Problems solved by technology

In the existing transfer switch, the cooperation between the operating mechanism and the toggle piece is relatively complicated, and there are many parts
Not only is the production and assembly time-consuming, but it is also prone to simultaneous closing of the circuit breakers on both sides, resulting in a short circuit and, in severe cases, endangering the safety of life and property

Abstract

The invention provides a change-over switch. The change-over switch comprises an installation frame and a driving gear, a left driven gear, a right driven gear, a left shifting member and a right shifting member separately arranged on the installation frame, the left side and the right side of the driving gear are respectively connected with the left driven gear and the right driven gear in an engaged manner, the left shifting member is connected to the left side of the left driven gear in an engaged manner, the right shifting member is connected with the right side of the right driven gear inan engaged manner, the outsides of the left shifting member and the right shifting member are respectively provided with a group of circuit breakers, the left shifting member and the right shifting member are driven by the driving gear to alternately move up and down to realize switching of switch-on and switch-off of the two groups of circuit breakers, the left shifting member and the right shifting member are connected through a locking mechanism, and the locking mechanism can prevent simultaneous switch-on of the left shifting member and the right shifting member. According to the change-over switch, the structure is simple, the locking mechanism is provided, and the condition of simultaneous switch-on of the circuit breakers at two sides can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a transfer switch. Background technique [0002] The transfer switch is widely used in various places that require uninterrupted power supply. It realizes the automatic conversion of the load line between the two power sources to ensure the reliability of the user's power supply. In order to realize the opening and closing conversion of two circuit breakers, what the known automatic transfer switch adopted at present is that the toggle brackets on both sides are controlled by the motor to drive the operating mechanism to move up and down alternately, and the toggle brackets drive the opening and closing of the circuit breaker switch. In the existing changeover switch, the cooperation between its operating mechanism and the toggle member is relatively complicated, and there are many parts. Not only is the production and assembly time-consuming, but it is also prone t...
