Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
An acoustic-optic alarm for the circuit breaker failure tripping operation of transformer station, comprises shell 1, control circuit 10, alarm 13, light-emitting diode display 2 and operating key.Wherein, control circuit 10 is connected with all parts, is arranged on by control circuit 10 on same circuit board and operates whole device to facilitate.Shell 1 uses aluminum alloy materials, changes into black through sandblasting anodic oxygen.
As shown in Figure 1, be provided with light-emitting diode display 2 and operating key before shell 1, wherein operating key comprises time-out audible alarm key 301 and complete machine reset key 302.Sound mouth 9 device is also provided with between time-out audible alarm key 301 and complete machine reset key 302.During plant running, time-out audible alarm key 301 and complete machine reset key 302 are in luminance, prompting machine normal operation.
The both sides of shell 1 are provided with the baffle plate with ventilation and heat mouth 8.This device is fixed on installation place by fixed hook 7, has radiator fan 12 dispelled the heat by ventilation and heat mouth 8 when device works, and ensures the normal operation of equipment.
