Integrated intelligent combination box-type substation

Abstract

The invention discloses an integrated intelligent combination box-type substation. The substation comprises a fuse combination cabinet, and a tripping interlock is arranged between a mechanism area and a triangular fuse tube area of the fuse combination cabinet; the triangular fuse tube area is provided with a door plank, and a mechanical interlock is arranged between the mechanism area and the door plank; a grounding system for a fuse tube is arranged inside the triangular fuse tube area; the bottom of a shell of the fuse combination cabinet is a shell bottom layer, and the shell bottom layeris a double-layer plate; the fuse combination cabinet is located inside a substation outer box, a transformer is arranged below the fuse combination cabinet, a cable connection box is arranged at theleft side of the fuse combination cabinet, and a low-voltage cabinet is arranged at the right side of the fuse combination cabinet; and the fuse combination cabinet and the transformer are connectedthrough a plurality of E-shaped connectors. The substation has the advantages of effective waterproofness, high safety, effective grounding, effective relief and effective connection.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an integrated intelligent combined box-type substation. Background technique [0002] The tripping linkage between the fuse box mechanism and the end cover of the fuse box becomes difficult when the mechanism and the fuse box are arranged left and right. The position of the end cap of the fuse cartridge is arranged in a square shape, and there is a height difference in height, which makes the tripping transmission troublesome. The tripping position of the existing fuse combination cabinet mechanism is far away from the air box surface of the inflatable cabinet, while the ejector rod of the end cover of the fuse cylinder is relatively close to the air box surface of the inflatable cabinet, there is a height difference, and the ejector rod is transmitted to the tripping position of the mechanism. Difficult location. The existing outdoor high-voltage fuse combination cabinet cann...

AI Technical Summary

Problems solved by technology

When the switch of the existing outdoor high-voltage fuse combination cabinet is grounded, the three-position load switch is grounded, and the grounding of the load switch makes the upper pile head of the fuse cylinder grounded, and at the same time, the main shaft connecting rod of the load switch pulls a separate grounding knife to fuse The lower pile head of the barrel is grounded. During the transmission process, the pull rod is easily deformed, which will cause the separate grounding knife to not fit in place.

[0004] The existing cable junction box adopts the traditional pressure relief channel, which has a single structure and cannot meet the demand for rapid pressure relief in a short time

At the same time, the traditional pressure relief channel does not have waterproof function and is limited to indoor use, which cannot meet the needs of outdoor use

When the bushings of existing outdoor transformers and high-voltage fuse combination cabinets are not aligned, or when the distance is relatively small, the cables used are too hard, which will easily cause stress on the cable accessories and cause poor contact at the cable connection for a long time.

Although the rainproof cover of the connecting piece of the existing outdoor transformer and high-voltage fuse combination cabinet is rainproof, the gap is too large, and the gap is not anti-mouse. Discharge to the casing, causing single-phase or three-phase grounding accidents in the high-voltage system
