Abstract
The utility model relates to an outdoor small-volume installing box for a current transformer, and more specifically, the outdoor small-volume installing box for a current transformer is used in an oil well remote monitoring system of an oil field. The utility model is mainly composed of a box body, a box cover, cable penetrating holes, threading holes, a fixing bracket for a connection holder and a bottom end cover, wherein the cable penetrating holes are respectively connected with an insulating pipe, and the cable penetrating holes are communicated with the cable penetrating holes at the bottom end cover through the insulating pipes; the bottom of the box body is provided with an opening, and the bottom end cover is connected with the opening through bolts; the box body is provided with the fixing bracket; the inner wall of the box cover is provided with a sealing rubber pad, and the bottom end cover is also provided with the threading holes and fixing holes of the bottom end cover. The utility model has the advantages that the utility model adopts a direct penetrating method, and a transformer installing box having a sealing function is utilized to make cables and connecting lines respectively enter the insulating pipes of the cable penetrating holes and the threading holes; the utility model makes full use of space between a power distribution cabinet and an oil pumping machine, and the transformer installing box is arranged in the space; the utility model can ensure insulation; besides, the utility model is sealed, therefore the utility model can effectively prevent rainwater from entrance.
Description
(1) technical field
The utility model relates to a kind of current transformer install bin, is specially the open-air small size current transformer install bin that the oilfield remote measuring and controlling system is used, and the instrument transformer of interior dress is used to measure the current of electric of oil well.
(2) background technology
Be used to measure the instrument transformer of current of electric in the oilfield remote measuring and controlling system in the past, usually be installed in the power distribution cabinet, and along with technology innovation and antitheft needs, the oil field begins to change novel power distribution cabinet, this power distribution cabinet volume is little, be retrofitted on the terminal box of motor, the inner space that current transformer is not installed can't be installed the current transformer in the remote measuring and controlling system.If install an instrument transformer special box when TT﹠C system is installed again additional, because cable does not have surplus capacity, to making the cable can not be crooked and still can't install.
(3) summary of the invention
The utility model is for remedying the deficiencies in the prior art, a kind of rational in infrastructure, easy to use, small size is provided, can utilizes confined space installation, waterproof, stable performance, attractive in appearance, the open-air small size current transformer install bin that need not the cable bending.
The utility model is finished by following technical measures.
This instrument transformer install bin mainly is made up of casing, case lid, through cables hole, through wires hole, junction block fixed mount, bottom cover, wherein, is connected with insulated tube on the through cables hole, communicate with through cables hole on the bottom cover by insulated tube.
Be provided with opening on bottom half, bottom cover connects thereon by bolt.
Fixed mount is arranged on the casing.
The casing upper end is provided with the sealing platform.
On the inwall of case lid, be provided with sealing rubber pad.
Also have through wires hole and bottom cover fixing hole on the bottom cover.
The utility model beneficial effect is: one, adopt and directly pass mode, by being provided with the instrument transformer install bin of sealing function, cable and line are entered respectively in the insulated tube of through cables hole and through wires hole, and cable need not increase length and bending; Two, make full use of space between power distribution cabinet and the oil pumper, the instrument transformer install bin of installation, specious; Three, wearing the cable pipe adopts nonmetallic materials, guarantees insulation; Four, sealing effectively prevents entering of rainwater.The utility model also has advantages such as rational in infrastructure, esy to use, safe and reliable.
