Description

Multifunction Power Filtering Protector {POWER FILTERING PROTECTOR}

The present invention is a power filtering protector to prevent the overvoltage, overcurrent, surge, lightning, noise, etc. that may occur in the stage before the single-phase 220V AC power is introduced into various equipment (hereinafter referred to as "secondary side"). It is about.

In general, when overvoltage, overcurrent, surge, lightning, noise, wave distortion, etc. occur in single-phase 220V AC power supply to various computer equipment, power supply fault, disk crash, module fault, processing Since there is a problem such as an error or a change in the RAM setting value, the secondary power should be supplied stably.

Many conventional power stabilization circuits for solving this problem are known. However, these conventional power supply stabilization circuits have a built-in surge protection circuit only on the incoming power supply side (hereinafter referred to as "primary side") which is the stabilization circuit side, and the same one since the secondary output stage does not include a surge protection circuit. When surge, overcurrent, spark, etc. occur in one of the equipments at the output terminal of the equipment, there is a problem that harmful electricity is introduced into the adjacent equipment as it is, causing fatal damage.

In addition, the conventional power stabilization equipment itself does not have a voltmeter, ammeter, surge counter, diognostic check function, there is a hassle to purchase these equipment separately, and the system administrator must check using each of these management equipment There is a lot of inconvenience in management because it causes a lot of inconvenience in management work.

The present invention has been made to solve the problems of the prior art, a power filtering protector to prevent the overvoltage, overcurrent, surge, noise generated in each of the plurality of devices connected to the secondary side of the power stabilization equipment to reach the adjacent equipment. It aims to provide.

Furthermore, the present invention not only enables power filtering protection function having a stabilizing function but also a dignostic circuit 30 and an indicator 8 so that the AC phase can be visually checked, and the front panel 1 By configuring the voltage and current indicators 5 and 6 integrally, the power filtering protector function as well as the voltage and current of all devices connected to the protector can be checked, and the digital surge counting circuit 20 and the counter ( The purpose of the present invention is to provide a multi-function power filtering protector which can check how many jerseys and harmful electricity are introduced.

3 is a filtering circuit 10 according to the present invention, to filter the noise, surge, etc. of the incoming power source 11 to be output to the outlet (9a, 9b, 9c) of the secondary output terminal.

The filtering circuit 10 according to the present invention is composed of a plurality of varistors (V1 ... V9), coils (L1, L2) and condensers (C1, C2, C3). The emphasis is on the safety of the device by allowing it to attenuate large frequencies while passing it.

Varistor applied to the present invention is applied to the ZnO varistor as an embodiment, the maximum applied voltage is operated at AC 300V, DC 390V.

In the present invention, the secondary output stage circuit units 9aa, 9bb, and 9cc are separated to form a coil, a capacitor, and a varistor, so as not to affect each other.

The coil L1 of the circuit portion 9aa outputted to the secondary output terminal outlet 9a is connected to another secondary output terminal circuit portion in which harmful components such as overvoltage, overcurrent, surge, and noise generated by the equipment connected to the outlet 9a are adjacent to each other. 9bb) to prevent it from being delivered.

In addition, the varistors V1, V2,... V6 of the inlet end circuit unit 11 serve to block sparks, surges, overvoltages, noise, etc. generated at the secondary output end from being reversed to the primary side. The varistors are duplicated between the NEUTRAL LINE and the HOT LINE, and maximized the surge protection effect by configuring the varistors in both the NEUTRAL LINE and the HOT LINE based on the GROUND standard.

In the present invention, the counting circuit 20 and the dignostic circuit 30 for counting the inflow of the abnormal voltage can be easily understood from the circuit diagrams shown in FIGS. 4 and 5 by those skilled in the art. As such, detailed description thereof will be omitted. As such, the present invention makes power management more efficient by integrating various measuring instruments integrally with the power filtering equipment necessary for managing power supplied to various equipments, and hassle to purchase various specific apparatuses separately. Of course, a lot of costs can be saved.

Although the detailed description of the subject innovation has been described by taking specific embodiments of the subject innovation as an example, the present invention may be modified or modified in various forms in the technical field to which the subject innovation belongs without departing from the concept of the subject innovation. It is of course included in the concept.

As described above, the present invention prevents abnormal power such as noise, surge, spark, etc. generated between multiple devices connected to one secondary output terminal from affecting the peripheral equipment, thereby causing the fatality of the equipment due to the abnormal power input. Damage can be more reliably and effectively prevented. Furthermore, the present invention integrates a current indicator, a voltage indicator, an abnormal voltage counter, and a dynostic indicator into the power filtering protector so that information related to the input power of various equipments can be monitored at a time, thereby enabling actual power management. It is a useful design that works.
