Mga teknikal na parameter ng thyristor intermediate frequency power supply cabinet

1. The main technical parameters of KGPS-500/0.5 intermediate frequency power supply are as follows:

2. BSC8M-2 main control board : the core components adopt American ASIC2 high-density integrated circuit block, with phase sequence adaptive circuit, inverter adopts sweep frequency zero voltage start mode, frequency tracking circuit adopts average sampling scheme, inverter circuit There is an inverter angle adjustment circuit in the addition, which can automatically adjust the matching of the load impedance. It has the function of overload starting and material shortage protection.

3. Function and protection: The core digital circuit of the main control board has 31 input/output interfaces. The internal functions include rectifier phase shift trigger, phase sequence adaptive, inverter trigger, inverter lead angle lock, inverter repeated start and main Control panel undervoltage automatic protection and other functions.

◇ Main circuit short circuit protection

◇ Main circuit lack phase protection

◇ Proteksyon ng mataas at mababang grid voltage

◇ Proteksyon sa mababang presyon ng tubig sa paglamig

◇ Proteksyon sa temperatura ng tubig na may mataas na paglamig

◇ SCR over-voltage and over-current protection

◇ Load overvoltage and overcurrent limit

4. Filtering reactor: Ang silicon steel sheet na napili para sa reactor ay ang Z10 cold-rolled high permeability silicon steel sheet na ginawa ng Wuhan Iron and Steel. Ang copper tube ay nasugatan ng T2 oxygen-free na copper tube na ginawa ng Luoyang Copper Material Factory. Double winding wire package, balot ng mika tape, H-class insulation, gumaganang ingay ay mas mababa sa 70 decibels;

5. Universal circuit breaker: The circuit breaker of the front switch cabinet of the intermediate frequency power supply selects the DW-17 model;

6. Operation panel: May mga metro sa panel tulad ng DC voltage, DC current, intermediate frequency voltage, intermediate frequency power, intermediate frequency frequency, atbp. Nilagyan ng AC opening/closing, intermediate frequency start/stop, fault reset buttons, over-current, over-voltage indicator lights, internal/external control switch at power adjustment potentiometer. Ang power output ng inverter ay maaaring i-adjust nang arbitraryo sa loob ng saklaw na 10% hanggang 100%.

7. The cooling water protection system of the inverter: the intermediate frequency power cabinet adopts closed cooling water, and the thyristor and reactor are equipped with water temperature protection. When the water temperature exceeds the rated value, the inverter will automatically shut down; all inlet and outlet water pipes are made of stainless steel.

8. Ang panlabas na istraktura ng inverter: ang panlabas na istraktura ay isang karaniwang GGD cabinet, tatlong-pinto na cabinet, ang kabuuang sukat (haba × lapad × taas): 2400 × 900 × 2000mm, ang cabinet shell ay na-spray at ang kulay ay magaan. berde .
