Description

Technical Field

[0001] The utility model relates to the technical field of mechanism emergency inspection and repair, and in particular to a housing of a hydraulic spring operating mechanism of a high-voltage circuit breaker that can be inspected without removing the cover. Background Art

[0002] The hydraulic spring operating mechanism of a high-voltage circuit breaker is usually designed with a container plate structure, which is composed of modules that realize various functions. The appearance is generally designed to be cylindrical. The operating mechanism action process includes electrical control and mechanical action. The impact force of the mechanism is relatively large during the energy storage and pressure relief process. The operating mechanism shell serves to prevent debris from falling into the mechanism and causing electrical or mechanical damage and injury to personnel during the action process.

[0003] The current operating mechanism shell is a two-half structure, connected into a whole circle by a row of stainless steel bolts on each side. When the mechanism is inspected for faults or shut down for maintenance, all the stainless steel bolts need to be removed and then the shell is removed. This is very inconvenient when the circuit breaker mechanism is undergoing emergency fault inspections, and generally the circuit breaker cover is removed under pressure. During the removal process, maintenance personnel may accidentally touch the opening and closing coils and get injured, posing a certain safety risk. Utility Model Content

[0007] The housing comprises an annular outer shell and an annular inner shell, the annular outer shell and the annular inner shell are connected to each other in staggered layers, and the annular outer shell and the annular inner shell are arranged along the same axis;

[0008] One end of the annular outer shell close to the annular inner shell is detachably connected to one end of the annular inner shell close to the annular outer shell;

[0010] During maintenance, the operator grasps the first upper arc shell of the annular inner shell, so that the first upper arc shell slides axially along the second lower arc shell of the annular inner shell, so that the first upper arc shell is away from the annular outer shell of the shell body, so that the pressure is released before maintenance, avoiding accidental injury to the operator due to sudden pressure release of the circuit breaker energy storage spring during the cover removal process.

[0011] The present embodiment discloses a housing of a hydraulic spring operating mechanism of a high-voltage circuit breaker that can be inspected without removing the cover.

[0038] The housing 1 comprises an annular outer shell 2 and an annular inner shell 3, the annular outer shell 2 and the annular inner shell 3 are connected to each other in staggered layers, and the annular outer shell 2 and the annular inner shell 3 are arranged along the same axis;

[0039] One end of the annular outer shell 2 close to the annular inner shell 3 is detachably connected to one end of the annular inner shell 3 close to the annular outer shell 2;

[0040] The annular inner shell 3 has a first upper arc shell 4 and a second lower arc shell 5 . The two ends of the first upper arc shell 4 can be slidably adapted to the two ends of the second lower arc shell 5 . The first upper arc shell 4 is slidably fitted along the axial direction of the housing 1 .

[0041] During maintenance, the operator grasps the first upper arc shell 4 of the annular inner shell 3, so that the first upper arc shell 4 slides axially along the second lower arc shell 5 of the annular inner shell 3, so that the first upper arc shell 4 is away from the annular outer shell 2 of the shell body 1. In this way, pressure relief is performed before maintenance, so as to avoid accidental injury to the operator due to sudden pressure relief of the circuit breaker energy storage spring during the cover removal process.

[0042] The present embodiment discloses a housing of a hydraulic spring operating mechanism of a high-voltage circuit breaker that can be inspected without removing the cover. Since the annular outer shell 2 and the annular inner shell 3 are staggered with each other, the first upper arc-shaped shell 4 can slide. By opening and closing the first upper arc-shaped shell 4, the hydraulic spring operating mechanism of the high-voltage circuit breaker is easy to inspect. As a result, the housing of the hydraulic spring operating mechanism of the high-voltage circuit breaker that can be inspected without removing the cover has the beneficial effects of convenient emergency maintenance, not being easy to touch the opening and closing coils to cause injuries, and having low safety risks.

The plurality of lock buckles 8 can fix the first upper arc-shaped shell 4 on the annular shell 2. When no inspection is required, the use of a plurality of lock buckles 8 for fixing can prevent the first upper arc-shaped shell 4 from sliding left and right during normal operation or action of the circuit breaker, thereby reducing safety risks.

The first outer flange 11 and the second outer flange 12 are connected to each other, so that the second lower arc-shaped shell 5 and the annular shell 2 are detachably connected, which is conducive to installation and disassembly, easy to maintain, and has low maintenance cost.

[0048] The annular shell 2 has a third upper arc shell 13 and a fourth lower arc shell 14. The two ends of the third upper arc shell 13 are detachably connected to the four lower arc shells.

[0052] See also Figure 1 In this embodiment, the installation height of the first slide rail 6 and the second slide rail is lower than the two ends of the second lower arc shell 5, so that the roller 7 of the first upper arc shell 4 is not easy to roll out of the slide rail.

[0053] See also Figure 1 , the specific use steps of the housing of the hydraulic spring operating mechanism of the high-voltage circuit breaker that can be inspected without removing the cover in this embodiment are as follows: first, the operator unlocks the lock groove 9 and the lock tongue 10 on the lock buckle 8, and the operator grasps the first upper arc shell 4 of the annular inner shell 3, so that the several rollers 7 of the first upper arc shell 4 roll on the first slide rail 6 and the second slide rail on the inner wall of the annular inner shell 3, so that the first upper arc shell 4 is away from the annular outer shell 2 of the shell body 1, so that the pressure is released before the maintenance is carried out, so as to avoid the circuit breaker energy storage spring suddenly releasing the pressure and accidentally injuring the operator during the cover removal process. After the maintenance is completed, the first upper arc shell 4 is pushed so that the lock groove 9 and the lock tongue 10 on the lock buckle 8 fit each other. At this time, the first upper arc shell 4 and the third upper arc shell 13 are closed, which effectively prevents debris from falling into the mechanism and causing electrical or mechanical damage.
