Abstract
The utility model discloses a high-voltage potential transformer cabinet, which comprises a cabinet body. A fully-closed elbow seat type three-phase potential transformer with a fuse is mounted in the cabinet body and obtains high-voltage power from a three-phase high-voltage bus connection socket mounted in a high-voltage chamber of the cabinet body, the bus connection socket is provided with a rod-shaped conductor, excepting a connection end, part of the conductor is sealed in an insulation outer casing made of epoxy resin materials by compression molding, an outer end of the insulation outer casing is mounted on the cabinet body through screws, an annular groove for being jointed with a bus connector is arranged on the periphery of the conductor and at the outer end of the insulation outer casing, a conical connecting face jointed with a cable shoe of a cable is arranged on the outer side of the inner end, at the conductor, of the insulation outer casing, and the cable shoe of the cable is tightly sleeved to the conical connecting face to isolate a high-voltage charged body from the outside. Compared with the prior art, the high-voltage potential transformer cabinet solves the problem that an existing high-voltage potential transformer cabinet is oversized.
Description
Technical field
The utility model relates to power equipment manufacturing technology field, especially a kind of voltage transformer equipment that is used for the ring network power supply system.
Background technology
The high voltage potential transformer cabinet is contained on the bus of electric power system, to detect busbar voltage and to be that the protected location equipment of high-voltage electrical equipment provides signal to realize defencive function.Using more high voltage potential transformer cabinet at present in the ring main unit electric power system is the threephase potential transformer that monitoring and sampling action are housed in cabinet, this threephase potential transformer is obtained high voltage source by exposed conducting line row from the bus connection seat that is contained on the cabinet, the voltage transformer primary line is in series with high-tension fuse in the loop, high-tension fuse exposes in air, the connection of this primary line is to be dielectric with the air, require bigger to insulation spacing alternate and relatively, the bigger installing space of needs under the situation that satisfies the air insulation spacing, the volume of whole cabinet is bigger, is not suitable for the requirement of the miniaturization Design of electric equipment.
Summary of the invention
Problem to be solved in the utility model provides a kind of high voltage potential transformer cabinet, and it can solve the long-pending excessive problem of existing high voltage potential transformer cabinet.
In order to address the above problem, the technical solution adopted in the utility model is: this high voltage potential transformer cabinet, include cabinet and be contained in the interior totally-enclosed elbow headstock formula band fuse threephase potential transformer of this cabinet, and be contained in three bus connection seats on the described cabinet, described totally-enclosed elbow headstock formula band fuse threephase potential transformer joins by cable and described three the bus connection seats that three links have a cable shoes respectively, is built-in with high-tension fuse at described totally-enclosed elbow headstock formula band fuse threephase potential transformer; Described bus connection seat has a bar-shaped electric conductor, this electric conductor partially enclosed in the insulation crust that is formed by the epoxide resin material pressure injection except that connecting the termination; The outer end of described insulation crust is contained on the described cabinet by screw, and the outer end of described insulation crust has one and is used for the annular groove that engages with bus tie around described electric conductor; Described insulation crust has a taper connection face that engages with the cable shoes of described cable outside the inner of described electric conductor, the cable shoes of described cable closely is enclosed within on this taper connection face high-voltage charged body is isolated with the external world.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
Owing to adopt cable to be connected between three bus connection seats and the totally-enclosed elbow headstock of the high pressure formula band fuse threephase potential transformer with cable shoes, and make this cable and totally-enclosed elbow headstock formula band fuse threephase potential transformer, make joint and extraneous sealing between this cable and the bus connection seat, make the high-voltage charged body and the extraneous solid material isolated insulation that obtains of high voltage potential transformer cabinet primary line, alternate dielectric strength is increased, phase spacing can obtain to dwindle, thereby can produce the high voltage potential transformer cabinet of small size, high voltage potential transformer cabinet with the 12kV voltage specification is an example, this high voltage potential transformer cabinet only for existing high voltage potential transformer cabinet long-pending 3/5.
