Description
Technical field
The present invention relates to insulating oil technical field more particularly to a kind of insulating mineral oil.
Background technique
Currently, insulating oil is broadly divided into mineral insulating oil, synthetic insulating oil, vegetable insulating oil and mix insulation oil.Mineral
Oil has outstanding advantages of cheap, excellent insulating property, condensation point are low, viscosity is small, is most widely used in oil immersed type heat dissipation
Insulating oil.But mineral oil is a kind of non-renewable fossil energy, and flash-point, burning point and water saturation are lower, biodegrade
Property it is poor, once leakage water source, living environment etc. will be polluted, be unsatisfactory for the requirement of environmental type insulating materials.Closely
Over 20 years, the research for finding mineral insulating oil substitute causes the extensive attention of domestic and foreign scholars, and achieves and attract people's attention
Progress.Existing substitute mainly includes two major classes: synthetic insulating oil and vegetable insulating oil.Synthetic insulating oil has excellent
Physicochemical property, can match in excellence or beauty with mineral insulating oil in most of performance parameters, but due to its is expensive and manufacturing device and
The complexity of technical conditions limits its further popularization and application.Vegetable insulating oil has good electric property, and flash-point is high
In 300 DEG C, biological degradation rate is up to 97%, and saturation moisture content is high, and environmental protection is renewable, meets wanting for electrical equipment fire protecting performance
It asks, and can effectively delay insulating paper aging, it is considered to be the best substitute of mineral insulating oil.Compared with mineral oil, plant
Insulating oil has higher electrical strength, higher burning point and flash-point, has in terms of promoting lithium battery capability of overload very big
Superiority, but the vegetable oil determined due to natural esters own molecular structure characteristic is had that condensation point is high, oxidation stability is poor, viscous
Degree, the disadvantages of acid value and dielectric loss are high, so that vegetable insulating oil performance parameter, especially viscosity, dielectric loss and acid value can not expire
The standard of the existing lithium battery insulating oil of foot needs to carry out weight to key structures such as insulation, heat dissipations filling in existing lithium battery
New design, to meet the exfactory inspection and safe operation demand of lithium battery.
With the propulsion of grid equipment whole-life cycle fee, to the thermal stability of paper oil insulation material, delay insulation old
Changing performance, environmental-protecting performance etc., more stringent requirements are proposed.
