Novel acquiring terminal of specific power transformer

Abstract

The invention discloses a novel acquiring terminal of a specific power transformer. The novel acquiring terminal comprises a microprocessor; the microprocessor is connected with a power conversion unit, a metering unit, a storing unit, a display unit, an internal relay control unit, a pulse input unit, an RS485 meter reading unit, a state value input unit, a GPRS communication unit, a local communication unit, an internal relay connection state detection and indicating unit, a state value connection terminal strong anti-interference unit and a GPRS communication unit automatic heating unit. According to the novel acquiring terminal of the specific power transformer, the internal relay connection state detecting and indicating unit is used for detecting the connection state of a control loop, the state value connection terminal strong anti-interference unit is used for resisting static interference, the GRPS communication unit automatic heating unit is used for automatically heating a GPRS communication unit at low temperature, and therefore, the product reliability can be improved, the mis-operation due to inaccurate connection can be removed, and the safety coefficients of power workers and devices can be increased.

Description

technical field [0001] The invention relates to the field of equipment for collecting user electricity information in an electric energy intelligent collection system, in particular to a new type of special variable collection terminal.

Problems solved by technology

Although the energy of electrostatic discharge has little effect on traditional discrete devices, the electrostatic field and electrostatic current generated by static electricity have become their fatal killers, making their functions invalid or causing soft breakdown that is hard to find, thus leaving a lasting impression on electronic products. Hidden dangers may cause product hardware damage or malfunction, directly affecting product quality, life, reliability and economy

Existing special variable acquisition terminal products also use a large number of integrated devices, so the protection of static electricity is also particularly important. The damage caused by static electricity to the product will affect the instability of the collected data or damage the equipment itself, and affect related operations. normal operation of

At present, the state quantity access terminal of the special variable acquisition terminal on the market is damaged due to static electricity, which will result in inaccurate or impossible judgment of the opening and closing state of the external circuit breaker

[0005] In addition, in the actual use of the special variable collection terminal, with the difference in the region, the ambient temperature directly affects the normal operation of the GPRS communication unit of the variable collection terminal. When the external temperature reaches -10℃~-20℃, the The GPRS communication unit of the special change acquisition terminal will not go online or go online slowly. Most of the reasons for this situation are that the SIM card holder in the GPRS communication unit is deformed at low temperature, resulting in poor contact of the SIM card, or the SIM card is exposed to temperature. Cannot work when too low and cause
