Background technology:
Transformer station direct current system is transformer station secondary system important component part, provides DC power supply for primary equipment operation and secondary automation equipment run.Station is become AC rectification into direct current is to battery charging with directly supply DC load by charging module by direct current system, when stand electricity consumption power failure time, continued to provide direct current by batteries, greatly improve the reliability of various kinds of equipment DC power supply; Also by providing AC power for UPS inversion system, to ensure the continual and steady supply of AC power, can ensure that power transformation station equipment normally runs simultaneously.
Direct current system is usually shielded by battery panel and DC charging and is formed, and primarily of rectification charging modular system, storage battery system, supervisory control system, insulating monitoring unit, exchanges the formation such as output unit, DC output unit.Its core component is rectification charging module, is the heart of direct current system.But easily there is lightning current burnout failure in this module in actual motion, and fault substantially cannot field service, mate suitable standby redundancy or contact producer to change and usually need one day even several days time, this, by directly having influence on whole substation safety stable operation, leaves great hidden danger to safe and reliable power supply.
On the other hand, in transformer station secondary system transformation process, direct current power supply is not lost for making transformer station, old direct current cabinet and DC feeder are not removed by usual elder generation, after new direct current cabinet installs and accesses DC load, remove old screen again, cause old screen to occupy construction space, new and old secondary cable interweaves, for retrofit work is made troubles, have a strong impact on operating efficiency and construction period.
Utility model content:
The purpose of this utility model is to overcome deficiency that above-mentioned prior art exists and provides a kind of structure simple, easy to carry, applied widely, alternative different model rectification charging module, stable DC is provided to export, shorten interruption duration, ensure power supply reliability, the portable emergency DC charging device of improvement cost of increasing work efficiency, reduce.
The purpose of this utility model can be reached by following measure: a kind of portable emergency DC charging device, it comprises casing, it is characterized in that the upper end of casing is provided with voltage monitoring unit, control and protection unit, the front panel of casing is provided with direct current output switch, interchange input switch, direct current master switch, direct current output display lamp, exchanges input display lamp, charged display lamp, 3 rectification charging modules, input wires terminal row, output wiring terminal row is provided with, input cable hole, output cable hole, earth terminal in casing; Rectification charging module connects voltage monitoring unit, control and protection unit, interchange input switch, direct current master switch respectively; Exchange input switch and connect interchange input display lamp, direct current master switch connects charged display lamp, direct current output switch connects direct current output display lamp, exchange input switch and connect input wires terminal row, exchange input cable to penetrate through input cable hole to arrange with input wires terminal and be connected, direct current master switch connects direct current output switch, and direct current output switch connects output wiring terminal row, and DC output cable penetrates through output cable hole to arrange with output wiring terminal and is connected.
The utility model can produce following good effect compared with the prior art: the utility model can solve direct current system timely and effectively because of rectification charging module failure and cause transformer station the problem run of normal table and electrical secondary system cannot to transform old screen and to take up space the construction inconvenience problem brought, and particularly cannot find in the short time and change module and the large area blackout of transformer station's full cut-off that exists.
It has:
1. structure is simple, easy to carry.Whole device is the integrated design, and bottom half has four universal wheels, and inside is provided with input/output terminals row, and be convenient to mobile, wiring is simple.
2. applied widely.For the rectification charging module of different model, can effectively solve various fault.
3. shorten interruption duration, ensure power supply reliability.Can directly by the access of emergent DC charging device after breaking down, need not wait for that producer shows up process.
4. reduce entreprise cost.For in transformer station secondary system improvement project, obviously can shorten construction period, increase work efficiency, reduce improvement cost.
