Abstract
The cable lead in the transformer substation is connected with the secondary lead of the current transformer so as to provide current for relay protection equipment and metering equipment in the control room. When in connection, the cable lead penetrates into the secondary junction box of the current transformer through the cable penetrating hole and is connected with the binding post of the secondary lead of the current transformer, and then the secondary junction box cover is installed. If the secondary junction box of the current transformer is of a non-sealing structure, moisture easily enters the secondary junction box of the current transformer, so that insulation resistance between the secondary leads is reduced and lower than a national standard required value, and normal operation of products is affected. The utility model provides a secondary junction box structure of a current transformer, which comprises a secondary junction box, hanging lugs, bolts, rectangular sealing gaskets and a secondary junction box cover, wherein the hanging lugs are respectively arranged on two sides of the secondary junction box, the rectangular sealing gaskets are arranged in the secondary junction box cover and are buckled on the secondary junction box and are fixed by the bolts. Reasonable design, good sealing, stable performance and reliable operation.
Description
Technical field:
the utility model relates to a current transformer, in particular to a secondary junction box structure of the current transformer.
The background technology is as follows:
the cable lead in the transformer substation is connected with the secondary lead of the current transformer so as to provide current for relay protection equipment and metering equipment in the control room.

Two sides of the secondary junction box are respectively provided with a hanging lug.
The hanging lugs are L-shaped, and two mounting holes are respectively formed in the two faces.
A sealing gasket is arranged in the secondary junction box cover, and the sealing gasket is a rectangular sealing gasket.
The secondary junction box cover is fixed with the hanging lugs of the secondary junction box through bolts.
The secondary junction box structure of the current transformer has the following advantages:
1. the hangers are L-shaped, and the two sides of the hangers are respectively provided with mounting holes matched with the secondary junction box and the secondary junction box cover, so that the hangers are wide in application range, can be used for production in factories and factories, and can be suitable for maintenance and transformation of current transformers in substations.
2. The secondary junction box and the secondary junction cover are connected by the sealing gasket, so that the waterproof and dampproof effects can be achieved effectively, and the insulation resistance between the secondary leads is improved.
Description of the drawings:
fig. 1 is a schematic structural diagram of an embodiment of a secondary junction box structure of a current transformer according to the present utility model, which includes a secondary junction box 1, a hanger 2, a bolt 3, a bolt 4, a rectangular gasket 5, and a secondary junction box cover 6.
The specific embodiment is as follows:
one embodiment of the utility model is shown in figure 1 and comprises a secondary junction box 1, a hanging lug 2, a bolt 3, a bolt 4, a rectangular sealing gasket 5 and a secondary junction box cover 6;
wherein two hangers 2 are respectively arranged at two sides of the secondary junction box 1, and the hangers 2 and the secondary junction box 1 are fixed by bolts 3.
The rectangular sealing gasket 5 is arranged at the boss position of the secondary junction box cover 6.
The secondary junction box cover 6 with the rectangular sealing gasket 5 is buckled on the secondary junction box 1, and the secondary junction box cover 6 is fastened with the lugs 2 on two sides of the secondary junction box 1 by bolts 4.
