Energy-saving and anti-shake controller circuit of contactor

Abstract

The invention discloses an energy-saving and anti-shake controller circuit of a contactor. The controller circuit comprises an electronic energy-saving modular circuit (08) for the contactor and an electronic energy-saving modular full-voltage automatic time-sharing batching restart control circuit (013), wherein the electronic energy-saving modular circuit (08) for the contactor consists of a full-voltage AC (Alternating Current) (DC (Direct Current))-DC conversion circuit (04) with a short-circuit protection function, a full-voltage "intelligent switch-on operation" and low-voltage holding circuit (06) and a voltage inverse pulse width time occurrence circuit (07); and the energy-saving modular full-voltage automatic time-sharing batching restart control circuit (013) consists of a low-pass filtering full-voltage AC (DC)-DC conversion circuit (011) with an automatic working voltage interval option function, and a multifunctional time-sharing restart signal occurrence and control circuit (012). The controller circuit adopts a control voltage Us inverse time pulsed full-voltage start, wide-voltage and constant-power output low-voltage DC holding and automatic shake and outage time-sharing batching restart technology.

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...

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 many contactor power-saving products and anti-sway products on the market, but these products do not have the advantages of traditional AC contactors and DC contactors. Therefore, it has not been selected by complete sets of equipment; none of the existing anti-shaking 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.
