Problems solved by technology

Among them, the opening and closing operation of the isolation switch driven by the axial rotation of the long connecting rod is a relatively complicated transmission system. The cross section of the long connecting rod is hexagonal, and the angular displacement sensor cannot be directly placed on the long connecting rod.
Therefore, there is inconvenience in operation, the weak point that work efficiency is low

Embodiment 1

[0036] The invention is a fixed bracket for an angular displacement sensor of a GIS isolating switch reliability analyzer. On the long connecting rod for opening and closing operations. The specific structure is as figure 1 as shown, figure 1 It is a structural schematic diagram of the present invention.

[0037] The fixed bracket for the angular displacement sensor of the GIS isolating switch reliability analyzer of the present invention is composed of four parts: a half-moon clip 1, a fastening bolt 2, a rotating shaft, and a lock 3. Wherein, the half-moon clip 1 is used to contact the angular displacement sensor, and the rotation of the half-moon clip 1 drives the rotation of the angular displacement sensor, and the rotation angle of the long connecting rod is converted through the proportional relationship between the two radii. The fastening bolt 2 is used to fix the half-moon clip 1 and the long connecting rod.

[0038] The concrete connection relation of the present...

Embodiment 2

[0042] The present invention also provides an embodiment, a fixed bracket for the angular displacement sensor of a GIS isolating switch reliability analyzer, through which the transition is made through the fixed bracket, and the angular displacement sensor is driven by the fixed bracket to indirectly test the rotation angle of the long connecting rod . During the specific implementation, the operation steps and principles are as follows:

[0043] Step 1. Screw all fastening bolts 2 into the threaded holes inside the half-moon clip 1;

[0044] Step 2. Open the lock 3, hold the upper and lower parts of the half-moon clip 1 with both hands, put the half-moon clip 1 over the long connecting rod of the GIS isolation switch mechanism to be tested, and lock the lock 3;

[0045] Step 3. Make the side of the bracket with sawtooth face the angular displacement sensor, and make the hexagonal sides in the bracket parallel to the six faces of the cross-section of the long connecting rod;...

Abstract

The invention belongs to the technical field of power equipment test instruments, and relates to a fixing bracket for an angular displacement sensor of a GIS disconnecting switch reliability analyzer,which is suitable for being used as the support for the angular displacement sensor fixed on a transmission connecting rod of an isolation switch mechanism when switching-on and switching-off actioncharacteristics of the isolation switch in power equipment GIS is detected. The bracket comprises two half-moon-shaped clamps, and the two half-moon-shaped clamps are of an up-down structure and are connected into a whole through a lock catch. The bracket has the characteristics of small size, light weight, simplicity in operation and firmness in fixation. When the switching-on and switching-off action characteristics of the isolation switch in the power equipment GIS are detected, an angular displacement sensor is fixed on a long connecting rod which drives the isolation switch to be switchedon and off through the long connecting rod. The device is wide in application range, can be suitable for operation and maintenance departments of power grid companies, test detection parts, switch equipment manufacturers and other units, and brings certain economic benefits and social benefits to enterprises.

Description

technical field [0001] The invention belongs to the technical field of power equipment testing instruments, and relates to a fixed bracket for an angular displacement sensor of a GIS isolating switch reliability analyzer, which is suitable for detecting the opening and closing action characteristics of the isolating switch in the GIS of the power equipment, and is fixed to the transmission of the isolating switch mechanism. Bracket for angular displacement sensor on connecting rod. Background technique [0002] The Chinese name of GIS is a fully enclosed gas-insulated combined electrical appliance, and the English name is Gas Insulated Substation, referred to as GIS. GIS encapsulates circuit breakers, isolating switches, grounding switches, voltage transformers, busbars and other equipment components in a metal shell, and charges a certain pressure. SF 6 Gas acts as insulation. [0003] At present, GIS has been widely used in the power system. Most of the new substations a...
