Abstract
The invention discloses a sound alarm system for an uninterruptable power supply. The sound alarm system comprises a UPS mainframe (1), a wire-inlet power supply (2), a wire-outlet power supply (3) of the UPS mainframe (1), an intermediate relay (4) and an alarm (5). The coil of the intermediate relay (4) is connected with the wire-inlet power supply (2). The outlet wire of the UPS mainframe (1) is connected with a normally-closed contact of the intermediate relay (4). The alarm (5) is connected with a main circuit which passes through the intermediate relay (4). The sound alarm system for the uninterruptable power supply provided by the invention controls the intermediate relay via the wire-inlet power supply and the wire-outlet power supply of the uninterruptable power supply to enable the alarm to alarm after the electric supply of the uninterruptable power supply is interrupted to remind an operating staff to switch a backup power or reduce the use of essential equipment, and store the important information to prevent the important information from being lost, and to timely inform the alarm information to the operating staff.
Description
Technical field
The invention belongs to safety means technical field, be specifically related to a kind of uninterrupted power supply power down warning system.
Background technology
Along with the arriving of informationized society, UPS main frame 1 is widely used in the links of PLC, information gathering, transmission, process, storage application, and its importance is constantly along with the importance of application improves day by day.UPS main frame 1(UninterruptiblePowerSystem/UninterruptiblePowerSupply), i.e. uninterrupted power supply, be that storage battery (mostly being plumbic acid maintenance-free storage battery) is connected with main frame, by modular circuits such as main frame inverters, direct current converted to the system equipment of civil power.Be mainly used in providing stable, continual supply of electric power to PLC, computer network system or other power electronic equipment.When civil power input is normal, UPS main frame 1 is supplied to load to use by after civil power voltage stabilizing, and UPS main frame 1 is now exactly an electric main pressurizer, and it also charges to self-contained battery simultaneously; When commercial power interruption (accident interruption), UPS main frame 1, immediately by the direct current energy of battery, continues supply 220V alternating current by the square normal load of inversion zero switch transition, load is maintained and normally works and protect load soft and hardware not to be damaged.Being a kind of containing energy storage device, take inverter as the uninterrupted power supply of the constant voltage constant frequency of chief component.But along with UPS main frame 1 apply constantly extensively, importance in the productive life of UPS main frame 1 seems particularly important, and the switching etc. that corresponding warning reminding operating personnel carry out stand-by power supply can not be carried out immediately after the commercial power interruption of UPS main frame 1, relevant preparation can not be carried out in advance, bring hidden danger to productive life greatly.
Summary of the invention
For above-mentioned weak point of the prior art, the object of the invention is the audible alarm system aiming to provide a kind of uninterrupted power supply, carrying out control by the power supply of uninterrupted power supply inlet wire and outlet to auxiliary relay makes alarm report to the police after uninterrupted power supply commercial power interruption, operating personnel are reminded to carry out the switching of stand-by power supply, or reduce the use of inessential equipment, preserve important information etc. and prevent loss, make warning message can teaching process personnel timely.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of audible alarm system of uninterrupted power supply, it is characterized in that: comprise UPS main frame, incoming power, UPS main frame outlet power supply, auxiliary relay and alarm, the coil of described auxiliary relay is connected on incoming power, the outlet of described UPS main frame is connected on the normally-closed contact of auxiliary relay, and described alarm is then connected on the main line of auxiliary relay normally-closed contact.
Specifically, electricity is had when UPS main frame carries out power supply, the coil of auxiliary relay obtains electric, the normally-closed contact of auxiliary relay becomes normally opened contact, and be connected to by the outlet of UPS main frame and auxiliary relay normally-closed contact put alarm because circuit disconnects and can not report to the police and glisten, otherwise, when the power down of UPS main frame incoming power, auxiliary relay coil is without electricity, normally-closed contact recovers, and the normally-closed contact being connected to the outlet of UPS main frame closes, the alarm be connected on this circuit obtains electric, and carry out reporting to the police and glistening, prompting and teaching process personnel carry out noting or taking appropriate measures timely.
The present invention has the following advantages relative to prior art:
(1), warning system provided by the present invention, overcome prior art under power-down conditions, operating personnel can not Timeliness coverage, gives to produce commander, office data etc. and bring hidden danger.
(2), audible alarm system provided by the present invention can remind operating personnel timely, solves greatly and causes system-down, loss of data etc. because of power down, and the very big security reliability that improve production, has stronger promotional value.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention, simple introduction is done below by the accompanying drawing used required in embodiment, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and the every other embodiment obtained, all belongs to scope.
A kind of audible alarm system of uninterrupted power supply as shown in Figure 1, it is characterized in that: comprise UPS main frame 1, incoming power 2, UPS main frame 1 outlet power supply 3, auxiliary relay 4 and alarm 5, the coil of described auxiliary relay 4 is connected on incoming power 2, the outlet of described UPS main frame 1 is connected on the normally-closed contact of auxiliary relay 4, and described alarm 5 is connected on the main line of auxiliary relay 4 normally-closed contact.
Specifically, electricity is had when UPS main frame 1 carries out power supply 2, the coil of auxiliary relay 4 obtains electric, the normally-closed contact of auxiliary relay 4 becomes normally opened contact, and be connected to by UPS main frame 1 outlet and auxiliary relay 4 normally-closed contact put alarm because circuit disconnects and can not report to the police and glisten, otherwise, when the power down of UPS main frame 1 incoming power 2, auxiliary relay 4 coil is without electricity, normally-closed contact recovers, and the normally-closed contact being connected to UPS main frame 1 outlet closes, the alarm be connected on this circuit obtains electric, and carry out reporting to the police and glistening, prompting and teaching process personnel carry out noting or taking appropriate measures timely.
