Title: Multi-vane fan
Inventor: SANO KIYOSHI
IPC: F04D29/66
Filed: 1987-12-24
Abstract: PURPOSE:To obtain an effect of reducing blade pitch sound by disposing respective blades in such a manner that the center line of each blade has a designated angle to the axia of a rotary shaft of a fan and the center lines of adjacent blades have a designated angle to each other in fan. CONSTITUTION:When a multi-vane fan 2 is driven, air passes through a heat exchanger 3 to be sucked in the direction of an arrow (a) and is accelerated while it passes through the multi-vane fan 2 to be blown out in the direction of an arrow (b). At this time, through blades 8 of the multi-vane fan 2 gradually change in flow velocity and pressure with rotation of the multi-vane fan due to nonuniformity of flow velocity distribution of air and mutual intervention of air in a stabilizer 4, fitting pitch angles of the blades 8 are continuously changed in the direction of the axis of a rotary shaft of the multi-vane fan 2, whereby frequency of blade pitch sound is dispersed to be decreased. Further, the blades are disposed in such a manner that shifting in ditting pitch angle of every section of the multi-vane fan 2 differs so as to increase the effect.

Abstract: PURPOSE: To obtain an accurate faulty section decision unit having wide applicability by discriminating use, nonuse and reverse polarity of each electric amount data based on the using state of a setting means for a decision region and performing a fault detecting operation for each decision region. CONSTITUTION: Current data is read in from all current transformers CT1, CT2, ..., CT7 in decision regions Z1, Z2, Z3 and then the CT state of each decision region Z1, Z2, Z3, being set by a setting unit 5, is read out. Since the use, nonuse, and reverse polarity of a CT input are set as '1', '0' and '-1', respectively, only a current data required for each decision region Z1, Z2 or Z3 is incorporated in the current differential operation by combining the set values with each current data. A fault detection operating unit 6 makes a decision of fault detection by deciding whether the operating amount is higher than an operating level. If it is higher than the operating level, a fault detection signal of a concerned decision region is outputted.
