Abstract
The utility model discloses a switch cabinet which comprises a switch cabinet body. An instrument board is arranged at the upper portion of the front of the cabinet body, an upper ventilating door is arranged at the upper portion of the back of the cabinet body, a back door is arranged at the lower portion of the back of the cabinet body, a plurality of exhaust fans are mounted on the upper ventilating door, and the lower portion of the back door is provided with a plurality of return air inlets. A controller is mounted on the instrument board, a temperature sensor is mounted in the cabinet body, and the controller is respectively and electrically connected with the temperature sensor and the plurality of exhaust fans. When the temperature sensor detects that the temperature in the cabinet body exceeds a set value, the controller enables the plurality of exhaust fans to run simultaneously. When the temperature sensor detects that the temperature in the cabinet body is lower than the set value, the controller enables the plurality of exhaust fans to stop running. The plurality of return air inlets can be arranged at the lower portion of the front of the cabinet body. A temperature displayer can be further connected onto the controller. The switch cabinet has good heat dissipation effect, and improvement of the running reliability of the switch cabinet and prolonging of the service life of instruments are facilitated.
Description
Technical field
The utility model relates to switch cubicle.
Background technology
Existing high and low voltage switch cabinet generally is made up of cabinet, isolating switch, circuit breaker, current transformer, measuring instrument, indicator light etc., in order to improve the fail safe of switch cubicle; The exposed face of cabinet generally all hides through door, and switch cubicle is in running, and the various device in the switch cubicle can generate heat; Existing switch cubicle is with end face ventilating opening to be set and to dispel the heat by cross-ventilation through ventilating opening is set on the air door of cabinet back, but China southern summer, ambient temperature is higher; This cross-ventilation mode radiating effect that leans on is relatively poor; Can make the scope of the working temperature overshoot in the switch cubicle, reduce the switch cubicle reliability of operation, cause the measuring instrument cisco unity malfunction; Reduce the useful life of measuring instrument, or accident such as switch cubicle generation misoperation.
The utility model content
The technical problem that the utility model will solve provides a kind of switch cubicle, its good heat dissipation effect, the useful life that helps improving switch cubicle reliability of operation and each instrument.
For achieving the above object, the technical scheme of the utility model is: a kind of switch cubicle comprises switch cabinet body; The top of cabinet front is provided with instrument board; The top of cabinet back is provided with air door, and the bottom of cabinet back is provided with the back door, and described going up on the air door is equipped with a plurality of ventilating fans; The bottom at described back door is provided with a plurality of return air inlets; On the described instrument board controller is housed, temperature sensor is housed in the cabinet, controller is electrically connected with temperature sensor and described a plurality of ventilating fan respectively; Controller started a plurality of ventilating fans and turns round simultaneously when temperature surpassed set point in temperature sensor detects cabinet, and controller stopped a plurality of ventilating fans runnings when temperature was lower than set point in temperature sensor detects cabinet.
Further, the bottom of said cabinet front is provided with a plurality of return air inlets, improves the convection effects of air.
Further, also connect a temperature indicator on the described controller, convenient monitoring to working temperature in the cabinet.
The utility model is equipped with temperature sensor owing on the last air door a plurality of ventilating fans are housed in the cabinet, controller is housed on the instrument board; Controller is electrically connected with temperature sensor and described a plurality of ventilating fan respectively, in case when the working temperature in the cabinet surpassed set point, controller will start a plurality of ventilating fans and turn round simultaneously; Air-flow to cabinet carries out forced circulation, so just can be to accelerating heat radiation in the cabinet, and radiating effect improves greatly; Can prevent the work of switch cubicle overtemperature; Guarantee the measuring instrument operate as normal, prolong the useful life of measuring instrument, help improving the switch cubicle reliability of operation.
On the other hand, controller will stop a plurality of ventilating fan runnings when temperature was lower than set point in temperature sensor detects cabinet, avoided the generation of unnecessary energy consumption.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the rearview of Fig. 1;
Fig. 3 is the utility model ventilating fan running control principle figure.
Embodiment
Below in conjunction with accompanying drawing and concrete execution mode the utility model is done further explain.
Fig. 1, shown in Figure 2, a kind of switch cubicle comprises switch cabinet body 1; The top of cabinet 1 front is provided with instrument board 2, and the top of cabinet 1 back is provided with air door 3, and the bottom of cabinet 1 back is provided with two fan back doors 4,5; The described bottom of a plurality of ventilating fans 6 being housed on the air door 3 and being provided with a plurality of exhaust outlets 31, two fan back doors 4,5 of going up is provided with a plurality of return air inlets 41,51, on the described instrument board 2 controller 7 is housed; Temperature sensor 8 is housed in the cabinet 1; Controller 7 is electrically connected with temperature sensor 8 and described a plurality of ventilating fans 6 respectively, and the bottom of cabinet 1 front also is provided with a plurality of return air inlets 11, also connects a temperature indicator 9 on the described controller 7.
Fig. 3 further specifies the control principle of a plurality of ventilating fan 6 runnings; When temperature surpasses set point in temperature sensor 8 detects cabinet 1; Controller 7 is connected a plurality of ventilating fans 6 after comparison a plurality of ventilating fans 6 of power initiation turn round simultaneously, to carrying out the forced-air circulation cooling in the cabinet, improve radiating effect; When temperature is lower than set point in temperature sensor 8 detects cabinet 1; The power supply of controller 7 a plurality of ventilating fans 6 of cut-out after comparison stops the running of a plurality of ventilating fans 6, saves energy consumption, also can observe the working temperature in the cabinet 1 through temperature indicator 9.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection range of this case.
Claims (3)
