Description

Technical Field

[0001] This utility model relates to the field of dual-power automatic transfer switch technology, specifically a dual-power automatic transfer switch. Background Technology

[0002] An Automatic Transfer Switch (ATS) is a device used to ensure a continuous power supply to critical loads. Its main function is to automatically switch to a backup power supply when the main power supply (primary power supply) fails or experiences voltage abnormalities, thus ensuring the normal operation of electrical equipment. An ATS typically consists of a power input terminal, a load output terminal, a switching mechanism, and a control unit. The control unit is responsible for monitoring parameters such as voltage and current of the primary power supply and issuing a switching command when an abnormality occurs, driving the switching mechanism to achieve seamless switching between the two power sources.

[0003] Currently, most dual-power automatic transfer switches on the market adopt a "point-to-surface" or "curved-surface-to-point" contact structure. When the motor-driven mechanism switches power, the force on the switch handle is concentrated, which can easily lead to localized wear, resulting in unstable switching action and even poor contact, affecting the power switching efficiency. Due to uneven force during the switching process, the switch handle may deform or wear, causing the switching mechanism to jam and affecting the overall service life of the equipment. In addition, unreasonable design of the mechanical contact points may also lead to arc elongation, increasing the risk of contact oxidation and affecting the electrical performance of the switch. Therefore, there is an urgent need for a dual-power automatic transfer switch to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-power automatic transfer switch to solve the problem mentioned in the background art of the current dual-power point-to-surface contact or curved-surface-to-point contact affecting equipment operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-power automatic transfer switch, comprising a base plate and a controller. The controller is fixedly mounted on the top front end of the base plate, and switches are installed on both sides of the controller. A motor is fixedly connected inside the controller, and the output shaft of the motor extends to the outer wall of the controller and is fixedly sleeved with a main shaft. A swing arm is movably sleeved on the outside of the main shaft. Switch handle push blocks are fixedly connected to both sides respectively, and the switch handle push blocks contact the switches to achieve closing and opening.

[0006] As a further technical solution of this utility model, the switch handle push blocks are symmetrically distributed about the main axis, and the front ends of the two sets of switch handle push blocks are respectively fixedly equipped with a commonly used switch status indicator and a spare switch status indicator.

[0007] As a further technical solution of this utility model, the motor is externally fixedly connected to a motor bracket, and the motor is fixed to the outer wall of the base plate through the motor bracket.

[0008] As a further technical solution of this utility model, the commonly used switch status indicator and the standby switch status indicator are red, white and green indicator lights from bottom to top.

[0009] As a further technical solution of this utility model, the front end of the motor bracket is provided with a common micro-control switch and a spare micro-control switch, which are located below the swing arm.

[0010] As a further technical solution of this utility model, the controller is equipped with an openable outer shell, and the outer shell is provided with a window for indicating the status of the commonly used switch and the status of the spare switch.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the dual power supply automatic transfer switch not only solves the various problems caused by point-to-surface contact or curved-surface-to-point contact of dual power supplies, but also enables electricians to accurately know the current status of the dual power supplies and avoid accidents.

[0012] (1) By setting up a motor, main shaft, swing arm, switch, and switch handle push block, the main shaft is driven to rotate by the forward and reverse rotation of the motor. The main shaft and the swing arm are linked to drive the switch handle push block to drive the switch to close and open, thereby completing the switching of the left and right power supply. The switch handle push block and the swing arm are connected by a cylinder and can rotate freely 360 degrees. This not only facilitates assembly and saves time, but also ensures that the switch handle push block and the switch handle are always in parallel surface-to-surface contact to receive force, which improves the mechanical and electrical service life of the dual power switch and solves the various problems caused by point-to-surface contact or curved surface-to-point contact in this type of dual power supply.

[0013] (2) By setting up a switch handle push block, a normal switch status indicator and a standby switch status indicator, and a switch, the normal switch status indicator and the standby switch status indicator are added to the switch handle push block. The normal switch status indicator or the standby switch status indicator is linked with the switch handle push block to accurately reflect the current position of the switch. The switch status indicator has three colors: green, white and red. Through the window of the outer casing, the electrician can accurately know the current status of the dual power supply and avoid accidents. Attached Figure Description
