Small current grounded line gating and tuning method based on arc suppression coil access control short time heteromorphic signal

The invention discloses a small current grounded line gating and tuning method based on an arc suppression coil access control short time heteromorphic signal. The method comprises the following steps: (1) carrying out extraction and grounded line gating on the arc suppression coil access control short time heteromorphic signal; (2) preferentially tuning the faulted gated grounded line along with the arc suppression coil; and (3) putting the arc suppression coil into operation, compensating for capacitance current of a fault point, and extinguishing an electric arc. The method disclosed by the invention has the advantages that in the step (1), the arc suppression coil is not accessed into a power system, and the grounded line is gated and a tuning device is used for rapidly acquiring and analyzing voltage and current signals of the power system when the power system has a single phase grounded fault, so that the grounded faulted line is accurately selected; and in the step (2), the rated zero sequence capacitance current ICn0N of each line of the system is calculated in advance and stored in a designated database, the total rated zero sequence capacitance current ICsigma0N of the line is calculated by utilizing the data obtained by acquiring and analyzing after a fault and combining the line gating result and the data in the database, so as to take ICsigma0N and a reasonable tuning coefficient as a basis for calculating a tuning work point of the arc suppression coil, and then the arc suppression coil is correctly tuned.

Method for measuring sub-surface affected layer depth and morphology of optical material

The invention relates to the technical field of optical precise measurement, especially a method for measuring the sub-surface affected layer depth and morphology of an optical material. The method comprises the steps: firstly enabling a sample to be clamped on a clamping mechanism in uniform motion; controlling the clamping mechanism to enable the HF acid solution to immerse in the sample till the sample is completely merged in the solution; quickly extracting the sample from the solution, and employing a probe-type contourgraph to measure a corroded profile, thereby obtaining the profile curves in the longitudinal depth direction of a crack and the vertical movement direction of the sample; calculating the height difference between a critical point or a pole point and a starting point or the height difference between the critical point projected on an original surface or a pole point on the original surface and a starting point on the original surface through the critical point or the pole point and the starting point recorded in a measurement process, wherein the critical point or the pole point are the points where data obtained on the curves starts to level off, and the height difference is the sub-surface affected layer depth D of the sample; and employing an optical microscope to observe the three-dimensional shape of a corroded plane. The method provided by the invention is simple, quick and accurate, can measure the sub-surface affected layer depth and the three-dimensional shape, is high in testing precision, is low in cost, is high in visualization, and exerts low requirements on testing equipment.

Method for selective metal film layer removal using carbon dioxide jet spray

A method for the selective removal of the metal film layer (14) accumulated upon a photoresist layer (10) during processing of substrates using a stream of carbon dioxide spray (20) without disturbing conductor portions is provided. A constant stream (20) of high pressure CO2 snow is applied to the metal film layer thereby rapidly cooling the metal layer on top of said resist layer causing it to shrink rapidly, and to debond, and peel from the photoresist layer underneath. The temperature of the substrate is raised and maintained at significantly higher than room temperature. Continuing the application of the CO2 spray causes thermal shock to the photoresist under the metalized layer causing large cracks in the remaining metal layer portions, said cracks typically including at least one loose metal edge. The CO2 spray is continually applied to the cracks thereby peeling away the remaining metal portions, leaving the exposed photoresist and underlying surface features. Preferably, continued treatment of the surface with CO2 snow particals erodes a surface layer of the photoresist and heavily cross-linked layers created during the metalization process. After the metal layer and the surface layer of the photoresist are removed, a simple chemical strip, such as acetone, completely removes all the remaining resist, leaving the wafer with undamaged conductor portions.
