Description
technical field:
The utility model relates to power transmission and transformation field power equipment, specifically a kind of transformer with status monitoring and fault alarm.
background technology:
The effect of transformer in electric power system is irreplaceable, and its running status will directly have influence on the stability of whole power system operation.In order to improve the power supply reliability of transformer, reduce the rate of breakdown of transformer, need to monitor the various quantity of states of transformer, so that just can Timeliness coverage make relevant treatment at the beginning of the running status of transformer worsens, ensure the operation stability of electric power system to greatest extent.The monitoring the most basic to running state of transformer is exactly oil temperature monitoring, and the change of oil temperature can reflect whether inside transformer breaks down to a certain extent.No matter transformer, when breaking down, is overheated type fault or discharge-type fault, all will causes the cracking of transformer insulated medium to a certain extent, will produce various characteristic gas thereupon.At present, normal employing chromatography analysis Oil Dissolved Gases Concentration in electric power system, and then judge transformer initial failure.But the red, orange, green, blue, yellow (ROGBY) implementation cycle is longer, be unfavorable for that detection develops initial failure rapidly.
utility model content:
The purpose of this utility model is just to provide a kind of novel transformer can monitoring oil temperature change and initial failure.
The utility model is made up of transformer and status monitoring and accident warning device, status monitoring and accident warning device are made up of wafer-type temperature sensor, hydrogen test probe, signal conversion module, data processor, wafer-type temperature sensor is used for the change of Real-Time Monitoring temperature of oil in transformer, and hydrogen test probe is for detecting the content of isolated hydrogen in oil in oil tank of transformer.
The utility model is by being fixed on the float of oil level gauge for transformer by wafer-type temperature sensor, the float of oil level indicator floats on the pasta of transformer oil all the time, ensure that temperature sensor can monitor the oil surface temperature of transformer oil all the time, the signal that wafer-type temperature sensor collects is sent to data processor through signal conversion module and carries out data analysis; By hydrogen test probe is arranged on the case lid of oil tank of transformer, hydrogen content information detected by hydrogen test probe is sent to data processor through signal conversion module, data processor through making the judgement of running state of transformer and the diagnosis of fault to Data Collection and analysis, and sends warning message by mobile communication system to related management personnel.
The utility model has the advantages that: the state parameter run by wafer-type temperature sensor and hydrogen test probe Real-Time Monitoring transformer, and utilize signal conversion module and data processor to collect and each operational factor of process transformer, immediate analysis running state of transformer also provides transformer fault warning function, promotes transformer fault process promptness.
