Embodiment
Below in conjunction with accompanying drawing the utility model structural principle and working principle are described in further detail.
Referring to Fig. 1,2; a kind of temperature protective device of wind-driven generator turn-key system comprises external temperature sensor 1, temperature collect module 2, master controller 3, master control temperature control modules 4, adds thermorelay 5, independent heater switch 6, air heater 7, heat radiation relay 8, cooling fan 9.External temperature sensor 1 is connected with temperature collect module 2, and temperature signal is passed to master controller 3 by Internal Bus, the action of the temperature control signals commander master control temperature control modules 4 of master controller 3, the heater switch 10 of master control temperature control modules 4 is connected with the coil 11 that adds thermorelay 5, the common 12 that adds thermorelay 5 connects heating power supply, adds thermorelay 5 normally-closed contacts 13 and is connected, is connected to air heater 7 with independent heater switch 6.Air heater 7 is answered in-built electrical heating wire 15 and fan 14, and electrical heating wire 15 is positioned at the air-out direction of air heater 7, and electrical heating wire 15 is used to heat, and heating back hot gas is blown out to space, turn-key system place by fan 14.The heat radiation switch 16 of master control temperature control modules 4 is connected with the coil 17 of heat radiation relay 8, and the common 18 of heat radiation relay 8 connects power supply, and its normally opened contact 19 is connected with cooling fan 9.Cooling fan 9 should be formed in parallel on circuit by blower fan 20 and blower fan 21, and its mounting point places the bottom and the top of master control cabinet respectively, in order to form cross-ventilation.
Working principle of the present utility model is:
First, the common that adds thermorelay 5 is connected to heating power supply, and the process normally-closed contact is connected with independent temperature 6 switches, when the master control system temperature is lower than the setting temperature of independent temperature switch 6, independent temperature switch 6 closures, give air heater 7 power supplies, control heater 7 gets electric startup, is the turn-key system heating.
