Problems solved by technology
The power of the power grid is transformed by the distribution transformer and sent to thousands of households. The current operating distribution transformer and the 400V power distribution system below are basically out of order because they cannot be monitored in real time. The user will notify the maintenance personnel to repair the equipment. It takes a long time to deal with faults and has a great impact on power outages for users. Therefore, the reliability of power supply is low and the damage rate of equipment is high, which cannot meet the requirements of continuous improvement of people's living standards. In the event of a transformer phase loss accident, the maintenance personnel will be able to carry out emergency repairs at the scene as soon as possible, shortening the accident handling time, increasing the power supply, and increasing corporate and social benefits

Embodiment Construction
[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0013] figure 1 It is a block diagram of a remote alarm for distribution transformer phase loss of the present invention, including a signal acquisition circuit 1, a signal judgment circuit 2, and a wireless alarm transmission circuit 3; the signal acquisition circuit is connected to the signal judgment circuit, and the signal judgment circuit is connected to the wireless alarm launch circuit.
[0014] The lack of phase alarm is installed on the load side of the high and low side fuses of the distribution transformer respectively. When the melt of a certain phase fuse is blown, the signal acquisition and judgment circuit will immediately transmit the phase loss signal to the wireless alarm transmitter circuit. Carry out a remote alarm, and transmit the signal to the mobile phone of the on-duty personnel. The on-duty personnel will go to the sce...

The invention relates to a phase-missing remote alarm for a distribution transformer, comprising a signal acquisition circuit, a signal judgment circuit and a wireless alarm transmission circuit; the signal acquisition circuit is connected with the signal judgment circuit which is connected with the wireless alarm transmission circuit; when the running distribution transformer generates phase loss of a certain phase of fuse, due to melt fusing or other reasons, an induction electrode A induces no power, and a G electrode of a junction field effect thyristor V1 is not electrified so that the resistance between an S electrode and a D electrode of the junction-type field effect thyristor V1 is very little; a circuit is switched on so that a normally open contact of a solid-state relay (SSR) is closed to immediately transmit a phase-missing signal to the wireless alarm transmission circuit for remote alarming; the phase-missing signal is transmitted to a mobilephone of an operator on duty; the operator on duty goes to the site in the first time for processing as soon as acquiring the alarming situation; and therefore the time for processing electrical equipment malfunction is shortened, the power supply reliability is improved, and enterprise and social benefits are increased.
Description
technical field [0001] The invention relates to a remote alarm device for lack of phase during operation of distribution transformers, which is used for remote alarming when high and low voltage fuses are blown during operation of power supply transformers in distribution networks. Background technique [0002] At present, with the rapid development of industrial and agricultural production, the rapid improvement of the national economy, the continuous improvement of people's living standards, the unprecedented development of the power industry, and the rapid development of the national power grid construction. The power of the power grid is transformed by the distribution transformer and sent to thousands of households. The current operating distribution transformer and the 400V power distribution system below are basically out of order because they cannot be monitored in real time. The user will notify the maintenance personnel to repair the equipment. It takes a long time...
