Dual-supply change over switch operating mechanism

Abstract

The invention provides a dual-supply change over switch operating mechanism. The dual-supply change over switch operating mechanism comprises an upper switch body, an upper rocking arm, a square shaft, a rotating shaft, a lower connecting rod, a lower rocking arm, an upper connecting rod and a lower switch body, wherein the square shaft is fixed on the rotating shaft, and the rotating shaft is provided with the upper rocking arm and the lower rocking arm; the upper rocking arm passes through a waist-shaped groove in the upper connecting rod and is pivoted to one end of the upper connecting rod, the lower rocking arm passes through a waist-shaped groove in a lower connecting rod and is pivoted to one end of the lower connecting rod 7, and the upper rocking arm and the lower rocking arm are arranged in an angle of 90 degrees; the other end of the upper connecting rod is connected with the upper switch body, and the other end of the lower connecting rod is connected with the lower switch body; and the square shaft rotates in an anticlockwise manner, when the upper rocking arm drives the upper connecting rod to be pushed to the left, the upper switch body is switched on, and when the square shaft rotates in a clockwise manner, the upper rocking arm drives the upper connecting rod to be pulled towards the right while the lower rocking arm drives the lower connecting rod to be pushed towards the left. The dual-supply change over switch operating mechanism has the following advantages: both manual operation and electrical operation are realized, it can be ensured that two switches are not simultaneously switched on, installation of a mechanical interlock is unnecessary, double switching-off positions exist, the structure is simple, and the safety and the reliability are high.

Description

technical field [0001] The invention belongs to the technical field of low-voltage power distribution dual-power automatic transfer switch, and in particular relates to an operating mechanism of a dual-power transfer switch. Background technique [0002] The traditional dual power supply opening and closing mechanism is directly driven by the electromagnet mechanism. The electromagnet mechanism has disadvantages such as large impact, short life, and poor reliability. When the voltage is low, the switching may fail to switch on and burn the electromagnet. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an operating mechanism for a dual power supply switch. [0004] The purpose of the present invention is accomplished through the following technical solutions. This double power conversion switch operating mechanism includes an upper switch body, an upper rocker arm, a square shaft, a rotati...
