Enterprise standard Q/SCD 001-2000 "silicon, silicon controlled rectifier standard"
2. Main technical parameters:
rated output voltage: + 15 V.
rated output current: 3000 A.
input power: 380 + / - 10%, 50 to 60 hz;
voltage ripple coefficient of 1% or less
stable voltage, stable current accuracy of + / - 1%;
soft start time adjustable 0-180 seconds;
load rating for the "I", that is, 100% rated current work continuously.
3. Product features:
① It has the function of automatic voltage stabilizing and current limiting, current stabilizing and pressure limiting.
● Voltage stabilizing and current limiting function: when the rectifier works in this state, if the load changes, the voltage is stable and the current changes with the load. When the current reaches or will exceed the rated current, it will automatically be in the current limiting state, that is, the maximum current will not exceed the rated current.
● Current stabilizing and voltage limiting function: when the rectifier works in this state, if the load changes, the current will be stable and the voltage will change with the load. When the voltage reaches or will exceed the rated voltage, it is automatically in the voltage limit state, that is, the maximum voltage does not exceed the rated voltage.
② It has high and reliable over-current and short-circuit protection function.
When the load current exceeds 50% of the rated value, the rectifier will automatically block the output pulse, the operation time is 10ms, and it will be maintained until the shutdown.
③ has the function of phase loss protection
When the three-phase power line is missing phase, the rectifier will automatically block the output pulse, the operat
ion time is 10ms and the voltage of the three-phase power supply is normal.
④ The product is equipped with remote program control box or a computer central control system for the use of multiple machines (need to be specified when ordering).
(5) Cycle reversing can be single cycle or complex cycle, time is arbitrary. (To be stated when ordering)
The main transformer adopts two vacuum dip paint or hot dip paint, drying.
The three-phase integrated trigger control board has multiple protective measures, is a novel high threshold anti-interference strong integrated double pulse trigger circuit, advanced performance, good output waveform, reliable operation, convenient debugging.
⑧ With soft start function, prevent large current impact, to ensure the quality of the coating.
⑨ Using computer standardized design, plastic spraying case, anticorrosive and beautiful.
Three, the working principle
① Main circuit working principle
●SKDF-12X twelve phase ultra-low ripple thyristor cycle commudation rectifier using the original side thyristor voltage regulation, two △/Y- and Y/Y- people composed of twelve phase rectifier transformer. The secondary side is composed of SCR inverse parallel contactless commutator and integrated control circuit.
The original side thyristor voltage regulation to implement output DC voltage stepless voltage regulation and automatic control of various functions, the auxiliary side thyristor by the cycle commutation control circuit to implement contactless commutation;
● 12 phase rectifier output after the use of LC filter, so that the voltage ripple coefficient is less than 1%, the performance can be fully comparable with the imported similar products.
