Abstract
An energy-saving contactor comprises essentially a basal seat, and an arc-extinguishing chamber and a pedestal respectively arranged at the upper and the lower ends of the basal seat. A supporting element and a keeper of the contactor are positioned in the basal seat. Coils, a yoke iron without a shading ring, and a wide voltage power supply energy-saving module consisting of a push rod, a fixed contact, a moving contact, a reaction spring, a small seat and an automatically-operating electronic circuit board are positioned on the pedestal. The utility model has the advantages of reliable performance and excellent energy-saving effect due to the wide range of allowable working voltage of the contactor.
Description
The utility model relates to a kind of low-voltage electrical apparatus switch, and specifically a kind of have an energy-conservation contactor of wide voltage power supply.
Existing contactor is made of base, arc control device, pedestal mostly, and its magnetic system operation is divided into alternating current operation and dc operation.The alternating current operation system comprises coil and has the iron core of divided magnetic ring by the silicon steel sheet riveted, is typical inductive load.Its power factor is about 0.24-0.3, and each contactor power consumption is between several watts to tens watts; The dc operation system, the electromagnetic system volume ratio exchanges and will be twice, and not only unit product is a lot of with non-ferrous metals such as copper, aluminium, and separate unit product power consumption is than increasing 1-2 doubly with capacity alternating current operation contactor.In addition, the permission operating voltage range of contactor is 85%-110%, because operating voltage range is not wide, therefore often easily produces fault.
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of have wide voltage power supply and reliable operation, energy-conservation contactor.
The purpose of this utility model is achieved in that it mainly comprises pedestal and is placed on the pedestal, the arc control device of lower end, base, contact supporter and armature place in the pedestal, coil and not placing in the base with the yoke of divided magnetic ring, it is characterized in that on base, being provided with by push rod, fixed contact, moving contact, reaction spring, the wide voltage power supply energy-saving module that the automatic operation electronic circuit board that little seat and control coil direct-on-line starting and low pressure keep constitutes, moving contact links to each other with push rod, reaction spring places the push rod lower end, fixed contact places on the little seat, automatically the operation electronic circuit board is sleeved on the fixed contact, the push rod upper end is corresponding with the baffle plate on being located at armature, fixed contact and moving contact are as the control switch of operating electronic circuit automatically, and control voltage terminal links to each other with automatic operation electronic circuit board by lead-in wire with coil.When binding post did not obtain voltage, fixed contact and moving contact were in on-state.When binding post obtained voltage, coil got electric, attracted armature to drive the motion of contact supporter by yoke, made the main noddle on contactor closure.Meanwhile, the baffle plate on the armature is depressed push rod, makes fixed contact and moving contact disjunction, and coil is in the low pressure hold mode.
Above-mentioned automatic operation electronic circuit can be divided into alternating current operation electronic circuit and dc operation electronic circuit.The alternating current operation electronic circuit comprises two loops that constitute with the control voltage terminal, article one, be that control switch, rectification circuit through automatic operation electronic circuit is to contactor coil, to contactor coil, control switch and electric capacity, the resistance of operating electronic circuit automatically are in parallel through electric capacity, resistance, rectification circuit for another; Contactor coil is divided into starting winding and sticking winding in the dc operation electronic circuit, circuit also comprises two loops that constitute with the control voltage terminal, article one, warp operate automatically electronic circuit control switch, the starting winding to rectification circuit, to rectification circuit, the control switch of operating electronic circuit automatically is in parallel with the resistance that is connected in series, sticking winding through resistance, sticking winding, starting winding for another.
The utility model has the advantages that: the permission operating voltage range of contactor is wide, thereby reliable operation, and good energy-conserving effect.
Below in conjunction with accompanying drawing the utility model is explained.
Fig. 1 is the utility model structural representation.
Fig. 2 is the alternating current operation electronic-circuit diagram.
Fig. 3 is the dc operation electronic-circuit diagram.
By accompanying drawing as can be known, the utility model mainly comprises the arc control device 2 and base 3 of the pedestal 1 and pedestal 1 upper and lower end that is placed in.Contact supporter 16 and armature 17 place in the pedestal 1.Coil 5 and not with the yoke 4 of divided magnetic ring and by push rod 7, fixed contact 8, moving contact 9, reaction spring 10, little seat 11, operate the wide voltage power supply energy-saving module that electronic circuit board 12 constitutes automatically and place on the base 3.Wherein moving contact 9 links to each other with push rod 7, reaction spring 10 places push rod 7 lower ends, fixed contact 8 places on the little seat 11, automatically operation electronic circuit board 12 is sleeved on the fixed contact 8, push rod 7 upper ends are corresponding with the baffle plate 18 (baffle plate also can be located on the contact supporter) on being located at armature 17, fixed contact 8 and the control switch J of moving contact 9 as automatic operation electronic circuit
