Abstract

PURPOSE:To make it possible to detect the abnormality of a delicate hydraulic system accurately and to save the labor of maintenance and security on the switching operation. CONSTITUTION:As a cause of the variation of the hydraulic pressure, there is the influence of the temperature other than an oil leak, and that is resulting from the variation of the pressure of the gas 6 enclosed in an accumulator 5 owing to the variation of the temperature. Consequently, even though the operational time of a pump unit 3 is measured, it cannot be decided accurately whether the measured time is owing to the practical oil leak or to the influence of the temperature. Theretore, on the operation of the pump unit 3 with no switching operation, only the number of of operations is measured, and the measurement of the operation time to detect the reduction of the injection amount of oil from the pump unit 3 is carried out only in the switching operation time. In such a way, even to the abnormarity of the delicate hydraulic system, an accurate detection can be made, and the labor saving to the maintenance and the security of the switching operation of a breaker can be realized.
