【文章內(nèi)容簡(jiǎn)介】 xt passes and programs to the charged barbed wire with electric power and designs the technique principle of the aspect the standard concerning electric voltage grade, power supply credibility, power supply ability and charged barbed wire safe power supply 3 requests etc. some problems that should notice in the charged barbed wire safety。And have already aimed at sex39。s elaborating request to the concrete design principle opposite charged barbed wire safe power supply of the 220 kV transformer substation and 110kV transformer substation. How to promise power supply credibility 1)Satisfy charged barbed wire power supply safe power supply work satisfies the request of power supply standard that all satisfies Nl, city area center high burden density important customer in the district satisfy the standard of transformer over a southern city power supply credibility rate index sign programming target is %. 2)Press to go together with charged barbed wire burden to transfer ability in the city satisfy following request: ① The transformer substation loses any once enter line or one set lord transformer but lower power supply ability, win press to go together with charged barbed wire to have to transfer burden to ensure the ability of power supply. ② When a female line of transformer substation stops a luck because of putting, winning to press to go together with charged barbed wire should have the ability that transfer all burden. ③ When the 10 kv goes together with electric wire road any check to fix or breaks down, going together with the charged barbed wire should have non check of transfer to fix, non breakdown segment ability for non check fixs, The non breakdown segment carries to the power is off time only for go together with to give or get an electric shock an equipments to pour a Zha operation for time. 3)Ask to satisfy a following principle while allowing the capacity of the power outage and the target of the instauration power supply while going together with charged barbed wire breakdown to make the customer the power is off: ① The customer of two back track power supplies , after losing a back track, should be unlimited to give or get an electric shock. ② The customer of three back track power supplies , after losing a back track, should be unlimited to give or get an electric shock, again after losing a back track, should satisfy power supply capacity 5070% is used an electricity. ③ When all of a back track or much
