Abstract
The utility model discloses an electric heating rod connection device in the field of oil exploitation, which aims to solve the technical problem that the existing terminal block is not capable of high-temperature resistant and is easy to deform during the working process, and has short service life, and comprises a cover plate coved upon a box body, wherein the box body is connected with a base, the box body is internally provided with a fixed support and a terminal block, the terminal block is of a ceramic terminal block, the ceramic terminal block is provided with a central hole, and is fixed on the fixed support through bolts, the periphery of the central hole is distributed with a plurality of terminal mounting holes, and the terminals are arranged in the terminal mounting holes. The utility model is high-temperature resistant, better on heat dissipation, and suitable for the heating rod system and can meet the requirement of the normal working under the high-temperature environment.
Description
Technical field
The utility model relates to a kind of termination, particularly the termination of a kind of electric heating bar of field of petroleum exploitation.
Background technology
In the prior art, along with going deep into of oil field development, the exploitation ratio of some high viscosities, high-solidification point, high wax content oil is increasing.For these oil reservoirs of economical and efficient ground exploitation, the characteristics poor at the viscous crude flowability, that temperature sensitivity is high adopt electric heating sucker rod production technique to cooperate other technologies can adapt to the exploitation of heavy crude reservoir preferably.Existing a kind of electric heating lever system, the termination of its electric heating bar, the box body that mainly comprises hollow, the box body top is provided with cover plate, described box body bottom and base link together, be provided with slot and terminal block in the box body, terminal block is provided with binding post, and terminal block is plugged in the slot and is fixed, during work, by base and heating pole fixed installation, its shortcoming is under the high-temperature work environment, and terminal block, binding post poor radiation are yielding, cause lead to blow the rate height, and then increased production cost.
The utility model content
The purpose of this utility model is can not be high temperature resistant at the binding post in the existing heating pole system, and yielding problem provides a kind of electric heating bar termination, can be in operate as normal under the hot environment, failure rate is reduced, reduce production costs, enhance productivity.
For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of electric heating bar termination, the box body that comprises hollow, the box body top is provided with cover plate, described box body bottom and base link together, be provided with fixed support and binding post in the box body, described fixed support is screwed on base, described binding post is ceramic patchboard, this pottery patchboard has a centre bore, be installed on the fixed support by the bolt that passes centre bore, several binding post installing holes that distributing around the described centre bore, described binding post installing hole is equipped with binding post.
Compare with termination of the prior art, the advantage of above-mentioned electric heating bar termination is: when operate as normal, under 20 degrees centigrade of the ambient temperatures, the wire connection cavity surface temperature is 65 degree, and the fusing point of ceramic patchboard can satisfy environmental requirement more than 1000 degree; The pottery patchboard is good electrical insulating material, and mechanical strength is good; The cross section of wire connection cavity is a disc, has guaranteed the utilization rate in space, helps the connection of lead, thereby improved the efficient of producing, simultaneously, circular configuration can be to heat radiation all around, its radiating efficiency height, ceramic patchboard and support bracket fastened mounting structure make the thermal diffusivity of box body inside strengthen by force.The utility model is simple in structure, and process and assemble is convenient, can satisfy the requirement of operate as normal under the hot environment, and also can provide the improvement of user's existing equipment may.
As further improvement of the utility model, described each binding post installing hole equates with the centre bore distance, can guarantee Homogeneouslly-radiating.Binding post can adopt copper material to make, and has good electrical conductivity and thermal diffusivity.For making things convenient for the connection of cable, symmetry has two cables import and export on the sidewall of described box body.
