Description
Technical field
A kind of high- and low-voltage circuit dead electricity warning device is the utility model is related to, belongs to Mine Switch cabinet technical field.
Background technology
The colliery transformer station of high dual power supply is required for coal peace, due to lacking warning device, causes operations staff
The change of circuit operation conditions when can not learn inlet wire dead electricity or incoming call, especially siding, usually not on-load, dead electricity when
Wait, if the not on-site tour of operations staff, it is difficult to which the very first time finds power down mode at circuit, the electricity when stopped, stop
How long.Therefore it is a kind of safe and reliable auxiliary equipment of substation operation management（Or device）.
At present, the product that circuit charged state can be reflected in commercially available prod is usually a electrification display, typically all
On switch cubicle, but use and have very much limitation, operations staff only could see circuit in the observation of front eye
Charged state, minute can not leave display, influence operating efficiency.
Utility model content
To solve technical problem existing for prior art, the utility model provides one kind and uses audio alert, simple real
With, high- and low-voltage circuit dead electricity warning device safe and reliable, easy for installation.
To achieve the above object, technical scheme is high- and low-voltage circuit dead electricity warning device used by the utility model, bag
Include to be arranged on switch cubicle and be used to detecting the voltage sensor of voltage, the voltage sensor by signal shaping amplification module with
The signal input part of light-coupled isolation drive module is connected, signal output part and the relay control of the light-coupled isolation drive module
The signal input part of circuit processed is connected, and the signal output part of the control relay circuit is connected with voice alarm module,
The live loudspeaker of installation at the scene are connected with the voice alarm module, the voice alarm module also passes through audio driven mould
Block is connected with the night shift room loudspeaker installed in night shift room, and SR is additionally provided with the control relay circuit.
Preferably, the signal shaping amplification module includes rectification circuit and scale operation amplifying circuit.
Preferably, the incoming call dead electricity record for recording the event that occurs is additionally provided with the control relay circuit to look into
Ask module.
Compared with prior art, the utility model has following technique effect：The utility model has simple and practical, safety
Reliably, the characteristics of easy for installation；It is not required to do existing system too many change, as long as the alternating current by existing voltage sensor
Induced signal accesses the present apparatus, and device is formed required stabilization signal, recycled by the screening to signal, amplification
The stabilization signal starts voice broadcasting system, so as to inform operations staff on duty rapidly；Present apparatus band signal reset function, signal
Involution must be arrived in front of device and operated, and otherwise device alarm can not automatically terminate, therefore promote operations staff to be carried out to opening and closing room
Involution operates and further confirms that system operation situation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are more clearly understood, with
Lower combination drawings and Examples, the utility model is further elaborated.It is it should be appreciated that described herein specific real
Example is applied only to explain the utility model, is not used to limit the utility model.
As shown in figure 1, high- and low-voltage circuit dead electricity warning device, including be arranged on and be used for the voltage for detecting voltage on switch cubicle
Sensor 1, voltage sensor 1 are connected by signal shaping amplification module 2 with the signal input part of light-coupled isolation drive module 3
Connect, wherein, signal shaping amplification module 2 includes rectification circuit and scale operation amplifying circuit；The letter of light-coupled isolation drive module 3
Number output end is connected with the signal input part of control relay circuit 4, the signal output part and voice of control relay circuit 4
Alarm module 5 is connected, and the live loudspeaker 6 of installation at the scene are connected with voice alarm module 5, and voice alarm module 5 is also logical
Cross audio driver module 7 with the night shift room loudspeaker 8 installed in night shift room to be connected, be additionally provided with control relay circuit 4 multiple
Position button 9, the incoming call dead electricity record queries module 10 for recording the event that occurs is additionally provided with control relay circuit 4.
Because the voltage of voltage sensor output is exchanges between 15V ~ 110V in the utility model, and the energy provided
Amount is very low, it is therefore desirable to carries out shaping amplification to the signal of collection.By rectification circuit and scale operation amplifying circuit, by signal
Become stable 5V switch DC signals, then active switching signal is become by passive switch by optocoupler drive module and believed
Number, i.e., indicated electriferous state has electricity to be changed into relay tip conjunction state, otherwise is open state.Pass through control relay circuit
Start voice alarm module program, quote the running status of circuit exactly（For example quote：Please note Gong Jia village circuit dead electricity or
Please note Gong Jia village circuit incoming call）, remotely（Night shift room）Report need to increase the amplification of one-level audio, make voice broadcast sound more big vast
It is bright, during voice broadcast on the spot and remotely（Night shift room）Broadcast simultaneously.Operations staff can know siding quickly by the prompting
The situation of road dead electricity, and get in touch and restore electricity with upper level transformer station in time；It can judge that transformer station's whole station has a power failure quickly
To be caused as line side failure or as caused by this station failure, make operations staff restore electricity or take in a short time it is other
Effective measures.Logout and enquiry module are started by control relay circuit, by the event occurred such as any bar circuit, hair
Raw what change (incoming call or dead electricity situation), the change when occurred are recorded for inquiring about at any time one by one.
In addition, control relay circuit also girdle tests and reset function, test function can verifying attachment operation at any time
Reliability；When an event occurs, device is unable to automatic resetting signal, and voice broadcast state only can be just made after artificial involution
Stop.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., all should be wrapped in the utility model model
In enclosing.
