Description
Technical field
The utility model relates to the calibrating of current transformer, especially relates to a kind of device of low-voltage current mutual inductor outward appearance for metering that detects.
Background technology
The current transformer of applying in electrical network is that the large equal current proportion in a circuit is reduced into the required little electric current in double measurement loop, mainly realizes the electrical isolation at high-low pressure two ends and the function that equal proportion is measured.Current transformer for metering is for one of main measurement instrument of electric energy trade settlement, belongs to state compulsion calibrating standard.Each current transformer for metering all needs could normal use after qualified by calibrating and periodic calibration first.It is wherein one that outward appearance in the various detections of current transformer is detected, current known technology is all non-robotization, all by manually operating, that is: whether correct by manually checking the outward appearance sign of current transformer to be checked, not only efficiency is extremely low, cost of labor is high, and artificial memory's fatigue can not guarantee 100% detection correctness, even under this high duplication wiring, energising working condition, Artificial Consciousness is tired out, brings artificial danger.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of detection simple in structure, lightweight, flexibility and reliability to measure the device by low-voltage current mutual inductor outward appearance in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of device measuring by low-voltage current mutual inductor outward appearance that detects, it is characterized in that, this device comprises frame, drives cylinder, upper lower push-rod, guide rail and optical camera, described driving cylinder is arranged on frame lower, described guide rail is arranged on central rack, and described optical camera is arranged on frame top; Described upper lower push-rod is arranged on and drives on cylinder.
Described guide rail matches with the pipeline of low-voltage current mutual inductor automatic calibration streamline with metering.
Described optical camera comprises top camera, top light source, side camera and side light source.
Described upper lower push-rod top is provided with the jaw that clamps current transformer and driven rotation.
Optical camera is no less than 500,000 pixels.
Wherein, when the utility model device is used, metering is transported to the pallet that mutual inductor is housed on the guide rail of the utility model device with low-voltage current mutual inductor automatic calibration streamline, after pallet gear stops, by upper lower push-rod and driving cylinder, realize the operations such as mutual inductor height control and mutual inductor rotation; Top camera and light source complete the inspection of mutual inductor top nameplate and secondary wiring terminals; Side camera and light source complete mutual inductor side, physical dimension and primary connection terminal (multiple circle type) and check.
What for mutual inductor nameplate, surface, one/secondary wiring terminals and physical dimension, occur is abnormal, and system will be recorded as defective, and return by the middle line of return, no longer carry out next step calibrating.
Compared with prior art, the utlity model has following advantage:
1. outward appearance has detected the inspection of the contents such as shell, assembly quality, component surface processing, connection terminal, nameplate model, current ratio, secondary load, the precision information of mutual inductor, polarity mark, secondary polarity mark, comprehensively reliable.
2. realize to mutual inductor the detection and localization on pallet, and according to testing result to exceeding the scope of once rectifying a deviation, the mutual inductor that exceeds secondary correction scope rejects; Data are accurate.
3. outward appearance detects the flow direction of defective mutual inductor: with the underproof mutual inductor of dielectric voltage withstand, through middle conveyer line, pass labeling station, full automatic working back.
