Problems solved by technology
[0002] At present, many important occasions use dual-power automatic transfer switches to supply power to electrical appliances. The rotating handles in the circuit breaker structure of dual-power automatic transfer switches are realized by pins or external rotating shafts, and the operating mechanisms generally use levers and rotating handles. The circuit breaker is opened and closed in the form of parts, and its structure is relatively complicated. After long-term use, the stability will decrease, which will affect the reliability of the work.

The invention relates to a dual power source automatic transfer switch including a common circuit breaker set and a backup circuit breaker set. An operation mechanism is arranged between the common circuit breaker set and the backup circuit breaker set. A rotary handle is arranged between the common circuit breaker set and the backup circuit breaker set. A shaft hole is arranged in the shaft center of the rotary handle. An inner rotary handle is arranged in the shaft hole. An end of the inner rotary shaft extending to the operation mechanism is provided with a rocking arm. The inner rotary shaft is in linked connection with the operation mechanism through the rocking arm.
Description
technical field [0001] The invention relates to a double power supply automatic transfer switch. Background technique [0002] At present, many important occasions use dual-power automatic transfer switches to supply power to electrical appliances. The rotating handles in the circuit breaker structure of dual-power automatic transfer switches are realized by pins or external rotating shafts, and the operating mechanisms generally use levers and rotating handles. The circuit breaker is opened and closed in the form of components, and its structure is relatively complicated. After long-term use, the stability will decrease, which will affect the reliability of the work. Contents of the invention [0003] In view of this, aiming at the above-mentioned shortcomings, the present invention provides a dual-power automatic transfer switch to solve the above-mentioned problems. [0004] In order to achieve the above purpose, the present invention adopts such a dual power automatic...
