Embodiment Construction

[0009] A manufacturing process of an on-load tap changer with a manual shift mechanism mainly includes the following steps: providing a manual shift mechanism on the cover plate of the on-load tap changer. The structure of the on-load tap changer with manual shift mechanism manufactured by the present invention will be further described in detail below in conjunction with the accompanying drawings. Referring to FIG. 1 , a manual shift mechanism 200 is fixed on the cover plate of the on-load tap changer 100 by screws. The structure of the manual shift mechanism, referring to Fig. 2, the upper bevel gear set 202 is installed in the upper gear box 201, and it is connected with the crank handle 203, the horizontal rotation from the crank handle speeds up through the pair of bevel gears and turns to vertical rotation. The lower bevel gear 204 group is installed on the back seat of the motor through the gear seat 207, and the small bevel gear 206 is installed on the rear extension e...

Abstract

The invention discloses a fabrication technology of an on-load tapping changing switch with a manual selector mechanism, mainly comprising the following procedures: a cover board of the on-load tapping changing switch is provided with the manual selector mechanism. With reasonable art and amazing concept, the invention adds a function on the prior switch structure. The invention is further provided with a pylome and eight screws on the prior switch cover and other structures do not need to be changed, which brings convenience for the debugging without current of a transformer and has great popularized value.

Description

technical field [0001] The invention relates to the technical field of electrical switch manufacturing, in particular to a manufacturing process 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 an on-load tap changer with a manual shift mechanism 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 following technical s...
