Embodiment Construction

[0019] refer to figure 1 and 2 The embodiment of the power user boundary load switch 100 is connected between the user load incoming power supply side 300 and the grid power distribution load side 200, and mainly includes the user isolating switch 13 connected to the user load incoming power supply side 300 and the connection station The distribution network load switch 11 on the power distribution load side 200 of the power grid is described.

[0020] refer to figure 2 , in a preferred embodiment of the present invention, the user boundary switch 100 is divided into two parts: a toggle switch (that is, a switch part composed of components 11, 12 and 13) and an electric board 400, wherein the electric board 400 can easily pass through the user's boundary The data interface provided on the switch 100, such as the operation panel 42, controls the action of the switch, isolates and shields the strong current part, and leads the weak current terminal to the separated electric b...

Abstract

The invention discloses an electric power user demarcation load switch with encryption communication function, which is connected between the power supply side of the user load incoming line and the power distribution load side of the grid, and includes an independent pluggable electric board, which is provided with AC sampling Terminal, CPU, control output terminal, and an operation panel for command input, and a wireless communication terminal for accessing the main station for on-line monitoring of power distribution lines. The operation panel and wireless communication terminal are connected to the CPU. The wireless communication terminal is further coupled with an encryption chip, through which the encryption chip is connected to the security access terminal of the power distribution network, and after decoding the access information of the connected power user boundary load switch through the security access terminal, The decoded information is transmitted to the distribution line on-line monitoring master station, and the communication with the power user boundary load switch is established.

Description

technical field [0001] The invention relates to an improvement of a power user boundary load switch, which is used to solve the control safety of the load switch. Background technique [0002] The power user boundary load switch is installed at the property right boundary point between the power company and the user side, and can play a good role in regional isolation in the case of internal faults on the user side. This product has been installed and applied. The traditional user boundary switch does not have a communication function or directly uses clear text communication, which cannot meet the new requirements of the power grid for information security protection and wireless terminal installation and access. Data cannot be shared and integrated. [0003] As a main component of a power supply system, it is very important to balance the load distribution among the phase lines in the three-phase power supply line. economic and security issues. Due to the unbalanced thr...
