Description

[0001] CIRCUIT BREAKER WITH INSTANTANEOUS TRIP OF PCB TYPE [0002]

More particularly, the present invention relates to a circuit breaker having a function of instantaneous non-instantaneous detection, and more particularly, to a circuit breaker having a function of detecting an overload by a ZCT element, The present invention relates to a circuit breaker having a non-visual instantaneous detection function capable of blocking a short circuit or an overload by simultaneously configuring a sensor.

Methods for measuring the current include devices and methods for measuring current in a wide variety of ways such as a current transformer, a shunt, a Hall sensor, and a Rogowski coil.

The most common current measurement method used to measure load current and fault current in power devices such as conventional switchboards and various high-voltage switchgears is to use a CT coil wound around an iron core.

However, since CT is manufactured using an iron core, if the current measurement range is increased according to the physical characteristics (iron interferences caused by inter-electron induction phenomenon and hysteresis) of the material itself, the iron core may deviate from the measurement error, There is a difficult problem.

In order to prevent saturation in CT, it is necessary to use a high-grade material or to increase the amount of iron core. However, when CT is used in excess of a predetermined amount, it is difficult to produce CT. The user has excessively increased volume for storing CT, .

Also, in order to be used in an electric device such as a circuit breaker for wiring, three current transformers (CT) and a zero phase sequence current transformer (ZCT) are also referred to as ZCT Quot; integrated video transformer " is known.

It is known that a commonly used ZCT is a circular donut shape (annular shape), but it has a track shape instead of a circular shape in order to reduce the size of the device in a current transformer integral type video current transformer.

The conventional transformer integral type current transformer can reduce the volume by integrating the current transformer and the current transformer in the main case.

The ELCB (Earth Leakage Circuit Breaker) is an assembly of an opening / closing mechanism, a trip device, and the like integrally in an insulating container. The electric circuit in the energized state can be opened or closed manually or electrically, It means to cut off the current automatically when it occurs.

These leakage circuit breakers are used for the purpose of preventing electric shock and electric fire caused by electric leakage in a low voltage circuit of less than 600V AC.

The earth leakage breaker includes a printed circuit board, a mechanical part for mechanically opening and closing the electrical circuit, a soffit for extinguishing an arc generated when the electrical circuit breaks off, a test switch for testing whether the electrical circuit breaker is normally operated, or a short circuit trip.

A back side type (COB type), a resistor, a capacitor, and a thyristor (SCR) are mounted on the printed circuit board.

However, in the conventional circuit breaker, components such as an IC (Back Side Type), a resistor, a capacitor, a thyristor (SCR), and the like are disposed on a printed circuit board, .

In this case, due to the mechanical structure narrowness of the earth leakage breaker, there is a limit to develop an earth leakage breaker which can additionally introduce a CT element in addition to ZCT to block the leakage or overload.

Specifically, as shown in FIG. 1, it is necessary to secure a considerable space. In the conventional case, since the size of the CT element is made to be the same size as that of the ZCT element (that is, The ZCT element and the CT element can not be simultaneously formed inside the case of the earth leakage breaker.

For example, since the ZCT device thickness is 1 cm and the CT device thickness is 1 cm x 2, a space for mounting a total thickness of about 3 cm is required.

That is, as shown in FIG. 1, since the distance from the PCB 30, in which the conventional ZCT device is formed, to the terminal 30 to which the wire 20 is connected is 2.3 cm, It is impossible to secure it.

Accordingly, in order to solve the above-described problems, the present invention provides a ZCT element, a fish-less type air-core coil sensor or a fish-core type ZCT element capable of detecting an overload and a fish- And to provide a circuit breaker having a non-visual instantaneous detection function capable of blocking an overload.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a circuit breaker having a function of instantaneous non-visual instantaneous detection according to the present invention will be described in detail.

Currently, the most common earth leakage breaker is ZCT, and there is a shunt or busbar through ZCT.

Particularly, since the mechanical structure is complicated, the space is narrow and the wire penetrates into the central hole of the ZCT, so that it is very tight and narrow.

Therefore, it is not possible to introduce a CT element for detecting an overload, and an additional function other than the function of the earth leakage breaker can not be performed.

However, according to the present invention, it is possible to provide an installation configuration in a narrow space by providing a ZCT element, a fish-less type air-core coil sensor capable of detecting an overload, a fish-core type ZCT element and a fish- .

