[0030] In the related art, the installation tooling of the circuit breaker is an important part of the assembly equipment of the gas insulated metal enclosed switchgear (GIS), and the gas insulated metal enclosed switchgear is a metal enclosed switchgear and control equipment which at least a part of which uses a gas higher than atmospheric pressure as an insulating medium. GIS (GAS INSULATED SWITCHGEAR) is the English abbreviation of gas insulated fully enclosed combined electric appliance. GIS is composed of circuit breakers, disconnectors, grounding switches, transformers, arresters, busbars, connecting pieces and outgoing terminal, etc. These devices or components are all enclosed in a metal grounded shell, and a certain pressure of SF6 insulating gas is filled in the interior, so it is also called SF6 fully enclosed combined electric appliance.

[0031] Referring toFigure 4 In gas-insulated metal-enclosed switchgear, the contacts of the circuit breaker are threadedly connected to the conductor. During assembly, the threaded contacts and conductors need to be tightened to ensure the stable performance of the GIS circuit breaker, the safety of the circuit breaker's opening and closing, and the safe and reliable operation of the GIS equipment.

[0032] Fastening threaded contacts and conductors requires specialized installation fixtures. Related technologies employ fixtures with numerous components, complex structures, heavy weight, and high procurement costs. Therefore, this invention proposes an installation fixture with fewer components, flexible use, lightweight construction, and that saves time and effort.

[0033] The following reference Figures 1 to 3 The installation fixture proposed in this utility model will be described in detail.

[0034] Reference Figure 1 The installation fixture proposed in this embodiment of the utility model includes a fastening bracket 100 and two bolts 200. The fastening bracket 100 has a body portion 110, a first connecting portion 120 and a second connecting portion 130. The first connecting portion 120 and the second connecting portion 130 are connected to the body portion 110. The first connecting portion 120 and the second connecting portion 130 are respectively disposed at both ends of the body portion 110, so that the body portion 110, the first connecting portion 120 and the second connecting portion 130 enclose a clearance space 150. When the fastening bracket 100 is disposed along the circumference of the contact 10, the clearance space 150 can avoid the contact 10. The ends of the first connecting portion 120 and the second connecting portion 130 away from the body portion 110 are both provided with threaded holes 160.

[0035] Two bolts 200 are threaded into corresponding threaded holes 160. The bolts 200 abut against the contact 10 to fix the fastening bracket 100 to the contact 10. The fastening bracket 100 is provided with a mating part 140. In this embodiment, the mating part 140 is located in the middle of the body part 110. The mating part 140 is used to engage with a wrench so that the wrench drives the fastening bracket 100 to rotate, thereby driving the contact 10 to rotate, thus fastening the threaded contact 10 and conductor 20. After the contact 10 and conductor 20 are fastened, the bolts 200 are loosened, and the fastening bracket 100 can be removed from the contact 10.

[0036] When it is necessary to disassemble the contact 10 and the conductor 20, the mounting fixture is assembled onto the contact 10, and the fastening bracket 200 is rotated in the opposite direction by driving the wrench, so as to loosen the threaded connection between the contact 10 and the conductor 20.

[0037] Reference Figure 1 , Figure 2 , Figure 3In the embodiment, the body part 110, the first connecting part 120 and the second connecting part 130 are in an integrated structure, and the body part 110, the first connecting part 120 and the second connecting part 130 combine to form a circular arc structure which is adapted to the cross-sectional shape of the contact 10, thereby avoiding interference between the fastening frame 100 and the adjacent contact 10 when the fastening frame 100 rotates with the contact 10 when the assembly space is small.

[0038] In summary, the mounting tool has simple structure, few components, convenient assembly, flexible and portable use, time and labor saving, shortened GIS installation period, improved GIS assembly efficiency, improved GIS use reliability, and reduced processing cost due to few components.
