Description
Technical field
The utility model is related to a kind of fire-fighting equipment power self test circuits.
Background technology
Fire-fighting equipment power supply monitoring system be collection industrial computer technology, communication, electromagnetism interference, digital sensing technology and
Industrial field bus technology is in the intellectualizing system of one, using the signal transducer of a variety of high sensitivity, the fire-fighting to monitoring
Equipment power supply carries out 24 hours real-time automatic detectings, monitoring.By monitoring the electric current, voltage, working condition of fire-fighting equipment power supply,
To judge fire-fighting equipment power supply with the presence or absence of failures such as interruption of power supply, overvoltage, under-voltage, overcurrent, phase shortages, and carry out sound-light alarm
And record.The working condition of fire-fighting equipment power supply can be concentrated on the fire-fighting equipment power supply status monitor in fire protection control room
It showing, is handled in time after fault alarm, hidden danger of debugging makes fire-fighting equipment power supply be in normal operating conditions always,
The reliability service of fire-fighting equipment is ensured to the maximum extent.
But conventional fire-fighting equipment lacks self-checking function with power supply monitoring system, needs before periodically accrediting professional
It is monitored on the spot toward scene；To significantly increase the burden of enterprise, and general enterprises can not possibly be equipped with so
More professional technician, to often its be caused event occur in time during inspection the problem of discovery monitoring system
Barrier, influences its normal use.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of fire-fighting equipment power supplys having self-checking function
Self-checking circuit.
What the purpose of this utility model was realized in：
A kind of fire-fighting equipment power self test circuit, the circuit include three groups of mutual inductors, and three groups of mutual inductors cover respectively
Loaded on three-phase power line, the mutual inductor accesses the input of light-coupled isolation module after the controlled terminal of three relays respectively
End, the output end of subsequent light-coupled isolation module is grounded after indicator light respectively, is passed through after the control terminals of three relays is parallel with one another
Button, the circuits DC/DC are connected to accumulator.
Compared with prior art, the utility model has the beneficial effects that：
The utility model can be detected (ordinary person can operate) automatically by lower button, when breaking down
When, indicator light will be unable to light, to know that there are failures；Professional is sent to go to investigation again at this time, to greatly drop
Low cost.
Description of the drawings
Fig. 1 is a kind of circuit diagram of fire-fighting equipment power self test circuit of the utility model.
Specific implementation mode
Referring to Fig. 1, the utility model is related to a kind of fire-fighting equipment power self test circuit, the circuit includes three groups
Mutual inductor, three groups of mutual inductors are set on three-phase power line, controlled terminal of the mutual inductor respectively through three relays
Access the input terminal of light-coupled isolation module afterwards, the output end of subsequent light-coupled isolation module is grounded after indicator light respectively, three after
After the control terminal of electric appliance is parallel with one another accumulator is connected to through button, the circuits DC/DC；
In use, start self-test by lower button, relay obtain it is electric so that relay controlled terminal is closed, mutual inductor
It powers to indicator light after relay controlled terminal, optical coupling isolation circuit；If breaking down, mutual inductor will be unable to obtain electric current letter
Number, thereby indicate that lamp can not be lighted, to know that there is currently failures.
In addition：It should be noted that above-mentioned specific implementation mode is only a prioritization scheme of this patent, the skill of this field
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