Therefore, if a case is not needed or if necessary, a conventional ZCT element case size of 2 cm (width) x 2.5 cm (length) x 1 cm (thickness) is 1.5 cm (width) x 2.3 cm (length) x 0.1 cm It is possible to provide a synergistic effect that can overcome the limit of the space that can be mounted according to the complicated structure of the circuit breaker.

Preferably, the PCB of the circuit breaker of the present invention includes a PCB core type ZCT device and a CCD sensor, and the PCB may be slim with a width of 1.5 cm or less, a length of 2.3 cm or less, and a thickness of 0.1 cm or less do.

FIG. 2 is a schematic block diagram of a circuit breaker having a function of instantaneous non-visual sensing according to an embodiment of the present invention, and FIG. 3 is a schematic block diagram of a circuit breaker having a function of instantaneous non-visual instant sensing according to another embodiment.

2, the circuit breaker having the function of instantaneous non-visual instantaneous detection of the present invention mainly includes a ZCT element 1000, a fish body type 1 air core coil sensor 1500, a fish body type 2 air core coil sensor 2000, A COB-IC circuit unit 3000, a trip coil 4000, a trip coil switch 5000, and a main PCB board 7000.

At this time, the mechanical structure of the earth leakage breaker other than the above-mentioned construction means is a general technology, and a detailed description will be omitted.

The ZCT device 1000 senses a leakage current of the first wire L1 passing through the through hole and performs a function of transmitting a detection signal to the COB-IC circuit unit.

As shown in FIG. 2, the ZCT element generally has a through-hole formed at the center thereof. The coil pattern is formed along the circumference of the through-hole to penetrate the through-hole to detect a fault current such as a ground fault or an electric shock. .

The FCCB air-core coil sensor 1500 is formed as a printed circuit board on one side of the hole 7100 formed in the main PCB board 7000 so that one side thereof is opened to sense the overload current of the first electric wire L1 .

In addition, the PCB 230 may be formed of a printed circuit board having one side opened to sense the overload current of the second wire L2 on the other side of the hole 7100 formed in the main PCB board 7000 .

The COB-IC circuit unit 3000 is formed on the main PCB board 5000. The COB-IC circuit unit 3000 detects a leakage current provided from the ZCT device 1000 and provides a trip signal to the trip coil when a leakage current is generated, A COB IC, a resistor, a condenser, and a thyristor are provided in order to detect a current provided from at least one of the air core coil sensor 1500 and the fishbee type 2 air core coil sensor 2000 to provide a trip signal to the trip coil when an overload current is generated And integrated on a printed circuit board.

It is a conventional technique to provide a trip signal to the creep coil when the leakage current occurs in the COB-IC circuit unit or to provide a trip signal to the trip coil when an overload current is generated. Therefore, even if a detailed description is omitted, You will understand.

At this time, when the trip signal is acquired from the COB-IC circuit unit 3000, the trip coil 4000 functions to shut off the power by opening the trip coil switch 5000. The trip coil switch 5000 switches the trip coil So that the power supply of the first wire L1 and the second wire L2 is cut off.

If necessary, at least any one of the above-mentioned fish-eye type 1 air-core coil sensor 1500 and the fish-eye type 2 air-core coil sensor 2000 is formed around the hole.

That is, if necessary, the air-core coil sensor is not formed in two but is formed as one and is formed on the printed circuit board so that the overload current can be sensed.

The configuration of the circuit breaker according to an embodiment of the present invention is applied in a state in which a space is secured in the case of the circuit breaker, that is, a space in which an air core coil sensor for sensing an overload current is secured, It may be disadvantageous.

Accordingly, since it may be difficult to apply to a ready-made product, it can be solved by providing it in the form of a file fee.

On the other hand, in the case of the above-mentioned Fishby Brothers 1 air core coil sensor and Fishby Brothers 2 air core coil sensor,

Are symmetrical with respect to each other, and one side is opened.

That is, the first air-core coil sensor and the second air-core coil sensor have a shape symmetrical with respect to each other, and a characteristic feature thereof is that one side is open.

Since the one side is open, it can be formed as a semi-circular air-core coil instead of a circular air-core coil, thereby solving the problem of space narrowness.

More specifically, as shown in FIG. 2 or FIG. 4, the fish-eye type 1 air-core coil sensor 1500 and the fish-eye type 2 air-core coil sensor 2000 are configured to face each other.

