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 an automatic change-over switch comprising a mounting bracket, a driving gear, a left driven gear, a right driven gear, a left stirring member, and a right stirring member. Thedriving gear, the left driven gear, the right driven gear, the left stirring member, and the right stirring member are arranged on the mounting bracket. The left and right sides of the driving gear are respectively meshed with the left driven gear and the right driven gear; the left stirring member is meshed with the left driven gear; the right stirring member is meshed with the right driven gear;and one group of circuit breakers us arranged at the outer side of each of the left stirring member and the right stirring member. The driving gear drives the left stirring member and the right stirring member to move up and down alternately to realize changing of opening and closing of the two groups of circuit breakers. The upper parts of the left stirring member and the right stirring member are connected with a locking mechanism. The locking mechanism is used for stopping the simultaneous closing of the left stirring member and the right stirring member. The automatic change-over switch has a simple structure; and because of the locking mechanism, the occurrence of simultaneous closing of the circuit breakers on both sides is prevented effectively.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an automatic 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 a...
