Abstract
The utility model relates to an electronic AC contactor, which mainly comprises a shell, a contact system and an electromagnetic system; a loop of the electromagnetic system comprises a pick-up loop and a holding loop; the pick-up loop and the holding loop are connected with a loop direct current power supply control circuit. The utility model has the advantages that: the loop is supplied with direct current, the pick-up current of the pick-up loop is great, the holding current of the holding loop is less, thereby the breaking ability of the contact is high, the energy consumption is saved, the voltage control rage is wide and the performance is reliable.
Description
Affiliated technical field
The utility model relates to a kind of contactor, and particularly a kind of is the A.C. contactor of main composition with housing, contact system and electromagnetic system.
Background technology
Existing A.C. contactor is provided with a solenoid in its electromagnetic system, be by AC-powered.The solenoid of this structure exists certain deficiency, and it is bigger to be mainly reflected in power consumption, and coil control voltage range is narrower.
Summary of the invention
The purpose of this utility model provides a kind of electronic type A.C. contactor that can increase coil control voltage range and can cut down the consumption of energy.
The technical solution of the utility model is: the utility model mainly is made up of housing, contact system and electromagnetic system, and the coil of its electromagnetic system is made up of pull-in winding and 2 coils of hold-in winding, and these 2 coils and coil direct current supply control circuit link.Can realize that by this coil direct current supply control circuit direct current energising work, pull-in winding outage and the hold-in winding of pull-in winding and hold-in winding continue the running of energising work.Because the required operating current of hold-in winding is little, thereby it is little to consume energy, simultaneously,, realized increase to coil control voltage range by to the parameter setting in the coil direct current supply control circuit.
The utility model has the advantages that coil control voltage range is wide, energy consumption is little, reliable operation, contact breaking capacity height.
Below in conjunction with accompanying drawing the utility model is further specified.
Description of drawings
Accompanying drawing is the utility model coil direct current supply control circuit figure.
Embodiment
With reference to the accompanying drawings, the main circuit annexation of the utility model coil direct current supply control circuit is: two outputs of the rectifier bridge that is made of diode D1-D4 constitute the hold-in winding DC loop with hold-in winding L2 and are connected, also constitute the pull-in winding DC loop with pull-in winding L1 simultaneously and be connected, the end of pull-in winding L1 is connected with the output of the delay switch circuit that is made of triode T1 and field boundary effect pipe T2.C1, C2, C3 are filter capacitor among the figure, and R3 is a divider resistance, and R1, R2, R5, R6 are current-limiting resistance; diode D5, D6 are used for the unidirectional conducting of electric current; diode D9, D10 are used for burning voltage, and resistance R 4, capacitor C 4 constitute delay circuit, and diode D7, D8 are used to protect field boundary effect pipe T2.
The course of work of the present utility model is as follows: when coil direct current supply control circuit is connected AC power, behind rectifying and wave-filtering, pull-in winding L1 and hold-in winding L2 switch on simultaneously, the contact action, major loop is connected, triode T1 time-delay conducting immediately also ends field boundary effect pipe T2, pull-in winding L1 outage, and hold-in winding L2 works on.When AC power disconnects, protection coil L2 outage, contact disconnects, the main circuit disjunction.Control reference voltage of the present utility model can reach 75-120%Us.
