Deng.
Under normal circumstances, there is a plurality of belt conveyor an operation area, all continuous running status, wherein every belt goes out
Existing failure can all influence production, if wherein one belt breaks down can not be found in time, front end belt can be made to continue to transport
OK, solid accumulation is caused, piling up can cause certain influence for a long time on production.
Existing belt feeder is electrically using thermal element and motor protecter, more than can only exceed certain overload in motor
In the case of cut off motor.
Utility model content
Electricity can only be cut off for belt feeder fault alarm in the prior art in the case where motor exceedes certain overload
Motivation is powered, and the deficiency such as delay of response, problem to be solved in the utility model is to provide a kind of willing belt conveyer
Fault alarm.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of belt conveyer fault alarm of the utility model, with current transformer, rectifier filter, voltage ratio compared with
The wiring of device module, relay and alarm, wherein current transformer is connected with the input of rectifier filter, rectifying and wave-filtering
The output of device is connected to the negative input end of voltage comparator module, and the output end of voltage comparator module connects relay coil,
Actuating of relay contact is in the control loop of alarm.
Also there is the time relay, be connected in series in the control loop of acousto-optic buzzer.
Controlling switch is installed additional at acousto-optic buzzer end.
Fault alarm has multiple fault detect passages, and each fault detect passage has rectifier filter, voltage ratio
Compared with device module, relay and alarm, multiple fault detect passage electrical structures are identical, powered using same power supply.
The current transformer uses open type, voltage output type, and its wiring is inserted with the input jack of fault detect passage

2. the utility model can be applied in the alarm and protective relaying device of other electric equipments, low cost, application
Scope is wide.
Brief description of the drawings
Fig. 1 is the utility model electrical schematic diagram；
Fig. 2 is the voltage comparator module principle figure in the utility model.
Specific embodiment
With reference to Figure of description, the present invention is further elaborated.
As shown in figure 1, a kind of belt conveyer fault alarm of the utility model, with current transformer, rectifying and wave-filtering
Device and voltage comparator module and relay, the wherein wiring of current transformer are connected with the input of rectifier filter,
The output of rectifier filter is connected to the negative input end of voltage comparator module, voltage comparator module (schematic diagram such as Fig. 2 institutes
Show) output end connection relay coil, actuating of relay contact located at acousto-optic buzzer control loop in.
The current transformer uses open type, voltage output type, and its wiring is inserted with the input jack of fault detect passage
Tall and straight formula connection, the present embodiment uses general 3.5mm headset plugs.
Current transformer structure includes ferrite and coil in the present invention, and electromagnetic induction principle produces sensing in coil
Voltage, for detection；It is for ease of installing, any changing not being done to original detected electric wiring using open type current transformer
It is dynamic.
Used as current detecting, sampling is installed in (can also be transformed with conventional current transformer) transformer inside to voltage output type
Resistance, it is to avoid transformer open running, the voltage for detecting is through diode rectification, capacitor filtering, accurate adjustable potentiometer point
Pressure go to twin voltage comparator module (the present embodiment using using LM339 integrated packages circuit board) be compared, voltage ratio compared with
Accurate adjustable potentiometer is provided with device module, high and low reference voltage is given respectively, detection motor current exceeds or falls below and sets
Determine scope, once curent change is not in setting range, alarm action sends sound and light alarm or control relay protection action.
To avoid electric current transient fluctuation, install the time relay additional and avoid current fluctuation misoperation, delay time is according to circumstances
It is adjustable.
Alarm uses 12V or 24V direct current supplys, and acousto-optic buzzer is equally powered kind using 12V or 24V.
This alarm can also alarm in orderly shutdown, so to install switch additional at acousto-optic buzzer end, in orderly shutdown
When close acousto-optic buzzer, treat that belt system closes acousto-optic buzzer switch before starting, be allowed in pre-alarm state, Ran Houqi
Dynamic equipment, after belt system starts normally, alarm meeting automatic stop alarm, transformer detection load current, output end is produced
Power voltage supply presses comparator, the cut-off of voltage comparator output end, relay release, and alarm is stopped, only when voltage ratio compared with
Device detects when exceeding or falling below setting value that voltage comparator just starts output, drives the actuating of relay.Belt system is normal
Steady state is in during operation, the electric current that motor is reflected changes within the specific limits, if because reductor, belt system,
Electric part or motor go wrong in itself, can embody the change of electric current, once higher or lower than the current range of setting,
Alarm sends sound and light alarm, points out operating personnel according to circumstances to be processed.
This equipment can apply the alarm and protective relaying device in other electric equipments.
