Product composition300kW Solid-State High Frequency Integrated
WelderIntegrated welderThe integrated design of the switch and the
rectifier part, in addition to the function of the switch cabinet,
also has the rectifying control function of the solid-state high
frequency welder.1) Installed 3-phase full-controlled
thyristor rectification bridge to realize power adjustment of the
high frequency welder.2) Installed flat-wave reactor,
flat-wave capacitor and filter to improve the flat-wave
coefficient.3) Protection reactor, ammeter, and current hall sensor
are installed to protect and monitor the inverter bridge.4) Siemens
S7-1200 PLC is installed to realize power logic control and
Ethernet communication functions. Control desk1) Adopt
stainless steel operation penal with beautiful appearance and easy
to clean.2) Add touch screen protection cover to improve the
service life of touch screen.3) The touch screen of the control
desk has data recording function for important parameters and
information, which is convenient for historical query. Meanwhile,
it has visual data record, which is convenient for analysis and
viewing the status information of the equipment.4) It has the
functions of remote operation, power regulation, state monitoring
and fault diagnosis of HF welder.5) Ethernet interface is reserved
to facilitate the user's function expansion and realize remote
monitoring and information collection.6) The function can be added
and expanded according to the actual needs of users.
2-D positioning tableIt is used for fixed installation of
welder and position adjustment of the work coil. 2-D positioning
table is adopted: manual adjustment in front / back, left / right
direction, stable and reliable adjustment, so as to ensure that the
work coil is always in the best welding position. Air-water
coolerAir-water heat exchanger is adopted. And circulation soft
water is used as cooling water with temperature and water level
indicator and protection, which can perfectly accomplish the
cooling work for integrated welding unit and resonance tank
circuit. 304 stainless steel is adopted for water tank and in-line
pump. Measures for high efficiency and energy saving1)
PSM technologyWith the latest PSM inverter control technology
(Pulse Shielded Modulation), when welding steel pipes of different
specifications, the welder can ensure a constant DC voltage of 450V
and output power continuously adjusted. At this time, the welder
has the highest grid side power factor, the minimum input current
and the best welding efficiency.2) Integrated inverter bridgeAdopt
the optimized integrated inverter bridge with small stray loss.3)
Welding frequency optimizationWith optimal design of resonance tank
circuit, the frequency of the welder is 20% - 30% higher than the
original design and effectively improve the welding efficiency.4)
Welding process optimizationAccording to the tube mill
specifications and tube type, optimize the structural design of the
output lead. Technical advantages1) Energy saving - PSM
technology effectively solves the load matching problem of
solid-state HF welders and lays the foundation for high efficiency
and energy saving.2) Reliability - the Integrated inverter bridge
significantly improve the reliability and stability of the
solid-state HF welder.3) Intellectualization - Full digital control
system improves the automatic management level of solid-state HF
