UPS already became application to solve one of the mainest measures of power character issue in the factory, but also have a few otherer can be worth to consider for the method of the choice. A kind of when limited company of electron of power peaceful gram makes new-style fast voltage regulator (AVC) the market that entering this to solve means to occupy dominant by the tradition in great quantities. Vernon Pryde is right fast voltage regulator (AVC) make one introduction.

20 years ago, UPS main goal is the application with the most sensitive issue of character of those pairs of power. These are considered as “ at that time trade the application of ” , banking of reduce of its target market, data, IT and all of commercial computer science department. And now, if who is building a modernization that has certain automation rate,not active consideration uses a large number of UPS when the factory, that is inconceivable. This is the part of the effect that power quality and power supply safeguard should have and UPS. The author ever had visited a semiconductor plant in the Asia, the spot owns the UPS mothball system with more than 75 made of baked clay million.

Put the issue that be in:
“ voltage mutation or light already were decided to be the most general interference of influence model manufactory. ” this fact already was reported by numerous and independent institute and make a file, this is incontestable.

Reason and consequence:
The commonnest breakdown cause can induce as follows:
Thunder: Basically often can appear in place of be struck by lightning overvoltage, but interesting is the commonnest consequence that causes it is single-phase voltage light however.
Storm: Wind plays the fragment to transmit electricity line to be able to cause odd opposite ground and alternate with trouble. Typical transmission network operating sequence is to carry out coincide brake for many times to try cleared breakdown, those who form fast sequence for many times voltage light incident. Origin: Pole of uncut jade of Mian Lai white?
Traffic accident: Car develops a way, the transmit electricity line of run down place.
Ice and snow: Ice and snow of the accumulation on electrical wiring basically can cause single-phase flash over and trouble.
Cabled yarn breakdown: Contact by the accident when mining, maintain undesirable bring about with insulation fault.
Still have a lot of common causes that cause trouble, if flyer is bumped, the animal has climbed insulator to touch conductor, fire causes jump arc, saline mist is polluted, cabled yarn and transformer breakdown are waited a moment.
The type of breakdown
Already affirmatory, the probability of single-phase breakdown in the breakdown that happen is occupied 80% , two-phase is to ground breakdown 10% , two-phase breakdown is 5% , three-phase breakdown also is 5% .
Because the breakdown of great majority happens in the place of the factory that is far from you, consequently notable is, the possibility of complete power failure is very little. The breakdown that happens on ark of the breakdown that happens inside your factory only or your a certain feed just causes complete power failure likely. And all and other event can increase voltage light number only.
