Problems solved by technology

[0004] The above-mentioned prior art has the following shortcomings: 1. The relationship between the stopper and the first and second lances is a squeeze relationship, and long-term use is easy to cause damage to the stopper, the stopper and the first and second lances, Resulting in equipment failure; 2. The protruding length of the baffle cannot be adjusted, and it is inconvenient to replace; 3. The control situation cannot be further confirmed on site

Abstract

The invention belongs to the field of power equipment control, and particularly relates to a sequential control device of an isolating switch for a 110kV GIS substation. The device consists of a detection unit, a control unit, an execution unit and firmware, the detection unit is used for receiving a signal and transmitting the signal to the control unit, the control unit analyzes the received signal and controls the action of the execution unit according to the received signal, the firmware comprises a protection device, a test device, a metering device and the like, the sequential control device is characterized by further comprising a first fixing shaft, a connecting rod, a second fixing shaft, a travel switch fixing frame and two travel switches, the travel switch is connected with a travel switch swing rod, the connecting rod is fixed at one end of the first fixing shaft, the other end of the connecting rod is fixed at one end of the second fixing shaft, the second fixing shaft is connected with a disconnecting link, and the other end of the first fixing shaft is connected with the execution unit. The sequential control device has the advantages of being more accurate in criterion confirmation, safe, reliable, long in service life, convenient to use and the like.

Description

technical field [0001] The invention belongs to the field of power equipment control, and in particular relates to a sequential control device for an isolating switch used in a 110kV GIS substation. Background technique [0002] In 2014, the State Grid proposed new safety regulations for electrical equipment in substations, requiring that the position detection of electrical equipment after operation should be based on the actual position of each phase of the equipment. When the actual position cannot be seen, indirect methods should be used, such as equipment machinery Position indication, electrical indication, electrification display device, instrument and various telemetry, remote signaling and other signal changes to judge. When judging, at least two indications of different principles or non-homologous sources should have corresponding changes, and all these determined indications have changed at the same time, so that it can be confirmed that the equipment has been op...
