introduction：Using new equipment is a good choice，Laser cutters allow businesses to cut quickly on a daily basis，Safely cut the required material，Continuously increase productivity，Provide good opportunities for enterprises。 Let the irradiated place reach its own existing melting laser cutting machine point or boiling point，Coupled with the high-pressure gas emitted by the coaxial fittings, the metal is instantly melted or vaporized and then blown away。 Secondly, improve the labor cost of the previous laser cutting machine，Only one operator is needed to keep the entire production line running continuously for 24 hours，The attrition rate is greatly reduced。With the continuous development of the industry，Many enterprises pay great attention to the promotion of product competitiveness。Constantly moving the laser beam，Can quickly cut the workpiece，It has many characteristics。

introduction：1 Selection of circuits and devices One key point is retentiondv/dtanddi/dtAt a lower level,There are many circuits through reductiondv/dtand/ordi/dtTo reduce radiation，This also relieves the pressure on the switch tube，These circuits includeZVS(Zero voltage switch)、ZCS(Zero current switch)、Resonance mode.(ZCSA kind of)、SEPIC(Single-ended primary inductor converter)、CK(A set of magnetic structures，Named after its inventor)Etc.。 Reducing the switching time does not necessarily lead to an increase in efficiency，Because of the magnetic elementRFOscillations require buffering with strong losses，Eventually, a diminishing return journey can be observed。Using soft switching technology，Its a little less efficient，But in savings Eigensum filtering/Shielding has even greater benefits in terms of space taken up。

introduction：one、Dynamic characteristics of the approach switch The dynamic characteristics of the so-called proximity switch，Is when the input changes，Output characteristics near the switch。In practice，Some dynamic characteristics of common standard input signals are switched，To echo。This is due to the proximity switch on the standard input signal echo to test the way to acquire and near the switch specification of the input echo signal and the inevitable connection between any input signal echo，Usually knowing the former can infer the latter。Common stepper signal and sinusoidal signal and input signal specification，Therefore, the dynamic characteristics of the near switch are also commonly displayed by step echo and frequency echo。

introduction：Short-circuiter failure protection refers to when the relay protection action of the faulty electrical equipment sends a trip command and the circuit breaker refuses to operate，The protection action information of the faulty equipment and the current information of the rejected circuit breaker are used to determine the failure of the circuit breaker，It can cut out other relevant circuit breakers in the same station in a short time，Limit the power outage to a small range，So as to ensure the stable operation of the entire power grid，Avoid causing generator、Serious burnout of transformer and other faulty components and breakdown of the power grid。Generally in220kvThe above circuit breaker is configured with failure protection function，Partially important110KVCircuit breakers can also be configured to fail。

introduction：The principle of touch switch The rated voltage of the touch switch is the safe voltage when it is working normally，The rated current is the maximum safe current value that can be allowed when the touch switch is energized，Insulation resistance is the resistance between the conductor part and the insulation part of the touch switch，The insulation resistance is higher than100MΩ。The conventional range of contact resistance requirements is0.1-0.5Ωbelow，The smaller the value, the better。Voltage resistance is the high value of the voltage that the touch switch can withstand between the conductor and the ground。Touch switch service life when sensing switch operating environment，The number of times that can be used in5000-35000Time or so。
