摘要： PURPOSE:To make an automatic ranging possible, by a method wherein a scanner, a variable amplification factor amplifier and a variable reference value comparator which are all controlled by a computer are provided. CONSTITUTION:Outputs of vibration detectors 1 are applied to a computer 12 through amplifiers 7 in which amplification factors are set, the said amplification factors being selected on the basis of a command given by the computer 12, and through an A/D converter 11 in which the outputs applied are converted into digital quantities. The computer 12 operates the input based upon the amplification factor, and compares the operated result with the predetermined abnormal vibration level or with the defective level of detecting system. When the abnormality is detected, the computer displays an abnormal channel, and gives an alarm. A variable reference value comparator 10 compares the set reference value with the vibration level, and applies an signal when there is a difference. The computer repeats to increase or decrease the amplification factor until no output is applied from the comparator 10. Then, the vibration level is A/D converted based upon the amplification factor at the time so as to be able to read the vibration level which does not overflow. Besides, the fault conditions in the detecting system can be recognized by the value shown.

摘要： PURPOSE:To eliminate a calculation error of fatigue life consumption of a rotary shaft system, by directly measuring the twist vibration in an optional position of the rotary shaft system to be estimated, and comparing said measured value with an estimated value. CONSTITUTION:Twist vibration is measured at plural fixed positions of a rotary shaft 4 system, and by use of the measured torsion vibration, twist vibration in other optional position of the rotary shaft system is estimated, and from the estimated twist vibration, fatigue life consumption in an optional position is derived. Subsequently, twist vibration generated in one position at least in the optional position is measured, and is compared with twist vibration in an estimated position. Also, when an absolute value of a difference of these 2 values has exceeded a prescribed value, no operation of fatigue life consumption is executed, by which a calculation error of the fatigue life consumption is eliminated.

摘要： PURPOSE:To make it possible to collect gas easily even when the quantity of gas in oil is small, and also to perform operation continuously and rapidly, by providing a gas extractor, gas discharger and infolammable gas detector. CONSTITUTION:Sample oil in transformer 1 is led to oil-collecting metering container 13 by being suched by bellows type gas discharger 19 and supplied from container 13 to waste oil container 14 by overflowing. Next, solenoid valve 15 is opened to supply the sample oil to bubbling tank 15 and then solenoid valve 16 is closed. With solenoid valve 17 opened, air flows into the oil and then flows into bellows type gas discahrger 19 together with dissolved gas in the oil. When the inside of discharger 19 is kept under the atmospheric pressure, solenoid valve 20 is closed and solenoid valve 24 is opened to send gas to be detected to inflammable gas detector 25 for the measurement. Thus, the operation can be performed continuously and even when the quantity of gas in oil is small, the measurement can be taken with accuracy.

摘要： PURPOSE:To efficiently monitor twist vibration, by deriving the displacement of 1 freedom degree vibration system corresponding to each natural frequency, and multiplying and adding a natural mode value of an optional point of each mode, so that twist vibration in an optional position can be calculated. CONSTITUTION:Twist vibration Y (xj, t) in plural positions xj of a rotary shaft system (provided that, j=1-l), and external force F (sk, t) working on the rotary shaft system at a fixed position sk (provided that, k=1-m) are measured by deriving in advance natural frequency fi (i=1-n) extending to n-th degree of the rotary shaft system, a natural mode form gi(x), equivalent mass Mi of 1 freedom degree vibration system having the natural frequency fi, an equivalent damping coefficient Ci, and an equivalent spring constant Ki. When i-th degree equivalent external force Fi (t) of the external force F (sk, t) is operated by the expression 1, and displacement of i-th degree 1 freedom degree vibration system is set to hi(t), displacement of i-th degree is estimated in accordance with the expression 2, and twist vibration Y (x, t) in an optional position (x) of the rotary shaft system is derived by the expression 3.

摘要： PURPOSE:To eliminate a sudden change of data from a vibration level during normal operation, by a method wherein vibration information during stoppage is replaced by a vibration level value just before the stoppage. CONSTITUTION:A computer system 5 is applied with a vibration detecting output from a detector 2 through an amplifier 3, and at the same time applied with a signal which shows the condition of the operation of rotary device from an auxiliary contact 7 interlocked to a main switch 6. The computer stores vibration levels applied from the detector 2, as they are, in a memory within the computer for the time when the auxiliary contact 7 is closed, namely for the time when the rotary device 1 is operating, T6, T8 and T10. When the operation is stopped, the contact 7 is opened, and the computer stores a vibration value sampled at the end of the operation in the memory within the computer. The diagnoistic operation of the abnormality of the vibration level and detecting system is performed during the time when the contact 7 is closed, and is not performed when the rotary device is stopped.
