Embodiment Construction

[0016] Embodiment of the present invention: when adopting the power supply continuous power supply guarantee method of single bus segment wiring of the present invention, the existing microcomputer protection devices of No. 1 incoming line and No. 2 incoming line in the prior art are used, and The data of incoming line and incoming line No. 2 and the on-off information of circuit breaker and bus tie switch of incoming line No. 1 and incoming line No. 2 are respectively input to the microcomputer protection device, and the control program of the microcomputer protection device is set to output the execution signal control. Automatic conversion of circuit breakers and bus tie switches of incoming line No. 1 and incoming line No. 2 to realize the function of standby self-switching. It completes the following two functions: one is: when the first and second incoming lines are running separately, and any incoming line is powered off, the present invention makes the bus tie switch cl...

Abstract

An existed microcomputer protective device for No.1 incoming line and No.2 incoming line are used to input the data of No.1 incoming line and No.2 incoming line and the onoff message of breaker and busbar link switch of No.1 incoming line and No.2 incoming line into the microcomputer protective device, and through setting a control program for microcomputer protective device, the output signals are outputted to execute automatic switching of breaker and busbar link switch of No.1 incoming line and No.2 incoming line, and to implement standby power supply self-closing.

Description

technical field [0001] The invention relates to a continuous power supply guarantee method and device for a single busbar segmented connection, and belongs to the technical field of the guarantee of continuous power supply of a power supply. Background technique [0002] In the medium-voltage (6 / 10kV) power supply system of the electrolytic aluminum plant, the main wiring adopts the method of single-bus sectional wiring. Each power distribution station has two incoming lines, and each incoming line is equipped with a circuit breaker. There is a bus tie switch between the two bus bars. When the power supply of the No. 1 incoming line is cut off, the power of the No. 2 incoming line is automatically turned on; or the two bus bars are connected through the bus tie switch to ensure the continuity of the power supply of the system. and reliability. figure 1 It is a typical single bus segment wiring diagram. [0003] At present, the guarantee system of continuous power supply of...
