Abstract

The invention discloses a detection device for an energy storage module of a hydraulic mechanism for a circuit breaker, and aims at providing a detection device for an energy storage module of a hydraulic mechanism for a circuit breaker, and accurate and rapid in detection. The detection device for the energy storage module of the hydraulic mechanism for the circuit breaker comprises an oil storage tank, a pressing oil pump, a precise filter, a transparent oil cup, an oil return hose, a normally-closed pressure relief valve, an internal pressure sensor, an external pressure sensor, a pressuredisplay panel, and an energy storage module installation base used for installing the energy storage module, wherein a high-pressure port and a low-pressure port which are correspondingly connected with an inlet and an outlet of the energy storage module separately are formed in the energy storage module installation base; a disc spring used for applying a force onto a piston of the energy storagemodule is arranged on the energy storage module installation base; a liquid inlet port of the pressing oil pump is connected with the oil storage tank, and a liquid outlet port of the pressing oil pump is connected with an inlet of the precise filter; during use, an outlet of the precise filter is connected with the high-pressure port of the energy storage module installation base; and the pressing oil pump is used for pumping hydraulic oil in the oil storage tank into the high-pressure port of the energy storage module installation base through the precise filter.

Description

technical field [0001] The invention relates to the technical field of circuit breaker maintenance equipment, in particular to a detection device for an energy storage module of a hydraulic mechanism of a circuit breaker. Background technique [0002] Hydraulic mechanism circuit breakers are widely used in the power industry. With the continuous increase of voltage level and the increasingly complex application places, higher requirements are put forward for the reliability of the hydraulic mechanism of the circuit breaker, especially in the converter station filter. In the equipment field, the average number of circuit breaker actions is dozens of times a day, and frequent suppression of the circuit breaker hydraulic mechanism occurs from time to time. The routine maintenance method for the frequent pressing of the hydraulic mechanism of the circuit breaker is that when the hydraulic mechanism is frequently pressed, all three energy storage modules on the hydraulic mechanis...
