Embodiment
As depicted in figs. 1 and 2, a kind of power switch cabinet electrified display interlock apparatus, this power switch cabinet is provided with front cabinet door and rear cabinet door, front cabinet door is provided with charged display device 1, rear cabinet door is provided with five anti-lock 2, described five anti-lock 2 are provided with electronic unlock device 22, described electronic unlock device 22 accesses five anti-network systems, described charged display device 1 realizes communicating to connect by order wire 14 with band electrical induction device 13, whether described band electrical induction device 13 detects high-tension cable 11 by air dielectric 12 charged and result is transferred to charged display device 1, described charged display device 1 shows result, after receiving the uncharged information of high-tension cable, described electronic unlock device anti-lockly to unlock five.
As shown in Figure 1, described band electrical induction device is electrified sensor, it is the field coupled principle utilized between high-voltage electric field and electrified sensor, outside safe distance, carry out induction type (contactless) measure, it detects the change of high-tension cable by air dielectric, thus judges that whether high-tension cable is charged.
Charged display device 1 is arranged on indoor electric equipment, whether intuitively demonstrates electrical equipment with working voltage, carry out safety instruction by display.When equipment is with working voltage, display display window flashes, and warning people high-tension apparatus is charged, then without instruction during nothing electricity.
Described charged display device 1 is provided with five preventing key output interfaces, described five are anti-lockly provided with five preventing key sockets, described charged display device is by five preventing key output interface output information to five preventing keys 15, and described five preventing keys insert five preventing key sockets and input the whether charged information of high-tension cable to electronic unlock device.When equipment live, charged display device 1 realizes anti-error function to five anti-lock output forced blocking signals, and when equipment is without electricity, charged display device removes five anti-lock block signals, can carry out the operation of equipment.
As shown in Figure 2, described five anti-lock 2 comprise lock pin 21, and the doorframe of switch cubicle rear cabinet door is provided with locked groove, lock pin first end is provided with tapered end 212, and lock pin second end is connected with spring 23, when being in blocking, under the action of the spring, described tapered end is sticked in locked groove.Described lock pin is provided with the first gap slot 213, described electronic unlock device comprises control circuit, solenoid 22, described control circuit receives five preventing key input information and connect solenoidal power supply in the not charged situation of high-tension cable, solenoidal iron core energising is shunk, and deviate from from the first gap slot, thus remove the locking to lock pin.Described lock pin is provided with strip through-hole 211, and through guiding screw pole 215 in described strip through-hole, described guiding screw pole guides lock pin to slide.
As shown in Figure 3 and Figure 4, also be provided with trip lever 24, separate lock dog 25, the first end of trip lever 24 is provided with waist type cross-section 242, and the second end of trip lever 24 is provided with raised line 241, this raised line 241 coordinates with the draw-in groove on five preventing keys, makes five preventing keys that trip lever 24 can be driven to rotate.
