Problems solved by technology

Therefore, conventional contactors typically consume a higher amount of electrical power
While at least some known contactors incorporate a mechanism to hold the power contacts of the contactor in the closed armature position, these contactors may still require a separate control circuit to release the latched state of the mechanism

Embodiment Construction

[0016] Exemplary embodiments of controlling contactors to achieve energy savings for the contactors are described herein. The contactor control circuit includes: a power supply; an energy storage system coupled to the power supply; a controller; a first transducer configured to switch at least one power contact from an open armature position to a closed armature position; a latch a latch system configured to retain the at least one power contact in the closed armature position; and a second transducer configured to disengage the latch system such that the at least one power contact switches from the closed armature position to the open armature position Location. A controller controls electrical power supplied to the first and second transducers to selectively activate the first and second transducers and to control operation of the contactors.

[0017] figure 1 is a perspective view of an exemplary contactor 10 . The contactor 10 uses at least one power contact ( figure 1...

Abstract

A control circuit is provided for an energy-saving contactor including at least one power contact. The circuit comprises: a supply unit; an energy storage circuit coupled to the supply unit; a first transducer coupled to the supply unit and designed to switch the at least one power contact from an open-armature position to a closed-armature position; a locking system designed to maintain the at least one power contact in the closed-armature position; a second transducer coupled to the supply unit and designed to de-couple the locking system in order to cause the at least one power contact to switch from the closed-armature position to the open-armature position; and a controller designed to control the electrical energy supplied from the supply source to the first and second transducers, in order to selectively activate the first and second transducers based on monitored input voltage states.

Description

technical field [0001] The field of the invention relates generally to electrical contactors, and more specifically to controlling the operation of electrical contactors. Background technique [0002] The electrical contactor is switched to control distribution of electrical power between the power source and at least one load. A contactor includes at least one power contact (ie, a switch) that can be selectively opened or closed to interrupt or supply electrical power flowing from a power source to a load. The load may be, for example, an electric motor, a lighting device, a heating device, an appliance or another electric device. [0003] At least some known contactors generally include a solenoid that, when energized, switches the positioning of the power contacts. In order to maintain this state, constant power must be supplied to the solenoid. Therefore, conventional contactors typically consume relatively high amounts of electrical power. Although at least some kno...
