Abstract

The invention discloses a substation oil-filling equipment oil leakage rate monitoring system. A piezoelectric droplet measuring sensor collects oil drop dropping information when an oil drop at an oil leakage point passes through a sensor setting region; the oil drop dropping information is collected by an analog quantity AD interface and is input to a single-chip microcomputer; a lithium battery is adopted to supply power; and when the dropping speed is higher than a certain set value, leakage rate is calculated after circuit processing and single-chip microcomputer processing, and the leakage rate is sent to a set mobile phone through a GSM module in the form of a short message, thereby facilitating to carry out real-time tracking on the leakage trend, helping operation and management personnel of a substation to know the oil leak information of the oil leakage point in time so as to make decisions and take effective measures in time, and preventing the trouble of long-term repeated patrol of the operation and management personnel of the substation.

Description

technical field [0001] The invention relates to a state monitoring device for electric power equipment, in particular to an oil seepage rate monitoring system for substation oil injection equipment using piezoelectric sensors and single-chip microcomputer measurement technology. Background technique [0002] At present, in power plants or substations, a lot of equipment will generate a lot of heat under normal operation, so the equipment usually has a cooling device, such as a transformer, which uses water or oil for cooling. In addition, the substation also has some oil injection equipment and the like. If oil leakage occurs in these equipment or water leakage occurs in the cooling device, if the equipment must continue to operate due to certain circumstances, and the power cannot be cut off immediately, it is necessary to check the leakage of the equipment. Real-time monitoring of the leakage situation to prevent the leakage situation from deteriorating, causing serious co...
