Problems solved by technology
[0007] Aiming at the technical problems existing in the prior art, the present invention provides a terminal temperature monitoring system of a single-phase electric meter. On the one hand, it solves the need of the temperature probe in the prior art to monitor the temperature of the connection terminals of the electric meter because the withstand voltage level cannot meet the requirements. On the other hand, by monitoring the temperature of the terminals of the single-phase ammeter and setting corresponding program rules to output alarm and trip control, the safety of the use of the one-way ammeter can be improved, and it is also beneficial for maintenance personnel to carry out inspection and maintenance

The invention provides a terminal temperature monitoring system of a single-phase ammeter. The terminal temperature monitoring system comprises a temperature probe, a temperature acquisition module, an MCU, the single-phase ammeter and a magnetic latching relay. The temperature probe comprises a live wire temperature probe and a null line temperature probe, the unidirectional ammeter is provided with a plurality of wiring terminals, and the wiring terminals comprise a live wire wiring terminal and a null line wiring terminal; the live wire temperature probe is arranged at one end of a live wire wiring terminal of the single-phase ammeter, and the null line temperature probe is arranged at one end of a null line outgoing terminal of the single-phase ammeter; the temperature probe is connected with the temperature acquisition module, and the temperature acquisition module and the magnetic latching relay are respectively connected with a signal input end and a signal output end of the MCU; by monitoring the temperature of the wiring terminal of the single-phase electric meter and setting corresponding program rules to output alarm and trip control, the use safety of the one-way electric meter can be improved, and meanwhile, the one-way electric meter is favorable for maintenance personnel to check and maintain.
Description
technical field [0001] The invention relates to the technical field of instrumentation monitoring, in particular to a terminal temperature monitoring system of a single-phase electric meter. Background technique [0002] At present, there are two main types of single-phase electric meters: [0003] State grid electricity meter, this kind of electricity meter is mainly suitable for civil metering calculations, because the relevant standards are so well formulated that the functions of all this type of meters are almost exactly the same, and the relevant standards do not specify the temperature measurement of outgoing terminals, so this type The meter does not have this function. [0004] Commercial meters, this kind of meters are mainly used for commercial metering and calculation, and are not subject to the mandatory constraints of national standards, so almost all of them focus on simple functions and low cost, and no manufacturers invest in the development of this functio...
