Abstract
The utility model discloses a novel transformer cooling device which comprises a first cooling fan, a second cooling fan, a water curtain, a first alternating current contactor, a second alternating current contactor, a divider resistor, a fuse and an option switch. The first cooling fan and the second cooling fan are arranged at the bottom of a transformer side by side, the water curtain is arranged at the upper end of the second cooling fan, a first port of the option switch is connected with one end of the divider resistor, a second port of the option switch is connected with one end of a coil of the first alternating current contactor, and a third port of the option switch is connected with one end of a coil of the second alternating current contactor. The novel transformer cooling device is simple in structure, convenient to install, low in cost, capable of manually controlling the cooling intensity of the transformer through the option switch, and suitable for being used in small-scale factories or families.
Description
Technical field
The utility model relates to a kind of electric power cooling device, relates in particular to a kind of novel transformer cooling device.
Background technology
Develop rapidly along with China's electric utility, power transformer be send out, one of the visual plant in defeated, change, distribution system, its performance, quality are directly connected to reliability and the operation benefits of power system operation, and the safe and reliable operation of power transformer is the basic guarantee of the normal operation of electric power system.At present, the cooling device that also has many transformers because volume is large, complicated operation, poor anti jamming capability, also brought very big inconvenience for the use of engineering site.
The utility model content
The purpose of this utility model just is to provide in order to address the above problem a kind of a kind of novel transformer cooling device of manual control intensity of cooling.
The utility model is achieved through the following technical solutions above-mentioned purpose:
the utility model comprises the first cooling fan, the second cooling fan, cascade, the first A.C. contactor, the second A.C. contactor, divider resistance and selector switch, described the first cooling fan and described the second cooling fan are arranged side by side the bottom at transformer, described cascade is arranged on described the second cooling fan upper end, described selector switch the first port is connected with an end of described divider resistance, described selector switch the second port is connected with an end of the coil of described the first A.C. contactor, the 3rd port of described selector switch is connected with an end of the coil of described the second A.C. contactor.
Further, each power input is provided with fuse.
Further, the coil of the coil of described the first A.C. contactor and described the second A.C. contactor series connection.
The beneficial effects of the utility model are:
The utility model is simple in structure, and is easy for installation, with low cost, can, by the intensity of cooling of the manual control transformer of described selector switch, be suitable for the use of semiworks or family.
The accompanying drawing explanation
Fig. 1 is the utility model general structure position view.
Fig. 2 is circuit principle structure sketch of the present utility model.
In figure: FU1-fuse, FU2-fuse, FU3-fuse, FU4-fuse, FU5-fuse, the FU6-fuse, FU7-fuse, KM1-the first A.C. contactor, KM2-the second A.C. contactor, the R-divider resistance, M1-the first cooling fan, M2-the second cooling fan, SA-selector switch.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
the utility model comprises the first cooling fan M1, the second cooling fan M2, cascade, the first A.C. contactor KM1, the second A.C. contactor KM2, divider resistance R and selector switch SA, the first cooling fan M1 and the second cooling fan M2 are arranged side by side the bottom at transformer, cascade is arranged on the second cooling fan M2 upper end, selector switch SA the first port is connected with the end of divider resistance R, selector switch SA the second port is connected with an end of the coil of the first A.C. contactor KM1, the 3rd port of selector switch SA is connected with an end of the coil of the second A.C. contactor KM2.Power input is respectively arranged with fuse FU1, FU2, FU3, FU4, FU5, FU6, FU7.The coil series connection of the coil KM1 of the first A.C. contactor and the second A.C. contactor KM2.
Operation principle of the present utility model is: when ambient temperature while not being very high, the user is placed in left end as shown in Figure 2 by selector switch, only have the coil of the first A.C. contactor KM1 charged this moment, the coil of the second A.C. contactor KM2 is not charged, the main contacts closure of the first A.C. contactor KM1, the main contacts of the second A.C. contactor KM2 disconnects, the first cooling fan M1 work, and the second cooling fan M2 does not work; When ambient temperature is higher, the user is placed in right-hand member as shown in Figure 2 by selector switch, the coil of the first A.C. contactor KM1 and the second A.C. contactor KM2 is all charged, the main contacts of the first A.C. contactor KM1 and the second A.C. contactor KM2 is all closed, and the first cooling fan M1 and the second cooling fan M2 are in running order.The effect of divider resistance R is dividing potential drop protection control circuit.As shown in Figure 1, cascade is placed in the cooling fan upper end, because the maximum temperature of water is generally 100 degrees centigrade, so, when cooling fan is worked, utilize steam upwards can increase cooling effect.
