Description
Technical field
This utility model relates to a kind of GIS transformer station sulfur hexafluoride gas pressure of monitoring to be changed and the device of warning, belongs to substation field detection technique field.
Background technology
For the sulfur hexafluoride gas of GIS device Pressure gauge on the spot in transformer station, checked meter by manual patrol and be monitored, thus the atmospheric pressure trends in artificial judgment GIS device has been a kind of generally acknowledged discovering device gas leakage, has ensured that equipment medium has the effective means of certain dielectric strength.
At present, power industry requires periodically the sulfur hexafluoride gas pressure in GIS power equipment is patrolled and examined and checked meter, patrol and examine and check meter to generally rely on and manually carry out, and the data obtained of checking meter carries out manual analysis judgement, this work expends a large amount of manpowers and time, and anthropic factor is relatively big, sulfur hexafluoride pressure value could not be compensated to standard figures when 20 DEG C, be unfavorable for the judgement of gas pressure change trend；Although part transformer station achieves robot and patrols and examines, but subject to conditions, it is impossible to full station is patrolled and examined, and degree of accuracy is the most not high enough, does not carry out the analysis of sulfur hexafluoride force value Long-term change trend.
Summary of the invention
The purpose of this utility model is, check meter for GIS power equipment manual inspection in transformer station, the change of manual analysis sulfur hexafluoride gas pressure trend brings many troubles, the utility model proposes a kind of GIS transformer station sulfur hexafluoride gas pressure of monitoring and changes and the device of warning.
The technical solution of the utility model is, the sulfur hexafluoride gas pressure change of a kind of GIS of monitoring transformer station and the device reported to the police include GIS device, Gas sampling joint and valve, sulfur hexafluoride gas pressure transducer, environment temperature sensor, signal processor, industrial computer and warning system.
The input port of Gas sampling joint and valve connects GIS device, the gas outlet of Gas sampling joint and valve connects sulfur hexafluoride gas pressure transducer, the output port of sulfur hexafluoride gas pressure transducer and environment temperature sensor connects signal processor, by cable, signal processor is connected to industrial computer again be monitored, industrial computer output is connected to warning system, realizes monitoring and warning function.
Gas pressure value in described GIS device can represent sulfur hexafluoride gas pressure trend, it is achieved reports to the police.
nullOperation principle of the present utility model is，When monitoring the device work of GIS transformer station sulfur hexafluoride gas pressure trend and warning，By the sulfur hexafluoride gas of GIS device in transformer station，By special valve and joint，Sulfur hexafluoride gas pressure transducer is accessed with copper pipe，The pressure signal that scene obtains is transferred to signal processor by pressure transducer，The temperature signal that scene obtains is transferred to signal processor by environment temperature sensor，Signal processor is further according to force value、Ambient temperature value is converted into the analog current signal of 4-20mA，After analogue signal accesses industrial computer，Known special-purpose software is utilized to convert analog signals into on-the-spot actual sulfur hexafluoride force value、Temperature value，This device can be adjusted as required by sample frequency，Store online numerical value，And by the ambient temperature gathered, sulfur hexafluoride gas force value is compensated to standard figures when 20 DEG C，Industrial computer can carry out the history curve drafting of force value according to storage data，Finally this signal is compared with warning or lock-in threshold，If it exceeds threshold value，Then warning system will be activated，Thus achieve GIS air chamber gas pressure change Trend judgement and the intellectuality of warning system，Whether the gas in discovering device exists leakage in time.
The beneficial effects of the utility model are, this utility model is for monitoring GIS transformer station sulfur hexafluoride gas pressure trend and the device of warning, the online numerical value of sulfur hexafluoride gas pressure can be stored, industrial computer can carry out the history curve drafting of force value according to storage data, and realize reporting to the police and the function of locking, change the way that current manual inspection is checked meter, manually carried out data analysis judgement, substantially reduce workload, and gas pressure change trend has been carried out visual feedback, it is ensured that the safe and reliable operation of equipment.
This utility model is suitable for use with sulfur hexafluoride gas as insulation and the GIS electrical equipment of arc-extinguishing medium.
