Abstract

The invention discloses a three-position switching operation mechanism of a transfer switch, which comprises a rotating shaft externally connected to a contact system, a mounting bracket, a translation assembly, a clamping assembly and a coil group. The translation assembly is driven by the coil group to complete opening and closing of three positions, the clamping assembly locates the three positions, and the translation assembly drives the rotating shaft to complete opening and closing of the external connection to the contact system. Compared with the conventional gear assembly driven by motor, it is simpler in structure, avoiding the tedious meshing and wear between the original parts, and the whole movement is simple and stable. The three-position positioning is stable, which can limit two closing positions and one opening position well, and ensure the contact system connected with the rotating shaft to accurately limit the position after switching on and off, and the position ofopening and closing is stable. Coil-driven switching mode uses less energy, only instantaneous power-on to complete the mechanical lock can, usually does not consume energy, more energy-saving.

Description

technical field [0001] The invention relates to the field of electrical switches, in particular to a three-position opening and closing operating mechanism of a transfer switch. Background technique [0002] Transfer switches are widely used in various places that require uninterrupted power supply, which realizes the conversion of load lines between two power sources to ensure the reliability of power supply for users. In order to realize the opening and closing conversion of the contact system, the existing structure is to extend the rotating shaft from the contact system. The rotating shaft is driven by the operating mechanism to rotate, and the operating mechanism is connected to the motor, which is driven by the motor to rotate and switch. The operating mechanism itself also Can be rotated manually. The existing operating mechanism basically uses a gear structure for rotation transmission, lacks a relatively firm structure to limit the stop position of the operating me...
