Background technique

With the advent of the era of science and technology, the variety of electrical equipment and equipment is inseparable from the lifestyles of people all over the world. Therefore, the world is caught in a crisis of insufficient power. In order to supply electricity throughout the country, various countries have tried their best. If the power plant is capped, no matter what kind of power plant, in addition to the large construction cost, it will also damage the environment. In addition, it must increase the power generation capacity of the power company. When the power generation capacity increases, it is transmitted to The high-voltage transmission lines of each user must be replaced together. It is indeed a small sum of money. Therefore, the final solution in the crisis of insufficient power is still “saving electricity”.

Faced with the severe test of summer power spikes, governments in order to avoid large power outages caused by users' demand for electricity exceeding power generation capacity, in addition to requiring large power plants such as large factories and office buildings, as well as small users such as shops, schools, and homes, must conduct their own In addition to saving electricity, if the power saving effect is not good, the power company can only take power-limiting measures in the case of insufficient power. At present, the power-limiting measures are to take power restrictions in the district, that is, all the same area is cut off at the same time. Electricity will be restored after a certain period of time. Under the implementation of power-limiting measures, users will be greatly inconvenienced by power outages, which will affect daily life and work.

First, the

electric controllers

1, 1a, 1b are arranged in each of the users U1, U2, U3. For example, the power-saving controller 1 includes a first loop L1 and a first loop switch K1. The first loop switch K1 is connected to the first loop L1 and the power source PS (step 101), during a power-off period. In the control unit 11, a plurality of polling power supply sections T are recorded in advance (step 102), and a predetermined power-off time t1 and a predetermined power-on time t2 are preset in each of the polling power supply sections T (step 103).

When the method of the present invention is executed, the predetermined power-off time t1 and the predetermined power-on time t2 preset by the power-off period control unit 11 of each power-saving

controller

1, 1a, 1b are based on a mutually exclusive power-off time. The tx mechanism is set to be set, and in the rotating power supply interval T, the predetermined power-off time t1 and the predetermined power-on time t2 of the power-saving

controllers

1, 1a, 1b of any one of the users are saved with other users. The predetermined power-off time t1 and the predetermined power-on time t2 set by the

controllers

1, 1a, 1b are set to be shifted from each other (step 104).

When the user turns on the temporary power-off load E1 (for example, when the user turns on the air conditioner by the remote controller and the heater starts to operate the appliance), the power source PS supplies the current I to the temporarily power-off load via the first loop L1. E1 (step 105).

During the period when the power source PS supplies the current I to the temporarily de-energized load E1 via the first loop L1, the power-saving

controller

1, 1a, 1b controls the first loop switch according to the predetermined power-off time t1 preset in the rotating power supply section T. K1 opens the circuit and temporarily cuts off the current PS supplied to the temporarily de-energized load E1, and then controls the first circuit switch K1 to close at the predetermined re-powering time t2 to return the power supply PS to the supply current I to the temporarily de-energized load E1 (step 106). .

Each time the current supplied to the temporarily de-energizable load is temporarily cut off according to the predetermined power-off time and then the supply current is returned to the temporarily de-energized load at the predetermined re-power-down time, a counting signal may be generated by the counting unit 15 (step 107). And the processing unit 12 can calculate according to the counting signal S2 and the rated power consumption value of the temporarily power-off load E1.

For example, when planning the power saving measure, as shown in FIG. 5, a city can be divided into a plurality of partition groups A1, A2, and A3, and each of the partition groups A1, A2, and A3 includes a plurality of users U1. U2, U3, and each of the users U1, U2, U3 are respectively equipped with an

electric controller

1, 1a, 1b. For example, the power-saving measures are led by the government, and the government can mutually exclude the power-off time setting mechanism tx to plan different scheduled power-off times t1 and predetermined complexes of the power-saving controllers of each of the sub-groups A1, A2, and A3. The electric time t2, by setting the predetermined power-off time t1 and the predetermined power-off time t2, can cross-disconnect the time zones of each of the sub-groups A1, A2, and A3 for power-off and power supply, and under the control of each power-saving controller. When the power is off, only the electrical equipment that can temporarily power off the load in each user U1, U2, U3 is powered off, and the rest of the general load electrical equipment can still be used for power supply.

When the power-saving

controllers

1, 1a, 1b of the first partition group A1 power off the temporarily power-off load of each user U1, U2, U3, the second and third partition groups A2 and A3 are normally powered. . When the power-saving

controllers

1, 1a, 1b of the first partition group A1 control the return power supply, the temporarily power-off load of each user U1, U2, U3 in the second partition group A2 is powered off, The three partition groups A3 are normally powered. When the power saving controllers of the second partition group A2 control the power supply, the temporarily power-off load of each user in the third partition group A3 is powered off, and the first partition group A3 is normally powered. In this way, the interleaving and power-off of each sub-group is interrupted. In the summer, the peak period of electricity consumption can avoid the user's electricity demand exceeding the power generation capacity, and the users can achieve the power-saving effect.
