The presence of the borrowing plate 215 allows the mounting plate 214 to be retracted into the metrology chamber 210, providing room for the metrology device to be installed.

In other embodiments, the borrowing plate 215 may be hinged to the door frame of the metrology chamber 210.

The installation plate 214 and the borrowing plate 215 are arranged in the metering chamber 210 of the above embodiment, so that a proper installation space is provided for the metering device, and the space in the metering chamber 210 is reduced.

As shown in fig. 5 and 6, the box-type substation of the present embodiment further includes a wind shield. The windproof device comprises a placing frame 48 and a supporting rod 5. The placing frame 48 is fixedly welded on at least one of the cabinet doors of the high-pressure chamber 10, the low-pressure chamber 220 and the metering chamber 210, and a second positioning hole 49 is formed in a door frame hinged with the cabinet doors.

Illustratively, the first door 11 of the high-pressure chamber 10 is provided with a placing frame 48, and the door frame hinged to the first door 11 is provided with a second positioning hole 49. The rack 48 at least comprises a horizontal plate-shaped structure, and two first positioning holes 481 are arranged on the horizontal plate-shaped structure. The second positioning hole 49 may be provided on the lower edge of the door frame.

Both ends of the support rod 5 are bent towards the same side of the axis of the support rod 5, and the bending direction is along the radial direction of the axis of the support rod. When the cabinet door is opened, one end of the supporting rod 5 can be inserted into the first positioning hole 481, and the other end of the supporting rod 5 can be inserted into the second positioning hole 49. Even there is great wind, does not influence the staff and opens the cabinet door construction of box-type substation yet. When the wind-proof device is not needed (when the working time is short of a large wind, and thus the opened cabinet door is not needed to be fixed), the two ends of the supporting rod 5 may be inserted into the two first positioning holes 481 of the rack 48, respectively. The distance between the two first positioning holes 481 is determined according to the length of the middle portion (unbent section) of the support rod 5, and the length of the support rod 5 is determined according to the state of the cabinet door to be opened.

In other embodiments, the placing frame 48 may be disposed on the inner wall of the second door 211 of the measuring chamber 210, and the second positioning hole 49 may also be disposed on the door frame hinged to the second door 211, and/or the placing frame 48 may be disposed on the inner wall of the third door 221 of the low-pressure chamber 220, and the second positioning hole 49 may also be disposed on the door frame hinged to the third door 221.

In other embodiments, the placing rack 48 may be omitted, and the first positioning hole 481 may be directly disposed on the inner wall of the cabinet door, and the second positioning hole 49 may be disposed at the bottom of the door frame hinged to the cabinet door. When the wind-proof device is not required, the support rod 5 may be directly placed at a proper position in the high pressure chamber 10, the metering chamber 210 or the low pressure chamber 220.

The cabinet door of safety device guarantee each room can effectively be fixed after opening, and the cabinet door can not blown by wind and influence the construction to guarantee safety.

As shown in fig. 7-9, four hooks 45 are provided on the top of the outer sidewall of the box 41, and the hooks 45 are evenly distributed on the outer wall of the box 41 corresponding to the transformer chamber 30. In combination with the above embodiment, the box-type substation is convenient to move and reuse by using the lifting hook 45 because the box-type substation has a compact and small overall structure. In other embodiments, 6, 8, etc. hooks 45 may be provided.

Preferably, the high pressure chamber 10, the low pressure chamber 220 and the metering chamber 210 are arranged side by side in front of the transformer chamber 30, and the doors of the high pressure chamber 10 and the metering chamber 210 are arranged in front of the box 41. Due to the large volume of the transformer, the layout of the high voltage chamber 10, the low voltage chamber 220, the metering chamber 210 and the transformer chamber 30 is beneficial to reducing the volume of the whole box-type substation and to balancing the front and rear weights.

Preferably, the hooks 45 are provided on the side wall of the case 41 corresponding to the transformer room 30. Because the weight of the transformer is relatively large, the lifting hook 45 is arranged on the side wall of the box body 41 corresponding to the transformer chamber 30, so that the box-type substation can be better ensured to be more stable in the process of being lifted by the lifting equipment.

The side walls of the high-voltage chamber 10 and the low-voltage chamber 220 are both provided with heat dissipation windows 47, and insect-proof covers are arranged on the inner sides of the heat dissipation windows 47, so that insects are prevented from entering the indoor space to damage an electric device or cause a short circuit of a circuit of the electric device.

Preferably, the top cover plate 42 covers the case 41 integrally from above, and the top cover plate 42 is formed integrally, 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 recessed upwards, and the top of the box body 41 is positioned in the groove. This structural arrangement prevents rainwater from entering the interior of the tank 41.

The upper surface of the top cover plate 42 is gradually inclined downwards from the front to the back, so that water is not accumulated on the top of the top cover plate 42. In order to ensure that the upper surface of the top cover plate 42 is inclined downward from the front to the rear direction, the thickness of the top cover plate 42 may be set to be gradually reduced from the front to the rear direction, 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 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.

Referring to fig. 1, 7 and 9, a heat sink 44 is disposed at the rear portion of the transformer chamber 30, a protective cover 46 is disposed outside the heat sink 44, and ventilation holes are disposed on left and right sides, upper and lower sides and a rear side of the protective cover 46. The protective cover 46 may protect the heat sink 44 from impact.

As shown in fig. 3, the bottom of the high pressure chamber 10 is provided with a wire inlet hole 12 and three terminals 13. The wire inlet 12 is arranged at the bottom of the high-voltage chamber 10, and the three terminals 13 are arranged on the back plate of the high-voltage chamber 10, which is opposite to the cabinet door. The cables entering from the wire inlet hole 12 at the bottom of the high-voltage chamber 10 can be directly branched to the three binding posts 13, so that the operation is convenient, and the wiring connection condition can be conveniently checked. Preferably, a cable fixing device is arranged beside the wire inlet hole 12, and a cable entering from the wire inlet hole 12 is firstly fixed by the cable fixing device and then connected, so that the pulling force applied to the cable is further reduced, and the stable connection of the cable is ensured. Similarly, the bottom of the low pressure chamber 220 is provided with an outlet.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to fall within the scope of the present disclosure.
