Abstract

The utility model relates to a dual-power automatic transfer switch, which comprises a commonly used circuit breaker arranged on the left side, a back-up circuit breaker arranged on the right side, and a motor, wherein both of the circuit breakers are provided with operating handles, a gear, two slide blocks and a bracket are arranged between the commonly used circuit breaker and the back-up circuit breaker, the slide blocks are provided with insections which are meshed with the gear, the gear is fixed on a rotary shaft of the motor, the slide blocks are arranged on both sides of the bracket by a fixed shaft, the gear is pressed by the bracket and is fixed together with the slide blocks after being meshed with the slide blocks, lead-out shafts of the operating handles on the circuit breakers are respectively arranged in grooves of the slide blocks, and in operation, the motor rotates to drive the gear on the rotary shaft of the motor and drives the slide blocks to move so as to drive the operating handles to switch on and switch off the circuit breakers. The product has simpler structure, and is easy to assemble, the slide blocks and the gear are unified to drive the operating handles on the circuit breakers, the action is flexible, and the operating force is light.

Description

Double power supply automatic transfer switch

Affiliated technical field: the utility model relates to the automatic conversion control device of a kind of duplicate supply.

Background technology: the double power supply automatic transfer switch that is widely used at present, all adopt special-shaped rotating disk, do not have gear, do not have metallic support, defective such as U-lag fluting is little in the special-shaped rotating disk, and bad assembling can exist action insensitive in the use, operating force is big.

Summary of the invention: in order to overcome above phenomenon, a kind of double power supply automatic transfer switch that the utility model provides, this switch adopt slide block and gear to unite and drive the switching manipulation handle, are active in one's movements, and operating force is light.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of double power supply automatic transfer switch, it comprises the circuit breaker commonly used that is installed in the left side and the back-up breaker on the right, motor, operating grip all is housed on the circuit breaker, be provided with gear between circuit breaker commonly used and the back-up breaker, two slide blocks and support, groove is arranged on the slide block, with the gear interlock, slide block upper and lower surface and side are all fluted, on the slide block, the groove on following two sides is stuck on the fixed axis, gear is fixed on the machine shaft, fixed axis is contained in the support both sides to slide block, support gear push down with the slide block interlock after be fixed together, and be screwed on base plate, operating grip on the circuit breaker is drawn axle and is respectively charged in the groove of slide block side, and during operation, motor rotates the gear that drives on the machine shaft, by the gear driven slide block, realize the circuit breaker branch thereby drive operating grip, close a floodgate.

The beneficial effects of the utility model are: product structure is simpler, easily assembling, and slide block and gear are united drive breaker operator handle, are active in one's movements, and operating force is light.

Among the figure: 1. right operating grip; 2. circuit breaker commonly used; 3. back-up breaker; 4. left operating grip; 5. support; 6. machine shaft; 7. base plate; 8. fixed axis; 9. slide block 10. fixed axis; 11. slide block; 12. gear; 13. fixed axis; 14. fixed axis.

Embodiment:

Shown in Fig. 1-4: a kind of double power supply automatic transfer switch, comprise circuit breaker commonly used (2), back-up breaker (3), left and right operating grip (1), (4) and operating mechanism, operating mechanism comprises machine shaft (6), support (5), base plate (7), slide block (9), (11), gear (12) and fixed axis (8), (10), (13), (14).

Shown in Figure 1: support (5) and slide block (9), (11) are connected between circuit breaker commonly used (2) and the back-up breaker (3) with left and right operating grip (1), (4), drawing in the groove of the side that is installed in slide block (9), (11) of left and right operating grip (1), (4), operating grip (1), (4) are installed on circuit breaker commonly used (2) and the back-up breaker (3).

Shown in Figure 2: gear (12) is fixed on the machine shaft (6).

Shown in Fig. 3-4: after gear (12) and slide block (9), (11) interlock, push down with support (5), fixed axis (8), (10), (13), (14) are contained on the support (5), with screw support (5) is fixed on the base plate (7), slide block (9), (11) can be in fixed axis (8), (10), (13), easy on and off slides above (14).

Among Fig. 1: when circuit breaker commonly used (2) and back-up breaker (3) were in two branch state, left and right operating grip (1), (4) all were in the parastate position respectively, and the handle of two circuit breakers also all must be in the separating brake position.

When needs circuit breaker (2) commonly used closes a floodgate, back-up breaker (3) separating brake, machine shaft (6) turns clockwise, the driven gear motion, thereby two slide blocks (9), (11) move up and down about driving, and the right operating grip (1) on the drive slide block draws axle and also moves upward, and circuit breaker (2) commonly used closes a floodgate, back-up breaker (3) separating brake.

When needs back-up breaker (3) closes a floodgate, circuit breaker (2) separating brake commonly used, machine shaft (6) is rotated counterclockwise, the driven gear motion, thereby two slide blocks (9), (11) move up and down about driving, and the left operating grip (4) on the drive slide block draws axle and also moves upward, and back-up breaker (3) closes a floodgate, circuit breaker (2) separating brake commonly used.
