LOPS fun MV Bus Overvoltage Idaabobo

Ohun elo idinku kekere foliteji akero LOPS jẹ asopọ taara ni afiwe si ọkọ akero naa, ni lilo awọn imọ-ẹrọ bii awọn olutona iyara, awọn resistors ti ko ni agbara giga, awọn interceptors tente oke foliteji, ati idinku ikọlu. O jẹ iṣiro imọ-jinlẹ ati apẹrẹ daradara. LOPS ni kikun nlo awọn abuda ampere volt ti o dara julọ, agbara igbona nla, ati iyara idahun iyara ti awọn interceptors overvoltage, awọn alatako ti kii ṣe lainidi, ati ohun elo ipakokoro. Ni gbogbogbo, ṣeto iye iṣe ti LOPS ni awọn akoko 1.2 foliteji alakoso eto (aṣeṣe ni awọn ọran pataki) le ṣaṣeyọri awọn abajade to dara lakoko iṣẹ.

LOPS ti sopọ taara ni afiwe si ọpa ọkọ akero, ni lilo awọn imọ-ẹrọ bii awọn olutona iyara, awọn alatako alaiṣe agbara giga, awọn interceptors tente oke foliteji, ati idinku ikọlu. O jẹ iṣiro imọ-jinlẹ ati apẹrẹ daradara. LOPS isanpada fun aipe bi SPD, ni idapo overvoltage Idaabobo, ati resistance capacitance gbigba, patapata lohun awọn isoro ti overvoltage lori alabọde foliteji busbar akọkọ.
