A switch cabinet operating mechanism

Abstract

The invention belongs to the technical field of high-voltage electrical equipment, and relates to a switching cabinet operating mechanism. The switching cabinet operating mechanism is used for a switching cabinet with a linkage mechanism of a disconnecting switch and a grounding switch. The switching cabinet operating mechanism comprises a switching-off handle, a switching lever, a switching-off indicator, a switching-on indictor, an energy storage spring, an energy storage handle, an operating panel and a switching-on and separating switch controlling the disconnecting switch, the grounding switch and a cabinet door. Interlocking brake is achieved between the brake switch and the linkage mechanism of the disconnecting switch and the grounding switch so that the separating of the grounding switch and locking of the switching cabinet can be achieved while the switching of the disconnecting switch is achieved, and the switching of the grounding switch and opening of the switching cabinet can be achieved while the separating of the disconnecting switch is achieved. The switching cabinet operating mechanism is simple in structure, and the switching-on and switching-off switch capable of achieving integrated interlocking brake of the grounding switch, the disconnecting switch and the cabinet door is achieved. The switching cabinet operating mechanism is flexible in operation and low in failure rate, and an operator can carry out fault overhauling and normal maintaining work.

Description

technical field [0001] The invention relates to the technical field of high-voltage electrical equipment manufacturing, in particular to a switch cabinet operating mechanism. Background technique [0002] Switchgear is a device used to connect, disconnect and protect power supply lines and cooperate with relay protection to remove faulty lines. When the power supply line or equipment fails and during normal maintenance, it is necessary to turn off the vacuum switch in the switch cabinet, disconnect the isolating switch, and close the grounding switch before opening the cabinet door for operation. At present, the operator needs to operate the vacuum switch, isolating switch, and grounding switch separately through the closing and opening switches on the operating mechanism of the switch cabinet. In addition to the gate switch, there is also a separate mechanism for interlocking with the cabinet door, such as the invention patent application 201310141254.0. The operation is ...

Problems solved by technology

At present, the operator needs to operate the vacuum switch, isolating switch, and grounding switch separately through the closing and opening switches on the operating mechanism of the switch cabinet. In addition to the gate switch, there is also a separate mechanism that interlocks with the cabinet door, such as the invention patent application 201310141254.0

This operation is cumbersome, and if the operator is not skilled in the operation, it will lead to operational errors. Opening the cabinet door while the isolating switch is not disconnected will cause safety hazards, and the operation is not flexible enough and the failure rate is high.
