introduction
All electrical and electronic products must be designed with fire risk and potential fire hazard in mind. Design of components, circuits and products, and
The purpose of the screening of materials is to reduce the potential risk of ignition to an acceptable level in the case of reasonably foreseeable abnormal use, failure or failure.
Level.
For more than 100 years, mineral oil insulating liquids have been used for insulation and cooling of transformers and other types of electrical equipment.
Synthetic insulating liquids have been developed and used over the past 70 years, and their performance is especially suitable for special electrical applications. However, due to technology and
For reasons of economy, high-refined mineral oil continues to be widely used as a insulating liquid in transformers and is its main use. Regional, national and international law
The specification includes its secure installation.
For mineral oils and synthetic liquids, the fire safety record for electrical and electronic products containing insulating liquids is good. In recent years
Improvements in fire protection design and measures have reduced the risk of fire in electrical equipment containing mineral oil. However, for all electricians
In the case of equipment, the aim is to reduce the possibility of fire even in the event of foreseeable abnormal use.
The actual goal is to prevent light-off. If a light-off occurs, it is best to control the fire inside the enclosure of the electrical equipment.

4 insulation liquid classification
Insulating liquids have been classified according to ignition point and net heat of combustion in IEC 61039, as shown in Table 1.
Table 1 Classification of insulating liquid
Burning point net heat of combustion
O grade ≤300°C Level 1 ≥42MJ/kg
Class K>300°C Level 2
<42MJ/kg
≥32MJ/kg
Class L non-measurable ignition point level 3 <32MJ/kg
Example. Mineral transformer oil (IEC 60296) is classified as O1.
Note 1. Measurement of the ignition point using the ISO 2592 Cleveland Open Cup method is the preferred method of grading.
Note 2. The measurement of flash point is sometimes used as a second method for grading. IEC /TC10 is usually measured by the flash point test method (closed cup method) of ISO 2719.2002 [3]
