Field of the Invention The present invention relates to a drive device for driving an actuator for circuit breaker operation, for example, an Electro-Magnetic Force driving Actuator (EMFA), more specifically EMFA. In the circuit breaker control unit, a drive current supply block dedicated to supply a series of EMFA drive currents, for example, a forward drive current and a reverse drive current, and a forward drive supplied from the drive current supply block side to the EMFA side. Control circuit block that can control the EMFA to selectively generate forward or reverse linear motion (i.e., bidirectional linear motion) by switching the current and the reverse drive current>, <Management of the breaker control unit According to the present invention, the control circuit control block for controlling the switching pattern of the control circuit block, etc. is systematically arranged and provided. The EMFA is integrated with the EMFA by guiding the work of the integrated work unit to selectively generate optimized linear reciprocating motion (i.e., linear forward motion and linear reverse motion) under the control of the breaker control unit without any problems. Connected and deployed circuit breakers also relate to EMFA-driven devices that can be induced to exhibit optimized breaking performance.

In general, the breaker is mainly installed in the power transmission line or the power receiving end of the transmission line, and when there is no failure in the power system, it serves to open and close the normal current, and in the event of a failure such as a short circuit, This plays a very important role in protecting power systems and power equipment (loads).

Of course, such a circuit breaker is generally connected with an actuator for detailed operation of the opening and closing state of the circuit breaker, and in this situation, since the overall opening and closing operation of the circuit breaker is made in conjunction with the movement of the actuator, the actuator is of any quality The main question is whether or not it maintains a critical factor in determining the overall operating performance of the circuit breaker.

Perhaps of course, the applicant, who has been in the field of electric / electronic for many years, can recognize and grasp the importance of such an actuator faster than anyone. As a result, Korean Patent No. 10-668923 (name: Manipulator using electromagnetic force), Korean Patent Registration No. 10-641025 (name: manipulator using electromagnetic force and breaker using the same), Korean Patent No. 10-718927 (name: manipulator using electromagnetic force and breaker using the same) disclosed in detail An improved performance actuator, i.e., an electro-magnetic actuator (EMFA) has been developed and distributed.

Of course, the EMFA developed / filed and registered by the applicant is different from conventional actuators such as Permanent Magnetic Actuators (PMAs), which are based on the <current magnetic field of the permanent magnet> and <coil current density. By the interlocking action of the electromagnetic repulsive force, the movable element having the coil integrally generates a series of linear reciprocating motions (i.e., forward linear motion and reverse linear motion), thereby connecting a driven element (e.g., a circuit breaker) connected to itself. Because it takes a very unique mechanism to operate the EMFA, in order to operate this EMFA in an optimized state, a series of bidirectional control currents (i.e., a forward control current and a reverse control current) may be selectively applied. EMFA only, which can be controlled to allow the mover with integral body to generate selective linear reciprocating motions (i.e., forward and reverse linear motions). The placement of such devices are necessarily required.

Accordingly, an object of the present invention is to supply a drive current exclusively for supplying a series of EMFA drive currents, for example, forward drive current and reverse drive current, into a breaker control actuator, for example, a breaker control unit that manages an EMFA. Block>, <drive current supply direction and reverse drive current supplied from the drive current supply block side to the EMFA side, EMFA can selectively change the forward or reverse linear motion (i.e., bidirectional linear motion) according to the situation. Control circuit block that can be controlled to be generated> and <control circuit control block for controlling the switching pattern of the control circuit block according to the management of the circuit breaker control unit>, etc. systematically arranged and provided, Optimized linear reciprocating motion (i.e., linear forward direction) under the control of the breaker control unit without any problems. By the guide to selectively cause the same straight line and reverse motion), connected to the EMFA · the circuit breaker is arranged to derive to also indicate the optimal blocking performance.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, the present invention is installed in a circuit breaker control unit that controls the operation of the circuit breaker, and a net for inducing linear reciprocation of an electromagnetic force actuator (EMFA) connected to the circuit breaker. An EMFA driving current supply module for supplying a directional driving current and a reverse driving current to the EMFA side, and disposed on a current supply path between the EMFA driving current supply module and the EMFA, and the EMFA from the EMFA driving current supply module side; By switching the supply pattern of the forward driving current and the reverse driving current supplied to the side, the EMFA selects the forward linear movement or the reverse linear movement according to the change of the supply pattern of the forward driving current or the reverse driving current. An EMFA drive control driver to control the power generation, and the EMFA drive control driver and the electric And a driver control module for controlling a switching pattern of the EMFA driving control driver by applying a control current to the EMFA driving control driver according to a control signal output from the circuit breaker control unit. An EMFA drive device is disclosed.

