The terminal is used to achieve a product of the electrical connection fittings, the connector is divided into areas of industry. With the increasingly high degree of industrial automation and industrial control requirements more stringent, precise dosage terminals gradually rise. With the development of the electronics industry terminal wire outlets, terminals use of more and more, and more and more types. Currently the most widely used in addition to the PCB terminals, there are hardware terminals, nuts terminal, spring terminal, and so on. Insulation coordination is defined according to the requirements of the product and the surrounding environment to select electrical insulation properties, only in its lifetime endured a variety of roles (such as voltage and other factors) based on the strength, to achieve the ultimate goal of product insulation coordination. Three Bay Electric Technology Department in reference to all the information in the final summary of the following: insulation coordination principles, low-voltage equipment for insulation coordination requirements of low-voltage electrical terminals in the application and design requirements: insulation coordination principles of insulation co-ordination 1, insulation damage and influencing factors. One is the breakdown (thermal breakdown) that is in a strong electric field, electric internal media due to dielectric loss and fever, if the heat dissipation of the terminal line price was too late, the temperature continues to rise, leading to low molecular weight volatiles The molecular structure of the material will escape physical destruction terminal wire manufacturers, finally resulting in insulation breakdown; insulation breakdown factors: temperature - the temperature rises, the breakdown voltage of the material decline humidity - humidity increases, the breakdown voltage of the material decline Voltage - voltage action time increase the role of time, material breakdown voltage drop frequency - the frequency increased, the breakdown voltage of the material decline in material thickness - material thickness increase, heat unfavorable, the other for the breakdown voltage drop that is insulating materials insulation aging equipment a variety of factors during the operation, the occurrence of physical and chemical changes irreversible, leading to dramatic changes in electrical materials, mechanical properties and damage to insulation aging. Such as: thermal aging, alone or in the insulating material under the combined effects of heat, oxygen, water, or low molecular weight volatile products to escape; chain reaction to generate radical molecules involved in strand; autocatalytic acceleration caused material damage; produce hydrolytic degradation; or produce polymer chain polymerization, leading to performance degradation or complete destruction of the material; the other electrical aging, due to O3, NOx, and other high-speed particles produced by partial discharge and partial discharge caused by dielectric loss increase resulting Materials fever, lead to material degradation or complete destruction terminal wire manufacturers |.
