Introduction
LHQYK oil pump switchboard is the special device for controlling the operation of the oil pump, suitable for the AC electric system, of which the voltage is 1.5kV, 3.6kV and 6kV, and frequency is 50/60 Hz. Its rating of enclosure protection is IP53.
LHQYK oil pump switchboard mainly consists of high voltage load breaking switch (for 1.5kV is isolating switch), high voltage vacuum contactor, high voltage current-limiting fuse, control transformer, current transformer, lightning arrester and so forth main components and auxiliary components, and control intellectually by the oil pump controller with the oil pump recording ammeter. This oil pump switchboard can be operated both manually and automatically, features of long electric lifetime and mechanical lifetime without frequent maintenance for the composite structure; safe and reliable for the inner door insulating the high voltage room and low voltage room with safety interlocking device, apply to IEC298 (1990) standard as the ideal product for the oil pump control device.
