Description

[0001] The present invention relates to an integrated type Citi device for instantaneous current detection applied to a circuit breaker,

[0001] The present invention relates to a device for integrated current detection for instantaneous current, which is applied to a circuit breaker, and more particularly, Integrated type semiconductor device capable of instantaneous current detection by forming 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.

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 thickness of the ZCT element is -10 mm and the thickness of the CT element is -10 mm x 2, a space for mounting a total thickness of about 30 mm is required.

That is, as shown in FIG. 1, the distance from the PCB 30, which is a conventional ZCT device, to the terminal 30 to which the electric wire 20 is coupled is 10 mm, Is impossible.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a semiconductor integrated device capable of detecting instantaneous current by utilizing the periphery of a through hole in a main PCB, in which a conventional ZCT device is formed, .

Current circuit breakers comprise 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, in the present invention, by providing a ZCT element and a fish-free type hollow core coil sensor capable of detecting an overload, it is possible to provide an installation structure in a narrow space.

Preferably, the size of the main PCB including the sensor unit of the present invention is not more than 3 cm in width, 2.3 cm or less in length, and 0.1 cm or less in thickness.

In this case, internal lamination of the sensor assembly 1000b and the sensor assembly 2000b is formed in the same manner as in the embodiment or example. In order to detect a large current, the upper coil pattern forming layer 100, An insulator 200, and a lower coil pattern forming layer 300,

The upper coil pattern forming layer 100, the insulator 200, the lower coil pattern forming layer 300, and the magnetic core member 400 are formed for low current detection.

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.

That is, since there is no human intervention, and there is 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 CT detection elements can be provided.

In order to secure a space for forming a CT element on a circuit breaker structure having a narrow space, it is possible to provide a semiconductor integrated type device capable of instantaneous current detection using the periphery of the through hole in the main PCB, The present invention provides a circuit breaker having an instantaneous detection function that can prevent a short circuit or an overload when a short circuit or an overload is generated. And provides instantaneous functions that can be detected.

In addition, as a result of the integration of various analog parts in the PCB, which is a printed circuit board, by constituting the Fishby Brother 1 air core coil sensor (1000) and the Fishby Brother 2 air core coil sensor (2000) in the narrow earth leakage breaker case, Thereby improving the reliability of the performance of the system.

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.
