Abstract
The utility model relates to a sound and light alarm of circuit break. The purpose of the utility model is to provide the sound and light alarm of circuit break with simple operation, convenience, reliability, and easy overhaul. The technical scheme of the utility model is that: the sound and light alarm of circuit break comprises an electromagnetic relay and an AC/DC switch power supply and is characterized in that: an AC side of the switch power supply is connected to a high voltage working circuit of the electromagnetic relay, and a DC side of the switch is in parallel connection with a storage battery and an alarm circuit. The sound and light alarm is suitable for alarm prompt of accidental break of the circuit, such as an instant alarm of circuit break caused by steeling of a cable at a construction site and an alarm prompt of abnormal break of electric appliance.
Description
Technical field
The utility model relates to a kind of alarm, especially a kind of audible-visual annunciator of circuit breaker.Be applicable to the alarm that the circuit accident opens circuit, be stolen like the building ground cable and cause the improper alarm that opens circuit of the instant alarming, the electrical appliance that open circuit.
Background technology
Flourish along with China's building trade, particularly each item engineering construction initial stage, three (seven) logical one flat after, when construction team did not formally march into the arena as yet in a large number, the construction cable phenomenon that is stolen was of common occurrence.Owing to supply the construction cable laying depth of large-scale movable equipment (like ram engine) generally not dark, when equipment was not constructed at night, be stolen like cable, have no sign.After being stolen, repair difficulty for the moment, not only incur loss through delay the duration, and cause abominable social influence, cause enormous economic loss.Therefore for guaranteeing the safety of construction cable, develop a kind of convenience, alarm is imperative reliably.
Summary of the invention
The technical matters that the utility model will solve is: to the problem of above-mentioned existence, a kind of audible-visual annunciator of simple, convenient reliable, the circuit breaker that is easy to overhaul is provided.
The technical scheme that the utility model adopted is: a kind of audible-visual annunciator of circuit breaker; Comprise electromagnetic relay and AC/DC Switching Power Supply; It is characterized in that: said Switching Power Supply AC side is connected to the high-pressure work circuit of electromagnetic relay, Switching Power Supply DC side parallel accumulator and warning circuit.
Said warning circuit is a hummer and SRE operating on low voltage circuit after alarm lamp is parallelly connected.
Said electromagnetic relay is a moving fault.
The beneficial effect of the utility model is: the utility model principle clear principle, easy-to-understand, cost of manufacture is low.This audible-visual annunciator belongs to plug and play type, install small and exquisite, simple to operate, be easy to maintenance repair.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model.
Embodiment
As shown in Figure 1, present embodiment comprises the moving fault electromagnetic relay of AC/DC type Switching Power Supply and 220V input, and wherein the AC side of Switching Power Supply is connected to the high-pressure work circuit of electromagnetic relay, and the DC side of Switching Power Supply is parallelly connected with accumulator U and warning circuit.Said warning circuit be hummer H with alarm lamp L parallel connection after connect with the operating on low voltage circuit of electromagnetic relay.
When input quantity (voltage) when reaching setting, electromagnetic type relay makes controlled output circuit conducting or disconnection.This device has been selected the electromagnetic type relay of 220V input.This relay is made up of iron core, coil, armature, contact reed etc.; As long as add certain voltage at the coil two ends; Will flow through certain electric current in the coil; Thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring under the effect of electromagnetic attracting force inhales to iron core, thereby drives the moving contact and stationary contact (normally opened contact) adhesive of armature.Behind coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return original position at the reacting force of spring, and moving contact and original stationary contact (normally closed contact) are discharged.Adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.For " often open, normally closed " contact of relay, can distinguish like this: be in the stationary contact of off-state when relay coil is not switched on, be called " normally opened contact "; The stationary contact that is in on-state is called " normally closed contact ".This routine relay has two strands of circuit, is operating on low voltage circuit and high-pressure work circuit.
The concrete working method of present embodiment: at first converting alternating current to supply accumulator (accumulator carries charge protector in this system) to charge direct current through Switching Power Supply is charge in batteries; Directly be connected to the high-pressure work circuit of relay simultaneously from the Switching Power Supply AC side; When the high-pressure work circuit is in channel status; Contactor coil KM produces galvanomagnetic effect, and auxiliary reclay KA breaks off, and relay operating on low voltage circuit often leaves; The alarm circuit of control is in off state, and audible-visual annunciator is not worked; When the high-pressure work circuit is in off state, (be stolen like cable), auxiliary reclay KA is closed, and relay operating on low voltage circuit is connected, and accumulator is the low pressure loop power supply, excites acoustic-optic alarm, thereby plays the warning effect of luminous and sounding type.
Present embodiment only needs disconnecting circuit when maintenance repair: can be acoustic luminous, then in proper working order like this device; Diminish like sound, accumulator is charged to get final product; If can not be acoustic luminous, only need to check operating circuit break-make situation failure judgement point at once with multimeter, can recover normal behind the replacing element.
Claims (3)
1. the audible-visual annunciator of a circuit breaker comprises electromagnetic relay and AC/DC Switching Power Supply, it is characterized in that: said Switching Power Supply AC side is connected to the high-pressure work circuit of electromagnetic relay, Switching Power Supply DC side parallel accumulator (U) and warning circuit.
2. the audible-visual annunciator of circuit breaker according to claim 1 is characterized in that: said warning circuit is the parallelly connected back with alarm lamp (L) of hummer (H) SRE operating on low voltage circuit.
