Technical field
The utility model relates to a kind of fault detector proving installation, especially relates to a kind of closed-loop path full-automatic testing device for fault detector.
Background technology
The current method of inspection for distribution line failure indicator generally has:
1) current source be separated and voltage source.Use the current source of separation and voltage source structure to meet the condition of short trouble/earth fault, indicating member forms local alarm instruction or sends a warning message to monitoring means, and monitoring means sends to main station system warning information again and shows.The benefit of this way is simple, all uses existing resource to build test environment, is applicable to initial stage development.
2) integrated current source and voltage source form proving installation, but control desk is separated with simulation main website.Utilize control desk Long-distance Control proving installation, form electric current, the change in voltage waveform of short trouble/earth fault, indicating member forms local alarm instruction or sends a warning message to monitoring means, and monitoring means sends to main station system warning information again and shows.Compare the first way, this way is integrated with current source and voltage source, and the sequential control exported for electric current, voltage is more unified accurately, better simulates short circuit/earth fault.Shortcoming is that control desk and main station system do not integrate, for fault detector inspection pass through/unsuccessfully need artificial judgment, the requirement of Automated inspection cannot be realized.
By the research to above prior art, be very easy to find prior art and mainly there is following shortcoming:
(1) verification scheme 1) can only be coarse simulation short circuit/earth fault, be not suitable for the inspection to batch fault detector.
(2) relative verification scheme 1), verification scheme 2) carry out larger improvement, but control desk and main station system do not integrate, for fault detector inspection pass through/unsuccessfully need artificial judgment, the requirement of Automated inspection cannot be realized.
