Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment.

[0025] Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] Such as Figure 1 to Figure 7 As shown, the embodiment of the present invention adopts electric and manual operation of three CJK5 vacuum contactors to realize star-delta conversion of high-power motor current-limited startup. It is mainly composed of three CJK5 vacuum contactors and mounting brackets. To start and run the motor, 3 AC vacuum contactors are usually used. Usually, KM1 and KM3 a...

Abstract

The invention discloses an integrated manual electric star-delta starting mechanism. It includes a vacuum contactor and a control part. The control part includes a mounting bracket, a tangential driven cam, a turntable, an outer shaft, and an interlock lock. The interlock lock is rotatably connected to the installation bracket. The bottom of the outer shaft The end of the cam is rotatably connected with the mounting bracket, the outer peripheral side wall is fixedly connected with the turntable, the top end of the tangential driven cam is connected with the turntable, the bottom end is connected with the switch part of the vacuum contactor, and the turntable Rotate to drive the driven cam to push the switch part of the vacuum contactor. The invention can solve the problem of lack of fire-fighting mechanical emergency equipment in the traditional fire-fighting starting cabinet.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to an integrated manual electric star-delta starting mechanism. Background technique [0002] At present, in the field of fire protection, it is required to add fire-fighting mechanical emergency equipment to the traditional fire-fighting starter cabinet. The purpose is to mechanically start the fire-fighting water pump manually when the electrical circuit of the fire-fighting starter cabinet fails, adding an insurance for fire-fighting. [0003] According to the actual needs of the market, Electric has developed a flashlight integrated device, that is, the electric circuit is connected and disconnected by the electromagnetic coil and spring of the vacuum contactor as the power operation circuit, and the circuit can also be connected and disconnected manually through a mechanical mechanism to change the motor. The phase winding Y-△ supplies power to the main circuit at the s...
