2.The current configuration state for main transformer of south electric network and several problems met in practical project were introduced. Some of special problems of main transformer protection were analyzed and discussed.
5.This paper applies Electronic Power Transformer(EPT) into the distribution network to optimize and control the voltage and reactive power synthetically.
6.New~type distribution transformer supervisory control system based on network communication with general packet radio service
8.This paper compares the performances of three communication networ ks of integrative automatic transformer substation, points out that the integrativ e automatic transformer substation base on CAN (Controller Area Network) and Eth ernet technique is the inevitable trend of the development of the field of trans former automation.
9.By analyzing systematically the production principle of the common mode noise which is the major factor affecting quality of the switch mode power supply,the decision is reached that the common mode noise is walking through coupling earth capacitance transmitting output, and then a practicable measure of restraining noise is put forward:screens are added between major switch tube and radiation, between transformer primaries and transformer script,or FRD can be selected with R C absorb network.
10.Distribution transformer remote monitoring terminal based on DSP TMS320LF 2407A and wireless module GR 47 is designed,which takes DSP as controller and GPRS(General Packet Radio Service)wireless network and Internet as communication channel to transmit teledata for remote monitoring of distribution network operational parameters and states.
11.In accordance with the driving characteristics of AC driving locomotive,the working status of its traction transformer is analysed.The questions that should be considered in the traction transformer design of AC driving locomotive are mentioned.These questions are the large short-circuit impedance of traction winding,higher harmonic current,over-excitation and DC magnetization caused by large variation of the network voltage,etc.Some disposal methods are given.
12.The technical analyses and economic comparisons for the generator with GCB and also the necessity for the generator with GCB are discussed when the generator is connected to a network and the startup/standby transformer is supplied from another.
13.There are many methods applied to study the faults inside the power transformers, such as the neural network (NN) method, the fuzzy set theory method, the expert system (ES) method, the application, of synthetical artificial intelligence (AI) technique, the transformer fault on-line monitoring technique, etc.
14.The sprayer is usually connected with water supply network, control value, detection alarm unit, etc. to form an automatic water spray system(such as sprinkler fire-extinguishing system) for saving electrical equipment, fighting burning flammable liquid, etc. it is widely used for fire control and cooling protection for such equipment/places as power plant* generating machinery, large size transformer, liquefied petrolatum tank, factory, shopping mall, hotel, warehouse, storied building and so on.
