Preferably, the bottom of described transformer room is provided with and is communicated with outside drainage pipe, and described drainage pipe is provided with silica gel valve.
Preferably, be provided with antiseepage bakie in described upper box, described antiseepage bakie is by antiseep flexible pipe and ft connection.
Preferably, described ventilation window is connected with the second respirator.
The utility model is intended to, will need in box-type substation ventilate and the hyperbaric chamber of waterproof and transformer room be isolated, high tension apparatus in hyperbaric chamber, the air heats in hyperbaric chamber is made after producing heat, the air be heated enters transformer room by the conduction pipe at top, hyperbaric chamber, and gas is discharged by the ventilation window in transformer room; Enter in the process of transformer room at the air be heated, hyperbaric chamber enters the air pressure in air balance hyperbaric chamber by respiratory siphon.

Describe these and other aspect of the present utility model in further detail now with reference to appended accompanying drawing, it is depicted as currently preferred embodiment of the present utility model.Wherein:
Fig. 1 is the structure chart of the present embodiment;
Fig. 2 is the cut-away view of Fig. 1.
In figure: 11, upper box cavity; 111, conduction pipe; 112, glazed tiles; 113, antiseepage bakie; 1131, antiseep flexible pipe; 121, hyperbaric chamber; 122, transformer room; 1221, ventilation window; 123, low-pressure chamber; 21, respiratory siphon; 22, drainage pipe; 221, silica gel valve; 31, the first respirator; 32, the second respirator.
Embodiment
Below in conjunction with accompanying drawing and instantiation, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of waterproof box-type substation, comprises casing, and the inside of casing is longitudinally separated into upper box cavity 11 and lower box cavity by the first dividing plate.
So, when having water accumulation leaking at casing top, only can enter upper box inner chamber, and damage can not be caused to the electric elements in lower box cavity.
Further, lower box cavity is laterally separated into hyperbaric chamber 121, transformer room 122 and low-pressure chamber 123 by second partition, as shown in Figure 2, conduction pipe 111 is provided with in upper box cavity 11, one end of conduction pipe 111 is communicated with at the top in hyperbaric chamber 121, and the other end is communicated with at the top of transformer room 122, and the bottom in hyperbaric chamber 121 is provided with respiratory siphon 21, respiratory siphon 21 is communicated with the first respirator 31 being placed in casing outside, and transformer room 122 is provided with ventilation window 1221.
So, the present embodiment will need ventilate and the hyperbaric chamber 121 of waterproof separated by second partition with transformer room 122; So, the high tension apparatus in hyperbaric chamber 121 can make the air heats in hyperbaric chamber 121 after producing heat, and the air be heated enters transformer room 122 by the conduction pipe 111 at top, hyperbaric chamber 121, and gas is discharged by the ventilation window 1221 in transformer room 122; Enter in the process of transformer room 122 at the air be heated, hyperbaric chamber 121 enters the air pressure in air balance hyperbaric chamber 121 by respiratory siphon 21, and the moisture in air can be discharged by the first respirator 31 simultaneously, prevents the etch of high tension apparatus.
By above-mentioned design, because transformer room 122 is provided with the ventilation window 1221 for ventilating, so, ponding, snow etc. easily enters to transformer room 122 from ventilation window 1221, causes transformer room 122 internal water accumulation.So, be provided with in the bottom of transformer room 122 and be communicated with outside drainage pipe 22, drainage pipe 22 is provided with silica gel valve 221, so, when transformer room's 122 internal water accumulation, ponding can be expelled to outside from drainage pipe 22, and silica gel valve 221 can prevent ponding or extraneous air, when there is no ponding in transformer room 122, enter transformer room 122 from drainage pipe 22.
Preferably, for landscape type box-type substation, it is in order to integrally-built attractive in appearance, can install glazed tiles 112 at the top of casing, and glazed tiles 112 very easily seepage ponding; So, be provided with antiseepage bakie 113 in casing, antiseepage bakie 113 is by antiseep flexible pipe 1131 and ft connection; Can collect like this by the ponding of glazed tiles 112 gap seepage and discharge, preventing ponding from putting aside for a long time in upper wall cavity, cause body of wall to damage.
Preferably, ventilation window 1221 is connected with the second respirator 32; So, the moisture in extraneous air can not enter transformer room 122 by ventilation window 1221, prevents the ponding that may enter in the present embodiment hyperbaric chamber 121 further.
Further, hyperbaric chamber 121, transformer room 122 and low-pressure chamber 123 are equipped with the independent chamber door opened and closed, and ventilation window 1221 and the second respirator 32 are all fixed on the chamber door of transformer room 122, are convenient to the maintenance of the second respirator 32.
