Abstract
The utility model discloses a power distribution cabinet capable of automatically reducing the temperature, comprising a power distribution cabinet body and an electrical element positioned in the power distribution cabinet body. A temperature sensor is arranged in the power distribution cabinet body and connected with a temperature controlled switch which is connected with a semiconductor refrigerator through a power source. In the utility model, the temperature sensor and the temperature controlled switch are arranged in the power distribution cabinet body, therefore, when the temperature sensed by the temperature sensor reaches the set threshold, the power source is connected by the temperature controlled switch and supplies power for the semiconductor refrigerator, and the semiconductor refrigerator starts working. Since the semiconductor refrigerator is attached to the electrical element easy to heat, instant temperature reduction can be realized when a semiconductor works and the efficiency is high. The utility model does not destroy a shell of the traditional device, ensures the cleanness of operation environment of internal equipment and has simple structure, no vibration, long service life, simple installation and maintenance as well as no noise, no wear, high cooling speed, convenience for temperature control and the like.
Description
Technical field
The utility model relates to a kind of power distribution cabinet, specifically relates to a kind of power distribution cabinet that can lower the temperature automatically when the power distribution cabinet temperature is too high.
Background technology
Existing power distribution cabinet cooling generally adopts mechanical fans aeration-cooling, perhaps has the purpose that louvre reaches cooling on the cabinet of power distribution cabinet.It is low that these technology all exist radiating efficiency, needs to leave ventilating opening simultaneously, causes dust to enter easily, reduces the functional reliability of equipment in the power distribution cabinet; In addition, the heat radiation of fan forced ventilation is because long-time running is prone to failure problems.Because so above-mentioned problem in use, is often just reported to the police to temperature is too high, the staff obtains overhauling after the alarm signal again, and efficient is not high.
The patent No. is 200820098293.1, name is called " the semiconductor heat sink of airtight small-sized cabinet ", though proposed a kind of cooling measure, but owing to adopt water-cooled cooling in use, safe operation to power equipment impacts easily, so be not suitable for extensive use in power equipment.
Summary of the invention
The purpose of this utility model provides a kind of power distribution cabinet that can lower the temperature automatically when the distribution in-cabinet temperature is too high.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises the distribution cabinet and is positioned at the electric component of distribution cabinet, and be provided with temperature sensor in the distribution cabinet, temperature sensor is connected with temperature detect switch (TDS), and temperature detect switch (TDS) is connected with semiconductor cooler by power supply.
For carrying out remote monitoring, above-mentioned temperature sensor is connected with temperature detect switch (TDS) by controller.
Say that further above-mentioned controller is positioned at the Long-distance Control machine room, controller and temperature sensor, temperature detect switch (TDS) wireless connections.
Above-mentioned temperature detect switch (TDS) is resistance-type thermostat or thermojunction type thermostat.
In addition, can also be provided with fin on the surface of semiconductor cooler.
The inside and outside fan that is equipped with of above-mentioned distribution cabinet.
Adopt the utility model of technique scheme, temperature sensor and temperature detect switch (TDS) are installed, like this in power distribution cabinet, when the detected temperature of temperature sensor reaches preset threshold, temperature detect switch (TDS) is with power connection, and power supply is powered to semiconductor cooler, semiconductor cooler work.Because semiconductor cooler is attached on the electric component of easy heating, so but when semiconductor is worked instantaneous temperature reduction, the efficient height.The utility model does not destroy the shell of original device, guarantees the cleaning of its internal unit running environment, and simple in structure, friction, and the life-span is long, and installation and maintenance are simple, have noiselessness, do not have wearing and tearing, cooling rate is fast, is convenient to advantages such as temperature control.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises distribution cabinet 7 and is positioned at the electric component 1 of distribution cabinet 7, be provided with temperature sensor 2 in distribution cabinet 7, temperature sensor 2 is connected with temperature detect switch (TDS) 3, and temperature detect switch (TDS) 3 is connected with semiconductor cooler 5 by power supply 4.In implementation process, temperature sensor 2 detects the temperature of electric component 1 in the distribution cabinet 7 in real time, when temperature is higher than the threshold value that sets, and temperature detect switch (TDS) 3 actions, energized 4.The positive pole of power supply 4 is connected the N type semiconductor contact metal film input stage of semiconductor cooler 5, and the negative pole of power supply 4 is connected the P type semiconductor contact metal film input stage of semiconductor cooler 5, and like this, semiconductor cooler 5 is started working, rapidly refrigeration.When temperature is lower than the threshold value that sets, temperature detect switch (TDS) 3 actions, power supply 4 disconnects, and semiconductor cooler 5 quits work.
It is pointed out that in the utility model power supply 4 can come from the power distribution cabinet, with handled easily; When the power supply in the power distribution cabinet is alternating current, need the AC-DC conversion module, above-mentioned AC-DC conversion module technology well known to those of ordinary skill in the art.In addition, for reaching better refrigeration, semiconductor cooler 5 is arranged on the wall of distribution cabinet 7, and it is positioned at semiconductor cooler 5 refrigeration of distribution cabinet 7 inside, and it is positioned at semiconductor cooler 5 heatings of distribution cabinet 7 outsides.In the utility model, on the surface of semiconductor cooler 5, be provided with fin 8, be used for the cold air and the hot gas on semiconductor cooler 5 surfaces are scattered rapidly.For reaching better effect, can also be at the inside and outside fan that all is provided with of distribution cabinet 7.
Above-mentioned temperature detect switch (TDS) 3 is resistance-type thermostat or thermojunction type thermostat, and they are technology well known to those of ordinary skill in the art.
For realizing remote monitoring, above-mentioned temperature sensor 2 is sent to the temperature value that collects in the controller 6 by wireless network earlier.Controller 6 is positioned at the Long-distance Control machine room, after it receives the temperature value that sends, handle by analysis, and in back-end data base record this time information, pass through the wireless network transmitting control commands then to temperature detect switch (TDS) 3, temperature detect switch (TDS) 3 is received energized 4 after the order, makes semiconductor cooler 5 refrigeration of starting working.Above-mentioned wireless network can be any one among Zigbee, Wi-Fi, RF, Bluetooth, UWB, NFC, GPRS, the 3G.
