Abstract
The utility model relates to an electrical cabinet, in particular to a temperature control protection apparatus for an electrical cabinet, comprising a blower fan arranged in a side door of the cabinet body, characterized by also comprising a temperature sensor, a temperature controller and an intermediate relay, wherein the signal output end of the temperature sensor is connected with the signal input end of the temperature controller, the signal output end of the temperature controller is connected with the signal input end of the intermediate relay, and the signal output end of the intermediate relay is connected with the blower fan in the side door of the cabinet body. Compared with the prior art, inside the electrical cabinet there is provided the temperature control protection apparatus, thereby effectively preventing components in the electrical cabinet from being damaged, and prolonging the service life of the electrical cabinet.
Description
Technical field
The utility model relates to a kind of regulator cubicle, a kind of specifically regulator cubicle temperature control protector.
Background technology
Existing regulator cubicle is because design is unreasonable, and some regulator cubicles do not have thermal window, though some has thermal window; But too small openings is when summer temp is too high, owing to increasing progressively rapidly of outdoor temperature rising and masses' productive life power load; The indoor temperature of regulator cubicle; Generally all surpass 70 degree, the long-time use may make inner circuit elements device burn out later, and causing regulator cubicle to swing machine can't use.
Summary of the invention
The utility model provides a kind of regulator cubicle temperature control protector in order to overcome the deficiency of prior art.
To achieve these goals; The utility model has designed a kind of regulator cubicle temperature control protector, comprises the blower fan that is arranged in the cabinet side door, it is characterized in that: also comprise a temperature sensor; A temperature controller and an auxiliary relay; The signal output part of said temperature sensor connects the signal input part of temperature controller, and the signal output part of temperature controller connects the signal input part of auxiliary relay, and the signal output part of auxiliary relay is connected with the interior blower fan of cabinet side door.
The utility model is compared with prior art, and the temperature control protector is set in regulator cubicle, has effectively avoided the damage of components and parts in the regulator cubicle, has prolonged the useful life of regulator cubicle.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the circuit of the utility model connects block diagram.
Referring to Fig. 1 and Fig. 2,1 is blower fan; 2 is temperature sensor; 3 is temperature controller; 4 is auxiliary relay; 5 is cabinet.
?
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2; The utility model comprises the blower fan 1 that is arranged in cabinet 5 side doors; Also comprise 2, one temperature controllers 3 of a temperature sensor and an auxiliary relay 4, the signal output part of temperature sensor 2 connects the signal input part of temperature controller 3; The signal output part of temperature controller 3 connects the signal input part of auxiliary relay 4, and the signal output part of auxiliary relay 4 is connected with the interior blower fan 1 of cabinet side door.
Concrete workflow is following; Earlier through temperature controller 3 temperature upper limit in the rack is set, the temperature in rack surpasses higher limit, and temperature sensor 2 can be given temperature controller 3 with signal feedback; Break off through the contact switch of temperature controller 3 auxiliary relay 4; Thereby blower fan 1 is shut down, avoided the too high damage that causes components and parts of internal temperature, prolonged the useful life of regulator cubicle.
