Abstract
The invention discloses a kind of 500kV pot type exchange SF6 chopper method of inspection, including, chopper is connected to voltage be 550KV, frequency be 50Hz and set current value circuit in, the electric parameter of chopper is tested；Being put into by chopper in the environment that surrounding air is less than 40 DEG C, the temperature rise to chopper is tested；Within the time set, making by the current value of chopper under "on" position is 63KA, thus checks the tolerance electric current within the setting time of chopper, and the time that sets is as 2s；Rated peak withstand current is checked, i.e. the current peak of first major loop of the specified KA Rms of enough carryings under inspection breaker closing state, and the current peak of first major loop is not more than 160KA；Making by the electric current of chopper is 63kA, thus detects the short-circuit conditions of chopper.Realize the advantage reducing equipment failure rate.
Description
Technical field
The present invention relates to field of electrical equipment, in particular it relates to a kind of 500kV pot type exchange SF6 chopper method of inspection.
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 a kind of 500kV pot type exchange SF6 chopper method of inspection,
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 500kV pot type exchange SF6 chopper method of inspection, including,
Step 1, chopper is connected to voltage be 550KV, frequency be 50Hz and set current value circuit in, to chopper
Electric parameter test；
Step 2, chopper putting into surrounding air less than in the environment of 40 DEG C, the temperature rise to chopper is tested；
Step 3, set time in, making by the current value of chopper under "on" position is 63KA, thus checks open circuit
The tolerance electric current within the setting time of device, the time that sets is as 2s；
Step 5, Rated peak withstand current are checked, i.e. the specified KA Rms of enough carryings under inspection breaker closing state
The current peak of first major loop, the current peak of first major loop is not more than 160KA；
Step 6, make by the electric current of chopper to be 63kA, thus the short-circuit conditions of chopper is detected.
Preferably, described step 1 sets current value as 4000A or 5000A.
Technical scheme, by testing 500kV pot type exchange SF6 chopper, reduces equipment fault
The purpose of rate.
Detailed description of the invention
A kind of 500kV pot type exchange SF6 chopper method of inspection, including,

Step 3, set time in, making by the current value of chopper under "on" position is 63KA, thus checks open circuit
The tolerance electric current within the setting time of device, the time that sets is as 2s；
Step 5, Rated peak withstand current are checked, i.e. the specified KA Rms of enough carryings under inspection breaker closing state
The current peak of first major loop, the current peak of first major loop is not more than 160KA；
Step 6, make by the electric current of chopper to be 63kA, thus the short-circuit conditions of chopper is detected.
Preferably, described step 1 sets current value as 4000A or 5000A.
Also include detecting between the conjunction timesharing to chopper, between the conjunction timesharing of chopper, be not more than 60ms, preferred
Scheme is not more than 50ms for closing between timesharing.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
