Abstract
The utility model relates to a power saving device, applied to a three phase motor, comprising a high voltage isolation switch, a contactor and an auto transformer. One end of the high voltage isolation switch is in connection with an external power line to receive external 400 V voltage, and the other end of the high voltage isolation switch is in connection with one end of the contactor; the other end of the contactor is in connection with one end of the auto transformer, and the other end of the auto transformer outputs 380 V voltage through an outgoing line to be in connection with the three phase motor. According to the utility model, before the three phase motor is connected to the power supply of the external power line, the power saving device employs the auto transformer to reduce voltage; the voltage is reduced from 400 V to 380 V under the condition of meeting nominal voltage requirements of the three phase motor to save power. In addition, in order to protect the auto transformer, two tandem switches including the high voltage isolation switch and the contactor are designed; the high voltage isolation switch performs high voltage isolation protection, the auto transformer starts only when the contactor is also closed, and the contact must locate between the high voltage isolation switch and the auto transformer.
Description
Technical field
The utility model relates to a kind of battery saving arrangement.
Background technology
The society being on the rise at energy crisis and greenhouse effect, energy-conserving and environment-protective have become an eternal theme of social sustainable development.China is the country of an electricity shortage, and economize on electricity is a current important technology policy, and to be again a kind of energy development have far-reaching influence for the development of national economy in economize on electricity.According to the actual conditions of illumination and load, adjust illumination and power output, reducing unnecessary electricity consumption waste is a power-saving measures being significant.At present, China's electric product power consumption is about 70% of national total power consumption, and metallurgical system year power consumption account for 9.3% left and right of national generating capacity, so saves energy, to promoting the development of steel industry to have great significance.
Utility model content
In view of this, the utility model proposes a kind of battery saving arrangement, it is intended to promote economize on electricity new technology according to the actual conditions of above-mentioned every profession and trade, improve utilization rate of electrical, by power saving operation, make various product power consumption indexs progressively reach internal and international advanced level, to improve Business Economic Benefit.
The utility model is to realize like this, battery saving arrangement, it is applied in three phase electric machine, this battery saving arrangement comprises high voltage isolator, contactor, autotransformer, one end of this high voltage isolator connects external power cord and receives outside 400V voltage, the other end of this high voltage isolator connects one end of this contactor, and the other end of this contactor connects one end of this autotransformer, and the other end of this autotransformer is exported 380V voltage by outlet and connected this three phase electric machine.
Battery saving arrangement of the present utility model; before accessing the power supply of external power cord at three phase electric machine; application autotransformer carries out step-down; under requiring, the rated voltage that meets three phase electric machine drops to 380V from 400V; realize economize on electricity; in addition; in order to protect autotransformer; having designed two tandem taps is high voltage isolator, contactor; by high voltage isolator, carry out high-voltage isolation protective; and only when contactor is also closed, autotransformer just starts, and contactor must be between high voltage isolator and autotransformer.
Accompanying drawing explanation
The circuit diagram of the battery saving arrangement that Fig. 1 provides for the utility model better embodiment.
Main symbol description: high voltage isolator 1, contactor 2, autotransformer 3, power line 4, outlet 5, three phase electric machine 6.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, the circuit diagram of the battery saving arrangement that it provides for the utility model better embodiment.Battery saving arrangement comprises high voltage isolator 1, contactor 2, autotransformer 3.One end of this high voltage isolator 1 connects external power cord 4 and receives outside 400V voltage, the other end of this high voltage isolator 1 connects one end of this contactor 2, the other end of this contactor 2 connects one end of this autotransformer 3, and the other end of this autotransformer 3 connects three phase electric machine 6 by outlet 5 output 380V voltages.
Battery saving arrangement of the present utility model; before accessing the power supply of external power cord 4 at three phase electric machine 6; application autotransformer 3 carries out step-down; under requiring, the rated voltage that meets three phase electric machine 6 drops to 380V from 400V; realize economize on electricity; in addition; in order to protect autotransformer 3; having designed two tandem taps is high voltage isolator 1, contactor 2; by high voltage isolator 1, carry out high-voltage isolation protective; and only when contactor 2 is also closed, autotransformer 3 just starts, and contactor 2 must be between high voltage isolator 1 and autotransformer 3.
In sum, the utility model is promoted economize on electricity new technology, improves utilization rate of electrical, by power saving operation, makes various product power consumption indexs progressively reach internal and international advanced level, to improve Business Economic Benefit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
