Description
Technical field
The present invention relates to power cabinet technical field, be specifically related to a kind of SCM Based intelligent constant-temperature high frequency electric source switch cubicle.
Background technology
At present, high-frequency switch rectifying power supply has been widely used in the fields such as telecommunications, electric power, oil, once electric main breaks down, high-frequency switch rectifying power supply will lean on its standby battery group to maintain the power supply to DC load, the discharge time of batteries is limited, not president's time sustain discharge.
In the multiple occasions such as power plant, transformer station, UPS system, batteries is the visual plant that ensures uninterrupted power supply and Emergency use, and when batteries is normally worked, its working temperature is to weigh the important parameter whether batteries normally works.Many conventional electronic and electrical equipments and components and parts very difficult long term maintenance under high ambient temperature is normally moved, at high temperature operation, and equipment itself needs to produce more heats, cause the interior temperature rise of rack very high, thereby acceleration equipment is aging and inefficacy.Therefore, normally work, extend their useful life for meeting device interior and components and parts, the ambient temperature in rack need to be remained in the temperature range that equipment and components and parts can normally work; In addition, dust is also the reason that power source loads increases, reduces its useful life.
Temperature Difference Ratio is larger throughout the year, and easily aging electric equipment switch, disconnecting link and the ebonite fittings of causing in terminal box be as the dielectric strength of connecting terminal block reduces and produces and puncture, and causes that switch closes by mistake, false tripping and cause power outage.Bring very large hidden danger to safety in production, adaptive capacity to environment is poor.
Summary of the invention
For above-mentioned prior art, the object of the present invention is to provide a kind of SCM Based intelligent constant-temperature high frequency electric source switch cubicle, be intended to solve the problem that causes device aging because variations in temperature is excessive.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of SCM Based intelligent constant-temperature high frequency electric source switch cubicle, it is characterized in that, comprise high frequency switch power cabinet cabinet, and be arranged on the thermostatic control system in high frequency switch power cabinet cabinet, described thermostatic control system comprises temperature monitor, the first relay, the second relay, transistor cooling piece, fin, cooling fan, heating resistor and single-chip microcomputer, described temperature monitor is connected to described single-chip microcomputer, the control end of the first relay and the second relay is connected to single-chip microcomputer through a triode respectively, transistor cooling piece is connected with fin, fin both sides connect respectively two cooling fans, the normally opened contact of described the first relay and transistor cooling piece, the power end series connection of cooling fan, the second relay is connected with the power end of heating resistor.
The present invention also comprises a RS-485 communication interface, and described RS-485 communication interface is connected with single-chip microcomputer.
Compared with prior art, the present invention has following beneficial effect:
The present invention has ensured that the temperature in power cabinet, all the time in temperature constant state, is difficult for electric elements aging, prevents that the situation of unpredictable factor from occurring, thereby ensures the safe operation of electric power system.
Brief description of the drawings
Fig. 1 is thermostatic control system schematic diagram provided by the invention.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
A kind of Long-distance Control dehumidification type high frequency switch power cabinet, comprises high frequency switch power cabinet cabinet, relative humidity sensor, triode, relay, single-chip microcomputer, semiconductor chilling plate and RS-485 communication interface; High frequency switch power cabinet cabinet entirety is hermetically-sealed construction, on the left plate of high frequency switch power cabinet cabinet, is provided with drying box, is at least placed with one bag of drier in drying box; The P0 port of described single-chip microcomputer connects the signal output part of relative humidity sensor, P1 port connects RS-485 communication interface, P3 port is connected with the base stage of described triode, the emitter of triode connects the most control coil of relay, and the normally opened contact of described relay is connected with the DC power supply of powering for described semiconductor chilling plate.Described drier is anhydrous cupric sulfate or calcium chloride.The present invention can Long-distance Control semiconductor chilling plate, hour only just can dehumidify by drier in relative humidity, when relative humidity is larger, the unlatching that remote center can Long-distance Control semiconductor chilling plate or close, save like this energy consumption, extended the useful life of semiconductor chilling plate.
