Q:What is the thermal aging and electrical aging of insulating materials?
Insulation materials in electrical equipment during the operation, due to the long-term effects of various factors, there will be a series of irreversible physical and chemical changes, resulting in its electrical performance and mechanical properties decline, commonly known as aging. There are many factors that affect the aging of insulating materials. The main aging forms are environmental aging, heat aging and electrical aging.
Q:What is the DMD insulation material?
These small mirrors are approximately 16 or 14 microns in size and are usually made up of an array of up to 50 to 2 million, with a gap between the mirrors of 1 micron and a mirror rotating with an aluminum hinge as a rotation axis 10- 12 degrees, can be used repeatedly 1 trillion, life test shows that in accordance with the usual use can be used for 100,000 hours. Its opening and closing control is through the mirror stop when the damping effect of the spring contact near the mirror, gradually reduce the way the additional voltage to achieve. DMD chip has been upgraded, the original chip on the microscope size of 16 microns, flip angle of 10 degrees, the current DMD micrometer size of 14 microns, flip 12 degrees, support 4K resolution chip has also been formed, the chip size of about 1.38 Inch.
Q:What insulating material is best `?
The earliest use of insulating materials is cotton, silk, mica, rubber and other natural products .20 century 30 years later, the rapid development of synthetic insulation materials, a variety of synthetic resin, plastic, etc. used in the field of electrical engineering to manufacture motor and high and low pressure Electrical appliances, so that the capacity of electrical products continue to expand, the volume gradually reduced, so as to promote the development of electrical and electronic technology.
Q:What insulating materials are used for transformers
Dry type transformers before the 1960s are mainly B-type insulation of the open-type dry-type transformers, product model for the SG type. When there is no foil coil, the low pressure for the majority of multi-root and around the layer or spiral coil, high pressure for the pie coil. Wire for the double glass envelope or single glass fiber package enamel enameled wire. The rest of the insulating material is mostly phenolic glass fiber materials. The impregnation process for the room temperature, atmospheric pressure with B-class insulation impregnated paint were high and low pressure coil impregnation and drying at the temperature (drying temperature does not exceed 130 ℃). Although this dry-type transformers than oil-immersed transformers in the fire performance has made great progress, but its moisture, anti-pollution performance is worrying. Is no longer produced. Nevertheless, its successful electrical, magnetic, thermal calculations and structural design have laid a good foundation for the new H-class insulated open-ended transformers that have evolved later.
Q:Wear-resistant, high temperature, insulation materials which
Alumina - high temperature, corrosion resistance, wear resistance. Good electrical insulation 1600 ℃. For crucible, high temperature thermocouple casing, knives, mold and so on. Silicon nitride - has good high temperature strength, thermal expansion coefficient is small, high thermal conductivity, thermal shock resistance, the use of temperature as alumina, good electrical insulation. 1200 ℃ still have a high hardness. For mechanical seal ring, thermocouple casing, steam turbine blades and so on. Silicon carbide - high temperature strength, 1400 ℃ when the bending strength of (500 ~ 600) MPa. For the nozzle, furnace tubes, high temperature bearings, high temperature heat exchangers and so on.
Q:What is the 8 ° C rule for insulating materials?
Such as A-class insulation material limit working temperature of 105 ℃, when the ultimate operating temperature of 8 ℃, its life will be reduced by about half, which is 8 ℃ thermal deterioration rules.
Q:The role and definition of insulating materials
Its resistivity is very high, usually in the range of 10 ^ 9 ~ 10 ^ 22Ω · m. Commonly used insulating materials according to their different chemical properties, can be divided into inorganic insulating materials, organic insulating materials and mixed insulation materials. Commonly used inorganic insulation materials are: mica, asbestos, marble, porcelain, glass, sulfur and so on,
Q:What kind of insulation is the insulating layer of the aluminum plate?
Ordinary heat conduction is made with fiberglass PP2. High thermal conductivity materials are made of thermally conductive
Q:What insulating materials are used for high frequency transformers?
In the production process of high-frequency transformers, insulation is a crucial step, this time you need to use a kind of insulation called the water, that is, paint. A class of artificial paint, shiny, good sticky. It is a paint that does not contain coloring matter. When applied to the substrate, it can form a transparent film with protection, decoration or special properties.
Q:What are the electrical insulation materials
Many types of insulating materials, can be divided into gas, liquid, solid three categories. Commonly used gas insulation materials are air, nitrogen, sulfur hexafluoride and so on. Liquid insulation materials are mainly mineral insulating oil, synthetic insulating oil (silicone oil, dodecyl benzene, polyisobutylene, isopropyl biphenyl, diaryl ethane, etc.) two categories. Solid insulation materials can be divided into organic, inorganic two categories. Organic solid insulation materials include insulating varnishes, insulating glue, insulating paper, insulating fiber products, plastic, rubber, lacquered lacquers and insulating impregnated fiber products, electrical thin films, composite products and adhesive tape, electrical laminates and so on. Inorganic solid insulation materials are mainly mica, glass, ceramics and their products. In contrast, solid insulation material variety, but also the most important. Different electrical equipment requirements for the performance of insulating materials are focused. High-voltage electrical equipment such as high-voltage motors, high-voltage cables and other insulation materials require high breakdown strength and low dielectric loss.
