GB 19212.4-2005 Safety of power transformers,power supply units and similar devices.Part 4: Particular requirements for ignition transformers for gas and oil burners (English Version)
This chapter of GB/T 19212.1-2003 is replaced by the following content: This part specifies the safety requirements for various aspects of transformers (eg electrical, temperature and mechanical aspects). This part applies to transformers for stationary, single-phase, air-cooled (natural or forced cooling), supporting (built-in or non-built-in) gas and oil burner ignition systems, whose rated power supply voltage does not exceed AC 1000V, The rated frequency does not exceed 500Hz, and the rated output current does not exceed 500mA. No-load output voltage and rated output voltage should not exceed AC 15000V. This standard applies to transformers that do not require double insulation or reinforced insulation between circuits according to installation procedures or equipment specifications. This section applies to dry-type transformers. Its windings can be hermetically sealed or unsealed. This standard applies to transformers containing electronic circuits. This standard does not apply to external circuits and their components intended to be connected to the input terminals and output terminals or sockets of the transformer.
