Embodiment

[0035] This embodiment provides a dual-power automatic transfer switch, which is provided with an indicating mechanism for indicating the working state, such as figure 1 As shown, the indicating mechanism includes an indicating member 1 and a positioning mechanism.

[0036] The indicator 1 is arranged on the power output shaft 3 of the motor 6 and is arranged in conjunction with the power output shaft 3. The indicator 1 has three indicating positions: normal, standby and double. The power output shaft 3 is provided with a combination structure that can be positioned and connected with the positioning rod 4. In this embodiment, as figure 2 As shown, the coupling structure is a positioning groove 31 recessed inward from the outer wall of the power output shaft 3 , and the positioning groove 31 can be positioned and connected with the positioning rod 4 .

[0037] The positioning mechanism is adapted to limit the rotation position of the indicator 1 when it is switched from the...

Abstract

The invention provides an indication mechanism and a dual-power automatic change-over switch thereof. The indication mechanism comprises an indication part which is rotatingly disposed on a body and is provided with a common indication position, a standby indication position, and a dual-branch indication position; the indication mechanism further comprises a positioning mechanism which is suitablefor limiting the rotating position of the indicating part when the indicating part is switched from the common / standby indicating position to the double-branch indicating position. The double-branchindicating position is accurately positioned, misoperation is avoided, and the safety and the reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of dual power supplies, in particular to an indicating mechanism and an automatic transfer switch for dual power supplies. Background technique [0002] The dual power supply switch is used to continuously supply power. When the common power supply suddenly fails or fails, it can be automatically switched to the backup power supply through the dual power supply switch, so that the electrical equipment can still operate normally. [0003] The dual-power transfer switch has three working states: normal, standby, and double-split. The double-split state means that both the normal power supply and the standby power supply are in a disconnected state. The indication mechanism of the existing dual power supply switch is as follows: Figure 5 with 6 As shown, it includes a power output shaft 3 and an indicator 1 arranged on the drive shaft. The indicator 1 is provided with three status indicator marks. The indicat...
