Abstract

The invention provides an energy storage spring operating mechanism of a low-voltage isolation dual-power change-over switch; the mechanism comprises a main shaft, a cam, a connecting shaft, a first clamping plate, a second clamping plate, a first energy storage assembly, a second energy storage assembly, a long connecting rod, a first deflector rod, a short connecting rod and a second deflector rod; a cam heavy arm sleeves the periphery of the main shaft; the long connecting rod and the short connecting rod are hinged to the two side walls of the cam respectively, the middle of the first deflector rod, the first clamping plate, one end of the second energy storage assembly and the second clamping plate are sleeved with the periphery of the first hinge shaft, and the middle of the second deflector rod, the second clamping plate, one end of the first energy storage assembly and the first clamping plate are sleeved with the periphery of the second hinge shaft. According to the energy storage spring operating mechanism of the low-voltage isolation dual-power change-over switch, the idle running grooves in the upper connecting rod, the lower connecting rod and the deflector rods are used for ensuring that the operation speed of an operator is irrelevant to the action of the switch, so that a contact can be quickly opened and closed, and the accident that the contact in the switch is burnt down is avoided.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an energy storage spring operating mechanism of a low-voltage isolation dual power supply transfer switch. Background technique [0002] Dual power conversion switch is a widely used terminal electrical appliance, which mainly controls the action of the contact system through the operating mechanism to switch on or off the common power supply and backup power supply, so as to ensure the safety of the power system and the continuity of production. When one of the power supplies fails and needs to be repaired, the transfer switch needs to keep the two power supplies at an effective isolation distance, which requires the use of low-voltage isolation dual power supply switch appliances. [0003] The currently commonly used low-voltage isolation dual power switch mainly includes a housing, a contact system, a conversion mechanism and a manual automatic operati...
