Abstract
The utility model provides a conductive taper connecting device which comprises a cylindrical conductive member. A taper insulating part is sleeved on the outer cycle of the cylindrical conductive member. A grounding spring is fixedly wound in the center of the outer cycle of the taper insulating part. A conductor in a static terminal insulating part is connected with a conductor in a busbar static terminal insulating part in a conductive manner via the cylindrical conductive member, and a taper in the static terminal insulating part is closely contacted and connected with a taper in the busbar static terminal insulating part via the outer taper surface of the taper insulating part, such that the cylindrical conductive member is not affected by current temperature rise while work current is conducted. Therefore, the conductive taper connecting device has a reliable conductive function.
Description
Technical field
The utility model relates to and is used for the flame proof electric equipment products that the colliery industry receives the control of automation complete set of equipments control system, particularly the conductive connecting device of the employed aeration tank of these a flame proof electric equipment products quiet end insulation part and the quiet end insulation of a busbar part.
Background technology
The colliery industry often possibly revealed or various flammable explosive gas and the various dust of shedding that overflow in each process of the production of mining, coal separation processing, transportation and storage.After this type material and the air mixed, possibly become mixture, when the concentration of mixture reaches the explosion ratio scope, promptly can set off an explosion and serious accident such as breaking out of fire in case burning things which may cause a fire disaster occurs with explosion hazard.Therefore the electric equipment that in the hazardous environment of colliery industry, uses all must possess explosion-proof performance.
Flame-proof mine malleation high-voltage feedback power device is a kind of electrical apparatus for explosive atmospheres, and it adopts the positive pressure type structure, and electric elements all are installed in the aeration tank, guarantees the projecting pressure of pressure of aeration tank internal protection gas, in order to avoid explosive mixture gets in the aeration tank.When normal operation, aeration tank air pressure is higher than the certain numerical value of atmospheric pressure, when the inflation loading pressure is lower than certain numerical value, sends at once and reports to the police or cut off the electricity supply.The spark of device interior, electric arc do not allow from any gap, to release to the outside.The quiet end insulating part of flame-proof mine malleation high-voltage feedback power device is loaded on respectively in the different aeration tanks with the quiet end insulating part of busbar; Need be between the interior taper electric conductor of taper electric conductor in the quiet end insulating part in the adjacent aeration tank and the quiet end insulating part of busbar through being connected of conductive connecting device, this conductive connecting device need make simultaneously between tri-station isolating switch cutting blade and the vacuum circuit-breaker end of incoming cables busbar of adjacent aeration tank and conduct electricity.
Existing conductive connecting device is to utilize the cylinder claw type contact at two ends to do the usefulness of conduction connections, and its shortcoming is to lead to after operating current generation temperature rise, and the spring of this cylinder claw type contact is prone to deform, and causes the conduction contact part loose contact.
The utility model content
Be prone to come in contact bad shortcoming to existing conductive connecting device, the applicant improves through research, and a kind of conduction tapered connection device is provided, and makes electric conductivity that huge improvement arranged.
The technical scheme of the utility model is following:
A kind of conduction tapered connection device comprises a cylinder electric-conductor, is arranged with the taper insulating part on the cylindrical of said cylinder electric-conductor, and ground spring has been fastened in the middle of the cylindrical of said taper insulating part.
Its further technical scheme is: the material of said cylinder electric-conductor is a metallic copper.Said taper insulating part material is an organic material.
The useful technique effect of the utility model is:
Compare with the conductive connecting device of existing employing cylinder claw type contact; The utility model is connected the electric conductor in the quiet end insulating part of electric conductor in the quiet end insulating part and busbar by cylinder electric-conductor conduction; Taper in the quiet end insulating part of taper in the quiet end insulating part and busbar closely contacted by the outer cone surface of taper insulating part be connected; Thereby when leading in operating current, the cylinder electric-conductor does not receive the influence of electric current temperature rise, makes the utility model that reliable conducting function arranged.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the end view of Fig. 1.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1, the main body of the utility model is a cylinder electric-conductor 1, and its material is a metallic copper.Be arranged with the taper insulating part 2 that organic material is processed on the cylindrical of cylinder electric-conductor 1.As shown in Figure 2, ground spring 3 has been fastened in the middle of the cylindrical of taper insulating part 2.
After the utility model installed; Cylinder electric-conductor 1 has realized that the conduction between the interior electric conductor of interior electric conductor of quiet end insulating part and the quiet end insulating part of busbar is connected; The taper of this moment in the quiet end insulating part and the interior taper of the quiet end insulating part of busbar closely are connected the outer cone surface of taper insulating part 2; And ground spring 3 is fixed between the taper and the taper in the quiet end insulating part of busbar in the quiet end insulating part, the electric field of balanced two ends electric-conductor.The utility model also makes the tri-station isolating switch cutting blade of adjacent aeration tank be connected with vacuum circuit-breaker end of incoming cables busbar conduction.
In the utility model, the dielectric strength of taper insulating part 2 is 42KV/1min, and creepage distance is 15.5mm/kV.The surface of cylinder electric-conductor 1 is matsurface Ra0.4, and its levels is 0.2, and fit tolerance is g6.The effective area of ground spring 3 is 12.5 square millimeters, and spring pressure is 19.6N.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection range of the utility model.
