At present after high-voltage switch cabinet, the design of door latch apparatus comprises switch machine locking device and five anti-devices etc. independently, for loop grid, there is potential safety hazard in above-mentioned closedown mode, when high-tension switch cabinet is charged, may cause and open by mistake cabinet back door, cause personnel's electric shock accidents.
Summary of the invention
The utility model proposes a kind of high-tension switch cabinet locking device, to effectively prevent from opening by mistake cabinet back door.
To achieve these goals, the utility model proposes a kind of high-tension switch cabinet locking device, described device comprises power module, and the universal logic module being connected with described power module respectively, high pressure identification module, electromagnetic lock, charged demonstration indicator light, sound and light alarm module, communication module and transducer group, wherein said transducer group comprises first sensor and the second transducer; Described universal logic module also respectively with described high pressure identification module, electromagnetic lock, charged demonstration indicator light, sound and light alarm module, communication module and the second transducer are connected; Described high pressure identification module is also connected with described first sensor.
Preferably, described the second transducer adopts torque sensor.
The beneficial effect of this scheme of the present utility model is effectively to prevent from opening by mistake cabinet back door, and the state of high-tension switch cabinet can be uploaded to monitoring system of electric substation by communication module, realizes monitoring in real time.
Accompanying drawing explanation
Fig. 1 shows the related high-tension switch cabinet locking device principle schematic of the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As shown in Figure 1, the related high-tension switch cabinet locking device of the utility model comprises power module 10, universal logic module 20, high pressure identification module 30, electromagnetic lock 40, charged demonstration indicator light 50, sound and light alarm module 60, communication module 70 and transducer group 80, wherein said transducer group 80 comprises first sensor 801 and the second transducer 802.
Described power module 10 respectively with universal logic module 20, high pressure identification module 30, electromagnetic lock 40, charged demonstration indicator light 50, sound and light alarm module 60, communication module 70 and transducer group 80 are connected, and are its power supply.Described universal logic module 20 respectively with high pressure identification module 30, electromagnetic lock 40, charged demonstration indicator light 50, sound and light alarm module 60, communication module 70 and the second transducer 802 are connected.Described high pressure identification module 30 is also connected with first sensor 801.
The related high-tension switch cabinet locking device of the utility model is mainly used in the cabinet back door of locking high-tension switch cabinet, prevents from opening by mistake cabinet back door electric shock accidents occurs.
Voltage in described first sensor 801 real-time detection high-tension switch cabinets, and this magnitude of voltage is sent in described high pressure identification module 30.
In described high pressure identification module 30, be provided with the supply voltage threshold value of electromagnetic lock 40, the magnitude of voltage from first sensor 801 and above-mentioned threshold value compared, and comparative result is sent to universal logic module 20.
The signal that described universal logic module 20 receives from high pressure identification module 30, and make following control action:
(1), when the voltage in comparative result is high-tension switch cabinet is greater than described threshold value, 20 pairs of electromagnetic locks of described universal logic module 40 send the first control signal, make its locking; And charged demonstration indicator light 50 is sent to the second control signal, it is lighted; And communication module 70 is sent to the first status signal, and showing under current state, high-tension switch cabinet locking device is in blocking, and this communication module 70 can further be sent to monitoring system of electric substation by this first status signal, to realize monitoring in real time;
(2), when the voltage in comparative result is high-tension switch cabinet is less than described threshold value, 20 pairs of electromagnetic locks of described universal logic module 40 send the 3rd control signal, make its release; And charged demonstration indicator light 50 is sent to the 4th control signal, it is extinguished; And communication module 70 is sent to the second status signal, and showing under current state, high-tension switch cabinet locking device is in released state, and this communication module 70 can further be sent to monitoring system of electric substation by this second status signal, to realize monitoring in real time.
When the voltage in high-tension switch cabinet is greater than described threshold value, the signal that universal logic module 20 receives from the second transducer 802, described the second transducer 802 can be torque sensor.When having, people is premeditated to be opened or opens by mistake while opening high-voltage switch cabinet back door, and the second transducer 802 can detect the physical change that cabinet back door occurs, and its can convert this physical change to the signal of telecommunication and be sent to described universal logic module 20.Described universal logic module 20, after receiving this signal of telecommunication, can send the 5th control signal to sound and light alarm module 60, makes it send sound and light alarm; And communication module 70 is sent to third state signal, show that high-tension switch cabinet locking device is when locking, because of the alarm condition that has people's misoperation to form, this communication module 70 can further be sent to monitoring system of electric substation by this third state signal, to realize monitoring in real time.
The related high-tension switch cabinet locking device of the utility model can safety, the cabinet back door of effective locking high-tension switch cabinet, prevent the electric shock accidents that the misoperation due to personnel causes, and the state of high-tension switch cabinet can be uploaded to monitoring system of electric substation, realize monitoring in real time.
