Abstract
The utility model relates to a novel guide rod type sleeving pressure equalizing ball mounting structure and belongs to the technical field of transformer equipment. The technical scheme is that the novel guide rod type sleeving pressure equalizing ball mounting structure comprises a pressure equalizing ball (1), a fixed plate (2), a fastener I (3), a fastener II (4) and a fastener III (5); wherein the pressure equalizing ball (1) is provided with an internal thread structure; the fixed plate (2) is provided with an external thread structure matched with the internal thread structure; a mounting hole is formed in the fixed plate (2); the fixed plate (2), the fastener I (3), the fastener II (4) and the fastener III (5) are fixedly arranged on a sleeving (6) by the mounting hole; the pressure equalizing ball (1) and the fixed plate (2) are mutually connected by the internal thread structure and the external thread structure. The novel guide rod type sleeving pressure equalizing ball mounting structure has the beneficial effects that the structures of the pressure equalizing ball with built-in internal threads and the fixed plate with external threads are adopted, the fixed plate and the sleeving are mutually fixed, the size of the original sleeving is kept, and the problem of connection difficulty of a detachable wire is solved.
Description
Technical field
The utility model relates to a kind of Novel guide rod type sleeve pipe voltage equalizing ball mounting structure, belongs to transformer equipment technical field.
Background technology
Be greater than in the 220kV generator main design of transformer of 720MVA at capacity, high-voltage connection adopts detachable lead-in wire conventionally, in the time that bushing is selected Japanese NGK guide rod type sleeve pipe, it can not meet installation requirement with the detachable voltage equalizing ball being connected that goes between, because it is large that detachable lead-in wire takes up room, without operating space.
Utility model content
The utility model object is to provide a kind of Novel guide rod type sleeve pipe voltage equalizing ball mounting structure, design Novel voltage equalizing ball, its Outside Dimensions is identical with former voltage equalizing ball, by the employing of internal and external threads structure, can, easily by voltage equalizing ball installation and removal, solve the problems referred to above that exist in background technology.
The technical solution of the utility model is: a kind of Novel guide rod type sleeve pipe voltage equalizing ball mounting structure, comprise voltage equalizing ball, fixed head, securing member one, securing member two and securing member three, described voltage equalizing ball is provided with female thread structure, fixed head is the external thread structure matching with it, fixed head is provided with installing hole, fixed head is fixedly installed on sleeve pipe by installing hole and securing member one, securing member two, securing member three, and voltage equalizing ball and fixed head are connected to each other by female thread structure and external thread structure.
The material of described voltage equalizing ball is cast aluminium alloy.
On described fixed head, the size of installing hole and the size of sleeve pipe match.
The beneficial effects of the utility model are: adopt the voltage equalizing ball of built-in internal thread, structure with externally threaded fixed head, fix by fixed head and sleeve pipe, this structure had both kept former casing size, have solved again with detachable lead-in wire and have been connected difficult problem.

Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of Novel guide rod type sleeve pipe voltage equalizing ball mounting structure, comprise voltage equalizing ball 1, fixed head 2, securing member 1, securing member 24 and securing member 35, described voltage equalizing ball 1 is provided with female thread structure, the external thread structure of fixed head 2 for matching with it, fixed head 2 is provided with installing hole, fixed head 2 is fixedly installed on sleeve pipe 6 by installing hole and securing member 1, securing member 24, securing member 35, and voltage equalizing ball 1 is connected to each other by female thread structure and external thread structure with fixed head 2.
The material of described voltage equalizing ball 1 is cast aluminium alloy.
On described fixed head 2, the size of installing hole and the size of sleeve pipe 6 match.
In use, extract the former voltage equalizing ball of sleeve pipe, design Novel voltage equalizing ball 1, material is cast aluminium alloy, voltage equalizing ball 1 inside is tapped special construction; Design fixed head 2, this fixed head is external thread structure, and screw thread matches with the screw thread of voltage equalizing ball 1, and the installing hole on fixed head 2 and former sleeve pipe match; When assembling, first the former voltage equalizing ball securing member of fixed head 2 use is fixed on sleeve pipe, voltage equalizing ball 1 is fastening with screw thread rotation mode and fixed head 2 and sleeve pipe 6, in the time that sleeve pipe 6 is connected with transformer detachable lead-in wire, voltage equalizing ball 1 is fallen after rise to detachable lead-in wire correct position (exposing terminal block), after sleeve pipe 6 and lead-in wire connect, then voltage equalizing ball 1 is reassembled to original position.
