Problems solved by technology

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 mechanism, and may cause unstable opening and closing positions
The general contact system uses a shaft to drive a moving contact to rotate, and a moving contact rotates to close the static contacts of the upper and lower chambers to realize two-way switching; a single moving contact switches back and forth, and the pressure it bears and wear are doubled, and the service life and performance of parts will be affected

Abstract

The invention discloses a transfer switch, which comprises a rotating shaft, a mounting bracket, a translation assembly, a clamping assembly and a coil group externally connected to a contact system.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 overall movement is simple and stable. On the other hand, the common circuit and the standby circuit are respectively provided with independentmoving contact and static contact, so that the electric repulsion force generated by the two closing paths is respectively assumed, so as to avoid the double pressure and wear of the single moving contact in use, thereby ensuring the performance of the contact system and prolonging the service life of the contact system.

Description

technical field [0001] The invention relates to the field of electrical switches, in particular to 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 mechanism, and may cause unstable opening and closing position...
