Description
Technical field
The present invention relates to a kind of alarm device for middle-placed switch cabinet.
Background technology
10KV and above switch cubicle are intermediate switchgear cabinet at present, due to wheelbarrow switch maintenance in intermediate switchgear cabinet
Time, handcart need to be pulled out cabinet；The valve of now wheelbarrow switch moving contact turnover cabinet will be accordingly turned off (being provided with charged in cabinet
Static contact).But when pressing the kinematic link opening valve such as staff, valve will be opened, and charged switch is quiet by mistake by mistake
Contact will exposed out, personnel will be occurred to get an electric shock casualty accident when staff touches charged static contact by mistake.So be
Prevent valve from being opened by staff by mistake, cause the generation of human casualty accident, it is necessary to develop and a set of prevent valve from opening by mistake
Alarm device.
CN104165659A patent of invention discloses one " middle-placed switch cabinet Centralized Monitoring alarm device ", senses including gate inhibition
Device, brows, door lock, cabinet, Smoke Sensor, humiture transducer, monitoring unit, switch, display screen, power on light, UP
Key, down key, smog Sensing interface, entrance guard sensor interface, humiture transducer interface and power input interface；Monitoring unit
On be provided with switch, display screen, power on light, UP key, Dwon key, humiture transducer interface, smog Sensing interface, door
Prohibiting sensor interface, Smoke Sensor is arranged on position, rack convex top；Entrance guard sensor is arranged on cabinet each front/rear door upper left
Angle；Humiture transducer is arranged on rack concave crown part, and monitoring unit is arranged on middle-placed switch cabinet tip position, on cabinet front/rear door all
Equipped with door lock." entrance guard sensor " of this technical scheme is arranged on the upper left corner of each front/rear door, and after door lock opens by mistake, gate inhibition senses
Device can send a signal to monitoring unit, the computer in monitoring unit up-delivering signal to machine room, Computer display alarm letter immediately
Breath is to director on duty.Although this technical scheme sends a warning message to operator on duty after " door lock " opens by mistake, but still deposits
In problems with:
1. though information transmission is fast, but settlement mechanism is delayed: after operator on duty receives warning information, puts in needing to go to
Manual-lock is carried out before cabinet.During this period, if other staff touch in the case of unwitting and exposed have electrical contact by mistake,
Still there is electric shock risk；
2. structure is complicated, and use cost is high, and is easily damaged: need to arrange entrance guard sensor, background client terminal, communication network
Networks etc., structure is the most complicated, and use cost is too high；It addition, monitoring unit needs to arrange multicomponent, in reality uses easily
Damage.
This device is directed to the gate control system that middle-placed switch cabinet cabinet front/rear door is installed, but it can not solve cabinet wheelbarrow switch
Pass in and out the function valve of the inside (middle-placed switch cabinet Qianmen just can see after opening) preventing maloperation of charged bus storehouse valve.
At present the most apparently, it is still desirable to develop a set of easy to use, alert eye-catching, low the preventing of simple in construction, use cost
The alarm device that middle-placed switch cabinet valve opens by mistake.
Summary of the invention
The invention provides a kind of easy to use, alert eye-catching, simple in construction, use cost low prevent middle-placed switch cabinet valve
The alarm device opened by mistake.
The technical scheme realizing above-mentioned purpose is as follows: middle-placed switch cabinet valve alarm device, including cabinet, handcart, valve, company
Bar, described connecting rod is connected with described valve, it is characterised in that: also include an alarm terminal, one group of alarm switch and for even
Connect the warning circuit of alarm terminal and alarm switch.
Further, described alarm terminal includes Flash cell, calling unit；Described Flash cell system is arranged on described work
The LED of outer side of door；Described calling unit system is arranged on the speech player outside described valve.
Further, " Keep Clear-High Voltage " four The Scarlet Letters that described Flash cell system is combined into by straw hat lamp bead；Described voice is broadcast
The content putting device broadcasting is " Keep Clear-High Voltage " four words.
Further, described alarm switch is respectively arranged on described connecting rod handcart turnover stroke microswitch and
It is arranged on the link rotatable stroke microswitch below described connecting rod.
When handcart leaves run location, " handcart turnover stroke microswitch " Guan Bi, " Alarm Unit " obtains electric, " alarm
Circuit " scanning " link rotatable stroke microswitch " position.If staff opens by mistake valve, " warning circuit " discovery " connecting rod
Rotational travel microswitch " Guan Bi, " warning circuit " connection " alarm terminal ", The Scarlet Letter flashes, and alerts speech play；Until valve
Closing, " link rotatable stroke microswitch " disconnects, " warning circuit " closedown " alarm terminal ".
When handcart is by overhauling or time testing position is pushed into run location, " handcart turnover stroke microswitch " is opened, and disconnects
Installation's power source, even if now valve is opened, wheelbarrow switch carries out into cabinet, and phonetic alarm is the most no longer reported to the police.
Compared with prior art, the present invention possesses following significant progress: easy to use, alert eye-catching, simple in construction, make
Use low cost.

Detailed description of the invention
With reference to the middle-placed switch cabinet valve alarm device shown in Fig. 1～2, including cabinet 1, valve 2, connecting rod 3, described connecting rod 3 with
Described valve 2 is connected, and also includes the alarm terminal being made up of Flash cell 6 and calling unit 7, is opened by handcart turnover stroke fine motion
Close 4 and the alarm switch of link rotatable stroke microswitch 5 composition and for connecting the alarm of alarm terminal and alarm switch
Circuit.
Described Flash cell 6 is that to be arranged on " Keep Clear-High Voltage " four that be combined into by straw hat lamp bead outside described valve 2 red
Word；Described calling unit 7 is to be arranged on the speech player that can play " Keep Clear-High Voltage " four words outside described valve 2.
Described handcart turnover stroke microswitch 4 is arranged on connecting rod 3；Described link rotatable stroke microswitch 5 is arranged
Below connecting rod 3.
With reference to Fig. 3～5, when handcart leaves run location, " handcart turnover stroke microswitch " Guan Bi；Valve is closed,
" link rotatable stroke microswitch " disconnects.Now warning circuit obtains electric, MCU(U3) start working, scan " link rotatable stroke
Microswitch " position.
If staff opens by mistake valve, " link rotatable stroke microswitch " closes, and the light emitting diode of optocoupler U1 is led
Logical, U1 the 4th foot output low level.After MCU detects this signal, control speech chip U5 and export voice signal, put through power amplifier U6
After great, driving loudspeaker to send audio alert prompting " Keep Clear-High Voltage, forbid opening ", MCU controls LED flicker simultaneously.This voice is anti-
Replay is put, until valve is closed, " link rotatable stroke microswitch " disconnects, and MCU controls speech chip U5 and stops playing, simultaneously
MCU extinguishes LED.
When handcart is by overhauling or time testing position is pushed into run location, " handcart turnover stroke microswitch " is opened, and disconnects
Installation's power source, even if now valve is opened, wheelbarrow switch carries out into cabinet, and phonetic alarm is the most no longer reported to the police.
Compared with prior art, the present invention possesses following significant progress: easy to use, alert eye-catching, simple in construction, make
Use low cost.
Above example is the explanation of the detailed description of the invention to the present invention, rather than limitation of the present invention, relevant technology
The technical staff in field is without departing from the spirit and scope of the present invention, it is also possible to makes various conversion and change and obtains
To the technical scheme of corresponding equivalent, the technical scheme of the most all equivalents all should be included into the patent protection model of the present invention
Enclose.
