Embodiment Construction

[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] It should be noted that the sensor fixing device of the present invention is used to be fixedly installed on the rotating part on the disconnector that is consistent with the movement rule of the moving contact arm. Before introducing the specific embodiment of the sensor fixing device of the present invention, first introduce the structure of one of the isolating switches adapted to the sensor fixing device in this embodiment: as figure 1 and figure 2 As shown, the isolating switch includes an insulating support column 3 and a movable contact arm (not shown) at the top of the insulating support column 3. The insulating support column 3 can rotate around its axis, thereby driving the movable contact arm to swing to realize the separation of the movable contact arm. Closing action. The isolating switch also includes a transmission mechanism that...

Abstract

The invention relates to a sensor fixing device. The sensor fixing device comprises a first clamping block and a second clamping block. The two clamping blocks are matched with each other and are usedfor clamping a rotating piece on a corresponding isolating switch, an elastic piece for keeping the first clamping block and the second clamping block clamp the rotating piece is arranged between thefirst clamping block and the second clamping block, a posture sensor for detecting the moving state of the rotating piece is fixed to the first clamping block or the second clamping block, and the two clamping blocks are each provided with a clamp matching part used for being matched with a dismounting clamp to enable the two clamping blocks to overcome the elastic force to release the clamping effect on the rotating piece. Through the cooperation of the dismounting clamp and the sensor fixing device, the sensor fixing device can clamp a crank arm rotating piece under the action of the elastic force or release the clamping of the sensor fixing device on the crank arm rotating piece under the action of the dismounting clamp, thereby realizing the mounting and dismounting of the sensor fixing device under the condition that the isolating switch is not powered off.

Description

technical field [0001] The invention relates to a sensor fixing device. Background technique [0002] The isolating switch includes an operating mechanism, a transmission mechanism and a movable contact arm on the insulating support column. The transmission mechanism transmits power to the insulating support column, and through the swing of the insulating support column, the opening and closing of the movable contact arm on the insulating support column is realized. Brake action, the transmission mechanism generally includes rotating parts that drive the action of the moving contact to realize the opening and closing of the moving contact, such as the commonly used crank arm, transmission shaft, etc. For the safety of power grid operation or personal safety during power grid maintenance, a detection device for detecting whether the moving contact arm is in place is installed on the isolating switch in the industry. In the prior art, the above detection device is generally in...
