Embodiment 1

[0030] An improved sulfur hexafluoride circuit breaker, such as Figure 1~4 As shown, it includes housing 1, mounting bracket 2, wing plate 3, fixing bolt 4, outlet porcelain sleeve 5, lower equalizing ring 6, mounting base 7, connecting plate 8, upper equalizing ring 9, terminal 10, Tank body 11, lifting arm 12, adjusting handle 13, arc extinguishing chamber 14, static contact 15, door body 16, lockset 17, wherein, a number of mounting frames 2 are fixedly connected to the top of the housing 1, and on the mounting frame 2 There are wing plates 3 at both ends of the wing plate 3, fixed bolts 4 are arranged on the wing plate 3, the outlet porcelain sleeve 5 is fixedly connected to the mounting frame 2, and the lower pressure equalizing ring 6 is arranged at the bottom end of the outlet porcelain sleeve 5, There is a mounting seat 7 on the top of the outlet porcelain bushing 5, a connecting plate 8 is connected between adjacent mounting seats 7, an upper pressure equalizing ring...

Embodiment 2

[0033] An improved sulfur hexafluoride circuit breaker, such as Figure 1~4 As shown, it includes housing 1, mounting bracket 2, wing plate 3, fixing bolt 4, outlet porcelain sleeve 5, lower equalizing ring 6, mounting base 7, connecting plate 8, upper equalizing ring 9, terminal 10, Tank body 11, lifting arm 12, adjusting handle 13, arc extinguishing chamber 14, static contact 15, door body 16, lockset 17, wherein, a number of mounting frames 2 are fixedly connected to the top of the housing 1, and on the mounting frame 2 There are wing plates 3 at both ends of the wing plate 3, fixed bolts 4 are arranged on the wing plate 3, the outlet porcelain sleeve 5 is fixedly connected to the mounting frame 2, and the lower pressure equalizing ring 6 is arranged at the bottom end of the outlet porcelain sleeve 5, There is a mounting seat 7 on the top of the outlet porcelain bushing 5, a connecting plate 8 is connected between adjacent mounting seats 7, an upper pressure equalizing ring...

Embodiment 3

[0035]On the basis of Embodiment 2, Embodiment 3 is further shown in the figure, and the grip position of the adjustment handle is covered with a rubber anti-slip sleeve. The rubber non-slip sleeve makes the hand grip process more reliable and labor-saving; figure 2 As shown: the bottom of the door body 16 is uniformly arranged with three threading holes, and the walls of the threading holes are covered with rubber sleeves. The rubber sleeve can protect the cables coming out. Such as figure 1 , 3 , as shown in 4: the lifting arm includes two connecting rods hinged to each other. Such as figure 1 As shown: the connecting plate 8 is connected by a stud bolt at the top of the tank body 11 . The stud structure can adjust the height of the connecting plate; as shown in the figure: the handle of the adjustment handle 13 can be folded to be parallel to the direction of the door body surface and then stored, and the handle is fully opened and perpendicular to the direction of th...

Abstract

The invention provides an improved sulfur hexafluoride circuit breaker. According to the technical scheme, on the premise that the principle of the circuit breaker is not changed, the installation structure of the circuit breaker is innovatively improved. Specifically, a shell with a cavity is used as a basic bearing structure, wing plates are arranged on the shell, and the circuit breaker can be rapidly installed and fixed through fixing bolts; on the basis, the outgoing line porcelain sleeve is carried on the mounting rack, and the upper end and the lower end of the outgoing line porcelain sleeve are respectively provided with a grading ring. The wiring terminal is arranged on the movable mounting seat, and the mounting seat is carried on the lifting arm, so that the height of the wiring terminal can be adjusted within a certain range when the lifting arm is controlled to ascend and descend by using the adjusting handle, and different wiring requirements are met. Besides, the door body is arranged at the tail end of the cavity of the shell, internal electrical elements can be protected, meanwhile, the door body can be locked, and therefore internal safety is guaranteed. The circuit breaker is reasonable in structure and good in using effect.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an improved sulfur hexafluoride circuit breaker. Background technique [0002] Sulfur hexafluoride circuit breaker is a circuit breaker that uses sulfur hexafluoride gas as the arc extinguishing medium and insulating medium. Due to the excellent characteristics of sulfur hexafluoride gas, the single break of this circuit breaker is much higher than the compressed air circuit breaker and oil-less circuit breaker in terms of voltage and current parameters, and does not require high air pressure and a considerable number of series breaks. [0003] At present, sulfur hexafluoride circuit breakers are mainly divided into two types: porcelain column structure and tank structure. Among them, the porcelain column circuit breaker uses a hydraulic operating mechanism. The control and operating components and lines of the hydraulic mechanism are all located in the control cabinet...
