Abstract
The invention discloses a transformer substation outdoor terminal box. The transformer substation outdoor terminal box comprises a box bin and a box door. A dehumidifying circulating dryer, a condensation device, a heater and a temperature and humidity monitoring device are arranged in the box bin. The condensation device comprises a condensation chamber, a condensation sensor and a condensation controller. The dehumidifying circulating dryer is communicated with the condensation chamber. The heater and the condensation sensor are connected with the condensation controller separately. According to the transformer substation outdoor terminal box of the invention, damp air in the box bin is extracted into the condensation chamber for gas-water separator so as to realize the effect of air drying in the box bin.
Description
Technical field
The present invention relates to a kind of transformer station outdoor terminal box, relate to electric power system.
Background technology
Terminal box inner space is very compact, and for ensureing at high humidity local insulation level, assurance device reliably working, has higher requirement to moistureproof, anti-condensation in case.China adopts Automatic-heating dehumidifying controller to prevent condensation from having the history of more than ten years in terminal box, this heating and dehumidification controller is at moisture resistant, anti-condensation guarantee high-tension apparatus reliability service aspect serves positive role, but in the area application had, also there are some problems, such as: at southern plum rain season, sometimes the air humidity of terminal box inside is higher, the even existing dew condensation phenomenon in local in terminal box, because the condensation sensing station being arranged on box house does not reach the degree of condensation, or condensation transducer is for a long time by dust in air and gas attack, the sensitivity of transducer is affected, condensation controller can not start heater in time, cause the effect of condensation controller malfunctioning, threat is brought to the safety of switchgear.
Summary of the invention
Technical problem to be solved by this invention is exactly to adapt to distinct device, adjustable a kind of transformer station outdoor terminal box.
For solving the problems of the technologies described above, the present invention adopts following technical scheme, a kind of transformer station outdoor terminal box, comprise bin and chamber door, dehumidifying circular dryer, condensation device, heater and temperature humidity monitor is provided with in described bin, described condensation device comprises condensation room, condensation transducer and condensation controller, and described dehumidifying circular dryer is connected with condensation room, and heater, condensation transducer are connected with described condensation controller respectively.
Preferably, be also provided with the blower fan be connected with temperature humidity monitor in described bin, described bin is provided with airway.
Preferably, wire netting is provided with in described airway.
Preferably, the edge of opening of described bin is provided with vent board, and described vent board is provided with some grids.
Preferably, the top of described vent board and the top of described bin are equipped with rain cover.
Preferably, the distance between adjacent described grid is 1 ~ 3cm.
Preferably, metal graticule mesh is also provided with between described grid.
A kind of transformer station outdoor terminal box of the present invention, by dehumidifying circular dryer by the humid air in bin, is extracted into condensation room, carries out gas, water is separated, to reach the effect of bin inner air drying.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is a kind of transformer station outdoor terminal box structural representation of the present invention.
Embodiment
As shown in Figure 1, for a kind of transformer station outdoor terminal box of the present invention, comprise bin 1 and chamber door 12, dehumidifying circular dryer 7, condensation device, heater 11 and temperature humidity monitor 14 is provided with in described bin, described condensation device comprises condensation room 8, condensation transducer 9 and condensation controller 10, described dehumidifying circular dryer 7 is connected with condensation room 8, and heater 11, condensation transducer 9 are connected with described condensation controller 10 respectively.By dehumidifying circular dryer 7 by the humid air in bin 1, be extracted into condensation room 8, carry out air to be separated with the steam in air, steam in bin 1 is collected into described condensation room 8 by described dehumidifying circular dryer 7 in time, under described condensation controller 10 controls, progressively condense into the globule or ice crystal.Concrete, temperature humidity monitor 14 carries out temperature and humidity detection, and A, when natural temperature is greater than 20 DEG C, steam progressively condenses into the globule in condensation room 8, and the globule converges to ponding draining window, discharges bin 1; B, when natural temperature is less than 20 DEG C, steam, in condensation room 8, is progressively sublimated as ice crystal, the process of Here it is long-pending frost.Every long-pending frost continuously 120 minutes, this bin dehumidifier carries out the defrosting of 10 minutes automatically, and it is discharged bin 1 with the state of aqueous water; C, when bin 1 humidity is higher than 55%RH, bin dehumidifier is devoted oneself to work automatically; Humidity stops dehumidifier automatically lower than during 40%RH.When natural temperature is greater than 30 DEG C, ambient humidity is greater than 80%RH, within 24 hours, discharges the water yield from humid air and counts roughly 50ml-350ml.
Also be provided with the blower fan 6 be connected with temperature humidity monitor 14 in described bin 1, described bin is provided with airway 5.Increase blower fan 6 and airway, the mobility of air in described bin 1 can be increased further, reach and keep the inner dry effect of described bin 1 further.
The edge of opening of described bin 1 is provided with vent board 2, and described vent board 2 is provided with some grids 3.Institute's grid 3 is distributed on described vent board 2, and the distance stated between adjacent described grid 3 is 1 ~ 3 centimetre, can ventilate, and can prevent again toy from entering.Be provided with wire netting (not shown) in described airway 5, be provided with metal graticule mesh 4 between described grid 3, described metallized metal net and described metal graticule mesh 4 do not enter for preventing toy.
The top of described vent board 2 and the top of described bin 1 are equipped with rain cover 13, play rainproof effect.
