Abstract
The invention discloses a 35kV outdoor vacuum circuit breaker detecting method. The 35kV outdoor vacuum circuit breaker detecting method comprises the steps that a circuit breaker is connected with a circuit having a voltage of 40.5KV, a frequency of 50Hz, and a set current value, and the electrical parameters of the circuit breaker are detected; the circuit breaker is disposed in an environment having an air, the ambient temperature of which is less than 40 DEG C, and the temperature rising of the circuit breaker is detected; in the set time, the current value of the circuit breaker is 31.5KA in a closed state, and therefore the withstand current of the circuit breaker in the set time is detected, and the set time is 4s; the rated peak value withstand current is detected, and the current peak value of the first major loop of the rated short-time withstand current, which can be withstood by the circuit breaker in the closed state, is detected, and the current peak value of the first major loop is not greater than 80KA; the current across the circuit breaker is 31.5kA, and therefore the short circuit condition of the circuit breaker is detected. The advantage of reducing device failure rate is realized.
Description
Technical field
The present invention relates to field of electrical equipment, in particular it relates to a kind of 35kV outdoor vacuum circuit breaker method of inspection.
Background technology
At present, the scheduled overhaul system that in power system, power equipment uses mostly also exists major defect, and as frequent in provisional maintenance, maintenance deficiency or maintenance surplus, blindly maintenance etc., this makes countries in the world costly in terms of maintenance of equipment every year.And for a long time, China's power system performs periodic inspection system to power equipment, to equipment Inspection and maintenance, thus there is the drawback that maintenance is excessively not enough with maintenance in the most planned time cycle.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 35kV outdoor vacuum circuit breaker 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 35kV outdoor vacuum circuit breaker method of inspection, including,
Step 1, chopper is connected to voltage be 40.5KV, frequency be 50Hz and set current value circuit in, the electric parameter of chopper is tested；
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 31.5KA, thus checks the tolerance electric current within the setting time of chopper, and the time that sets is as 4s；
Step 5, Rated peak withstand current are 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 80KA；
Step 6, make by the electric current of chopper to be 31.5kA, thus the short-circuit conditions of chopper is detected.
Preferably, described step 1 sets current value as 1600A, 2000A or 2500A.Technical scheme has the advantages that
Technical scheme, by testing 35kV outdoor vacuum circuit breaker, reduces the purpose of equipment failure rate.
