The composite switch should be a mechanical contact switch (general light switch, small motor switch). Its shortcoming is that there is a spark when compounding, and the larger the current, the larger the spark, and the easier it is to penetrate the air in the high voltage circuit. Causes malfunction. The non-contact switch is controlled by a thyristor because it is turned on and off inside the PN junction, so there is no spark, and its high pressure resistance is also good. Like some large When the motor is started, the inertia of the rotor from static to rotation is very large, resulting in a large starting current (substantially equivalent to short-circuit current). When the machine is stopped, it is operated by inertia, resulting in a very high voltage. The capacitive non-contact switch is On the basis of the thyristor switch, add throttling and decompression bypass resistors and capacitors to absorb large currents and discharge high voltages.

Nickel And Nickel Alloys

Nickel is a versatile, highly corrosion resistant element that will alloy with most metals. Due to its corrosion resistance, nickel is used to maintain product purity in the processing of foods and synthetic fibers. It is highly resistant to various reducing chemicals and is unexcelled in resistance to caustic alkalies. In addition, nickel has good thermal, electrical and magnetostrictive properties. Relatively high thermal conductivity of this metal has lead to its frequent use for heat exchangers

Commercially pure or low-alloy nickel may contain very small amounts of alloying elements to absolutely none. By contrast nickel alloys contain significant amounts of added elements. Nickel and nickel alloys are both non-ferrous metals that are useful in a range of applications, most of which involve corrosion resistance and/or heat resistance.
