Abstract
The utility model discloses an energy saving and silencing contactor, which is characterized in that a voltage dependent resistor is adopted by a follow current element R, the turn number of a starting winding L1 is 1300 to 2000, the linear diameter of the L1 is 0.20 mm to 0.35 mm, the turn number of a sticking winding L2 is 10000 to 15000, and the linear diameter of the L2 is 0.7 mm to 0.12 mm. The utility model has the advantages that when the utility model is stopped, the ability of the prevention of the reverse over voltage peak is strong, and the prevention of burning out of a diode and the windings can be ensured.
Description
The utility model relates to a kind of contactor of controlling the threephase motor break-make.
Contactor is a kind of electric device that is used to control the threephase motor break-make, Chinese patent 91230993.8 provides a kind of energy-saving material-saving noise elimination contactor, the winding that substitutes single specification with different startup winding in the number of turn, line footpath and sticking winding, during startup, the startup winding work that the few line of number of turn footpath is big, the little sticking winding in the multi-thread footpath of the sticking stage number of turn is devoted oneself to work, and realizes reducing copper loss, power consumption, and temperature rise is little.The defective of this scheme be with diode as continued flow component, the ability that the peak of anti-the inverse overvoltage impacts is relatively poor; Next is that the used components and parts of contactor are more, and structure owes to simplify.
The purpose of this utility model is to provide that a kind of anti-inverse overvoltage peak energy power is strong, the economize on electricity noise elimination contactor of compact conformation.
This economize on electricity noise elimination contactor comprises base, arc-control device, iron core, armature, dynamic and static contact, start button, rectifying device starts winding, sticking winding and continued flow component, wherein start button is often to drive button, and continued flow component adopts piezo-resistance, and rectifying device comprises a rectifier bridge and a diode.Fig. 1 is the electrical structure schematic diagram of this contactor, and two inputs of rectifier bridge H connect AC power through start button K
The centre tap that starts winding L 1, sticking winding L 2 is connected with a end of rectifier bridge H, another tap that starts winding L 1 is connected with the b end of rectifier bridge H, another tap of sticking winding L 2 connects an end of power supply behind diode D, the two ends of piezo-resistance R and sticking winding L 2 also connect, when pressing start button K, the contactor energising starts, power supply is through full-wave rectification at this moment, and rectifier bridge H and startup winding L 1 form the loop, and it is in running order to start winding L 1; Start and finish, start button K often leaves, and power supply is through halfwave rectifier, and sticking winding L 2 is in running order; When contactor quit work, sticking winding L 2 constituted the loop with piezo-resistance R, and the inverse overvoltage peak that sticking winding L 2 produces is by piezo-resistance R afterflow.It is characterized in that continued flow component R adopts piezo-resistance, starting winding L 1 number of turn is 1300～2000 circles, its line directly is 0.20～0.35mm, sticking winding L 2 numbers of turn are 10000～15000 circles, and its line directly is 0.07～0.12mm, through preferred, starting winding L 1 number of turn is 1600～1700 circles, line directly is 0.29～0.32mm, and sticking winding L 2 numbers of turn are 12000～13000 circles, and line directly is 0.07～0.09mm.
With prior art relatively, the advantage of this programme is:
1. adopt piezo-resistance as continued flow component, its afterflow performance is better than diode, and when contactor quit work, anti-inverse overvoltage peak energy power was strong, can keep diode, winding not to be burnt effectively.
2. start winding and sticking winding respectively in Contactor Starting stage and the work of sticking stage, add that power savings is remarkable to the choose reasonable in umber of turn, line footpath.
3. economize and use auxiliary switch, structure is more compact.
Embodiment:
A kind of economize on electricity wave absorption contactor, adopt the structure shown in the accompanying drawing 1, start button K often leaves button, and starting winding L 1 number of turn is 1600 circles, line directly is 0.29mm, sticking winding L 2 numbers of turn are 12000 circles, and line directly is 0.07mm, and continued flow component R adopts the MYG500 piezo-resistance of withstand voltage 500V, electric circuit full-wave rectification when starting, halfwave rectifier during sticking, contactor dependable performance, not easy burn-out.
Claims (2)
1, a kind of economize on electricity noise elimination contactor comprises base, arc-control device, iron core, armature, dynamic and static contact, start button, rectifying device starts winding, sticking winding and continued flow component, wherein start button is for often leaving button, when taking start button off, and iron core adhesive, threephase motor operation; Start and finish, start button disconnects, the work of sticking winding, it is characterized in that: continued flow component R adopts piezo-resistance, and starting winding L 1 number of turn is 1300～2000 circles, and its line directly is 0.20～0.35mm, sticking winding L 2 numbers of turn are 10000～15000 circles, and its line directly is 0.07～0.12mm.
2, according to the contactor of claim 1, it is characterized in that: described startup winding L 1 number of turn is 1600～1700 circles, and line directly is 0.29～0.32mm, and sticking winding L 2 numbers of turn are 12000～13000 circles, and line directly is 0.07～0.09mm.
