Technical field
The present invention relates to electric power online monitoring technical field.
Background technology
On-line monitoring device for transmission line is capable of the running situation of effective monitoring transmission line of electricity, but at low ambient temperatures,
Influenceed by low temperature, cause on-Line Monitor Device reliability not high, therefore, low temperature environment is to hinder on-Line Monitor Device development
A significant obstacle, the mode of generally use increase thermal source influences on-Line Monitor Device, still, because thermal source belongs to electricity consumption
Larger load is measured, also, on-Line Monitor Device is generally adopted by solar power generation, wind-power electricity generation etc. on the tower of transmission line of electricity
Mode, the needs of thermal source heating power can not be met afterwards.Due to on-Line Monitor Device at low temperatures lie substantially in
The same cryogenic conditions of environment temperature, and being influenceed serious element by low temperature environment mainly has battery and electrochemical capacitor and part
Crystal oscillator etc., also, above element can not normal work when, had a strong impact on the functional reliability of on-Line Monitor Device.Therefore will
On-Line Monitor Device is placed in the incubator with thermal-collecting tube, and the temperature inside on-Line Monitor Device incubator is improved by thermal-collecting tube
Degree, and then improve the reliability of on-Line Monitor Device.Existing thermal-collecting tube typically uses water as heat transfer medium, to field
When on-Line Monitor Device is safeguarded, it is inconvenient that thermal-collecting tube is safeguarded, and the water freezing meeting frost heave in the case of without sunlight, damages thermal-arrest
Pipe；And the thermal-collecting tube of air dielectric is used, because the thermal capacity of air is smaller, convection effects are poor, and transmission heat ability is relatively low；
And existing thermal-collecting tube can be influenceed using the diversion mode of insertion, which by temperature, the convection effects when temperature difference is relatively low
Poor, heat caused by thermal-collecting tube is difficult to introduce in incubator.
The content of the invention
It is poor the invention aims to solve existing thermal-collecting tube convection effects, its gather heat can not timely by
A kind of the problem of being incorporated into incubator, it is proposed that low temperature environment day illuminated heat collector.
A kind of low temperature environment day illuminated heat collector of the present invention, the heat collector include vacuum heat collection pipe, connection
Joint, deflector and guide shell；
The vacuum heat collection pipe is used for the heat for collecting solar energy, and jointing is cylindrical shape, and wraps up vacuum heat collection pipe
Top, jointing be used for vacuum heat collection pipe is connected with incubator；
The guide shell is arranged on outside vacuum heat collection pipe opening portion, and guide shell is connected surrounding for joint；Guide shell it is another
One end extends to the inside of incubator；
The deflector is arranged on vacuum heat-collecting tube cavity, and one end of deflector is fixed on the bottom of guide shell, deflector
The other end extend to the inside of vacuum heat collection pipe；The width of the deflector is identical with the internal diameter of vacuum heat collection pipe；
Deflector includes heat-conducting plate and thermal insulation board；
Heat-conducting plate and thermal insulation board are fixed together by way of crimping or pasting；
The direction that the heat-conducting plate is set is towards sunlit direction, and the direction that thermal insulation board is set is to be shone backwards to sunlight
The direction penetrated.
The present invention the course of work be：After sunlight-illuminated vacuum thermal-collecting tube, the sunny slope and deflector of vacuum heat collection pipe
Between air by sunlight heats temperature raise；Because deflector has guide functions, also, the elevated atmospheric density of temperature
Diminish, therefore the elevated air of temperature rises to form ascending air and enter guide shell, then ascending air enters along guide shell
Inside incubator；It is temperature-resistant that air between the opaco and deflector of vacuum heat collection pipe is not affected by sunlight heats, i.e. air
Pressure is constant, but causes atmospheric pressure between the sunny slope of vacuum heat collection pipe and deflector because ascending air enters guide shell
It is strong to reduce, therefore the air between the opaco and deflector of vacuum heat collection pipe can be to the sunny slope and deflector of vacuum heat collection pipe
Between flow, and supplemented by the air inside incubator, so as to complete convection circulation.
The beneficial effects of the invention are as follows in the presence of deflector and guide shell, the convection effects of vacuum heat collection pipe interior air-flow
Greatly enhance so that the heat of vacuum heat collection pipe collection timely can be incorporated into incubator, so as to add vacuum heat-collecting
The Heat-collecting effect of pipe；And the present invention is simple in construction, reliability is high.
