Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the better embodiment of the utility model box-type substation comprises high powered device, transformer, low-voltage distribution equipment, supervising device 2 and locking device 3, high powered device, transformer and low-voltage distribution equipment are electrically connected to successively, described high powered device is arranged in described hyperbaric chamber 12, described transformer is arranged in described transformation chamber 13, described low-voltage distribution equipment is arranged in described low-pressure chamber 14, in order to facilitate unloading and transportation, at the top of casing 1, be provided with four suspension ring 11.Because the emphasis that high powered device and low-voltage distribution equipment etc. and the utility model will be set forth is irrelevant, therefore do not repeat them here.
Described locking device 3 is arranged on the safety net door off-position place in transformation chamber 13, and described locking device 3 is electrically connected to and is set to electrical interlock with the high-voltage switch gear 31 in described high powered device.
Described supervising device 2 comprises three current transformers 24, Temperature Humidity Sensor 23, analog to digital converter 22, controller 21, warning device 26 and wireless communication module 25, described three current transformers 24 are separately positioned on three-phase low-voltage output line, described Temperature Humidity Sensor 23 is arranged in transformation chamber 13, described three current transformers 24 and Temperature Humidity Sensor 23 are electrically connected to described analog to digital converter 22 respectively, and described analog to digital converter 22, described warning device 26 and described wireless communication module 25 are all electrically connected to described controller 21.Temperature Humidity Sensor 23 and three current transformers 24 are all transferred to analog to digital converter 22 by the signal detecting, analog to digital converter 22 converts the signal of reception to digital signal, and sending digital signal to wireless communication module 25, wireless communication module 25 sends the digital signal receiving to Surveillance center again.When controller 21 calculates warning message, controller 21 is controlled warning device 26 and is reported to the police.Wherein, described warning device 26 is buzzer, and described locking device 3 is travel switch.
Please refer to Fig. 4, described wireless communication module 25 comprises: the central processing unit 251 being connected with controller 21, for resolving the modulator-demodulator 252 receiving, order and obtain operational order; The described modulator-demodulator 252 being connected with central processing unit 251, sets up for the operational order, the operation wireless communication protocol that receive from central processing unit 251 modulation and demodulation that communication link connects, receives the baseband signal of self-controller 21 and completes baseband signal; The described memory being connected with modulator-demodulator 252, for storing relevant information; And the described antenna 254 being connected with modulator-demodulator 252, for receiving and dispatching radiofrequency signal.
When the safety net door in transformation chamber 13 is closed completely, locking device 3 disconnects, and the high-voltage switch gear 31 in hyperbaric chamber 12 just can conducting; When safety net door isolating and protecting grid, do not close completely, locking device 3 is closed, and the high-voltage switch gear 31 in hyperbaric chamber 12 disconnects, and can not complete power transmission.So, guaranteed that operating personnel open safety net hyperbaric chamber 12 power-off behind the door, thereby effectively avoided security incident.
