring to fig. 6 and 9, a fixing bracket 43 is disposed on the outer wall of the casing 41 corresponding to the rear side of the transformer chamber 30 and near the top thereof. The fixing bracket 43 includes a triangle 431 and a support plate 432. The triangular plate 431 is of a right-angled triangular plate-shaped structure, wherein one right-angled edge of the triangular plate 431 is fixedly connected with the outer wall of the box body 41, and the right-angled edge is vertical to the horizontal plane; the other right-angled edge of the triangle 431 is fixedly connected to the support plate 432, and the right-angled edge is parallel to the horizontal plane.
The support plate 432 includes a first connection plate and a second connection plate, which are perpendicular to each other and fixedly connected to each other. Wherein, the first connecting plate is parallel to the horizontal plane, the lower surface of the first connecting plate is fixedly connected with one right-angle edge of the triangular plate 431, and the end part of the first connecting plate is fixedly connected with the outer wall of the box body 41. The second connecting plate is a vertical plate, a bending edge which is bent by 90 degrees towards the inner direction of the box body 41 is arranged at the top of the second connecting plate, and the edge of the top cover plate 42 is dragged by the upper surface of the bending edge and is fixedly connected with the top cover plate 42 through screws.
