Embodiment
Please refer to Fig. 1, is the system for the monitoring substation transformer of the present invention.This system comprises: monitoring host computer 1 and monitoring extension set 2.Wherein monitoring extension set 2 can have one or more (only schematically having drawn one in Fig. 1), and every monitoring extension set 2 is arranged near a station power distribution transformer, is used for this station power distribution transformer is monitored.
Particularly, monitoring extension set 2 can be connected to the leading-out terminal of monitored substation transformer, is used for the performance parameter of substation transformer is detected, and these performance parameters comprise following any one or more: voltage parameter, current parameters and temperature parameter.Can understand the current duty of substation transformer by these performance parameters of analyzing substation transformer, and then the abnormal work state of substation transformer is found on ground can be anxious the time, and taked corresponding eliminating measure.
Particularly, after monitoring extension set 2 detects the performance parameter of monitored distribution depressor, send to monitoring host computer 1 by the mobile network, for example by SMSC(Short Message Service Center, SMS service center) performance parameter is sent to monitoring host computer 1.At power domain, when carrying out data transmission between general device, what generally adopt is the mode the transmission of data of power carrier, and power carrier has the shortcomings such as power frequency serious interference, signal attenuation is serious, electrical noise is large, thus make the data accuracy of transmission and real-time all relatively poor.Yet the utility model but adopts the mobile network (for example: SMSC) carry out the transmission of data, because substation transformer generally is arranged in position close to the residential block, therefore the general mobile communication signal in these positions is relatively good, therefore adopt the mobile network to carry out the transmission of data, can improve real-time and the accuracy of data transmission.
The below is introduced the 26S Proteasome Structure and Function of monitoring extension set 2 of the present utility model particularly.
Please refer to Fig. 2, is the structural representation of the embodiment of monitoring extension set 2 of the present utility model.The monitoring extension set 2 of Fig. 2 comprises: power module 20, the acquisition module 21 that is linked in sequence, signal processor 22, central processing unit 23 and GSM(Global System of Mobile communication, global mobile communication) module 24.
Wherein acquisition module 21, are used for gathering the performance parameter of monitored substation transformer.Described in aforementioned, the performance parameter of substation transformer can comprise following any one or give closes: voltage parameter, current parameters and temperature parameter.Wherein, voltage parameter can be gathered by voltage transformer (VT), and current parameters can be gathered by current transformer, and temperature parameter can be gathered by temperature sensor.
