Embodiment Construction

[0008] A manufacturing process of a manual shift mechanism for an on-load tap changer, which mainly includes the following steps: A. Install the upper bevel gear set in the upper gear box, which is connected to the crank; B. Install the lower bevel gear on the motor On the rear seat, the small bevel gear set is installed at the rear extension end of the motor shaft, and the two parts are connected through the middle slot structure. The structure of the manual shift mechanism of the on-load tap changer manufactured by the present invention will be further described in detail below in conjunction with the accompanying drawings. Referring to the accompanying drawings, the upper bevel gear set 20 is installed in the upper gear box 10, and it is connected with the handle 30, and the horizontal rotation from the handle is accelerated by the pair of bevel gear sets and turned to vertical rotation. The lower bevel gear set 40 is installed on the back seat of the motor through the gear...

Abstract

The invention discloses a process for manufacturing a manual shift mechanism of an on-load tap-switch, mainly comprising the following steps that: A) an upper bevel gear unit is arranged in a gear box and is connected with a crank; B) a lower bevel gear unit is arranged on a rear seat of a motor, a bevel pinion unit is arranged on the rear extended end a motor shaft; and the upper bevel gear unit and the lower bevel gear unit are connected through a middle slot structure. The invention is reasonable in process and skillful in design and is developed form a prior switch structure without making any change but an additional function and one through hole and eight screw hole arranged on a cover of the prior switch. The invention facilitates the non-electric debugging of a transformer, thereby being worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of electrical switch manufacturing, in particular to a manufacturing process of a shift mechanism of an on-load tap changer. Background technique [0002] SY□ZZ type on-load tap-changer is the most commonly used voltage regulating switch for distribution transformers with a voltage level of 35KV and a current of ≤400A. It is a product widely used in domestic power distribution systems. In the current domestic products, there is no manual shifting mechanism, which brings inconvenience to the non-electric debugging of the transformer. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process of a manual shift mechanism of an on-load tap changer that can effectively overcome the above-mentioned defects and bring convenience to the non-electric commissioning of the transformer. [0004] In order to achieve the above object, the present invention adopts the fo...
