<5> drying control device is that integrated pressure, control of temperature and humidity are integrated, and can judge and start respective element according to each transducer, completes dry.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model main transformer respirator solar energy automatic drying system.
In figure: 1 three-way pipe, 2 seal covers, 3 silica gel storage chambers, 4 ring heaters, 5 lubricating cups, 6 interior humidity sensors, 7 drying control devices, 8 outer humidity sensors, 9 storage batterys, 10 controller for solar, 11 terminal boxes, 12 photovoltaic modulies, 13 three-way magnetic valves, 14 pressure sensors, 15 temperature sensors.
Embodiment
As shown in Figure 1, the utility model main transformer respirator solar energy automatic drying system, comprises main transformer respirator, and main transformer respirator is made up of lubricating cup 5, silica gel storage chamber 3, seal cover 2 with three-way pipe 1, also comprises solar powered unit and drying control unit; Solar powered unit is connected to form successively by photovoltaic module 12, terminal box 11, controller for solar 10, storage battery 9; Drying control unit is by drying control device 7 connecting tee electromagnetically operated valve 13, ring heater 4(built-in temperature sensor simultaneously, therefore not shown) and transducer composition, three-way magnetic valve is placed in three-way pipe place, and ring heater is placed in silica gel storage chamber bottom; Transducer comprises outer humidity sensor 8, interior humidity sensor 6, temperature sensor and pressure sensor 14, outer humidity sensor is placed in open air, interior humidity sensor is placed in the pneumostome place between lubricating cup and silica gel storage chamber, temperature sensor 15 is placed in ring heater, and pressure sensor is placed in the oil tank of transformer connector of three-way pipe; Controller for solar connects drying control device.
Native system operation principle
System Working Principle is as follows: when photovoltaic module absorbs solar energy, by terminal box, the electric energy being converted to is stored in storage battery by controller for solar, as the power supply of drying control device, three-way magnetic valve and ring heater.When external environment condition humidity hour, detect the moisture of respirator interior, if moisture is larger, illustrate that silica gel (hygroscopic material) is saturated, absorption steam cannot remain valid, likely jeopardize the operation of main transformer, now drying control device starts ring heater and three-way magnetic valve, by respirator and main transformer isolation, be communicated with atmosphere and start and heat, when making moisture, heating is reduced to after lower numerical value, the interior humidity sensor initial condition that stops heating and recovering three-way magnetic valve to drying control device of signaling (is communicated with main transformer, with isolated from atmosphere), complete silica gel automatic drying process.In the time that outside moisture is larger, do not start drying control unit, prevent that silica gel makes moist in heating.Between main transformer and three-way magnetic valve, be provided with pressure sensor, open three-way magnetic valve according to sensor signal, with regulating oil tank internal pressure, prevent the excessive transformer tripping that causes of tank pressure.
The native system course of work
Photovoltaic module absorbs sunlight by opto-electronic conversion from nature, through terminal box and controller for solar by electrical power storage in storage battery, as system power supply.When outer humidity sensor detects that ambient humidity is less, explanation can be dried (ambient humidity is larger may cause in drier drying course again absorbing moisture); Interior humidity sensor detects the moisture of respirator interior, if when inner moisture is larger, illustrates that drier is saturated, ground absorbing moisture cannot remain valid, now start the ring heater with temperature control, and three-way magnetic valve action, closed oil tank of transformer connector is also opened atmosphere connector.Heater is spent left and right heat drying agent (silica gel) in constant temperature 100, in case burn drier, the moisture after heating is discharged respirator from atmosphere connector.When interior humidity sensor detects that respirator interior humidity is less, illustrate dry completely, stop heating, recover the reset condition of three-way magnetic valve, by respirator and the connection of main transformer fuel tank.Oil tank of transformer connector arranges pressure sensor, can prevent that excessive cannot the breathing of tank pressure from causing that the even fuel tank that trips expands, is out of shape.Meanwhile, outer humidity sensor detects external environment condition humidity, the poor effect dry respirator of extreme wet weather such as can prevent from raining time.
