Knife switch type ignition device

Abstract

A knife switch type ignition device comprises a high-voltage sleeve (1), a fuse (2) and a rotating mechanism, the rotating mechanism comprises an upper-section type telescopic rod (3) and a lower-section type telescopic rod (3), a horizontal rotating shaft (4) and a ratchet mechanism are arranged at the top of an upper sleeve rod of the telescopic rod (3), and the ratchet mechanism comprises a ratchet wheel (5) and a poking needle (6). The ratchet wheel (5) is installed on the horizontal rotating shaft (4). The middle of the poking needle (6) is installed on the side face of an upper sleeve rod of the telescopic rod (3) and can rotate, the top of the poking needle (6) is inserted into a tooth gap of the ratchet wheel (5), the bottom of the poking needle (6) is connected with a spring (7),the ratchet wheel (5) is connected with a sliding block (8), and the sliding block (8) is connected with a rail (9). The top face of the rail is connected with a fuse (2) through an embracing hoop (10). The ignition device is compact in structure and has an obvious breaking point, the poking needle can prevent the ratchet wheel from rotating reversely, and high stability and safety are achieved.

Description

technical field [0001] The invention relates to the technical field of transformer ignition application, in particular to a knife switch type ignition device with strong adaptability and high safety. Background technique [0002] In order to ensure the continuous and stable power consumption of oil wells in the process of oil exploitation, the requirements for transformers are relatively high. Therefore, in order to facilitate the transportation, installation, commissioning and maintenance of transformers on site, the structure of transformers for oil wells is gradually becoming modular, intelligent and small. direction of development. [0003] A general transformer is connected to the high voltage of the external power grid through a drop-out fuse, such as an oil-immersed transformer commonly used outdoors. After all the components of the transformer are installed, you only need to use the insulating rod to toggle and close the drop-out fuse. It can achieve ignition, and i...

Problems solved by technology

Dropping generally means that it is affected by gravity after fusing, and it starts to swing from a tilted state to vertical. However, the design of the drop stroke of the drop-out fuse needs to be considered during installation, and a large space needs to be reserved for it, and this kind of fusing When connecting high-voltage bushings of different heights and positions, the adaptability is not strong, the installation and fixing are cumbersome, and often require a large space
