Description

Module for performing only a minimum function such as stopping function and calculating timer for electric load in a certain time in response to the incoming electrical quality and a module for applying the electric appliance {Module for Electricity Appliance which stops the function of making Electric loads for a time according to the Electricity quality and the Electricity appliance which uses the module}

The present invention analyzes and judges quality factors such as frequency, AC voltage, distortion, and flicker of electricity introduced into electrical equipment using various electricity, and when quality of electricity is drawn in from a predetermined level that is assumed as a standard or standard. Electricity that judges the degree of the level and cuts off the occurrence of the electric load mainly performed by the electric equipment for a certain time or a predetermined time proportional to the level and performs the time timer function to resume the electric load after a certain time. An electrical entry module of an article.

 The main purpose is that the frequency, alternating voltage, distortion of the physical value that is intentionally or naturally representing the quality of electricity intentionally or naturally to the electricity supplied to the consumer in proportion to the fall of the power reserve in the grid, or the extent to which the deviation is outside the standard or standard In response to the supply of electricity in a certain aspect in accordance with the protocol of the predetermined protocol in a constant high and low pattern, the electrical appliance automatically responds to the use of the electric load in the case of the quality of the supplied electricity corresponding to a predetermined predetermined standard. It automatically cuts off the electrical load of each electrical appliance in the grid to cut off the total demand for electricity in the grid, and prevents blackouts, or blackouts, caused by overloads in which the electricity supply does not respond to the demand. Technology to solve at the level of the article .

Ultimately, the problem to be solved with the published patent 1 is the same. However, in the case of the above Patent No. 1, there is no doubt that it is a good way to prevent blackout, which is a nationwide electricity supply interruption, but it requires economic or administrative, legal or political and economic burdens and costs to implement it on a large scale. I would like to present a technically alternative way to solve this problem.

In the case of Publication 1, it is necessary to process the control of the branch circuit at the distribution panel level, and in order to do this, it is necessary to separate and bury and separate and manage the wirings according to important grades, so as to legally enforce them and to construct them at once. There is a problem in implementing the effect of the invention is made nationwide more than a certain level by demanding the economic burden.

 Due to the regulation of the indoor wiring network embedding itself, the progress of implementation nationwide is also very slow, so it takes a long time to enjoy the effect that the present invention intends to implement. Therefore, the present invention lowers the implementation level to the level of the electrical appliance that generates an electric load that is lower than the indoor wiring level of the customer, and applies the same to the manufacture of the electrical article by applying the effect of the present invention. Easier and more convenient, less economic, administrative, legal, political and economic burden to implement.

It is a physical element that represents the quality of electricity introduced into the electrical inlet of electrical appliances that generate a lot of electrical load such as air conditioners, motors, and heating devices. Intentionally separated from the standard baseline in order to broadcast to each customer, either spontaneously or presently, the current state of the power reserve is very unstable. In-house wiring is intentionally implemented in the form of a module that responds to the quality of incoming electricity that blocks its occurrence of electric load for a certain period of time, in contrast to its own standard, in the form of a module. I do not have to manage and bury itself Do not need a huge dose of black envy indoor boat-related cost in order to prevent Out is possible to gradually implement progressively the same effect.

The basic effect of the invention is the same as that of Patent Publication 1. However, the present invention significantly reduces the economic, legal, and administrative costs of the patent publication 1, and the political burden due to forcing the burden of the consumer, the ratio of a certain consumer at a national level or more in order to effect the invention. The present invention provides a way to gradually bear the burden of having to implement 1, and it is possible to realize the effect of the ultimate invention easily and gradually pursued by Patent Publication 1 without forcing a rapid burden of internal construction on the electricity consumer. It works.

In addition to preventing blackout, a nationwide blackout, if you have safety measures to manage the entire network against these risks, you can safely maintain a relatively low level of power reserves, which should always be kept above a certain level. Even with the low power reserve ratio, it is possible to reduce the fuel cost for the huge power generation for reserve power generation.

