Abstract

The utility model discloses an electric quantity loss alarm and make up device; after a current acquisition circuit and a voltage acquisition circuit acquire a fault signal in a circuit, the fault signal is processed by a high-accuracy time base generating circuit to be an electrical signal needed by a high-speed and low-power-consumption microprocessor, and then is transmitted into the high-speed and low-power-consumption microprocessor; the analyzed and judged result is transmitted into a data storage circuit by the high-speed and low-power-consumption microprocessor for storing the data; an alarm output circuit and an LCD display driving circuit are respectively and electrically connected with the high-speed and low-power-consumption microprocessor; the alarm output circuit is electrically connected with an alarm device; and a three-phase power supply circuit is used for providing the electrical energy needed by the high-speed and low-power-consumption microprocessor. The electric quantity loss alarm and make up device has the advantages of providing scientific and accurate basis for making up electric quantity due to the fault of an electrical energy metering device, maintaining the benefit balance between an enterprise and a client, and reducing dispute and professional ethos events caused by the fault of the electrical energy metering device.

Description

Electric weight is lost warning and is remedied device

Technical field

The utility model relates to the technical field of energy monitor apparatus, more particularly relates to use simultaneously and electric weight is monitored and remedied with electric power meter the technical field of apparatus.

Background technology

Along with rapid economy development, the metering precision of the newly-built transformer station in each department increases, but the reliability of measuring apparatus is not also further improved, secondary voltage circuit, current return to electrical network monitor, the running status of electrical network, the cumulative time of decompression, cutout and beginning and ending time and correlation parameter do not have detailed pen recorder between the measuring apparatus age at failure, thereby remedying of electric weight caused difficulty after giving fault, greatly damaged the economic interests of electric power enterprise.

The utility model content

The purpose of this utility model provides a kind of capable of automatic alarm when secondary circuit breaks down in order to solve above-mentioned deficiency exactly, and can lose warning and remedy device the electric weight that the electric weight of losing is remedied.

The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:

Electric weight is lost warning and is remedied device, it is mainly by high-speed low-power consumption microprocessor, the current acquisition circuit, voltage collection circuit, circuit takes place in base during high precision, the LCD display driver circuit, the warning output circuit, three-phase supply feed circuit and data are preserved circuit and are formed, after in the loop, collecting fault-signal by current acquisition circuit and voltage collection circuit, processing of circuit takes place and becomes the required electric signal of high-speed low-power consumption microprocessor to be transferred to high-speed low-power consumption microprocessor this fault-signal in time base by high precision, the signal that receives is analyzed and judged by high-speed low-power consumption microprocessor, by high-speed low-power consumption microprocessor the result transmission of analysis and judgement is preserved circuit to data again and carry out the data preservation, warning output circuit and LCD display driver circuit are electrically connected with high-speed low-power consumption microprocessor respectively, be used to show its analysis and judgement result and control warning output circuit, the warning output circuit is electrically connected with alarm, and the three-phase supply feed circuit provide required electric energy for high-speed low-power consumption microprocessor.

Described high-speed low-power consumption microprocessor also is electrically connected with gprs system.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: itself and electric power meter are used simultaneously, be attempted by in the secondary circuit, when secondary circuit breaks down, this device can be reported to the police automatically by alarm, fault data is stored in the internal memory, and in order to calling, this remedies electric weight for the electric power meter fault science foundation accurately is provided, safeguard enterprise and client's Equilibrium of Interests, reduced the dispute and the sector-style incident of electric power meter fault.
