BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sequential power injection apparatus using a dial-time relay,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sequential power-on apparatus using a low-power contract power saving dial time relay, and more particularly, to a power- The power consumption of a plurality of electrical appliances connected to a plurality of electrical outlets is maximized by delaying the power supply by a set time for each of the multi-outlets by using the contact switch to prevent simultaneous start of the load and the timer driven time- And more particularly, to a power-saving dial-time relay utilizing sequential power-on device.

The prior art related thereto discloses a 'peak power reduction device' according to utility model application No. 20-1999-0012885. Conventionally, a sparking battery or a capacitor bank is used for supply of a large power required in the operation of the high load equipment, and it is difficult to apply the battery to a system in which an AC power source is used, and a capacitor bank is required to have a high precision The peak power reduction device of the present invention adopts the peak power reduction device composed of the rotation converter and the control means to store the energy at the lower load and to convert the stored energy into the momentarily large power when the peak load is applied So that a large peak power can be stably supplied.

In addition, according to Patent Publication No. 10-2011-0138812, a 'network system and an energy consumption unit' are disclosed. An energy consuming unit according to one aspect includes communication means for receiving energy information; A display unit capable of displaying energy information and operating state information; And an input unit for inputting an operation mode. When the operation mode is selected by the input unit, energy information related to the mode selected on the display unit can be displayed.

The network system is a power plant, a power plant, a substation, an energy management system (EMS), an appliance, an appliance, a smart meter, a capacitor, a measuring device (AMI, Advanced Metering infrastructure, and home server are components of the network system.

Electricity generated in a power plant is transmitted to a power station through a transmission line, and electricity is transmitted to a substation in a substation. In a substation, electricity is supplied to a household, a building, a factory, .

The power supply company determines the supply condition according to the electricity supply regulation when supplying electricity to the customer, and the contract power is applied to the customer having the electric water supply facility, and at the same time, .

Houses, buildings, and factories receive electricity through pillar transformers and distribution boards.

The distribution board is an electrical equipment that receives electricity and distributes electricity to each load. The distribution board is equipped with a main circuit breaker connected to two lines of commercial power, ground wire (ground) and supply terminal, and a breaker (electronic contact breaker) with several small capacity in the left and right direction is installed beneath it. It can be divided into electric lamp and electric heating load, so that if a circuit breaks down or malfunctions, only the circuit is cut off and other electric equipment is used safely.

For example, when the contracted power in the home is 3 kW or 5 kW, 3 kW and 5 kW of electricity are supplied from the pillar transformer to the domestic panel 1 and the panel panel installed in the house 2, respectively.

Generally, when an electrical product is connected to a multi-outlet connected to a distribution board, the average power is supplied to the electrical product when a predetermined time elapses after the initial maximum power peak value (instantaneous value).

However, if all the electrical appliances of the electrical household are simultaneously connected and powered on to all the electrical outlets connected to the distribution board, the total value of the maximum electrical power peaks (instantaneous values) suddenly increases suddenly, There is a problem that a safety accident such as a power failure occurs because the power consumption of the power supply system exceeds the contract power set as the power supply amount of the supply system.

Therefore, the power system must be stably managed so that the electric power consumption of all electric appliances of the electric consumer is always lower than the electric power supply amount of the supply system. The maximum power peak value (instantaneous value) of all appliances of an electrician connected to the multi-outlet formed at the individual load at any moment, such as power failure, should not be summed simultaneously.

It is an object of the present invention to solve the problems of the prior art, and it is an object of the present invention to provide a sequential power-on device using a low-power-consumption contract power saving dial time relay.

When setting the contract power, the power supply side should maximize the safety value of the breaker while the consumer side should set the minimum contract power value. In this case, the set contract power value is a factor that increases the amount of reserve power reserve on one side, while it is linked to the factor that raises the contract power maintenance cost on one side, so it is important to select the value when calculating the economic breakeven point for both sides . Therefore, development of the present invention is useful and necessary in order to select an appropriate contract power value.

In order to accomplish the object of the present invention, a low power contract power saving dial time relay using sequential power input device is provided with a commercial power supply for distributing electricity for each load at a power load stage of the power supply system; A circuit breaker connected to the commercial power source, the ground line, and the power supply terminal line to protect an increase in current flow from overload and short circuit; A plurality of multi-outlets to which the wiring breaker, the ground wire, and the power supply terminal wire are respectively connected and to which various kinds of electrical products are connected; A plurality of electronic contact breakers (breakers) having one side connected to the wiring breaker and the two wires respectively and the other side connected to each of the time division power controllers (Delay Timer) and the two wires; And a plurality of electrical outlets connected to the plurality of electronic contact switches (40-1, ..., 40-n), respectively,

And the other side of the circuit breaker is connected to the grounding line and the power supply terminal line, and the other side is connected to the two contactors by the timer. and a plurality of time division power controllers (Delay Timers) that are restored to the return contacts upon shutdown after a time delay operation.

The present invention requires a sufficient margin to prevent situations where the power consumption exceeds the contracted power even momentarily due to a design or management error between the power supply and the power supply system or one side. It is possible to manage the power peak value and effectively cope with the contract power maintenance cost and the national blackout phenomenon.

By attaching the present invention to the target site of the present invention by supplying electric power to the commercial power source and the self power generation facility, or by those who consume power or design the electric power, the contract power set value can be minimized to reduce the power management expenditure cost, As a device capable of effectively preventing a blackout phenomenon in which a power transmission power of a power plant is insufficient.

If blackout is overpowered in buildings, factories, and households, if the electricity usage exceeds the supply of the power plant, the voltage and frequency of the entire power grid will drop significantly. As a result, the system that controls the strategic network will stop altogether, This is a phenomenon in which electricity is totally lost due to power failure.

In the supply system, the power system must be stably managed so that the power consumption is always lower than the power supply amount of the supply system. A sequential starter with a combination of an electronic contact breaker and a time-sharing power control device (Delay Timer) was built so that the power peak value (instantaneous value) formed at the individual load at any moment such as power failure can not be added simultaneously.
