High-speed communication system of intelligent transformer substation

Abstract

The invention discloses a high-speed communication system of an intelligent transformer substation. The high-speed communication system comprises a communication host box which is made of an insulating waterproof material; the outer shell is a flat type cuboid; a fixed frame is welded to the backside of the communication host box; the fixed frame is fixed at a transformer outer box by tightly screwing fixing screws; a solar cell power supply module is installed at the upper surface of the communication host box; a communication circuit board is fixedly arranged at the interior of the communication host box through support screws; a communication unit integrated circuit is welded to the communication circuit board; a rotary camera is fixedly installed at the lower surface of the communication host box; the solar cell power supply module is used for converting solar energy into electric energy and supplying electricity to the communication circuit board and the rotary camera; an interface panel is also embedded at the rear panel of the communication host box; metal interface terminals are embedded at the interface panel; and the metal interface terminal is of a metal terminal structure; a metal core is connected with a positive electrode; and a metal shell is connected with a negative electrode.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a high-speed communication system of an intelligent substation. Background technique [0002] Substation, a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. According to the size, the small ones are called substations. A substation is larger than a substation. Substations generally refer to step-down substations with voltage levels below 110kV; substations include "boost and step-down" substations of various voltage levels. A substation is a power facility in the power system that transforms voltage, receives and distributes electric energy, ...

Problems solved by technology

As an effective test method, automatic testing has long been a research hotspot in the industry. However, due to the inconsistent external interfaces of traditional substation relay protection devices (such as too many communication protocol versions, inconsistent list of fixed values, and inconsistent content formats of action reports, etc.), It largely limits the practical application of automated testing

At present, the testing work of most relay protection devices, especially the static model test, still adopts the traditional method of manual testing using a relay protection tester, which has the disadvantages of low test efficiency and large influence of human factors.
