Abstract
The AC electromagnet includes work coil, start coil, pull rod for moving iron core and moving iron core to act synchronously, micro switch and capacitor. The parallel coil and capacitor produce resonance to maintain attraction force and consume least electric energy to save energy. The utility model is particularly suitable for a traction type electro-magnet.
Description
A kind of electromagnet, particularly a kind of energy-conservation, AC solenoid for valve.
Patent Office of the People's Republic of China announced a kind of energy-saving electromagnet on October 25th, 1989, notification number is CN 2046675U, though this electromagnet is divided into two coils with the coil of general electromagnet, one is that actuating coil, one are actuating coil, behind electromagnetic actuation, actuating coil is disconnected, only allow actuating coil work, reached certain energy-conservation purpose, but still in actuating coil, be connected with bigger electric current behind the electromagnetic actuation, could keep necessary suction, therefore, this energy-saving electromagnet of being announced still has the big shortcoming of consumed power.
Task of the present utility model is to propose the higher electromagnet of a kind of energy-saving efficiency.
The technical scheme of finishing the utility model task is the capacitor in the two ends of an actuating coil suitable capacity in parallel, actuating coil and actuating coil while incoming transport when power connection, two in the same way the coil of coiling produce enough big suction the moving iron core of electromagnet moved and adhesive, moment in adhesive disconnects actuating coil by a sensitive switch, simultaneously the capacitor of suitable capacity is inserted, make it and the actuating coil parallel connection, at this moment the inductance of actuating coil and electric capacity produce resonance, continue to make electromagnet to keep certain suction, and the electric energy minimum that power supply is supplied with has reached the purpose that improves energy-saving efficiency.
Fig. 1 is the electrical schematic diagram of the utility model embodiment.
L
2Be actuating coil, L
1Be actuating coil, C is a capacitor, K
2Be sensitive switch, K
1Be operating switch, as operating switch K
1During connection, identical around to actuating coil L
1With actuating coil L
2All there is electric current to flow through, produces enough suction so that electromagnetic actuation, sensitive switch K behind electromagnetic actuation
2Disconnect actuating coil L
2, and make capacitor C place in circuit and actuating coil L
1Be together in parallel, form antiresonant circuit, during parallel resonance, the energy that power supply is supplied with is very little.
Fig. 2 is the structural representation of the utility model embodiment, the 1st, capacitor, the 2nd, actuating coil, the 3rd, actuating coil, the 4th, sensitive switch, the 5th, pull bar, the 6th, moving iron core, actuating coil and actuating coil are around to identical, and the normally-closed contact of sensitive switch makes actuating coil 2 and actuating coil 3 be state in parallel at ordinary times, has suitable suction to guarantee electromagnet.After moving iron core 6 was by adhesive, the pull bar 5 that is connected with moving iron core 6 made sensitive switch 4 actions, and normally-closed contact disconnects, normally opened contact is connected, and at this moment actuating coil 3 is disconnected, capacitor 1 inserts and actuating coil 2 parallel connections.
The capacitor volume that the utility model adopted can be selected according to the size of different winding inductance quantities.
The utility model is applicable to various alternating electromagnets, A.C. contactor, and the alternating electromagnet of particularly traction series, electric energy can reach 80%～90%.
