Abstract
The utility model discloses a fuse alarm device of a fixed switch cabinet, which is characterized in that a travel switch (5), a support frame (2) and a fuse (4) are sequentially fixed on an insulating plate (1), a conductive rod (3) is movably supported on the support frame (2), and a firing pin is arranged in the fuse (4). The utility model has the advantages that the firing pin is ejected out after the fuse is burnt out, the firing pin pushes the conductive rod to move towards the other end, the conductive rod conducts contacts of the travel switch, open contacts are closed, an alarm loop is conducted, and the burnt phase of the fuse is indicated. The utility model can visually and clearly show the failure position, eliminate the failure as soon as possible, shorten the power failure time, and improve the work efficiency.
Description
Technical field
The utility model relates to the fuse warning device of the fixed switch cubicle of a kind of electrical power distribution system.
Background technology
At rated voltage 12kV, 6kV, 3kV, in the three-phase alternating current 50Hz medium voltage electricity distribution system, the fixed switch cubicle complete set of equipments of extensive use.At present, in PT, the schemes such as using change of standing, generally prevent overcurrent as the main element of protecting PT and transformer, can not in time be found and change after the fuse blows, fault can not be got rid of early, thereby influenced the good operation of system with fuse.
The utility model content
The utility model is to report to the police rapidly after designing a kind of fuse blows at can not in time being found after the present fuse blows, and can indicate the fixed switch cubicle fuse warning device of fusing position.
The fixed switch cubicle fuse of the utility model warning device is to be fixed with travel switch, support and fuse on insulation board successively, and movable supporting has a conducted rod on the support, is provided with striker in the fuse.
The utility model fuse warning device striker after fuse blows ejects, and striker promotes conducted rod and moves to the other end, and conducted rod is with the contacting of travel switch, and it is closed to make war, and connects alarm circuit and indicating fuse fusing phase.Demonstration abort situation that can be simple and clear is fixed a breakdown as early as possible, shortens interruption duration, increases work efficiency.
Description of drawings
Structural representation when Fig. 1 does not move for the fixed switch cubicle fuse of the utility model warning device embodiment;
Fig. 2 is the structural representation after the fixed switch cubicle fuse of the utility model warning device embodiment action.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, insulation board 2, support 3, conducted rod 4, fuse 5, travel switch
As shown in the figure, the fixed switch cubicle fuse of the utility model warning device is to be fixed with travel switch 5, support 2 and fuse 4 on insulation board 1 successively, and movable supporting has a conducted rod 3 on the support 2, is provided with striker in the fuse 4.
After fuse 4 fusing, striker ejects, and pushes conducted rod 3 to travel switch 5 one sides, and with travel switch 5 contactings, connection signal loop, signal alarm notifying operation personnel.
Claims (1)
1. fixed switch cubicle fuse warning device is characterized in that: be fixed with travel switch (5), support (2) and fuse (4) on insulation board (1) successively, support (2) is gone up movable supporting a conducted rod (3), and fuse is provided with striker in (4).
