Problems solved by technology

However, when the load is transferred from the normal power supply to other backup power sources, it is prone to the situation that the normal power switch and the backup power switch are closed at the same time, which will cause safety accidents, and the transfer reliability needs to be improved.

Abstract

A two-switch rigid interlocking mechanism relates to the technical field of power equipment, and solves the technical problem of improving power conversion reliability. The mechanism comprises a frame, a main power switch mounted on the frame, and a backup power switch, wherein the free end of a switch moving contact drive rotating shaft of the main power switch is fixed with a first crank arm, and the free end of a switch moving contact drive rotating shaft of the backup power switch is fixed with a second crank arm; the frame is provided with a freely rotatable interlocking swing arm; when the main power switch is closed and the backup power switch is opened, the first crank arm is pressed against the left end of the interlocking swing arm, and the right end of the interlocking swing armis pressed against the lower end of the second crank arm, so that the backup power switch is locked; when the main power switch is opened and the backup power switch is closed, the second crank arm is pressed against the right end of the interlocking swing arm, and the left end of the interlocking swing arm is against the lower end of the first crank arm, so that the main power switch is locked.The mechanism provided by the invention can prevent the load from being simultaneously connected to two power sources.

Description

technical field [0001] The invention relates to electric equipment technology, in particular to a double-switch rigid interlocking mechanism technology. Background technique [0002] The power system is generally composed of power generation system, transmission line, power transformation system, power distribution system and power consumption equipment. In order to ensure the safe, reliable and continuous power supply requirements of the power transmission and distribution system, two or more power supply and distribution methods can generally be used to ensure that when the common power supply is abnormal, it can be immediately switched to other backup power supplies for operation. Or when the load of one power supply is too heavy, part of the load can be transferred to other power sources with margin, and the conversion on this circuit needs to be completed by the transfer switch system. The transfer switch system in the power system usually includes various electrical c...
