Abstract
The invention relates to a testing method for delayed output time of a signal control terminal of an intelligent electric energy meter. The testing method utilizes a double-path oscillograph to record two paths of voltage waveforms during electrifying time of the intelligent electric energy meter; then an output time difference of the two paths of voltage waveforms is calculated and the time difference is the delayed output time at an electrifying moment of the signal control terminal of the intelligent electric energy meter; the two paths of the voltage waveforms are two paths of voltage waveforms of a self voltage loop of the intelligent electric energy meter and a voltage loop of a signal control terminal of a metering circuit breaker; and the intelligent electric energy meter is a local cost controlling electric energy meter of an external relay. The testing method disclosed by the invention has the beneficial effects of effectively detecting the quality of the local cost controlling electric energy meter of the external relay, and solving a secondary tripping fault (caused by powering on after powering off) of a shunt trip circuit breaker.

Technical field
The present invention relates to a kind of intelligent electric energy meter signal controlling terminal and postpone output time method of testing, be applicable to the Series Intelligent expense control electric energy meters (external relay) such as DDZY188C-Z, DDZY47C-Z, the DDZY33C-Z moment breaker signal control terminal that powers on and postpone the test of output time.
Background technology
Current domestic local charge control electric energy meter (external relay), it is that high pressure of signal controlling terminal output or the low-voltage signal of counting by table controlled isolating switch (switch) folding condition that user's isolating switch (switch) is controlled.Domestic user's isolating switch (switch) adopts shunted exciter tripping type relay mostly, and in the time having a power failure, shunted exciter tripping isolating switch still can keep "on" position, and the delay trip time after shunted exciter tripping isolating switch powers on is often about 1 second.If after local charge control electric meter signal control terminal powers on the time of output be greater than delay trip time of shunted exciter tripping relay, will cause power failure to send a telegram here again to user after shunted exciter tripping circuit breaker trip, cause user again to have a power failure.Cause inconvenience to the user on the one hand, on the other hand because user does not know trip reason, often dial power supply service hotline, caused great burden to Utilities Electric Co..
Therefore, signal output time after how testing local charge control electric energy meter and powering on, becomes the key index in local charge control electric energy meter (external relay) test.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of intelligent electric energy meter signal controlling terminal and postpones output time method of testing.
