Technical field
The present invention relates to power switchgear accessories technical field, and in particular to a kind of epoxy resins insulation cap.
Background technology
Epoxy resin is to refer to the organic compound containing two or more epoxide groups in molecule, in addition to indivedual,
Their relative molecular mass is not high.The molecular structure of epoxy resin is to contain active epoxide group in strand as it
Feature, epoxide group can be located at the end of strand, centre or circlewise structure.Due to containing active ring in molecular structure
Oxygen groups, them are made to crosslink reaction with polytype curing agent and form the insoluble height with three-dimensional network structure
Polymers.The high-molecular compound containing epoxide group is referred to as epoxy resin in all molecular structures.Epoxy resin tool after solidification
There are good physics, chemical property, its surface to metal and nonmetallic materials has an excellent adhesive strength, and dielectric properties are good
Good, deformation retract rate is small, and product size stability is good, and hardness is high, and pliability is preferable, to alkali and most of solvent-stable, thus
It is widely used in national defence, each department of national economy, pours into a mould, impregnates, the purposes such as lamination material, bonding agent, coating.
Due to the advantages of insulating properties of epoxy resin are high, structural strength is big and good seal performance etc. is many unique, exist
It is used widely, have developed rapidly in the insulation and encapsulation of high and low voltage electrical equipment, motor and electronic component.It is mainly used in：Electrical equipment,
The cast of motor insulating envelope.Such as electromagnet, contactor coil, transformer, the entirety of dry-type transformer high and low voltage electrical equipment
The manufacture of hermetically sealed insulating envelope.It is developed rapidly in electrical equipment industry.Had developed to from normal pressure casting, vacuum pouring
Automatic pressure gel is molded.
Epoxy resin is a kind of to have high dielectric property, resistance to surface leakage, resistance to due to epoxy-resin systems after its solidification
The superior isolation material of electric arc；Epoxy-resin systems after solidification have excellent mechanical property；Epoxy resin body after solidification
System has excellent alkali resistance, acid resistance and solvent resistance.Epoxy resin is highly suitable for the cladding master in high-tension switch gear
APPENDIX MATERIALSThe in the insulating materials and high-tension switch gear in loop as insulating materials.Major loop in existing high-tension switch gear
Electric-conductor mostly using airbreak laying installation, do not carry out cladding sealing protection to electric-conductor, short circuit easily produced between circuit
Or the external world is discharged, while electric-conductor also exacerbates the extent of corrosion of electric-conductor with air contact for a long time, shortens height and presses off
Close the service life of equipment.
The content of the invention
The technical problems to be solved by the invention are deficiencies of the prior art, and it is an object of the present invention to provide a kind of epoxy resin is exhausted
Edge cap.
The present invention is achieved through the following technical solutions：
A kind of epoxy resins insulation cap, the insulator cap are the hollow circular cylinder of one end open.
