Description
Technical field
The utility model relates to a kind of power supply unit, especially a kind of power distribution cabinet running status display instrument fixture.
Background technology
In the prior art, known technology is that power distribution cabinet running status display instrument is for showing the state of the equipment of reference numeral, to observe the state of power distribution cabinet institute on-load, during ore deposit powers in the open at present, the lower equipment variation in hole is frequent, staff only has the operation conditions that could be obtained the lower equipment in hole by display instrument on power distribution cabinet timely, but because power distribution cabinet is arranged on stope periphery, apart from each other, once lose, just cannot understand the operation conditions of the lower equipment in hole timely, therefore there is potential safety hazard, this is the weak point existing for prior art.
Summary of the invention
The purpose of this utility model, be exactly for the deficiency existing for prior art, and a kind of technical scheme of power distribution cabinet running status display instrument fixture is provided, the device of the program, firmly can fix display instrument, and there is warning device, once display instrument is moved, just can send warning.
This programme is achieved by the following technical measures: a kind of power distribution cabinet running status display instrument fixture, include the box body with lid, it is characterized in that: on lid, be provided with the observation window for observing display instrument, box body is provided with display instrument fixed frame, the first travel switch is provided with in display instrument fixed frame, the first described travel switch is connected with the first relay, the normally opened contact of the first relay is connected with an alarm, the position fastened at lid and box body is provided with the second travel switch, second travel switch is connected with an illuminating lamp, illuminating lamp is in parallel with the second relay, normally-closed contact and the first stroke switch series of the second relay join.
Lid and box body are connected through the hinge.
The position that described box body and lid fasten is provided with groove, and the position that lid and box body fasten is provided with projection, and described groove mates with projection.
Second travel switch is arranged in described groove.
The first described relay and the second relay are auxiliary relay.
Described illuminating lamp is arranged on the bottom of box body, and illuminating lamp is LED.
Electro-insulating rubber layer is provided with inside described display instrument fixed frame.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to there being display instrument fixed frame to fix display instrument in this scenario, inside display instrument fixed frame, be provided with electro-insulating rubber layer, play the effect of insulation, and play cushioning effect, avoid display instrument fixed frame to damage display instrument; There is observation window can observe the display situation of display instrument, just can observe the situation of display instrument when not opening the lid, avoiding the complicated processes opened the lid; The position that described box body and lid fasten is provided with groove, and the position that lid and box body fasten is provided with projection, and described groove mates with projection, lid and box body well can be fixed like this, play the effect of waterproof; Described illuminating lamp is arranged on the bottom of box body, and illuminating lamp is LED, and the second travel switch is arranged in described groove, after opening the lid like this, the second travel switch closes, and illuminating lamp is bright, be convenient to operated by personnel's display instrument, illuminating lamp adopts LED, saves electric energy; During work, lid and box body are closed, and now the second travel switch disconnects, if display instrument is moved, then the first row field switch K1 closes, and the first relay obtains electric, and the normally opened contact of the first relay closes, and alarm obtains electric, sends warning; After lid is opened, the second travel switch closes, and illuminating lamp obtains electric bright, and the second relay obtains electric starting working, and the normally-closed contact of the second relay disconnects, now mobile display instrument, and alarm can not be sounded warning, this avoid false alarm.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
