DC power supply in use needs to charge by charger at present, charger when work technical indicators such as steady wave system number, the precision of voltage regulation, precision of steady current can be along with the aging of the prolongation of service time, electronic devices and components variation, therefore these technical indicators of online remote monitoring charger are very important, output voltage, electric current also necessarily require to stablize, unsettled voltage, electric current can influence the life-span of DC power supply, cause apparatus overheat even burn.
At present the subject matter that exists is that the DC power supply charging voltage that causes of intrinsic program setting of charger and DC power supply number mismatch is too high, causes to overcharge.As certain transforming plant DC power supply intrinsic 102, even charging voltage is but fixedly adjusted and is 245V, causes that easily DC power supply overcharges.Charger module failure phenomenon appears in part transformer station.The phase-controlled power of part transformer station may cause the DC power supply damage or influence the DC power supply life-span, and cause overheated and other supplementary load loss to operating equipment owing to self reason (ripple coefficient is bigger, and the precision of voltage regulation and precision of steady current are not enough).Find through overtesting as us, also there is the excessive problem of pulsating current in certain transformer station, if the property checked discharge test is done by such transformer station, may have influence on the DC power supply life-span, if do not do the property checked discharge, can't check DC power source capacity, and bring negative effect also may for the safe operation of DC power supply and direct current system.
And early stage microcomputer insulating monitoring inspection device is owing to be subjected to the influence of the direct current system mode of connection, the insulating monitoring device can't play the effect of expection, basically still rest on the bus warning stage, for concrete branch road, most transformer stations still need to adopt the mode that the branch road outage searches to seek earth point.
For guaranteeing the safe operation of DC power supply, need a large amount of staff to take turns at keeping watch, waste time and energy, inefficiency, and be difficult to find timely fault.
