Abstract

The utility model discloses a 750kV high-altitude large-cross-section wire combination type T-shaped wire clamp which is used for connecting a flexible bus with the device terminal in a transformer station that adopts the double bundle large-cross-section flexible wire as bus and branched lead for the 750kV power system at the high-altitude area. The 750kV high-altitude large-cross-section wire combination type T-shaped wire clamp is composed of a wire clamp body with a standard interface, and a drainage bracket which is connected and matched with the wire clamp body through a standard interface on the wire clamp body. The wire clamp body supports the wire and current is introduced from the wire. Through equipping different drainage brackets for matching with the device terminal, the effective supporting to the wire and the introducing of current are completed simultaneously. The reconnection of the broken wire is prevented when the wire is connected with the device terminal. The potential trouble of multifunction is reduced and the reliability of safe operation is increased. The product versatility is increased and is more suitable for mass production. The 750kV high-altitude large-cross-section wire combination type T-shaped wire clamp furthermore has the advantages of simple and rational structure, stable and reliable performance, convenient construction and maintenance, high economic property and practicality, beautiful appearance, and suitability for being generalized and applied.

Description

The high height above sea level large-section lead of 750kV combination type T molded lines folder
Technical field:
The utility model relates to the T molded lines folder that a kind of transformer station uses.Particularly relate to a kind of soft bus in the transformer station of electric power system 750kV high altitude localities is connected use with arrangement terminal T molded lines folder that is applied to.
Background technology:
In the high height above sea level of China 750kV transformer station, the T molded lines presss from both sides a this respect bears effective support to lead, again electric current is introduced the converting equipment from bus simultaneously, promptly bears the task that the lead-in wire of passing by on one's way is connected with equipment.But since different converting equipment with pass by on one's way lead pitch from not waiting, can't from main bus bar, electric current be transitted directly on the required connection device.Therefore, can only take main bus bar is disconnected, utilize two device clamps with bus respectively crimping fix, and then the terminal board of two device clamps be connected with the equipment end daughter board realize the broken string reclosing.By the equipment end daughter board electric current is introduced in the converting equipment.So, main bus bar forms two splicing points after disconnecting at least, has not only increased the hidden failure point, and has increased the workload of construction, maintenance and maintenance.The overall weight of splicing point is very big, will reduce the reliability of equipment again; And between when construction also will be to different equipment, carry out repeatedly unwrapping wire, because lead is shorter relatively, the property aesthetic in appearance of two leads was also relatively poor when unwrapping wire was uneven.
Summary of the invention:
Order of the present utility model provides the high height above sea level large-section lead of a kind of 750kV combination type T molded lines folder, mainly be to solve the lead-in wire of passing by on one's way in the existing high height above sea level transformer station to be connected can not be directly going between upward current transition to all converting equipments of existing with equipment from main, taking to break has not only increased the hidden failure point after the reclosing, construction, maintenance and the workload of safeguarding, and the reliability of reduction equipment.Inconvenience construction, influence problem attractive in appearance.
Scheme of the present utility model is as described below: this utility model comprises chuck and connecting plate, and it is the wire clamp main body that is provided with standard interface by, and a drainage stent formation supporting with it of the connection of the standard interface on the warp clip main body.Its wire clamp main body two ends are standard cartridge, form one by connecting plate between two chucks, are provided with standard interface on connecting plate.Its drainage stent can be hollow quadrilateral frame or the board-like framework of T shape.Its standard interface is one group of corresponding connecting hole.
The utility model compared with prior art has the following advantages and good effect: combine with the wire clamp main body by the drainage stent that adopts different structure, introduce electric current by the wire clamp main body from lead, be complementary through drainage stent and arrangement terminal again, can form the introducing of effective support and electric current lead.Broken string reclosing when not only effectively avoiding lead to be connected with arrangement terminal reduces potential faults, improves the safe operation reliability.Strengthened the versatility of product simultaneously, be more suitable for producing in batches.Have also that simple and reasonable, stable and reliable for performance, convenient construction, easy access are safeguarded, not only economy but also practicality, handsome in appearance generous, advantage such as be fit to apply.
Description of drawings:
Fig. 1 is the high height above sea level large-section lead of 750kV combination type T molded lines clamping structure figure;
Fig. 2 is the high height above sea level large-section lead of 750kV combination type T molded lines clamping structure figure.
Embodiment:
Fig. 1, the high height above sea level large-section lead of 750kV combination type T molded lines shown in Figure 2 press from both sides, its wire clamp main body is a universal accessories, wire clamp main body two ends are standard cartridge 1, be connected to form one by connecting plate 2 between two chucks 1, on connecting plate 2, be provided with standard interface 3, connect the drainage stent 4 by hollow quadrilateral frame or T shape board-like framework formed supporting by standard interface 3 and combine with it.This combination type T molded lines folder is held to hang to form effectively to lead by the wire clamp main body and is supported, and the drainage stent 4 that connects by standard interface 3 is connected with the equipment end daughter board, thereby avoid the broken string reclosing when electric current is introduced arrangement terminal or the broken string reclosing of redesign special equipment lead and arrangement terminal, to adapt to various multi-form equipment interfaces, make product versatility.Reduce potential faults, improved the safe operation reliability.Be more convenient for construction, maintenance and maintenance.
