Abstract
The invention discloses an online temperature measuring system of a high-voltage switch cabinet of a transformer substation. The online temperature measuring system comprises multiple signal collecting units. The signal output ends of the signal collecting units are connected with the signal input end of a data collecting unit through an RS232 bus. The signal output end of the data collecting unit performs converging and then is connected with the signal input end of a data monitoring and managing unit through an RS485 bus. The signal output end of the data monitoring and managing unit is connected with the signal input end of a comprehensive automatic system of the transformer substation through the RS485 bus. According to the online temperature measuring system, a temperature state of equipment can be monitored in a real time mode, stoppage caused by overheat can be predicted at an early stage and when the stoppage occurs, the system can perform alarming. Reliability and safety of operation of the high-voltage switch cabinet are improved so as to prevent accidents of the switch cabinet. The online temperature measuring system of the high-voltage switch cabinet of the transformer substation can be used for monitoring safety of the high-voltage switch cabinet of the transformer substation.
Description
Technical field
The present invention relates to a kind of power test system, particularly a kind of high-tension switch cabinet temp measuring system.
Background technology
High-tension switch cabinet is the important electrical in the power engineering construction, is widely used in the substation project design.Along with the user is more and more higher to the requirement of power supply reliability, accordingly the security and stability of transformer station's inner high voltage switch cubicle equipment operation is also had higher requirement.The first-class electric connection part of disconnector, dynamic/static contact, cable position in the high-tension switch cabinet, the excess Temperature phenomenon usually appears in During Process of Long-term Operation, particularly at the heavier city unattended substation of load, overload operation, temperature rise exceeds standard in the switch cubicle, if can not in time find and process, will directly affect the safe and stable operation of equipment, simultaneously the operation maintenance work of equipment operation life and power supply department all produced considerable influence.Therefore, realize switch cubicle inner contact on-line temperature monitoring, can prevent effectively that the switch cubicle accident from occuring, and impels equipment safety operation and reliable power supply.
Summary of the invention
The purpose of this invention is to provide a kind of transformer station high-tension switch cabinet In-Line Temperature Measure System, improved high-tension switch cabinet reliability of operation and security, thereby prevent the generation of switch cubicle accident.
The object of the present invention is achieved like this: a kind of transformer station high-tension switch cabinet In-Line Temperature Measure System, comprise a plurality of signal gathering unit, the signal output part of described signal gathering unit links to each other with the signal input part of data acquisition unit through the RS232 bus, the signal output part of described data acquisition unit gathers by the signal input part of RS485 bus with the data monitoring administrative unit and links to each other, and the signal output part of described data monitoring administrative unit links to each other with the signal input part of comprehensive automation system of transformer substation through the RS485 bus.
As a further improvement on the present invention, described signal gathering unit comprises several infrared temperature sensors.
As a further improvement on the present invention, be provided with alarm unit in the described comprehensive automation system of transformer substation.
The present invention is by infrared temperature sensor, the infrared measurement of temperature data acquisition unit, infrared measurement of temperature monitoring management unit forms, switch cubicle equipment is in service, internal temperature will inevitably constantly change, the present invention is by installation infrared temperature sensor in high-tension switch cabinet, temperature and the variation of the nodes such as interior each contact of Real-Time Monitoring cabinet, tested temperature value is transformed into the voltage signal that can record and process again, sensor output signal changes thereupon when the measured point temperature changes, compile by the data acquisition unit reception, utilize 232 serial communication modes to send to data monitoring administrative unit and comprehensive automation system of transformer substation, comprehensive automation system of transformer substation also can carry out alarm according to parameter preset.Compared with prior art, beneficial effect of the present invention is: the present invention realizes the Real-Time Monitoring of device temperature state, for carrying out early prediction because crossing thermogenetic fault, when breaking down, system can provide warning, and alerting signal can be uploaded report master-control room person on duty or remote dispatching personnel by the communication technology, simultaneity factor also can accurately be located the heating position, guided maintenance work has improved high-tension switch cabinet reliability of operation and security, thereby has prevented the generation of switch cubicle accident.The present invention can be used in the safety monitoring of transformer station's high-tension switch cabinet.
