Description

A kind of autocontrol temperature power distribution cabinet

Technical field

The utility model relates to electrical equipment technical fields, and in particular to a kind of autocontrol temperature power distribution cabinet.

Background technique

Power distribution cabinet is that electric appliance and its route are placed on chest therein, for distributing electric power energy, is referred to as electric distribution Center.They install the substation in enterprise concentratedly, electric energy are distributed to junior's controller switching equipment of different location.In order to which waterproof is anti- Dirt power distribution cabinet is typically all Seal Design, and power distribution cabinet internal component (especially high-power power distribution cabinet) is under energization service condition Itself can generate biggish heat, be easy to that accident occurs in unattended situation, cause personnel's property loss, but at present Power distribution cabinet heat dissipation effect it is general, those skilled in the art wishes can to do more preferable.

Utility model content

The utility model in view of the above shortcomings of the prior art, has invented a kind of autocontrol temperature power distribution cabinet.

To achieve the goals above, the utility model adopts the following technical solutions:

A kind of autocontrol temperature power distribution cabinet, including power distribution cabinet, siphunculus, bell mouth, cool room, semiconductor chilling plate and floating ball, The lower end of the siphunculus is connected to power distribution cabinet, and the upper end of siphunculus is connected to cool room；Bell mouth is provided in the siphunculus, it is described Floating ball be placed on bell mouth；Semiconductor chilling plate, the semiconductor are provided on the top surface of the cool room The cold end face of cooling piece is in cool room, and the hot end face of semiconductor chilling plate is exposed to outside cool room.

The innovative point of the utility model is the hot-air for carrying out refrigeration using semiconductor chilling plate with generating in power distribution cabinet It is neutralized, it is final to realize that distribution in-cabinet temperature is able to maintain that in allowed limits；Using floating between cool room and power distribution cabinet Ball sealing mouth, the temperature elevated pressure only in power distribution cabinet, which reaches certain value Shi Caineng, floats floating ball, cool room and distribution box this The air of two spaces could neutralize.

It further, further include temperature sensor and controller, the temperature sensor is arranged in cool room, described Controller is mounted on outside cool room；The temperature sensor and semiconductor chilling plate is electrically connected with controller respectively；Partly lead Body cooling piece, which once freezes, repeatedly to be neutralized, when can not neutralization temperature increase temperature sensor setting parameter when control Device can just control semiconductor chilling plate refrigeration, so relatively power saving.

Further, further include air releasing device, be provided with air releasing device on the top of the cool room, avoid the pressure of cool room It is strong it is excessive cause it is in hot and cold air and difficult.

Further, the discouraged value of the air releasing device is 3 atmospheric pressure.

Further, the weight of the floating ball is 200~300 grams, and the sealing to bell mouth gently cannot be achieved very much in floating ball；It is floating Ball is too heavy, and the pressure needs in power distribution cabinet are very big just to make floating ball float, and the temperature in the bigger power distribution cabinet of pressure will be higher.

Utility model has the advantages that

1. the utility model freezes to air using semiconductor chilling plate, the hot-air in cold air and power distribution cabinet into Row neutralizes, and realizes the control to distribution in-cabinet temperature；

2. semiconductor chilling plate is not needed long-term work, is increased the use of semiconductor using the mode of interruption sex work Service life, while power consumption is also few；

3. its structure simple designs is reasonable, automation control can be realized, simple and easy to use, great market potential.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of autocontrol temperature power distribution cabinet of the utility model.

Specific embodiment

The utility model is described in detail below in conjunction with attached drawing:

In the description of the present invention, it should be noted that the orientation or positional relationship of the instructions such as " lower end ", " upper end " For be based on the orientation or positional relationship shown in the drawings or the utility model product using when the orientation or position usually put Relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning must There must be specific orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

As shown in Figure 1, a kind of autocontrol temperature power distribution cabinet, including power distribution cabinet 1, siphunculus 2, bell mouth 3, cool room 4, semiconductor The lower end of cooling piece 5, floating ball 6, temperature sensor 7 and controller 8, the siphunculus 2 is connected to power distribution cabinet 1, and connectivity part is arranged to Horn mouth；The upper end of siphunculus 2 is connected to cool room 4.Bell mouth 3 is provided in the siphunculus 2, bell mouth 3 is upper and lower bell mouth Shape, floating ball 6 is placed on bell mouth 3, is specifically located on upper hopper mouth.The weight of floating ball 6 can be according to power distribution cabinet 1 Power and select, the range being typically chosen be 200~300 grams.Semiconductor refrigerating is provided on the top surface of the cool room 4 The cold end face of piece 5, semiconductor chilling plate 5 is in cool room 4, and the hot end face of semiconductor chilling plate 5 is exposed to outside cool room 4, The cold end face of semiconductor chilling plate 5 is to freeze to the air in cool room 4, and hot end face is exposed to outside cool room 4, main If cooling fin can also be arranged on the face of hot end in order to which hot end face can quickly be radiated, accelerate radiating efficiency.

In order to realize that temp autocontrolled in power distribution cabinet 1, described temperature sensor 7 is arranged in cool room 4, the control Device 8 processed is mounted on outside cool room 4；The temperature sensor 7 and semiconductor chilling plate 5 is electrically connected with controller 8 respectively.? Need to be arranged in controller 8 two temperature, a maximum temperature, a minimum temperature, when temperature sensor 7 detects before use Controller 8 controls semiconductor chilling plate 5 and works when to maximum temperature；The controller 8 when temperature sensor 7 detects minimum temperature Control semiconductor chilling plate 5 stops working, and the interruption sex work of semiconductor chilling plate 5 has been achieved, has extended semiconductor system Cold 5 service life, reduces power consumption.

In order to avoid cool room 4 in hot and cold air and during indoor pressure it is excessive and influence in sum effect, The air releasing device 9 that value is 3 atmospheric pressure of losing heart is provided on the top of cool room 4, i.e., when the air pressure in cool room 4 is greater than or waits Air releasing device 9 could lose heart when 3 atmospheric pressure, and principle is as the gas bleeder valve of pressure cooker.

Although the specific embodiment of the utility model is described in detail and is illustrated above, it should be noted that Be that we can make various changes and modifications the embodiment above, but these without departure from the utility model spirit and Range documented by the attached claims.
