Description
Art
The present invention relates to a kind of production and method of attachment of AC/DC contactor, especially a kind of producer can significantly reduce costs, and user significantly can reduce energy consumption, reduce heating and the electromagnetic switch of noise or the coil production of little stroke power take-off and method of attachment.
Background technology
At present, various types of contactor has LAP from being opened to close, and in order to ensure the reliability of closing stroke, the coil of all types of contactors is all for herein is provided enough large power, so just waste much electricity, and produce a large amount of heat and noise, shorten useful life, as long as and contactor close after very little electric current just can maintain, for this reason, have the method for several step-down current limliting, but these methods turn increase some control device, production cost rises again.So far also do not have significantly to reduce the product that production cost significantly reduces again use cost simultaneously.
Summary of the invention
Object of the present invention aims to provide a kind of production and method of attachment of contactor coil, significantly can reduce the production cost of manufacturer, significantly can reduce again the use cost of user, and reduces heating noise, increases the service life.
The technical solution adopted for the present invention to solve the technical problems is: based on the original coil of contactor, according to situations such as security needs, power, stroke gaps, line with 1/2,1/3 or 1/4 of the coil wire diameter in original contactor accordingly around original coil-winding total length 1/2,1/3 or about 1/4 coil, accordingly using 2,3 or 4 not only the thin number of turn but also few coil replace the original coil in contactor as one group of coil, save copper cash respectively 3/4,8/9 or about 15/16; Before energising is closed these 2,3 or 4 not only carefully the number of turn but also few coil (1) by the multi-joint electromagnetism linked switch (5) on contactor or electronic switching circuit and electric power generating composition parallel circuits, after energising is closed, these coils (1) are by the multi-joint electromagnetism linked switch (5) on contactor or electronic switching circuit and electric power generating composition series circuit.For 1/2 wire diameter 1/2 coiling total length, 2 coil D.C. contactors (Fig. 1): coil (1) is owing to being 1/2 wire diameter, so sectional area is original 1/4, again because coiling total length is original 1/2, so each coil resistance is original 2 times; In parallel by 2 (or electronic switching circuit) in multi-joint electromagnetism linked switch (5) before energising adhesive, each coil bears supply voltage, it is 2 times of original voltage, so before energising adhesive electric current with originally identical, because 2 coil total coiling total lengths of coil (1) are with originally identical, so suction is constant, normal adhesive; After adhesive, 2 coils pass through the action of electromagnetism linked switch (5) or electronic switching circuit, cut off original circuit, and by diode (2), circuit is seamlessly switched to series circuit, because each coil bears the half of supply voltage, so electric current reduces to original 1/4, energy consumption heating declines to a great extent; Shutdown transient, self-induction high pressure is eliminated in two coils (1), two diode (2) composition closed-loop paths.3 groups or many group coils are the same with 2 groups of coils, by electromagnetism linked switch (5) or electronic switching circuit, several coil and power sources in parallel before adhesive, with power sources in series after adhesive, and be parallel to series connection with diode (2) elimination self-induction high pressure, seamless switching.
The invention has the beneficial effects as follows: adopt 2 coils to be the coiling that (Fig. 1) of one group can save about 75%, economize on electricity nearly 75%; Employing 3 coils or more are the coiling that (Fig. 2) of one group can save about 89%, economize on electricity nearly 89%; Low so generate heat, noise is little, the life-span is long, effectively reduce manufacturer production cost, reduce customer using cost.
