High voltage explosion-proof inverter installation

As the application of high power inverters in the MW level is typical for railway traction industry, the failure of module can cause fractures sprayed. The extreme consequences may involve main busbar short-circuit, damage the gate control circuitry and others.

lso note the following points to prevent an accidental failure, inj y, electric shock, etc.:(1) Transportation and installationCAUTIONSince the inverter s non-explosion-proof, always install it in a non-hazardous pla .When carrying products, use correct lifting gear to prevent jury.Do not stack the inverter boxes higher than the number

One of failures is module explosion during the operation in the filed or even at test bench. The high power module explosion can cause direct damages and huge influences to surrounding systems or even cause safety problems depending on its application scenario [1-3]. 1. Introduction

a power failure, provide a magnetic contactor in the inverter's primary circuit and also make up a sequence, which will not switch on the start signal.If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as th

The inverter uses plastic parts. Handle it gently to protect it from damage. Also, hold the u it with even strength and do not apply too much strength to the front cover alone.Install the inverter i a place where it is immune to vibration. (5.9 m/s2 or less) Also note the cart, press, etc.

duce.5. When Pr. 162 = "1", the output frequency before an instantaneous power failure is stored and output a t e time of restart. If the power of the inverter control circuit is lost, the frequency before an i stantaneous power failure cannot be stored and the inverter will start at 0Hz.6. The SU