In the case of implementing Patent Publication 1, the electric monitoring center that monitors a nationwide or broadband electricity supply network such as a power company or a power exchange pays attention to maintain a certain level as a power reserve ratio as a difference in supply and demand for power. If the power reserve falls below a certain level, the risk level is recognized accordingly, and the quality of the physical physics of electricity to the electricity supplied to the consumer at each stage of the power generation and transmission network to the terminal customer, and at the stage of power generation, transmission and distribution. The value, that is, the voltage, frequency, distortion, etc., is a certain deviation from a predetermined reference value, or the deviation is a predetermined high and low pattern, which is produced by the protocol as promised to each other. When electricity is supplied with physical values that deviate from a certain standard due to the natural deterioration of electricity quality due to mismatch of supply and demand of wide area electricity, the quality of these supplied electricity is judged at the electrical inlet of the electric equipment that uses it. When the movement that generates the electric load of the electrical equipment by itself The invention is embodied in the form of a module which functions as a switch for stopping a stop or an electric device to which the module is applied.

Look at the configuration of the internal functional unit of the terminal load automatic control module 100 in more detail. The electricity drawn through the distribution system along the power system via the customer's indoor distribution board is supplied to the electrical appliance 10 through a power outlet to the electrical appliance 10. The end load automatic control module 100 constitutes a part of the power supply unit of the electric appliance 10.

Its function is to determine how far the voltage or frequency of electricity entering the electrical appliance through the outlet comes from the electrical quality, or whether the elevation of the electrical quality has a certain pattern according to a predetermined protocol. This can be done by broadcasting in the form of physical quality of electricity that delivers signals to each consumer at critical stages where the power reserve ratio is close to 0% in power distribution systems or power generation and transmission systems such as utilities or power exchanges. There is an electrical quality determination unit 110 to determine whether the transmission.

According to the determination result of the electrical quality determination unit 110, the function of the load generation function unit 200 of the electrical appliance 10 is selectively blocked and relayed. The electrical quality detection unit 110 grasps the degree of pattern separation or the degree of separation of a predetermined standard value based on physical constants indicating voltage, frequency, and other electrical quality.

The blocking target confirmation unit 120 performs a function of checking whether the actual load of the electrical appliance controlled by the actual module is controlled based on the information identified by the electrical quality detection unit 110. In case that the blocking target checking unit 120 confirms that the blocking target is a blocking target, a relay, a fuse, or a photo that can be electrically interrupted in addition to a switch-type blocking device in order to cut off the function of the load generating function unit 200 of the electrical appliance. Transistor There is a switch signal generation unit 130 for generating a signal that can be controlled by other electrical, mechanical, optical, and other physical signals. As a result of the determination of the electrical quality detection unit 110 and the blocking target confirmation unit 120, the switch signal generation unit 130 determines whether to permit the use of the load of the electric device.

The blocking target confirmation unit 120 determines in advance how to cut off the load in response to the electric quality by determining the various grades according to the types of power-hungry air-conditioning equipment, motors, and other power-consuming devices, and the size of the power consumption. By determining the type and grade of the end load automatic control module 100 and storing the grade of the stage that differently determined the range of the object confirmation that the blocking object identification unit 120 has according to the priority of the electrical appliance to which the module is mounted. The module blocks the function of the load generation function unit 200 by contrast with the electrical quality grasped by the electrical quality detection unit 110. The blocking method is to generate a signal for interrupting or resuming the function of the load generating function unit 200 coupled to the module by using electrical, mechanical, optical, or other physical means through the switch signal generation unit 130.

The terminal load automatic control module 100 may cut off and connect the function of the load generating function unit 100 according to a predetermined condition, and when a predetermined time has elapsed even when a broadcasting signal of a rating that is blocked or may be reconnected is confirmed. Only then can the timer 140 for time management be made to reload. Since the use of the timer 140 is not desirable to deliver to the consumer for a long time of the electric quality separated from the normal standard value, even if the electricity supplied to meet the normal quality standard within a certain time again, the priority is already low, so that the interrupted end load is immediately reloaded. This is to avoid.

 Each component constituting the terminal load automatic control module 100 may be implemented in part or in whole in a single electrical element or module, or may be implemented by circuitry connected to separate objects.
