specific Embodiment approach

[0025] The vacuum circuit breaker of this specific embodiment realizes cutting off the current of the primary circuit under the high-voltage circuit. There are three main operations: 1. Energy storage operation; 2. Closing operation; 3. Opening operation. The specific implementation methods are as follows:

[0026] 1. Energy storage operation: After the energy storage motor 4 is powered on, its output gear 4-1 rotates, and the rotation of the output gear 4-1 drives the clutch gear 5-1, shaft key gear 5-2, and energy storage gear 6 to rotate in turn The energy storage gear 6 rotates to stretch the energy storage spring 8; when the energy storage spring 8 reaches the highest point and moves forward to a certain position, the roller 6-3 contacts the closing detent 7, thereby limiting the energy storage The gear 6 continues to move, and the energy storage spring 8 is kept in a stretched state, while the jack 6-1 on the energy storage gear 6 pushes the clutch gear 5-1 to make the cl...

Abstract

The invention discloses a side-mounted vacuum circuit breaker, and relates to the technical field of circuit breakers. The side-mounted vacuum circuit breaker comprises an operating mechanism and primary major loops, the primary major loops are installed on the rear side of a framework of the miniaturized operating mechanism, the primary major loops are installed side by side in the side direction, and a body of the operating mechanism is arranged in a front-rear mode. The operating mechanism comprises a case, an energy storage and maintenance part, a closing / opening part and a transmission part. The energy storage and maintenance part and the closing / opening part are main operating parts and are installed on the front side of the operating mechanism, and the transmission part is installed on the rear side of the operating mechanism. The primary major loops can be solidly-encapsulated poles and can be installed in insulating cylinders. The side-mounted vacuum circuit breaker has the advantages that the internal structure is compact, the parts and components are simple and reliable, the width of a case body is only 210 mm, so that the problem that an existing vacuum circuit breaker matching cabinet body is large in size is effectively solved, and the technical problem that the matching cabinet body is 450 mm wide is particularly solved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a side-mounted vacuum circuit breaker. Background technique [0002] The existing vacuum circuit breaker has a complex manufacturing process, many parts, and is affected by its operating structure, so its width is relatively large, which seriously affects the requirements for miniaturization of power distribution. [0003] For example, the patent announcement number is 200810229103.X of the fixed side-mounted vacuum circuit breaker, its operating structural components are distributed in the four operating spaces of the box body, and there are many parts and bulky. [0004] Another example is the side-mounted vacuum circuit breaker disclosed in Patent No. 200820030836.6. Although it is relatively simple, its closing and opening components are distributed on both sides of the box, occupying a large space, and its minimum width can only be 240mm.
