Summary of the invention
In view of this, the object of this invention is to provide a kind of transformer current instrument transformer easy mounting structure of novel structure, effectively provide production efficiency, reduce the height of transformer belt sleeve pipe transport, cost-saving; Meanwhile, the present invention also provides a kind of installation method of transformer current instrument transformer easy mounting structure.
First specific embodiments of the present invention is: a kind of transformer current instrument transformer easy mounting structure, comprise transformer box cover and be located at the sleeve pipe on case lid, the current transformer be positioned at immediately below sleeve pipe is provided with bottom case lid, described current transformer is series in the inlet wire cable of sleeve pipe, is positioned at the supporting plate being provided with to lift current transformer below current transformer; Be positioned at above case lid and be also provided with connecting terminal box, described current transformer is electrically connected with described connecting terminal box.
Further, described case lid is positioned at and is provided with through hole bottom connecting terminal box and is electrically connected with current transformer through through hole in order to the binding post of connecting terminal box.
Further, be positioned at sleeve pipe perimembranous and be fixed with screw rod bottom described case lid, described screw rod is from top to bottom through the nut check be positioned at after the bolt hole on supporting plate on the downside of supporting plate.
Second specific embodiments of the present invention is: a kind of installation method of transformer current instrument transformer easy mounting structure described above, comprises the following steps: (1) is positioned at cannula mount hole week side welding screw rod bottom case lid; (2) mounting sleeve in the sleeve pipe bore on case lid; (3) the inlet wire cable of joint sleeve, and current transformer is connected in inlet wire cable; (4) supporting plate is installed on screw rod to support current transformer; (5) on case lid, install connecting terminal box, the binding post of connecting terminal box through the through hole be positioned at bottom it, and utilizes wire to be coupled together by the binding post summation current transformer of connecting terminal box.
Compared with prior art, the present invention has following beneficial effect: (1) compact conformation, rationally effectively make use of the space that transformer tank covers, and makes product more succinctly attractive in appearance; (2) production installation process is simplified, and need not make rising seat, is in the manufacturing process of case lid or is all simplified at the fit in workman's later stage, improves production efficiency; (3) height of transformer belt sleeve pipe transport can be reduced, effectively can avoid that current transformer is installed and adopt transformer belt sleeve pipe shipping height superelevation when raising holder structure, the situation of sleeve pipe transport need be dismantled.
