GB/T 8366-2004 Mechanical and electrical requirements for resistance welding machines
Some standard content:
The standard is revised to adopt IS669-2930. The reason why GB/T 8366-2004 is revised to adopt IS669-2930 is that the cooling water pressure that the cooling circuit can withstand in 14MP in 1365 is changed to 0.5MP. After that, the water supply system of civil and industrial use in my country cannot reach the pressure of 1MP. In addition, if the industry adopts a circulating water system, the supply and demand pressure of the circulating water system is usually set at 3MP. Therefore, the pressure of 1 in TSO553 does not meet the national standards. Compared with GB/T8366-1906, this standard has the following changes: the applicable range of the standard has been expanded: the original standard is only applicable to single-phase alternating current machines: this standard is applicable to single-phase and single-phase alternating current machines, and the technical definition of resistance welding has been changed.
The rated no-load voltage at the transmission end is required. The temperature rise limit of the surface of the equipment is increased. This standard is the main standard for human standards, and the appendix is an informative appendix. This standard replaces GB/T3366-1995 from the month of implementation. The National Electrical Industry Association proposed this standard. This standard was drafted by the Technical Committee of the National Standardization ... The welding guns and mobile welding machines with transformers are classified into the following types:
single-pole AC furnace machine;
single-pole secondary fast current wide welding machine:
single-phase inverter electric welding machine:
three-phase secondary current resistance welding method
one-phase integrated rectifier output phase (with attached inverter) three-phase inverter type welding machine,
this clause can only specify safety requirements, nor is it applicable to welding transformers produced separately. 2 Normative reference documents
