Problems solved by technology

Some of the current switches have their own position indicating mechanism, and the gear boxes used are often only used to transmit power, without considering the position indicating function. The gear positions of the switch and the electric mechanism box require one-to-one accurate connection. It requires a high professional level; especially when the switch and the electric mechanism box need to be maintained, the connection between the two is often disconnected. At this time, if the switch does not have a position indicating mechanism, once it is wrongly connected to the electric mechanism box The light one will damage the switch, and the serious one will cause a major accident of the transformer

Embodiment Construction

[0014] Such as figure 1 As shown in the external view of the existing gear box (1), the upper part is provided with a cover plate (2). The interior of the gear box is provided with a transmission mechanism of a helical gear or a worm gear.

[0015] Such as figure 2 In the shown embodiment, a position indicating mechanism (3) is added on the cover plate of the gear box (1).

[0016] Such as Figure 4 The sequence of assembly of the internal components of the position indicating mechanism shown is:

[0017] ① First connect the shift fork (33) and the rotating shaft (34) with elastic cylindrical pins;

[0018] ②Knock the two bearings (35) into the base of the position indicating mechanism (31) and fix them with elastic retaining rings in the holes;

[0019] ③Knock the shift fork and rotating shaft into the bearing from the bottom surface of the base and fix it with the shaft elastic retaining ring;

[0020] ④ Fix the ring gear I (36) on the base;

[0021] ⑤ Assemble the p...

Abstract

The invention discloses a gear box with a position indication function, and is applied to an on-load or no-load tap changer of a transformer. A planetary gear motion principle is adopted, and the position indication function is added on the basis of the only transmission function of the conventional gear box. Therefore, the switch has the position indication function, the design of the switch is perfected, and the shortcomings of the conventional design are overcome.

Description

technical field [0001] The invention relates to a transmission gear box of an on-load or off-load tap changer of a transformer, which adds a position indication function to the original gear box which is only used for transmission. Background technique [0002] The operation of transformer on-load and off-load tap-changers is usually divided into electric and manual. Electric operation has the power system of the switch itself and the switch itself has no power to provide operating power such as: electric mechanism box. To transmit power to the switch from the electric mechanism box, the connection between the two must be considered. The most common method is to use the bevel gear, helical gear, and worm gear mechanism in the gear box to change the direction of power transmission through the gear box to meet the requirements of the switch. Installation of switches and motor mechanism boxes on transformers. Some of the current switches have their own position indicating mech...
