Abstract
An indoor multifunctional penetrating type current transformer is composed of a high-voltage primary winding, a low-voltage secondary winding, an insulation protection body, a secondary coil fixing device, a secondary wiring cover box and an installation base board. The insulation protection body is formed by pouring indoor epoxy resin under a vacuum condition. A circular flange is respectively arranged at the head end and the tail end of the interior high-voltage primary winding, the flanges are fixed with external T-shaped wiring terminals through bolts so as to achieve flat board type installation mode and vertical board type installation mode, and the high-voltage primary winding is made by circular copper tubes. The secondary coil fixing device and the low-voltage secondary winding are fixed together, four positioning screws are arranged on the secondary coil fixing device to adjust and fix positions of the low-voltage secondary winding. The positioning screws are connected with foot inserts, and the installation base board is fixed with products through the foot inserts, thereby facilitating installation of products.
Description
Technical field
The utility model belongs to the penetration type high voltage power transformation equipment in the indoor special electric power system, is the crucial signal transmission equipment of 10kV and following electric power system electric energy metrical and relaying protection.
Background technology
At present, common penetration type current transformer primary connection terminal is single outlet method, or flat binding post, or the vertical plate type binding post, causes and can not install flexibly; And when the rated primary current value was bigger, one time winding adopted the solid copper conducting rod to manufacture usually, can not well prevent kelvin effect, and current ratio is more concentrated, and caloric value is bigger, caused the product electric property stable inadequately.
Summary of the invention
In order to overcome the deficiency that existing common penetration type current transformer primary connection terminal can not be installed flexibly and great current mutual inductor generates heat easily; The utility model provides a kind of indoor Mobyneb penetration type current transformer; Can realize flat and two kinds of mounting meanss of vertical plate type, and during the product operation, no matter the size of rated primary current value; The equal caloric value of the utility model is low, and electric property is reliable and stable.
The utility model solves the technical scheme that its technical problem adopted: it is made up of winding of high pressure, low pressure secondary winding, insulating protector, secondary coil fixture, secondary connection cover box, installation base plate six major parts.Head, end at a winding of high pressure respectively are provided with a circular flange, and flange surface is drilled with two pairs of four M12 screwed holes, join a T shape binding post outward; Be drilled with two pairs four Φ 13 holes with the flange surface position consistency on the round table surface of T shape binding post; Flange face and round table surface match, and contact-making surface evenly is coated with one deck conductive paste, install with becoming vertical plate type after the bolt; Become flat installation after removing, can use flexibly; When rated primary current was bigger in addition, winding of high pressure adopted the copper pipe manufacturing, and copper pipe is circular, and the centre is a hollow-core construction, has both reduced kelvin effect, has increased radius of curvature again, and the caloric value of product is low, and field intensity evenly distributes; In addition the indoor design of device body a kind of secondary pitch of the laps fixture; It and low pressure secondary winding are fixed together, and 4 positioning screws are arranged, with adjustment and fixing low pressure secondary winding on the secondary coil fixture; Guarantee that the electric force lines distribution between product internal high pressure and the low pressure is reasonable; Make the withstand voltage level of product high, local discharging level is low, and electric property is stable.
For secondary is concentrated cabling; The secondary lead wires of low pressure secondary winding is concentrated and is drawn out in the secondary connection cover box; The positioning screw links to each other with the footing inserts on the secondary coil fixture, base plate is installed is fixed together through footing inserts and product, base plate is installed is convenient to the product installation.
The beneficial effect of the utility model is, can realize dull and stereotyped and two kinds of mounting meanss of riser, selects use for the user; In addition, during the product long-time running, caloric value is low; Long-time running can not cause ageing of insulation; Electric property is stable, can accomplish that local discharging level is less than 5pC under 1.2Um/ √ 3 test voltages.
