Abstract

The utility model discloses a noise-free relay consisting of a shell, an energy-saving operation breadboard, static and dynamic iron cores, a contactor, an electric coil and a return spring, which is characterized in that a corresponding electric coil control loop is provided. wherein, the input AC power is supplied to the coil through the diode commutation. The electric coil control provided in the utility model can realize a large instant current flow to the coil, which can reach the current of reliable operation and quickly goes into the direct current low-voltage operation, thereby avoiding the hysteresis and short circuit loss, reducing the energy consumption of the coil and realizing the power-saving and noise-free effect without using the short circuit ring. Being simple in structure, the utility model has a control manner similar to that of the traditional relay, that is, to operate with switch on and to release with switch off, thereby no change is necessary of the existing manner of connection when erecting for use, which can directly replace the traditional relay and be extensively applied in the automatic control field.

Description

Energy-conservation noiseless relay

Affiliated technical field

The utility model belongs to the relay in the low-voltage electrical apparatus field, refers in particular to a kind of energy-conservation noiseless relay.

Background technology

At present, widely used various relays, are needed in the coil to keep the adhesive of armature with bigger electric current, thereby have consumed no small energy during work by the solenoid adhesive armature.People have done many work for the energy consumption that reduces relay itself, a kind of " not having the consume latching relay " (ZL92220828 is disclosed as Chinese patent, stop), it has coil, iron core, contact and latching device, be characterized in that latching device is made of lock dog, pintle hook lock, swing arm and spring, it has changed the control method of traditional relay, but the relay of traditional energising adhesive, outage release type can not be compatible, thereby can not replace easily, thereby limited applying of they.

Summary of the invention

The purpose of this utility model is exactly the deficiency that has energy-saving relay now in order to overcome, and a kind of simple structure, reasonable is provided, and control method is consistent with traditional relay, replacement is easy to use, and the energy-conservation noiseless relay that can cut down the consumption of energy significantly.

For achieving the above object, the solution that the utility model is taked is: a kind of energy-conservation noiseless relay, have housing, energy-saving run wiring board, static iron core and moving iron core, contact, coil, back-moving spring, it is characterized in that also having the respective coil control loop, this coil control circuit is supplied with coil by input ac power through diode rectification and is constituted.

Because the coil control circuit of the utility model setting has been realized AC power and has supplied with coil through diode rectification that the immediate current of supplying with coil can reach the electric current of reliable adhesive more greatly, enters DC low-voltage after the coil adhesive rapidly and keeps.Because being in direct current keeps running status, just can remove magnetic hysteresis loss and short circuit loss from, the coil energy consumption also slightly descends simultaneously, reaches economize on electricity, muting effect, has saved short-circuited conducting sleeve.It is in when work, as long as in addition lessly in coil keep electric current, the reliable contact adhesive of dynamic and static iron core in the time of just can guaranteeing adhesive.The utility model simple structure, its control mode is the same with the control mode of traditional relay, promptly switch on adhesive, outage discharges, thereby when installing and using, do not need to change the present mode of connection, but the traditional relay of direct substitution uses, and can be widely used in automation field, implementation procedure control.

Description of drawings

Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.

Fig. 1 is the coil control circuit halfwave rectifier schematic diagram of embodiment one.

Fig. 2 is the coil control circuit full-wave rectification schematic diagram of embodiment two.

Embodiment

Referring to Fig. 1 or Fig. 2, a kind of energy-conservation noiseless relay, have housing, energy-saving run wiring board, static iron core and moving iron core, contact, coil J, back-moving spring, it is characterized in that also having the respective coil control loop, this coil control circuit is supplied with coil J by input ac power through diode D1, D2, D3, D4 rectification and is constituted.

Referring to Fig. 1 or Fig. 2, AC power is by diode D1, D2, D3, D4 halfwave rectifier or full-wave rectification, coil J gets, relay contact work, so the electromagnetic force that needs dc coil to produce will reduce many, thereby only need less direct current just can keep after making the coil adhesive, reduced the energy consumption of coil widely.

As shown in Figure 1, diode D3, D4 are fly-wheel diode, have overvoltage protection, afterflow effect.

In the utility model, have a groove in the centre of static iron core, make its magnetic pull be slightly less than the tension force that back-moving spring flicks moving iron core to moving iron core.Like this, the moving iron core in outage back can discharge under the effect of back-moving spring automatically.
