Abstract
The utility model discloses a fire-fighting alarm power-off electric cabinet which includes a cabinet housing. A smoke sensing device which is arranged in the cabinet housing is electrically connected with an alarm; the alarm is electrically connected with a breaker; and the breaker receives an alarm signal from the alarm and then breaks off an energized circuit in the electric cabinet. When an inner element of the electric cabinet is on fire and produces smoke, the alarm can give an alarm in time, and cuts off an inner circuit of the electric cabinet, thus effectively preventing the further development of a fire hazard.
Description
Technical field
The utility model relates to the high voltage package production field, relates in particular to the fire protection warning electric cabinet that cuts off the power supply.
Background technology
When burning took place existing electric cabinet, the cabinet internal circuit can not in time be disconnected, and can not in time be learned, leads to further disaster easily, particularly to being far from the crowd, not having the electric cabinet of special messenger's nurse, the normal fire disaster that therefore leads to.
The utility model content
The purpose of this utility model provides the fire protection warning electric cabinet that cuts off the power supply.
The purpose of this utility model is to be achieved through the following technical solutions:
The utility model proposes the fire protection warning electric cabinet that cuts off the power supply, comprise the cabinet shell, the sense cigarette device that is arranged in the described cabinet shell is electrically connected alarm, and described alarm is electrically connected circuit breaker, and the alarm signal that described circuit breaker receives described alarm disconnects the interior power-on circuit of described electric cabinet.Described alarm embeds described cabinet enclosure by described cabinet cover top portion, and described sense cigarette device is installed on described alarm front end.Described cabinet cover top portion inboard is provided with the receiving space that sectional area reduces gradually, and described sense cigarette device is located at described receiving space inboard.Described circuit breaker is located at described cabinet shell lateral wall, and described circuit breaker contains relay, switch, and described relay receives to the signal of described alarm and controls described switch and disconnects, and described switch is arranged on the link circuit of described electric cabinet.
Electricity cabinet internal combustion, the space has a narrow range of temperature in the initial cabinet, as uses heat detection, wait to be burned to a fixed difference difference and could to report to the police.External power does not cut off in the burning, not only accelerates burning but also can cause the external circuit fire.Electricity cabinet shell body does not have heat insulation layer, and hyperthermia radiation easily causes inflammable gas, liquid, particulate, other material spontaneous combustion.The utility model top is gone up alarm is installed, and adopts " smoke detection ", and " circuit breaker " installed in the side, and electric cabinet shell body has heat insulation layer.As long as electric cabinet internal combustion smolders, to report to the police immediately and cut off external power, electric cabinet shell body does not conduct heat.
Beneficial effect: the utlity model has the function that burning is reported to the police, cut off external power supply, can prevent the fire upgrading.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is electric cabinet front view for the utility model fire protection warning cuts off the power supply;
Fig. 2 is electric cabinet vertical view for the utility model fire protection warning cuts off the power supply;
Fig. 3 is electric cabinet principle schematic for the utility model fire protection warning cuts off the power supply;
Among the figure: 1, cabinet shell; 4, alarm; 5, circuit breaker; 6, switch; 7, relay; 8, ring current line; 9, sense cigarette device.
Embodiment
As Fig. 1-3, the utility model proposes the fire protection warning electric cabinet that cuts off the power supply, comprise cabinet shell 1, the sense cigarette device 9 that is arranged in the cabinet shell 1 is electrically connected alarm 4, alarm 4 is electrically connected circuit breaker 5, and the alarm signal that circuit breaker 5 receives alarm 4 disconnects the power-on circuit in the electric cabinet.Alarm 4 embeds cabinet shell 1 inside by the cabinet cover top portion, and sense cigarette device 9 is installed on alarm 4 front ends.Cabinet shell 1 inside top is provided with the receiving space that sectional area reduces gradually, and sense cigarette device 9 is located at the receiving space inboard.Circuit breaker 4 is located at cabinet shell 1 lateral wall, and circuit breaker 4 contains relay 7, switch 6, and relay 7 receives to the signal of alarm 4 and control switch 6 disconnections, and switch 6 is arranged on the link circuit of electric cabinet.
The electricity cabinet top design side of being convex form adopts sense cigarette device 9 to connect alarm 4 and be installed on the cabinet cover top portion, and the heat-carrying flue dust that the electrical equipment burning produces flows to electric cabinet top under " thermal convection " effect.Electricity cabinet lateral surface is installed circuit breaker 5, sense cigarette device 9 detects flue dust, transmits signal to alarm 4, and the relay 7 when alarm 4 is reported to the police in circuit breaker 4 transmits signal, make relay 7 control switchs 6 disconnect the interior link circuit of electric cabinet, can avoid burning further to spread.
The utility model is not limited thereto execution mode, based on the related realization assembly of the utility model thought all in protection range of the present utility model.
