Abstract
The utility model discloses a tank type voltage transformer, which comprises an outer casing. A body is arranged inside the outer casing; a disc insulator is arranged on the upper portion of the outer casing and electrically connected with the body; the disc insulator is electrically connected with the body through a spring connecting part made of a conductor; and a shield is arranged on an outer cover of the spring connecting part. The voltage transformer adopts the technical scheme, and a connecting lead connected between the disc insulator and the body is replaced by the connection spring made of the conductor, thereby not only simplifying assembly of the voltage transformer, but also being capable of automatically adjusting length by elasticity of the spring in assembly as the connection spring has an automatic expansion function, leading the spring to be completely protected by the shield, increasing use reliability of the voltage transformer, and increasing production quality of the voltage transformer.
Description
Technical field
The utility model relates to a kind of pot type voltage transformer.
Background technology
Voltage transformer is a kind of output equipment that is used for electric energy metrical and relaying protection voltage signal in the electric power system; existing voltage transformer as shown in Figure 1 and Figure 2; it comprises a shell 1; be provided with device body 2 in the shell 1; shell 1 top is provided with disc insulator 3; need by being connected lead 5 conductings between disc insulator 3 and the device body 2, on disc insulator 3, also be provided with and be used to shield the shielded-plate tube 4 that connects lead 5, leave the gap between shielded-plate tube 4 and the device body 2.This voltage transformer is in when assembling, and an end that will connect lead 5 earlier is connected on the device body 2, and then the other end that will connect lead 5 is connected on the disc insulator 3, and disc insulator 3 is installed at last.For the ease of when assembling, connecting fixing between lead 5 and the disc insulator 3, the length that connects lead 5 is reserved with certain surplus, thereby causing instrument transformer to connect lead 5 unnecessary parts after assembling finishes exposes outside the shielded-plate tube 4 in the gap between shielded-plate tube 4 and device body 2 easily, cause shielded-plate tube 4 can not shield this connection lead 5, reduced the security reliability of voltage transformer, cause voltage transformer in use to break down easily, influence the normal operation of power supply system.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of easy to assembly, safe and reliable pot type voltage transformer is provided.
The technical solution of the utility model is: a kind of pot type voltage transformer, comprise shell, and be provided with the device body in the shell, shell upper is provided with disc insulator, be electrically connected by conductor between disc insulator and the device body, be covered with radome outside conductor, described conductor is a spring fastenings.
Described spring fastenings is the beryllium-bronze cylindrical spring.
Voltage transformer of the present utility model adopts technique scheme; it is replaced by the connection lead that is connected between disc insulator and the device body on the connection spring of being made by conductor; it has not only simplified the assembling of voltage transformer; and because the connection spring has flexible automatically function; it utilizes the elasticity of spring can regulate length automatically in assembling; spring is among the protection of radome fully, has increased the security reliability of voltage transformer, improved the quality of production of voltage transformer.
Description of drawings
Fig. 1 is the structural representation of existing voltage transformer;
Fig. 2 is the A portion enlarged drawing among Fig. 1;
Fig. 3 is a structural representation of the present utility model.
Embodiment
As shown in Figure 3, voltage transformer of the present utility model comprises shell 1, device body 2, disc insulator 3 and shielded-plate tube 4, one end of shielded-plate tube 4 is fixed on the disc insulator 3, the other end extends near device body 2 towards device body 2, leave the gap between shielded-plate tube 4 and the device body 2, be coated with a cylindrical spring 6 of being made by beryllium-bronze in shielded-plate tube 4, the two ends of cylindrical spring 6 fixedly are electrically connected with disc insulator 3 and device body 2 respectively.Device body 2 comprises coil windings, and coil windings is provided with radome outward, and an end of cylindrical spring 6 is connected electrically on this radome.
