Description
Technical field
The utility model belongs to technical field of power systems, relates in particular to a kind of closed equipment moisture separating device.
Background technology
In the industry-by-industries such as electric power system and industry, a large amount of low-voltage electrical control appliances are all positioned over closed equipment inside.Poor sealing after using because enclosed casing is long-time; moisture easily enters and accumulation is for a long time difficult to discharge; cause internal unit to make moist; and when meeting certain condition, humidity, moisture and the casing temperature difference easily produce condensation; cause components and parts corrosion, the aging acceleration of burn into, material property reduce, the short-circuit of terminals; DC earthing occurs and cause protective relaying maloperation or tripping, the operation to electrical network, the control of equipment cause huge hidden danger.Existing moisture-reducing device starts heater in the time that humidity is larger, and because casing is airtight, the moisture being heated circulates, flows at box house, and cannot be discharged to outside casing, and does not consider the impact of outside moisture, drives damp poor effect.For this reason, some producers increase ventilation hole on casing, but this affects again heating effect, are also easily subject to outside moisture impact.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of design science reasonable, simple and practical, drive the respond well closed equipment moisture separating device of tide.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: closed equipment moisture separating device, comprise and drive damp controller and heater in casing and casing, drive damp controller connect and control inner sensor, outer sensor, air inlet electromagnetic valve, give vent to anger electromagnetically operated valve and air pump; Inner sensor is located in casing, and outer sensor is located in the collector box being in communication with the outside in casing; Air pump connects air inlet electromagnetic valve and the electromagnetically operated valve of giving vent to anger.
Driving damp controller connects and control heater.
Heater connects temperature and humidity controller and interior Temperature Humidity Sensor.
Drive the problem of damp poor effect for current closed equipment, inventor improves and has designed a kind of closed equipment moisture separating device on existing basis, this device has considered that external environment condition is on driving damp impact, keep original box sealing, in being provided with, outer two transducers, one is detected inner bin humidity, one is detected external environment condition humidity, after reaching set point, inner sensor starts heater, and judgement, more inner, outer moisture value, in the time that interior humidity value is greater than outer moisture, start electromagnetically operated valve and air pump, be outside drier gas by discharge duct by the air displacement in casing, in the time that being less than outside, interior humidity is failure to actuate.Meanwhile, condensation, ponding etc. becomes gas under the effect of heater, discharges outside casing by the circulatory system (electromagnetically operated valve, air pump), and guard box soma is dry.Application the utility model, the dry gas of each displacement can keep for a long time, until gas is replaced when environmental drying next time, the box house humidity moment is less than outer moisture, and in comparatively dry state.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model closed equipment moisture separating device the first execution mode.
Fig. 2 is the structural representation of the utility model closed equipment moisture separating device the second execution mode.
In figure: 1 drives damp controller, 2 heaters, 3 inner sensors, 4 outer sensors, 5 air inlet electromagnetic valves, 6 electromagnetically operated valves of giving vent to anger, 7 air pumps, 8 collector boxs, 9 interior Temperature Humidity Sensors, 10 temperature and humidity controllers, 11 casings
Embodiment
As shown in Figure 1, the first execution mode of the utility model closed equipment moisture separating device comprises and drives damp controller 1 and heater 2 in casing 11 and casing, drive damp controller 1 connect and control inner sensor 3, outer sensor 4, air inlet electromagnetic valve 5, give vent to anger electromagnetically operated valve 6 and air pump 7; Inner sensor is located in casing, and outer sensor is located in the collector box 8 that is in communication with the outside in casing (with box house air insulated, preventing that burn into is aging etc., can detect again outside moisture easily); Air pump connects air inlet electromagnetic valve and the electromagnetically operated valve of giving vent to anger.Wherein, driving damp controller connects and control heater.
The operation principle of the first execution mode: inner sensor detects casing interior humidity, outer sensor detects extraneous air humidity.In inner sensor detects casing, large (as 75%) of humidity, drives damp controller and starts heater, and compare with the humidity that outer sensor collects.If interior humidity is greater than outer moisture (as differing 5%) left and right, air inlet electromagnetic valve and the electromagnetically operated valve of giving vent to anger are opened, and air pump is started working, and by discharge duct, gas displacement larger interior humidity is become to outside comparatively dry gas.Meanwhile, condensation, ponding etc. becomes gas under the effect of heater, discharges outside casing by the circulatory system, and guard box soma is dry.If interior humidity is less than extraneous air humidity, only start heater.
Existing moisture separating device is temperature and humidity controller 10, is actually to start heater 2 by interior Temperature Humidity Sensor 9 (detection case in humidity) and drive tide, and it does not connect devices such as controlling air pump, electromagnetically operated valve.As shown in Figure 2, the second execution mode of the utility model closed equipment moisture separating device improves on this basis, install inner sensor 3 (humidity in detection case), outer sensor 4 (the outer humidity of detection case) additional, drive damp controller 1, air inlet electromagnetic valve 5, give vent to anger electromagnetically operated valve 6 and air pump 7 and pipeline etc.Now, former moisture separating device (temperature and humidity controller) works alone respectively with the damp controller that drives installing additional.
The operation principle of the second execution mode: interior Temperature Humidity Sensor 9 is placed in box house, detects casing interior humidity, and when large (as 75%) of humidity in casing being detected, temperature and humidity controller 10 starts heater 2.The humidity that inner sensor 3 and the outer sensor 4 installing additional collects compares, if interior humidity is less than outer moisture (establish certain difference, as differ 5%) left and right, is failure to actuate, and air inlet electromagnetic valve 5 and the electromagnetically operated valve of giving vent to anger, air pump 7 are not worked; If being greater than outer moisture, interior humidity (establishes certain difference, as differ 5%) left and right, air inlet electromagnetic valve 5 and the electromagnetically operated valve 6 of giving vent to anger are opened, and air pump 7 is started working, and by discharge duct, gas displacement larger interior humidity are become to outside comparatively dry gas.Meanwhile, condensation, ponding etc. becomes gas under the effect of heater, discharges outside casing by the circulatory system, and guard box soma is dry.In above-mentioned execution mode, discharge duct is introduced from the passage of electric power incoming line, air pump and electromagnetically operated valve normal condition are in closure, and seal is good, do not affect body structure and keep sealing, substitution gas can ensure to be dried each time, until gas is replaced when environmental drying, thereby ensure that closed equipment is always in dry state. next timeThis device automatically detects, controls, without manual intervention, and the problem that solution equipment makes moist up hill and dale.
