Vector Frequency Inverter VFD for Motor 0.75kw~630kw

Vector Frequency Inverter VFD for Motor 0.75kw~630kw

Vector Frequency CZPT VFD for Motor .75kw~630kw
 

1. Purpose

Variable frequency inverter(VFD) is employed in underground mines with explosive gasoline (methane) and coal dust. Major spare partsSuch as IGBT, filter capacitor, management main undertake imported makes to make sure dependable longtime
Operation. This series adopt vector control strategy with ideal motor defense
And good pace adjusting to comprehend comfortable start off and comfortable end of the motor. According to the
Load conditions, it can instantly modify the motor pace and decrease the reactive
Influence of the motor commencing on the grid. In the meantime, by way of peripheral sensor, it can
Comprehend variable dynamic handle to attain the objective of strength conserving. Relevant to
Explosion-proof mine hoists, belt conveyor, scraper conveyor, pump station, fan etc. In the
Underground mines.

two. Characteristics

two.1 Undertake no-speed sensor vector. The output torque can attain one.five moments rated torque at
.5Hz. The greatest torque is two instances of the rated torque.
2.2 Heat pipe cooling ensures the cooling prerequisite of the equipment procedure,
Minimizes the system voice and realizes zero servicing.
2.3 Vast frequency altering (two-16kHz) to satisfy demands of various situations.
two.four CZPTent brake modes according to different masses: DC brake, dynamic brake, comments
Brake
two.5 Xihu (West Lake) Dis.n-CZPT interface adopts intrinsically secure circuits for isolation function so that
It can ensure the equipment protection and hassle-free procedure.
two.six With protective functions of more than-voltage, brief-circuit, more than-load, in excess of-heating, phaseloss
And so on.
2.seven With CZPT RS-485 communication interface.
two.8 Very good electromagnetic compatibility.
