A contactor energy-saving anti-shaking controller circuit

Abstract

The invention discloses a contactor energy-saving anti-shake electric controller circuit, comprising an electronic energy-saving module circuit (08) for a contactor and a full-voltage automatic time-division and batch-restart control circuit (013) for the electronic energy-saving module. The energy-saving module circuit (08) consists of a full-voltage AC (DC)-DC conversion circuit (04) with short-circuit protection, a full-voltage "smart closing operation" and a low-voltage holding circuit (06), and a voltage inverse-time pulse width time generation The circuit (07) is composed; the energy-saving module full-voltage automatic restart control circuit (013) is composed of a low-pass filter full-voltage AC (DC)-DC conversion circuit (011) with automatic working voltage interval selection function (011), It is composed of multi-function time-sharing restart signal generation and control circuit (012). The invention adopts the control voltage Us inverse time limit pulsating full voltage start, wide voltage, constant power output low-voltage direct current holding and automatic restarting technology in time and batches after power outage.

Description

technical field [0001] The invention relates to a controller circuit, in particular to an energy-saving and anti-shake controller circuit for a contactor. Background technique [0002] In the field of control electrical appliances, contactors and relays are very common electrical components. The disadvantages of existing contactors and relays: more than 90% of the holding power in the holding state is wasted in vain, and it is a heating power that is likely to cause failure; the control characteristics of the release voltage ≤ 70% Us; the coil is easy to burn, the contact Easy to wear and tear. Among them, the control characteristic of the release voltage ≤ 70% Us is the main reason for tripping and power failure when the power grid shakes. [0003] In order to solve the above shortcomings, there are also many contactor power-saving products and anti-sway products on the market, but these products do not have the advantages and advantages of traditional AC contactors and D...

Problems solved by technology

The disadvantages of existing contactors and relays: more than 90% of the holding power in the holding state is wasted in vain, and it is a heating power that is likely to cause failure; the control characteristics of the release voltage ≤ 70% Us; the coil is easy to burn, the contact Easy to wear

[0003] In order to solve the above shortcomings, there are also many contactor power-saving products and anti-sway products on the market, but these products do not have the advantages and advantages of traditional AC contactors and DC contactors, so they are not selected by complete sets of equipment; None of Akira's controller products has been recognized by the market and cannot meet user requirements.

After the contactor trips, the mechanical method (to maintain the fluid pressure) can reduce some economic losses, but it destroys the continuity of production and brings the trouble of manually restarting the assembly line.
