43035 Wuhan of company of phone of grand of intercontinental of Cheng bright Wuhan

Origin: Pole of uncut jade of Mian Lai white

Summary: It is with system of direct current source of power of GZDW of company of phone of Wuhan intercontinental grand intelligence exemple, introduced intelligence system of direct current source of high frequency switch is safeguarded in of a few common breakdown eliminate, safeguard the job to also have referenced value to system of direct current source of other model intelligence.
Keyword: GZDW system, the system is safeguarded, be defeated by transformer substation

1 overview
In recent years, as the enlarge of electric power electrified wire netting look and urban and rural electrified wire netting are transformed further, system of direct current source of high frequency switch already replaced intelligence to accuse dc to handle power source stage by stage, became various one of main fixture that transport transformer substation. Wuhan intercontinental GZDW intelligence is high frequency system of switch direct current source is to be aimed at power system of high reliability and high electric performance ask and design, systematic collect PWM, soft switch, personal computer controls a technology at an organic whole, rectification module uses heat to all shed a technology backup, automatically, but electrified change, intelligence changes batteries management to be able to prolong battery service life. Systematic monitoring labour accuses machine can realize close end and long-range monitoring through RS232, RS485 or MODEM interface, have perfect 4 Yao function. Feed unit uses disjunction capacity the breaker of special model carapace with tall, minor volume, have a label marked, operation is convenient wait for a characteristic. This system basically is used at of all kinds power plant, transformer substation, communication, electric railway and building to change 2 loop, breaker cent closes distribution room brake and emergency lighting use phone.

Composition of 2 typical systems reachs working principle
GZDW intelligence is high frequency system of switch direct current source accuses machine monitoring unit, deputy monitoring unit, attune to press appearance of check of module unit, batteries make one's rounds, insulation by unit of module of commutate of high frequency switch, labour unit of input of censorial unit, feed unit, communication and batteries ark a few parts. Because the actual condition of various places and each user are laden equipment difference is bigger, the composition of system of power direct current source is chosen by user oneself more. Graph 1 it is GZDW is used at transformer substation of 10kV ～ 110kV to reach general medium or small the composition of system of power plant direct current source.
