Product composition150kW Solid-State High Frequency Integrated
WelderProduct IntroductionIntegrated 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, 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
welder.Technical parameters: 1Nominal power150kW2Rated DC
