Disconnecting switch with state indication device

Abstract

The invention discloses a disconnecting switch with a state indication device. The disconnecting switch comprises a pedestal, a left gate, a right gate, and a disconnecting link; the disconnecting link and the right gate are hinged. The disconnecting switch is characterized in that the switch also includes a disconnecting link state indication device including a first button, a second button, a first indication lamp, and a second indication lamp, wherein the first indication lamp and the second indication lamp are connected with the first button and the second button electrically. A left ejector rod and a right ejector rod are arranged on the disconnecting link. During a closing process, the left ejector rod compresses the first button, the disconnecting link opens and rotates around the right gate thoroughly, and the right ejector rod compresses the second button. According to the invention, the buttons are arranged at the closing position and the disconnecting position of the disconnecting link of the disconnecting switch to determine whether the closing is carried out correctly and disconnection is carried out thoroughly; and an indication lamp and a buzzer are arranged to warn the operator, so that a phenomenon that the closing is not carried out in place or disconnection is not done completely can be prevented. Therefore, the security of the disconnecting switch is improved and the disconnecting switch has the broad application prospects.

Description

technical field [0001] The invention relates to an isolating switch with a state indicating device, belonging to the technical field of power supply devices. Background technique [0002] During the manual operation of the isolating switch, due to differences in the habits, operation methods and strength of different operators, it is easy to cause accidental closing of the knife switch due to incomplete closing, resulting in false connection between the knife switch insurance and the contact point, or incomplete breaking. , Although the closing is not in place, although the circuit can be temporarily turned on, as the load increases, it is easy to cause overheating and burning of the dynamic and static contacts, and accidental closing is likely to cause personal injury to maintenance personnel. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, to provide a disconnector with a state indicating device, wh...

[0002] During the manual operation of the isolating switch, due to differences in the habits, operation methods and strength of different operators, it is easy to cause accidental closing of the knife switch due to incomplete closing, resulting in false connection between the knife switch insurance and the contact point, or incomplete breaking. If the switch is not in place, although the circuit can be temporarily turned on, as the load increases, it is easy to cause overheating and burning of the dynamic and static contacts, and accidental switch-on may easily cause personal injury to the maintenance personnel.
