Abstract
The invention discloses an operating temperature monitoring and early warning system for a distribution network transformer. The system comprises a communication server, a temperature measurement terminal, a digital intelligent temperature sensor and the distribution network transformer, wherein the digital intelligent temperature sensor is connected with the distribution network transformer; the output end of the digital intelligent temperature sensor is connected with the input end of the temperature measurement terminal; and the temperature measurement terminal performs data transmission with the communication server through a general packet radio service (GPRS) network. The system has the beneficial effects that the digital intelligent temperature sensor is arranged on the distribution network transformer to measure the oil temperature of the transformer and upload data to the communication server through the temperature measurement terminal to finish the automatic real-time measurement of the oil temperature of the transformer, and monitoring and early warning for the oil temperature of the transformer can be realized through communication service software in the communication server, so that the system is convenient, reliable and labor-saving, accidents can be effectively avoided, the equipment state overhauling and management level of the transformer can be improved, and the transformer can be more safely and reliably operated.
Description
Technical field
The present invention relates to a kind of distribution transformer running temperature monitor and early warning system, be applicable to distribution transformer temperature detection technical field.
Background technology
In cities and towns and rural area, the distribution transformer is to use the most general electric power facility, and its consumption is big, distribution is wide, for resident's daily life, enterprises and institutions' production work provide electric power endlessly.But lack effective Supervision Measures for a long time, cause fault to happen occasionally, cause the property loss of electric power supply department, influence people's life and work.The key of distribution transformer safe operation is that its working temperature is unsuitable too high, otherwise can lead to fire even explosion accident.The difficult point that the running temperature of distribution transformer is monitored is too wide because of its distribution, and the manual inspection input expends too big.Transformer is of a great variety in addition, and it is different to install and use condition, also brings a lot of difficulties to manual inspection.
Summary of the invention
The technical matters that the present invention will solve provides a kind of distribution transformer running temperature monitor and early warning system, can realize the real-time monitoring and the early warning of transformer temperature, saves manpower, can effectively avoid accident to take place; Improve transformer equipment repair based on condition of component management level, make the operation of transformer more safe and reliable.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is: a kind of distribution transformer running temperature monitor and early warning system comprises the communication server, thermometric terminal, digital intelligent temperature sensor and distribution transformer; Said digital intelligent temperature sensor is connected with the distribution transformer; The output terminal of digital intelligent temperature sensor is connected with the input end at thermometric terminal; The said thermometric terminal and the communication server are through GPRS net transmission data.
The present invention also comprises database server, and said database server is connected with the communication server is two-way.
The model of said digital intelligent temperature sensor is DS18B20, and the model at said thermometric terminal is GTO-TMI.
The embedded GPRS module in above-mentioned thermometric terminal, and the transformer temperature data uploading that will gather in real time through the GPRS net gives the communication server, data transmission adopts standard MODBUS agreement, conveniently is connected with distribution automation system; Installation communication service software in the communication server is responsible for the temperature data of each leading portion transformer of collection in real time, carry out alarm analysis and handle, and responsible be deposited into all data centralizations is made long preservation in the database server.The related work personnel can carry out data query to transformer ruuning situation, receive monitoring such as alarm, displays temperature curve, printout form and management by the internal control network.
Temperature probe is installed in the said digital intelligent temperature sensor, temperature detection, A/D conversion, CPU processing and network interface is integrated, directly export interference-free digital temperature data.Above-mentioned temperature probe has two kinds to install and use form: a kind of is plug-in type, adopts the standard couple mounting structure, can directly insert transformer-cabinet inside, accurately measures the oil temperature; Another kind is an absorption type, for the transformer of not reserving the fuel temperature measurement probe insertion, can near heating position this absorption type temperature probe be installed in the transformer tank external, guarantees accurately to measure the oil temperature.
Beneficial effect of the present invention is following: through digital intelligent temperature sensor measurement temperature of oil in transformer is installed on the distribution transformer; And upload the data to the communication server through the thermometric terminal; Realize the automatic real-time measurement of temperature of oil in transformer, can realize the monitoring and the early warning of temperature of oil in transformer through the communication service software in the communication server, convenient and reliable; Save manpower; Can effectively avoid accident to take place, improve transformer equipment repair based on condition of component management level, make the operation of transformer more safe and reliable.
