Embodiment Construction

[0009] Such as figure 1 :The bottom plate 1, the circuit breaker 2, the swing 3, the rotating part 4, the fixed part 5, the motor shaft 6, and the fixed part slot 7;

[0010] As shown in the figure: a dual power switch actuator, including the bottom plate 1, the circuit breaker 2, the swing 3, the rotating part 4, the fixed part 5, the motor shaft 6, the fixed part slot 7; the circuit breaker 2 is fixed on the bottom plate 1 . The motor shaft 6 passes through the rotating part 4 and is connected to the bottom plate 1, and the motor shaft 6 drives the rotating part 4 to rotate. One end of the push pendulum 3 is fixed on the rotating part 4 and the other end is fixed on the circuit breaker 2. The fixing member 5 connects the bottom plate 1 and the rotating member 4. The rotating part 4 is provided with a fixing part groove 7, and the fixing part 5 passes through the fixing part groove 7 to limit the moving range of the rotating part 4.

[0011] When the present invention is in us...

Abstract

The invention provides a dual-power supply switch execution mechanism, which comprises a bottom plate, breakers, a rotating part, fixed parts, fixed part grooves, a motor shaft and push pendulums. The dual-power supply switch execution mechanism is characterized in that the breakers are fixed on the bottom plate; the motor shaft passes through the rotating part, is connected to the bottom plate and drives the rotating part to rotate; one end of each push pendulum is fixed on the rotating part and the other end is fixed on the corresponding breaker; and each fixed part passes through the corresponding fixed part groove and is connected with the bottom plate and the rotating part. Due to the technical scheme, the positions of the breakers are changed into the upper part of the execution mechanism for placement in parallel from two sides of the execution mechanism in the past, so that the volume of a dual-power supply switch is reduced. Displacement operation is carried out by the same rotating part, so that the rotating resistance is reduced. A linked closed mechanism comprises a switch bottom plate, the rotating part and the breakers, so that the rigidity of the whole mechanism is improved; and the dual-power supply switch execution mechanism is relatively safe and reliable.

Description

Technical field [0001] The invention belongs to the field of electrical technology, and particularly relates to a dual power switch actuator. Background technique [0002] Dual power supply is a device used to start switching between grid power and grid power or grid power and generator power in a grid system, which can make the power supply continuous source supply. When the common power suddenly fails or fails, the dual power switch will automatically switch to the backup power source (the backup power source can also be powered by the generator under small load) so that the equipment can still operate normally. It is widely used in high-rise buildings, communities, hospitals, airports, docks, fire fighting, metallurgy, chemical industry, textiles and other important places where power outages are not allowed to realize unattended continuous power supply. [0003] The existing dual power switch mainly adopts an integral structure. The breaking element and the actuator are instal...
