quick phase
2.DJW-WB,SJW-WB series of series of single-phase three-phase micro-computer superpower AVR,it gathers advaned combinated roll compensation,no-touch of wsitch,and micro-motor controlhaving special function such as high efficiency,energysaving,quick adjustment,auto-balance of three phase,no machanical breakdown and carbon brush fret.Especially,the avantages of timedelay,over-voltage and under-voltage protection absorbs more and more customers.
3.The principles of hardware and software for the protection of high-voltage electromotor in quick break, inverse-time-limit and single-phase grounding are discussed with a presentation on the eatablishment of the mathematics model.
5.It adopts the relative triggering mode to realise the phase-shifting and quick adjustment of the control-angle α, and makes sure that the maximum time of losing control is less than 3.3ms.
6.DJW-WB、SJW-WB Series single and three phase &large-power auto compensated Voltage regulator,Incorporating advanced technology of group winding compensation and mon-contact suitch and micro-computer controling AC regulation, with functions of high effeciancy quick regulating ou-to-balance of three phases no mechanical no mechanical broken down and wear of carbon brush and time delay over and low load warning and protection.
7.As a result,we adopted the ANNPR-CTRL strategy in cell growth phase to increase cells concentration as quick as possible. After cells concentration reaching a relatively high level,a transient period of 5～6h was adopted by simultaneously feeding a mixture of glucose and methanol by ANNPR-CTRL strategy so that the Pichia pastoris cell could gradually adapt the environment using methanol as the inducer.
