And then fire incident is developed into, it is further improved.
Utility model content
The purpose of this utility model is to provide a kind of blower fan rotor main electrical scheme case device for monitoring temperature, sent out by detecting
Electric machine rotor main electrical scheme case internal temperature, the protective loop of blower fan unit is cut off rapidly in Initial Stage of Fire.
Embodiment of the present utility model provides a kind of blower fan rotor main electrical scheme case device for monitoring temperature, including is connected on
Temperature detect switch (TDS) on blower fan protective loop, temperature detect switch (TDS) includes being built in the of stator main electrical scheme case and rotor main junction box respectively
One temperature detect switch (TDS) and the second temperature detect switch (TDS)；First temperature detect switch (TDS) and the second temperature detect switch (TDS) are used to detect rotor main electrical scheme case in real time
Internal temperature, if temperature exceedes setting value, temperature detecting module inner contact is disconnected, and blower fan master control system is input to cut
The 24V high level signals of system, so that master control system is detected after the 24V dropouts, by controlling pitch-controlled system and frequency converter
System, realizes unit orderly closedown.
Further, the metal capping of the first temperature detect switch (TDS) and the second temperature detect switch (TDS) is adjacent to stator main electrical scheme case and rotor respectively
The mounting surface of main electrical scheme case is installed, the temperature-sensitive oil surface heat conductive silica gel of the first temperature detect switch (TDS) and the second temperature detect switch (TDS).
The beneficial effects of the utility model are compared with prior art：By increasing temperature control inside rotor main electrical scheme case
Switch, can trigger before cable ignites abnormal high temperature, tripping protection loop, protection box house is endangered from fire in casing
Evil, and then avoid complete machine serious accident on fire from occurring.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model blower fan rotor main electrical scheme case device for monitoring temperature.
Embodiment
The utility model is described in detail shown each embodiment below in conjunction with the accompanying drawings, but it should explanation,
These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works
Energy, method or equivalent transformation or replacement in structure, are belonged within protection domain of the present utility model.
Join shown in Fig. 1, present embodiments provide the temperature detect switch (TDS) including being connected on blower fan protective loop, temperature detect switch (TDS) bag
Include the first temperature detect switch (TDS) 11 and the second temperature detect switch (TDS) 21 for being built in stator main electrical scheme case 1 and rotor main junction box 2 respectively.
Temperature detect switch (TDS) in the present embodiment have performance stabilization, precision height, small volume, amount light, reliability height, long lifespan,
The features such as sorrow is small is done to radio, rotor main electrical scheme case internal temperature can be detected in real time, if temperature exceedes setting value, temperature
Spend detection module inner contact to disconnect, now cut the 24V high level signals for being input to fan master control system, master control system detection
To after the 24V dropouts, by controlling pitch-controlled system and frequency convertor system, unit orderly closedown is realized.The temperature control device energy
Enough monitoring blower fan rotor main electrical scheme case internal temperatures in real time, it is to avoid rotor main electrical scheme case and other auxiliary connection casees have spiral shell
Bolt torque, which loosens, causes unit risk on fire, can trigger in casing before cable ignites abnormal high temperature, tripping protection loop,
Box house is protected from fire hazard, and then avoids complete machine serious accident on fire from occurring.
In the present embodiment, the metal capping of the first temperature detect switch (TDS) 11 and the second temperature detect switch (TDS) 21 is adjacent to stator master and connect respectively
Line case 1 and the mounting surface of rotor main junction box 2 are installed, to ensure temperature-sensitive effect, the first temperature detect switch (TDS) 11 and the second temperature detect switch (TDS)
The similar heat-conducting medium of 21 temperature-sensitive oil surface heat conductive silica gel or other performance.
The a series of tool described in detail only for feasibility embodiment of the present utility model of those listed above
Body illustrates that they are simultaneously not used to limit protection domain of the present utility model, all to be made without departing from the utility model skill spirit
Equivalent implementations or change should be included within protection domain of the present utility model.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.
