Abstract

The utility model relates to a terminal for a transformer, which is improved on the basis of the existing terminal structure. The terminal for a transformer comprises a conductive rod, screw nuts, a cushion ring, a sleeve pipe, beads of sealing gum, a sleeve pipe, and a sealing ring which are sheathed. The terminal for a transformer has the points that the lower part of the conductive rod is provided with a current measuring device composed of a porcelain seat, a positioning clamp, a positioning insulating pipe, a current transformer, and a magnetic shield plate to replace the existing lower porcelain sleeve, and the terminal for a transformer can directly measure the output current of the transformer from the internal part of the transformer. The terminal for a transformer has the advantages of novel design, simple structure, and convenient installation. The terminal for a transformer can replace the low-voltage terminal of the existing transformer and can effectively prevent the occurrence of the electricity stealing condition.

Description

Terminal for transformer

The utility model relates to the low tension terminal in all types of transformers.

The personnel that are engaged in the transformer research and design know, do not design power supply power department on the existing transformer device structure and measure the technical measures of electricity consumption metering, the measurement of transformer output electric weight is carried out at power distribution station, so just occurs the phenomenon of tax evasion electricity unavoidably, causes economic loss to country.Though power department is preventing to have adopted many precautionary measures on the tax evasion electricity, because the power supply net distributes extensively, administrative structure is many, finally is difficult to address the above problem.

The purpose of this utility model provides a kind of binding post of transformer, and it is to improve invention on the basis of the low tension terminal of existing transformer.Have novel in design, simple in structure; the function that not only has existing binding post; and be accuracy, reliability and a kind of suitable product that prevented from providing of phenomenon is provided of the output electric weight of measuring transformer, closely protecting for the big electric current of transformer provides reliable measurement.

Below in conjunction with accompanying drawing the binding post of a kind of transformer of the utility model is carried out detailed narration:

Accompanying drawing 1 is a structure cutaway view of the present utility model;

Accompanying drawing 2 is that the utility model is installed in the position view on the transformer.

With reference to the accompanying drawings 1,2, shown in, the binding post of a kind of transformer of the present utility model is that the architecture basics at existing binding post improves and forms. It comprises conducting rod (1), nut (2), packing ring (3), sleeve pipe (4), sealant bead (5) Sleeve pipe (6), sealing snare (7) forms, it improves the invention main points is to be provided with by porcelain seat (10) in the bottom of conducting rod (1), locator card (9), location insulation tube (12), current transformer (15), the current measuring device that magnetic shield panel (14) consists of, to replace existing insulator, current transformer (15) is arranged in the porcelain seat (10) and passes through locator card (9), location insulation tube (12) is fixed on the conducting rod (1), casting epoxy resin (11) around the current transformer (15), have logical oil groove (8) on the top of porcelain seat (10), the bottom connects magnetic shield panel (14), is provided with secondary line binding post (13) in magnetic screen (14).

The method that the utility model low tension terminal is installed and used as shown in Figure 2, measurement mechanism partly is installed in main body cover (16) reverse side of transformer, and binding post (13) connects lead and is connected with the measuring instrument of transformer outer setting by behind the main body cover (16). Like this, just can directly record the output current of transformer from the inside of transformer.

The utility model modern design, simple in structure, easy for installation, the low tension terminal that replaces existing transformer have fundamentally solved the problem of the electric current output metering device error of existing transformer, can prevent the generation of the situation of sneaking current effectively.

Claims

A kind of binding post of transformer, it comprises conducting rod (1), nut (2), packing ring (3), sleeve pipe (4), sealant bead (5), sleeve pipe (6), sealing snare (7) is formed, it is characterized in that being provided with by porcelain seat (10) in the bottom of conducting rod (1), locator card (9), location insulated tube (12), current transformer (15), the current measuring device that magnetic shield panel (14) constitutes, to replace existing insulator, current transformer (15) is arranged in the porcelain seat (10) and passes through locator card (9), location insulated tube (12) is fixed on the conducting rod (1), casting epoxy resin (11) around the current transformer (15), have logical oil groove (8) on the top of porcelain seat (10), the bottom connects magnetic shield panel (14), is provided with secondary line binding post (13) in magnetic screen (14).