At this time, in the case of mutually opposing shapes, the first and second electric wires must be spaced apart from the sensor device by a certain distance, A barrier rib 6000 (barrier) is formed between the above-mentioned fiber optic bifurcated first and second air core coil sensors 1500 and 2000, and the first and second wires are spaced apart from each other by a predetermined distance.

At this time,

And is formed when the fiber optic brother 1 air core coil sensor and the fish body brother 2 air core coil sensor face each other.

According to another embodiment, as shown in FIG. 3 or FIG. 5, the Fishby-brother type 1 air-core coil sensor 1500 and the Fishby-type brother 2 air-core coil sensor 2000 are installed in the same shape as each other.

It is not necessary to provide the barrier ribs if they have the same shape.

On the other hand, as shown in FIG. 6, the Fishby-type single-core coil sensor 1500 and the Fishby-type double-core air-core coil sensor 2000 are formed around the hole 7100 formed in the main PCB board 7000.

Then, the ZCT element 1000 is formed on the upper side of the above-mentioned fish-eye type air-core coil sensor 1500 and the fish-eye type two air-core coil sensor 2000.

According to the above configuration, it is possible to provide a synergistic effect that can solve the conventional narrow space problem.

In addition, a ZCT element, a fish-less type air-core coil sensor or a fishbone core type ZCT element capable of detecting an overload, and a fish-type air-core coil sensor capable of detecting an overload can be simultaneously configured in a small- Are integrated into the PCB, which is a printed circuit board, to provide an effect of enhancing the humidity-resistant characteristic and the reliability of the product performance.

In addition, the coil winding operation can be eliminated by constituting the ZCT element having the PCB core structure, the PCB non-core type coil sensor having the PCB structure, and the COB-IC circuit portion having the PCB structure in the circuit breaker, As integration with phosphorus is enhanced, it is possible to improve the characteristics of moisture resistance and reliability of product performance. By integrating various analog parts, it is possible to simplify the circuit work process and to provide mass productivity of products.

In addition, since it is provided in the form of a personal computer board, it is possible to reduce the space by reducing the size, thereby providing a cost saving effect.

Further, by eliminating the conventional coil winding operation, it is possible to make the electric characteristics constant (uniform) and to provide an effect of enhancing the affinity of the finished product.

FIG. 7 is a schematic block diagram of a circuit breaker having a function of instantaneous non-visual instantaneous detection according to an embodiment of the present invention; FIG.

As shown in Fig. 7, in the case of this case, the ZCT element and the air-core coil sensor are configured in the form of a PCB. In the case of a short circuit or an overload And to provide a circuit breaker having a function of instantaneous non-visual detection capable of interrupting this.

In order to provide the function as described above, the circuit breaker having the non-

A fiber optic ZCT device 1000a for detecting a leakage current of the first electric wire L1 passing through the through hole and transmitting a detection signal to the COB-IC circuit part,

The first PCB L1 is formed on the upper side or the lower side of the PCB type ZCT device 1000c and has one side opened to sense the overload current of the first line L1 at one side of the hole 7100a formed in the main PCB board 7000a A CCD sensor 1500a formed of a circuit board,

The other end of the second bus line L2 is connected to the other end of the hole 7100a formed in the main PCB board 7000a so as to detect an overload current of the second wire L2. A sensor assembly 2000a of the air core type formed by a substrate,

A leakage current provided from the ZCT device 1000 is detected to provide a trip signal to the trip coil when a leakage current is generated or at least one of the fishbaby brother 1 core air coil sensor 1500a and the Fishbys Brother 2 core air coil sensor 2000a In order to provide a trip signal to the trip coil when an overload current is generated by detecting the current provided from the above, a main board (not shown) having a COB-IC circuit unit 3000a in which a COB IC, a resistor, a condenser, and a thyristor are integrated on a printed circuit board 7000a,

At least any one of the above-mentioned fish-eye type air-core coil sensor 1500a and the fish-body type two-core coil sensor 2000a is formed around the hole.

More specifically, a PCB 1b air core coil sensor (not shown) formed on a printed circuit board such that one side thereof is opened to sense an overload current of the first wire L1 at one side of the hole 7100a formed in the main PCB board 7000a 1500b are formed on the other side of the hole 7100a formed in the main PCB board 7000a so as to detect the overload current of the second wire L2, 2000a.

Then, the PCB type ZCT device 1000a is formed on the upper side of the above-mentioned one-core type of the coaxial coil sensor 1500a and the two-core type of coercive force sensor 2000a.

