Abstract

PURPOSE:To back up a constant speed power supply with an accelerating power supply by dividing a power supply into the accelerating an constant speed ones when a number of motors with large inertia moment operate parallelly. CONSTITUTION:An accelerating power supply VV operates up to the minimum frequency and a switch LV1 makes contact. This premits m units of the motors M11 to M1m which are assigned to the first group to start and to be accelerated up to the maximum frequency by the program control of accelerating power supply VV. After acceleration is completed, the switch LV1 opens and is connected to the constant speed power supply CV which non-load-operates at the maximum frequency by making contact by inputting a switch C1. Then, the accelerating power supply VV decreases up to the minimum status at nonload and the acceleration of all machines is completed by sequentially performing the switching acceleration to constant speed up to the second to the n-th groups. When the capacity of the constant speed and acceleration power supplies CV and VV is equalized, back up constant speed operation is performed by accelerating the power supply VV at the failure of the contact speed power supply CV.
