Description
Technical field
The present invention relates to mine explosion-suppression electric product technical field, especially a kind of flame-proof type fixed insulation bus controlled by automation complete set of equipments control system for colliery industry.
Background technology
In each process that colliery industry is produced in coal mining, coal separation is processed, transport and store, often may reveal or excessive shed various flammable explosive gas and various dust.After this kind of material mixes with air, the mixture with explosion hazard may be become, when the concentration of mixture reaches explosion ratio scope, once occur that namely burning things which may cause a fire disaster can set off an explosion and the serious accident such as breaking out of fire.Therefore the electric equipment used in the hazardous environment of colliery industry all must possess explosion-proof performance.
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; ensure main circuit, assist, control and do not produce spark or electric arc during normal work in protective circuit; can not be ignited gas in flameproof enclosure or damp; once the electric elements in explosion-proof chamber are because of the gas in fault generation spark or arc ignition explosion-proof chamber or damp, this bus explosion separation structure can block blast and outwards propagate.
Be provided with its major loop median generatrix of vacuum circuit-breaker in mining flame-proof type high voltage power distribution equipment explosion-proof chamber and connect the reliability and bus insulation intensity that must ensure to connect explosion suppresion surface.
In prior art, realize mining flame-proof type high voltage main loop of power distribution 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, and easy to wear and volatile quick-fried, its bus insulation strength ratio is poor is only applicable to low voltage grade.
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, thus provides reliable metal explosion suppresion surface and 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, and the outer circumference surface of described conducting rod is enclosed with insulating body, be extended with connector in the middle part of described insulating body, one end of described connector is provided with flame proof inserts; One end of described solid insulated busbar by the first bolt and flameproof cabinet side plate fastening, 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 by 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 through through hole, the outer circumference surface of described through hole are provided with copper sheathing inserts;
Described solid insulated busbar adopts separate unit solid bus connection structure;
Described solid insulated busbar adopts multiple stage solid bus connection structure.
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 mould pressure injection, formed through 24h constant temperature heat preservation solidification, has reliable metal explosion suppresion surface and dielectric strength.
The present invention adopts reliable bus connected mode, more reliable during mining flame-proof type high voltage main loop of power distribution median generatrix is connected, and substantially increases the bus insulating property of explosion-proof electrical appliance product, thus provides higher guarantee for electric equipment safe operation.
