Product Description

Equipment Name: 100KW Solid State High Frequency Compact Pipe Welder

Equipment specifications: GGPY100KW

Components: main cabinet, operation console, cooling system

Equipment use: mainly used for welding ordinary carbon steel, stainless steel, aluminum and other non-ferrous metal pipes.

Features:

1. High power factor: Power factor ≥ 0.95, no additional reactive power compensation equipment is required for this equipment.

2. Energy-saving and high efficiency: Since the conventional high-frequency isolation step-down transformer is removed, the interconnection line is significantly reduced, so the reactive power loss is reduced. Tests have shown that the all-in-one machine saves about 30% compared with conventional solid-state high-frequency.

3. The output power is stable: the output ripple coefficient is small, the welded steel pipe has less burrs, the weld seam is more uniform, the finish is high, and the weld quality is good.

4. Small size, light weight, simplified connection, complete protection, fault chain protection time ≤10us, convenient debugging and maintenance, and more reliable equipment.

④ Power supply cable: plastic copper wire ≥ 75mm² per phase, ground wire ≥ 30mm²

100KW Solid State High Frequency Compact Pipe Welder it includes rectifier and inverter.

rectifier part: it is used to change the three-phase 380V AC rectifier into 0-250V adjustable DC current after voltage regulation, so as to meet the needs of the later inverter unit. Built in three-phase rectifier bridge, charging capacitor, IGBT bridge, smoothing reactor, filter device, control and protection circuit and display instrument.

Characteristics of rectifier control circuit: it is controlled by single chip microcomputer (mcs89c51) and large-scale digital integrated circuit, with high control precision, rapid response and clear state display.

Software protection mode: high over-current (9), low over-current (8), external fault (4), incoming power supply fault (phase loss, over-voltage, under-voltage, serious imbalance of three-phase voltage, display 3), cooling water fault (2), inappropriate voltage and current ratio (L), inverter fault (Y).

Hardware protection: main switch off protection, resistance capacitance absorption, resistance protection (lightning protection), fast melting protection.

inverter part: invert the 0-250 DC current sent by the rectifier cabinet into a high-frequency current of hundreds of kHz to meet the needs of welded pipes.

The inverter cabinet is composed of the following parts: power unit, channel capacitor, leakage reactance, control circuit, cooling air conditioner, etc.
