Abstract
The utility model relates to an economizer comprising a substrate of a contactor, a drive coil and an electronic adapter. The drive coil that is enclosed in the substrate is formed by an actuating coil and a holding coil; and the actuating coil and the holding coil are communicated with the electronic adapter. When the economizer works, the electronic adapter cuts off power of the actuating coil and the power of the holding coil is switched on. Because the resistance of the holding coil is far greater than the resistance of the actuating coil, the current flowing through the holding coil is low and thus the power consumption is reduced correspondingly and the heat value is small, thereby achieving objectives that the energy is saved and the overheating of the coils can be avoided.
Description
Technical field
The utility model relates to a kind of electric elements, the specifically conservation measures of drive coil in a kind of electromagnetic type D.C. contactor.
Background technology,
Coil in the common contactor is not established energy-saving control device, and such setting not only power consumption is large, and reaches easily heating, and this not only directly affects the useful life of contactor, and past contact meeting causes the malfunction of contactor, even initiation fire.
The utility model content
In order to remedy the deficiency of contactor power consumption Da Yi heating, the utility model provides a kind of energy-saving appliance, and this energy-saving appliance adopts the enclosed construction of plastics covering and the method for electronic adapter, can not only realize energy-conservation more than 60 percent, and anti-dust performance is good, security maintenance-free.
The utility model solves the technical measures that its technical problem takes, energy-saving appliance is by the pedestal of contactor, drive coil and electronic adapter form, described drive coil is enclosed in the pedestal, drive coil is comprised of actuating coil and hold-in winding, actuating coil and hold-in winding are connected electronic adapter, described electronic adapter is by metal-oxide-semiconductor (field effect transistor), electric capacity, the compositions such as resistance, electronic adapter is installed in the housing of pedestal one side, by socket and actuating coil and hold-in winding connection, during work, at first connect the power supply of actuating coil, make the closing of contact, instantaneous in the closing of contact, come the conducting metal-oxide-semiconductor by the capacitor discharge in the electronic adapter, with electrical source exchange, cut off the power supply of actuating coil, connect simultaneously the power supply of hold-in winding, so after the closing of contact of contactor, switched on to the long-time closure of holding contact by hold-in winding, because the resistance of hold-in winding is far longer than the resistance of actuating coil, therefore the electric current by hold-in winding is also little, and power consumption is corresponding reducing also, the little caloric value of electric current by hold-in winding is also little, thereby reaches energy-conservation and avoid the overheated purpose of coil.
The beneficial effects of the utility model are that it is overheated to exempt from, good energy-conserving effect, compact conformation, security maintenance-free.
Description of drawings
Be described further the utility model is bright below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of energy-saving appliance;
Fig. 2 is the circuit diagram of energy-saving appliance.
Among the figure, 1. drive coil, 2. pedestal, 3. actuating coil, 4. hold-in winding, 5 electronic adapters, 6. housing.
Embodiment
In Fig. 1, drive coil 1 is enclosed in the pedestal 2, drive coil is comprised of actuating coil 3 and hold-in winding 4, actuating coil and hold-in winding are connected electronic adapter 5, described electronic adapter is comprised of metal-oxide-semiconductor (field effect transistor), electric capacity, resistance etc., electronic adapter is installed in the housing 6 of pedestal one side, by socket and actuating coil and hold-in winding connection.
In Fig. 2, electronic adapter 5 is connected respectively actuating coil 3 and hold-in winding 4.
