Abstract
The utility model belongs to power system security Work tool field, be specifically related to a kind of combined high-voltage three-phase shortcircuit earth connection, be made up of short-circuit line (1), earth connection (2), tap (3), described short-circuit line is connected by tap with earth connection.Combined high-voltage three-phase shortcircuit earth connection separates short-circuit line with earth connection, do not affect the function of short-circuit grounding wire, change and be fixedly connected as separate type, make its short-circuit line that can connect different length and earth connection, be convenient to replace fault electric wire simultaneously, increased now flexibility in use of short circuit grounding.
Description
Technical field
The utility model belongs to power system security Work tool field, is specifically related to a kind of combined high-voltage three-phase shortcircuit earth connection.
Background technology
Existing high pressure three-phase shortcircuit termination, mostly adopts the common copper pipe of crimping to realize being connected between short-circuit line and earth connection, after such crimping, the length of short-circuit line and earth connection and between connected mode fix, be difficult to change and replacement.But in practical operation.Three-phase electricity in electric power system be subject to safe distance, the impact of the factor such as installing space, its span is uncertain.In the time using high pressure three-phase shortcircuit earth connection, certain phase span will be remaining compared with hour short-circuit line or earth connection like this, causes electric wire waste; Otherwise if the connection of short-circuit line or earth connection will be comparatively nervous when certain phase span is larger, electric wire is for a long time in tensioning state, it is insecure that the tie point on it will become, thereby cause electric power system fault.Meanwhile, the high pressure three-phase shortcircuit earth connection of this fixed connection is also very inconvenient in the time of access, and four lines are intertwined and are difficult for arranging.
Utility model content
The purpose of this utility model is to provide a kind of Modular high pressure three-phase shortcircuit earth connection, have easy to use, simple to operate, the feature that is easy to deposit.
The utility model is made up of short-circuit line, earth connection, tap, and wherein there are three binding posts tap one end, and the other end has a binding post; Short-circuit line and earth connection one end are equipped with connection plug, and short-circuit line is connected by the binding post that connection plug is inserted on tap with earth connection.
The utility model adopts modular construction, short-circuit line is separated with earth connection, do not affect the function of high pressure three-phase shortcircuit earth connection, change and be fixedly connected as separate type, so in use, according to the needs of field apparatus, can rapid-assembling become the short-circuit grounding wire of different length, just there will not be because of span problem, cause electric wire waste or tie point loosening; If in use short-circuit grounding wire breaks down, only replace fault electric wire, can not cause scrapping of whole group of short-circuit grounding wire; Every short-circuit line and earth connection can be wound around respectively, separate and deposit with tap.

Embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, embodiment of the present utility model is described in further detail.
As shown in the figure, the utility model combined high-voltage three-phase shortcircuit earth connection, is made up of short-circuit line 1, earth connection 2, tap 3, and short-circuit line 1 is equipped with connection plug 4 with earth connection 2 one end, tap 3 one end are provided with three short-circuit line binding posts 5, and the other end is provided with an earth connection binding post 6.
When use, three short-circuit lines 1 insert three short-circuit line binding posts 5 of tap 3 one end by the connection plug 4 on it, earth connection 2 inserts the earth connection binding post 6 of tap 3 other ends by connection plug on it 4, connection plug is inserted after the binding post on tap, rotation connection plug, make the projection 8 on connection plug snap in the radially draw-in groove 7 on binding post, so connection plug is just fixed on binding post, has formed combined high-voltage three-phase shortcircuit earth connection.
That the utility model is exemplarily described above; certainly the utility model specific implementation is not subject to the restrictions described above; in its shape or structure, do any variation no matter be; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
