Mining flame-proof type high voltage power distribution equipment is a kind of mineral electrical apparatus; it adopts Flameproof shell structure; electric elements are all installed in explosion-proof chamber; while ensureing in main circuit, auxiliary, control and protective circuit normal work, do not produce spark or electric arc; gas or the damp that can not ignite in flameproof enclosure; once the electric elements in explosion-proof chamber produce gas or the damp that spark or electric arc ignite in explosion-proof chamber because of fault, this bus explosion separation structure can block the outside propagation of blast.
In mining flame-proof type high voltage power distribution equipment explosion-proof chamber, be provided with its major loop median generatrix of vacuum circuit-breaker and connect reliability and the bus insulation intensity that must ensure to connect explosion suppresion surface.
In prior art, realize mining flame-proof type high voltage power distribution equipment major loop bus connected mode different.Its shortcoming is: the bus of flameproof high-voltage power distribution equipment adopts naked electric conductor, and bus is nonmetallic materials through the explosion-insulation surface of the insulating sleeve of flameproof cabinet, easy to wear and volatile quick-fried, the poor low voltage grade that is only applicable to of its bus insulation strength ratio.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of flame-proof type fixed insulation bus rational in infrastructure, thereby provides reliable metal explosion suppresion surface and the intensity of becoming attached to.
The technical solution adopted in the present invention is as follows:
A kind of flame-proof type fixed insulation bus, comprise solid insulated busbar, the structure of described solid insulated busbar is: comprise conducting rod, on the outer circumference surface of described conducting rod, be enclosed with insulating body, described insulating body middle part is extended with connector, and one end of described connector is provided with flame proof inserts; One end of described solid insulated busbar is fastening by the first bolt and flameproof cabinet side plate, the other end of described solid insulated busbar is connected with input terminal by the second bolt, stud and bus plug, the outer surface of described input terminal and solid insulated busbar passes through cross fastening connector, and is positioned at cross connector top installation sealing cap.
Further improvement as technique scheme:
Four corners of described connector and flame proof inserts have the through hole of perforation, are provided with copper sheathing inserts on the outer circumference surface of described through hole;
Described solid insulated busbar adopts separate unit solid bus connection structure;
Described solid insulated busbar adopts many solid bus connection structures.
Beneficial effect of the present invention is as follows:
The present invention utilizes bus sealing technology, adopts epoxy resin that conducting rod, flame proof inserts, copper sheathing inserts are passed through to mould pressure injection, form through 24h constant temperature heat preservation solidification, has reliable metal explosion suppresion surface and dielectric strength.
The present invention adopts reliable bus connected mode, makes mining flame-proof type high voltage power distribution equipment major loop median generatrix more reliable in connecting, and has greatly improved the bus insulating property of explosion-proof electrical appliance product, thereby provides higher guarantee for electric equipment safe operation.
