Description
Technical field
The present invention relates to power domain, in particular it relates to the method for inspection of a kind of 500kV shunt reactor protection device.
Background technology
At present, the scheduled overhaul system that in power system, power equipment uses mostly also exists major defect, as provisional
Maintenance is frequently, maintenance is not enough or maintenance is superfluous, blindly maintenance etc., this make countries in the world every year in terms of maintenance of equipment cost huge
Greatly.And for a long time, China's power system performs periodic inspection system to power equipment, the most planned time cycle is to setting
, thus there is maintenance and excessively and overhaul not enough drawback in standby detection and maintenance.Because of fault at power train unification, often cause
Large-area power failure.And there is the problem that fault rate is higher in existing power equipment.
Summary of the invention
It is an object of the invention to, for the problems referred to above, propose the inspection party of a kind of 500kV shunt reactor protection device
Method, to realize the advantage reducing equipment failure rate.
For achieving the above object, the technical solution used in the present invention is:
A kind of method of inspection of 500kV shunt reactor protection device, including:
Step 1, shunt reactor protection device is placed into temperature being-10 DEG C～+55 DEG C, relative humidity is 5% ~ 95%, air
Pressure is in the experimental enviroment of 80kPa～106kPa；
Step 2, ripple factor to the DC source of protection device measure, and the ripple factor of measurement should be less than equal to 5%；
Step 3, ac circuit to protection device detect, and alternating current is in the range of 0.05～20In；
Step 4, being deteriorated the temperature of protection device measures, and in normal operation circumstances temperature range, temperature is deteriorated and does not surpasses
Cross ± 2.5%.
Preferably, also including, it is 2kV that protection device is connected to alternating voltage, and frequency is the forceful electric power loop circuit of 50Hz
In, last whether 1min detection protection device has the step punctured with flashover.
Preferably, also including, it is 500V that protection device is connected to alternating voltage, and frequency is the weak electrical loop circuit of 50Hz
In, last whether 1min detection protection device has the step punctured with flashover.
Technical scheme has the advantages that
Technical solution of the present invention, it is provided that the method for inspection of a kind of 500kV shunt reactor protection device, to 500kV parallel reactance
Device protection device is tested, thus reduces the purpose of equipment failure rate.
