Abstract

A non-power-consuming contactor mainly composed of an electromagnet, a movable contact support frame (36), movable contacts (33), stationary contacts (34), and a locking module (7). The contactor utilizes the interaction between a sliding plate (8) and a locking piece (9) to enable an electromagnetic coil (2) to be energized instantaneously once such that the contactor is in a connection state, and upon being energized instantaneously once again, the contactor is placed in a break-off state. Thereby, the disadvantage of power consumption generated when a contactor electromagnet coil is operated with respect to electrical appliances can be effectively avoided, thus effectively reducing electrical energy consumption and noise pollution since the contactor operates silently.

Description

A new type of contactor that does not consume electricity

Technical field

The invention relates to a common control electrical appliance in industrial production, in particular to a novel contactor that does not consume electricity, and belongs to the field of low-voltage electrical appliances.

Background technique

There are many types of contactors, such as AC contactors, DC contactors, permanent magnet contactors, relays, etc., which are mainly used for frequently turning on and off circuits or control systems over long distances. In particular, AC contactors are used in the largest amount of control equipment. The contactor pulls a plurality of sets of contacts with an electromagnet. When the electromagnet is pulled in, the contacts are closed and the appliance is operated. On the contrary, the electromagnet loses power and the appliance stops working. That is to say, when the electrical appliance needs to work, the electromagnet must also be in a power consuming state.

It is well known that the role of an electromagnet in a contactor is simply to pull the contact closure. Other actions, such as release of the contact, stopping the operation of the appliance, etc., do not require an electromagnet to complete. Electromagnets remain energized for a long time with the operation of electrical appliances, which is a kind of unnecessary loss, which causes the power consumption of electromagnets. More than 99% of the electric energy is consumed in this unnecessary loss, which greatly wastes energy. And the electromagnetic coil is easily burned when it is in the holding state for a long time. And the noise generated by it is relatively large, directly polluting the environment.

In response to the above drawbacks, many experts and scholars at home and abroad have carried out a lot of research and improvement on this, especially in the aspect of power saving technology, which has experienced three stages of development, and some representative products have emerged:

The first stage: the representative product is the AC contactor power saver. It has three types: capacitor type, transformer type and duty cycle self-switching.

The second stage: the representative product is the AC contactor power-saving coil. The utility model has a double-winding power-saving coil type, a current limiting resistor type power-saving coil, a double-winding self-converting power-saving coil and a positioning magnetic conversion power-saving coil.

The third stage: power-saving AC contactor. It integrates the power-saving coil or transformer of the new power-saving system with the electromagnetic system of the AC contactor itself, reducing the cost of the new power-saving system.

The above new energy-saving products are all external facilities, which not only add a new set of auxiliary facilities outside the contactor, but also increase the cost of the product. Some also occupy the auxiliary contacts of the contactor and use the field control circuit. bring inconvenience. Some have also introduced electronic circuits, which increase the complexity of the product and generally have the effect of saving electricity and reducing noise.

Recently, a permanent magnet contactor has obvious advantages in terms of power saving, but it has many disadvantages such as low anti-interference ability, high operational reliability, poor safety, high cost, etc., so it is still on the market. Can not be widely accepted.

Summary of the invention

The present invention is a novel contactor that does not consume electricity in order to overcome the problem of large deadweight loss of the contactor and serious noise pollution. It enables the contactor to use electricity only once at the moment of turning on and off, and never consumes power when it is held.

The technical solution adopted by the present invention to solve the technical problem is that: at the bottom of the contactor housing, an electromagnetic coil and an iron core are sequentially installed, and an armature is installed in the middle portion, and a middle convex portion passes through the middle of the armature return spring and the iron core. The convex portions are respectively sleeved in the electromagnetic coil, and the upper side of the armature is connected with the movable contact support frame through the armature insert, and the movable contact is placed in the rectangular hole in the upper part of the movable contact support frame, corresponding to the movable contact On the outer casing part, a static contact is installed, and on one side of the upper cover, a locking module is installed, and on the locking module seat, a sliding plate, a locking piece, a torsion spring and a reset button are respectively arranged, and the lower part of the sliding plate is arranged. The horizontal protrusion is connected to the connection groove on the lower side of the movable contact support frame.

Electromagnetic coil, iron core, armature, moving contact support frame, moving contact, static contact, return spring, etc., are the original components of the contactor, and control the movement by controlling the energetic and non-electrical state of the electromagnetic coil. The closing and opening states of the contacts and the stationary contacts are used to control the operation or stop of the electric appliance.