At this time, if necessary, at least any one of the above-mentioned FishBee type 1 air core coil sensor 1500a and the Fishbys Brother 2 air core coil sensor 2000a is formed around the hole.

Thus, if the space required in one embodiment is A and the space required in the example is B, B < A.

In particular, with the above construction, the length (length) is reduced as compared with the embodiment, thereby providing a slim slim type mounting to the circuit breaker to mount various components.

For example, if a case is not needed, or if a case is needed, then a case size of 1.5 cm (horizontal) x 1.9 cm (vertical) x 2.3 cm (length) x 0.1 cm (thickness) ) x 0.1 cm (thickness).

That is, since the vertical length can be further reduced to 0.4 cm or more and the thickness to 0.1 cm or less, sufficient space can be provided in the circuit breaker.

The above-mentioned difference of the vertical length of 0.4 cm and the reduction of the thickness from 1 cm to 0.1 cm or less are complicated and provide a considerable space securing advantage in the case of a circuit breaker in which various various components are mounted.

In the conventional case, the size of the CT element is the same as that of the ZCT element, and one or two of the ZCT elements have the same size as the ZCT element. There is a structural problem that the ZCT element and the CT element can not be simultaneously formed inside the case of the circuit breaker.

For example, since the ZCT device thickness is 1 cm and the CT device thickness is 1 cm x 2, a space for mounting a total thickness of about 3 cm is required.

However, in the case of the ultra-slim device of the present invention, the size becomes 0.1 cm, in particular, the thickness becomes 0.1 cm, thereby securing a space for simultaneously configuring the CT devices.

For example, as shown in FIG. 1, since the distance from the PCB 30, in which the conventional ZCT device is formed, to the terminal 30 to which the wire 20 is connected is 2.3 cm, It is impossible to secure space to do so.

In summary, according to the present invention, it is possible to overcome the spatial limitations by making a ZCT element having a PCB core structure, a PCB non-core type coil sensor having a PCB structure, and a COB-IC circuit portion having a PCB structure, It provides scalability and applicability that can be applied.

In other words, it is possible to overcome the limitation of the space that can be mounted according to the complicated structure of the circuit breaker by being able to be slim, so that various devices can be introduced into the circuit breaker, so that not only the leakage current but also the function of cutting off the overcurrent can be introduced To provide a synergistic effect.

Meanwhile, in the circuit breaker of the present invention,

A normal circuit breaker, and a leakage current circuit breaker.

That is, it can be provided in a slim form to various kinds of circuit breakers.

FIG. 8 is a perspective view showing that layers of the PCB-type ZCT device 1000a of the circuit breaker having the function of instantaneous non-visual sensing according to the embodiment of the present invention are laminated, FIG. 9 is a perspective view of the PCB- And each of the layers of the fiber-optic-type two-core-coil sensor 2000a are stacked.

As shown in Fig. 8, the above-mentioned semiconductor chip type ZCT device 1000a includes:

An upper coil pattern forming layer 100 formed of a non-magnetic material and having a plurality of coil patterns 120 connected to each other via a via hole 110 alternately from the upper side to the lower side and from the lower side to the upper side;

A through hole layer 200 which is formed below the upper coil pattern forming layer and is formed horizontally on both sides of the central core layer and has a plurality of via holes 210 of the same size at the positions of the via holes 110, and;

A center core layer 300 formed of a core material between the through holes;

A plurality of coil patterns 420 are formed on the lower side of the through hole layer and the central core layer and are formed of a nonmagnetic material and are connected alternately from the upper side to the lower side and from the lower side to the upper side via a plurality of via holes 410 And a lower coil pattern forming layer (400).

The upper coil pattern forming layer 100 is formed of a nonmagnetic material and a plurality of coil patterns 120 connected to the lower coil pattern via the via hole 110 alternately from the lower side to the upper side are formed.

The through hole layer 200 is positioned below the upper coil pattern forming layer, and two holes are formed horizontally on both sides of the central core layer.

At this time, when viewed perpendicularly to the position of the via hole 110, a plurality of via holes 210 having the same size are formed.

At this time, the center core layer 300 is formed of the core material between the through holes.

Then, the lower coil pattern forming layer 400 is positioned below the through-hole layer and the central core layer, and is formed into a non-magnetic body.

A plurality of coil patterns 420 connected to each other through a plurality of via holes 410 alternately from the upper side to the lower side and from the lower side to the upper side are formed.

