Abstract
The utility model discloses a signboard for preventing accidental operations of an air switch, and solves the problem that in the prior art signboards are not striking enough. The signboard comprises an air switch (1). A light emitting diode (6) is arranged on the panel of the air switch (1). The light emitting diode (6) is connected to a power supply (8) through a human body infrared detection sensor switch (7). The front side of the light emitting diode (6) is provided with a rear side glass frame (5), the front side of the rear side glass frame (5) is provided with an observing glass frame (3), a signboard slot (4) is arranged between the rear side glass frame (5) and the observing glass frame (3), and a signboard is movably inserted into the signboard slot (4). The signboard for preventing accidental operations of an air switch is especially suitable for applying to an air switch control screen of a transformer substation.
Description
Technical field
The utility model relates to the Sign Board on a kind of electric switch, particularly the Sign Board on the air switch of a large amount of intensive uses in a kind of electric power secondary system.
Background technology
Air switch is owing to have good arc extinguishing ability, and good cost performance is widely used in the low-voltage electrical system, particularly uses very extensive in the electrical secondary system of electric power system.Transformer station's station using electricity system is the key equipment that ensures the normal operation of electric power secondary system, in transformer station, be provided with many air switch control flows, the air switch control flow is provided with air switch sign board, be used for sign to prevent misoperation and wrong diagnosis, but these Sign Boards are eye-catching inadequately, misoperation often takes place in practical operation, causes the economic loss of electrical network.
Summary of the invention
The utility model provides a kind of fool proof Sign Board of air switch, has solved existing air switch sign board eye-catching problem inadequately.
The utility model is to solve above technical problem by the following technical programs:
A kind of fool proof Sign Board of air switch, comprise air switch, the panel of air switch is provided with light-emitting diode, light-emitting diode is communicated with power supply by human body infrared acquisition sensitive switch, be provided with the rear glass frame in the front side of light-emitting diode, be provided with the sight glass frame in the front side of rear glass frame, be provided with the Sign Board draw-in groove between rear glass frame and sight glass frame, activity is plugged with Sign Board in the Sign Board draw-in groove.
Human body infrared acquisition sensitive switch is arranged on the side panel of air switch.
Sign Board of the present utility model is made by the ticker tape that is convenient for changing, and dispose light-emitting diode and do background and illuminate usefulness, circuit of LED is very simple, need not facilities such as step-down rectifier, have lighting of human body infrared induction sensitive switch control light-emitting diode, prolonged the useful life of diode and unnecessary energy resource consumption.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of fool proof Sign Board of air switch, comprise air switch 1, the panel of air switch 1 is provided with light-emitting diode 6, light-emitting diode 6 is communicated with power supply 8 by human body infrared acquisition sensitive switch 7, be provided with rear glass frame 5 in the front side of light-emitting diode 6, be provided with sight glass frame 3 in the front side of rear glass frame 5, be provided with Sign Board draw-in groove 4 between rear glass frame 5 and sight glass frame 3, activity is plugged with Sign Board in Sign Board draw-in groove 4.
Human body infrared acquisition sensitive switch 7 is arranged on the side panel 2 of air switch 1.
As human body when the air switch, light-emitting diode will light, illuminate the sign brief note that covers on the light-emitting diode simultaneously, operating personnel will most clearly see the title of this air circuit and the information of control object, carry out the on or off operation of corresponding circuit then, reduced the probability of happening of misoperation wrong diagnosis electricity situation.
Claims (2)
