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
The present invention relates to a kind of power equipment state monitoring devices, particularly relate to a kind of transformer station's oiling equipment oil impregnate speed monitoring system utilizing piezoelectric sensor and single chip computer measurement technology.
Background technology
At present, in generating plant or substation, many equipment can produce a large amount of heats in normal operation, such as, so equipment has cooling device, a transformer usually, water or oil can be used to cool.In addition, transformer station also has some oiling equipment and so on, if these equipment generation leakage of oils or cooling device leak, if because some situation must allow equipment remain in operation, can not be had a power failure process immediately, with regard to needing, Real-Time Monitoring being carried out to the leakage scenarios of equipment, with antiseep conditions worsen, causing serious consequence owing to carrying out timely and effectively processing.
In the case, adopt the most direct method to be exactly manual inspection, arrange fixing staff to reconnoitre detection in real time.But the time of monitoring continues very long sometimes, iff only carrying out manual inspection by staff, a development trend effectively can not following the tracks of seepage in real time, needs the manpower of at substantial simultaneously.In today that human cost rises steadily, pure use manual inspection is unpractical, so realize intelligentized detection and the latest data detected can be transferred to equipment manager being only the most effective mode.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, a kind of transformer station oiling equipment oil impregnate speed monitoring system is provided, this transformer station's oiling equipment oil impregnate speed monitoring system gathers the oil droplet landing information of leakage of oil point by Piezo droplet measurement sensor, single-chip microcomputer is entered via the collection of analog quantity AD interface, in time dripping speed higher than a certain setting value, the mobile phone of note to setting is sent by gsm module, substation operation managerial personnel are helped to understand leakage of oil point leakage scenarios in time, take effective measures in time to judge, thus remove the puzzlement that substation operation personnel need prolonged and repeated tour from.
The technical solution adopted for the present invention to solve the technical problems is: a kind of transformer station oiling equipment oil impregnate speed monitoring system, comprise the Piezo droplet measurement sensor that transformer station's oiling equipment leakage oil droplet region is detected, be connected with Piezo droplet measurement sensor and receive the single-chip microcomputer of the output signal of Piezo droplet measurement sensor, the LCD MODULE be connected separately with single-chip microcomputer, buzzing alarm module, short message transceiving module, short message transceiving module is connected with LCD MODULE, short message transceiving module is connected with relay, relay is connected with to start measures switch, described Piezo droplet measurement sensor and single-chip microcomputer are all connected with by the constant-current supply of lithium battery power supply, single-chip microcomputer is also connected with gsm module, and the data collected are sent on the mobile phone of equipment manager by gsm module, to carry out real-time follow-up to seepage trend.
Further, described Piezo droplet tester is provided with simulation AD interface and gathers oil droplet landing information.
Further, described single-chip microcomputer is also connected with key-press module, and breakthrough rate is sent to equipment manager by gsm module with note form manually to input object phone number by key-press module.
Further, described LCD MODULE is LCDs.
Further, described buzzing alarm module is made up of hummer and alarm lamp.
Further, the drop that described Piezo droplet measurement sensor is 3 millimeters, 10 centimetres drops for diameter exports 3-5V analog quantity.
