Abstract

The invention provides a data transmission device for a distribution transformer metering tank. The data transmission device for the distribution transformer metering tank comprises a distribution transformer metering tank body, sensing equipment, an action execution mechanism and a background monitoring system, and is characterized by further comprising a distribution transformer data forwarder realizing data storage and data processing; and the input end of the distribution transformer data forwarder is connected with the second output end of the sensing equipment, and the output end of thedistribution transformer data forwarder is connected with the input end of a communication server through a wireless network. Compared with the prior art, the distribution transformer data forwarder is added in the distribution transformer metering tank, bulk capacity storage is introduced, the data storage, processing and forwarding functions are realized and the data storage capability is enhanced; moreover, the data transmission device is seamlessly connected with the front-end sensing equipment, a communication link and a background monitoring center so as to guarantee that electric powerdata can be reliably transmitted to the background, thereby greatly enhancing the practicability of the system.

Description

technical field [0001] The invention relates to a power distribution equipment in a power system, in particular to a data transmission device and a data transmission method for a distribution transformer metering box (referred to as a distribution transformer box). Background technique [0002] The distribution transformer metering box (referred to as the distribution transformer box) is mainly installed with the community substation, the pole-mounted substation or the box-type substation. The background monitoring center is also equipped with a background data management server, which forms a data transmission system between the distribution box and the distribution box through wireless communication, and is mainly responsible for the unified management of real-time data from the distribution box. [0003] Usually, the distribution box is mainly composed of the following parts: box body, action actuators such as compensation capacitors, measurement and control devices (used...

Problems solved by technology

[0004] In the existing technology, after the distribution box data transmission system collects data through the measurement and control device, it generally forwards it directly through the standard GPRS wireless communication module. Since the standard GPRS module only has the transparent forwarding function, the storage and processing of data in the distribution box The process is completely realized by front-end sensing devices such as reactive power compensation measuring and control instruments. However, due to the functional limitations of front-end sensing devices such as reactive power compensation measuring and controlling instruments, the system often adopts the passive working mode of background calling and terminal response call test command, the terminal responds to the background command, and then starts data collection and transmission), which greatly restricts the overall data storage and processing functions of the system, often resulting in low data forwarding capabilities and unguaranteed transmission reliability. question

Since the on-site power data of the distribution box cannot be reliably transmitted to the background server, the user cannot see the real-time power data in time. In order to obtain the power parameters, the user still needs to collect data locally in the on-site distribution box. Not only the parameters The reading cost is high, the operation is inconvenient, and the real-time data lags behind, so the function of the distribution box data input system is greatly reduced
