the phase
SCR (Thyristor) phase control thyristor is short for crystal surge protective device thyratron, but also called silicon controlled flanged ball valve rectifiers, previously referred to as SCR; 1957 General Electric office 2007 professional Company developed the world's 2.4 antenna first thyristor products, and In 1958 to commercialize.
thyristor is a four-layer pigment yellow 74 semiconductor structure PNPN, it pigment yellow 12 has three pole: anode, cathode and gate; thyristor api valve rectifier device with the characteristics in high plug valve voltage, high current conditions of work , And mccb can control the course playground slide of their work, is widely used in controlled rectifier, AC voltage air flow sensor regulator, non-contact electronic switching rx safety glasses inverter, and inverter and other electronic circuits.
SCR working conditions amusement park equipment add a forward voltage and gate pump pulley trigger current; its derivative components through conduit gate valve are: fast thyristor, bidirectional thyristor, reverse thermoforming machine conducting thyristor fuel dispenser pump thyristor and so light control. It is a high-power switching semiconductor devices, the text used slitting machine in the circuit symbol for the "V" money detector "VT" that (the old standard of using metal lighter the letter "SCR" representation). Edit this pipe fittings paragraph types By off, turn and pigment red 21 control classification Its off thyristor, turn-on and hose swaging machine control can be divided golf equipment into general thyristor, bidirectional thyristor, reverse conducting stainless steel sculpture thyristor, gate turn-off pigment red 57:1 thyristor (GTO), BTG thyristor, temperature control impulse sealer Thyristor SCR and other light control.
By pin and circuit breaker polarity classification Thyristors can be time relay divided according to their pin pressure reducing valve and polarity diode thyristor, thyristor triode thyristor and the quadrupole. Sort by Package SCR can be plastic mould divided according to globe valves package metal package thyristor, thyristor plastic thyristors and three kitchen cabinets types of ceramic packages. Among them, metal t type strainer bolts encapsulated SCR is divided into pigment red 146 shape, flat shape, round shape and many cysteamine hydrochloride shell; plastic thyristor heat sink is divided into nfl shop types with and without heat sink type two.
Classified according to prada shoes current capacity Thyristor according to current cheap gucci handbags online capacity can be divided into high-power thyristors, the power thyristors and three wood plastic composite low-power thyristors. Typically, high-power thyristors to use more metal shell package, while casual shoes the medium and small power thyristor is to use more plastic or ceramic package.
thyristor remains on, the thyristor, the gate useless. 4. Thyristor in conduction case, when the main circuit voltage (or current) is reduced to near zero, the thyristor off.
