A new type of three-stage bypass manual on-load transfer switch appliance

Abstract

A novel three-section bypass manual on-load switch appliance including bypass components, Box assembly, ontology component, Screw One, Connecting Plate, Five-link assembly, crank assembly, Drive linkage assembly, Contact plate 1, a rotating shaft, a contact plate, a bottom plate, a side plate, a side plate, a side plate, a screw, a side plate, a side plate, an interlocking member, an interlockingmember, a shaft, a power supply, a sleeve, a handle, a power supply, a guide rail, a snap contact, an interlocking member, an interlocking member, a pulley, a handle, a sector block, a shaft, a bracket, a connecting rod, a spring, a connecting plate, a connecting plate, a connecting plate, a shaft, a connecting plate, a shaft and a bracket; A main body assembly is arrange on that front side of thebox assembly through a guide rail, and is connected with a contact plate 1 and a contact plate 2 on the bypass assembly through a snap contact. The novel three-stage bypass manual on-load switch hassimple structure, and is reliable and operated manually and irrelevant to manpower. It mainly plays a redundant role and is easy to realize three-position function.

Description

technical field [0001] The invention relates to the technical field of transfer switch appliances, in particular to a novel three-stage bypass manual on-load transfer switch appliance. Background technique [0002] The double-bypass transfer switching equipment is composed of the automatic transfer switching equipment (ATSE) of the main circuit, the manual transfer switching equipment (MTSE) of the bypass and other necessary devices. When the MTSE is connected to the power supply on the same side, the ATSE can be withdrawn or inserted into the main circuit. The bypassed MTSE can switch between two power sources to ensure the power supply to the load. As a bypass electrical appliance, MTSE mainly plays a redundant role, and is operated independently by manpower. The operating power of MTSE is human. [0003] Because the main function of bypass products currently on the market is that the main body needs to be overhauled or maintained, the bypass plays a role of temporarily...

Problems solved by technology

[0003] Because the main function of bypass products currently on the market is that the main body needs to be overhauled or maintained, the bypass plays a role of temporarily replacing the power supply of the main body, but when the main body is overhauled or maintained, the normal power supply or the backup power supply fails. The bypass can not play the role of on-load conversion switching power supply circuit
