Electrical accessory for auxiliary starting relay or alternating current contactor

Abstract

The invention discloses an electrical accessory for an auxiliary starting relay or an alternating current contactor. Compared with an existing product, electrical energy is saved by 65% to 80%; the calorific value of an electromagnetic coil is far less than existing calorific value, due to the fact that the calorific value of the coil is reduced, the ageing time of components and parts and insulating materials is greatly retarded, the service life of the relay is also longer, more than 90% of relays and alternating current contactors are burnt out due to excess temperature of the coil, fires further occur for several relays and alternating current contactors, the lethal link such as temperature is alleviated, except the ageing of natural materials, theoretically the service life of the working coil can be infinitely long; and the electrical accessory has ultra-wide working voltage, so that any fluctuation of network voltage can be met. In a 380 V circuit, the electrical accessory can normally and continuously work when the power supply is between 250 V and 500 V, an existing working power supply is generally between 300 V and 450 V, in a 220 V circuit, the electrical accessory cancontinuously and safely work when the power supply is between 150 V and 300 V, and an existing working power supply is generally between 180 V and 250 V; and alternating current electromagnetic vibration and noise are eliminated.

Description

technical field [0001] The invention relates to the technical field related to relays or AC contactors, in particular to an electrical accessory for a relay or an AC contactor that assists in starting. Background technique [0002] Both relays and AC contactors use the principle of electromagnet suction and release to realize their work, that is, the coil is wound on a custom-made iron core and then energized to generate an electromagnetic field, thereby attracting the dynamic balance iron to drive the contact to work. On this basis, a kind of electrical accessories for assisting the start-up relay or AC contactor is designed, combined with the inherent characteristics of the electromagnet, the principle of the field strength difference between the magnetic circuit opening and the magnetic circuit closing, and some electronic components supporting the work, it constitutes a special The working method is the energy-saving and other effects that the existing relays or AC conta...
