Abstract
The invention discloses an instant outage alarm. The instant outage alarm is characterized in that an alternating current contactor KM1, an audible and visual alarm B and a power source D providing direct current working voltage for the audible and visual alarm B are included, the audible and visual alarm B is connected into the power source D, a normally open contact KM1-1 of the alternating current contactor KM1 is connected to the circuit in series, and a switch KF is further installed on the circuit. The instant outage alarm has the advantages that the instant outage alarm is easy to manufacture, low in cost, high in stability and convenient to install; when the instant outage (power supply is restored immediately after the instant outage, and the outage time is larger than or equal to 0.2 second) of a power grid is monitored, the alarm with power supplied by a storage battery gives out a signal, the alarming is stopped until a person comes to tour off the alarm ( restore monitoring) or the electricity of the storage battery is used up so that related personnel can conveniently find the outage in time, and thus corresponding measures can be taken in time.
Description
Technical field
The present invention relates to a kind of alarm, be specifically related to a kind of instant cut-off alarm, belong to energy monitoring apparatus technical field.
Background technology
Due to supply line's fault; reclosing function in the protective device of power supply unit can be closed a floodgate rapidly and be restored electricity after generation transient fault circuit breaker trip; its actuation time is quite short; operator on duty may can not find once to have a power failure, though be transient-power failure, the equipment of some electricity consumptions can be out of service; if in unproductive time; do not have equipment operator, equipment will be in dead status always, will impact production or equipment.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of stability strong, be convenient to install, there is instantaneous power failure after can send the instant cut-off alarm of alerting signal in time.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of instant cut-off alarm, it is characterized in that, comprise: A.C. contactor KM1, audible-visual annunciator B and provide the power supply D of direct-current working volts for aforementioned audible-visual annunciator B, aforementioned audible-visual annunciator B is connected in power supply D, and the normally open contact KM1-1 of A.C. contactor KM1 is connected on this circuit.
Aforesaid instant cut-off alarm, is characterized in that, aforementioned circuit is also provided with K switch F.
Aforesaid instant cut-off alarm, is characterized in that, aforementioned power source D is the direct current cabinet battery in accumulator or switchgear building.
Usefulness of the present invention is: make simple, cost is low, and stability is strong, is convenient to install; (restore electricity immediately again after instant cut-off monitoring when instant cut-off appears in electrical network, power-off time >=0.2 second), signal is sent by battery-driven alarm, until have people come shutdown (Restoration monitoring) or accumulator electric-quantity exhaust rear just can stop alarm, be convenient to related personnel's Timeliness coverage and stopped electricity, thus corresponding measure can be made in time.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of instant cut-off alarm of the present invention;
Fig. 2 is the schematic diagram be applied to by instant cut-off alarm of the present invention in monitored electrical network.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
With reference to Fig. 1, instant cut-off alarm of the present invention comprises: A.C. contactor KM1, audible-visual annunciator B and power supply D, and wherein, power supply D is used for providing direct-current working volts for audible-visual annunciator B, therefore audible-visual annunciator B is connected in power supply D; The normally open contact KM1-1 of A.C. contactor KM1 is connected on this circuit.
As the preferred scheme of one, with reference to Fig. 1, this circuit is also provided with K switch F, K switch F is used for the break-make of operation circuit electric current.
In the present invention, power supply D both can be accumulator, can also be the direct current cabinet battery in switchgear building.When selecting the direct current cabinet battery in switchgear building as power supply D, not only can save cost, and avoid the trouble regularly charged a battery.
Instant cut-off alarm of the present invention, its principle of work is:
Be energized to A.C. contactor KM1 with the power supply in the electrical network that will monitor, when A.C. contactor KM1 adhesive, the normally open contact KM1-1 of A.C. contactor KM1 disconnects, audible-visual annunciator B power-off; When A.C. contactor KM1 dead electricity and grid cut-off, A.C. contactor KM1 disconnects, and the normally open contact KM1-1 of A.C. contactor KM1 closes, and audible-visual annunciator B energising sends blow a whistle warning and glittering light.
See figures.1.and.2, the step be applied in monitored electrical network by instant cut-off alarm of the present invention is as follows:
1, the A.C. contactor KM1 in instant cut-off alarm is accessed in the electrical network that will monitor, then audible-visual annunciator B is accessed power supply D, then audible-visual annunciator B is connected with the normally open contact KM1-1 of A.C. contactor KM1.
2, after connecting, if K switch F is when to open, audible-visual annunciator B can send to blow a whistle and report to the police and glittering light, now first presses the button SB2, and alarm starts monitoring operation.
If 3 there is power-off, audible-visual annunciator B can send blow a whistle warning and glittering light, press the button SB2 again, alarm returns to not only monitoring and runs and (restore electricity after instant cut-off but also immediately, power-off time >=0.2 second), if press the button SB2 cannot recover, illustrate that electrical network is not instant cut-off but continues to have a power failure, now K switch F is got to off-position and report to the police by the power consumption of power supply D to the greatest extent to prevent audible-visual annunciator B from blowing a whistle.
4, regularly (such as 1 month) presses the button SB1 and detects, if audible-visual annunciator B blows a whistle, sound diminishes, and illustrates that power supply D is under-voltage, please charges to power supply D in time.
Instant cut-off alarm of the present invention, its monitoring voltage can be 220V or 380V.Power supply D can be 9V, 12V, 24V, 36V etc.To change voltage, as long as the model of the A.C. contactor KM1 in equipment and audible-visual annunciator B is consistent with applied voltage.
As can be seen here, instant cut-off alarm of the present invention makes simple, and cost is low, and stability is strong, is convenient to install, is applicable to the monitoring of the place electric system such as factory, communication base station, computer house, workshop.
It should be noted that, above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
