Specific embodiment

The utility model is described in further detail below with reference to embodiment, but the embodiments of the present invention is not It is limited to this.

Embodiment 1:

As shown in Fig. 2, the utility model is in order to overcome the drawbacks of the prior art, wind is additionally arranged in air inlet area and wind outlet area Machine.

A kind of box-type substation, mainly by cabinet 1, top cover 2, high-tension switch cabinet 3, transformer 4, low-tension switch cabinet 5 and anti- Water-bed seat 6 is constituted, and catching sheet 11 is equipped with inside the cabinet 1, and cabinet 1 is successively divided into out by the catching sheet 11 from top to bottom Wind area 12, power zone 13 and air inlet area 14；Be equipped with axial flow blower 121 inside the wind outlet area 12, the axial flow blower 121 with go out Wind area side wall 11 is fixedly connected by way of bolt and 121 opposing sidewalls of axial flow blower are equipped with exhaust vent 122；The air inlet No less than one centrifugal fan 144 is equipped with inside area 14, which is distributed in the first isolation ward 131, second Isolation ward 132,133 lower part of third isolation ward and centrifugal fan 144 are fixedly connected in a manner of bolt with 1 inner bottom surface of cabinet； Since the centrifugal fan 144 in air inlet area 14 generates upward wind, wind passes through power zone 13 from air inducing hole 111 and takes away The heat that 13 internal high pressure switchgear 3 of power zone, transformer 4, low-tension switch cabinet 5 generate when operating, then again passes through air inducing Hole 111, reaches wind outlet area 12, and the axial flow blower 121 of wind outlet area 12 is fixedly connected with the catching sheet of 12 bottom of wind outlet area, thus goes out Wind area 12 can generate one toward the wind blown in 121 opposing sidewalls of axial flow blower, and the wind of wind outlet area 12 mixes with power zone 13 The wind of heat is finally blown out via the exhaust vent 122 on side wall toward blowing on side wall；By the centrifugal fan 144 for entering the wind area 14 It cooperates with the axis stream 121 of wind outlet area 12, so that the heat inside power zone 13 is quickly taken out of, avoids because temperature is excessively high And damage the high-tension switch cabinet 3 inside power zone 13, transformer 4 and low-tension switch cabinet 5.Furthermore on air inlet 14 inner sidewall of area also Equipped with HEPA high efficiency particulate air 141,141 pairs of the HEPA high efficiency particulate air air entered inside cabinet 1 are filtered, and reduce case The content of dust and impurity in 1 inner air of body effectively protects the associate power equipment inside cabinet 1.

Embodiment 2:

The present embodiment on the basis of embodiment 1, discloses a kind of preferred structure of temperature control, as shown in figure 3,

First isolation ward 131, the second isolation ward 132,133 side wall of third isolation ward are equipped with temperature inductor 134, The temperature inductor 134 is threadably secured connection with isolation ward side wall and temperature inductor 134 is electrically connected with master controller 142 It connects, the master controller 142 is electrically connected with centrifugal fan 144, axial flow blower 121.In use, first to master controller 142 Pre-set programs set the temperature value of a unlatching centrifugal fan 144 and axial flow blower 121, are then felt by temperature inductor 134 Know the temperature inside each isolation ward, when the temperature value of indoor temperature arrival setting is isolated, temperature inductor 134 passes signal Master controller 142 is given, master controller 142 parses signal, and parsing finishes, and is confirmed whether to meet and opens centrifugal fan 144 and axial flow blower 121 requirement, if it is satisfied, master controller 142 just to corresponding blower send open command, it is centrifugal Blower 144 and axial flow blower 121 are opened after receiving order, if finding after the signal of 142 resolution temperature inductor 134 of master controller It is unsatisfactory for the condition opened, then master controller 142 does not send order to centrifugal fan 144, axial flow blower 121；In temperature value In the case that not up to preset value, centrifugal fan 144 and axial flow blower 121 are not turned on, due to being provided with ventilation on isolation ward Hole 7 can carry out Temperature fall by 7 isolation ward of ventilation hole, effectively save the energy, achieving environmental protection and energy saving.

The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model System, any simple modification made by the above technical examples according to the technical essence of the present invention, equivalent variations, each falls within Within the protection scope of the utility model.