The original contactor maintains the appliance by supplying power to the solenoid and keeping it in a holding state. The invention controls the closing or opening of the movable contact and the stationary contact by the up and down displacement of the sliding plate provided in the locking module on one side of the contactor, and thereby controls the operation or the stop of the electric appliance. That is to say, the present invention can realize the instantaneous energization of the electromagnetic coil once by the interaction of the sliding plate and the locking piece in the newly-locked module without changing the structure of the original contactor, and the contactor enters. When the state is on, the appliance is operated; the electromagnetic coil is energized once again, and the contactor can enter the disconnection state, and the electrical appliance stops working. That is to say, when the electric appliance is used for electric work, the electromagnetic coil does not consume electricity, thus completely eradicating the drawback that the contactor consumes electricity when working with the electric appliance, and the power saving effect is very obvious, and the electromagnetic When the coil is in operation, the coil is in a power-off state, so that the electromagnetic coil itself does not generate heat and is not burnt, and its service life will be forever, and its noise must be zero.

The movable contact support frame (36) and the armature (5) are moved downward to compress the armature return spring (4) for energy storage. At the same time, the movable contact support frame (36) pulls the horizontal protrusion (45) disposed at the lower portion of the sliding plate (8) through the movable contact support groove (31), so that the sliding plate (8) is displaced downward, and is set. The vertical projection (15) in the middle of the right side of the sliding plate (8) is also displaced downward at the same time. When it touches the locking piece to act on the inclined surface (17) and continues to move downward, the locking piece (9) supports the column with the locking piece. The center of (28) is the center of the circle. Start the rotation to the left and turn the mounting ear (10) to start the energy storage of the torsion spring (11). When the right side of the action bevel (17) slides over the left side of the vertical projection (15), the locking piece (9) loses the support of the vertical projection (15), and then the leftward rotational motion is stopped. When the vertical projection (15) is moved down to the lower side of the right end of the action bevel (17), the locking piece (9) starts to make a rightward return movement under the action of the torsion spring (11), and the damping bend is disposed at the lower portion thereof. The hook (18) just hits the left side of the downwardly moving vertical projection, and the locking piece (9) stops the return movement to the right. The vertical projection (15) starts to move up under the push of the armature return spring (4), and then rests on the locking surface (39), stops the upward displacement movement, and defines the movable contact through the sliding plate (8). The upward displacement of the support frame (36) keeps the movable contact (33) and the static contact (34) in a closed state, and continues to work with the electric appliance, thereby realizing the purpose of unnecessary power consumption of the electromagnetic coil (2) when the electric appliance is working. Of course, no power consumption will be generated and the purpose of power saving will be achieved. Moreover, since the electromagnetic coil has no current passing during the operation of the electric appliance, the contactor generates no noise and exhibits a zero noise state.

When the electrical appliance needs to stop working, the electromagnetic coil (2) is energized once, and the armature (5) is sucked by the iron core (3), and the moving contact support frame (36) and the sliding plate (8) are driven downward. The displacement, vertical projection (15) is also displaced downward. When the vertical height of the vertical protrusion (15) moves to a height lower than the vertical line of the return slope (25), the right side of the return slope (25) on the locking piece (9) is separated from the vertical protrusion (15). Restricted, under the action of the torsion spring (11), it began to move to the right again. When the locking piece (9) moves to the right to a certain extent, the setting On the upper side of the limiter arm (13) at the upper right portion of the locking piece (9), the lower side of the limit post (14) is abutted, and the locking piece (9) is stopped from moving to the right. At this time, the vertical protrusion (15) has completely deviated from the limit of the locking surface (39), just under the return slope (25), and is moved upward by the armature return spring (4), vertical. The projection (15) returns from the underside of the locking piece to the initial state. Of course, the sliding plate (8), the movable contact support frame (36), the movable contact (33), and the armature (5) are also returned to the initial state at the same time. The movable contact (33) is out of contact with the stationary contact (34), the circuit is disconnected, and the appliance is stopped, completing the function of the contactor.

It can be seen from the whole working process of a new type of contactor that does not consume electricity that its electromagnetic coil (2) is only used once every moment when the circuit is turned on and off, and is in a non-power state for the rest of the time. No matter how long it takes to work with electrical appliances, it does not consume electrical energy, and truly achieves the purpose of saving electricity.

The magnetic coil (2) is always in the power-off state when the electric appliance is working, and the electromagnet system is in a non-suction state, so the contactor generates no noise and exhibits a zero noise state.

Although the electromagnetic current consumption of the contactor electromagnetic coil is only one hundred and ten milliamperes, the on-site quantity of hundreds of millions of units in the country is enough to consume tens of billions of kilowatts of electricity every year, consuming 10 million tons of standard coal, which is a waste that cannot be underestimated. . Therefore, the invention and implementation of a new type of contactor that does not consume electricity will have positive significance in terms of energy conservation and environmental protection.

The embodiments described above are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, which is made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention. Various modifications and improvements are intended to fall within the scope of the invention as defined by the appended claims.