In the present invention, a breaker control actuator, for example, a drive current supply block for exclusively supplying a series of EMFA drive currents, for example, forward drive currents and reverse drive currents, into a breaker control unit that manages EMFAs. By switching the forward drive current and the reverse drive current supplied from the drive current supply block side to the EMFA side, the EMFA is controlled to selectively generate the forward or reverse linear motion (ie, bidirectional linear motion) according to the situation. Control circuit block>, <control circuit control block for controlling the switching pattern of the control circuit block> and the like according to the management of the circuit breaker control unit, etc. are systematically arranged and provided. The associated <operator with coil integrally> is optimized linear reciprocating motion (i.e., under the control of the breaker control unit) without any problems. Able to selectively cause the line the forward movement and the reverse movement line) is, the end, connected to the EMFA · breaker arrangement it is possible to also indicate the optimal blocking performance.

Hereinafter, with reference to the accompanying drawings, it will be described in more detail EMFA drive device according to the present invention.

As shown in Fig. 1, under the system of the present invention, the breaker 2 cuts the fault current when a fault such as a short circuit occurs in the state of being installed at the power transmission end or the power receiving end of the power transmission line, thereby preventing the power device ( 1: that is, to protect the load). Of course, the breaker 2 is connected to the EMFA 100 previously developed by the present applicant is connected and arranged, it is to operate in detail the opening and closing state of the breaker (2).

At this time, as shown in the figure, the EMFA 100 includes a fixed iron core 110, the fixed iron core 110 is made of a magnetic material, thereby forming the overall outline of the EMFA (100). In this case, the fixed iron core 110 is formed with two passages 111 penetrating in the front-rear direction while having a predetermined length in the vertical direction, and the passage 111 is formed in the middle of the fixed iron core 110 by a series of The intermediate wall 112 is formed and defined.

Here, the outer main permanent magnet 200 and the inner main permanent magnet 300 is further installed on both wall surfaces of each passage 111 formed in the fixed iron core 110, the outer main permanent magnet 200 and the inner main permanent Between the magnets 300, while the intermediate wall 112 is interposed therebetween, the movable element 400 which can linearly reciprocate in the longitudinal direction (up and down direction in the figure) of the passage 111 is provided. In this case, a series of coils 410 are wound around the mover 400 in a direction orthogonal to the outer main permanent magnet 200 and the inner main permanent magnet 300.

In this situation, when the driving current in the forward or reverse direction is supplied to the coil 410, a series of magnetic fields and electric fields are formed around the outer and inner main permanent magnets 200 and 300 and the coil 410. As a result, the electromagnetic force in one direction (that is, the forward direction or the reverse direction) is strongly applied to the mover 400 depending on the situation.

Of course, under such a situation that a series of electromagnetic force is applied, the mover 400 is a straight forward or reverse direction of the linear movement quickly proceeds, after all, the breaker connected to the EMFA 100 is a straight line of the mover 410 In accordance with the reciprocating motion, by achieving a series of opening and closing state, it is possible to normally perform the normal current supply function or the fault current blocking function given to the self.

For reference, the detailed configuration and detailed operation of the remaining elements provided in the EMFA 100 is disclosed in detail in the above-mentioned National Patent No. 10-718927 (name: manipulator using electromagnetic force and breaker using the same), For convenience, the description thereof will be omitted.

As such, the EMFA 100 employed in the present invention is integrated with the <coil 410 by the interlocking action of the <magnetic field by the permanent magnet (200,300)> and <electron repulsion force by the current density of the coil 410>. Since the mover 400 has a very unique mechanism for operating the circuit breaker 2 connected to itself by causing a series of linear reciprocating motions (i.e., forward linear motions and reverse linear motions), In order to operate the EMFA 100 in an optimized state, a series of two-way control currents (that is, forward control currents and reverse control currents) may be selectively applied to the movable element having the coil 410 integrally ( It is essentially necessary to place an EMFA-only driving device that can be controlled so as to allow a whole to generate selective linear reciprocation (i.e. forward and reverse linear movements).

At this time, as shown in Figure 1, EMFA drive device 20 according to the present invention that can satisfy the above-mentioned various difficult conditions is a structure installed in the circuit breaker control unit 10 for the overall control of the operation of the circuit breaker (2) In the state taken, it is controlled by the breaker drive control module 11 belonging to this breaker control unit (10).

When the required event> occurs, the breaker drive control module 11 immediately inputs a control signal to the EMFA drive device 20 of the present invention, whereby the EMFA 100 controls the EMFA drive device 20.

That is, the forward drive current and the reverse drive current for inducing the forward linear motion and the reverse linear motion are converted / generated, and the generated forward drive current and the reverse drive current are dedicated to the EMFA 100 side. It will serve to supply.

In this case, as shown in FIG. 3, the EMFA driving current supply module 30 uses a noise filter 31 for attenuating noise of power supplied from the AC power source 3 side, and the noise filter 31. DC converter 32 for converting the AC power that has passed into DC power, and the capacitor 33 for outputting the stabilized DC power to the EMFA drive control driver 40 after smoothing and stabilizing the converted power to DC.
