Abstract
The utility model relates to a kind of overvoltage protection device with warning function; comprise over-voltage protection module; its technical characteristics is: also comprise over-voltage monitoring module and alarm module; over-voltage monitoring module and over-voltage protection module are connected in parallel on electrical network three-phase circuit, and the output terminal of this over-voltage monitoring module is connected with alarm module.The utility model is reasonable in design; it increases over-voltage monitoring module and alarm module on the basis of existing overvoltage protection device; by over-voltage monitoring module, superpotential is carried out to Real-Time Monitoring, in the time reaching overvoltage protection working value, send and report to the police and point out staff by alarm module.This overvoltage protection device has not only been realized over-voltage protection function, and has realized warning function, has improved the promptness of power network overvoltage protection.
Description
Technical field
The utility model belongs to overvoltage protection device technical field, especially a kind of overvoltage protection device with warning function.
Background technology
Superpotential be electric system under given conditions, the abnormal voltage that occurs exceeding operating voltage raises, its insulation to power equipment forms test, too high superpotential can jeopardize the safe and reliable operation of electric system.Therefore,, according to various superpotential causes, research restriction, provides necessary protection, has great importance for Operation of Electric Systems.Existing overvoltage protection device only provides defencive function on the spot, can not and alarm, there is delay scene rush to repair risk.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of overvoltage protection device with warning function is provided, solve existing overvoltage protection device can not and the problem of alarm.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of overvoltage protection device with warning function; comprise over-voltage protection module; also comprise over-voltage monitoring module and alarm module, over-voltage monitoring module and over-voltage protection module are connected in parallel on electrical network three-phase circuit, and the output terminal of this over-voltage monitoring module is connected with alarm module.
And described over-voltage monitoring module comprises monitoring means and three voltage dividers, described monitoring means is connected on electrical network three-phase circuit by three voltage dividers, and the output terminal of described monitoring means is connected with alarm module.
And described alarm module comprises LED display and hummer, this LED display is all connected with over-voltage monitoring module with hummer.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design; it increases over-voltage monitoring module and alarm module on the basis of existing overvoltage protection device; by over-voltage monitoring module, superpotential is carried out to Real-Time Monitoring, in the time reaching overvoltage protection working value, send and report to the police and point out staff by alarm module.This overvoltage protection device has not only been realized over-voltage protection function, and has realized warning function, has improved the promptness of power network overvoltage protection.
Brief description of the drawings
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A kind of overvoltage protection device with warning function; as shown in Figure 1; comprise over-voltage protection module, over-voltage monitoring module and alarm module, over-voltage protection module and over-voltage monitoring module are connected in parallel on electrical network three-phase circuit, and the output terminal of this over-voltage monitoring module is connected with alarm module.Described over-voltage monitoring module comprises monitoring means and three voltage dividers, monitoring means is connected on electrical network three-phase circuit by three voltage dividers, this monitoring means is realized the monitoring analysis function to line voltage, the output terminal of monitoring means is connected with alarm module, and this alarm module comprises LED display and hummer.In the time that electrical network transfinites superpotential, over-voltage protection module is realized superpotential defencive function, and meanwhile, superpotential detection module sends warning message by alarm module.In the time that alarm module is reported to the police, can show current magnitude of voltage by LED display, and by the hummer warning of sounding.This overvoltage protection device can be pointed out staff in time by alarm module, has improved the promptness of power network overvoltage protection.
It is emphasized that; embodiment described in the utility model is illustrative; instead of determinate; therefore the utility model comprises and is not limited to the embodiment described in embodiment; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