The coil pattern of the upper coil pattern forming layer 100 is connected to the via hole formed in the through hole layer 200 and the via hole formed in the lower coil pattern forming layer 400 on the lower side, Thereby providing a coil shape.

On the other hand, Ni-Fe based pemalloy is used as the magnetic material described in the invention.

As shown in Fig. 9, the above-mentioned Fishby Brothers 1 air-core coil sensor and Fishby Brothers 2 air-

An upper coil pattern formation layer 100a formed of a non-magnetic material and having a plurality of coil patterns 120a connected to each other via a via hole 110a alternately from the upper side to the lower side and from the lower side to the upper side;

A through hole layer 200a located on the lower side of the upper coil pattern forming layer and having a plurality of via holes 210a having the same size at both sides of the via hole 110a;

And a plurality of coil patterns 420a formed on the lower side of the through hole layer and formed of a nonmagnetic material and connected to each other through a plurality of via holes 410a alternately from the upper side to the lower side and from the lower side to the upper side, (400a).

The difference from the PCB type ZCT device 1000a is that a central core layer made of a core material is not formed at the central portion.

On the other hand, the material of the user's body described in the present invention,

A flexible material, and a rigid material.

That is, since it is formed inside the circuit breaker case, it is preferable that the circuit breaker is made of the above-mentioned material so that the shape thereof can be changed according to the shape of the case.

The method using the conventional CT device is the most accurate and ideal, but the disadvantage is that it is expensive and expensive because it is expensive. In particular, it is not applicable to small circuit breakers because of its large CT structure.

However, the above problems can be solved through the present invention.

Specifically, since an air-core coil sensor is used, the saturation point is high, so that the output characteristic can be almost linear (linear).

Therefore, in the present invention, it is possible to detect an overload current (100A to 10,000A), which is an accident current, by using the excellent linearity of the air-core coil sensor, and the problem that the internal space is narrow on the mechanical structure of the circuit breaker, In other words, the cost reduction effect and the space limitation can be solved by forming the one-side shape into the shape of the PCB.

In the case of an air-core coil sensor without a core layer, it is difficult to detect a minute current, but it is operated at a large current of 2.5 to 20 times, and an overcurrent of B, C, D type can be detected.

As a result, the present invention provides a circuit breaker capable of detecting an overload current and detecting a leakage current.

On the other hand, in the case of the conventional coil type ZCT element or CT element, since the coils are wound using a winding machine, characteristics are necessarily changed due to unevenness in spacing, cross generation, and the like.

However, in the case of the present invention, the patterns are formed while maintaining a constant gap, so that the overall shape of the patterns has a shape in which the coil is wound, so that uniform characteristics can be provided during mass production.

That is, if the coils are wound by a winding machine or a manual operation, the spacing between the coils may not be uniform, and coils may be united. In particular, even in a shape other than a circular shape,

For example, when a winding machine is used, only a circular detection element can be used. However, in the case of an elliptical shape, a rectangular shape with an angled corner, or a triangular shape, the gap must be unbalanced and uniform characteristics can not be provided.

In addition, as the industrial structure develops day by day, the structure of industrial machinery is changing to various forms.

For example, in the case of a current detecting element constituted in a solar inverter, a circle is unsuitable.

However, in the case of the present invention, various shapes can be applied to any industrial machine structure, but the effect of excelling in joining with the existing industrial machine structure without increasing the manufacturing cost is exerted.

In other words, since there is no human intervention and no mechanical error, it is possible to provide a uniform quality and miniaturization in size, and to exhibit a synergistic effect that various types of detection elements can be provided.

Through the above-described configuration and operation, it is possible to provide a ZCT element and a fish-less type air-core coil sensor or a fish-core type ZCT element capable of detecting an overload in a small-sized earth leakage breaker case and a fish- The present invention provides a circuit breaker having an instantaneous detection function that can prevent a short circuit or an overload when the circuit breaker is overloaded or overloaded. There is provided a circuit breaker that provides instantaneous functions that can be detected at the same time.

In addition, a ZCT element, a fish-less type air-core coil sensor or a fishbone core type ZCT element capable of detecting an overload, and a fish-type air-core coil sensor capable of detecting an overload can be simultaneously configured in a small- Are integrated into the PCB, which is a printed circuit board, to provide an effect of enhancing the humidity-resistant characteristic and the reliability of the product performance.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive.
