New description: [New technical field] This creation is related to a power-saving device, especially a power-saving control device that limits the simultaneous operation of multiple loads. [Prior Art] Since the formation of the Earth, the composition of the atmosphere has remained unchanged from time to time, especially in the case of micro-gas, but the influence on the global environment has a decisive factor. The principle of global warming is the greenhouse. The atmosphere absorbs the long-wave radiation released from the surface of the earth and then reflects it back to the ground. Through this natural greenhouse effect, the temperature of the surface is maintained. Alas, in recent years, due to the rapid growth of the human economy, the manufactured products and the resulting air pollution, the speed of the former M-Machine has not been changed, and the yarn has been changed. In particular, after the fossil fuels are burned, the (3) 2 gas produced by 70 Jun, after being discharged into the atmosphere in a large amount, absorbs the long-wave light from the surface, causing the artificially increasing surface temperature. ' j Due to the greenhouse effect, when the heat wave Invasion, in order to avoid "% people often receive a common place (❹大v A reduction in the public or the public, ~ cold Gong to avoid the outdoor heat waves. Of course, there are helmets at home or public places due to, ', resulting Helmets, 牟 + + Μ Μ 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 - Adjust the indoor temperature.

The load that can be withstood, As a result, the substation jumped or damaged, causing many households to have no electricity available. [New content],, therefore, this creation proposes that the type of limited-capital load can be started or operated at the same time: power saving I can limit multiple negative cuts simultaneously Start the operation to avoid the overload of the belt, which will increase the electricity bill, and thus save the power and electricity: In order to achieve the above objectives, the multi-load power-saving device of the present invention includes: the first control module, including·· Seven N ratios arranged in contact 11 and no hysteresis power-off H electrical connection to induce current flow between the contactor and the insoluble filament breaker; N and contactors, external lightning setting丨 丨 power supply and current-current connection of the current connection = contactor, external power supply and n current setter electrically connected coil = two: the coil end of the device and N circuit switch contacts and contacts The core power supply and the two normally closed I of the N circuit switches occupy the contact and the sound are connected to form a dual power supply and connect the circuit.

The third cold air 43 is connected to the coil end 432 of the M318741 contact state 431 in a single power supply series circuit. The two normally closed contacts 6 are in a single power supply series circuit with the first normally closed 'point 633 of the sixth circuit switch 63, the external power source 5〇, and the coil end 412 of the contactor 411 of the first cool air 41. The contacts 411, 421, and 431 of the cold air 41, 42, 43 are electrically connected to the power switches 44, 45, and 46, and a current divider (442, 452, 仙2) is disposed on the wires 441, 451, and 461. The current transformers 442, 452, and 462 are electrically connected to the respective current setting devices n, 12, 13, 51 52, and 53. In the present drawing, the electricity is The switches, 45, and 46 are no-fuse circuit breakers. When the first, second, and third switching switches 31 of the switching module 30 are switched to the normally closed contacts 312, 322, and 332, the first control mode is used. The group 1 is controlled by the current. When the contactor 411 of the first cold air 41 is turned on, the power switch 44 transmits the power to the contactor 4, and the current comparator 442 outputs when the current sense_current flows. A signal drives the coil end 111 of the first current setting 11 to switch from the normally closed contact 113 to the normally open contact 114, so that the coil end 211 of the first loop switch 21 is activated, so that the first system is closed. 212 and 213 are in an open state, and one of the second and third cold airs 42 and 43 is cut off, and the external power supply 5〇 flows through the second normally closed contact 223 and the third return switch of the second return switch 22. The first normally closed contact 231 of 23 causes the compressor 47 of the first cool air 41 to start running. When the contactor 421 of the second cool air 42 is turned on, the power switch 45 transmits the power source to the contactor 411 at the specific flow. When the device 452 senses a current flow, the current comparator 452 outputs a signal to drive the second current setting. Line 1 of the 12, M318741, the end 121 of the ring, the normally open contact 123 is closed, and the coil end 221 of the second circuit switch 4 is activated, so that the first and second normally closed contacts 222 are in a closed state, and the first is cut off. One or three of the cooling air gases 42 and 43 are powered back and the power source will flow through the second normally closed contact 232 of the third circuit switch 23 to cause the compressor 48 of the first cold air 42 to start running. In the foregoing first and second cold air 41 When the operation is started at 42, the first and second normally closed contacts 212 and 213 of the first circuit switch 21 and the first and second normally closed contacts 222 and 223 of the second circuit open (four) # are opened and closed. The parallel connection circuit of the third cooling air supply has been cut off, so the third cold air illusion cannot be started. When the first and second cold air 41, 42 have a stop operation, the first and second normally closed contacts 212, 213 or the second return of the first circuit switch 21, the first and second normally closed contacts 222 of the switch 22. One of the first normally closed contacts 213 of the first circuit switch 21 of the third cold air 43 or the first normally closed contact of the second circuit switch 22 is changed to the closed state. And pick up the back, so the third cold air can be pushed back. When the first, second, and third switch 31s of the switching module 30 are switched to the normally open contacts 313, 323, and 333, the second control module 2 is electrically/melted. When the contactor of the first air conditioner 41 is turned on, the power switch 44 transmits the power source to the contactor 4, and the current comparator 442 outputs a signal to drive the fourth when the current is flowing through the comparator. The coil end 511 of the current setter 51 is operated, and is switched from the normally closed contact (10) to the normally open contact 514, so that the coil end 611 of the fourth loop open_ is activated, and the first closed loops 612, 613 are opened and closed. , and cut off the second and third 13 M318741 cold air 42, 43 power series circuit, open _ the second normally closed 336 heart ^^5 () stomach through the fifth circuit contact coffee 1] two & six The compressor of the first-closed person of the circuit breaker 63 is turned on. Power supply series circuit: η two-knife break the second and third cold air 42, 43 gas thanks to the operation: (four) four operation. ΐ第-冷二, closed state, at this time the second, third, like it - can be: start running, but in the second and third cold air 42, 43 one of the first will be one, three cold f 4], # Seven Seven, ", one air-conditioning 41, 42 can not be activated, - effective to limit the power-saving devices that run multiple loads at the same time.
