The utility model discloses a fixing device for a plurality of busses in high-voltage switch equipment, comprising a mounting bracket, a support insulator and a fixed clamp, wherein the mounting bracket is fixed at the top of the switch equipment, and can be a three phase-into-one phase structure for mounting a plurality of groups of buses, namely that the mounting bracket is formed by respectively connecting a plurality of single mounting brackets; the support insulator is arranged above the mounting bracket; the fixed fixture is arranged above the support insulator; the buses are fixed in the fixed clamp; the fixed fixture arranged in each support insulator is respectively composed of two single fixed clamps; the two single fixed clamps are arranged up and down, and the opened end thereof are arranged opposite to each other; and the fixed clamp, the support insulator and the mounting bracket are tightly fixed together through bolts. The utility model eliminates the limitation of the traditional insulating production processing technology, and enables the whole system to safely and reliably run.
Description
Technical field
The utility model relates to a kind of fixture of many busbars, especially relates to a kind of metal stationary installation that is used for many busbars in the high voltage switchgear.
Background technology
When the rated current of switchgear inner horizontal main bus bar meets or exceeds 2500A, (be commonly called as " high-current switch equipment "), adopt single busbar to be difficult to satisfy instructions for use, at this moment need to adopt busbar more than two or two as level master busbar.The problem of thereupon bringing is, adopts many busbars as level master busbar, how fixedly to be considerable problem, because should guarantee safely, reliable and attractive in appearance, also will consider the electric power that busbar was produced when the heat dissipation problem of busbar and system were short-circuited.Traditional mode of utilizing insulating sleeve and supporting insulator to fix because of being subjected to the restriction of insulated product processing technology, can not satisfy the user demand of high-current switch equipment far away, thereby has also restricted the use of high-current switch equipment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of fixture that is used for many busbars in the high voltage switchgear at problems of the prior art, its objective is many busbar safety in the high voltage switchgear, be fixed up reliably, satisfy actual user demand well.
The technical solution of the utility model is that this kind is used for that the fixture of many busbars comprises the mounting bracket that is fixed on the switchgear top in the high voltage switchgear, be positioned at the supporting insulator of mounting bracket top and the stationary fixture that is positioned at the supporting insulator top, many busbars are fixed in the stationary fixture.
Described mounting bracket is for installing the three-phase integratedization structure of many busbars of many groups simultaneously, that is, mounting bracket connects common the composition successively by a plurality of mounting bracket monomers.
The stationary fixture that is positioned on each supporting insulator all is made up of two stationary fixture monomers, and two stationary fixture monomers are arranged along direction one on the other, and the openend positioned opposite of two stationary fixture monomers.
Described stationary fixture monomer is to have a plurality of draw-in grooves that hold many busbars, and the two ends of stationary fixture monomer are respectively equipped with bolt hole, and by construction bolt two stationary fixture monomers is fixed together.
Described stationary fixture, supporting insulator and mounting bracket are fixed together closely by bolt.
A kind of fixture that is used for many busbars in the high voltage switchgear with above-mentioned special construction has the following advantages:
1, this kind is used for the fixture employing metal stationary installation of many busbars in the high voltage switchgear, broken away from the restriction of traditional insulated product processing technology, makes the operation of whole system more safe, reliable.
2, this kind is used for that the fixture of many busbars adopts three-phase integrated formula structure in the high voltage switchgear, makes entire bracket more firm, can satisfy the uses of many busbars of many groups simultaneously again.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left TV structure schematic diagram of structure shown in Figure 1.

In Fig. 1-4,1: mounting bracket; 2: supporting insulator; 3: many busbars; 4: stationary fixture; 5: set bolt.
Embodiment
By Fig. 1-4 combination as can be known, the fixture that this kind is used for many busbars in the high voltage switchgear comprises the mounting bracket 1 that is fixed on the switchgear top, mounting bracket 1 is the three-phase integratedization structure that many busbars of many groups can be installed simultaneously, promptly, mounting bracket 1 connects common the composition successively by a plurality of mounting bracket monomers, the stationary fixture 4 that is positioned at the supporting insulator 2 of mounting bracket 1 top and is positioned at supporting insulator 2 tops, many busbars 3 are fixed in the stationary fixture 4; The stationary fixture 4 that is positioned on each supporting insulator 2 all is made up of two stationary fixture monomers, two stationary fixture monomers are arranged along direction one on the other, and the openend positioned opposite of two stationary fixture monomers, the stationary fixture monomer is to have a plurality of draw-in grooves that hold many busbars, the two ends of stationary fixture monomer are respectively equipped with bolt hole, and by construction bolt 5 two stationary fixture monomers are fixed together.That is, stationary fixture 4 is divided into upper and lower two parts, and many busbars 3 are positioned in the stationary fixture 4, utilizes construction bolt 5 that busbar is fixed up firmly then.
At last, the stationary fixture 4 and supporting insulator 2, the mounting bracket 1 that fix are fixed on one closely by bolt.
The fixture that this kind is used for many busbars in the high voltage switchgear adopts the metal stationary installation, broken away from the restriction of traditional insulated product processing technology, make the operation of whole system more safe, reliable, simultaneously, adopt three-phase integrated formula structure, make entire bracket more firm, can satisfy the use of many busbars of many groups simultaneously again.
