An isolation padlock device suitable for dual power automatic transfer switch

Abstract

The present invention relates to an isolation padlock device suitable for a double-power supply automatic switching switch. The isolation padlock device includes a mounting support, a main transmission shaft, a limiting sheet, a rocker arm, a locking sheet and a micro switch; the mounting support comprises a main plate and a side plate; a gap is left between the main plate and the side plate; a shaft hole is formed in the main plate of the mounting support; the main transmission shaft penetrates the shaft hole and is mounted on the main plate of the mounting support; the limiting sheet is arranged above the main plate of the mounting support and is located at the upper end of the main transmission shaft; the rocker arm is arranged below the main plate of the mounting support and is located at the lower end of the main transmission shaft; the locking sheet is mounted in the gap between the main plate and the side plate; and the micro switch is mounted on the inner wall of the side plate. With the isolation padlock device suitable for the double-power supply automatic switching switch of the invention adopted, electrical-mechanical double locking can be realized, and it can be ensured that the switch is in an isolation state. The isolation padlock device suitable for the double-power supply automatic switching switch of the invention has the advantages of simple structure, convenient operation and safe use, and can effectively prevent the occurrence of accidents and protect personal and property safety.

Description

technical field [0001] The invention relates to an isolation padlock device, in particular to an isolation padlock device suitable for a dual power automatic transfer switch. Background technique [0002] The purpose of the dual power automatic transfer switch is simply that one way is commonly used and one way is reserved. When the common power suddenly fails or the power is cut off, the dual power supply switch is automatically put into the backup power supply, so that the equipment can still operate normally. When the dual power automatic transfer switch fails and cannot be stably isolated, it may cause major safety accidents and endanger personal and property safety. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an isolation padlock device suitable for a dual power automatic transfer switch, which ensures that the switch is in an isolated position through electrical and mechanical double locking, the mechani...
